Cloud Computing: What is It & How It Works?

Cloud computing is a popular topic that presents numerous questions that intimidates even the smartest experts. Today we want to share our knowledge and to help you understand the basics of it. Then you will be able to come to a decision whether you should implement the technology into your company or not.

Big data cloud computing is a way for companies and individuals to access various digital resources over the internet. Cloud solutions usually reduce or eliminate the need for on-site software and/or hardware. For instance, if someone buys a hard drive backup service, he or she can transfer his or her files through an internet connection, as they are stored in distant servers. Usually, the data would be in multiple places allowing better security and redundancy that is not possible with standard hardware solutions.

Cloud technology provides the possibility to increase available resources. Some people even refer to it as “IT outsourcing.” If you do not have an on-site server big enough to cover the needs of your company, or preferred type of software, there’s a good chance that cloud services could fill that role.

Get the understanding of cloud computing technology

For many people, cloud computing may seem like a distant concept, but they most likely use it daily without even realising it. Here are some examples:

Checking your email from anywhere due to the cloud-based webmail client.

Being able to rent software apps especially considering how quickly some software becomes obsolete.

Using a shared online spreadsheet with colleagues from different offices.

Saving files in an online cloud storage account and later accessing it.

Main cloud technology characteristics

First, this technology provides special managed services that allow you to concentrate on whatever task you are doing that is supported by it. Second, it provides secure storage. For example, working on Google Drive, which has a cloud-based word processor, gives you an opportunity not to worry about doc’s safety.  Everything is automatically saved every few seconds. You can enjoy the benefits of the technology and be sure the service provider will take care of things like file storage and saving.

Also, a significant advantage of Big Data technologies in cloud computing is an opportunity to subscribe to the majority of cloud services without being locked into long-lasting contracts. Besides, it makes its respective services available privately or publicly, too.

Advantages and disadvantages of cloud technology

Every technology in the world has both pros and cons. Let’s together go into more depth about the benefits of cloud technology, and then examine the potential disadvantages.

Less on-site IT staff

Many cloud computing service providers guarantee a very high level of constant uptime. For instance, a company may assure trouble-free service all year at all the time, and if it fails - you do not pay for service. If you pick a reliable provider, your troubleshooting will not be dependent on on-site IT professionals.


You can easily purchase only the cloud services you want, and have the option of upgrade later when necessary. That means you are not obliged to make significant investments in physical equipment that may get stolen, break down, or age out over the years.

Fewer maintenance problems

When you are working with physical computer networks, hardware and software, you have a vast of maintenance needs and challenges.  You must use resources for frequently optimising different processes. All of that takes valuable time and money. Besides, it distracts your attention from other critical needs. However, cloud computing usually will allow you to log into a well-maintained online interface and use the latest versions of content and cloud applications.

You cannot use without internet

The majority of modern providers of cloud-based technology is very reliable. They can guarantee an extremely high percentage of uptime, nearly unbelievably high. But you can have problems if you solely rely on the internet to access your files, as the internet connection can go down. Without it, you will not be able to use your cloud system.

Possible issues with migration

If you want to move your files over to a different provider, you may face quite a complicated process than you think. Even as innovations are occurring to make this task easier, there are still big incompatibility issues that can make transferring a painful experience.

Lower client control

A lot of providers do not show infrastructure details, which may be frustrating to clients that want to handle their administration needs themselves.

What is the future of Cloud Computing?

Cloud computing as many things in our world is following a trend of shifting into a wireless and paperless word. Here are some predictions for cloud computing  in the near future:

IT companies will continue to prefer a hybrid or public cloud services.

To be competitive, providers must bring products that are secure and innovative.

They must prove that their technology is the latest and fastest available. But at the same time, everything is being stored and delivered safely.

It will move beyond computers.

Analysts think that cloud technology will be widely used outside the computing world in the near future. It already appears in other industries, but still to a relatively small extent.

Clients will buy cloud-based services straight from providers.

Until recently, companies or individuals that wanted to benefit from cloud computing services usually bought them from external vendors. But consumer analysis shows the increase in preference for transparent, direct transactions between customers and service providers. The decrease of control from third-party entities gives clients access to pricing information. While at the same time allowing providers to get feedback about how their users enjoy respective products.

Now you have a basic idea of cloud computing and how it works. Also, you get to know why it has become so popular and what developers and analysts predict for this technology. Equipped with your new knowledge, you may now feel more confident in deciding if your company should incorporate cloud computing.
