Concerns API Gateway handles

An API Gateway becomes one of the most important components in microservices architecture as it is the only place where core concerns are handled. Hence, a common implementation seen across all microservices implementation is introducing API Gateway which provides critical functionalities. Furthermore, API Gateway is the part which is connected to service discovery which maintains routes of all newly added services dynamically. In this section, we will look into gateway features and understand the role and impact of the overall architecture of our central operational layer.

Security

With an increase in distribution, there is a considerably high level of freedom. There are lots of moving services which may go up or down at any point in time. Considering from a security point of view, when there are a lot of moving parts, things can go considerably wrong. Hence, certain rules are needed which govern security. Therefore, we need to secure remote service invocations...
