Fernando Silva - PeerSpot reviewer
Ingeniero at Servicios Eyenet S.A De C.V
A cost-effective and fully integrated service mesh that has good adaptability
The initial setup for NGINX Service-Mesh is straightforward. I have twenty engineers specifically for SI deployments, and we rely on gnet environments. Typically, we have many users, maybe a thousand users, and in Mexico, working with EC Telecom, we serve around five million users for the ISP solution, including internet and service provider solutions.

Quotes from Members

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

Pros

"Istio's best feature is that it's easy to use."
"What I find particularly valuable about Istio is that it is free of cost."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"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 most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application."
"We use Istio for Service Discovery and routing traffic."
"Istio provides tremendous value, particularly in offering TLS and authentication over microservice-to-microservice communication."
"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 solution is cost-effective and has good adaptability."
 

Cons

"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."
"Reducing the latency between the control plane and the data plane would be beneficial."
"It would be good if the solution had more community forums."
"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."
"If someone doesn't understand Kubernetes, they'll have issues working with Istio."
"Istio needs to be more mature and user-friendly."
"Istio has issues with performance."
"NGINX Service Mesh could be improved by integrating more intelligence and stability through certifications and SSL certificates."
 

Pricing and Cost Advice

"You can deploy Istio free of cost and don't need to pay for 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."
"We use the tool's open-source version, so there are no hidden fees or additional costs associated with it."
"The pricing for NGINX Service-Mesh is very reasonable, offering us scalability and cost-effectiveness."
