Cloud computing refers to the provision of an information technology infrastructure, drivers, middleware, and applications hosted within a data center that can be accessed by the end user over the Internet.
So what is cloud computing in business and what are the main trends of it?
Cloud computing in businesses is typically sold using three models, namely
(IaaS) Infrastructure as a service
It is a model for leasing IT hardware such as servers, data center or network components to IT system administrators or network engineers, saving them the cost of purchasing and building their own internal data center.
Platform as a service (PaaS)
It is a model for providing information technology platforms and is used to allow application developers to create, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with application development and operation.
Software as a service (SaaS)
A model for licensing and offering centrally hosted online software on a subscription basis for businesses and consumers.
Why is cloud computing important for business?
Cloud computing makes it easier, cheaper and faster to run the latest IT structures in any type of company, large or small, and the main benefits are
Substantial cost savings across the company’s IT budget.
The invoices are usually measured by use so IT expenditures shift from one-time capital expenditures to monthly operating expenses providing a cash flow advantage.
Flexibility as companies can rent IT equipment and applications as needed instead of directly purchasing hardware and software assets.
Scalability as computing capabilities such as storage, processing power, or network bandwidth can be increased almost instantly and shrunk again on demand.
IT resources can be accessed by any authorized users on any authorized devices from anywhere authorized using the Internet connection. Businesses benefit from cheaper, faster, and more scalable IT resources in the cloud, and users have a better experience.
