Unveiling the Lift and Shift Cloud Migration Paradigm - Certbolt

The journey towards digital transformation is increasingly characterized by the strategic adoption of cloud computing. Organizations globally are recognizing the imperative of migrating their operations to the cloud to achieve unparalleled efficiency and agility. However, this transition, even for seasoned cloud professionals, often presents a complex array of challenges. These hurdles can encompass data security, seamless integration with external systems, managing legacy applications, optimizing costs, and securing a workforce equipped with specialized cloud experts.

The Lift and Shift migration strategy emerges as a potent solution to these multifaceted challenges. This approach, also known as re-hosting, fundamentally involves the relocation of existing infrastructure and applications to a cloud environment with minimal, if any, architectural modifications. The essence of this strategy lies in transposing the application, its accompanying middleware, and the underlying database directly to a cloud platform. Typically, these applications are subsequently run within virtual machines (VMs) or containers in their new cloud domicile.

The overarching objective of the Lift and Shift methodology is to harness the inherent advantages offered by cloud computing, notably its remarkable scalability, intrinsic flexibility, and significant cost-saving potential. A cornerstone of this strategy is the deliberate avoidance of substantial alterations to an application’s architecture or its foundational code. This enables a remarkably smooth and uninterrupted transfer of the application and its entire infrastructure to the chosen cloud milieu. The capacity to deploy applications on virtual machines or containers within the cloud environment underscores the adaptability of this approach. Consequently, businesses can effectuate a swift migration of their extant applications to the cloud without the onerous requirement for extensive re-architecting or laborious refactoring processes, thereby accelerating their cloud adoption timeline.

When to Utilize the Lift and Shift Approach in Cloud Migration

The Lift and Shift method, also referred to as rehosting, is a cloud migration strategy that involves moving applications, workloads, and data from on-premises or legacy environments directly into the cloud infrastructure with minimal or no alteration. While not suitable for every scenario, this approach is especially valuable under certain business, operational, and technical conditions. Understanding the ideal context for Lift and Shift can help organizations achieve rapid modernization without overhauling their entire architecture.

Scenarios That Demand Swift Deployment

One of the most compelling use cases for Lift and Shift is when time is of the essence. Enterprises facing tight deadlines—whether due to a data center contract expiring, a merger or acquisition, or an executive mandate for cloud transformation—often lean on this strategy to expedite migration. The simplicity of this model reduces planning complexity, as there’s no immediate need to refactor applications or reengineer system components. By preserving the original application structure, businesses can establish a cloud footprint quickly, minimizing downtime and accelerating their transition timeline.

Organizations operating in fast-paced industries such as e-commerce, finance, and digital media often find this approach beneficial when launching new services in regions where time-to-market provides a competitive advantage. Rather than delaying product rollouts due to protracted development cycles, Lift and Shift empowers teams to migrate legacy systems and rapidly scale them in a cloud-native environment.

Preserving System Stability with Minimal Adjustments

Another scenario where Lift and Shift emerges as the preferred strategy is when there is a high risk associated with modifying existing systems. For companies running mission-critical applications that require precise uptime and predictable performance, making architectural or code-level changes can introduce unnecessary risk. This approach helps preserve stability by replicating existing environments within the cloud as closely as possible.

This method is especially relevant in heavily regulated sectors—such as healthcare, finance, and government—where compliance requirements may restrict alterations to production systems. In such environments, Lift and Shift facilitates modernization without disrupting compliance frameworks or jeopardizing audit trails. The integrity of existing security controls, monitoring systems, and access policies can be maintained while taking advantage of cloud elasticity and scalability.

Moreover, some enterprises operate with bespoke legacy software solutions that may not support replatforming or refactoring without extensive redevelopment. In these instances, Lift and Shift ensures these systems continue to operate reliably in a modern hosting infrastructure without the need for rewriting or replacing large volumes of code.

Seamless Transition from Virtualized or Containerized Environments

Lift and Shift is particularly effective for workloads that are already hosted within virtual machines (VMs) or containers. Because cloud platforms like AWS, Azure, and Google Cloud provide native support for virtualization and container orchestration, moving such workloads often involves straightforward image replication and deployment.

For example, VMware-based infrastructures can be seamlessly mirrored into cloud-based VMware offerings, while Docker containers can be easily hosted using managed services such as Amazon ECS, Azure Container Instances, or Google Kubernetes Engine. The compatibility between legacy VM/containerized deployments and cloud infrastructure ensures minimal reconfiguration, thereby streamlining the migration journey.

