Software as a Service (SaaS) companies have revolutionized the way businesses operate, providing a wide array of advantages such as cost-effectiveness, scalability, and a focus on core competencies. This article offers an in-depth look into the technology behind SaaS, the benefits it provides to businesses, and some ongoing challenges these companies face. Examples of prominent SaaS solutions such as Salesforce and Dropbox will be used to highlight these points.

The Technology Behind SaaS

SaaS is a software distribution model in which applications are hosted by a service provider and made available to customers over the internet. Traditional software applications required the customer to purchase licenses and install the software on individual computers, while in a SaaS model, customers access the software via a web browser, often on a subscription basis.

Technically, the magic behind SaaS lies in cloud computing. The SaaS provider hosts both the software and the underlying database in the cloud. This setup allows incredibly efficient modifications or improvements, with alacrity of deployment across all customers. With access to the software made possible through the Internet, updates are seamless and automatic.

Salesforce, for example, is a perfect representation of a SaaS provider. Their Customer Relationship Management (CRM) software is accessed via a web browser, and all customer data is stored on Salesforce’s servers, not the end user’s computer.

Advantages of SaaS

The range of advantages SaaS offers are plenty. Its pay-as-you-go subscription model can reduce cost significantly since businesses do not have to invest heavily upfront on licenses and hardware.

Scalability and accessibility are other fundamental advantages. Since the software is hosted in the cloud, businesses can easily scale up or down, based on their usage. Workers can access SaaS applications from any Internet-enabled device or location, promoting remote collaboration.

Moreover, SaaS allows businesses to focus on their core competencies while the SaaS vendor takes care of the software application. This aspect proves advantageous for businesses that do not possess the necessary IT skills.

Dropbox is a great example to showcase the advantages of a SaaS model. It allows users to store and share massive files digitally, eliminating hefty costs for physical storage and promoting collaboration across different locations.

Challenges Faced by SaaS Companies

While SaaS provides numerous benefits to businesses, the model still faces several hurdles.

Firstly, SaaS applications depend entirely on an Internet connection. Hence, any downtime or connectivity issues mean potential business operation disruptions.

Secondly, while data leakage and security concerns can happen with any technological model, they are particularly ominous for SaaS applications since the provider hosts everything on the cloud.

Lastly, integrating the SaaS application with existing on-premise systems poses a significant challenge, especially in cases where the existing systems are outdated.

From a company’s standpoint, Evernote’s example is worth noting. They faced significant churn due to issues related to stunted product development and reliability concerns, highlighting that even successful SaaS companies face obstacles in pursuing continuous growth.


The SaaS model, backed by cloud computing, is a game-changer. While enabling cost reductions, scalability, and focus on core competencies, it is crucial to acknowledge the hurdles that come along. As with any technology, it is about leveraging the best it has to offer while minimizing potential risks. There is no doubt that SaaS has and will continue to significantly influence the software landscape, making it an exciting space to watch.”
