Importance of Cloud Computing

Cloud computing is a technology that makes it possible to store, process and manage data through virtual servers that are hosted on the internet. This is in contrast with the traditional way of storing data on a physical device such as a computer, phone or tablet.

This technology has grown quickly to take position as a genuinely iconic innovation that started just as the usual tech buzzwords but then went on to cause massive disruption in the way we access and use computing resources. While the term itself might feel a little exuberant, and sure it does, the use and importance is so valuable and widely entrenched. 

For some, it might sound a bit distant but we use it daily without knowing. If you own a smartphone, computer or tablet,  then you are already a big consumer of cloud computing in one way or the other. All the social media services we enjoy, for example, are offered as a service via the cloud. Facebook, Instagram, WhatsApp, Twitter, name it. Cloud computing relies on sharing resources to achieve economies of scale.

For those to whom cloud computing is new, questions like why is cloud computing important or why do we need cloud computing are common and expected. In this article, we'll answer those questions, explain the importance of cloud computing and more including why cloud is the future.

Why is cloud computing important?

It enables you to run programs, store and manage files without using your device's resources. In other words it makes it possible to use your device to get your work done without having to worry about the critical IT infrastructure that facilitates the programs you use. You can use your device without storing anything on it.

Instead, you store all your stuff in the «cloud», a server that is hosted on the internet. You can run as many programs as you can dream of without having to download and install them on your computer, because these programs are stored in the cloud. You can take as many photos or videos and instead of filling up your device space, you store them in the cloud. If you are a developer, you can develop and test massive projects without worrying about servers. If you are a musician, you can record lots of songs and store them all in the cloud. As you can see, cloud computing is for everyone. It is for every business, every organization, and even governments. It's that important.

What was life like before the cloud?

Before cloud computing came, you had to install any program you wanted to use, store and manage all files from your device. This was overwhelming because the space in your computer, for example, would fill up quickly and stall your work. What cloud computing did is that it literally migrated the data infrastructure component of computing from the device to the internet. So instead of storing stuff in your device, you store them online. Of course cloud computing is more than storage, as it also encompasses other important functions such as processing, streaming and management. 

Why is cloud computing important for business?

Cloud computing is important for businesses because it allows them to access technology resources without the hassle and expense of building and maintaining their own IT infrastructure. With cloud computing, businesses can access the resources they need, when they need them. If the needs change, the cloud can be easily scaled up or down to accommodate those changes. By moving to the cloud, businesses can reduce or eliminate the need for on-premises servers, software, and storage, resulting in lower IT costs. Cloud-based solutions are also more secure than on-premises systems, making them a better choice for businesses that handle sensitive data.

Here is a categorized breakdown of why cloud computing is important in modern systems and business. 

Collaborative importance of cloud computing in current era

  • Data access on the go: With cloud computing, your teams can access your business data and tools anywhere, anytime without having to install applications on devices. This allows employees to be mobile and access data on the go, whether they are at the corporate office, in the field, on the road or even from their homes. This is great for businesses that need to stay constantly connected to their customers and employees.

  • Multiple users: Cloud computing allows multiple users to access the same application at the same time, which saves time and increases productivity. Take the example of a document like a company report in Google docs. Many people can access and work on the same document within a short time, each doing different tasks. Contrast this with having, say 10 people contributing to such a document while working separately from their computers. It would take long before all contributions are harmonized to arrive at the final polished report. 

Infrastructural significance of cloud computing

  • Freedom to focus on business, not infrastructure: Instead of spending your precious time maintaining complex hardware and software, you simply pay the cloud service provider to use these resources. The provider also manages the underlying infrastructure, which means your business can focus on running its core operations and not attending to infrastructure demands. Because you pay only for the resources you need, you can plan more accurately for your company's future needs.

  • Freedom to scale up or down: Because of the flexibility offered by cloud-based solutions, a business can easily increase or decrease its usage according to its needs. When it grows and needs more resources, it no longer needs to purchase additional hardware, which would take up valuable capital. The same is true for a business's data storage needs. Businesses can also make changes in the cloud in a matter of minutes instead of months.

  • Security: The security of the IT infrastructure is a key concern for all businesses. A breach of data can devastate a business's revenue, customer loyalty, and brand positioning. Cloud-based applications offer advanced security features like granular permissions, access management, and federated roles that help businesses minimize the risk of data breach. Using cloud-based services allows companies to use encryption and other security measures that are more than sufficient for their business. Further reading: Top 6 Cloud Computing Security Threats.

  • Multiple cloud options: Businesses can choose to use the public cloud, private cloud or hybrid cloud, based on what best meets their needs from time to time. Each option offers different features. 

Cloud computing importance in terms of costs

  • Capital equipment investments: With cloud computing, you do not require capital equipment investments. As a result, you don't have to worry about equipment obsolescence. With cloud-based services, you can add additional bandwidth whenever you need it, and it is more affordable than ever. As a result, your cash flow will be in line with the actual operating costs.

  • Salaries & wages: Using cloud storage can help reduce the number of full-time IT employees required to maintain the IT infrastructure. Additionally, when in need of cloud computing maintenance and upgrades, the service providers handle all that, reducing the amount of IT FTEs needed to maintain them. This means that it's not your responsibility to keep it maintained. And you'll save a lot of money in the process.
