Understanding VPC Endpoints in AWS: Interface vs Gateway

Amazon Web Services (AWS) offers VPC (Virtual Private Cloud) endpoints to facilitate secure and efficient communication between your VPC and AWS services without sending traffic over the public internet. By leveraging PrivateLink technology, VPC endpoints enable private connectivity, significantly improving security and reducing latency.

There are two primary types of VPC endpoints: interface endpoints and gateway endpoints. Each is designed for specific use cases, and understanding the nuances between them is vital for constructing robust cloud architectures.

Understanding the Functionality of Interface Endpoints in Virtual Private Clouds

Within the landscape of Amazon Web Services (AWS), interface endpoints play a vital role in enabling secure, private communication between your Virtual Private Cloud (VPC) and numerous AWS-managed services. An interface endpoint functions as an Elastic Network Interface (ENI) that is automatically provisioned with a private IP address. This IP address is drawn directly from the subnet range you designate during the configuration process. This strategic placement of the ENI allows internal VPC resources to interact with AWS services seamlessly and securely.

Once the interface endpoint is deployed, any interaction between your VPC and supported AWS services, such as Amazon CloudFormation, Amazon SNS, or Amazon S3, is confined entirely within the AWS infrastructure. There is no need for the traffic to traverse the public internet, which dramatically reduces potential exposure to external malicious threats. This model ensures both data sovereignty and consistent performance, as it mitigates the latencies associated with internet-based routing.

Interface endpoints are especially instrumental when a VPC needs to establish private connectivity with third-party SaaS applications hosted within AWS Partner VPCs. These SaaS services, often residing in separate AWS accounts, expose their resources via AWS PrivateLink. The interface endpoint, by linking with these services, allows direct access using private IP addresses.

Security is reinforced by attaching the interface endpoint to security groups that control which traffic is allowed in and out. These configurations mirror the same principles as securing EC2 instances, offering administrators full autonomy over data ingress and egress.

However, this sophisticated private networking is not free of cost. AWS bills interface endpoints based on two main factors: an hourly rate for endpoint availability and data processing charges for the volume of data transferred via PrivateLink. Organizations must evaluate their budget and data transfer patterns when scaling the use of interface endpoints across multiple services or accounts.

In large-scale architectures where data confidentiality, performance, and compliance are paramount, leveraging interface endpoints becomes indispensable. Not only does it align with stringent security postures, but it also fosters predictable network behavior—an essential attribute for enterprise-grade applications.

How VPC Interface Endpoints Operate Within AWS Architecture

Virtual Private Cloud (VPC) Interface Endpoints are a vital component of private networking within Amazon Web Services. They provide a secure, scalable way to connect directly to AWS services or supported third-party SaaS offerings—without traversing the public internet. This mechanism is particularly useful for organizations that demand enhanced data privacy, minimized attack surfaces, and low-latency access to critical services.

Understanding how interface endpoints function within a VPC is essential for building robust, high-security architectures in the cloud. These endpoints establish a private connection between your resources hosted in a VPC and other AWS services by creating elastic network interfaces (ENIs) within your subnet.

Detailed Steps in Configuring a VPC Interface Endpoint

Configuring a VPC interface endpoint begins with identifying the specific AWS service (or a privately shared endpoint) that your application needs to access. This could be a native service like Amazon S3 or DynamoDB, or a custom endpoint hosted by another AWS account using AWS PrivateLink.

Once the target service is selected, the next step is to instantiate the endpoint in a specific subnet within your VPC. AWS then automatically provisions an ENI—an elastic network interface—that acts as a virtual entry point to the designated service.

This ENI receives a private IP address, selected from the available address range of the chosen subnet. Importantly, this IP address is persistent, remaining unchanged unless the interface endpoint is explicitly deleted. This static IP behavior simplifies DNS configuration and enhances predictability in network routing.

Seamless Traffic Routing with Minimal Configuration

One of the key benefits of VPC interface endpoints is the elimination of the need to modify VPC route tables. Traditional route table changes often introduce operational overhead and configuration risk, especially in large-scale environments with multiple subnets and tightly controlled routing logic.

Instead, VPC interface endpoints reroute traffic directly through the associated ENI. The endpoint is resolved via private DNS, allowing your applications to interact with AWS services as though they were operating within the same local network—even though the requests are being transparently redirected through AWS’s backbone infrastructure.

