Cloud computing has changed the way we use and interact with technology. It allows users to access computing resources over the internet. There is no need for on-premises hardware or maintenance. The increasing demand for digital services is making cloud computing essential for businesses and individuals alike. Let’s explore the five different types of cloud computing:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
- Function as a Service (FaaS)
- Desktop as a Service (DaaS)
Every single one of these types of cloud computing offers different levels of abstraction and management of the underlying infrastructure. IaaS provides the basic infrastructure components needed to run an application or service. PaaS offers a platform for customers to develop, run, and manage applications. SaaS delivers software applications over the internet. FaaS allows developers to write and deploy code without managing the underlying infrastructure. DaaS enables users to access a virtual desktop environment from anywhere.
Let’s have a look into these types of cloud computing using simple terms. We will also provide examples of how and when they are put to use. By the end of this article, you will have a better understanding of the different types of cloud computing.
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is the first of the five types of cloud computing. It allows users to access computing resources like virtual machines, storage, and networking over the internet. Customers are responsible for configuring and managing their own virtual machines. Cloud computing providers manage the underlying infrastructure.
Some everyday examples of infrastructure as a service are Amazon Web Services, Microsoft Azure, and Google Cloud Platform. Some benefits of using IaaS are cost savings, scalability, and flexibility. They even enable users to avoid upfront costs and maintenance of on-premises hardware.
IaaS is suitable for scalable web applications that need to adjust to changing demand, as it can quickly provide additional resources as needed. It is particularly useful for disaster recovery, as it provides a cloud-based backup solution that is accessible from anywhere.
Another advantage of IaaS is its ability to provide a consistent infrastructure across multiple environments, such as development, testing, and production. This ensures that applications run consistently, regardless of the underlying infrastructure.
However, IaaS can also present some challenges, including the need for technical expertise to configure and manage virtual machines, and the risk of vendor lock-in if applications are tightly coupled to the IaaS provider’s infrastructure.
In summary, IaaS provides users with on-demand access to computing resources, reducing the need for upfront hardware investments and enabling scalability and flexibility. Its use cases include scalable web applications and disaster recovery, as well as providing a consistent infrastructure for multiple environments.

Platform as a Service (PaaS)
Another sort of cloud computing is platform as a service (PaaS), which provides a platform for developers to build, launch, and manage applications. Developers can concentrate on building code while the supplier controls the underlying infrastructure with PaaS.
Heroku, Google App Engine, and Microsoft Azure are examples of PaaS providers. Benefits of using PaaS include faster time-to-market, increased productivity, and reduced costs, as developers can focus on writing code instead of managing infrastructure.
PaaS is ideal for application development and deployment because it provides a scalable and adaptable environment for testing, staging, and production. Developers can easily collaborate and share code with others, while the provider manages the underlying infrastructure, including operating systems, middleware, and runtime environments.
PaaS has the capability to integrate with various other cloud services like databases, message queues, and caching services. This integration provides developers with an uninterrupted end-to-end development experience.
However, PaaS can also present some challenges, including limited control over the underlying infrastructure and potential vendor lock-in. Developers must also ensure that their applications are compatible with the PaaS provider’s environment. Not all applications are compatible with all platforms.
PaaS provides a platform for developers to build and deploy applications. This allows them to focus on creating code rather than maintaining infrastructure. Its application development and deployment use cases include offering a scalable and adaptable environment for testing, staging, and production.
Software as a Service (SaaS)
Software as a Service (SaaS) is a type of cloud computing that allows users to access software applications over the internet. The user does not have to install or maintain the software themselves. The SaaS provider hosts the software and makes it available to users through a web browser or mobile app.
Some examples of SaaS providers you know are Google Workspace, Salesforce, and Microsoft Office 365. The benefits of using SaaS include reduced costs, increased accessibility, and easier collaboration. Users can even access the software from anywhere with an internet connection.
SaaS is well-suited for a variety of use cases, including email, customer relationship management (CRM), and productivity tools. SaaS providers offer a wide range of software applications for businesses and individuals, from accounting software to project management tools.
One of the advantages of SaaS is its ability to scale up or down quickly. This allows businesses to adjust their software needs as they grow or change. SaaS providers also handle software updates and maintenance. This reduces the burden on businesses and individuals.
SaaS can also have some challenges. Some of these are concerns about data security and privacy. Another is the potential integration issues with other software systems.
SaaS allows users to access software applications over the internet. This is without having to install or maintain the software themselves. Its use cases include email, CRM, and productivity tools, and its benefits include reduced costs and increased accessibility.
Function as a Service (FaaS)
Function as a Service enables developers to write and run code without worrying about the underlying infrastructure. FaaS providers handle the infrastructure and scale resources automatically based on usage.
Some examples of FaaS providers you know are AWS Lambda, Azure Functions, and Google Cloud Functions. The benefits of using FaaS are reduced costs, increased scalability, and faster development cycles.
FaaS is well-suited for event-driven computing and microservices architecture. In event-driven computing, FaaS can be used to trigger code based on specific events, such as user actions or system events. FaaS can be used to break down applications into smaller, more manageable components for microservices architecture.
One of the advantages of FaaS is its ability to handle short-lived and stateless functions. This reduces the complexity of the code and allows for faster development cycles. FaaS providers also handle scaling and resource management, freeing up developers to focus on writing code.
FaaS does have some issues. These are potential vendor lock-in and increased complexity in managing multiple functions and workflows.
FaaS allows developers to write and run code without worrying about the underlying infrastructure. Its use cases include event-driven computing and microservices architecture. Its benefits include reduced costs and faster development cycles.

Desktop as a Service (DaaS)
Desktop as a Service (DaaS) is the fifth and final type of cloud computing we’ll be exploring. DaaS is a virtual desktop infrastructure (VDI) delivered as a service over the Internet. DaaS is the same as having a fully functional desktop computer in the cloud that you can access from any location and with any device.
Examples of DaaS providers include Amazon WorkSpaces, Citrix Virtual Apps and Desktops, and Microsoft Azure Virtual Desktop. Benefits of using DaaS include increased mobility and flexibility, as well as reduced hardware and maintenance costs. DaaS is particularly useful for remote work scenarios, where employees need access to company data and applications from various locations and devices.
Other use cases for DaaS include data security and compliance, as it allows for centralized management and control over sensitive data. DaaS can also be used for disaster recovery because it provides a dependable and accessible backup of critical data and apps.
