Cloud Computing is the on-demand delivery of computing power, databases, storage, applications, and other IT resources through a cloud services platform over the Internet, using a pay-as-you-go pricing model.
Cloud computing is an alternative to on-premise data centers, servers, and hardware management. It provides a vendor who handles all hardware components and maintenance.
Amazon Web Services (AWS)
Microsoft Azure
Google Cloud Platform (GCP)
Alibaba Cloud
Oracle, VMware, IBM, Rackspace, Digital Ocean, CloudSigma, NetApp, etc
On-demand self-service: Users can provision computing capabilities as needed automatically without requiring human intervention.
Broad Network Access: Capabilities are available over the network and accessed through standard mechanisms.
Scalability: Resources can be elastically provisioned and released to scale rapidly outward and inward commensurate with demand.
Resource Pooling: Using a multi-tenant model, the provider’s computing resources are pooled to serve multiple consumers.
Measured Services: Cloud systems automatically control and optimize resource use by leveraging a metering capability.
Public Cloud: These clouds are owned and managed by third-party cloud providers and are responsible for managing their infrastructure.
Private Cloud: These clouds are strictly used inside a single business. These may be present on-premise at the organization’s site or may be hosted by a third party.
Hybrid Cloud: These clouds are a combination of both public and private clouds and are maintained together using a set of rules that defines sharing of resources with different parties.
IaaS (Infrastructure as a Service): In IAAS, we can rent the IT infrastructure such as storage, server, network, virtualization, and operating system.
PaaS (Platform as a Service): PASS provides a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications.
SaaS (Software as a Service): SaaS allows users to connect to and use cloud-based apps over the Internet. Users connect to the application over the internet, usually with a web browser on their phone, tablet, or PC.
Cost Effective: Reduces cost for hardware infrastructure.
Speed: Provides resources within minutes and with high throughput.
Flexibility & Scalability: Resources can be increased or decreased according to the current requirement.
Productivity: Provides resources using less effort and with ease.
Reliability: Provides backup and recovery of resources with increased fault tolerance.
Security: Applies policies for data confidentiality, integrity, and availability.
