For almost five years, we have been researching cloud-native applications. As part of an industry-wide push to cloud-native computing, a lot of stacks and middleware components are proposed every day, but few tools and processes help improving the applications themselves especially in terms of quality attributes such as discoverability, elasticity and resilience. With Helm charts, there is already a higher-level approach to package cloud applications in Kubernetes environments. Our work on static analysis of Helm charts and quality assessment beyond is documented and ongoing. In this post, we take a first look at CNAB, or Cloud Native Application Bundle which is self-described as secure and cloud-agnostic way to deliver applications.
