What is cloud computing, in simple terms?

Cloud computing is the delivery of on-demand computing services — from applications to storage and processing power — typically over the internet and on a pay-as-you-go basis.

The cloud computing race in 2020 will have a definite multi-cloud spin. Here’s a look at how the cloud leaders stack up, the hybrid market, and the SaaS players that run your company as well as their latest strategic moves.

How does cloud computing work?

Rather than owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider.

One benefit of using cloud computing services is that firms can avoid the upfront cost and complexity of owning and maintaining their own IT infrastructure, and instead simply pay for what they use, when they use it.

In turn, providers of cloud computing services can benefit from significant economies of scale by delivering the same services to a wide range of customers.

What are examples of cloud computing?

Cloud computing underpins a vast number of services. That includes consumer services like Gmail or the cloud back-up of the photos on your smartphone, though to the services which allow large enterprises to host all their data and run all of their applications in the cloud. Netflix relies on cloud computing services to run its its video streaming service and its other business systems too, and have a number of other organisations.

Cloud computing is becoming the default option for many apps: software vendors are increasingly offering their applications as services over the internet rather than standalone products as they try to switch to a subscription model. However, there is a potential downside to cloud computing, in that it can also introduce new costs and new risks for companies using it.

How important is the cloud?

Building the infrastructure to support cloud computing now accounts for more than a third of all IT spending worldwide, according to research from IDC. Meanwhile spending on traditional, in-house IT continues to slide as computing workloads continue to move to the cloud, whether that is public cloud services offered by vendors or private clouds built by enterprises themselves.

451 Research predicts that around one-third of enterprise IT spending will be on hosting and cloud services this year “indicating a growing reliance on external sources of infrastructure, application, management and security services”. Analyst Gartner predicts that half of global enterprises using the cloud now will have gone all-in on it by 2021.

The development of cloud computing and multicloud brings many advantages:

  1. Security of data: Cloud computing makes backup which protects from loss of data.
  2. Cost reducing: The operational cost can be reduced be less maintenance and installation of equipment.
  3. Accessibility: Easy access to the data with the use of the internet as well as the ability to transfer files fast and secure.
  4. Mobility: Possibility of using files and data at any time and place through the device.

With the above five trends within web development, we now turn our attention to broader trends that the web not only affect, but is acting as the underlying driver for.
