VMware Tanzu and OpenShift: A Complete Guide

VMware Tanzu vs OpenShift

VMware Tanzu vs OpenShift are two major PaaS providers that provide highly compatible cloud services to their customers.

Because of this, many people often find it difficult to choose between the two, but each has advantages and disadvantages that you should consider before deciding on one or the other.

This guide will give you information about VMware Tanzu vs OpenShift so you can decide which one best fits your needs.

What is OpenShift?

OpenShift is a cloud-based, continuous integration and continuous delivery (CI/CD) platform that enables containerized applications’ rapid development, deployment, and management.

It is built on top of Kubernetes and provides robust features for managing microservices deployments.

What is VMware Tanzu?

VMware Tanzu is a cloud-native platform that enables developers to build, run, and operate their applications on any cloud.

It is an open-source project that provides tools and services for building, running, and managing cloud-native applications. With Tanzu, you can develop cloud-native applications quickly and easily.

Key Features of VMware Tanzu vs OpenShift

Regarding cloud-native applications, two main platforms stand out: VMware Tanzu and OpenShift.

Both platforms have their own unique set of features that make them ideal for different use cases. Here is a quick guide to understanding the key differences between these two popular platforms.

OpenShift is an open-source platform built on Kubernetes and offers enterprise-grade features such as RBAC (Role Based Access Control) and the ability to integrate with LDAP (Lightweight Directory Access Protocol).

In addition, OpenShift supports multiple languages such as Java, Ruby, PHP, Python, and Go. If you are looking for enhanced security or integration with existing infrastructure, then OpenShift may be a better option.

VMware Tanzu is based on vSphere but provides enterprise-grade security through Trust Domain isolation which ensures that your data remains secure even if an attacker gains access to one host in your cluster.

The service also supports container orchestration through Photon OS – VMware’s lightweight Linux distribution optimized for running containers without Docker daemon in the VM. With all the benefits of both OpenShift and Tanzu, it can be hard to decide which platform will work best for your needs.

With either choice, you will get enterprise-grade security so look at other factors like language support when deciding between these two platforms.

Pricing and Support Options

VMware Tanzu and OpenShift have multiple pricing options, so you may pick the one that fits your requirements best and falls under your budget.

For small businesses, both offer a free tier that includes basic features and support. You can upgrade to a paid plan for more features and support. The difference is in the type of support.

With VMware Tanzu, this is done through an online community forum where users can ask questions, and other users will answer them (similar to Stack Overflow).

With OpenShift, you get unlimited phone and email access with technical experts that can solve your problems faster than other channels.

In addition, they provide 24x7x365 enterprise-level support, so customers know they are covered. If you are interested in this service, you will need to pay more per month.

Differences in Programmability

OpenShift is more programmable than VMware Tanzu. It uses Linux containers rather than virtual machines, making it more portable and easier to run on different platforms.

Additionally, OpenShift offers more control over how applications are deployed and configured. It means developers can more easily fine-tune their applications to meet their specific needs. However, this also means that OpenShift is less suitable for people who do not want to get into coding.

One other important difference between these two cloud providers relates to deployment time.

Suppose you deploy an application in OpenShift and make changes while running. In that case, your new changes will be live almost immediately, within minutes or seconds, depending on the size of your app.

However, with VMware Tanzu if you make any changes while the app is running, you have to wait until your app finishes before those changes take effect.

Differences in User Experience

There are a few key differences between the user experience of VMware Tanzu and OpenShift.

With Tanzu, you can use either the graphical user interface or the command line interface.

With OpenShift, you are stuck with using the command line interface. It is much more efficient for those who prefer this type of interaction but less for those who want a GUI.

In addition, to deploy an application on Tanzu, you must know how to do it beforehand since there is no built-in GUI for this process. On the other hand, on OpenShift, it is just as easy as clicking a button.

The installation process is also different: Tanzu requires that all installations be done from the command line; meanwhile, on OpenShift, all installs can be done through their GUI tooling.

One more thing to note about these two options is that Tanzu only provides support for Linux operating systems while OpenShift supports Windows, Mac OS X, and Linux.

So if you need support for a non-Linux OS, then OpenShift would be your best bet.

Differences in On-Premises/Cloud Deployment Options

OpenShift is a cloud-based platform (PaaS) developed by Red Hat. OpenShift is a managed service that runs on Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure.

VMware Tanzu is an on-premises PaaS that runs on top of vSphere. Both platforms can be used to deploy and manage containerized applications. It integrates with all standard tools in the industry, such as Jenkins, Chef, Puppet, Docker, Kubernetes, AWS Elastic Beanstalk, etc.

OpenShift has similar functionality in its user interface but relies on KUBERNETES for cluster management.

OpenShift provides GUI tools to set up development environments, making it easier for beginners.

VMware Tanzu has a command line-based setup which requires more understanding of Linux administration and how containers work under the hoods.

Differences in Security Options

Security is one of the most important considerations when choosing a cloud platform. VMware offers three security options: Basic, Standard, and Advanced:

Basic provides enhanced protection for infrastructure services by scanning incoming requests with intrusion detection rules before they reach virtual machines or other hosts, ensuring that all applications running on a given host have the same level of protection from intrusion attempts.

Standard offers intrusion prevention rules to protect against internal and external threats but only allows two levels (read-only or read/write) for each application deployment type.

Advanced adds IPsec for data encryption at rest and in transit over public networks and IDS rules for firewall protection against intrusions. While you get more security with advanced, it requires additional license purchase.

On the other hand, OpenShift has a single set of built-in controls to safeguard your cluster’s access controls and enforce the least privilege using SELinux policies. You can also enable SSL termination on your router nodes if desired.

Overall, the integration of Linux containers into enterprise development workflows makes them a better choice than VMware Tanzu, which relies solely on VMs.

Conclusion

When deciding between VMware Tanzu vs OpenShift, it depends on your specific needs and preferences.

If you need a cloud-based solution that is easy to set up and manage, then Tanzu is a good choice. However, if you are looking for more control and flexibility, then OpenShift is the better option.

Keep in mind that both solutions have their pros and cons, so be sure to do your research before making a final decision.