Organizations already leveraging DevOps practices, CI/CD pipelines, and infrastructure-as-code tools such as Terraform or CloudFormation can automate much of the rehosting process, accelerating deployment while ensuring consistency and reducing human error.

Extended Business Use Cases Supporting Lift and Shift

To further illuminate the practicality of this strategy, it’s helpful to examine business-driven scenarios where Lift and Shift serves as a tactical solution to strategic problems.

Data Center Closure or Lease Expiration

Many organizations are transitioning away from traditional data centers as part of a broader digital transformation initiative. When physical server leases or facility contracts are set to expire, time constraints make application redevelopment impractical. In such cases, Lift and Shift enables organizations to move existing workloads to the cloud promptly, avoiding disruption of operations while postponing the effort needed to re-architect for long-term efficiency.

By transferring their digital assets into the cloud, businesses not only avoid data center renewal fees but also gain the agility to later transform their applications incrementally once stability is ensured in the new environment.

Disaster Recovery and Business Continuity

Another compelling use case is the establishment of disaster recovery (DR) environments. Rehosting workloads to the cloud as secondary or backup systems can significantly reduce the cost and complexity associated with traditional DR setups. In a Lift and Shift model, replicas of mission-critical workloads can be hosted in geographically isolated cloud regions, ensuring business continuity in the event of outages, cyberattacks, or natural disasters.

This model also supports elastic scaling in DR situations, allowing businesses to scale resources on-demand and pay only for what they use, instead of investing in idle, on-premises infrastructure.

Mergers and Acquisitions

When two companies merge, integrating IT systems can be complex and time-consuming. The Lift and Shift method allows one or both organizations to rapidly consolidate or migrate their existing applications into a unified cloud environment. This temporary migration strategy helps IT teams stabilize systems post-acquisition, ensuring continuous service delivery while deferring major integration or modernization efforts.

Lift and Shift can also enable shared services platforms across subsidiaries, reducing the operational burden and establishing a consistent security and compliance posture across business units.

Advantages of Choosing Lift and Shift

Though often viewed as a transitional strategy, the Lift and Shift approach offers several notable benefits that can serve as foundational steps toward future optimization.

Cost Predictability and Initial Savings

Rehosting applications without significant modification can lead to initial cost reductions, especially by eliminating the need to maintain expensive on-premises infrastructure. While these savings may be short-term—particularly if the applications are not optimized for cloud resource consumption—they provide an opportunity for financial reprieve while longer-term digital strategies are defined.

Additionally, Lift and Shift allows for predictable budgeting, as organizations typically know the resource consumption patterns of their existing applications and can align cloud provisioning accordingly.

Accelerated Cloud Familiarity

For teams that are new to cloud computing, Lift and Shift serves as an entry point into the ecosystem. It allows engineers, developers, and administrators to acclimate to cloud tools and processes without immediately needing to master advanced cloud-native paradigms. Over time, as internal skill sets mature, these same teams can then refactor and rearchitect their workloads with greater confidence and competence.

This phased learning approach fosters gradual adoption, helping organizations avoid the steep learning curves and potential pitfalls that can come with full replatforming or rebuilding.

Recognizing the Limitations and Planning for the Future

Despite its many advantages, Lift and Shift should not be considered the final destination in cloud transformation. Applications rehosted without optimization may not fully benefit from cost savings or performance enhancements offered by the cloud. Overprovisioning, security gaps, and inefficient architecture can persist if workloads are not eventually assessed and evolved.

Therefore, organizations should view Lift and Shift as the first step in a multi-phase journey. Once stability and continuity are achieved, businesses can revisit these applications to identify modernization opportunities. This may involve converting monolithic applications into microservices, implementing serverless functions, or transitioning databases to fully managed offerings.

Strategic use of monitoring and observability tools post-migration—such as AWS CloudWatch, Azure Monitor, or Google Operations Suite—can aid in identifying inefficiencies and guiding iterative improvements.

Unlocking the Strategic Depth of the Lift and Shift Cloud Migration Model

Embracing the Lift and Shift model for migrating to the cloud delivers a constellation of tactical and operational advantages. This methodology, often recognized for its speed and simplicity, provides organizations with a streamlined gateway to digital transformation while preserving legacy systems. Without necessitating substantial architectural reengineering, this approach enables a rapid transition that amplifies efficiency, agility, and cost optimization.

