As we dive into the world of container orchestration, two names keep popping up: OpenShift and Tanzu. OpenShift is a popular choice among developers, with its robust features and scalability.
Tanzu, on the other hand, is a relatively new player in the market, but it's gaining traction quickly. In fact, it's built on top of Kubernetes, the same technology that powers OpenShift.
OpenShift offers a more comprehensive platform, with a wider range of tools and features. It's also more widely adopted, with a larger community of users and developers.
Tanzu, however, excels in its simplicity and ease of use. Its intuitive interface makes it a great choice for developers who are new to container orchestration.
Features
OpenShift and Tanzu both offer robust feature sets, but they differ in their approach to Kubernetes management.
OpenShift's core feature is its use of Kubernetes as its foundation, allowing it to leverage Kubernetes' features and benefits. It also offers a range of security features, including Container Security, Auditing, Certificates, Encrypting Data, and Vulnerability Scanning.
Tanzu, on the other hand, focuses on simplifying Kubernetes management with its Tanzu Application Platform, which provides an all-in-one platform for developing and deploying cloud-native applications on Kubernetes.
Here's a comparison of some key features:
Both OpenShift and Tanzu offer a range of features that cater to different needs and use cases. Ultimately, the choice between the two will depend on your specific requirements and preferences.
Features
OpenShift is built on top of Kubernetes, which means it leverages all the features and benefits of Kubernetes. One of the main features of OpenShift is its security features, which include container security, auditing, certificates, encrypting data, and vulnerability scanning.
OpenShift has a robust security feature set that helps protect applications and data. Container security is a key feature, which monitors the security of containers across multiple layers, including host, container, and orchestration levels. This helps identify potential security vulnerabilities and provides tools to fix them.
OpenShift also has a comprehensive auditing feature that logs all security-related events, making it easier to track and investigate suspicious activity. Certificates are used to authenticate and secure connections within the cluster, and users can replace default certificates with custom ones.
Encrypting data is another important security feature in OpenShift, which protects sensitive data stored in etcd. Vulnerability scanning is also available through Red Hat Quay Container Security Operator, which helps identify potential security risks.
OpenShift is highly extensible, with a wide range of tools and platforms that can be connected to it. This makes it easy to integrate with other software and systems, including cloud services, CI/CD tools, and storage systems.
Here are some examples of the many tools and platforms that can be connected to OpenShift:
- Cloud services: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP)
- Storage systems: NFS, GlusterFS, Ceph
- CI/CD tools: Jenkins, GitHub, GitLab
VMware Tanzu, on the other hand, offers a range of features and tools to manage Kubernetes clusters. Its key features include a platform for building and deploying cloud-native applications, a Kubernetes grid for managing clusters, and a build service for automating the build and deployment of applications.
Tanzu also offers a range of additional tools and features, including Tanzu Mission Control for managing clusters, Tanzu Supply Chain Insights for tracking and monitoring software supply chains, and Tanzu Security for Kubernetes for securing Kubernetes clusters.
When choosing an OpenShift alternative, there are several key features to consider. Here are some of the most important ones:
These are just a few examples of the many features and tools available in OpenShift and its alternatives. When choosing a solution, it's essential to consider your specific needs and requirements.
ตัวอย่าง Use Case
In a healthcare setting, VMware Tanzu can be used to provide fast and secure access to patient data through a web application on the Frontend Tanzu Kubernetes. This is achieved by using Kong API Gateway to control access.
Doctors can access patient data quickly and securely through a web application on the Frontend Tanzu Kubernetes, with access controlled by Kong API Gateway. This ensures that sensitive information is protected.
Patient data is stored safely in PostgreSQL DBaaS, allowing nurses to easily record patient information through a web application on the Frontend Tanzu Kubernetes. This streamlines the process and reduces errors.
Rapid access to medical images is also possible through a web application on the Frontend Tanzu Kubernetes, with images stored securely in S3 Object Storage. This is particularly useful for radiologists who need to quickly review images.
Developers can rapidly develop and deploy new microservices on the Backend Tanzu Kubernetes, using RabbitMQ as a Service to improve communication between microservices. This enables the creation of complex systems quickly and efficiently.
Tanzu Observability allows IT teams to track the performance and status of all HIS applications. This provides a clear picture of system health and enables proactive maintenance.
Logs from the HIS system can be stored and analyzed using VMware Tanzu Loggregator, providing valuable insights into system behavior. This helps IT teams identify and resolve issues more effectively.

Detailed Comparison Table
In this section, we'll dive into the details of OpenShift's provisioning and deployment capabilities.
OpenShift provides fully automated provisioning of clusters, which is a game-changer for developers and administrators alike. This means you can quickly and easily set up a multi-master and multi-etcd cluster environment with etcd nodes that form their own cluster or are deployed on the same node as the master.
The default HAProxy load balancer is used to create this environment, which is a reliable and efficient way to distribute traffic. Additionally, Kubernetes Cluster API is used to detect and correct failed nodes, ensuring your cluster remains stable and available.
OpenShift supports multiple masters and automated failover between masters, providing high availability and minimizing downtime. This is especially important for applications that require 24/7 uptime.
Here are some key deployment options to consider:
One thing to note is that OpenShift only works with Red Hat Enterprise Linux, so you'll need a RHEL subscription to use it. This may be a limitation for some users, but it's worth considering the benefits of using a supported and stable operating system.
In terms of monitoring and support, OpenShift provides some built-in integrations with Prometheus and Grafana, but it's not as robust as some other solutions. Traditional support ticketing is also used, which may not be ideal for everyone.
Overall, OpenShift provides a solid foundation for deploying and managing containerized applications, with a range of deployment options and features to suit different use cases.
