TestJS Summit

TestJS Summit - January, 2021

The scariest thing about serverless is the fear of vendor lock-in and losing control. Planning, good architecture, and deployment procedures help keep switching costs reasonable. Hexagonal architecture is a useful approach for writing testable serverless apps. Integration testing is crucial for serverless apps, and hexagonal architecture helps fight vendor lock-in and reduce switching costs. Docker is used for testing serverless functions, and the practicality of hexagonal architecture remains a question.

<p>According to many polls, testing serverless applications and fear of the cloud vendor lock-in are among the top five challenges organizations face when adopting serverless. We often hear that using serverless effectively requires a mind shift. But what does that mean? Do we need new tools and strategies for testing serverless applications, or can we use existing tools we already use for our non-serverless applications? And what about cloud vendor lock-in? Is that a real thing or just a fictional story that scares people away from serverless? Can we decrease a risk of vendor lock-in using a well-known architecture, such as hexagonal architecture?</p><p>  <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a></p>
