Introduction to Types of Cloud Computing
Service offered via the internet are generalized as cloud computing and is categorized as IaaS, PaaS, FaaS, and SaaS, it is mainly divided into two types I,e, Deployment and Service models where the deployment model consists of the cloud computing services like Public Cloud, Private Cloud, Private and Hybrid which is used for applications like blog hosting, creation of a fresh application, Video, and Audio stream, etc.
Types of Cloud Computing
There are mainly two types of Cloud Computing which are as follows:
- Deployment Model
- Service Model
The following kinds of cloud computing may be available based on the three types of deployment model:
- Public
- Community Cloud
- Private
- Hybrid
1. Public Cloud
The public cloud is described as computing services provided through the public internet by third-party suppliers, making them accessible to those who want to use them or buy them. It can be free or on-demand for customers to pay for the cycles, storage, or bandwidth they consume per usage.
Example: Sun Cloud, AWS, Microsoft Azure
2. Community Cloud
A particular group of customers from organizations with shared issues can only use cloud infrastructure. It may be owned, operated, managed, and run by one or more of the communal organizations, a third party or a mixture of them.
3. Private Cloud
A private cloud is a cloud computing system in which IT services are supplied for the specialized use of one organization over private IT facilities. A single organization operates the cloud infrastructure only. It can be run on-site or off-site by the organization or a third party. Private cloud terms are often employed interchangeably with the virtual private cloud (VPC). Technically speaking, a VPC is a private cloud that uses the infrastructure of a third-party cloud provider, while an inner cloud is enforced.
Example: AWS, VMware
4. Hybrid Cloud
A hybrid cloud is a computer environment that incorporates a government and private cloud to share information and apps. Organizations achieve flexibility and the computer capacity of a government cloud for fundamental and insensitive computing functions whilst safe behind a corporate firewall for business-critical apps and information.
Example:
When delicate data is engaged, Federal agencies opt for personal clouds.
The following kinds of cloud computing may be available depending on the type of service model:

What is IaaS?
IaaS is a cloud computing model in which companies’ external cloud providers provide and manage virtualized infrastructure for businesses. With IaaS, businesses can outsource Internet-based storage, servers, data centers, and network elements with the same functionality as local infrastructure. Some examples of IaaS’s extensive use include automated policies such as support, clustering, inner networking, restoration, tracking, hosting the site, etc. The provider is responsible for server and storage building, networking of firewalls/security, and physical data centers. The supplier is in charge of server and storage construction, firewall networking, and safety and physical information centers.
What is Paas?
PaaS builds on IaaS. Cloud vendors are providing computing resources here to create and test apps, including cloud and hardware infrastructure parts, such as middleware and operating systems. In addition to constructing and keeping the required equipment, the PaaS environment allows cloud users to install and house information sets, development instruments, and company assessment software. Some of the main players with a PayPal system include CloudBees, Salesforce.com, Engine, Heroku, Google App, Bluemix.
What is Saas?
Software as a service (SaaS) is a distribution system of software where a third-party supplier hosts and provides apps to clients over the Internet. The SaaS host application management model is similar to ASP, in which the provider hosts the software of customers and delivers it over the internet to approved end-users. The provider provides network-based customers with a unique copy of an application that was specially designed by a provider for the SaaS distribution in the software on-demand SaaS model. The source code for the Application is the same for all clients and is implemented by all clients when fresh functions or functionalities are developed.
What is Faas?
Faas stands for the Functions as a server. FaaS brings another layer of PaaS abstraction, making designers fully insulated from all the things under their software in the stack. Installation blocks of code in narrow functionality and set them to be activated by a certain event rather than the hazards associated with virtual servers, containers, and application runtimes. Until an event happens, FaaS applications don’t consume IaaS resources, lowering the charges.
Uses of Cloud Computing
While you may not be aware that you are now using cloud computing, most of us use an internet service to send e-mail, edit records, watch films, etc. Cloud computing probably makes everything possible behind the scenes. Today, many organizations, from small start-ups to public organizations, are using the following technology.
- Create fresh applications and services, save, backup, and retrieve information.
- Blogs and Hosting Websites.
- Video And Audio Stream.
- Provide software services on request.
