When the world wide web first emerged, integrating different types of operating systems was a core challenge. Hypertext transfer protocol (HTTP) created communication channels by sharing hypertext, these systems started speaking a common language over an accepted protocol, and the internet as we know today was born.
When creating a microservices architecture, the integration challenges are not very different: Multiple implementation technologies are physically separated by a network and need to communicate with each other. Microservices integration plays a vital role in creating a seamless experience of the system, from the end user’s perspective. Correctly integrated systems also help realize the benefits of distributed systems: They enable scaling at the service level and improve efficiency, and have a potential of reducing the infrastructure costs while serving business needs .
