What Are The Different Types Of Virtualizations In Cloud Computing?

The term “Virtualization” means to create something virtually. This might include virtual hardware platforms, computer networks, and storage devices. There are various types of virtualizations that can be used for different purposes. Virtualization ages back to the 1960s, but has become very popular in the recent decade. Moving on to the different types of virtualizations in cloud computing.

Types Of Virtualizations In Cloud Computing

1. Network Virtualization

Network Virtualization can be simply referred to as the system where multiple networks can visually run at the same time. And all these multiple networks have a private data plan and control system. On the same physical network, multiple networks co-exist. But these have a separate functioning system. Network Virtualization does not compromise the security factor. Network Virtualization enables the user to keep track of all the actions that happen on the network. Data usage can be easily identified and the network can be monitored constantly.  

Network Virtualization is very safe and reliable and the issue of one network cannot cause a major impact on the other network, present on the same physical network. Productivity and efficiency are the two main focuses of Network Virtualization. There two types of Network Virtualization, they are internal and external Network Virtualization.

  • Internal Network Virtualization: Increase network functionality onto a single system.
  • External Network Virtualization: Individual parts and multiple networks combine together to form a single virtual unit.

2. Storage Virtualization

Storage Virtualizations is where the virtual single storage system gets managed by multiple servers. There are several major benefits of Storage Virtualization that will increase the overall performance, improve functionalities, and maintain smooth operations. Storage Virtualizations are of two types namely: Block and File Storage Virtualizations.

  • Block Storage Virtualization: Storage Virtualization is a type of virtualization that takes over from the disk level after getting replaced by the controllers. This functions before the file system level.
  • File Storage Virtualization: This is important for every server that makes use of the storage to install software, in cases where file system level is required.

Benefits of Storage Virtualization

  • Easy and simple updating process.
  • Has increased storage management.
  • Better utilization of storage systems.
  • Downtime reduction and increased capacity.

3. Memory Virtualization

Memory Virtualization is a concept in which multiple memories across various servers are bound together to form the virtual singular memory. Through this, bigger memory can be accessed. Memory Virtualization focuses on providing enhanced and better memory to carry out functions.

  • Application-Level Control: The applications of this system run on the device that is directly connected to the memory through an API system or a file system.
  • Operating System Level Control: The operating system (OS) in this system connects with the memory pool and makes it available to all the applications that are present in the process.

4. Software Virtualization

Software Virtualizations possess the ability to let computer systems run on a guest Operating System (OS). The concept of Software Virtualization is that the primary system is installed with the ability to develop an individual environment virtually, and simultaneously run it. There are three types of Software Virtualizations, they are:

  • Operating System
  • Application Virtualization
  • Service Virtualization

5. Desktop Virtualization

In the IT (Information Technology) fields, Desktop Virtualization is the very common virtualization type. The majority of the workplace, related to IT, make use of this virtualization. In Desktop Virtualization, the desktop of the user can be virtualized and data can be stored in a common server that provides the user with the ability to access their virtual desktop from anywhere at any time. 

Desktop virtualization ensures the security of the data and protects any form of data that might transfer through secure protocols. It has some well-known benefits including easy portability, and mobility, and can be efficiently managed. They can also be updated easily.

6. Application Virtualization

This is a virtualization type where all the elements, information, and characteristics of an application will be stored on a server. Application virtualization allows the users to make use of the application and access it from the server. 

Application virtualization encapsulates the elements of a specific application and virtualizes it on another server that enables all the users to access those applications without the requirement of installing them on the target device. There are two types of application virtualization, they are:

  • Hosted applications
  • Packaged applications

7. Server Virtualization

Hardware virtualization is also called Server Virtualization. This type of virtualization denotes the system of developing multiple abstracts in a single server. Server Virtualization divides the server’s physical environment into multiple environments virtually where each and every virtual environment can run on its own, as an individual environment. There are independent environments such as the VPS (Virtual Private Servers).

Advantages Of Virtualization

There are several benefits of using virtualization. Mentioned below are a few major advantages of virtualization.

  • Easy and simple procedure for backing up data and also ensuring data recovery management after a disaster.
  • Multiple operating systems and applications can run simultaneously on the same server.
  • Overall flexibility and efficiency of the hardware increase. 
  • Reduces overall expenditure of the hardware setup can be reduced.
  • Virtualization conserves energy.
  • Good uptime is provided.
  • Resources get deployed faster.
  • Servers can be used to the maximum extent.

Disadvantages Of Virtualization

Everything has its own pros and cons. Likewise, virtualization also has a few drawbacks. They are:

  • The implementation process is expensive.
  • Scalability issues arise over the long run.
  • Though it is convenient, the process is time-consuming.
  • They have quite a few limitations and there remains a sense of uncertainty because of that.

Few Final Words

Though there are a few drawbacks of virtualization, the overall efficiency of virtualization makes it a great concept. Make sure the service providers have all the essential tools that will be needed to manage and maintain the virtual environment, before making a purchase.

Cloud Computing And Its Essential Parts

What is cloud computing?

