Types of Cloud Computing


Types of Cloud Computing

Businesses looking for convenient ways to access and store their data may want to think about cloud computing services. Clouds can assist businesses in lowering their IT operations expenses, enhancing cybersecurity, and speeding up computing. It's crucial to initially comprehend the many cloud computing configurations available to you if you're thinking of integrating cloud computing services into your business. This article talks all about cloud computing.

What is Cloud Computing?

Cloud computing is a technology that offers services to people or organisations over the internet. Businesses frequently use the cloud to conveniently store, move, and update their corporate data. The cloud can make it simpler for businesses to permit their employees to access corporate resources from a range of places and devices because users access their cloud services online. In a virtual setting, clouds can also offer a wide range of additional services, such as servers, databases, software, and networks.

To free up space on their office grounds, businesses can use cloud computing in place of or in addition to traditional servers. For businesses that routinely manage huge or sophisticated volumes of data, cloud computing may be a more cost-effective solution.

Types of Cloud Computing

Here is a list of the 5 different types of cloud computing:

Public Cloud

Public clouds are cloud computing environments that are frequently built using IT infrastructure that is not the end user's. Alibaba Cloud, Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure are a few of the biggest public cloud service providers.

Public clouds in the past have always operated off-site, but today's public cloud providers have begun to provide cloud services on clients' on-site data centres. Locational and ownership distinctions are now irrelevant as a result.

When the environments are divided and dispersed to several tenants, all clouds become public clouds. Since some cloud providers (like the Massachusetts Open Cloud) permit tenants to utilise their clouds for free, fee structures are no longer a need for public clouds. It is also possible to abstract and resell the bare-metal IT infrastructure used by public cloud providers as IaaS, or to build and resell a cloud platform as PaaS.

Private Cloud

A private cloud is a cloud environment that is completely dedicated to one end user or group, typically running behind that user's or group's firewall. When the underlying IT infrastructure is devoted to a single client with totally segregated access, all clouds become private clouds.

However, private clouds are no longer required to be powered by on-site IT equipment. Now that businesses are constructing private clouds in off-site, rented data centres operated by vendors, all standards governing location and ownership are irrelevant. Several private cloud subtypes have also resulted from this, including:

Managed private clouds

A third-party provider deploys, configures, and manages a private cloud that customers build and utilise. Enterprises with understaffed or underqualified IT teams can improve the quality of their private cloud services and infrastructure by using managed private clouds as a cloud delivery option.

Dedicated clouds

A cloud inside of a cloud. A dedicated cloud can be found on either a private or public cloud, such as Red Hat OpenShift® Dedicated. For instance, the private cloud of the company might contain a separate cloud for the accounting division.

Hybrid Cloud

A hybrid cloud is an IT environment made up of several environments that appear to be connected by LANs, WANs, VPNs, and/or APIs to form a single, unified environment.

Depending on who you ask, the criteria for hybrid clouds might vary and their characteristics can be complicated. For instance, a hybrid cloud would require:

  • a minimum of one public cloud and one private cloud
  • at least two private clouds
  • at least two public clouds
  • a virtual or bare-metal setup coupled with at least one public or private cloud

However, when apps may move in and out of many distinct—yet connected—environments, every IT system turns into a hybrid cloud. These environments must be derived from centralised IT resources that can scale as needed, at the very least. And a platform for integrated management and orchestration must be used to manage each of those environments as a single environment.


A multicloud architecture consists of multiple cloud services from various public or private cloud vendors. Although not all multiclouds are hybrid clouds, all hybrid clouds are multiclouds. When numerous clouds are linked together by some kind of integration, they become hybrid clouds.

An environment with many clouds may exist accidentally or on purpose (to better protect sensitive data or provide redundant storage for improved disaster recovery) (usually the result of shadow IT). In any case, businesses who want to enhance security and performance through a broadened portfolio of environments are increasingly likely to have numerous clouds.

High Performance Computing (HPC) Cloud

Specialized cloud services are offered by HPC clouds for supercomputers and other high-performance computing hardware. Supercomputers are employed by some businesses to carry out difficult computational tasks, such modelling chemical compounds or making weather predictions. An HPC cloud provides sufficient data storage and server power to support the continued efficient operation of supercomputers while supplying enterprises with the services they require.

Cloud Computing Models

This section talks about the four types of cloud computing models:

Infrastructure as a Service (IaaS)

The fundamental components of cloud computing, also known as IaaS, include access to networking capabilities, machines (virtual or on dedicated hardware), and data storage space. With the most flexibility and management control over your IT resources, Infrastructure as a Service is most comparable to the current IT resources that many IT departments and developers are accustomed to today.

Platform as a Service (PaaS)

Platforms as a Service allow you to concentrate on the deployment and administration of your applications by removing the need for companies to manage the underlying infrastructure (often hardware and operating systems). As a result, you can run your application more efficiently as you won't have to deal about things like resource acquisition, capacity planning, software maintenance, patching, or any other undifferentiated heavy lifting.

Software as a Service (SaaS)

With software as a service (SaaS), the service provider gives you a finished product that is operated and managed on your behalf. The majority of the time when software as a service is mentioned, end-user applications are meant. With a SaaS solution, you only need to consider how you will utilise that specific piece of software; you do not need to consider how the service is managed or how the underlying infrastructure is maintained. Web-based email is a typical example of a SaaS application since it allows you to send and receive emails without having to manage feature updates or upkeep for the servers and operating systems that the email programme is using.

How to Choose a Cloud Computing Model

The following details will assist you in selecting the ideal cloud computing model:

Analyze your Budget

Think about the cost of installing or upgrading your cloud computing services for your company. Public clouds are common examples of cloud computing deployment systems and services that provide shared resources or limited storage and performance capacities. However, it might be worthwhile spending for a more expensive cloud service system or architecture if your firm requires more privacy or greater control over some of your cloud resources.

Think about your computer needs

Analyze the computer requirements for your firm, including performance speed, cybersecurity, agility, and connection. Different cloud architectures and services could work better for some firms than others. A serverless or PaaS cloud solution, for instance, could offer you the agility you need to test, create, and launch new apps if your company develops software.

Review your compliance requirements

Consider the type of cloud you require to meet regulatory compliance requirements. It's crucial to become familiar with a cloud provider's security methods and procedures because some businesses have rigorous restrictions about how they must handle or store data. A cloud computing system that offers improved security protections, like a private or multi-cloud arrangement, may be necessary for organisations that frequently handle sensitive or confidential data.
