Cloud computing, in its most basic definition, is a shared pool of powerful computing resources delivering the home and business various kinds of services including application access and storage, management and processing of data without the need for a physical computer. With cloud computing you pay only for the services you use, providing the user a reduction in unnecessary infrastructure costs and back-end savings by creating an economy of scale.
What are the benefits of cloud computing?
Similar to an electricity or gas utility, with cloud services you only pay for what you use and management of hardware and software is managed by technology vendors such as Microsoft or AWS. Cloud-based applications such as productivity, accounting, and marketing, can be running in days with the user in any location simply opening a web browser, logging in and away you go.
- Cost: Cloud computing costs a lot less to use than operating your infrastructure since you don’t have to buy physical hardware.
- Scalability: If you want to upgrade your service, you can do so on the fly at the click of a button without much hassle. Compare that to buying new hardware and swapping it out everytime you want to upgrade.
- Security: Most cloud service providers have extensive guidelines and dedicated teams for managing the security and integrity of the data and associated operations.
- Backup and Redundancy: There are multiple data centres located all around the world even if one goes down there are backup options so that your work or business isn’t affected.
- Efficiency: Cloud, in terms of both productivity and speed, is unmatched by physical servers. Unlike the latter where you have to think about hardware setup, software loading and IT management chores, in the cloud, you can effortlessly deploy services on demand without any need for prior provisioning so you can focus on your business goals.
- Performance: Data centres are equipped with the latest and greatest hardware and software with reduced latencies and greater economies of scale to provide cloud users with the best and most secure IT platforms.
Thus accessibility, affordability and above all efficiency, the key aspects of cloud computing which make it suitable for you, as well as everyone else’s needs.
What are the types of cloud?
Public Cloud: These are cloud services provided by a third party who delivers computing resources and other kinds of services over the internet. The data centres and other infrastructure is wholly owned by the cloud service provider. Microsoft’s Azure platform and Amazon Web Services are both provide public cloud platforms.
Private Cloud: It refers to the computing resources dedicated to a single organization only and as the name suggests for their own use and the infrastructure is kept on a private network.
Hybrid Cloud: This, as the name aptly suggests, is a combination of the above two using technologies that allow data and services to be shared between the private and public cloud so as to tailor the experience to the customer’s individual needs. It gives you a lot of legroom to customise or change things to your need.
