If you’ve been in the software business for some time, you’ve probably noticed that creating software isn’t only about adding features. There are usually many different tasks involved. You have to test your system, fix bugs, and ensure it keeps working over its lifetime.

The growing popularity of serverless architectures has led to an increased need for solutions to the modern challenges of microservice observability—one of the most critical components for running high-performing, secure, and resilient serverless applications. Observability solutions have to break through the complexity of serverless systems, and with the right stack, observability enables not only fast and easy debugging of applications, but drives optimization and cost efficiency.

AWS re:Invent was back and BIG last week in Las Vegas. Approximately 50,000 AWS customers and partners got together in Las Vegas to learn, talk shop, and maybe attend a couple of parties here and there. Not only did Lumigo have a booth, but our own Saar Tochner, R&D Team Lead and AWS Community Builder gave a well-received talk on Lambda extensions.

“Testing your production environment” refers to the practice of running tests on production servers, using actual data from real users. Production testing doesn’t replace other methods like unit or integration testing. Instead, it extends them. Smoke testing is one approach that Lumigo has implemented to test our own production environments.
