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

"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."
"We use Istio for Service Discovery and routing traffic."
"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."
"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."
"What I find particularly valuable about Istio is that it is free of cost."
"VMware Tanzu Mission Control has many valuable features, such as ease of use and customization."
"We never experienced any problems with scalability."
"Defining security metrics has proven beneficial for customers in maintaining a safe environment."
"There are a lot of services available in VMware Tanzu Application Service, such as databases and application servers. You have everything you need in one application and you do not need to search outside of the solution."
"We feel very good about these features."
"Tanzu is easy to upgrade and scale, whether we're talking about horizontal or vertical scaling. It is as smooth as possible without any downtime. The platform maintenance, upgrading, and operations part is very smooth."
"The most important thing about the solution is its flexibility."
"The Tanzu platform is highly available, scalable, and flexible."
 

Cons

"Istio's documentation is basic and would benefit from more examples."
"Istio has issues with performance."
"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."
"It would be good if the solution had more community forums."
"Istio needs to be more mature and user-friendly."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"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."
"It is not easy to build a solution with containers. It has a graphical user interface, but you need to have a lot of knowledge of Linux and how to work in the command mode. Its support can also be improved. Currently, its biggest disadvantage is that it is a new product, and the clients prefer to go for a solution that has been in the market for a long time. There are not that many people who know this product."
"This product doesn't have a GUI. In order to use it properly, I need to connect it to a new GUI or build a GUI to manage it — it's pretty difficult."
"I would like to see additional support for things outside of Cloud Foundry."
"Having a unified dashboard to manage all infrastructure, whether it involves additional IT infrastructure or modern apps, would be highly advantageous"
"VMware Tanzu Service Mesh could add better integration with other cloud platforms, such as vRealize Automation or VMware vCloud Director for cloud providers."
"The infrastructure is quite challenging."
"One potential area for expansion would be leveraging AI capabilities, which my customer might be interested in exploring as they grow."
"The implementation is not easy, it is very complex and can take a day or two to complete."
 

Pricing and Cost Advice

"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."
"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."
"The solution is only for large or medium size enterprises because it is expensive."
"The least expensive licensing cost for VMware is around $350 per core."
"One of our Spanish customers told us that VMware Tanzu Service Mesh is a very expensive product for their data center."
"The solution is bundled in with Cloud Foundry so the pricing is not independent."
"I would recommend that businesses look into the full price for their requirements. The price is high, but there are some open-source add-ons that can be used for customization while keeping costs down, although these might not be suitable for everyone."
"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."
"There are different licenses available. You have to upgrade your license if you want to scale the solution more."
"The license for VMware Tanzu Application Service is expensive. The license should be cheaper."
