The issues with microservice API gateways

We have listed several key benefits and contributions of API gateways toward microservice-centric business applications. However, there are a few drawbacks too. As we all know, this gateway infrastructure is an additional abstraction layer, so all the control and the data flows happen via this middleware solution; therefore, there is the possibility of system performance degradation. This introduces an additional hub through which service requests and responses pass. Not only is it a single point of contact but also a single point of failure. When the number of microservices goes up significantly, complications will increase steadily. Service-to-service communication resiliency is not provided by API gateways. There are service mesh solutions, which guarantee the much-needed service resiliency that, in turn, results in reliable applications...
