We performed a comparison between OpenShift and VMware Tanzu Application Service based on real PeerSpot user reviews.
Find out in this report how the two PaaS Clouds solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable feature of OpenShift is the security context constraint (SCC). The solution’s security throughout the stack is good. And security context constraints provide port-level security. It's a granular level of control, where you can give privileges to certain users to work on certain applications."
"The initial setup is simple, and OpenShift is open-source, so it's easy to install on any cloud platform."
"Overall, the solution's security throughout the stack and software supply chain is excellent."
"What I like best about OpenShift is that it can reduce some of the costs of having multiple applications because you can just move them into small container applications. For example, applications don't need to run for twenty days, only to be used up by Monday. Through OpenShift, you can move some of the small applications into any cloud. I also find the design of OpenShift good."
"The most valuable feature is the high availability for the applications."
"This solution is providing a platform with OOTB features that are difficult to build from scratch."
"There is a quick deployment of the application, and we can scale out efficiently."
"OpenShift offers more stability than Kubernetes."
"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 solution is integrated very well with a lot of other systems. Also, its GUI is very good."
"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 valuable feature of the solution is the ability to check the flow of all the different variants within our applications."
"Its virtual upgrades are time-consuming."
"One glaring flaw is how OpenShift handles operators. Sometimes operators are forced to go into a particular namespace. When you do that, OpenShift creates an installation plan for everything in that namespace. These operators may be completely separate from each other and have nothing to do with each other, but now they are tied at the hip. You can't upgrade one without upgrading all of them. That's a huge mistake and highly problematic."
"One area for improvement is the documentation. They need to make it a little bit more user-friendly. Also, if you compare certain features and the installation process with Rancher, Rancher is simpler."
"One of the features that I've observed in Tanzu Mission Control is that I can manage multiple Kubernetes environments. For instance, one of my lines of business is using OpenShift OKD; another one wants to use Google Anthos, and somebody else wants to use VMware Tanzu. If I have to manage all these, Tanzu Mission Control is giving me the opportunity to completely manage all of my Kubernetes clusters, whereas, with OpenShift, I can only manage a particular area. I can't manage other Kubernetes clusters. I would like to have the option to manage all Kubernetes clusters with OpenShift."
"We need some kind of a multi-cluster management solution from the Red Hat site."
"The product’s integration with Windows containers and other third-party products needs improvement."
"OpenShift could be improved if it were more accessible for smaller budgets."
"The latest 4.0 version of OpenShift disabled a few of the features we previously made use of, although this wasn't a huge deal."
"The implementation is not easy, it is very complex and can take a day or two to complete."
"The solution is currently focused on VMware infrastructure and I would like to see more options made available."
"The solution's initial setup process was complex...The solution could benefit from improved customization and visibility for its users."
"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."
