What is cloud computing?(JNNC Technologies)

Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources — everything from applications to data centers — over the internet on a pay-for-use basis.

• Elastic resources — Scale up or down quickly and easily to meet demand
• Metered service so you only pay for what you use
• Self service — All the IT resources you need with self-service access
• Cloud-based applications — or software as a service — run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the internet and, usually, a web browser.
  The benefits of SaaS
• You can sign up and rapidly start using innovative business apps
• Apps and data are accessible from any connected computer
• No data is lost if your computer breaks, as data is in the cloud
• The service is able to dynamically scale to usage needs
• Platform as a service provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications — without the cost and complexity of buying and managing the underlying hardware, software, provisioning, and hosting.
  The benefits of PaaS
• Develop applications and get to market faster
• Deploy new web applications to the cloud in minutes
• Reduce complexity with middleware as a service
• Infrastructure as a service provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.
  The benefits of IaaS
  • No need to invest in your own hardware
  • Infrastructure scales on demand to support dynamic workloads
  • Flexible, innovative services available on demand
