Last article we already talked about the basic about service mesh. So now we’re going to discuss about Service Mesh: How Does It Work? A service mesh doesn’t have new functions or capabilities to an app’s run time environment. Apps in any design have always needed guidelines to specify how requests get from point A to point B. Service mesh takes the rationale guiding the service-to-service communication out of individual services and abstracts it to a layer of infrastructure.
To perform this, a service mesh is installed into an app as an array of network proxies.
1. As the request for the webpage went out, it was first received by the company’s web proxy.
2. After passing the proxy’s security measure, it was sent to the server that hosts the page.
3. Next, this page was returned to the proxy and again checked against its security measures.
4. And then it was finally sent from the proxy to user.
Service Mesh: How Does It Work
In service mesh, the instructions are transmitted between microservices straight to proxies in their own infrastructure layer. So the individual proxies that make up a service mesh are occasionally called sidecar considering they operate alongside each service instead within them.
The developers are less focused on business objective because without service mesh, each micoservice needs to be coded with logic to govern service-to-service communication. It also means communication breakdown are tougher to analyze because the logic that governs interservice communication is hidden within each service.
