[Infographics] How Does Cloud Computing Work? Different Cloud Models Explained

What is Cloud Computing?

The process of storing, managing, and processing data on a network of servers hosted on the internet instead of a local server or a personal computer is known as Cloud Computing. The cloud computing industry is expected to be worth an astounding $ 623.3 billion by 2023.

How it Works

Whenever a user makes a service request, for example, a storage request, database access request, or a computing request, the request is sent to the API gateway. An API gateway is a service provided by the Cloud Provider used to create, publish, maintain, monitor, and secure REST, HTTP, and WebSocket APIs.

It provides a simple interface to a more complex system, that includes the servers and the databases, along with other services. The user can then execute the request and access servers and databases. Hence, through cloud computing, the user can work on their company’s servers from anywhere in the world.

Different Cloud Service Models

Cloud service models are divided into two types, deployment models and service models. A cloud deployment model reflects a particular kind of cloud system, characterized mainly by ownership, size, and access. A service model enables companies to offer services to other companies.

Deployment Models

  •   Private Models: In private models, computing services are provided either over the internet or a private internal network and only to select users.
  •   Public Models: In public models, computing services are provided by third-party providers over the public internet, making them available to anyone who wants to use or purchase them.
  •   Hybrid Models: It is a computing environment that combines a public cloud and a private cloud by allowing data, applications, and services to be shared between them.

Service Models

  •   SaaS (Software as a Service): Software as a service uses the internet to distribute third party vendor-managed software to its customers. Using SaaS apps tends to reduce software ownership costs by removing the need for technical staff to manage software installation, management, and upgrades, as well as reducing the licensing software costs. Some examples are Email, CRM, Collaborative, and ERP.
  •   PaaS (Platform as a Service): It provides certain software with a platform. PaaS provides developers with a framework that they can build on and use to create custom apps. It is used for application development, decision support, web, streaming, etc.
  •   IaaS (Infrastructure as a Service): IaaS is a way to deliver cloud computing infrastructures such as servers, storage, network, and operating systems. Through any cloud computing platform, customers can access those resources. Application development, decision support, web, and streaming are some examples

Cloud computing provides many opportunities for a company: 

1. Comfort & Cost Reduction

It enables you to set up what is essentially a virtual office to give you the flexibility to connect anyplace, any time. With the rising number of web-enabled devices used in today’s business world, it is easier to access the data. If you opt for Cloud Computing for your business, you can save costs by using your cloud computing service provider’s resources, rather than spending on purchasing and maintaining costly systems and hardware.

2. Protection

Cloud-based solutions are held within very secure data centers where physical access is strictly controlled. Vast quantities of computing resources can be provided in minutes, usually with only a few mouse clicks, allowing companies a lot of flexibility.

3. Scalability

Another benefit that Cloud Computing offers is Scalability. Your business can quickly expand or scale down your operation and storage needs, allowing flexibility as your requirements change. Your cloud computing service provider will do this for you, rather than purchasing and installing costly updates yourself. Using the cloud will free up your time, and you can continue to run your company.
