Why? The issue of updating dependencies in individual services remains a challenge and such a strategy still requires additional release cycles deployment of software with updated dependencies. What if we want to change the application's behavior add new functionality or an error is detected in the current version of a dependency? Well all we have to do is release a new version of the dependencies and with it update all services running in production. So we see that the above approach does not fully solve the problem and is far from ideal. The abovementioned DRY rule is only partially fulfilled. Even though we have eliminated code duplication by separating common code and enclosing it in a separate library we still incur the cost of updating the software.
Additionally if we use multiple programming languages to implement various services socalled polyglot microservices and cloud native orchestration systems e.g. Kubernetes we must duplicate the implementation of the libraries. Not the way. Service Mesh What if we Email Marketing List delegated the functionalities that are repeated in each service to the infrastructure layer gaining additional previously unattainable possibilities? This way we have reached the heart of the article this is where Service Mesh comes in handy. Read also Istio Service Mesh What is Service Mesh In the Service Mesh architecture we add additional blocks to the infrastructure layer. One of such blocks is the socalled sidecar proxy.
It is usually implemented in the form of a lightweight TCP proxy and importantly as a separate process is implemented with each microservice required for the business. From this point on the services no longer communicate directly but the network traffic outgoing from a given service is routed through the infrastructure through the adjacent proxy to the proxy of the target service and only the target proxy directs the incoming traffic to the target service as in the figure below.
