Cloud Computing

Private, Public, Multi-Cloud, Hybrid Cloud

Cloud Computing is a model of delivering computing services over the internet, where resources such as servers, storage, databases, software, and applications are provided as a service to users on-demand. Instead of having to manage and maintain their own hardware and software, users can access these resources on a pay-as-you-go basis, allowing for greater flexibility, scalability, and cost savings.

The main characteristics of Cloud Computing are:

On-demand self-service: Users can provision and de-provision resources as needed, without requiring human intervention.
Broad network access: Resources are accessible over the internet, from any device, anywhere in the world.
Resource pooling: Resources are pooled together to provide a multi-tenant environment, where resources can be dynamically allocated and re-allocated based on demand.
Rapid elasticity: Resources can be quickly scaled up or down to match changing business needs.
Measured service: Users only pay for the resources they consume, with pricing based on usage.

Cloud Computing offers several benefits, including:

Scalability: Resources can be quickly scaled up or down to match changing business needs.
Cost savings: Reduced capital expenditures, operating expenses, and total cost of ownership.
Increased flexibility: Access to resources from anywhere, on any device, at any time.
Reliability: Built-in redundancy, backup, and disaster recovery capabilities ensure high uptime and availability.
Security: Advanced security features, such as encryption, access controls, and monitoring, to protect data and applications.

Cloud Computing deployment models include:

Public Cloud: A third-party provider delivers cloud services over the internet, available to anyone.
Private Cloud: A single organisation operates and manages the cloud infrastructure, solely for their own use.
Hybrid Cloud: A combination of public and private cloud services, allowing for flexibility and scalability.
Community Cloud: A cloud infrastructure shared by multiple organisations with similar interests or goals.
Edge Cloud: A cloud infrastructure located at the edge of the network, closer to users, reducing latency and improving performance.