Accelerating Cloud Migration with Minimal Overhead

At the heart of the Lift and Shift approach lies its inherent efficiency in transitioning workloads to the cloud without reconfiguring the application’s internal framework. By transferring existing systems in their entirety—often as virtual machine images or containerized services—businesses sidestep time-intensive redesign phases that typically accompany more intricate migration techniques.

The minimal disruption characteristic of this model offers significant tactical appeal. Organizations facing urgent digital transformation demands, constrained timelines, or inflexible legacy environments can seamlessly elevate their applications into cloud ecosystems. For example, a mission-critical customer relationship management system running on traditional infrastructure can be migrated intact using virtual machines, eliminating the need for laborious code modifications or extensive compatibility testing.

This expeditious migration reduces friction, enabling organizations to maintain operational momentum while capitalizing on the cloud’s inherent elasticity and resilience. This approach also mitigates risks commonly associated with large-scale system overhauls by preserving proven functionalities in a new hosting environment.

Optimizing Cloud Economics Through Strategic Deployment

Cost-effectiveness remains one of the hallmark benefits of Lift and Shift migrations. By relocating applications and infrastructure to scalable cloud platforms, organizations can significantly reduce capital expenditures tied to hardware acquisition, on-premises maintenance, and system upkeep.

Cloud platforms utilize pay-as-you-go models, enabling enterprises to only pay for resources they actively consume. This usage-based model starkly contrasts with the upfront investments and depreciation schedules of physical infrastructure, creating immediate budgetary relief.

Moreover, cloud providers extend cost-management tools that offer granular visibility into resource utilization. These capabilities empower organizations to identify underutilized assets, right-size their virtual environments, and orchestrate cost-saving strategies. A migrated application, once monitored via integrated analytics dashboards, can be calibrated for performance and expenditure, ensuring optimal return on investment across all operational tiers.

Additionally, by centralizing infrastructure in a cloud environment, enterprises benefit from automated updates, security patches, and maintenance, which collectively reduce the burden on internal IT departments and trim long-term operational costs.

Gaining Agile Scalability and Responsive Resource Allocation

The Lift and Shift paradigm grants businesses immediate access to cloud-native scalability—an essential asset in today’s rapidly evolving digital landscape. Once an application resides in the cloud, it gains access to a plethora of services capable of dynamically adjusting computational power, storage, and networking resources in real time.

Auto-scaling mechanisms offered by cloud platforms detect application load fluctuations and automatically adjust resource provisioning accordingly. This ensures peak application performance during high-traffic periods and conserves costs during low-demand windows. For instance, an e-commerce platform migrated using Lift and Shift can effortlessly handle a surge in visitors during promotional sales, scaling up resources in real time to maintain responsiveness and uptime.

Such elasticity enhances both user experience and operational efficiency, allowing organizations to serve global audiences with precision and speed. More importantly, this capability is provisioned without human intervention, ensuring that scalability becomes a proactive, intelligent process rather than a reactive manual effort.

Ensuring Operational Continuity and Elevated Uptime Standards

Business continuity and high availability are critical to maintaining user trust and preventing revenue loss. Cloud platforms offer built-in architectures that support fault tolerance and disaster recovery at scale. The Lift and Shift strategy allows enterprises to inherit these robust architectures without having to reengineer existing applications.

By leveraging availability zones, geographic redundancy, and automatic failover protocols, organizations can construct resilient systems that remain operational despite hardware failures or regional outages. For instance, a cloud-hosted relational database using Multi-AZ deployment ensures that if one instance fails, a secondary instance instantly assumes control, thereby maintaining seamless access for end-users.

This approach is particularly valuable for industries reliant on continuous data accessibility, such as finance, healthcare, and telecommunications. The automated nature of failover, recovery, and load balancing mechanisms fosters an environment where applications are resilient by design, reinforcing trust and safeguarding revenue streams.

Strengthening Cybersecurity and Regulatory Alignment in the Cloud

Cybersecurity remains an indispensable pillar of modern enterprise architecture. Migrating via Lift and Shift enables organizations to benefit from the hardened security frameworks inherent to major cloud platforms. These providers deliver advanced security architectures that often surpass traditional on-premises solutions in both depth and flexibility.

