There are four main types of cloud computing: Private clouds: Clouds that can be set up online or with on-premises hardware that only select users are allowed to access. Public clouds: Clouds in which the platform and software is provided by a third party and shared by all users, and each user gets their own login. Hybrid clouds: A cloud solution that integrates a private and public cloud to work cohesively as one cloud infrastructure. Multi-cloud: A cloud solution in which multiple private and public clouds may be integrated together under one infrastructure.
