Microservices provide great benefits to development organizations. They enable multiple autonomous development teams to work on the same application, maintaining efficiency,speed, and utilization of modern resources such as open source, containers and programming languages. The Microservice paradigm simplifies application building,debugging, management, deployment, scalability and of course time to market.

While the move to microservices-based architecture is relatively new, it is already mainstream. A majority of companies are choosing it as their default architecture for new development,and you are not cool if you are not using microservices. With regards to migrating legacy apps and breaking them down to microservices, companies are showing more conservatism, and rightly so.

Alice keeps all her passwords in an Excel file on her desktop. However, she was told it is a very bad practice, since Eve can easily get access to the computer, read the file,and access Alice passwords and accounts. To enhance her security, Alice got a password protection software, KeePass, and she now saves all her passwords safely there – except for her KeePass password, which Alice keeps in an Excel file on her desktop. ‍Good news for Eve...

The backend developer team at Detectify has been working with Go for some years now, and it’s the language chosen by us to power our microservices. We think Go is a fantastic language and it has proven to perform very well for our operations. It comes with a great tool-set, such as the tool we’ll touch on later on called pprof. However, even though Go performs very well, we noticed one of our microservices had a behavior very similar to that of a memory leak.

Microservice architectures running on containers have made applications easier to scale and faster to develop. As a result, enterprises are able to innovate faster and accelerate time-to-market for new features. To make management of microservices even more efficient and easier to run, service mesh solutions like Istio, Envoy, and Linkerd – and now AWS App Mesh – have become the next core building blocks of microservices infrastructure built on containers.
