Evolution of Cloud Computing -:
· Cloud computing originated in the 1960s with mainframe computing and time-sharing systems that allowed multiple users to access a central computing system.
· In the 1990s, telecom companies began offering dedicated point-to-point data circuits for connecting customer sites to 3rd party data centers. This was an early form of cloud computing.
· In the 2000s, Amazon pioneered the modern cloud computing model by launching Amazon Web Services (AWS) to provide on-demand cloud services.
· Over the past decade, cloud computing has grown exponentially with the rise of public cloud providers like Microsoft Azure, Google Cloud Platform, and more.
Overview of Cloud Computing -:
There are some overview point of cloud computing are -:
§ Cloud computing provides on-demand access to shared computing resources like servers, storage, databases, networking, software, analytics etc over the internet.
§ Resources are rapidly provisioned via virtualization and delivered as a service.
§ Users pay only for what they use/consume following a pay-as-you-go model.
Key Characteristics -:
There are some point characteristics of cloud computing are -:
v On-demand self-service - Users can provision resources without human interaction from the service provider.
v Broad network access - Services are accessible over the internet from anywhere.
v Resource pooling - Provider's computing resources are pooled to serve multiple consumers.
v Rapid elasticity - Capabilities can scale rapidly outward and inward commensurate with demand.
v Measured service - Resource usage is monitored, controlled, reported for transparency.
Key Applications -:
