How important is the cloud?

The importance of cloud

Developing the infrastructures revolving around the support & services of cloud computing has now accounted for more than one third of all IT spending worldwide. Meanwhile spending on traditional, in-house IT continues to decline 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. Cloud computing services cover a vast range of options now, from the basics of storage, networking, and processing power through to natural language processing and artificial intelligence as well as standard office applications. Pretty much any service that doesn’t require you to be physically close to the computer hardware that you are using can now be delivered via the cloud. It has become that much more practicable to switch to cloud. Predictions show 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, security and management services”.

According to Gartner, global spending on cloud services will reach $260bn this year up from $219.6bn. It’s also growing at an even faster rate than expected. Why wouldn’t companies spend so much on cloud? No more buying servers, updating applications or operating systems, or decommissioning and disposing of hardware or software when it is out of date, as it is all taken care of by the supplier. Some of the major organizations that use cloud services are Amazon, Facebook, Alibaba, Netflix and many many more. Cloud computing is becoming the default option for many apps as well. 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. Cloud applications can be updated, tested and deployed quickly, providing developers with necessary feedbacks and control. A key difference between cloud and web applications is their architecture. A web application must have a continuous internet connection to function. Conversely, a cloud application performs processing tasks on a local computer or workstation. Cloud application allows the user to work offline as well but need an internet connection to download or upload data.

Hybrid cloud is where everyone is in reality. Some data in the public cloud, some projects in private cloud, multiple vendors and different levels of cloud usage. It is popular because of the option for disaster recovery incases of failure and maybe some companies don’t like others handling their data. Nonetheless, cloud computing has shown continuous growth, adaptation and is definitely the technology of the present and the future.
