Cloud computing refers to a virtualized form of computing where systems, data and IT infrastructure can be used and accessed remotely through various devices. Cloud technologies allow us to utilise multiple services that require powerful hardware resources, without the need to possess dedicated hardware and IT infrastructure. With the help of cloud architectures, companies and individuals can use essential services for storage, networking, servers, software, etc., from anywhere in the world.
Various businesses are rapidly adopting cloud-driven technologies. This shift has boosted the efficiency as well as productivity of many companies. The different types of cloud computing can be explained with the help of the following parameters:
- Types of virtualization in cloud computing
- Types of clouds in cloud computing
- Types of cloud computing services
- Types of scaling in cloud computing
Read along to know about all the different types of cloud computing in detail.

Types of Virtualization in Cloud Computing
Virtualization is the process of creating digital platforms that emulate servers, computers, operating systems, storage devices, network systems, or other hardware resources. The types of virtualization in cloud computing are stated as follows:
Hardware Virtualization
Hardware virtualization is the system where Virtual Machine Manager is directly installed in a hardware system. It has to control and monitor the hardware processors and memory resources. After the installation of a hardware system, the operating system can be installed in a computer. Hardware virtualization plays a major role in controlling the server platforms.
Operating System Virtualization
Operating system virtualization is the system where Virtual Machine Manager is directly installed in a host operating system rather than installing it in the hardware system. This type of cloud virtualization is mainly used for testing various applications on different operating system platforms.
Server Virtualization
Server virtualization is the system where Virtual Machine Manager is directly installed in a server system. So, server virtualization is mainly used for dividing a single major server into multiple physical servers on the demand by many organisations to balance the load of data and information on the company servers.
Storage Virtualization
Storage virtualization is the system where the grouping of physical storage takes place from various network storage devices. To users, it appears to be a single storage device. Using multiple software applications also implements storage virtualization. It is mainly used for recovery purposes and keeping a backup of critical data and information.
Thus, the different types of hypervisors in cloud computing play a very important role in managing, operating and installing cloud systems in the operations of a business.

Types of Clouds in Cloud Computing
Cloud computing has various kinds of architecture. The different types of cloud computing are a part of the framework or architecture of the cloud. The types of cloud in cloud computing are enumerated as follows:
Public Cloud
A public cloud is a type of cloud where the services and data are available to the public in general. It is not dedicated to a specific user or company. Customers do not control the location of the architecture or information. This type of cloud is cost-effective as the expenses are shared by all the users of the public cloud. It is great for companies that need to manage the host applications and other applications that are mostly utilized by users.
Private Cloud
A private cloud is solely dedicated to a particular organization or a user. The data in this type of cloud is much more secure and remains in control of the organization. The host can either be external or internal. Companies that are subjected to high-security demands should resort to private clouds and keep up with the requirements.
Hybrid Cloud
A hybrid cloud is a combination of private and public clouds and it possesses the qualities of both. A hybrid cloud will allow a user to launch a safe host app with the features of a public cloud. Where there is more security required, it will automatically switch to the private cloud. Users can easily switch between the features of two clouds. A hybrid cloud is one of the most cost-effective clouds.
Community Cloud
When a group of companies and startups can access a cloud together, it is termed a community cloud. The infrastructure of the cloud is shared amongst the companies that have the same areas of interest and concerns. Community clouds are generally regulated by third parties. This cloud provides adequate security and is cost-effective.
Thus, these are the types of cloud in cloud computing that are necessary for the storage and sharing of data within an organization or with other organizations and users.
Types of Cloud Computing Services
Cloud computing services have a positive impact on businesses and the way they deal with information technology. The major types of cloud computing services are as follows:
Software as a Service (SaaS)
Storage as a Service or SaaS is a service that is offered by the cloud platform for storage. It helps you to rent data storage that is either determined by quantity or is based on the service level provider that states certain parameters such as the uptime and access speed. It gives you the additional feature of data security.
Infrastructure as a Service (IaaS)
Infrastructure as a service or IaaS is a type of cloud computing service that provides virtual computing resources through the internet to the intended users. It is one of the main components of cloud computing and protects users from incurring huge costs and complexities.
Platform as a Service (PaaS)
PaaS also known as Platform as a Service is for those who are searching for top-notch quality but at a low budget. This app already has a prepared code of the software which can be used to create new applications as coding and updating software is time consuming.
Thus, cloud computing services help businesses to get an idea about what they should provide to their clients keeping in mind the costs as well.

Types of Scaling in Cloud Computing
The increase or decrease in the resources of IT to meet the ever-changing demand is known as cloud scalability. The power of data storage, processing, and networking can be increased with the help of cloud scalability. The various types of scaling in cloud computing are enumerated as follows:
Vertical Scalability
The addition and subtraction of resources and data, memory, and storage within a particular server is possible with the help of vertical scalability in the cloud. However, the resources should not exceed the machine’s capacity. It helps to avoid overmanagement and latency and improves your cloud server.
Horizontal Scalability
Horizontal scalability refers to the addition of more networks to your server. This method is however a complex one and involves more time. Horizontal scalability helps to build more efficient servers that allow connectivity and traffic management and adjust to the ongoing workloads.
Diagonal Scalability
Diagonal scalability is a combination of both vertical and horizontal scaling. Here, the addition of resources takes place both horizontally and vertically. It is considered to be the most efficient infrastructure scaling. It helps you to grow within the existing server till the maximum capacity is reached. Also, server cloning takes place to effectively continue the process and control traffic.
Thus, the different types of scaling in cloud computing help you to build effective resources throughout the existing or new servers of the organization.
Conclusion
With the advent of cloud computing, organizations have changed their way of dealing with data and information. It has become easier for companies to transfer and share data, keeping in mind the security of the same. Technological advancement has resulted in more usage of cloud infrastructure and services.
