What are the different types of cloud computing (Public, Private, Hybrid)?

Cloud Server Hosting Services are delivered in three primary models: public, private and hybrid. Each model offers different trade-offs in cost, control and security. The right choice depends on your business requirements, compliance obligations and how your applications and data need to be managed.

Cloud deployment models include:

  • Public cloud: Computing resources are delivered using shared infrastructure managed by a third-party provider such as Microsoft Azure or Amazon Web Services (AWS). Public cloud environments offer scalability, flexibility and cost efficiency for many business applications.
  • Private cloud: Dedicated infrastructure is reserved for a single organization, providing greater control, customization and security for sensitive workloads and regulated environments.
  • Hybrid cloud: Sensitive systems run in a private environment, while less critical applications use public infrastructure to control costs and security.
  • Workload segmentation: Compliance-sensitive applications (HIPAA-regulated data, CUI) typically run in private or isolated environments, while communication and collaboration tools run in a public cloud.
  • Interoperability: Hybrid environments use secure integrations that allow applications and data to move between cloud environments while maintaining appropriate security controls.
