You probably already know the difference between public and private clouds. There’s also a hybrid cloud. The article takes a quick look at definitions and differences before these types of cloud computing move on to explain what type of cloud is best for you and your business.
Difference between the public cloud and the private cloud
A public cloud is essentially a service offered by a third party. It can host storage for different companies simultaneously on the same server. It can be used by programmers from different companies to create and execute their code simultaneously without interfering with each other. In short, the Public Cloud is open to all participants and can be used by different customers at the same time. A single server can serve different clients and collect data from different clients.
Private clouds have dedicated servers. These servers contain data from a single organization. It provides a platform for the people of the organization for which it was built.
In a public cloud environment, it is pay as you go. Customers only pay for the part and services of the cloud they use. They do not have to worry about other inaccessible parts of the public cloud because they are not connected to them or their organization. In a private cloud, administrators have to deal with the whole cloud. You must ensure that the installation actually meets the essential requirements for the name cloud. The costs in the private cloud model are higher because the company has to buy all the servers it needs and pay the employees who work with the cloud.
Public or private cloud – Which is better?
Although most people maintain that it is based on your budget, I would say that the budget should be allocated according to the type of business you do. Of course, if your budget is not large and you can’t afford to create clouds on site to store all your data, you can use the semi-private cloud, i.e. the hybrid cloud. But it essentially depends on what you want to do.
The data can be divided into different categories. Different companies have different types of data that can be classified as highly sensitive to less sensitive data. If your business processes highly sensitive data, such as customer credit card data, you need a local cloud regardless of budget, because public clouds are more vulnerable to hacking than private clouds.
Data from these organizations may also be stored partly on local servers and partly in the public cloud. The least sensitive part of the data goes to the public cloud to save server and maintenance costs, while the most sensitive part goes to the local cloud. Such an installation is usually called a hybrid cloud – because the company uses algorithms that link the public cloud to the private cloud and vice versa – naturally with sufficient precautions to secure the data with methods such as two-tier authentication and encryption, etc. – and this is why it is called a hybrid cloud.
Appropriate encryption: Most public clouds do not offer a good encryption system. Data can be encrypted when it reaches the server, but the path between the organization’s computers and the public cloud may not be encrypted. In addition, encryption methods on public clouds are not very good, as evidenced by several articles I have read on the subject. Again, a private or hybrid cloud is the best option. On the other hand, if you are willing to take a risk and the data is not very sensitive, you can encrypt the data using one of the many techniques (or encryption software available) before transmission.
