Redentor Del Rosario

Sr. Solution Architect at Civatech Solutions

Leverage cloud security monitoring across multiple providers with robust integration

The best features Istio offers in my experience stand out because my job requires me to look for and use this type of tool, and this fits what I'm looking for, not just because it's free, not just because of the monitoring side, but simply because a lot of what pertains to my project is useful for Istio. One of the good things about the features is that due to the nature of the tool, it is really good for enterprise projects, and it can be helpful for every company. 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.

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."

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

"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 most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application."

"What I find particularly valuable about Istio is that it is free of cost."

"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."

"What I find particularly valuable about Istio is that it is free of cost."

More Istio pros

"The solution is cost-effective and has good adaptability."

Cons

"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."

"It would be good if the solution had more community forums."

"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."

"Istio's documentation is basic and would benefit from more examples."

"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."

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

"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."

More Istio cons

"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."
