Do you know the differences between public, hybrid and private cloud? Do you know which is the best for your company? Find out in this article what are your main differences and the advantages of adapting your business to the cloud computing system.
The concept of Cloud, also known as cloud computing, is based on the use of storage capacity, memory, use of shared servers and services that are connected and interconnected over the internet. The principle is the same as in grid computing, but its resources are available through an online (cloud) network.
Data storage, tools, projects and other resources, can be accessed from anywhere in the world, at any time, without the obligation to install programs or data tools. Everything is done remotely over the internet, where most companies have been adapting their servers for these cloud models, without the need to purchase physical options.
Public, hybrid and private cloud
Currently the access models offered by the cloud computing system are:
- Public Cloud
- Hybrid cloud
- Private Cloud
Its main differences are related to the level of control of your infrastructure and how they can be configured by your IT manager or professional in the area.
Differences between public, hybrid and private cloud
Public Cloud
The Public Cloud is used by different types of users, who have access to the resources of the same machine / server. All information and resources of this service are intertwined and are shared between different accounts, which brings the advantage of being a cheaper service and although it does not seem, it is also very secure, as the information is mixed, making life difficult for those who intend to use the data for other purposes considered non-legal.
In this case, the system manager will create a strict access control policy, where the vulnerability of the account becomes almost zero.
As already mentioned, among the advantages of the public cloud is the investment division of users to maintain the system. It is the option that requires the least investment of the three. Some of the most reputable companies offering the public cloud service are Microsoft, Google and Amazon AWS.
3 Steps to a Successful Cloud Migration.
Private Cloud
Before we talk about the hybrid cloud, we need to talk about the private cloud. This cloud computing service model consists of a system created and configured to meet the needs of a single company. In this way, all data control, tools and other resources are available exclusively to your IT manager.
In this type of cloud, it is possible to create models that 100% cover the needs of your company, including more dynamic options and that facilitate the maintenance and updating of resources.
However, in the private cloud, as it is something personal, all the costs and investments to make the system 100% functional, leave the finances of a single user. This is the most expensive option of all.
Hybrid cloud
The hybrid cloud is the “mix” of public and private cloud. This has been the cloud model most used by small and medium-sized companies, since the level of flexibility and the need for less investment compared to a private network, is what attracts the most in this service.
The hybrid model adapts to different structures and is indicated mainly for companies that suffer from varied peaks in access to information during their daily lives.
For example, your company needs to use only 70% of the capacity of a server during the day, but at any given time the system needs 100% of the capacity and the ideal was that there would be an additional 10% beyond the current capacity.
This is where the hybrid cloud comes in. The 30% that remains during the other hours of the day is divided among other users and when there is a need to “borrow” more processing capacity, the model focuses efforts on your system.
Another indication of the hybrid cloud model is for companies that have restrictions on placing 100% of their services in the public cloud, with the need to have a private network.
In cases of instability of the local (private) system, the business does not suffer major impacts either, as the functionalities are continued in the public structure.
Hire an IT manager and he will make a specific analysis of what your company needs and which cloud model will bring the best benefits to your business.