This architecture results in a seamless and highly efficient method for maintaining secure service connectivity while preserving control over internal network behavior.

Support for Dual-Stack IP Configurations

As of May 2022, Amazon Web Services introduced enhanced support for both IPv4 and IPv6 address protocols on interface endpoints. This dual-stack capability significantly expands network compatibility and futureproofs architectures designed for global reach and scalability.

IPv6 support is particularly valuable for organizations aiming to maintain compliance with regional mandates or preparing for environments where IPv4 exhaustion is a constraint. By supporting both addressing schemes, AWS allows developers and network architects to build hybrid infrastructures that are resilient, modern, and capable of adapting to evolving internet standards.

Benefits of VPC Interface Endpoints in Secure Cloud Networking

The primary value proposition of using VPC interface endpoints lies in their ability to isolate traffic from the internet. In environments with stringent regulatory or compliance requirements—such as those in the finance, healthcare, or government sectors—this capability is indispensable.

Since the connection does not involve public IPs or traverse external gateways, there is minimal exposure to external threats or data interception. Network traffic remains encapsulated within the AWS backbone, a high-throughput and encrypted pathway that offers both security and performance advantages.

Moreover, organizations can combine VPC interface endpoints with security services such as AWS Identity and Access Management (IAM) policies, AWS PrivateLink, and security groups to enforce granular access control. This layered security posture ensures that only authorized resources within the VPC can interact with specified AWS services through the private interface.

Enhanced Resilience and Availability

Each interface endpoint supports multiple availability zones within a region, contributing to redundancy and high availability. In mission-critical applications where service continuity is paramount, this distributed architecture ensures that even if one availability zone experiences disruption, traffic can be rerouted through alternative zones without manual intervention.

Load balancing and failover capabilities are inherently supported, particularly when multiple subnets are utilized in conjunction with interface endpoints. This means developers can design applications that are fault-tolerant by default, minimizing downtime and optimizing user experience.

Integration with Hybrid Architectures and On-Premises Networks

VPC interface endpoints are not limited to purely cloud-native environments. In hybrid architectures—where workloads are spread between on-premises data centers and AWS—the use of interface endpoints plays a vital role in ensuring cohesive connectivity.

By integrating these endpoints with VPNs or AWS Direct Connect, enterprises can allow on-premises systems to securely interact with AWS services without requiring internet access. This helps maintain a unified security posture across the hybrid estate and minimizes the risk of data breaches through external exposure.

Additionally, organizations leveraging container orchestration platforms such as Amazon ECS or Amazon EKS can use interface endpoints to ensure that their containerized workloads have stable, secure access to AWS services like Amazon CloudWatch, Secrets Manager, or API Gateway.

Cost Considerations and Performance Optimization

While VPC interface endpoints provide unparalleled security and privacy, it’s important to consider the cost implications. AWS charges for interface endpoints based on hourly usage and data processed through the ENI. Therefore, strategic placement and usage policies can help optimize costs without compromising performance.

Architects should also evaluate the traffic patterns and access frequency when designing endpoint placement. Grouping dependent resources within a single subnet or AZ can reduce data transfer charges and improve latency.

Furthermore, combining interface endpoints with AWS service quotas and monitoring tools like CloudWatch Metrics enables better oversight and governance. These insights can be used to tune your architecture for both efficiency and budget compliance.

Comprehensive Insight into AWS Gateway Endpoints

Amazon Web Services (AWS) offers a versatile and secure cloud infrastructure that supports seamless interaction with its wide array of services. Among the many networking constructs AWS provides to ensure secure communication within the ecosystem, Gateway Endpoints hold a critical position. These endpoints are engineered specifically to enable private and cost-effective connectivity to certain AWS services without requiring traversal over the public internet.

The Core Functionality of Gateway Endpoints

A Gateway Endpoint serves as a conduit that allows traffic to flow directly between a Virtual Private Cloud (VPC) and specific AWS services, namely Amazon S3 and Amazon DynamoDB. Unlike conventional internet-based access patterns, Gateway Endpoints operate entirely within AWS’s internal network. This routing mechanism ensures that sensitive data never leaves the secured AWS environment, offering both operational efficiency and enhanced security.