Key offerings include real-time threat detection, encrypted data transmission, identity federation, multi-factor authentication, and granular access controls. For instance, implementing disk-level encryption on cloud-based virtual machines ensures that sensitive data is shielded both in transit and at rest. Organizations operating under stringent regulatory conditions—such as GDPR, HIPAA, or PCI DSS—can leverage predefined compliance templates and audit-ready reporting tools to demonstrate conformance.

Additionally, centralized identity and access management systems empower security teams to enforce least-privilege policies and role-based access at scale. The ability to segment network access and monitor activities through consolidated dashboards enhances visibility and control over the entire IT estate.

With these features readily available, organizations not only elevate their security postures but also minimize the costs and complexities associated with managing compliance in-house. Lift and Shift becomes more than just a migration tool—it transforms into a strategic vehicle for digital risk mitigation.

Achieving Rapid ROI and Business Agility

In an era where adaptability often dictates market survival, the Lift and Shift strategy allows businesses to unlock rapid returns on investment. With minimal downtime and fewer configuration hurdles, organizations can integrate cloud services into their operational workflows at an accelerated pace.

This rapid time-to-value positions enterprises to innovate and iterate more freely. By offloading infrastructure concerns to cloud platforms, internal teams can concentrate on application enhancement, feature development, and strategic initiatives. This redistribution of effort fosters an innovation-friendly culture that is unencumbered by the limitations of physical infrastructure.

Moreover, the agility afforded by cloud migration enables enterprises to respond to market shifts and consumer behavior with unprecedented speed. Whether launching a new service, entering a new geographic region, or scaling infrastructure to support viral growth, the Lift and Shift method ensures that organizations can execute decisively and efficiently.

Simplifying Disaster Recovery and Business Resilience Strategies

Disaster recovery planning is an intrinsic requirement for enterprise sustainability. Traditionally, creating reliable failover systems required a complex web of replication, backup servers, and geographically dispersed data centers. The Lift and Shift model dramatically simplifies this equation.

Cloud platforms provide native backup, replication, and snapshotting tools that can be configured with minimal effort. These tools allow for automatic backups of mission-critical applications and near-instantaneous restoration in the event of failure. With regional and multi-region support, organizations can craft robust recovery plans without the prohibitive costs associated with physical redundancy.

This not only bolsters confidence in the organization’s disaster preparedness but also complies with the increasingly rigorous data protection standards imposed by regulators and industry bodies.

Establishing a Foundation for Future Cloud-Native Modernization

While Lift and Shift is often viewed as a tactical migration strategy, it also lays the groundwork for future modernization. Once in the cloud, applications can be incrementally re-architected to leverage microservices, containerization, serverless functions, and other advanced paradigms without incurring the costs and risks of a wholesale transformation.

This phased modernization approach aligns with agile methodologies and reduces the resistance typically encountered during major IT overhauls. Enterprises can experiment with new technologies in isolated environments, gradually refactoring components of their applications into cloud-native services. This allows for innovation at the pace of business need, ensuring strategic alignment and continuity.

Evaluating Lift-and-Shift in Relation to Other Cloud Migration Strategies

Understanding the true merit of the lift-and-shift methodology necessitates a direct comparison with other widely adopted cloud migration frameworks. When selecting the most appropriate migration path for a given workload, it is essential to examine key contrasts between lift-and-shift and alternate paradigms like re-platforming, re-architecting, and platform-as-a-service (PaaS) migrations. This exploration sheds light on when lift-and-shift emerges as the most practical route and when other models might better serve operational goals.

Dissecting Lift-and-Shift and PaaS Migration Methodologies

To comprehend the strategic divergence between these two migration philosophies, a detailed evaluation across various domains such as technical intricacy, operational control, deployment timelines, cost structures, and required expertise becomes imperative.

Comparing Architectural Intricacy

At its core, lift-and-shift is defined by its elemental simplicity. This method facilitates the transition of applications and their encompassing infrastructure from on-premises environments to the cloud with minimal to no modification. Such a «plug-and-play» transfer appeals particularly to enterprises seeking swift digital transformation without entangling themselves in extensive re-engineering efforts.

By contrast, PaaS migration requires substantial re-architecture. Applications must be retrofitted or sometimes even entirely restructured to comply with the unique paradigms of the cloud platform. This includes aligning with platform-native APIs, altering deployment workflows, and potentially rewriting components to exploit the full breadth of platform features. While this process paves the way for longer-term scalability and optimization, it is more complex and time-intensive.

