JETTI DINESH REDDY - PeerSpot reviewer
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

"What I find particularly valuable about Istio is that it is free of cost."
"The most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application."
"The security feature with mutual TLS authentication, which is identity-based, and the traffic management using cloud load balancers are very valuable."
"Istio's best feature is that it's easy to use."
"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 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 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 solution is integrated very well with a lot of other systems. Also, its GUI is very good."
"The Day 2 operations support is the most vital feature"
"The Tanzu platform is highly available, scalable, and flexible."
"Tanzu Mission Control has quite a set of rich features when compared to OpenShift."
"I have multiple Kubernetes environments within my environment. TMC gives me a single pane view, which is good for managing everything."
"The most important thing about the solution is its flexibility."
"The most popular feature of VMware Tanzu Mission Control is its graphical user interface for describing network policies on the Service Mesh, which is highly integrable with other tools commonly used in supply chains such as security."
"The valuable feature I have found to be the management of Kubernetes clusters in a private cloud or public clouds, such as Azure or Google Cloud Platform."
 

Cons

"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."
"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."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"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."
"Istio has issues with performance."
"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"Cost is always a concern. Smaller companies might find the price a bigger issue."
"LYNX is a managed cluster solution that takes care of specific details within a cluster, such as sequences or services. I haven't seen this feature in Tanzu Mission Control."
"I would like to see additional support for things outside of Cloud Foundry."
"The infrastructure is quite challenging."
"Tanzu provides better manageability as compared to OCP, but when it comes to tagging it with other products, it's a bit rigid. If I have to bring in any new product or something out of the box from a different vendor, working with Tanzu becomes a little difficult. For example, if I want to use the F5 services, I have to add one more layer of Avi, but I don't want to do that. If I have a list of the products that I want to use, such as for firewall services, with Tanzu, I will have to go through another layer, which creates complexity."
"The solution could improve by having better integration with other solutions such as HPE."
"The network control and security policies must be improved."
 

Pricing and Cost Advice

"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."
"We use the tool's open-source version, so there are no hidden fees or additional costs associated with it."
"The least expensive licensing cost for VMware is around $350 per core."
"Its pricing is very competitive. We get around 70% or 75%, sometimes even 80%, discount on the product. I would rate it a four out of five in terms of pricing."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"It is not the most expensive option, and I believe the capabilities align well with the value it provides."
"The product is not expensive, but it is not cheap."
"The solution is only for large or medium size enterprises because it is expensive."
"The licensing cost is expensive."