Rather than generating a dedicated network interface within the VPC—like Interface Endpoints do—Gateway Endpoints utilize an alternative method based on route table configuration. A static entry is injected into the VPC’s route table, designating the target AWS service as a destination through the specified Gateway Endpoint. This indirect yet reliable approach simplifies network architecture while bolstering control.

Differentiating Between Gateway and Interface Endpoints

To fully grasp the uniqueness of Gateway Endpoints, it’s essential to contrast them with Interface Endpoints. The latter leverage AWS PrivateLink technology and provision elastic network interfaces within your VPC. These interfaces enable private connections to services powered by PrivateLink—including AWS-hosted services, third-party services, and custom applications.

Conversely, Gateway Endpoints function without introducing any network interface or consuming private IP addresses. Instead, they embed routing rules that direct data packets toward AWS services over the AWS global backbone. This streamlined design makes Gateway Endpoints less resource-intensive and easier to manage, especially for applications that require frequent access to S3 or DynamoDB.

Architectural Simplicity and Scalability

Gateway Endpoints are inherently scalable. They are not constrained by throughput limitations and can serve multiple subnets within a VPC. Since these endpoints use route table entries rather than physical or virtual interfaces, they scale with the size of your environment without requiring administrative overhead. For large enterprises running analytics pipelines or massive data lakes, Gateway Endpoints offer a seamless mechanism to ingest, process, and retrieve data from S3 without bottlenecks.

Furthermore, their stateless and passive nature contributes to their resilience. They don’t require patching or maintenance and operate independently of availability zone-specific infrastructure. This architectural model results in greater uptime and predictable network behavior across distributed applications.

Cost-Efficiency of Gateway Endpoints

One of the standout benefits of employing Gateway Endpoints is their cost-effectiveness. Unlike Interface Endpoints, which incur hourly charges and data processing fees, Gateway Endpoints come with no additional costs. There are no per-hour or per-GB data processing charges. For organizations that rely heavily on S3 for object storage or DynamoDB for NoSQL databases, this offers substantial long-term savings.

This economic advantage is especially pronounced in high-throughput environments such as video streaming platforms, big data analytics workloads, or backup architectures, where petabytes of data may be transferred frequently. Eliminating data egress charges for these workloads can significantly lower cloud expenditure.

Implementation and Configuration

Configuring a Gateway Endpoint involves minimal effort through either the AWS Management Console, AWS CLI, or infrastructure-as-code tools such as AWS CloudFormation or Terraform. The process begins with selecting the desired service (S3 or DynamoDB) and the VPC in which the endpoint will be deployed. Administrators then associate the endpoint with specific route tables and define policies to restrict or allow access.

The endpoint policy, a JSON-based access control document, governs what actions can be performed on the respective AWS service via the endpoint. For instance, you could restrict access to a specific S3 bucket or limit DynamoDB access to read-only operations. These policies add an extra layer of granular control that strengthens security posture without complicating the user experience.

Security Implications and Best Practices

Gateway Endpoints significantly improve the security profile of applications. By keeping all traffic within the AWS network, they eliminate exposure to external internet routes. This eliminates a wide range of attack vectors associated with internet access, including man-in-the-middle attacks, IP spoofing, and denial-of-service exploits.

To further reinforce security, AWS Identity and Access Management (IAM) roles and endpoint policies should be carefully designed to enforce least privilege access. Using fine-grained permissions ensures that only specific users, services, or resources can access S3 buckets or DynamoDB tables through the endpoint.

Network segmentation can also be implemented by associating different route tables with different subnets. This allows security architects to design access flows that comply with organizational boundaries, compliance requirements, or data governance protocols.

Integration with Hybrid Architectures

For enterprises adopting hybrid cloud strategies, Gateway Endpoints offer a convenient bridge between on-premises environments and AWS cloud services. When coupled with AWS Direct Connect or VPN tunnels, Gateway Endpoints allow secure access to AWS services from internal data centers without routing traffic over the internet. This enables compliance-sensitive industries such as healthcare, finance, and government to integrate cloud storage and databases into their legacy systems without violating data residency or security regulations.

For example, a health-tech provider managing electronic medical records can sync data securely to S3 using Gateway Endpoints, ensuring both performance and compliance with HIPAA standards.

Monitoring and Observability

To ensure performance and detect anomalies, AWS offers native observability tools that work seamlessly with Gateway Endpoints. By integrating with Amazon CloudWatch, users can monitor request metrics such as volume, success rates, and latency. AWS CloudTrail logs can capture API activity over the endpoint, offering an audit trail that is invaluable for forensic analysis or compliance audits.