Cloud computing is the facility for providing an on-demand computer system based on availability. The data storage availability is another feature of cloud computing as it does not allow the user to directly manage it. The term is usually used to elaborate over the matters which are concerned with the data centers which provide information to various users all over the world. The predominant type of cloud of today is the large cloud which has the functions spread over the various locations from the central servers. The functions which are distributed on multiple scales are managed by the system of the large clouds. The connection to the user is comparatively closer than most cases and in these cases, they are known as the edge server systems.

Cloud computing is reliably on the point of the available resources which helps to achieve the correctness, coherence of the scale. The economies of scale are also judged by the reliability of cloud computing.

Its components

Storage-as-a-Service:

It is the component of cloud computing where you can use the storage. It is the one which we usually operate with the aid of physical methods such as using the remote site. This feature is also known as the disk space. There are other components on the cloud but this is the main component as they are dependent as a Storage service.

Database-as-a-Service:

This is the live database component of the cloud. It had the functionality which works through the physical features in the local machine. The main objective of this particular component is to reduce the cost of the dB by the usage of the software as well as hardware in the making.

Information-as-a-Service:

The information which can be accessed from anywhere on the web is the component named above the remote information. It can be pulled in with the help of this component. Remotely fetched information can always be helpful to the user. The remote information includes facts like livestock prices, internet banking, online news, credit card validation and so on.

Process-as-a-Service:

This is a process that helps in the combination of the various data and services present in the cloud. The process happens with the hating of the same or the equivalent cloud-computing resource. The remote information can also be compiled in this case. This is a feature mainly used for the purpose of the business. In businesses, the key method is to collect information and form process. The entire procedure helps in the delivery in demand. The mobile network services are part of this. The key services of this particular section are used from the component of cloud computing.

Application-as-a-Service:

The component named above is also known as the SAAS which is basically the entire model made for the use of the clients. This is a feature mainly made to serve the users on the internet. These users, mostly use the browsers to search for information. The internet facility is thus provided to the end-users. The front line users do not usually get the benefit of this component. The front end users must develop this component for the use of the end-users. The ultimate measures are taken by the  Salesforce, Gmail, Google calendar and so on.

Platform-as-a-Service:

This is the component of the app where the app is basically created, stored and undergoes testing. The implementation of the app also occurs here. The component level is the one that allows for the creation of the level of Enterprise and this application. This makes the cloud cost-effective.

Integration-as-a-Service:

This component is around the notion of building an application that can be incorporated with the other applicants. The medicating process within the exercise and local machines are also Carried out by this. The stacks from the kids are usually brought into and the local machines communicate with it. Google maps are an example of this feature.

Security-as-a-Service:

As far as customers are concerned, this is the most important component as they are ones who need security. The operations are handled delicately here and the security features are almost three dimensional in nature.

Management-as-a-service:

This component of the cloud helps in resource utilization, virtualization and server up and downtime management.

This is the role model feature of the cloud which makes it a type of small model admin if the app.

Testing-as-a-Service: Testing-as-a-Service refers to the testing of the applications that are hosted remotely, whether there is a requirement to design a working database and there is enough security for the applications and so on. This will be tested even with two or three cross clouds. This will also be a component in the development of cloud products.

Infrastructure-as-a-Service:

This is the entire infrastructure of the app built. The processing and the purchasing of them all and it’s resources occur in this component. The processes occur right in front of us but often we cannot see what happens at the back of the screen when it works. This has several back features as well.

Characteristics of cloud computing

The special publication includes the 5 characteristics which are present:

On-demand self-service:

The online control panel enables a user or a consumer to utilize on-demand self-service which is a type of cloud service in cloud computing. Unilateral allowance on working facilities like computer networking provides service to the user. The services can be utilized whenever needed by the consumer as per their requirements.

Broad network access:

This is basically available in a private cloud network. The various cloud computing services are available and can be accessed through the means of a wide range of devices like tablets, PCs, Macs, and smartphones.  Resources are made available to all and it is possible that it can be accessed through the means of standard mechanisms. The standard mechanisms often use by various different clients as has been mentioned before.

Resource pooling:

The provider’s computer sources undergo pooled and multiple consumers are served using a multi-tenant model. The consumer demand determines the multi-tenant model which are various in nature and programmed according to the basics of the user’s requirements. There exists partial location independence in which the exact location cannot be controlled or understood by the consumer which is available by the provided resources although consumers can specify the location of the work done such as country or state.

Rapid elasticity:

This is mainly dependent on customer demand. Whenever the customer wants it, the level of the rapid elasticity increases and on the other hand, sometimes the deploy becomes low. This is the major fact of rapid elasticity that it depends greatly on customer demands.

Measured service:

At some point in its making, cloud computing can change the resources on its own. This is a major factor in the development of cloud computing. At some point of its existence, the organizer develops on its own for the user benefit.

Different elements of cloud computing

SP 800-145 also defines three deployment models – private, public and hybrid – that together categorize ways to deliver cloud services.

  • Public Cloud: This model is responsible for the making of resources like the storage space and the networking available to the general public.
  • Private Cloud: This model is responsible for the distribution of the assets to the private grouping of infrastructure. It helps to fulfill the goals of a partnership and offers a secure environment due to its private model.
  • Hybrid Cloud: This is a mix of both private and public clouds for a single company.

This is what we call cloud computing in brief. In a nutshell, whatever you see when you browse is a part of cloud computing.
