Cloud Concepts

  • Solid state Drice(SSD)

  • Software as a Service(SaaS)
    The software is already pre-configured and the user isn’t deeply involved in the cloud configuration

  • Infrasture as a service(IaaS)
    You’re hosting your own services in the cloud. You need to decide how you want the infrastruture to look, depending on what you want to run on ot

  • Regions
    a geographical location containing a number of data centers

  • zone

  • if one of them fails for some reason, the others are still available and services can be migrated without visibly affecting users.

  • Public

  • Private

  • Hybrid

  • Public cloud
    Cloud services provided to you by a third party

  • Private cloud
    When your company owns the services and the rest of your infrasture - whether on-site or in a remote data center

  • Hybrid Cloud
    A mixture of both public and private clouds

Typical Cloud Infrastrure Setup

  • Load Balancer
    Ensures that each VM receives a balanced number of queries

  • autoscaling
    It allows the service to increase or reduce capacity as needed, while the service owner only pays for the cost of the machines that are in use at any given time
