Different Types of Cloud Computing services 

Cloud services play a vital role in Cloud Computing by providing on-demand access to various resources and applications over the internet. They enable organisations to leverage scalable and cost-effective solutions without the need for extensive infrastructure. The hierarchy of these different types of cloud services is as follows:

Infrastructure as a Service 

Infrastructure as a Service (IaaS) provides virtualised computing resources over the Internet. With IaaS, businesses can access virtual machines, storage, and networks to build their IT infrastructure. This eliminates the need for upfront hardware investments and enables scalability as per demand.  

Organisations can deploy and manage their applications, databases, and operating systems within the IaaS environment. This service is suitable for businesses that require complete control over their infrastructure and have fluctuating workloads. 

Platform as a Service 

Platform as a Service (PaaS) provides a comprehensive environment for developing and deploying applications. It provides a platform that includes operating systems, programming languages, databases, and other essential Cloud Computing Tools required for application development.

PaaS allows developers to focus on writing code without worrying about infrastructure management. It offers scalability, as resources can be easily scaled up or down based on application requirements. PaaS is ideal for organisations looking to accelerate application development, reduce time to market, and improve collaboration among development teams. 

Software as a Service 

Software as a Service (SaaS) allows you to skip software installation and maintenance while using them over the internet. SaaS providers host and manage the applications, making them accessible to users through web browsers or mobile apps. This eliminates the need for software installation, updates, and infrastructure management, saving businesses time and resources.   

SaaS applications cover a wide range of functions, including customer relationship management, project management, collaboration tools, and more. This service is suitable for businesses seeking cost-effective and hassle-free software solutions. 

Function as a Service 

The Function as a Service (FaaS), also called Serverless computing, allows developers to run their applications in a serverless environment without needing to provision or manage servers. In serverless computing, the cloud provider takes care of server management, auto-scaling, and resource allocation based on the application's demand.   

Developers can focus solely on writing code in the form of functions, which are executed on demand. This model offers cost efficiency, as businesses only pay for the actual execution time of functions. Serverless computing is well-suited for event-driven applications, real-time data processing, and microservices architecture.