Application Oversight and Operational Autonomy

A pivotal distinction between lift-and-shift and PaaS emerges in the realm of application governance. When adopting a lift-and-shift model, organizations maintain full stewardship over the software stack — from the application layer through middleware to the virtualized infrastructure. This level of granular oversight offers maximum configurability and customization, which is ideal for organizations with sophisticated legacy systems or compliance-intensive workloads.

On the other hand, PaaS abstracts much of the operational complexity. The service provider assumes responsibility for managing the underlying runtime, middleware, and compute resources. While this significantly reduces the burden of routine maintenance and infrastructure administration, it can simultaneously limit the degree of control and customization available to development teams.

Flexibility and Ecosystem Integration

PaaS environments are inherently rich in integrated services. From auto-scaling databases and orchestrated container platforms to embedded CI/CD pipelines and intelligent caching, these ecosystems empower developers to innovate without concerning themselves with foundational setup tasks. These pre-configured capabilities enable rapid prototyping and modular system design, enhancing adaptability in rapidly evolving markets.

In contrast, the lift-and-shift approach offers minimal out-of-the-box integrations. While organizations are still able to utilize cloud-native services, the responsibility of provisioning, configuring, and linking these components falls squarely on internal teams. For enterprises seeking complete autonomy or those migrating tightly coupled legacy stacks, this DIY structure may be more desirable.

Budgetary Considerations and Financial Optimization

From a financial lens, lift-and-shift often garners attention due to its comparatively low upfront costs. The absence of architectural refactoring translates into reduced development expenditure and faster migration cycles, which in turn minimize disruption and opportunity cost. Furthermore, capital investments in legacy infrastructure can be preserved during the migration process.

Conversely, PaaS introduces variable costs tied to both its development overhead and ongoing service consumption. While its managed nature can yield operational savings over time — especially through reduced staffing needs — the initial investment in codebase refactoring, integration testing, and training may present a formidable barrier for resource-constrained enterprises.

Timeframe for Deployment and Business Continuity

For organizations prioritizing speed, lift-and-shift typically offers a faster path to cloud adoption. Since the existing application logic remains largely intact, enterprises can achieve cloud-readiness in a matter of days or weeks, rather than months. This expediency makes lift-and-shift particularly suitable for time-sensitive migrations, mergers and acquisitions, or disaster recovery implementations.

PaaS, in contrast, demands a more prolonged deployment period. The restructuring and validation of applications to align with platform specifications can delay launch timelines. However, this delay is often offset by long-term gains in automation, resilience, and scalability.

Expertise and Skillset Requirements

Lift-and-shift demands relatively modest cloud acumen. Teams familiar with the existing infrastructure can carry out the migration with limited training or external assistance. This allows organizations to leverage their current workforce, ensuring business continuity and cost efficiency.

On the flip side, effective PaaS adoption hinges on specialized knowledge. Teams must be proficient in container orchestration, platform-specific APIs, security models, and service mesh architectures. This steep learning curve may necessitate new hires or external consultants, which can extend both timeline and budget.

Assessing Strategic Suitability: When to Choose Lift-and-Shift

The decision to employ lift-and-shift is rarely black and white. Rather, it is contextually driven, shaped by the organization’s objectives, infrastructure maturity, and resource availability.

For enterprises with monolithic applications tightly coupled to legacy systems, lift-and-shift serves as a transitional bridge. It allows for immediate cloud onboarding without dismantling proven architectures. This interim strategy enables businesses to harness cloud scalability, geographic redundancy, and usage-based billing without abandoning established workflows.

Moreover, lift-and-shift is often the most viable choice in regulatory contexts. In industries such as healthcare, banking, or public services, data sovereignty and compliance mandates often require full visibility and control over application stacks. Migrating existing setups with minimal change ensures continued adherence to policy frameworks.

Additionally, organizations seeking to modernize incrementally can benefit from starting with a lift-and-shift model. Once operational stability is achieved in the cloud, they can gradually introduce platform optimizations, decoupling components or migrating specific services to PaaS or serverless models over time.

When PaaS Becomes a Superior Alternative

While lift-and-shift provides a rapid and controlled entry into the cloud, PaaS shines in environments where innovation, agility, and operational efficiency are paramount. Startups, greenfield projects, and digital-first organizations can capitalize on the advanced automation and rich integrations PaaS environments offer. These features eliminate much of the operational toil, allowing teams to focus on development velocity and customer-centric features.

