When managing cloud-native connectivity and communication, there is always a recurring question on which technology is preferred for handling how microservice-based applications interact with each other. That is; “Should I start with an API gateway or use a Service Mesh?”.

When we talk about both technologies, we refer to the end-user’s experience in achieving a successful API call within an environment. Ultimately, these technologies can be classified as two pages of the same book, except they differ in how they operate individually. It is essential to understand the underlying differences and similarities between both technologies in software communication.

In this article, you will learn about service discovery in microservices, and also discover when you should use a Service Mesh or API gateway.
