What Are the Best Applications of SaaS in Cloud Computing

SaaS in Cloud Computing

SaaS, which stands for Software as a Service, enables users to access and utilize cloud-based applications via the Internet. Some of the most commonly known examples of SaaS are email, calendaring, and office tools like Microsoft Office 365. SaaS in cloud computing offers a comprehensive software solution that you can buy from a cloud service provider on a pay-as-you-go basis.

SaaS in cloud computing is fast replacing on-premises software because it’s more convenient and can be easily integrated into current SOPs and workflows without noticeable disruption. In addition, SaaS is much less expensive because the end users don’t have to pay for hosting and maintenance of software. Instead, they only pay subscription fees (monthly or yearly) to access and use the service.

Since SaaS is one of the preferred delivery models in cloud computing, we’ll take a detailed look into how SaaS operates and how it compares to other delivery models in cloud computing so that you can make an informed decision about using SaaS in your cloud computing-related 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. Now, the SaaS model allows them to easily manage distribution and maintenance of software for their customers. They handle front-end and back-end data of the product and deliver the software as a “service” rather than a standalone product.

This structure is often the first thing you’ll see when you start digging into the cloud computing advantages and disadvantages.

How Does SaaS Work?

In a typical SaaS implementation, a hosting provider offers the infrastructure for hosting and distributing the software. This is a great example of virtualization in cloud computing where users (including the software developers) often don’t work with physical resources.

In exchange for a monthly subscription, end users can access the service from any web-enabled device using just a web browser. Plus, users can use the APIs provided by SaaS apps to integrate the functionalities in other custom-built applications.

Examples of SaaS in cloud computing include:

  • Digital Marketing Tools & Platforms
  • Enterprise Resource Planning
  • Customer Resource Management

Characteristics of SaaS Products

SaaS products are built for use by all users, regardless of their knowledge. In fact, many developers aim to make their products so easy-to-use that lay users in the industry could use the functionality to achieve their business objectives.

A quick look at all popular SaaS products will help you identify some common characteristics that are instrumental in the success of a SaaS product.

Always Available

As a general rule, a SaaS product is always up and running. This is made possible by the underlying service delivery infrastructure that is often managed by a high-end hosting provider. 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 important trends in dedicated servers and cloud computing industry that has contributed to the rise of SaaS in cloud computing as the predominant industry model.

Data Security

SaaS products generally collect a lot of information during the course of delivering services to the 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.

That is why security (particularly data security) is built into SaaS products at multiple levels. You’ll find several authentication protocols and encryption algorithms in SaaS products. In addition, developers often find ways to avoid getting sensitive user information to avoid any problems and comply with user-rights protection regulations. All these make SaaS in cloud computing a very secure model for users.


All hosted SaaS products face unpredictability. The volume of users and requests from individual users fluctuate over time. While developers can start predicting this workload as data accumulates over months and years, managing this workload and balancing resource allocation is an ongoing challenge. Many SaaS examples in cloud computing opt for bare-metal servers because these solutions offer the best mix of resource availability and flexible allocation.

Advantages of SaaS in Cloud Computing

When you compare SaaS and other traditional software delivery models (such as on-premises installations), you’ll find that SaaS offers virtualization in cloud computing as one of the most distinctive advantages. In addition, some other advantages that SaaS products brings to the game are:

  1. Businesses pay a small subscription fee and get all the benefits of investing in a costly in-house software support infrastructure.
  2. SaaS can help businesses achieve vertical scalability in using cloud computing services because SaaS products deliver connected features at nominal increase in usage fees.
  3. Automated software upgrades delivered by SaaS products ease operation burden and costs for in-house IT teams.
  4. SaaS applications are very adaptable and integrate seamlessly with other products and custom solutions used by the end users.

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:

  1. Problems can emerge due to frequent service interruptions or security breaches that are beyond the control of end users.
  2. Authentication and verification of users can add delays, particularly in the case of SaaS products that deal with sensitive data and must comply with multiple regulations.
  3. While SaaS providers ask end users for feature recommendations and make their development roadmaps public, chances are that some end users might not need the features released by the developers.

Bare Metal Servers for SaaS

Bare-metal servers give users privacy, transparency, and excellent control because of isolated, client-only “computing instances.” The servers can handle heavy workloads that are typical of popular SaaS products that deliver services to thousands of users.

We make it extremely easy to host SaaS apps and make them available to users all over the world, thanks to high performing bare-metal servers that ensure dedicated resources and scalability without breaking the bank.
