As AWS Lambda has matured as a serverless platform, there are two key ways the service has evolved: New capabilities that extend the platform to support new use cases like Lambda Container support, Lambda URLs and attribute-based access control support. Performance enhancements that enable Lambda functions to be more responsive and cost-effective such as Tiered compilation, and Graviton2 support are just a few examples of the investments AWS made in this space.
We introduced Crosswalk for AWS three years ago as a library of components on top of the core AWS platform to make it easier to get from zero to production on AWS, easier to adopt AWS best practices by default, and easier to evolve your AWS infrastructure as your application needs mature. Since then, we’ve added many new capabilities, expanded the portfolio of libraries, and made these libraries available to all Pulumi languages.
In Pulumi’s engineering department, we often build and distribute tools as native binaries to avoid the need for additional dependencies on user machines. Most of these tools are written in Go, which has good support for building self-contained binaries that target modern operating systems. While other Pulumi-supported languages like Node.js, Python, and .NET require additional runtime dependencies, it’s possible to bundle dependencies with the program. In this article, we’ll show you how to do that for a Node.
As part of our hackathon near the end of last year, we decided to explore solutions to a common problem when people are using Pulumi for their systems. A question that’s been asked in a few different forms is how to resolve circular dependencies between resources in a Pulumi program. A simple example of this idea is a modern web application with a static front-end and an API, where the front-end needs to know the URL of the API to be able to call it and the API needs to know the source domain of the front-end to allow it access via CORS.
