Cloud Computing

Cloud computing is the delivery of computing services—such as servers, storage, databases, networking, software, analytics, and intelligence—over the internet (the “cloud”) to offer faster innovation, flexible resources, and economies of scale. Instead of owning and maintaining physical data centers and servers, businesses and individuals can access these resources on-demand from a cloud provider, paying only for the services they us

Types of Cloud Services :-

  • Infrastructure as a Service (IaaS) :- Provides virtualized computing resources over the internet (e.g., AWS EC2, Google Compute Engine).
  • Platform as a Service (PaaS) :- Offers hardware and software tools over the internet, allowing developers to build applications (e.g., Google App Engine, Microsoft Azure).
  • Software as a Service (SaaS) :- Delivers software applications over the internet (e.g., Google Workspace, Salesforce).

Types of Cloud Deployment Models :-

  • Public Cloud :- Shared resources available to multiple users over the internet (e.g., AWS, Microsoft Azure).
  • Private Cloud :- Dedicated infrastructure for a single organization, either on-premises or hosted by a third party.
  • Hybrid Cloud :- Combines public and private clouds, allowing data and applications to be shared between them.
  • Multi-Cloud :- Utilizes services from multiple cloud providers to avoid vendor lock-in and optimize resources.

Key Characteristics of Cloud Computing :-

  • On-Demand Self-Service :- Users can provision resources as needed without requiring human interaction with the service provider.
  • Broad Network Access :- Services are available over the internet and can be accessed from a wide range of devices, including smartphones, tablets, and laptops.
  • Resource Pooling :- Providers use a multi-tenant model to serve multiple customers, dynamically allocating resources based on demand.
  • Scalability and Elasticity :-Resources can be scaled up or down quickly, based on user needs.
  • Measured Service :- Cloud systems automatically control and optimize resource use by leveraging a metering capability, so you only pay for what you use.
