CRM Program Release Manager at Louis Stokes Cleveland VA Medical Center

Great reporting features and very functional

The solution could be more user friendly. Trying to train somebody on it can be difficult. If you're in this field, you kind of learn the tools, but trying to show a PM how to find report sheets to pull data was difficult. I had to show them how to write the queries and pull the data that they needed. It's not a layman's solution. If you're working with a programmer or with an architect, you won't have issues trying to relay how to utilize the tool. It was for those who cut the checks where there were problems enabling them to pull the data they required. I guess the answer is DevOps, but it depends on your environment. Just being able to sign into dashboards and get accurate results was my biggest thing with my PMs on my projects. They like charts and pie graphs, the ability to see things at a glance data where they could make decisions on the fly.

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

"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."

"I utilized the reporting features and a number of documents, as well as statuses."

"Very good reporting features."

"The multi-tenancy with the VCD is great."

"The most valuable feature of the solution is the ability to check the flow of all the different variants within our applications."

"The initial setup is easy."

"The most valuable feature of VMware Tanzu Mission Control is the management functionality of the cluster life cycle. Additionally, the solution integrates well with other vendors, such as Velero for backups and Sonobuoy for compliance. Additionally, it works well in multi-cluster environments."

"We feel very good about these features."

"Tazu is a developer-friendly and highly mature product."

"The most important thing about the solution is its flexibility."

"Defining security metrics has proven beneficial for customers in maintaining a safe environment."

Cons

"Not user friendly for the layman."

"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem."

"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 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."

"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."

"I would like to see additional support for things outside of Cloud Foundry."

"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."

"One potential area for expansion would be leveraging AI capabilities, which my customer might be interested in exploring as they grow."

"The disaster recovery feature could be improved to provide better tracking of issues. I would also like to see the introduction of a dashboard view, for even further integration of all the areas that Mission Control looks at."

"The network control and security policies must be improved."

"Tanzu could provide more granular control over whatever networking is being done on the containers. I would also like to see a slightly more detailed view of application-level tracing. I'm referring to the connections between different microservices. If they added a service-matching feature, that would be helpful for the customers to build or be more effective."

"Customers have noticed a considerable price increase after VMware's acquisition by Broadcom."
