Pros and Cons of Virtualization (VmWare)

Introduction to the Pros and Cons of Virtualization (Advantages & Disadvantages of Virtualization)

When a simulated version of something is generated instead of a real version, this is referred to as virtualization. This could include storage devices, networks, operating systems, or even servers in the case of modern virtualization. It is a phase that started in the 1960s, when some of the first mainframe computers had their machine resources separated so that they could operate on several applications at the same time.

Since then, virtualization has permeated almost every aspect of digital life. Many people take advantage of what virtualization has to offer, from virtual machines that behave like real computers to console emulation.

Virtualization, like most innovations, has benefits and drawbacks that must be weighed before completely implementing a system or strategy.

The Benefits of Virtualization (Pros of Virtualization)


1. It is less expensive than traditional IT infrastructure

Since virtualization does not necessitate the use or installation of physical hardware parts, IT infrastructures find it to be a less expensive method to implement. There is no longer a need to devote vast amounts of space and large sums of money to build an on-site resource. You simply buy the license or access from a third-party vendor and start working as if the hardware were built locally.

2. It holds expenses under control.

Individuals and businesses may have predictable costs for their information technology needs because third-party vendors usually have virtualization solutions. A Dell PowerEdge T330 Tower Server, for example, costs $1,279 direct from the manufacturer at the time of writing. Bluehost Web Hosting services, on the other hand, can be as sluggish as $2.95 a month.

3. It lessens the amount of work.

The majority of virtualization service providers automatically upgrade the hardware and applications that will be used. The third-party vendor installs these updates instead of sending people to do them locally. This frees up local IT professionals to concentrate on other activities, allowing individuals or companies to save even more money.

4. It has a higher uptime.

Uptime has increased significantly as a result of virtualization technologies. Some service providers guarantee a 99.9999 percent uptime. And low-cost operators now guarantee 99.99 percent uptime.

5. It allows for quicker resource deployment.

When virtualization is used, resource provisioning is quick and easy. There is no longer a need to mount physical computers, local networks, or other information technology elements. It can be extended to the rest of the enterprise as long as there is at least one point of entry to the virtual world.

6. It encourages digital entrepreneurship.

Prior to the widespread adoption of virtualization, digital entrepreneurship was almost impossible for the average citizen. Almost everyone can start their own side hustle or become a business owner today, thanks to the numerous networks, servers, and storage devices that are available. Sites like Fiverr and UpWork allow everyone to hang out their shingle and start looking for work.

7. It helps to save electricity.

Virtualization is an energy-efficient system for the vast majority of individuals and businesses. Energy usage rates can be reduced when no local hardware or software options are used. Instead of paying for data center cooling and equipment operational expenses, funds can be used for other operational expenditures over time to increase virtualization’s overall ROI.


The Disadvantages of Virtualization (Cons of Virtualization)


1. Virtualization can be expensive to introduce.

When considering virtualization, the average person or company can incur relatively low costs. However, the deployment costs for virtualization environment providers can be very high. At some stage, hardware and software are needed, which means devices must be designed, manufactured, or purchased for implementation.

2. It also has drawbacks.

Not every application or server can function properly in a virtualized environment. This means that a hybrid system will be required for a person or company to operate properly. This also saves time and money in the long run, however since not every vendor supports virtualization and some may discontinue support after the initial implementation, there is still a degree of confusion when completely implementing this form of framework.

3. Virtualization introduces a security risk.

Our modern currency is information. You will make money if you have it. You would be forgotten if you do not have it. Since data is critical to a company’s success, it is often targeted. According to a Ponemon Institute survey, the total cost of a data security breach in 2017 was $3.62 million. To put it into perspective, the odds of being hit by lightning are around one in a million. One of every four virtualization users will experience a data breach.

4. It causes a problem with availability.

The main question that many people have about virtualization is what will happen to their jobs if their properties are unavailable. If a company is unable to link to its data for a prolonged period of time, it would fail to survive in its industry. Furthermore, since availability is regulated by third-party providers, the ability to remain connected with virtualization is out of one’s reach.

5. Virtualization causes a scalability problem.

Because of virtualization, you may develop a company or opportunity easily, but you will not be able to grow as big as you would like. When you first start out, you will be expected to be bigger than you want to be. Growth causes latency within a virtualization network since several organizations share the same resources. There is nothing anyone can do if a massive presence diverts attention away from other smaller companies.

6. Virtualization necessitates many links in a chain that must function in unison.

If you have access to local facilities, you have complete control of what you can do. Since multiple ties must collaborate to accomplish the same mission, you lose control with virtualization. As an example, consider saving a document file. You can save the file instantly and even make a backup with a local storage device, such as a flash drive or HDD. Your ISP link must be active in order to use virtualization. Your LAN or Wi-Fi must be operational. Your online storage option must be open. If any of these don’t work, you’re not saving the file.

7. Virtualization is time-consuming.

While virtualization saves time during the implementation stages, it costs users time in the long run as compared to local systems. This is due to the fact that additional steps must be taken in order to achieve the desired result.

When used properly, the benefits and drawbacks of virtualization demonstrate that it can be a valuable tool for individuals, SMBs, developers, and companies. However, since it is so simple to use, some administrators begin adding new servers or storage for all, resulting in sprawl. Many of the drawbacks can be mitigated by being disciplined and mindful of communication problems, which is why this is such a successful modern system.
