  2. To deal with low latency issues,
  3. To meet regulatory and data sovereignty requirements.

Advantages of Hybrid Cloud

  • Remote and distant employees can access data on demand with a hybrid cloud.
  • Hybrid cloud models optimize IT performance, provide business agility, and speed up market time.
  • Business continuity is improved, lowering the likelihood of potential downtime and associated costs.
  • It’s ideal for firms that want more data security and control but need a cost-effective way to scale operations.
  • It allows organizations more data control and scalability, letting them adjust workloads as business and IT service demands change.

Disadvantages of Hybrid Cloud

  • Cloud environments are complex, and you might violate compliance rules if you’re not careful.
  • Hybrid cloud usage by third-party providers puts your organization in danger of cyberattacks on its central server.
  • A hybrid cloud is expensive due to the investment, maintenance, and skill required for on-premises hardware and private cloud components.

Community Cloud

A community cloud is a computing infrastructure that facilitates data sharing across multiple entities. It can be owned and operated by a community organization, a third party, or both.

Advantages of Community Cloud

  • Customers can choose their data protection preferences.
  • Organizations share cloud computing resources, saving them money.
  • The community cloud is flexible, scalable, and works for every user.
  • All cloud-based assets, including infrastructure and services, can be pooled and shared among businesses.
  • The IT department will have less to do since the data, apps, and systems are in the cloud and thus need less management.

Disadvantages of Community Cloud
