Cloud Computing is a very fascinating term. AWS Summit 2022
What is cloud computing, in simple terms?
Cloud computing is the delivery of computer services — including servers, storage, websites, network, software, statistics, and intelligence — over the Internet (“cloud”) to provide faster innovation, flexibility, and scale economics.
How does cloud computing work?
Instead of having their own computer infrastructure or data centers, companies can hire access to anything from applications to storage from a cloud service provider.
Another advantage of using cloud-computing services is that firms can avoid previous costs and difficulties of owning and maintaining their IT infrastructure, and instead simply pay for what they use, if they use it.
Next, cloud computing service providers can benefit from a significant scale economy by delivering similar services to a wider range of customers.
What cloud-computing services are available?
Cloud-computing services cover a wide range of options now, from basic storage, network and processing capabilities, to native language processing and artificial intelligence and standard office applications. Mostly any service that does not require you to be physically close to the computer hardware you are currently using can be delivered by clouds - even quantum computing.
What are the examples of cloud computing?
Cloud computing supports a large number of services. That includes consumer services such as Gmail or a photo backup cloud on your smartphone, though apps that allow big businesses to manage all their data and run all of their cloud applications. For example, Netflix relies on cloud computing services to run its video streaming service and other business programs, too.
Cloud computing is becoming the default choice for many applications: software vendors are increasingly offering their apps as online services rather than standalone products as they try to switch to a subscription model. However, there is a potential reduction in cloud computing, as it may also introduce new costs and new risks to companies using it.
Why is it called cloud computing?
The basic idea behind cloud computing is that the service environment, as well as many details such as the hardware or operating system on which it operates, is not important to the user. It was in this sense that the metaphor of the cloud was borrowed from the old telephone network systems, when the social network (and later the internet) was often represented as a cloud to show that space did not matter - it was just a cloud of things. This over-simplification is the case; for many customers, the location of their services and data remains a major issue.
What is the history of cloud computing?
Cloud computing as the name has been around since the early 2000s, but the idea of using a computer as a service has been around for a long, long time - since the 1960s, when computer bureaus allowed companies to rent time on the mainframe, rather than buy it themselves.
These 'time-sharing' services were largely taken over by the growth of PCs, which made computer access more accessible, followed by the expansion of corporate data centers where companies would store large amounts of data.
But the idea of hiring access to computer power appeared a lot more often - for software service providers, utility computing, and grid computing in the late 1990s and early 2000s. This was followed by cloud computing, which actually captured the emergence of software as a service and hyperscale cloud-computing providers like Amazon Web Services.
How important is the cloud?
The construction of cloud computing support infrastructure now accounts for a large part of all IT applications, while using traditional, in-house IT slides as computer load continues to migrate to the cloud, whether these are cloud-based public services providers or private cloud. built by the businesses themselves.
Indeed, it is becoming increasingly clear that when it comes to business platforms, whether you like it or not, the cloud has won.
Technology analyst Gartner predicts that nearly half of all spending on software software, infrastructure software, business process services and system infrastructure markets will be shifted to the cloud by 2025, up from 41% by 2022. It estimates that about two-thirds of the cost. in-app software will be cloud computing, up from 57.7% by 2022.
That is the change that gained momentum in 2020 and 2021 as businesses accelerated their digital transformation plans during the epidemic. The closure throughout the epidemic has shown companies how important it is to have access to their computer infrastructure, applications and data wherever their employees work - not just in the office.
Gartner said the need for integration skills, faster operating procedures and integrated infrastructure will drive continuous cloud flexibility.
Cloud usage rates continue to rise. For the full year 2021, technology analyst IDC expects cloud infrastructure to grow by 8.3% compared to 2020 to $ 71.8 billion, while non-cloud infrastructure is expected to grow by 1.9% to $ 58.4 billion. In the long run, the analyst expects to spend money on cloud and final cloud infrastructure to see a combined annual growth rate of 12.4% for the period 2020-2025, reaching $ 118.8 billion by 2025, and will account for 67.0% of total infrastructure and infrastructure. of infrastructure. . The use of non-cloud infrastructure will be relatively low compared to $ 58.6 billion by 2025.
All predictions about cloud-computing use point in the same direction, even if the details are slightly different. The momentum they describe is the same: technology analyst Canalys reports that the use of cloud infrastructure services worldwide reached $ 50 billion per quarter for the first time.