These logs can be exported to a centralized S3 bucket, visualized using Amazon Athena or QuickSight, and even fed into machine learning models to detect suspicious activity. Incorporating these tools into your workflow fosters a culture of proactive observability, strengthening both operational integrity and security assurance.

Advanced Governance Through Access Policies in VPC Networks

In environments characterized by multiple AWS accounts or large-scale collaborative teams, effective governance becomes indispensable. Virtual Private Cloud (VPC) Gateway Endpoints offer robust mechanisms to enforce strict access policies, empowering organizations to maintain control over their internal data pipelines. Leveraging AWS Identity and Access Management (IAM), administrators can define rules that tightly restrict access to services like Amazon S3 or DynamoDB, according to a variety of parameters such as user roles, IP addresses, or specific VPC endpoints.

This precision facilitates the implementation of shared service frameworks, enabling multiple business divisions or departments to interface with centralized data lakes without jeopardizing overall security. By tailoring policies that only allow interactions from designated sources and enforcing the presence of encryption headers, enterprises can achieve granular compliance with industry standards such as GDPR, HIPAA, or internal governance frameworks.

Moreover, policy-based governance ensures that only approved users and services interact with key resources, greatly minimizing the possibility of unauthorized access. The enforcement of these policies within the AWS environment provides both flexibility and enhanced control, paving the way for secure collaboration across departments.

Tailored Policies for Secure Data Access

Organizations can formulate endpoint policies with unmatched specificity. For instance, consider a scenario where a business restricts access to a confidential S3 bucket. This can be done by permitting only calls that originate from a known VPC endpoint, coupled with specific encryption or metadata requirements. Such finely honed policies enforce not only identity checks but also data handling procedures in transit.

This strategic layering of control is critical in heavily regulated sectors such as finance, healthcare, or defense, where inadvertent data exposure can result in severe penalties or operational setbacks. These refined IAM policy conditions act as a bulwark against misconfiguration and unauthorized intrusion, ensuring only authenticated pathways are utilized for data ingress or egress.

Strategic Advantages of Gateway Endpoints

Gateway Endpoints in AWS facilitate private and scalable interactions between your VPC and services like S3 or DynamoDB. Unlike traditional internet-facing communications, gateway endpoints anchor these connections within the AWS backbone network. This not only avoids the public internet but also enhances throughput, lowers latency, and nullifies outbound data transfer fees associated with NAT gateways or VPNs.

The following sections explore key scenarios where gateway endpoints unlock operational advantages, improving both performance and security.

Optimizing Big Data Workflows

A common use case involves organizations operating data lakes on S3, integrated with services such as Amazon EMR, Athena, or AWS Glue. These tools perform compute-intensive analytics over vast datasets, often generating frequent read and write operations. By routing all traffic through gateway endpoints, companies reduce network jitter, eliminate bandwidth constraints, and secure data access within the AWS perimeter.

This configuration is particularly beneficial during high-volume analytics tasks such as machine learning model training, real-time behavior tracking, or business intelligence dashboarding.

Enhancing Resilience in Backup and Restore Operations

Secure and efficient data backup is vital for business continuity. Many enterprises employ backup software or managed services that interact extensively with Amazon S3 for uploading snapshots, retrieving archives, or performing incremental updates. By utilizing gateway endpoints, backup applications avoid the latency and unpredictability of public internet paths.

Additionally, using endpoints aligned with IAM policies ensures that only backup agents with the appropriate permissions and origin identifiers can access critical recovery datasets. This builds an additional layer of trustworthiness into your disaster recovery architecture.

Facilitating Secure Log and Metric Transmission

Cloud-native applications routinely generate logs, diagnostic messages, and performance metrics, which are frequently aggregated into centralized S3 buckets for monitoring and observability. Using gateway endpoints, these logs are transported securely, without ever being exposed to external networks.

The configuration becomes particularly essential when compliance or audit policies require that logs remain entirely within internal boundaries. Whether handling access logs, API call records, or container metrics, gateway endpoints serve as a trusted conduit for such sensitive telemetry data.

