There are three main types of cloud computing today. They provide similar resources and services but are not the same regarding their technical aspects. Which option will work best in your case? Learn the differences between public, private, and hybrid clouds!
What is a public cloud?
The public cloud, as the name implies, is open to the public. Its users can be private individuals, as well as companies or institutions. A single provider usually hosts hardware and services. It supplies external storage and access to computing resources over the Internet. Selected services are available free of charge, but overall, the option is quite cost-effective.
The downside, however, is that all infrastructure management issues lie with the provider. You can’t count on any individualization in terms of services and their prices, either. Sharing resources among all customers in a public cloud also involves the risk of efficiency drops. What’s more, many people accuse this solution of weaker security, but nowadays in most cases, they meet all standards, so there is nothing to fear.
What is a private cloud?
The private cloud is similar to the public cloud in terms of functionality, except that its resources can only be used by specific entities. The infrastructure can either be owned by a third-party provider or by the organization itself. This solution allows full privacy, minimizing the access risk (sometimes it is necessary due to legal reasons). With a private cloud, the entity using its resources has an impact not only on the type of security measures used but also on the number and rights of authorized users.
The user of a private cloud has full control over the development of the environment and customization of resources to suit his needs. The big downside of this option is the excessive cost, time-consuming maintenance, and great responsibility.
What is a hybrid cloud?
A hybrid cloud combines two modules – public and private. It lets you transfer data between them, as well as applications. This way, for example, you can communicate with customers through services available to the public and store the crucial data of the company in the private section. This option works best for organizations that have diverse operations. It is extremely flexible, making it adaptable to changing situations. It allows you to optimize resource consumption and infrastructure maintenance costs, which is why this option is becoming increasingly popular.
