Choosing the right solution for AWS Lambda external parameters
This post is written by Thomas Moore, Solutions Architect, Serverless. When using AWS Lambda to build serverless applications, customers often need to retrieve parameters from an external source at runtime. This allows you to share parameter values across multiple functions or microservices, providing a single source of truth for updates. A common example is retrieving […]
Running cross-account workflows with AWS Step Functions and Amazon API Gateway
This blog post provides a step-by-step guide on securely invoking a cross-account Step Functions workflow from a central account using API Gateway as front end. This pattern can be extended to scale workflow executions across different Regions and accounts.
Implementing mutual TLS for Java-based AWS Lambda functions
This post is written by Dhiraj Mahapatro, Senior Specialist SA, Serverless and Christian Mueller, Principal Solutions Architect Modern secure applications establish network connections to other services through HTTPS. This ensures that the application connects to the right party and encrypts the data before sending it over the network. You might not want unauthenticated users to […]
Building serverless multi-Region WebSocket APIs
This blog post shows how to use the AWS serverless platform to build a multi-regional chat application over WebSockets. With the cross-Region event routing of EventBridge the architecture is resilient as well as extensible.
Composing AWS Step Functions to abstract polling of asynchronous services
This blog post describes how to compose a nested Step Functions workflow, which asynchronously manages a custom service using the polling mechanism.
Building a serverless image catalog with AWS Step Functions Workflow Studio
This blog post demonstrates how to implement a serverless image cataloging pipeline using Step Functions Workflow Studio. By orchestrating AWS API actions and flow states via drag and drop, you can process user-generated images. This example checks images for appropriateness and generates tags based on their content without custom application code.
Migrating a monolithic .NET REST API to AWS Lambda
This blog post shows the required considerations for migrating a .NET Core REST API to AWS Lambda. You can now start to look at your existing code base and make an informed decision whether Lambda is for you. With the right abstractions and configuration, you can migrate a .NET Core API to Lambda compute with copy and paste.
Capturing client events using Amazon API Gateway and Amazon EventBridge
This post shows how to send client events to an API and EventBridge to enable new customer experiences. The example covers enabling new experiences by creating a way for software clients to send events with minimal custom code.
Mocking service integrations with AWS Step Functions Local
This post is written by Sam Dengler, Principal Specialist Solutions Architect, and Dhiraj Mahapatro, Senior Specialist Solutions Architect. AWS Step Functions now supports over 200 AWS Service integrations via AWS SDK Integration. Developers want to build and test control flow logic for workflows using branching logic, error handling, and retries. This allows for precise workflow execution with deterministic […]
Using the circuit breaker pattern with AWS Step Functions and Amazon DynamoDB
This post is written by Anitha Deenadayalan, Developer Specialist SA, DevAx Modern applications use microservices as an architectural and organizational approach to software development, where the application comprises small independent services that communicate over well-defined APIs. When multiple microservices collaborate to handle requests, one or more services may become unavailable or exhibit a high latency. […]
