Understanding Cloud Computing

Before diving into preparation, it’s important to have a solid understanding of what cloud computing is. At its core, cloud computing involves delivering computing services—such as servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”). This allows for flexible resources, faster innovation, and economies of scale.

Key Areas of Cloud Computing

1. Cloud Service Models

   • Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
   • Platform as a Service (PaaS): Offers hardware and software tools over the internet, typically for application development.
   • Software as a Service (SaaS): Delivers software applications over the internet, on a subscription basis.

2. Cloud Deployment Models

   • Public Cloud: Services are delivered over the public internet and shared across organizations.
   • Private Cloud: Services are maintained on a private network, used by a single organization.
   • Hybrid Cloud: Combines public and private clouds, allowing data and applications to be shared between them.
