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."
"Istio provides tremendous value, particularly in offering TLS and authentication over microservice-to-microservice communication."
"What I find particularly valuable about Istio is that it is free of cost."
"The initial setup is pretty straightforward."
"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."
"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."
"The most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application."
"The load balancing, service application, and monitoring of the life of the service are valuable features. We use it for authentication of call services, load balancing the calls among the service providers on service instances, and monitoring the health of the services."
"We use Istio for Service Discovery and routing traffic."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"If you're a beginner in infrastructure management and networking, learning Istio might pose some challenges. However, if you have some knowledge of networking or service meshes, you should find it manageable. Istio's website offers documentation to guide you through learning."
"If someone doesn't understand Kubernetes, they'll have issues working with Istio."
"It would be good if the solution had more community forums."
"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."
"Istio's documentation is basic and would benefit from more examples."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"Istio needs to be more mature and user-friendly."
 

Pricing and Cost Advice

"The tool is open-source."
"We use the tool's open-source version, so there are no hidden fees or additional costs associated with it."
"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."
