Enhanced microservice security and advanced traffic management and good authentification

Pros

"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."

Cons

"Reducing the latency between the control plane and the data plane would be beneficial."

Helps to implement load balancing to distribute traffic across multiple service instances

Pros

"We can implement load balancing to distribute traffic across multiple service instances. Istio also offers traffic routing capabilities and circuit-breaking functionality. For security, it handles authentication using mutual TLS (mTLS) between services. It can authorize services using JWT tokens. Istio also allows defining policies for rate limiting to control traffic within services. "

Cons

"Based on my experience, the solution could be improved. They could simplify the learning process so that users can understand how its features work together, especially with components like Kibana. Learning about the different components is necessary. For instance, you need to understand the traffic flow, potential bottlenecks, and the architecture within Istio. "

Easy traffic management capabilities and good at making sure the containers are running

Pros

"Istio makes all that much easier - traffic splits, percentage traffic splits, doing some sort of chaos testing to see how it works."

Cons

"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
