What is Software as a Service (SaaS) - Definition, Advantages, & Examples

Software installation and maintenance process can be hectic and time-consuming. However, the software can solve this problem as a service solution that delivers the application over the Internet. As we know, there are cloud-based services available that offer global accessibility and scalability to customers. So, in this article, we will discuss the SaaS with its benefits, challenges, and other details to clarify our understanding.

Part 1: What is Software as a Service (SaaS)?

Software as a Service is cloud-based software where the cloud provider hosts applications and makes them available to the end user. These cloud-based tools provide a way to access the software rather than installing and maintaining it. This delivery model maintains the hardware and software and updates them automatically. The user needs to make an account, pay a fee, and get the required services for optimal usage.

Additionally, it saves the user time as it is a ready-made solution, and the provider gives access to the application with security. The application of SaaS can run on any mobile device and web browser, making it more flexible for all customers. This delivery model offers a service to businesses and organizations with low to no management problems.

Part 2: What are the Advantages of SaaS?

After getting the idea of what is SaaS, its advantages should be considered to improve understanding of this service application. There is no need for software licensing as it provides a streamlined approach to adopting and using the software. Also, some other benefits offered by the software as a service software have been discussed below:

  • Access to New Features and Versions: SaaS provides the benefit of upgrading features and adding new functionality without the need for user interference. This upgrade process happens without notice and disturbs the user's work. It is helpful for the user as traditional software needs costly and disruptive upgrades. Moreover, the addition of new functionality in software takes time of months.
  • Cost-effective and On-Demand Scalability: Unlike traditional software, SaaS provides on-demand scalability. The application of the SaaS can be scaled up and down as per requirement. The traditional software user needs to purchase the capacity in anticipation that it might get wasted. This advantage saves money and makes software as a service cost-effective.
  • Easy Customization: SaaS can easily customize the application to fit any business process. The unique customization demand of any user can be fulfilled through it without affecting the shared infrastructure. Additionally, compared to traditional software that does not offer customization, SaaS offers flexibility to its users.
  • Faster Adoption: Users can start using the software as a service immediately after installing it due to its faster adaptability. The first subscription cost of SaaS is less and in the predictable budget of the user. On the other hand, traditional software takes time in the purchasing and installation process, making them less adaptable. This advantage makes this service more popular among the users.

Part 3: What are the Disadvantages of SaaS?

The SaaS defined above has the advantage of being a user-friendly cloud-based software. It provides an update service without noticing users and can increase the organization. Nevertheless, there are some potential risks and challenges that users need to know. The business relies on this service, so the disadvantages are discussed below for the awareness of the user:

  • Loss of Control: The users can't control the issues they encounter while using the SaaS. These issues might be service disruptions, security breaches, and unwanted changes. Sometimes, the cloud provider completely shuts down and goes out of control without warning. In addition, the data is at risk in this loss of control situation because the user cannot mitigate the risk.
  • Switching Vendor Problem: The difficulty comes in switching vendors when using any cloud service provider. A considerable amount of data must be migrated to switch to cloud-based software, making it disruptive for SaaS users. Moreover, this data transfer becomes more difficult due to different data types and proprietary technologies.
  • Security: There is insufficient data security in this cloud-based software service. A company's sensitive data gets stored in a service provider's data center that cybercriminals can access easily. It is a third-party service, and users have concerns regarding sharing vital information. The sensitive data can be accessed quickly and used for the wrong purposes.
  • Low Performance: This web-based application might perform poorly compared to a similar application running on the desktop. This application runs on a remote data center and needs a stable internet connection. Also, this low performance can affect the efficiency of the work as it takes time.

Part 6: Is SaaS Safe?

SaaS is easy-to-use cloud-based software that offers scalability. However, it has some security concerns as users' critical data is stored in it. There is a risk of exposure to this sensitive data by unauthorized access. Other than that, it relies on the internet's connectivity, so any disruption can delay the accessibility to the required application.

There is a need to develop a multilayer security system for avoiding unauthorized access to sensitive data. Regular audits of security and unauthorized access can also improve it. These practices can reduce the inherent security risk of the software as a service software and ensure safety in this computing model. Users can then rely on this cloud-based service without having any safety concerns. UPDF has all these features to ensure safe and secure cloud-based PDF management.
