QUICK TIPS & HOWTO GUIDES

What is The 3 4 5 Rule of Cloud Computing?

The 3-4-5 rule of cloud computing is a framework developed by the National Institute of Standards and Technology (NIST) to help understand the key concepts of cloud computing. It breaks down cloud computing into three main categories:

  • 3 Service Models: This refers to the different ways you can access and use cloud resources. These models are:
    • Software as a Service (SaaS) - You rent access to software applications that run on the cloud provider's infrastructure.
    • Platform as a Service (PaaS) - You rent access to a platform for developing, deploying, and managing your own applications.
    • Infrastructure as a Service (IaaS) - You rent access to computing resources like servers, storage, and networking.
  • 4 Deployment Models: This refers to the different locations where your cloud resources can be deployed. These models are:
    • Public Cloud - Resources are shared among multiple users over the public internet.
    • Private Cloud - Resources are dedicated to a single organisation and are not shared with others.
    • Community Cloud - Resources are shared among a specific group of organisations with common interests.
    • Hybrid Cloud - Combines elements of two or more deployment models, such as a public cloud and a private cloud.
  • 5 Essential Characteristics: These are the key features that define cloud computing. These characteristics are:
    • On-demand self-service - You can provision and configure cloud resources without needing interaction with a service provider.
    • Broad network access - Cloud resources are available over the network and can be accessed from anywhere with an internet connection.
    • Resource pooling - The provider's computing resources are pooled to serve multiple customers.
    • Rapid elasticity - You can quickly and easily scale resources up or down to meet your changing needs.
    • Measured service - Cloud resources are metered and you only pay for what you use.

By understanding the 3-4-5 rule, you can gain a better understanding of the different options available in cloud computing and choose the best solution for your needs.
