SaaS in cloud computing

Software as a Service, or SaaS, enables users to access and utilize cloud applications online.

SaaS in cloud computing is fast replacing on-premises software because it’s more convenient and can integrate easily into business SOPs and workflows without noticeable disruption.

In addition, SaaS is much less expensive because the end users don’t have to pay for software hosting and maintenance. Instead, they only pay subscription fees (monthly or yearly) to access and use the service.

Popular examples of SaaS applications cover a wide range of use cases, including office productivity tools (Google Workspace, Microsoft 365), customer relationship management (Salesforce), file storage and sharing (Dropbox), project management (Trello), and video conferencing (Zoom).

Since SaaS is a popular way to use software on the Internet, we’ll explore how it works, its benefits, and how it differs from traditional software delivery processes.

Let’s start with some definitions.

What Does ‘as a Service’ Mean in Saas in Cloud Computing?

Until just a couple of years ago, software developers used to sell standalone copies of their products to users. New versions and patches had to be manually distributed to the users.

Now, the SaaS model allows them to efficiently manage the distribution and maintenance of software for their customers. The developers handle the product’s frontend and backend data processes and deliver the software as a “service” rather than a standalone product.

SaaS in cloud computing

As a cloud computing model, SaaS has revolutionized how software is delivered, accessed, and used. It represents a fundamental shift from traditional software distribution methods, where users would purchase and install software on their local computers and company servers.

In the SaaS model, software is hosted and provided over the Internet, accessible through web browsers, and typically offered on a subscription basis.

How Does SaaS Work?

Simply put, instead of installing software on your computer, you access SaaS through a web browser.

SaaS applications are hosted on remote servers by the software vendors, which takes care of maintenance, updates, and security. Users pay a subscription fee to use the software, typically monthly or yearly.

This cloud-based model offers advantages like accessibility from anywhere, smooth scalability, automatic updates, and reduced maintenance overhead. For the users, SaaS is an efficient and cost-effective way to access and use software without worrying about hardware and software compatibility issues.

Plus, users can use the APIs provided by SaaS apps to integrate the functionalities in other custom-built applications. These integration options greatly enhance user loyalty, and software developers can generate significant revenues from deploying SaaS in cloud computing environments.

Characteristics of SaaS Products

SaaS cloud solutions are built for all users, regardless of their knowledge and technical skills. In fact, many developers aim to make their products so easy to use that lay users in the target industry could utilize the functionality to achieve their business objectives with just minutes of training.

Characteristics of SaaS in cloud computing

A quick look at all popular SaaS products will help you identify some common characteristics that are instrumental in the success of any SaaS product. Cloud-based software services offer the following critical features:

Always Available

As a general rule, a SaaS product is always up and running.

This always-availability results from the underlying service delivery infrastructure that the hosting provider manages. In addition, the developers also keep a close eye on the operations so that they can jump in and fix any issues that might arise and prevent users from using the product.

This high availability is one of the critical benefits of dedicated servers and the cloud computing industry that has contributed to the rise of SaaS in cloud computing as the predominant industry model.


SaaS applications can be accessed from anywhere with an Internet connection, allowing users to use these software tools remotely, fostering collaboration and operational flexibility. Accessibility is a critical benefit of virtualization in cloud computing that ensures developers can use various virtualization technologies to deliver services without interruptions.

Automatic Updates

SaaS providers handle software updates, ensuring users can access the latest features, bug fixes, and security patches without manual local installation.


SaaS applications are designed to be scalable, allowing users to easily adjust the number of licenses or resources they need as their requirements change. This scalability makes SaaS suitable for both small businesses and large enterprises.

Subscription Model

Almost all SaaS products operate on a subscription basis, typically with monthly or yearly payment options. This pricing model provides a predictable cost structure and often eliminates the need for large upfront investments in critical software products.


SaaS applications support multi-tenancy, meaning multiple customers or organizations can use the same software instance. The data and configuration for each user are isolated from the rest of the users and the primary application data.

Data Security

SaaS products generally collect a lot of information as they deliver services to users. While most of the information is not sensitive, users often give out critical information that could explicitly identify them or cause a financial loss in case of misuse.

SaaS products have a multi-layer structure with data security at every layer. Developers further protect user data by integrating authentication protocols and encryption algorithms in their SaaS products. In addition, developers often find ways to avoid collecting sensitive user information to prevent legal problems and comply with user-rights protection regulations.

Integration Support

SaaS applications often offer Application Programming Interfaces(APIs) that developers can use to enable integration with other software systems. This simplifies data exchange that can power diverse workflows.

User Support

SaaS providers typically offer customer support to help users with any issues or questions. In most cases, SaaS products have a comprehensive knowledge base and tutorials that users can refer to resolve queries on their own.

Collaboration Tools

SaaS applications include built-in collaboration features such as document sharing, real-time editing, and communication options to enhance teamwork and help users collaborate on multiple tasks.

Cross-Platform Compatibility

Developers build SaaS applications to be platform-agnostic. This design choice means users can access and use these products on most devices and operating systems. This compatibility promotes accessibility and integration with popular tools.

These features collectively contribute to the popularity of SaaS as a convenient, cost-effective, and flexible way to deliver, access, and use software. Users don’t have to worry about buying the right hardware or installing software on their local machines – a win-win situation for everyone!

Disadvantages of SaaS

Like all external resources, SaaS products can introduce business risk where external vendors maintain SaaS products. In addition, SaaS products can have the following drawbacks:

Dependency on the Internet

SaaS applications require a reliable and fast internet connection. Users may experience disruptions in accessing and using the software if the internet connection is slow or unavailable.

Data Security Concerns

Storing data off-site on cloud platforms can raise security and privacy concerns. Businesses must trust their SaaS providers to implement robust security measures to protect sensitive data.

Limited Customization

Some SaaS applications may have limited customization options. This can be a drawback for businesses with unique or project-specific requirements that the standard SaaS configuration cannot meet.

The Downtime Challenge

SaaS services are hosted on remote servers, and occasional service outages or downtime can disrupt business operations if the developers don’t have redundant service delivery infrastructure. While SaaS hosting providers strive for 100% uptime, occasional issues can occur.

Compliance Requirements

Using SaaS can complicate meeting specific industry or regulatory compliance requirements. In most cases, businesses should understand that SaaS products may store their data in various locations and under different legal jurisdictions. Ensuring compliance with each jurisdiction can be a significant undertaking.

In addition, SaaS solutions tailored for private clouds necessitate vendor-provided configuration and training.

Bare Metal Servers for SaaS

All hosted SaaS products face unpredictability.

The volume of users and requests from individual users fluctuates over time. While developers can predict this workload as data accumulates over months and years, they still need reliable infrastructure for service delivery. Many SaaS products in cloud computing opt for bare metal servers because these hosting solutions offer the best mix of resource availability and flexible allocation.
