OpenShift technology is a leading Kubernetes platform that delivers extraordinary services to the user. OpenShift Customers have shorter application development cycles to deliver better quality software. OpenShift Provides Security from Operating system to container and is a Red Hat software product for container-based software deployment. OpenShift is also a hybrid cloud application platform as a service.

Tekslates OpenShift course is based on Red Hat Enterprise and Red Hat OpenShift Container Platform. OpenShift integrates with the technologies like Docker and Kubernetes. After the completion of this course, you will be a master in these technologies.

OpenShift is a cloud development Platform as a Service (PaaS) hosted by Red Hat. Its an open source cloud-based user-friendly platform used to create, test, and run applications, and finally deploy them on cloud.

OpenShift is capable of managing applications written in different languages, such as Node.js, Ruby, Python, Perl, and Java. One of the key features of OpenShift is it is extensible, which helps the users support the application written in other languages.

OpenShift comes with various concepts of virtualization as its abstraction layer. The underlying concept behind OpenShift is based on virtualization.

Virtualization

In general, virtualization can be defined as the creation of a virtual system rather than physical or actual version of anything starting from system, storage, or an operating system. The main goal of virtualization is to make the IT infrastructure more scalable and reliable. The concept of virtualization has been in existence from decades and with the evolution of IT industry today, it can be applied to a wide range of layers starting from System level, Hardware level, to Server level virtualization.

How It Works

It can be described as a technology in which any application or operating system is abstracted from its actual physical layer. One key use of the virtualization technology is server virtualization, which uses a software called hypervisor to abstract the layer from the underlying hardware. The performance of an operating system running on virtualization is as good as when it is running on the physical hardware. However, the concept of virtualization is popular as most of the system and application running do not require the use of the underlying hardware.

Types of Virtualization

  • Application Virtualization In this method, the application is abstracted from the underlying operating system. This method is very useful in which the application can be run in isolation without being dependent on the operating system underneath.

  • Desktop Virtualization This method is used to reduce the workstation load in which one can access the desktop remotely, using a thin client at the desk. In this method, the desktops are mostly run in a datacenter. A classic example can be a Virtual Desktop Image (VDI) which is used in most of the organizations.

  • Data Virtualization It is a method of abstracting and getting away from traditional method of data and data management.

  • Server Virtualization In this method, server-related resources are virtualized which includes the physical server, process, and operating system. The software which enables this abstraction is often referred to as the hypervisor.

  • Storage Virtualization It is the process of pooling in multiple storage devices into a single storage device that is managed from a single central console.

  • Network Virtualization It is the method in which all available network resources are combined by splitting up the available bandwidth and channels, each of which is independent of each other.
