Hello friends, I am Shivam Sharma, Linux trainer at Grras solution (P) ltd. In this blog I am sharing some basic knowledge about Cloud Computing. I hope that it will help you all to understand that what is cloud computing actually.
What is Cloud Computing?
Cloud computing has been defined by the U.S. National Institute of Standards and Technology (NIST) as â€œ â€¦a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
Characteristics of cloud computing-
ïƒ˜ Global network access
Cloud deployment models-
ïƒ˜ Public cloud is a cloud that is available to the general public, run by a cloud provider.
ïƒ˜ Private cloud is a cloud used by a single organization.
ïƒ˜ Hybrid cloud is a combination of deployment models. The hybrid cloud is often used to expand resources into a public cloud when more computing resources are needed.
Cloud service models-
ïƒ˜ Software as a service (SaaS)
ïƒ˜ Platform as a Service (PaaS)
ïƒ˜ Infrastructure as a Service (IaaS)
