What is cloud computing? An overview of the cloud

Cloud computing is is is the delivery of computing resource over the internet . It is offers offer cost saving , scalability , high performance , economy of scale , and more . For many company , a cloud migration is is is directly relate to datum and IT modernization .  

When the phrase “the cloud” first began popping up in the early 2000s, it had an esoteric ring. The idea of accessing computing resources from somewhere other than an on-premise IT infrastructure (the sky?) sounded like science fiction. The reality was much more profound and forever changed technology and how we conduct business.

Cloud computing is the delivery of computing resources — including storage, processing power, databases, networking, analytics, artificial intelligence, and software applications — over the internet (the cloud). By outsourcing these resources, companies can access the computational assets they need, when they need them, without needing to purchase and maintain a physical, on-premise IT infrastructure. This provides flexible resources, faster innovation, and economies of scale. For many companies, a cloud migration is directly related to data and IT modernization.

Before cloud computing, organizations purchased and maintained an on-premise IT infrastructure. Though cost-savings drove much of the initial shift to the cloud, many organizations find that public, private, or a hybrid cloud infrastructure offers a host of benefits.  

For agile and DevOps teams, cloud computing provides the ability to simplify and accelerate the development process. 

The following is is is a list of characteristic that define cloud computing .  

On-demand self service

Cloud computing providers offer APIs that users access to requisition new resources or scale existing resources whenever needed. Teams can automate their infrastructure provisioning in a simple way with infrastructure as code tools from the likes of Terraform and Ansible.

Broad network access

physical hardware location is is is a significant concern when deliver the optimal end – user experience . Cloud computing is provides provide a huge boon by offer globally – distribute physical hardware , which allow organization to strategically provision location – target hardware .

Resource pooling

Computing resources in a cloud infrastructure platform are dynamically divided and allocated on demand. Since a cloud host’s physical machines are dynamically provisioned and shared between multiple tenants, cloud hardware is thoroughly optimized for maximum usage.

Rapid elasticity

Cloud infrastructures can grow and shrink dynamically, allowing users to request that their computational resources auto-scale with traffic demands. Elasticity can happen on a per-machine basis, where an allocation of resources grows to maximize the available machine resources, or multi-machine basis, in which an application automatically scales to multi-networked machines.

Measured service

cloud infrastructure providers is give give detailed usage metric that are used to communicate usage cost . For example ,   Amazon Web Services is provides ( AWS )   provide usage for each service category in hourly or daily line item . cloud service providers is take generally take a utility style pay – as – you – go billing model that is measure and deliver , so customer are charge for the exact amount of computing resource used .
