Types of Cloud Computing

Public Cloud

• 🔧 Cloud platform that's available to the general public
  • Customers can access and manage via the public internet
• Biggest public cloud providers:
  • Amazon AWS
  • Microsoft Azure
  • Google Cloud

Multi-Cloud

• 🔧 Use multiple cloud environments to deploy your app
• Examples:
  • Hosting part of your app architecture in one cloud & another part in another cloud
  • Mirrored Cloud → host the full app architecture in two different clouds e.g. AWS & Azure
    • If app fails in one cloud, the other cloud is still available
• 💡 Suggestion: do NOT use single pane interfaces to manage multi-cloud!!
  • It abstracts away from the vendor
    • Won't know which features and advantages belong to which vendor
  • Only the common set of features/products between vendors is displayed
    • Won't see vendor-exclusive features/products

Private Cloud

• 🔧 On-premises cloud platform dedicated to a private business
• Biggest public cloud providers also offer on-premises deployments:
  • AWS Outposts
  • Azure Stack
  • Google Anthos
• ‼️ Private cloud platforms must still meet the 5 characteristics of cloud computing in order to be considered a cloud platform!!
  • Having on-premises infrastructure like VMWare, XenServer is very different to having an on-premises private cloud platform!

Hybrid Cloud

• 🔧 Use private cloud + public cloud cooperating together as a single environment
  • ❗ Same tooling, same processes & same interfaces are used to interact with both public & private components!
• ‼️ Using public cloud with your own equipment on-premises is considered as hybrid environment or hybrid NWing, NOT hybrid cloud!!
  • In order to count as hybrid cloud, it must be both public cloud and private cloud
