Here is a detailed summary of the video transcription in markdown format, broken down into sections for better readability:
Introduction
- The session covers how to scale and secure your API workloads using Amazon API Gateway, AWS Private Link, and AWS Load Balancers.
- The speakers are Higgy Park (Specialist Solutions Architect at AWS), Youf Robbie (Director for Application Networking at AWS), and Fabrio (Group Product Manager at Itaú Bank in Brazil).
- The session aims to provide best practices and patterns for building scalable and secure API workloads using these AWS services.
API Gateway Connectivity Options
- There are two main components: API clients (front-end) and API endpoints (back-end).
- Front-end clients can connect to API Gateway using public or private connectivity.
- Public connectivity uses the internet or a VPC Gateway.
- Private connectivity uses AWS PrivateLink and VPC Endpoints.
- Back-end API endpoints can also be public or private.
- Public APIs are accessible over the internet.
- Private APIs are accessible only through private connectivity, such as VPC Endpoints or Transit Gateway.
Backend Integration Patterns
- Option 1: Use a 1:1 relationship between a VPC Link and a backend API endpoint.
- Provides isolation and independent deployability, but limited scalability due to VPC Link quotas.
- Option 2: Use a single VPC Link with an NLB and port-based routing.
- Scales better by fanning out to multiple backend APIs, but requires managing the NLB configuration.
- Option 3: Use a single VPC Link with an ALB and path-based routing.
- Provides more flexibility and scalability by routing at the application layer (Layer 7).
Frontend Integration Patterns
- When using private API Gateway endpoints, the behavior depends on whether private DNS is enabled or disabled in the VPC.
- With private DNS enabled, you can use the standard API Gateway-provided hostname.
- With private DNS disabled, you can use the VPC Endpoint ID or a combination of the API ID and VPC ID in the hostname.
- Custom domain names can be used to access both public and private API Gateway endpoints within the same VPC.
Scalability and Security Considerations
- Be aware of service limits and quotas, such as the number of VPC Links, NLB targets, and ALB configurations.
- Implement security measures like VPC Endpoint policies, resource-based policies, and security groups to control access to your private API endpoints.
API Gateway Journey and Announcements
- API Gateway has been scaling to process over 100 trillion API events per year, requiring significant platform improvements.
- A new feature, Private Custom Domains, has been launched to simplify the management and security of private API endpoints.
- Integrates with Resource Access Manager for cross-account and cross-VPC sharing.
- Supports IPv6 connectivity and provides domain-level policies for improved governance.
Itaú Bank's API Platform
- Itaú Bank, a large financial institution in Brazil, has built an API platform to enable faster time-to-market, improve efficiency, enhance security, and deliver a better developer experience.
- The platform provides capabilities such as API design, development, validation, versioning, and publishing, all integrated with AWS services like API Gateway, PrivateLink, and Resource Access Manager.
- Itaú Bank has achieved significant benefits, including a 60% increase in API reuse, 34% reduction in development costs, and a 92% customer satisfaction score.
Conclusion
- The session provided a comprehensive overview of how to scale and secure API workloads using AWS services, with a focus on API Gateway, PrivateLink, and Load Balancers.
- Recommendations were given for various backend and frontend integration patterns, as well as scalability and security best practices.
- The journey of API Gateway and the new Private Custom Domains feature were discussed, along with a customer case study from Itaú Bank.
- Attendees were encouraged to explore additional resources and sessions to further their learning on AWS services for API management and modernization.
