Anticipating events that can cause a disruption to your system’s service is critical to building highly available, reliable systems.  Hazard analysis gives you a method to identify such events.  Chaos engineering gives you a method to confirm that a system behaves as expected in adverse conditions.  By combining these methods, Vanguard is building reliability into […]

The objective of this post is to walk you through how to set up a completely serverless Jenkins environment on AWS Fargate using AWS Cloud Development Kit (AWS CDK). Jenkins is a popular open-source automation server that provides hundreds of plugins to support building, testing, deploying, and automation. Jenkins uses a controller-agent architecture in which […]

Security is a shared responsibility between AWS and the customer. When we use infrastructure as code (IaC) we want to describe workloads wholistically, and that includes the configuration of firewalls alongside the entrypoints to web applications. As we evolve the infrastructure that our application is built upon, we can adjust firewall rules in the same […]

This post demonstrates how AWS Cloud Development Kit (AWS CDK) Infrastructure as Code (IaC) constructs and AWS serverless technology can be used to build and deploy a RESTful Application Programming Interface (API) defined in the OpenAPI specification. This post uses an example API that describes  Widget resources and demonstrates how to use an AWS CDK […]
