In recent years, cloud computing is one technology that has been in humongous demand. And no matter the age of an individual every other individual is lately taking either an [url=https://www.mercurysolutions.co/cloud-computing-certification-training-courses?utm_source=Nairaland%20(AS)&utm_campaign=29-2-2020]AWS or Azure certification[/url] to be cloud-ready.

What is cloud computing?

Cloud Computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. This is one tool that allows organizations to adopt this tool to enhance their operating speed by boosting the operations into the servers, enhancing the storage, widening the databases, strengthening networks and software, using analytics, and intelligence over the cloud.

Cloud Computing as a service

First things first cloud is a service, that is majorly a bunch of huge private data centres that leases the computer resources to the clients (the organization using this cloud). Some of those clients also include random users who visit once in a blue moon like you are here reading my opinion.

The resources that are leased here are completely dependent upon what you are trying to accomplish, hence, the services are defined depending upon what you plan to do day in and day out. Thus cloud is offered in the following categories:-

Infrastructure as a Service -- IaaS
Platform as a Service -- PaaS
Software as a Service -- SaaS

Why are organizations continuing to invest in cloud computing?

No matter the cloud provider you are thinking of getting on board or have already brought on board they are either one of the three services (IaaS, PaaS, SaaS) providers then no matter which combination you opt for.

Organizations owning cloud computing tools with them don't have to pay rent, property taxes, or utilities on buildings that house data centres. They further do not need to invest in racks or the equipment that sits in them. This allows them to stay relaxed about any repairs or maintenance or even replacement in the equipment for that matter.

In fact, the need for hiring engineers to design intricate networks is also not required since there is no need to build programs while using cloud computing tools. to keep the systems up and running.

All this reduces an organization's cost by 35% annually. This allows a company to focus its IT efforts on creating code that is essential to improving processes and delivering products or services to customers. It is the 21st-century version of the "make or buy" decision, creating huge cost savings, and representing a compelling shift in IT spending.

Cloud computing further helps an organization in the following ways:-

Effective business focus: Engagement in cloud computing, allows organizations in staying relaxed about the fact that all its services will get executed using the internet without bothering about the day-to-day technical problems like backup or storage issues. Providing enterprises with more time to focus effectively on the business.

Enhances business performance: Companies adopting cloud computing will be getting reliable performance across the globe. The biggest advantage of cloud computing is the ability to update applications and services automatically.

High level of data security: Highest security to protect your data against unauthorized accessibility, loss of data or any form of change is the biggest benefit for an organization using cloud computing.

Highly Flexible: Even when there is a technical glitch, a partial segment of the cloud computing stop working, there is no need to fear as the other segments continue to work without any cause for complaint till the problem gets resolved.

Scope of Cloud Computing

If you look at the cloud computing industry a bit closely you’d find that :-

At the end of 2016, it was found that cloud computing is the hottest skill an IT professional could have.

In the final quarter of that year it was seen that the revenues of AWS and Azure clouds had risen up by 93% & 47% respectively.

By 2017, it was found that 18 million jobs were generated in cloud computing. In fact, in the last year (2019) AWS cloud was the market leader with a market share of 32% whereas Microsoft Azure had a market share of 29%.

This off late has made AWS has the most demanded certifications followed by Azure certification in the cloud computing industry.
Now about 75% of businesses across industries that have moved on to the cloud.
