We had a Kubernetes cluster, and Istio managed all the security aspects we handled on the security layer. We were not writing that specific part in the code. The solution saved us time from writing complex code inside the code. Istio handled things like securing and the traffic management part.

Istio will make life easier if you are using Kubernetes. Kubernetes is an orchestration tool for DevOps for infrastructure as a service. In terms of routing the request from different parts, Istio service mesh will make your life easy. There are a lot of internal technical discussions we can do regarding how it helps and what all those important things are.

Overall, it will make your life easier for DevOps people if they are using Kubernetes. If you are deploying it end-to-end with you taking ownership of deploying the ports and Kubernetes, Istio will make it easy for you.

We are using the Istio framework as the service mesh for our microservices. We use it as a load balancer for the network traffic that is coming in. 

We have HTTP traffic that is coming into our service, and this traffic has to go to multiple other services. Typically, in microservice, you have a class of servers that need to talk to each other. There is a proxy server that talks to these servers on the mesh layer.

I primarily use Istio for connecting services and security.
