A simple solution that works as a proxy server and load balancer
I used the solution to build a project's proxy server and load balancer I found Envoy simple to use compared to alternatives like Traefik. The tool needs to incorporate better documentation and more example samples.  I haven't contacted the tool's support team.  I chose Envoy for the POC…

Enhanced microservice security and advanced traffic management and good authentification
When our developers are building the microservices, instead of imposing additional burdens or additional thinking on them, especially as part of network features such as traffic management, security, or observability, we deploy something from the infrastructure side, so developers need only focus…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I found Envoy simple to use compared to alternatives like Traefik."
"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."
"We moved them to the Istio framework and in this particular project we started from scratch, and we are happy with the amount of effort it has saved."
"Istio provides tremendous value, particularly in offering TLS and authentication over microservice-to-microservice communication."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"What I find particularly valuable about Istio is that it is free of cost."
"The tool's mutual TLS stands out. It provides secure communication between services within the cluster. Additionally, Istio offers built-in telemetry and tracing with tools like Jaeger, which aids monitoring and troubleshooting."
"We use Istio for Service Discovery and routing traffic."
"Istio's best feature is that it's easy to use."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"It would be good if the solution had more community forums."
"Istio has issues with performance."
"If someone doesn't understand Kubernetes, they'll have issues working with Istio."
"Istio's documentation is basic and would benefit from more examples."
"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."
"Reducing the latency between the control plane and the data plane would be beneficial."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"It would be beneficial if Istio offered paid support options, similar to AWS's enterprise support, to quickly resolve issues that might affect production."
 

Pricing and Cost Advice

"The tool is open-source."
"It is on the less expensive side. It provides a significant saving for us in terms of cost and other things. It is open-source. We just download it from the open-source framework and use it."
"You can deploy Istio free of cost and don't need to pay for it."
"We use the tool's open-source version, so there are no hidden fees or additional costs associated with it."
