Cloud refers to network or Internet. Further advancement of technology has provided an opportunity to store and process all data in the “cloud”, bringing about optimization and efficiency in all sectors of the community.

Cloud Computing refers to manipulating, configuring, and accessing applications online. It offers online data storage, infrastructure, and applications. It is both a combination of software and hardware-based computing resources delivered as a network service.
There are two working models in relation to Cloud Computing. The first one, Cloud Deployment Models, explains how the resources are provided in the cloud. Its main categories are the following.
- Public Cloud - Allows the accessibility of systems & services to its clients/users. Examples of these are AccuBooks, Google, Microsoft, and Amazon.
- Private Cloud - Allows systems and services to be accessible within an organization and offers increased security because of its private nature. Examples are Dell and IBM.
- Hybrid Cloud – It is a mixture of private and public. However, the critical activities are performed using the private cloud while the non-critical activities are performed using the public cloud. Known examples of this are Netflix, Airbnb, and Uber.
- Community Cloud - the cloud setup is shared manually among different organizations that belong to the same community or area. Agencies can use this model to test applications with high-end security needs rather than using a public cloud.
The second working model is the Cloud Service Models. It describes up to what extent resources like storage, services, networks, applications, servers, and many more are managed by the company or a cloud service provider. Here are the types:
- Infrastructure as a Service (IaaS) – It is where users get access to basic computing infrastructure, commonly used by IT administrators. Companies manage the data, runtime, middleware, application, and the operating system while the rest is handled by the cloud provider. It gives control over the hardware that runs the applications (virtual machines, servers, storage, load, balancers, networks, and operating systems).
- Platform as a Service (PaaS) - PaaS only requires you to handle the application and the data since users are given software and hardware automatically. Control is given over the hardware that runs the applications (Execution runtime, database, web server, development tools).
- Software as a Service (SaaS) - Provides a complete product that is run and managed by the cloud service provider. It is the most used cloud application service and is becoming a dominant way for organizations to access software applications.
