Redentor Del Rosario - PeerSpot reviewer
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.

Provides a unique advantage by offering a global view for all workloads and clusters within the mesh but lack of a robust community for open-source support
There are a number of areas where Kong Kuma can improve. One is in terms of product delivery, such as Helm charts. There are a lot of gaps in the Helm charts currently. Another is in terms of the default monitoring and logging setup. It is not as production-ready as it could be. By default, Kuma comes with Loki, Yagger, and Prometheus to monitor the control plane and data plane, but the unified dashboarding and logging solution should be closer to production-grade. It is good for trying out the product, but I would not recommend taking it to production without setting up your own monitoring and logging solution. Additionally, Kuma recently released Fivecarless Mesh, which was built on top of Envoy. The challenge with this is that it adds overhead. If you want to run 100 containers in production, you will actually need to run 200 containers because you need to run one sidecar container per pod. Overall, I think Kong Kuma is a moderate product, but I would not personally recommend it for production use.

Quotes from Members

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

Pros

"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."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"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."
"What I find particularly valuable about Istio is that it is free of cost."
"The initial setup is pretty straightforward."
"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."
"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."
"It is a scalable product."
 

Cons

"Reducing the latency between the control plane and the data plane would be beneficial."
"Istio's documentation is basic and would benefit from more examples."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"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."
"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."
"Istio needs to be more mature and user-friendly."
"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."
"The initial setup is complicated. Although Kuma has its own CLI, CTL, and they say to use their CLI, if I have to build a generic solution, my personal preference would be to use Helm or another similar solution other than Kuma. If you have your own library CLI, it becomes hard for others to adopt it. For example, if I have to write some automation, infrastructure automation, I can't just use Kuma. I have to change my code to use Kuma's CTL, which is unfair because it doesn't make sense. It doesn't fit with my current automation structure. I have to do something extra, something additional, which I really don't like."
 

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."
"I have tried for my personal research and all those things. I have tried only the open-source version. So, for me, it was always free."
