What is cloud computing?
Cloud computing refers to the on-time delivery of on-demand computing services such as processing, storage, and access to data and programs over the internet instead of the computer’s hard drive.
Cloud computing will take care of services such as databases, software, servers, storage, networking, analytics, and intelligence. Computer clouding enhances quick innovation, economies of scale, and flexible resources.
How does cloud computing work?
Companies and organizations no longer need to incur further expenses to own data centers and computing infrastructure. Instead, they only need to hire the services of a cloud computing provider for all their computing requirements.
The most significant benefit of cloud computing a firm can do away with IT infrastructure and its costs. A further cost is reduced because you only pay for what you use when you use it.
Types of cloud computing
There are different types of clouding. The type of cloud computing depends on the unique needs of a client. Further, different forms, types, models, and are customized to meet the specific solution for an entity that allows you to choose the extent of control you can have over your information.
This is a rapidly growing field in information and technology. As of now, there are four main types of cloud computing deployment models. The models tend to pile on top of one another and are also referred to as cloud computing stacks.
- Infrastructure as-a-service (IaaS)
This is the most basic category of cloud computing services. It offers internet access and storage and computing power. Once IaaS is installed, it allows you to rent IT infrastructure from a cloud computing service provider such as cloud it services. The package includes network, storage, servers, and virtual devices, and respective operating systems.
- Platform as a service (Paas)
Paas makes it easy for users to create and develop mobile applications, web over the internet. Paas offers an on-demand platform for innovative development and testing of software applications.
Developers do not have to set up or manage servers, storage, data, networks, and database infrastructure required for software application development.
- Software as a service (SaaS)
Software as a service is a cloud computing service for developing and delivering web-based applications over the internet. The developer accesses the internet with a web browser on their smart electronic devices such as a phone or tablet. Saas works on an on-demand subscription basis.
The cloud computing service provider hosts the software application and manages it too. The provider also handles all the software underlying infrastructures and runs maintenance such as security patching and software upgrading.
Serverless computing
Serverless computing overlaps with Platform as a service (PaaS). Serverless computing builds on app functionality without having to continually manage the servers and the infrastructure required.
The cloud computing provider offers the setup, handles capacity planning, and provides server management services. Serverless cloud computing is event-driven. Therefore, it uses resources when a trigger occurs or a specified function is required.
Uses of Cloud Computing
You might be using cloud computing at your workplace even if you’re not aware. How is that possible? The email you sent recently may be using clouding.
Other services that could be using cloud computing behind the scenes include editing documents, watching movies, playing music, storing pictures, and other files.
Cloud computing is barely a decade old, though several entities such as government agencies, global corporations, startups, profit, and non-profit organizations have embraced it for all sorts of benefits.
- Cost-effective – Cloud computing significantly cuts physical hardware investment costs because the service provider buys and maintains all the equipment needed. The firm only pays for the cloud computing services they’ve used per time.
- Enhanced storage – An organization using cloud computing services has an edge over its competitors. One can access the latest application software soon they’re available in the market without incurring extra cost and spending much time and effort to stay updated.
- High speed – Computer clouding allow users to access to the internet and other services very fast. Within minutes and fewer clicks, one can deploy the services they need. It allows one to do more in a relatively short time.
- Mobility – Computer clouding allows resident and remote employees to access their desired services. Clouding accessibility is possible regardless of its proximity. The only requirement is reliable internet connectivity.
- Unlimited storage space- Clouding has no limit on storage space. You only need to add a minimal monthly fee to your provider, for the expansion of your storage capacity.
Other benefits include advanced online security, quick, effective virtualization, enhanced reliability, low-cost software among other benefits.
