Best practices for working with the Apache Velocity Template Language in Amazon API Gateway
This post is written by Ben Freiberg, Senior Solutions Architect, and Markus Ziller, Senior Solutions Architect. One of the most common serverless patterns are APIs built with Amazon API Gateway and AWS Lambda. This approach is supported by many different frameworks across many languages. However, direct integration with AWS can enable customers to increase the […]
Propagating valid mTLS client certificate identity to downstream services using Amazon API Gateway
This blog written by Omkar Deshmane, Senior SA and Anton Aleksandrov, Principal SA, Serverless. This blog shows how to use Amazon API Gateway with a custom authorizer to process incoming requests, validate the mTLS client certificate, extract the client certificate subject, and propagate it to the downstream application in a base64 encoded HTTP header. This […]
Building resilient private APIs using Amazon API Gateway
This post written by Giedrius Praspaliauskas, Senior Solutions Architect, Serverless. Modern architectures meet recovery objectives (recovery time objective, RTO, and recovery point objective, RPO) by being resilient to routine and unexpected infrastructure disruptions. Depending on the recovery objectives and regulatory requirements, developers must choose the disaster recovery strategy. For more on disaster recovery strategies, see […]
Integrating Amazon API Gateway private endpoints with on-premises networks
This post was written by Ahmed ElHaw, Sr. Solutions Architect Using AWS Direct Connect or AWS Site-to-Site VPN, customers can establish a private virtual interface from their on-premises network directly to their Amazon Virtual Private Cloud (VPC). Hybrid networking enables customers to benefit from the scalability, elasticity, and ease of use of AWS services while […]
Getting started with serverless for developers: Part 3 – The front door
This blog post is part 3 of Getting started with serverless for developers, helping developers to start building serverless applications from their IDE. In the previous post, I introduce AWS Lambda and show how functions are designed to run business logic for serverless applications. In this blog post, you see how to access that business […]
Performing canary deployments for service integrations with Amazon API Gateway
This post authored by Dhiraj Thakur and Sameer Goel, Solutions Architects at AWS. When building serverless web applications, it is common to use AWS Lambda functions as the compute layer for business logic. To manage canary releases, it’s best practice to use Lambda deployment preferences. However, if you use Amazon API Gateway service integrations instead […]
Troubleshooting Amazon API Gateway with enhanced observability variables
Amazon API Gateway is often used for managing access to serverless applications. Additionally, it can help developers reduce code and increase security with features like AWS WAF integration and authorizers at the API level. Because more is handled by API Gateway, developers tell us they would like to see more data points on the individual […]
Building a serverless document scanner using Amazon Textract and AWS Amplify
This guide demonstrates creating and deploying a production ready document scanning application. It allows users to manage projects, upload images, and generate a PDF from detected text. The sample can be used as a template for building expense tracking applications, handling forms and legal documents, or for digitizing books and notes. The frontend application is […]
Building storage-first serverless applications with HTTP APIs service integrations
Over the last year, I have been talking about “storage first” serverless patterns. With these patterns, data is stored persistently before any business logic is applied. The advantage of this pattern is increased application resiliency. By persisting the data before processing, the original data is still available, if or when errors occur. Common pattern for […]
ICYMI: Season one of Sessions with SAM
February 12, 2024: Amazon Kinesis Data Firehose has been renamed to Amazon Data Firehose. Read the AWS What’s New post to learn more. Developers tell us they want to know how to easily build and manage their serverless applications. In 2017 AWS announced AWS Serverless Application Model (SAM) to help with just that. To help […]
