Computing for large organizations takes a lot of time and resources: huge capacities are required for computing activities. The issue of data protection is also acute – can your bank provide round-the-clock and reliable data protection against physical and virtual threats? Cloud computing solves these problems. Their application is relevant for banking as well.
What is cloud computing, and how does it work
Imagine that you run programs and work with data without worrying about purchasing servers, organizing data centers, connecting server racks, and configuring operating systems. This is Cloud Computing.
The cloud provider takes care of the whole routine. First, it creates data centers: installs servers, lays networks and installs software responsible for infrastructure management.
To use Cloud Computing, you agree with the provider and get access to your account. After that, you can use any resources and services it provides. At the same time, you pay only for the capacities used and do not incur any extra costs.
Cloud computing for business: why you need it
No severe company today can live without IT systems. Logisticians, personnel officers, retailers, taxi companies, hairdressers, restaurants, pharmacies, concert halls, travel agencies, banks – everyone has to deal with programs, servers, and other non-core stuff.
All these business structures do not claim to be technological giants. Yes, they don’t want to – it’s none of their business. Logisticians carry, restaurants feed, hairdressers cut. And to overtake competitors, you have to implement this very IT.
This is how miraculous servers, services, and operating systems appear in business. There is only one problem: you have to pay for all this – buy, rent, hire people. It is expensive. And don’t say it’s easy.
Fortunately, at some point, the IT gods sent cloud servers and services to earth that live somewhere with a service provider, and he monitors them, updates, and configures them. Cloud computing is an example of when someone takes all the risks and problems of operation, and you have to run a program on a cloud server that will save time for your logisticians and administrators.
In short, cloud computing is for those who need to solve IT infrastructure tasks but do not want to hire people on their own, set up servers, and make sure that the entire computer industry works.
Clouds private, public, and hybrid
There are many classifications for cloud systems. But we will ignore all of them and use the straightforward cloud computing deployment model. According to her, clouds are public, private, and hybrid.
This cloud is provided by a cloud computing platform provider separate from your business. It takes care of all the trouble of setting up cloud clusters and provides the necessary resources on demand.
He builds his business for his needs himself or, with the help of a provider, hosting a cloud platform on his infrastructure. In this case, the administration department purchases hardware, configures it and provides access to computing power to other departments within the company.
This is when part of the load and data remains in the internal cloud and is transferred to the provider’s public cloud. At the same time, connections are established between them, and they can exchange data.
