It automatically takes care of every step from development to deployment, so you don’t have to worry about each step in the CICD pipeline to do things manually. So even as a beginner, you will feel very comfortable using OpenShift to execute a CICD pipeline for application deployment. In OpenShift, the deployment is performed using the DeploymentConfig command. One of the key components of OpenShift architecture is to manage containerized infrastructure in Kubernetes. Kubernetes is responsible for Deployment and Management of infrastructure.
- This course will teach you the basics of OpenShift container architecture and application deployment.
- Think of OpenShift as an operating system, images as applications that you run on them, and the containers as the actual running instances of those applications.
- Built around a core of Docker container packaging and Kubernetes container cluster management, OKD is augmented by application lifecycle management functionality and DevOps tooling.
- Payable versions of OpenShift come with dedicated support, although only within the version lifecycle.
- For deploymentconfig and many controllers — such as replication and namespace controllers — Kubernetes might be considered a more comprehensive option.
- We use Red Hat OpenStack, and we also use GlusterFS storage from Red Hat, which comes as a part of OpenStack.
As microservices architecture grew in popularity, so did the need for container orchestration at scale. Container orchestration is the problem that platforms like Kubernetes — a Google project released in June 2014 and eventually handed over to the Cloud Native Computing Foundation — and OpenShift help solve. Red Hat’s OpenShift Container Platform is Red Hat’s enterprise-grade security and support integrated with Kubernetes. Kubernetes is a platform for deploying, scaling, and managing — also known as orchestrating — container workloads on-premise and in the cloud. To perform all the cluster administration work, you need a suitable and easy-to-use web interface.
Container Orchestration through Kubernetes and OpenShift
OCS reduced that significantly, and containers are slightly quicker than VM servers, which positively affected our productivity. We have role-based access controls to tune and perform grant-level access to specific service accounts, roles and permissions. Practically, we have four clusters on-premises for each huge specific production grade system. Two of those clusters run several independent environments that are different from each other on the same clusters . No deployment sees another deployment, so they cannot interfere. It is an open-source development platform that enables developers to build and deploy their applications on cloud infrastructure.

Orchestration streamlines and automates many tasks an administrator or developer must otherwise do manually. These tasks include managing most aspects of resource utilization, including networking and storage, essentially any computing resource. The microservices architecture design pattern allows services to be developed, maintained, and scaled individually while communicating with other microservices via an API. With this application architecture, developers can create a microservice without dependencies on other microservices.
The scalability is the main reason why we use OpenShift. We heavily use automatic scalability because we use horizontal and vertical pod auto scalers. I found myself that the upgrading of OpenShift clusters is not a task that will successfully finish every time. In the beginning, it was very difficult to install OpenShift even by following the documentation. That installation was named UPI, which stands for user provision infrastructure. That means that you need to deploy your own load balancers to configure them correctly and enter your DNS and domains.
Advantages of Red Hat OpenShift:
The software is user-friendly and straightforward to use, which is favorable to a developer. The CodeReady Workspaces also reduce the time to market; a rival vendor released an offering we had to counter, so we used the platform to implement and deploy our counter in three to four days. The solution’s CodeReady Workspaces reduce project onboarding time in the region of 10-15%.
One of the benefits of OpenShift is that it can be deployed in the cloud, on-premise, or with a mixture of both. It allows for the usage of many resources, allowing developers and administrators to use the right resources for the right workload. RHCOS is a lightweight, container-optimized, and immutable base operating system. Red Hat acquired CoreOS in 2018 and has integrated it into OpenShift, the default supported host operating system on both the controller and worker nodes.

Let’s look at the benefits of Openshift container platform. However, there’s also an additional layer transforming Kubernetes into OpenShift. This blog looks at five major OpenShift benefits that you may not have heard about before. Find https://globalcloudteam.com/ out what they are, and how they can help your deployment. Kubernetes nodes can run on any Linux OS , while OpenShift nodes require Red Hat Enterprise Linux CoreOS. But offers additional features to simplify complex administrative tasks.
Unlike the earlier version of OpenShift V2, the new version of OpenShift V3 supports containerized infrastructure. In this model, Docker helps create lightweight Linux-based containers, and Kubernetes supports the task of orchestrating and managing containers on multiple hosts. Simplilearn can help you achieve this goal with their DevOps Certification Training course. Increasingly, companies are realizing the advantages these tools offer. According to a report released in 2021 by Redhat, 46% of companies surveyed saw container-based applications as the top software development priority for the next year. The OpenShift Console has developer and administrator oriented views.

There are a couple of restrictions in terms of managing clusters on a public cloud, but other than that, it has a lot of inbuilt components, which are helpful for managing the cluster better. OpenShift comes with a lot of marketplace operator-based solutions. It could also be a Helm Chart-based solution for deploying any cloud-native application or workload.
