Businesses often hesitate in choosing Cloud Computing or Cloud Computing – based services that best suit the type and scale of business. Below will be explained more deeply about the types of Cloud Computing services in the business world.

Before getting to know the type of service, you should first understand its definition. Cloud Computing is an information technology system service for users that functions to facilitate organizations in their activities. This service is used flexibly with large-scale virtual servers.

Cloud Type According to Reach

Based on the nature of service coverage, Cloud Computing is divided into four types of services:

1. Public Cloud

Public Cloud type is the most common form of Cloud Computing . The use of services is intended purely for the public with a payment model according to usage. Customers, both individuals and companies, can access services provided by providers through the internet.

Later, computing resources such as applications, data storage systems, and networks that are accessed share with many different users.

Currently, this type of Public Cloud service is used by many companies because vendors have infrastructure that has been equipped with large capacity data centers, such as Google, Microsoft, and Amazon.

This allows users to freely determine the resources they want to rent and pay according to the usage.

In terms of security, you can say that Public Cloud places a high priority on security. So, even if they are in the same cloud environment , one user cannot peek at another user’s data.

2. Private Cloud

Private Cloud is a service designed to meet the needs of certain organizations or companies.

Private Cloud service infrastructure is managed and operated only for groups that are generally large-scale and have the ability to have their own cloud . In terms of location, Private Cloud can be in the position of on site or off site .

In principle, the Private Cloud service cannot be accessed publicly and is open like a Public Cloud . But it can only be accessed by internal company.

The company has control over the implementation of the cloud , both hardware, networks, operating systems, and other software used to create the cloud .

3. Community Cloud

Community Cloud is a cloud infrastructure that is shared by several organizations that have the same interests, and needs the same level of security.

This type of computing is used exclusively based on points of consideration of similarity. For example, the same security needs, the same mission and policies, or similar compliance considerations.

The cloud may be owned and managed by one or more organizations in the community. Can also be owned by third parties or a combination of the organization and third parties.

4. Hybrid Cloud

Cloud infrastructure available on Hybrid Cloud is a combination of other types of cloud . Even though the entities remain independent, there is technology that enables data portability and applications between the cloud to be connected.

In essence, Hybrid Cloud is a composition of two or more infrastructure, both Public Cloud, Private Cloud , and Community Cloud .

Cloud Type By Service Type

Based on the type of service, Cloud Computing is also divided into four types of cloud :

1. Platform as a Service (PaaS)

Platform as a Service (PaaS) is a cloud -based service by renting hardware , operating systems, storage , and network capacity via the internet. Users can rent virtual servers and services to run web -based software that has been developed. In addition, users can also test web -based software that is being developed.

Typically, PaaS is a framework that is used by developers to focus on building or creating software. By using PaaS, users can obtain resources to create software without having to buy the hardware needed. Examples of PaaS that are already available in the world include: Google App Engine, Windows Azure, Amazon Web Service Elastic Beanstalk, Stratos Apache, and OpenShift.

2. Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) is a cloud computing infrastructure service in the form of a package of virtual computer hardware devices , along with internet networks, bandwidth , and IP address support. There is an online guarantee in real time and security within the ‘scope’ of a IaaS service unit.

Service providers commonly called vendors or IaaS providers usually provide various infrastructure specifications, both CPU, RAM and Data Storage in virtual form without an operating system. Examples of Iaas include, Cisco which provides basic features of telephone solutions and Biznet GIO Cloud as a virtual data center for corporations.

3. Data-Storage as a Service (DaaS)

Data-Storage as a Service (DaaS) is a cloud service with a model of providing data storage system facilities remotely and can access them anytime and from anywhere. In essence, users only need to pay fees according to the size of the resource used.

Examples of commercial industries that provide DaaS services are EMC Storage Managed Service (SMS), and Google Cloud Data store.

4. Software as a Service (SaaS)

Software as a Service (SaaS) is a service that refers to software ( software ) based cloud via online through the internet and can be purchased on a subscription basis. The application is available in the form of subscriptions according to user requirements or on-demand . So, users no longer need to buy licenses and install applications, but simply pay fees according to usage.

This model is one of the most commonly used cloud services by companies to build and develop businesses because it is easily managed and very affordable. Users do not need to download and install on each device to spread it to the whole team. This service is very useful for teams that work with separate spaces and distances.
