JETTI DINESH REDDY - PeerSpot reviewer
Infra , DevSecOps & Automation Architect at Zuellig Pharma
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…

Cloud Infrastructure Engineer at Safaricom Ethiopia plc
Has supported container-based deployments and improved infrastructure visibility through monitoring tools
Aria Operations, formerly known as VMware vRealize Operations, has been renamed to vROps. We are currently using this for monitoring purposes. For orchestration, we are using VCD to automate Telco Cloud. VCD is an automation tool, and we are also using VMware Tanzu Platform for the Kubernetes environment, alongside TKG, Tanzu Kubernetes Grid. These are also other solutions for the Tanzu Kubernetes environment. For Telco Cloud, we are using it to automate our company's operations, which is for a telecom company. We are familiar with these products, especially vCenter, ESXi, VCD, vCF, and vROps. It is very easy to integrate applications when we deploy vCenter and ESXi since we can enable vSphere with Tanzu feature. We can build namespaces and provide application developers the platform to deploy their applications on pods within containerization. We can easily manage, pull results, and create containers efficiently, making it a simple way to handle applications. We provide namespace labels for application developers, and we can manage their resources along with other aspects easily. Regarding security, we use many tools such as CDX and LDAP, AD for integrating our Kubernetes cluster with the developer teams. We can manage roles and permissions simply. It is very straightforward to integrate with EDX and other third-party tools, Active Directory, to the Kubernetes cluster, allowing easy access and management.

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."
"We use Istio for Service Discovery and routing traffic."
"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."
"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 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 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 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."
"We feel very good about these features."
"We never experienced any problems with scalability."
"The most valuable feature of the solution is the ability to check the flow of all the different variants within our applications."
"The Day 2 operations support is the most vital feature"
"The observability platform and end-to-end service portal provided by Tanzu are the most valuable features."
"A feature we find valuable is that other products can also be integrated with Mission Control. This means that we can see the status of specific clusters, as well as view the monitoring application logs all from one point."
"Tazu is a developer-friendly and highly mature product."
"The support from VMware is very good."
 

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."
"Handling large-scale environments with proxies can strain resources, but horizontal scaling can improve fault tolerance."
"Istio needs to be more mature and user-friendly."
"It would be good if the solution had more community forums."
"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 would be beneficial if Istio offered paid support options, similar to AWS's enterprise support, to quickly resolve issues that might affect production."
"I've seen applications where they had such strict time constraints, they couldn't use Istio because it was too much overhead."
"Istio has issues with performance."
"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."
"Tanzu could provide more granular control over whatever networking is being done on the containers."
"Customers have noticed a considerable price increase after VMware's acquisition by Broadcom."
"The product should support integration with Google Cloud Platform (GCP)"
"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"The price is very high compared to other Kubernetes environments because Kubernetes is open source."
"The network control and security policies must be improved."
"The cost is a major factor in this solution; anything above the standard version comes at a high price."
 

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."
"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."
"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."
"The license for VMware Tanzu Application Service is expensive. The license should be cheaper."
"The licensing cost is expensive."
"The solution is only for large or medium size enterprises because it is expensive."
"VMware Tanzu Mission Control is cheaper than Red Hat OpenShift."
