What is Virtualization in Cloud Computing?

Characteristics of Virtualization

  1. Resource Distribution: Using a single computer or a network of connected servers, virtualization allows users to create a distinct computing environment from a single host machine, allowing them to limit the number of active users, reduce power consumption, and maintain easy control.
  2. Isolation: Virtualization allows guests, whether they are operating systems, programs, or other entities, to execute in a completely isolated environment. The guest application interacts with an abstraction layer, which offers access to the underlying resources, to carry out its tasks. The virtual machine can monitor the guest’s activity and avoid damaging attacks on the host.
  3. Aggregation: While it is feasible to share physical resources across multiple guests, virtualization also allows for aggregation, which is the inverse of sharing. A collection of individual hosts can be linked together and shown to visitors as a single virtual host. Cluster management software, which harnesses the physical resources of a homogeneous set of machines and portrays them as a single resource, is used to provide this feature.
  4. Security: The ability to entirely transparently manage the execution of a guest program brings up new options for creating a secure, controlled execution environment. Guest program typically perform all of their activities against the virtual machine, which subsequently translates and applies them to the host applications. A virtual machine manager can monitor and filter the activities of guest program, preventing some potentially dangerous processes. The host’s resources can then be concealed or merely protected from the visitor. When dealing with untrusted code, increased security is a must.
  5. Portability: Depending on the sort of virtualization in question, the concept of mobility can be applied in a variety of ways. A hardware virtualization solution packages the guest into a virtual image that can be safely transported and operated on top of other virtual machines in most circumstances. The binary code representing application components (jars or assemblies) can execute without recompilation on any implementation of the matching virtual machine in the case of programming-level virtualization, as implemented by the JVM or the.NET runtime.
  6. Availability: Virtualization software offers a variety of benefits that consumers won’t get on physical servers, like increased uptime, availability, fault tolerance, and more. These features assist users in avoiding downtime, which reduces efficiency and productivity while also posing security and safety risks.
  7. Emulation: The virtualization layer, which is a software, controls the execution of guest program in a virtual environment. In terms of the host, a whole distinct environment can be simulated, allowing the execution of guest program that require a specific set of features that aren’t present in the real host.

What is Cloud Computing?

Characteristics of Cloud Computing

  1. Self-service on-demand: Because Cloud Computing services do not require any human administrators, users can provide, monitor, and manage computing resources as needed.
  2. Rapid elasticity: Computing services should have IT resources that can scale out and in on a need-to-know basis. When a user requests services, they are given, and the service is scaled down once the user’s needs are met.
  3. Measured service: For each application and tenant, resource use is tracked, giving both the user and the resource supplier an account of what has been consumed. This is done for a variety of reasons, including billing and resource management.
  4. Resource pooling: IT resources (such as networks, servers, storage, applications, and services) are shared in an ad hoc manner across multiple applications and occupants. A single physical resource is used to serve several customers.
  5. Broad Network Access: One of the most intriguing aspects of cloud computing is that it is not limited by geography. Cloud computing is available via the internet and has a large access area. You may access your files and documents from any location in the world; all you need is a reliable internet connection and a device to get started.

Role of Virtualization in Cloud Computing

Advantages of Virtualization

  1. Limited use of Software and Hardware Components: Due to the general limited usage of resources, hardware and software resources are under-utilized. Because all of the user’s PCs are capable of meeting their daily computational needs, many of them are utilized often and may be used constantly without interruption 24 hours a day, seven days a week. Using these resources for other uses after hours could improve the efficiency of IT infrastructure. With the help of virtualization, this environment can be created.
  2. Shortage of Space: Data centers are rapidly expanding due to the constant need for more capacity, whether it’s for memory storage or compute power. Google, Microsoft, and Amazon develop their infrastructure by constructing data centers that meet their specific requirements. The majority of businesses are unable to afford to establish a new data center to accommodate increasing resource capacity. This contributes to the spread of a practice known as server consolidation.
  3. Enhanced Performance: Currently, the end user system, i.e. PC, is strong enough to meet all of the user’s fundamental processing needs, plus a variety of other features that are rarely used. The majority of their systems have enough capacity to host a virtual machine manager and run a virtual machine with acceptable performance so far.
  4. Increase efficiency and productivity: IT personnel will be able to spend less time maintaining physical hardware and IT infrastructure with fewer servers. Instead of going through the onerous and time-consuming process of applying updates server-by-server, install, update, and maintenance of the environment across all of the VMs in the virtual environment on the server will happen easily. The efficiency and production of your staff will improve if less time is spent on maintaining the environment.
  5. Reduce downtime and enhance resiliency in disaster recovery situations: When a physical server is damaged, someone is responsible for replacing or repairing it, which can take hours or even days. It’s simple to provide and deploy a virtualized environment, allowing replication or cloning of the impacted virtual machine. The recovery procedure would take minutes, rather than the hours it would take to deploy and set up a new physical server, greatly improving the environment’s resiliency and ensuring business continuity.
  6. Easy: A developer’s best buddy is virtualization. It effectively separates development and production environments without the need for additional hardware. Cloning a VM to create testing environments is incredibly straightforward. You can use it to test features and fix bugs without affecting the actual product. Developers in traditional hardware-based systems must be concerned with all updates and upkeep for their development equipment. It’s also a constant issue to keep an accurate picture of live servers for testing. Virtual machines (VMs) easily resolve all of these concerns. Virtualization allows developers to play with an infinite number of flawlessly reproduced virtual machines on demand. Virtualization is used by developers to speed up updates, increase software security, and maintain a smooth pipeline between development, testing, and deployment.
  7. Reduction Of Expenses: Computing power is not cheap. If the only method to increase resources is to buy new hardware, the cost quickly mounts. It also provides for remote access and rapid scalability. You can examine your current architecture and uncover wasted or idle computing resources using virtualization techniques. Organizations frequently deploy servers to run applications that only require a small portion of their available resources. These servers are never used to their full capability. To make matters worse, these servers are completely idle while their applications are not operating. In a virtualized environment, you may accurately assign each VM the amount of computing resources it requires to perform its function. Other VMs and their apps can then use the leftover resources. Virtualization costs are almost always less than traditional costs.
