A private cloud is like having your particular corner in the digital world. It’s a computer setup where only one organization can use the cloud, its services, and everything that comes with it. Even though a company might set it up, it’s exclusively for one user, and they don’t share the resources. Private clouds are hosted on infrastructure owned by the organization, offering a high level of control and security. However, they may be more costly than public clouds.
The private cloud market is expected to grow at a CAGR of 18% by 2030. Private clouds are mainly used by big organizations that need a computer setup.
