The following are the terms and tools within the overall principles described above that successful DevOps engineers need to know
The term "virtualization" can be used on many aspects of computers. This is the process of creating a virtual environment that includes hardware platforms, storage devices, operating systems, network resources, and more.
Virtualization is the ability to share a single instance of a physical application or resource across multiple organizations or users. This approach is accomplished by logically assigning names to all of these physical resources and providing pointers to those physical resources as needed.
With your existing operating system and hardware, you can usually create virtual machines to run other operating s ystems and applications. This is called hardware virtualization. Virtual machines provide a unique environment that is logically different from the underlying hardware. Here, the system or machine is the host and the virtual machine is the client. This virtual environment is managed by firmware called a hypervisor.
There are several ways to virtualize the cloud servers.
• Grid Approach
• OS -Level Virtualization
• Hypervisor-based Virtualization
In hypervisor virtualization, there are several sub-methods that can be used to run multiple applications and other workloads on a single physical host. One way is to allow virtual machines to move between hosts without shutting down. This method is called Live Migration. Another technique is to actively load balance between multiple hosts in order to effectively utilize the resources available to the virtual machine. This concept is called distributed resource scheduling or dynamic resource scheduling.
Types of Virtualization
Cloud virtualization can be divided into four different types based on its characteristics.
Virtualization Mechanism in the Cloud:
Virtualization plays an important role in cloud technology and its working mechanism. Much of what happens in the cloud-users can share data in the cloud like an app, but they can also share virtualization and infrastructure. Virtualization is primarily used to deliver standard versions of applications to cloud customers. By releasing the latest version of the app, providers can effectively deliver the app to the cloud and its users, and virtualization is yours. By using this virtualization concept, all servers and software of other cloud service providers require third party maintenance on these servers and software payments monthly or annually.
Virtualization vs Cloud
Cloud technology requires the concept of virtualization, but there are differences between the two terms. Virtualization is a technology. You can think of it as software that can operate hardware. Cloud computing is a service that is the result of an operation.
Virtualization is a fundamental element of cloud computing, and cloud technology provides shared resources over the Internet as an on demand service.
Advantages of Virtualization
Reduce the number of servers using the concept of virtualization -
Improve technical skills
Business continuity has also been improved through the use of virtualization
It creates a hybrid virtual environment
Improve the efficiency of development and test environments
Lower total cost of ownership (TCO)