Improving Serverless Application Connectivity

Serverless paradigms such as AWS Lambda and Step Functions offer rapid scaling and reduced infrastructure management. However, when these functions must interact with storage or NoSQL databases like S3 or DynamoDB, ensuring secure, performant access is vital. Gateway endpoints act as dedicated routes, maintaining secure, low-latency connections that stay entirely within AWS infrastructure.

This internal routing significantly lowers risk from man-in-the-middle attacks or unauthorized API exposure. Additionally, it aligns with principles of least privilege and zero-trust security models, making serverless designs even more secure and compliant.

Real-Time Data Management for High-Velocity Applications

Retail, logistics, and ecommerce platforms often depend on real-time inventory systems powered by DynamoDB. These systems demand extremely low-latency updates and near-instantaneous synchronization across distributed regions. Gateway endpoints improve system responsiveness by minimizing data path overhead and avoiding congested public gateways.

This not only boosts user experience for customer-facing applications but also ensures that internal dashboards, inventory databases, and recommendation engines maintain accurate, timely data.

Architectural Considerations for Gateway Endpoint Implementation

When integrating gateway endpoints into your cloud infrastructure, careful planning ensures optimal outcomes. Engineers must attach the endpoint to appropriate route tables so that internal requests to S3 or DynamoDB are routed correctly. This requires adjusting subnet configurations and possibly modifying network access control lists (ACLs) and security group rules to prevent unintended exposure.

It’s also important to integrate IAM policies at both the endpoint and bucket/table levels. This dual-layered approach prevents bypassing access controls by directly querying resource ARNs, ensuring that all access traverses through verified endpoints.

For example, consider using the aws:SourceVpce condition key in IAM policies to explicitly allow access only through a known endpoint. When paired with required encryption headers and metadata constraints, such controls form a comprehensive barrier against misuse.

Monitoring and Auditing VPC Endpoint Usage

Visibility into endpoint usage is critical for operational oversight. AWS CloudTrail can be configured to log all access requests to resources through gateway endpoints. These logs can be processed using Athena or delivered to centralized monitoring platforms for further analysis.

AWS Config can also play a pivotal role by auditing compliance against expected endpoint configurations. For example, Config Rules can be written to detect buckets without endpoint-only access or to alert administrators if unauthorized changes occur to endpoint policies.

Such tools not only improve security observability but also contribute to meeting audit requirements in regulated environments.

Limitations and Considerations

While Gateway Endpoints are powerful, they are not a one-size-fits-all solution. Their utility is currently confined to Amazon S3 and DynamoDB. If your application needs private access to other AWS services or third-party integrations, Interface Endpoints using PrivateLink will be required.

Additionally, Gateway Endpoints operate on the routing level and do not allow per-subnet configurations beyond route table associations. This might introduce complexity in environments with overlapping or multi-tiered networking models. Therefore, architecture planning should carefully consider endpoint placement, route propagation, and policy enforcement.

Future Prospects and Evolving Trends

The use of Gateway Endpoints is expected to expand as AWS continues to emphasize security, compliance, and performance. Enhancements may include expanded service compatibility, support for custom routing logic, and tighter integration with VPC Lattice or service mesh constructs.

As more organizations migrate workloads to the cloud and deploy microservices architectures, the demand for secure, scalable, and cost-efficient networking solutions like Gateway Endpoints will likely grow. Their simplicity, economic advantage, and native integration with AWS tools position them as an indispensable component in modern cloud-native design.

Understanding the Functionality of Gateway Endpoints in AWS VPC

In Amazon Virtual Private Cloud (VPC), gateway endpoints are designed to provide secure and scalable connectivity between resources within your VPC and specific AWS services without the need for internet access, NAT devices, or VPNs. Gateway endpoints are currently limited to support only Amazon S3 and DynamoDB. They enhance security and optimize data throughput by keeping traffic entirely within the AWS network.

To configure a gateway endpoint, follow these steps:

• First, establish the endpoint for either S3 or DynamoDB based on your application needs.
• Associate the endpoint with relevant route tables in your VPC.
• AWS automatically updates the route tables to include a route that targets the endpoint for the appropriate IP prefix (for instance, the S3 IP range).
• Any EC2 instance or container within subnets linked to these route tables will begin to use the endpoint by default.

This method ensures an automatic and seamless routing mechanism. However, note that gateway endpoints are region-specific and currently support only IPv4. If you attempt to delete the route entry added by AWS, you must first remove the associated endpoint.

