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."
"The initial setup is pretty straightforward."
"Istio can save you time in terms of network troubleshooting."
"Istio makes all that much easier - traffic splits, percentage traffic splits, doing some sort of chaos testing to see how it works."
"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."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"Istio has positively impacted my organization by helping our architecture design and development, and we use this as a mesh, applying it for every single application and using those components, which is helping our company and our clients to do many different aspects for all the use of Istio."
"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."
"Istio provides tremendous value, particularly in offering TLS and authentication over microservice-to-microservice communication."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"It would be beneficial if Istio offered paid support options, similar to AWS's enterprise support, to quickly resolve issues that might affect production."
"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."
"Istio's documentation is basic and would benefit from more examples."
"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."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"It would be good if the solution had more community forums."
"Istio needs to be more mature and user-friendly."
"For our use case that we applied it to, there were graph queues and the calls that were coming in. There were the things that we couldn't apply at the time, but it kind of worked."
 

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."
