Cloud Deployment Models

public - systems and users interact with devices, such as the internet. google microcoft, amazaon. public cluds provide a quick and cost effective way.

private - systems and users only have access with other devices inside the same cloud. A private cloud i

hybrid - combines both private and public cloud options.

cummunicty - collaborative effort where infrastructure is shared between several different orginizations.

Multi- Tenancy - allows customers to share computing resources in a public or private cloud. Assigns a particulare resource to a single orginization. Single - genancy solutions.

Cloud Deployment Models

Public Cloud

  • Resources delivered over the public Internet.
  • Owned and operated by third-party providers (AWS, Microsoft Azure, Google Cloud).
  • Pros: Cost-effective, scalable, quick to deploy.
  • Cons: Less control, shared infrastructure.

Private Cloud

  • Cloud infrastructure dedicated to one organization.
  • Can be on-premises or hosted by a third party.
  • Pros: More control, security, compliance.
  • Cons: Higher cost, less scalability than public cloud.

Hybrid Cloud

  • Mix of public + private.
  • Example: company uses private cloud for sensitive data and public cloud for web apps.
  • Pros: Flexibility, balance of cost and security.
  • Cons: More complex management.

Community Cloud

  • Infrastructure shared by multiple organizations with similar needs (e.g., universities, healthcare providers, government agencies).
  • Pros: Cost sharing, collaboration.
  • Cons: Limited flexibility, still shared.

Multi-Tenancy vs Single-Tenancy

  • Multi-Tenancy:
    • Many customers share the same computing resources (VMs, storage).
    • Each customer logically isolated.
    • Example: AWS public cloud.
  • Single-Tenancy:
    • One customer gets dedicated hardware/resources.
    • Example: Private cloud, or dedicated instances in public cloud.

✅ Exam Must-Knows

  • Public = cheapest, fastest.
  • Private = most secure, most expensive.
  • Hybrid = best of both.
  • Community = multiple orgs share for common goals.
  • Multi-Tenancy = shared resources (most clouds).
  • Single-Tenancy = dedicated resources.