PaaS also offers architectural elegance. Microservices can be deployed and scaled independently, updates can be rolled out with zero downtime, and observability tools offer real-time insight into application health. In scenarios where customer experience and responsiveness are business-critical, the advantages of PaaS often outweigh the higher complexity and cost.

Limitations and Risks of Lift-and-Shift

Despite its strengths, lift-and-shift is not without limitations. One of the most pressing concerns is technical debt. By moving applications to the cloud without optimization, organizations risk replicating inefficiencies in a new environment. These latent inefficiencies can lead to performance bottlenecks, underutilized resources, and inflated operational costs.

Additionally, the cloud’s full potential may remain untapped. Without embracing elasticity, distributed architectures, and native integrations, lift-and-shift deployments may mimic the rigidity of traditional data centers. This often leads to missed opportunities in cost optimization, high availability, and continuous delivery.

Security must also be carefully considered. Legacy applications may lack modern encryption, authentication, and logging mechanisms. Simply relocating such systems to the cloud does not automatically enhance their security posture — in some cases, it may even expose new vulnerabilities if proper controls are not implemented.

Hybrid Approaches: Combining Strategies for Optimal Outcomes

In many cases, a blended approach yields the most favorable results. Organizations can begin with lift-and-shift to secure a foothold in the cloud, followed by targeted re-platforming or refactoring of individual components.

For instance, a monolithic application can be migrated as-is using lift-and-shift, while auxiliary services like authentication, search, or reporting are restructured into microservices or transitioned to PaaS environments. This hybrid model offers both speed and long-term strategic value.

Incremental modernization also reduces migration risk. By avoiding sweeping architectural changes upfront, organizations can test the waters, refine their strategy, and build institutional knowledge over time.

Lift and Shift Versus SaaS (Software as a Service) Migration

A concise comparison between SaaS-based migration and Lift and Shift migration reveals distinct differences in scope, control, customizability, deployment time, cost structures, and maintenance responsibilities.

Scope of Migration: In a Lift and Shift migration, the entirety of an organization’s application stack, encompassing the application code, its supporting infrastructure, various integrations, the database, and the foundational platform, is comprehensively transferred to the cloud environment. Conversely, SaaS migration specifically pertains to the relocation of a particular application or service to a pre-existing cloud-based SaaS provider.
Level of Control: With Lift and Shift, organizations retain absolute control over the application and its underlying infrastructure, assuming full responsibility for their management and maintenance. In the context of SaaS, an organization cedes a significant degree of control over the application, relying entirely on the SaaS provider for its operation, maintenance, and ongoing management.
Customization Capabilities: Lift and Shift migration affords organizations the considerable latitude to extensively customize their application and infrastructure to precisely align with their unique and specific operational requirements. In contrast, with SaaS migration, the organization’s capacity for customization is often constrained, being largely dependent on the pre-defined features and functionalities offered by the SaaS provider.
Time to Deployment: Lift and Shift migration typically offers a quicker deployment timeline, as businesses can rapidly transfer their current apps to the cloud with minimal delays. Conversely, SaaS migration may necessitate a longer deployment period, primarily because organizations might need to invest time in adapting and customizing the chosen SaaS solution to seamlessly integrate with their existing technical infrastructure and satisfy their specific business needs.
Cost Structures: For enterprises that have already made substantial capital investments in on-premises hardware and infrastructure, Lift and Shift migration often proves to be the more cost-effective solution. Conversely, SaaS migration can present a more economical option for organizations that prefer to avoid significant upfront investments in on-premises hardware and infrastructure, as they can conveniently pay for the service on a recurring monthly or annual subscription basis.
Maintenance Responsibilities: With Lift and Shift migration, businesses assume direct oversight and ongoing maintenance responsibilities for their cloud-based applications and the associated infrastructure. When a company migrates to SaaS, the SaaS provider takes over the comprehensive management and maintenance of the migration, which can reduce the organization’s maintenance workload.

Ultimately, the choice between SaaS migration and Lift and Shift is contingent upon an organization’s unique operational needs and specific requirements. Lift and Shift migration is ideally suited for businesses aiming to rapidly and affordably transition their existing applications to the cloud while maintaining complete autonomy over their infrastructure and applications. Conversely, SaaS migration is a more appropriate choice for organizations that prefer to leverage a fully managed, cloud-based service provided by a third party, seeking to minimize their internal maintenance workload and associated complexities.
