Different Types of Cloud Computing Service Models

Throughout history, humans have always needed better ways to store and access information. In the past, essential data was saved on paper, whereas today it is primarily stored on hard drives and servers. Although these storage devices have been handy, they have limitations. As companies and industries grow, the need for larger and more efficient data storage solutions has become a necessity. This is where Cloud Computing comes in handy!

Before the rise of Cloud Computing platforms, businesses used servers, databases, hardware, software, and other peripherals to get online. Companies had to purchase these components for their website or applications to be accessible to people. In addition, organizations require a team of professionals to handle the hardware and software, as well as to monitor the infrastructure. While this strategy was practical, it had its own set of disadvantages, such as high setup costs, complex components, and limited storage space. Cloud computing was developed to overcome these issues. 

What is Cloud Computing? 

Cloud computing is a technology that provides computing services over the Internet, including servers, storage, databases, networking, software, analytics, and intelligence. It allows individuals and businesses to access computing resources without needing to invest in and upkeep their infrastructure. With cloud computing, users can access applications, data, and services from anywhere with an internet connection, providing flexibility and scalability to businesses and enabling them to innovate and grow without the added concern of IT infrastructure.

By using cloud computing, businesses can easily store, analyse, and retrieve large amounts of data promptly. Cloud computing courses can help individuals become experts in cloud applications and architecture, allowing them to stay ahead of the curve in the IT industry.

What Are Cloud Services?

The term "cloud services" refers to a wide range of on-demand services supplied to businesses and users via the Internet. These services are intended to enable simple, low-cost access to applications and resources that do not require internal infrastructure or hardware. Most employees utilise cloud services throughout the workday, whether they are aware of it or not, from checking email to collaborating on documents. Cloud computing manufacturers and service providers fully handle cloud services. Customers access them through the providers' servers, eliminating the need for a corporation to host apps on its on-premises servers.

Cloud services are infrastructure, platforms, or software hosted by third parties and made available to users via the Internet. Cloud services enable the movement of user data from front-end clients (e.g., users' servers, tablets, desktops, laptops, or anything else on the users' end) to the provider's systems and back. Cloud services encourage the development of cloud-native apps as well as the freedom of working in the cloud. Users only need a computer, an operating system, and internet access to use cloud services.

Types of Cloud Computing Services 

There are three main types of cloud computing services that businesses can choose from based on their needs and requirements. These include Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Let’s see these in detail.

  • Software as a Service (SaaS)
  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)

Software as a Service (SaaS)

Software as a service, or SaaS, is the most well-known sort of cloud service. This broad category includes a wide range of services, including file storage and backup, web-based email, and project management tools. Dropbox, G Suite, Microsoft Office 365, Slack, and Citrix Content Collaboration are examples of SaaS cloud service providers. Users can access, share, store, and safeguard information in "the cloud" through each of these applications.

Platform as a Service (PaaS)

Platform as a service, or PaaS, is a cloud service model that provides a web-based environment for developers to construct cloud apps. PaaS offers a database, operating system, and programming language that businesses may use to create cloud-based software without having to manage the underlying components. Many IaaS companies, including the ones mentioned above, also provide PaaS services. 

Infrastructure as a Service (IaaS)

IaaS, or infrastructure as a service, provides the infrastructure that many cloud service providers require to operate SaaS products but do not wish to maintain. It acts as the entire data centre foundation, removing the requirement for resource-intensive on-site deployments. Amazon Web Services (AWS), Microsoft Azure, and Google Compute Engine are examples of IaaS. These companies maintain all storage servers and networking gear, and they may also provide load balancing, application firewalls, and other services. IaaS systems are used by several well-known SaaS firms.

Types of Cloud Deployment Models

Cloud deployment models are ways of categorizing how cloud services are delivered. When deciding how to use cloud services, businesses must also consider which type of environment is ideal for them: public cloud, private cloud, or a hybrid of the two. There are four cloud deployment models, such as: 

  • Private cloud
  • Community cloud
  • Public cloud
  • Hybrid cloud

Now, let us take a brief look into each cloud deployment model;

Private Cloud

A Private cloud, is a cloud deployment model that provides dedicated cloud resources to a single organization. It is usually hosted on-site, and the organization has complete control over the cloud infrastructure. Private clouds are beneficial for organizations looking for high levels of security and privacy.

Community Cloud

Community cloud is a cloud deployment model that provides shared cloud resources to a specific group of organizations. It is usually hosted either on-site or off-site and is managed either by organisations in the community or by a third-party provider. It provides a level of security and privacy that is higher than the public cloud but lower than the private cloud.

Public Cloud

Public cloud is a cloud deployment model that provides cloud resources to the public over the Internet. It is hosted by a third-party cloud service provider and is usually the most cost-effective option for organizations looking for cloud-based services. It offers scalability and flexibility but may lack the security and privacy of the other cloud deployment models.

Hybrid Cloud

Hybrid cloud is a cloud deployment model that combines public cloud services with private cloud resources. It provides the scalability and flexibility of the public cloud, while also offering the higher levels of security and privacy of the private cloud. Hybrid cloud allows organizations to take advantage of the benefits of both the public and private clouds, while also allowing for the portability of data and applications between the two.

Public Cloud Services vs. Private Cloud Services

Public cloud services are those that a provider makes available to many consumers via the Internet. The examples of SaaS, IaaS, and PaaS mentioned above all provide public cloud-based services. The capacity to share resources at scale is the most significant advantage of employing public cloud services, allowing firms to give employees greater capabilities than would otherwise be available.

Whereas, Private cloud services are those that a provider does not make widely available to corporate users or subscribers. Apps and data are made available through the organization's own internal infrastructure under a private cloud services model. The platform and software are only used by one company and are not accessible to outside users. Private clouds are frequently used by companies that operate with extremely sensitive data, such as those in the healthcare and finance industries, to use enhanced security mechanisms and extend resources in a virtualized environment as needed.

A private cloud solution is integrated with public cloud services in a hybrid cloud environment. This arrangement is frequently used when a company requires sensitive data to be stored in the private cloud but wants employees to have access to apps and resources in the public cloud for day-to-day communication and collaboration. To enable communication across cloud services, proprietary software is often utilised, often through a single IT administration portal.
