Basic stuff you need to know about it
Cloud computing is delivery of on-demand computing services that are contingent upon three processes that are essential for data processing: applications, storage, and processing power. Cloud computing plays a vital role for many companies today that need to pay for these services on a pay-as-you-go basis.
The cloud providers that are dominating today’s industry
There are four cloud providers with the most extensive amount of services. They are: SaaS players, Microsoft Azure, AWS, and Google Cloud. These are the cloud providers that reigned in 2020. However, the cloud computing will tend to continue changing with the incorporation of new strategies and methods to guarantee security, management, and data storage. As we will see below, SaaS is the computing service with the largest number of purchasers right now.
What is behind cloud computing functioning?
Some businesses don’t have or manage their own data storage systems, thus they rent access to those services that are offered by Cloud computing companies. Renting these services is only for businesses that don’t have an infrastructure for data management. Most of the times, they turn to these services to duck the costs implied when maintaining their own IT infrastructure. In the end, they find it more cost-effective to use this service than building their own IT systems.
Cloud providers offer the same computing services that a company would have with its own infrastructure. So, there’s nothing to lose. In return, IT businesses benefit from these rentals many of which come from big companies that need to focus on more relevant activities.
The computing services of the moment
Cloud computing services envelop a diversity of services which give customers the ability to store data, use networking, and process power through language processing and artificial intelligence. It also offers standard office applications. These services have grown to the extent that they are now covering all those activities that do not require personal management.
Examples of cloud computing
As said before, cloud computing offers a vast number of services. Among the services it includes are Gmail and cloud back-up on the smartphone. This option is particularly offered to small companies, but there is also a crop of other products that attract the interest of businesses that are much larger. All cloud computing services encompass data storage and applications management in the cloud. An excellent example of that is Netflix which relies on the cloud to store movies and provide video streaming.
Cloud computing is becoming the default option to operate most apps. This means software vendors are offering their apps instead of advertising or selling them as standalone products. Thanks to this, consumers just need to subscribe to their services and enjoy them.
However, this has disadvantages and risks. Cloud computing companies have to fix cloud downside issues at times and they always have to make ways to reinforce security to prevent hackers from breaking into the system.
The name of cloud computing
A fundamental concept behind cloud computing is the location of the service which comes to be an irrelevant thing to the user. For this reason, many people think that cloud computing is an idea that came out from old telecoms network schematics, in which the location was unimportant. In simple terms, telecoms and cloud computing operate remotely but distance is not a problem since all cloud data is accessible for the user.
History of cloud computing
Cloud computing is a relatively new term that first appeared by 2000, but the concept of computing cloud was already known for a long time. In 1960, there were companies that rented time on a mainframe when they didn’t have the infrastructure to operate. That was already happening in 1960.
These time-sharing services were overtaken when companies found out that it was more profitable to have their own computers. Due to this, these companies stopped using time servers for the moment and turned to the use of corporate data centers.
There were then variations of computing until the cloud computing we know nowadays. In the beginning, in 1980 and 1990, two new concepts that derived from renting computing services surfaced again but it was not until 2000 that the concept of Cloud Computing came into play. Cloud computing aimed to cover everything rental services that had to do with software and hyperscale cloud then.
Importance of the cloud
Building the infrastructure for IT management accounts is twice more expensive than renting computing services. According to a research, it accounts for more than a third of all IT spending. Despite this, it is evident that traditional in-house IT service is being preferred at the same time that other businesses lean towards computing cloud.
One-third of enterprise IT spending is projected to be on hosting and cloud services because it is cost-effective and more secure, according to some stats. This proclivity must be due to the the fact that companies are putting their trust more in the IT infrastructure, application, and management that IT companies are offering today. In 2021, such industry is expected to have all-in with the introduction of other services.
Owing to this, it is well-nigh impossible that global cloud spending will be reduced by 2021. According to experts, it will go up from $260bn to $219.6bn. The spending rate can even increase unexpectedly but that has to be analyzed with the passing of time. There’s uncertainty of how much of that demand is coming from businesses or is being created by vendors who stick to the cloud versions of their products.
Infrastructure-as-a-Service – all types
Cloud computing can be divided into three computing models. The first model is called Infrastructure-as-a-service and refers to renting building virtual or physical blocks of computing that act as servers designed for storage and networking.
The second type of cloud computing is Platform-as-a-Service, which includes many more things especially those related to middleware, database management, development tools, and operating systems. This service provides companies with the necessary tools to create apps.
SaaS or Software-as-a-Service is the delivery of applications which is currently most consumed by companies today. In SaaS, the underlying hardware is irrelevant to the user who is going to gain access to the data be entering the cloud. To gain entry, the user is given an app, a web browser, and a password that can be customized.
