Is Cloud Computing Virtualization?
The best way to explain the difference between cloud computing and virtualization is to say that the former is a service, while the latter is a technology. Cloud computing and virtualization are two terms that often seem compatible. Although the two technologies seem to be similar they are not the same thing. Their difference can significantly affect your business decisions.
Cloud computing is the delivery mode of service by using shared computing resources, data or software through the internet. Cloud computing technology is based on three factors- grid computing, utility computing, and automatic computing. Cloud Computing is the hosting and delivery methods used to provide software. Cloud computing, on the other hand, is a specific kind of IT setup that involves multiple computers or hardware pieces sending data through a wireless or IP-connected network. In most cases, cloud computing environments involve sending inputted data to remote locations through a somewhat abstract network trajectory known as “the cloud”. All the data is stored on the servers and can be accessed simply by authenticating with the help of the internet anywhere in the world. Apple, Amazon, Google, Microsoft, etc. are the biggest cloud service providers provide very large storage to its users and making the work easier.
Virtualization is the creation of a virtual (rather than actual) version of something, such as a server, a desktop, a storage device, an operating system or network resources. It is the process of creating a virtual version of something like computer hardware. A Virtual machine provides an environment that is logically separated from the underlying hardware.Virtualization is technology that separates functions from hardware, while clouds rely on that split. Virtualization is the platform for cloud computing or virtualization is the base for cloud computing. Virtualization is the fundamental technology that directs for cloud computing.
Virtualization separates the compute framework from physical environments. Virtualization helps you to run different operating systems and applications on the same system. Virtualization is technology that allows you to create multiple simulated environments or dedicated resources from a single, physical hardware system. Through virtualization, we plan for server consolidation through which we maintain multiple servers with different functionality. Server virtualization allows you to split the resources for balancing loads of a single server for multiple purposes. Virtualization software lets you divvy up the resources of a single physical server to create several separate virtual environments.
Can Cloud Computing replace Virtualization?
Virtualization plays a very important role in cloud computing technology. Virtualization changes the hardware-software relations. Virtualization is one of the fundamental elements of Cloud Computing. Cloud Computing and Virtualisation work together to provide different offerings. Virtualization help cloud computing technology to utilize the full capabilities of cloud computing. Cloud offers virtualization product as a part of their services. The difference is that a true cloud provides the self-service feature, elasticity, automated management, scalability, and pay-as-you-go service that is not inherent to the technology. Virtualization is the product of a cloud. No, Cloud Computing is not going to replace virtualization.
Difference between Cloud Computing and Virtualization:
- Virtualization is software that requires dedicated hardware’s for multiple virtual machines while cloud computing refers to a service that results from that manipulation.
- Virtualization is a primary element of cloud computing and it helps deliver on the value of cloud computing.
- Virtualization limits the scalability of Virtual Machine configuration while Cloud computing can be extended as per your wish.
- Virtualization is a Software as a Service while Cloud Computing is an Infrastructure as a Service.
- Virtualization offers you to install multiple operating systems on a single server or a computer while Cloud Computing offers a large number of the user to access the network through the same link.
- Virtualization doesn’t depend upon cloud computing, while we need virtualization for cloud computing.
- Virtualization is Image-based while Cloud Computing is Template bases.
Types of Virtualization:
Hardware Virtualization is the state in which virtual machine software is directly installed on the hardware. It is used for server platforms to control virtual machines. You can use different OS and application on top of hardware virtualization.
Server Virtualization is the state in which virtual machine software is directly installed on the server. It is used in server balancing to balance the load.
Operating System Virtualization:
Operating System Virtualization is the state in which the operating system is installed on the host operating system. It is used for testing applications on different platforms of the operating system.
Storage Virtualization is the state in which grouping of physical storage is done for multiple network storage devices to maintain a single storage device. It is mainly used for backup and recovery purposes.
Types of Cloud:
Below are the different types of cloud on deployment mode:
A private cloud means using a cloud infrastructure solely by one customer or organisation. Security level is highest while using the private cloud. This version of the cloud is controlled by certain people only.
Public cloud means using a cloud infrastructure on the premises of cloud computing only. the customer does not have physical control over the infrastructure. Security level is at risk while using the public cloud.
Hybrid cloud means you can use both services private and public depending upon purposes. You can use customer login in public cloud and safeguard important data in the private cloud.
Community cloud refers to share infrastructure between organisations to share data and data management concerns.
Conclusion – Is Cloud Computing Virtualization:
Virtualization lets you easily outsource your hardware and eliminate any energy costs associated with its operation. Keeping in mind virtualization is technology while cloud computing as a Service,
Cloud can be used in the public domain as a service provider while virtualization can be used by IT companies for cost-efficient data center setup. If you do most of your work on a Mac but use select applications that are exclusive to PCs, you can run Windows on a virtual machine to get access to those applications without having to switch computers. You can select between Virtualisation and Cloud computing based on your purpose.
