The Serverless Application Repository by Amazon Web Services (AWS SAR) is, in simplified terms, a marketplace for Lambda functions. You can speed up application development by building on the functions (or function compositions) provided by it, and you can share your own functions with other cloud application developers. AWS SAR was launched over a year ago. In the Service Prototyping Lab at Zurich University of Applied Sciences, we are investigating better ways of building applications for cloud and post-cloud environments. Consequently, we did a full year observation of AWS SAR to find out what’s in it and what’s going on. Read on for some interesting excerpts and findings and for accessing the study document.
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.
In our research group, we have for many years observed and systematically explored how cloud applications are being developed. In particular, we focus our investigations on cloud-native applications whose properties are largely determined by exploiting the capabilities of modern cloud platforms for both their development and operation. As we are involved in European research on testing cloud applications (Elastest), our aim was to look at the current project results through the cloud-native glasses. This blog post reports about end-to-end testing of composite containerised applications from this perspective.
In recent months, we have extensively studied Helm charts, including setting up a continuous quality assessment, to find out more about this promising packaging format for Kubernetes applications. Apart from individual tweets and occasional talks, there was a lack of a coherent presentation of the ongoing work. Yet, due to the increasing installation base of Kubernetes stacks, the significance of this work appears to be on the rise. This blog post therefore tells what we achieved already and what we are still going to do in the next months.