Key Contrasts Between Gateway Endpoints and Interface Endpoints

When planning a network design strategy in AWS, it’s crucial to distinguish between gateway and interface endpoints. Though both serve to connect private VPC environments to AWS services without traversing the public internet, their implementations and use cases differ greatly.

• Supported Services: Interface endpoints cater to a wide array of AWS services, third-party SaaS offerings, and marketplace integrations, while gateway endpoints are narrowly tailored to S3 and DynamoDB.
• Technical Architecture: Gateway endpoints function through route table manipulation, redirecting traffic to AWS services internally. Interface endpoints, in contrast, leverage Elastic Network Interfaces (ENIs), offering direct IP-based access.
• Cost Structure: Gateway endpoints incur no cost, making them highly economical. Interface endpoints, however, are priced based on hourly usage and data transfer volume.
• Protocol Compatibility: Interface endpoints are compatible with both IPv4 and IPv6, ensuring forward compatibility. Gateway endpoints presently support only IPv4.
• Recommended Scenarios: Interface endpoints are preferred for accessing APIs or services that require secure and granular control. Gateway endpoints are the optimal solution for storage-heavy workloads that require consistent interaction with S3 or DynamoDB.

Real-World Scenarios for Implementing VPC Endpoints

To appreciate the utility of AWS endpoints, let’s delve into practical deployment scenarios that demonstrate cost efficiency, enhanced security, and architectural clarity.

Scenario 1: Lowering Costs in ECS Workloads Using Interface Endpoints

In containerized environments such as Amazon ECS, tasks frequently pull images from Amazon ECR and communicate with external analytics platforms like Databricks. If the ECS tasks operate within private subnets, NAT gateways are traditionally used to provide outbound internet access, leading to substantial data transfer charges.

A more cost-efficient solution involves replacing NAT gateways with VPC interface endpoints. For example, businesses can deploy interface endpoints for ECR and Databricks connectors via AWS PrivateLink. This redirection ensures all traffic remains within the AWS fabric, eliminating unnecessary traversal through the internet and significantly reducing network latency and operational costs.

Even when deployed across multiple availability zones for redundancy, interface endpoints consistently outperform NAT gateways in terms of pricing structure and throughput reliability.

Scenario 2: Optimizing S3-Based Workflows via Gateway Endpoints

Imagine a data archival system that uses web crawlers running in EC2 instances within a private subnet. These crawlers are designed to scrape data from the internet and store it in Amazon S3. Without optimization, such systems often require a NAT gateway to upload data, inadvertently inflating AWS bills due to data egress.

Introducing a gateway endpoint specifically for S3 enables the crawlers to upload content directly, circumventing the need for a NAT device for internal AWS communication. This change slashes the bandwidth charges dramatically.

For outbound connections—like downloading content from external sources—the crawlers still leverage the NAT gateway. However, this architecture smartly segregates traffic, sending internal AWS traffic through the cost-free gateway endpoint and reserving the NAT gateway for external communications.

Scenario 3: Enabling Private SaaS Connectivity Using Interface Endpoints

In a software-as-a-service model, enterprises often require customers to access hosted applications in a secure and private manner. Interface endpoints, powered by AWS PrivateLink, enable this capability elegantly.

Here is how it works:

• Deploy EC2 instances hosting your SaaS product behind a Network Load Balancer (NLB).
• Register this load balancer as a PrivateLink endpoint service.
• Provide your customers the necessary permissions to create interface endpoints within their own VPCs that connect to your service.

This model ensures traffic remains confined to the AWS backbone, offering end-to-end security. Even customers operating in on-premises environments can securely access the SaaS application using AWS Direct Connect. The result is a high-fidelity, low-latency connection with enterprise-grade encryption and privacy.

Strategic Considerations When Choosing Between Endpoint Types

Selecting the appropriate endpoint type depends on your application requirements, architectural constraints, and budget considerations. Below is a strategic decision matrix to help guide your selection:

• Opt for Gateway Endpoints: If your VPC resources require regular access to S3 or DynamoDB and you’re aiming to minimize costs, gateway endpoints are the optimal route.
• Choose Interface Endpoints: When working with APIs, AWS services beyond S3 and DynamoDB, or integrating SaaS offerings, interface endpoints provide the needed flexibility, security, and scalability.

This bifurcation ensures that traffic is handled in a manner that aligns with both cost management and performance expectations.
