Cloud Computing Definition

In order to provide speedier innovation, flexible resources, and economies of scale, cloud computing refers to the supply of computing services—including processing power, storage, databases, networking, software, analytics, and intelligence—over the internet (also known as “the cloud”. Instead of owning and maintaining physical hardware and infrastructure, users can access computing resources on a pay-as-you-go basis from cloud service providers.

Key characteristics of cloud computing include:

On-Demand Self-Service: Without assistance from the service provider, users are able to provision and manage computer resources as needed.

Broad Network Access: Services are accessible over the network and can be accessed through standard mechanisms by diverse client platforms (e.g., laptops, smartphones, tablets).

Resource Pooling: Multiple clients can be served by a single pool of computing resources, with distinct virtual and physical resources being dynamically assigned and reassigned based on demand.

Rapid Elasticity: Resources can be rapidly provisioned and released to scale in or out based on demand. Users pay only for what they use.

Measured Service: Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts).

Types of Cloud Computing

Infrastructure as a Service (IaaS

Provides virtualized computing resources over the internet. On a pay-per-use basis, users can rent networking infrastructure, storage, and virtual machines.

Examples: Amazon Web Services (AWS) Elastic Compute Cloud (EC2), Microsoft Azure Virtual Machines.

Platform as a Service (PaaS):

Offers a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the underlying infrastructure.

Examples: Google App Engine, Heroku, Microsoft Azure App Service.

Software as a Service (SaaS):

provides software via the internet, saving consumers from having to install, maintain, and manage the programme locally.

Examples: Google Workspace, Microsoft 365, Salesforce.

Function as a Service (FaaS) / Serverless Computing

Allows developers to run individual functions or pieces of code in response to events without managing the underlying server infrastructure.

Examples: AWS Lambda, Azure Functions, Google Cloud Functions.

Storage as a Service

Provides scalable and accessible storage solutions over the internet.

Examples: Amazon S3 (Simple Storage Service), Google Cloud Storage, Microsoft Azure Blob Storage.

Database as a Service (DBaaS)

Offers database management and access over the internet without the need for users to install, configure, and manage databases locally.

Examples: Amazon RDS (Relational Database Service), Google Cloud SQL, Microsoft Azure Cosmos DB.

Container as a Service (CaaS)

Manages and orchestrates containerized applications and services, providing an environment for developing, running, and scaling containerized applications.

Examples: Kubernetes, Amazon ECS (Elastic Container Service).

These Cloud computing course Online Its models provide different levels of abstraction and services, allowing organizations and individuals to choose the most suitable model based on their specific requirements and use cases.

What are cloud services?

Cloud services refer to a broad category of services delivered over the internet by cloud computing providers. These services can encompass a wide range of computing resources, applications, and functionalities that are made available to users and organizations on a pay-as-you-go or subscription basis. Cloud services are often categorized into different models, such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Here are common types of cloud services:
