Cloud computing and virtualization are just some of the biggest buzzwords in the IT industry. Both technologies are being adopted by various sectors to either improve or streamline their current workflow. However, due to the influx of overwhelming information, people still think both are the same. Although they share a common bond, virtualization and cloud computing are different.
Virtualization defined
Virtualization replaces some physical components with virtual ones. Some of these components include operating systems, network components, storage services, or computing environments.
It is like creating codes or software programs that function like their physical counterparts. Virtual servers, for example, can send and receive signals, even if they do not have physical chips or circuits. Also, virtualization allows multiple infrastructure resources to run on one machine.
Cloud computing defined
Cloud computing, on the other hand, delivers shared software-as-a-service (SaaS), data, or computing resources through the Internet. It allows users to access programs and data from the fileserver cloud, for example, instead of their computer’s hard drive. Cloud computing also utilizes several network servers to spread data-processing tasks across a network. Briefly, it is a type of Internet-based supercomputing.
Their differences
Both seem to be the same; however, they are two entirely different in terms of technology. Virtualization is a technology, while cloud computing is based on virtualization. Cloud computing cannot exist without virtualization, but virtualization can exist without the cloud. However, both maximize and utilize a business’s infrastructure and computing resources.
Despite their differences, why are they important?
Given their differences, virtualization and cloud computing both offer advantages for businesses. Below are some of the reasons why they can help them “achieve more for less”:
Advantages of cloud computing
Big Data – data is vital for any business, and computing power is needed to sift through them. Cloud computing can sift through unstructured data and help analyze them. This also gives them the advantage of keeping their business on top.
Flexibility – it is one of the main advantages of cloud computing. It allows entrepreneurs to connect with their businesses anytime and anywhere.
Scalability – since it is flexible, businesses can easily change their storage and operation needs to suit their needs. It also makes it easier for them to deploy what they need, when they need it.
Cost-effective – compared to traditional technology, the cloud is a cost-effective alternative since it can help lower overhead costs. The start-up cost is lower, and entrepreneurs can save on fees for software licenses, software updates, and data storage.
Secured data and information – IT managers and business owners can now achieve peace of mind with cloud computing. Stringent ISO security protocols are implemented to keep sensitive data and information secure. Security audits are performed regularly to eliminate possible online or hacking threats.
These are some of the main advantages of cloud computing. It is like a virtual office set up to help connect businesses 24/7.
Advantages of virtualization
Private and secure – virtual machines can easily replicate security requirements previously set on physical devices. Even the level of security for tools and resources can be set to private.
Decreased downtime – virtual servers run separately, which helps reduce server downtime. Although they share the same hardware, these servers can be serviced without affecting the other.
Maintenance can be done anytime, and it will not cause any disruption.
Small-scale virtualization – virtualization makes it easier to manage servers on-site. Businesses can also opt to buy fewer servers and optimize them effectively. Each machine can run applications and operating systems to fit a company’s needs.
Increased energy efficiency – since virtual machines can run on fewer devices, less hardware is required to accomplish given tasks. This also lowers the amount of energy needed to run machines, and the equipment is fully optimized for business use.
Faster installation and setup times – it usually takes days, weeks, or even months to procure business equipment. Also, it takes another week or more for delivery and set up. Virtual machines only take a few days to set up and install. Virtualization software tools, storage drives, routers, and virtual machines can be easily configured. The installation process is faster, which reduces setup time.
Virtualization can help businesses streamline their processes and reduce set up costs. It consolidates physical servers into a machine running several virtual machines.
As operational models, virtualization and cloud computing allow businesses to maximize their resources. All their current computing infrastructures are utilized efficiently to help companies prosper. They have differences, but both can help enterprises go forward and flourish.
