Useful features, stable, easy to deploy, and works well
Its logging can be improved. When something goes wrong, it is not always very easy to find the problem. It is hard to identify whether the problem is because of low memory in the server or some configuration in Rational Build Forge. The error logs are not very detailed, and they should provide more information. It should also have more integration with third-party tools. It would be great to have more integration with third-party tools.

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

"I utilized the reporting features and a number of documents, as well as statuses."
"All features are useful; our customer doesn't have any complaints about the tool, and it works pretty well for what they want and what they need to do."
"Very good reporting features."
"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."
"The multi-tenancy with the VCD is great."
"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."
"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."
"Tanzu Mission Control has quite a set of rich features when compared to OpenShift."
"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 Tanzu platform is highly available, scalable, and flexible."
"The support from VMware is very good."
 

Cons

"The solution could be more user friendly."
"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem.

It would be great to have more integration with third-party tools."
"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem."
"Not user friendly for the layman."
"Addressing the high upfront costs could improve the product. Implementing a subscription-based model with tiered service options could make it more accessible to a broader range of customers."
"Tanzu is not yet a mature product, and it's not present in large environments."
"The biggest gap for me was just that the solution is relatively tied to Cloud Foundry. If you have anything you need to deploy outside of that, it becomes burdensome."
"The price is very high compared to other Kubernetes environments because Kubernetes is open source."
"Another area of improvement is pricing."
"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."
"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."
