Cloud information systems are a very complex and multifaceted class of IT environments. There are many options for using the cloud, which, in addition, can be adapted to any, even unique business needs. But there are three classes of clouds that largely determine the nature of their use: public, private and hybrid. We tell you how they differ from each other and which cloud to choose.
The public cloud content writing service
is the one most familiar to the general public. Mail, document storage, and many everyday services are all based on public clouds. They are managed by cloud providers that provide deployed services to multiple clients.
In this case, only the provider has access to manage the equipment on which the cloud is based – the user can only regulate the volume of services he needs.
Such clouds are very convenient for small companies. It is very easy to get the necessary service here - a CRM system, website hosting, etc. You do not have to invest in infrastructure, everything necessary for the service to work is provided by the provider itself, and the cost of renting equipment is already "sewn" into the cost of the service.
Paying for a service hosted in a public cloud is also very convenient – the invoice will be issued only for those services and in those volumes that the company actually uses. At the same time, the volumes of services can be regulated. This is especially important for those companies whose work is highly seasonal.
During peak load periods (for online stores, this could be the eve of major holidays, seasonal surges such as Back-To-School or seasonal sales), you can literally increase the necessary resources in a minute by making a couple of clicks in the control panel. Returning to the previous volume is just as simple. Finally, there is no need to administer or, even more so, ensure the operability of the servers – this is entirely provided by the provider itself.
But public clouds have their downsides. They are good for small projects. As the business grows and the project scales, the company will sooner or later find that the capabilities of Public Cloud are not enough.
In addition, data requires special attention: if a company works with personal data (and any CRM system contains, for example, contact information of clients), then the cloud provider whose services the client uses must ensure the protection of information prescribed by law.
Finally, the company becomes truly dependent on the provider – if it crashes or services become unavailable, the client’s business stops as well. In addition, users have to take care of the data that is stored in the public cloud.
All this requires attention when choosing a cloud provider. It must have a reliable infrastructure on which the cloud is based, provide guarantees of high availability of its services, offer additional services that will solve related problems.
For example, Rusonyx guarantees its clients the highest level of service availability. Such confidence in its own capabilities has its own basis: the equipment on which they are based is located in one of the most modern and reliable data centers in Russia, DataPro, which complies with the global TIER IV standard.
You can manage all the services offered by Rusonyx from a single panel, where you can see the details of services down to the ruble. And to protect your information, you can use the additional service offered by the company – data backup and recovery.
Summary: The public cloud is the best choice for those companies that do not have significant resources and want to focus on their business, leaving many of the accompanying complex technical tasks to professionals.
A private cloud is owned by one company. In order to deploy it, you need your own or rented equipment, as well as a full set of necessary software - virtualization tools, operating systems, application solutions, systems necessary to ensure the operation of the cloud.
It is easy to guess that creating a private cloud requires serious investments, not only in equipment and software, but mainly in the competencies and personnel that will be engaged in supporting the cloud. Because all possible risks associated with ensuring the operation of servers and software fall on the company itself.
However, many companies, especially large ones, prefer to create their own private clouds. They have a number of advantages over public ones.
Firstly, a private cloud gives a company confidence that all its resources are at its sole disposal. And it’s not just about the equipment, but also about the data, which is becoming the main asset for most businesses today. In a private cloud, the “provider problem” simply does not exist.
Secondly, a private cloud is becoming an optimal choice for those organizations that operate under legislative restrictions. The company can ensure compliance with regulatory requirements (and they may concern not only personal data, but also the use of certain software or equipment, the availability of specialized information security solutions, and many other aspects) without relying on a third-party contractor.
Another opportunity of a private cloud is the use of services that are not available in a public cloud. These can be specific information systems, special platforms (for example, an application development platform or a microservices platform), special infrastructure elements.
