What exactly is “cloud computing”, and how does it work?
Cloud computing is a service that can be accessed on demand and has recently gained widespread adoption in business data centres. The Cloud makes it possible for the data centre to function the same way as the Internet, and it enables computing resources to be accessed and shared in the form of virtual resources in a safe and scalable way.
The Cloud provides access to three primary services, each of which can be customised to meet the specific demands that you have for Cloud Computing:
1- Software as a service, also known as SaaS, is a model for distributing software in which a third-party provider hosts applications and makes them available to customers via the Internet. SaaS is an abbreviation for the phrase “software as a service.”
2- Platform as a Service (PaaS) is an all-inclusive development and deployment environment hosted in the Cloud. It consists of resources that enable you to deliver anything from straightforward cloud-based applications to complex cloud-enabled enterprise applications.
3- Infrastructure as a service (IaaS) refers to an instant computing infrastructure that is provisioned and managed through the Internet.
Benefits of cloud computing to smaller businesses?
– Availability at all times The vast majority of cloud service providers are highly dependable in terms of their services; many maintain uptime of 99.99 per cent.
Data and applications are accessible to employees no matter where they are located worldwide, which contributes to increased mobility.
Because companies don’t have to spend significant money on hardware, facilities, utilities, and other aspects of operations, cloud computing is more cost-effective. Companies don’t have to purchase equipment and build and operate a data centre. This frees up capital for the companies.
Cloud computing provides a flexible cost structure, which helps limit exposure during times of economic downturn or business cutbacks (like the ones currently experienced by the energy industry). – you can quickly reduce expenses. – Cloud computing can help limit exposure.
We are collectively having less of an impact on the environment thanks to the reduction in the number of data centres located worldwide and the improvement in the efficiency of their operations. Businesses that collaborate and share their resources are more environmentally responsible.
