What is SaaS?

SaaS, which stands for Software as a Service, is a software licensing and delivery model that has gained widespread popularity in recent years. Under the SaaS model, a software application is hosted centrally in the cloud by a vendor and made available to customers over the internet, typically on a subscription basis. Well-known examples of SaaS include customer relationship management platform Salesforce, productivity suite Google Workspace, file storage service Dropbox, and video conferencing tool Zoom.

Instead of installing and maintaining software on their own computers or in on-premises data centers, companies simply access the application via a web browser. The SaaS provider manages the software, handling maintenance, updates, security, and data storage in the cloud. This allows businesses to offload complex software management and quickly scale their usage up or down as needed.

The rise of SaaS has been driven by the widespread adoption of cloud computing, which enables the efficient and secure delivery of software over the internet. According to a report by Gartner, the global SaaS market is expected to reach $140.6 billion by 2022, up from $102.1 billion in 2019. This rapid growth reflects the increasing recognition of the benefits SaaS offers over traditional on-premises software deployment.

From a technical perspective, SaaS applications are typically built using a multi-tenant architecture, where a single instance of the software serves multiple customers. This allows the SaaS provider to achieve economies of scale and efficiently manage updates and patches across their customer base. SaaS applications are usually accessed through a web browser, with data stored in the cloud and processed on the provider's servers.

Many SaaS applications leverage advanced technologies like artificial intelligence, machine learning, and big data analytics to deliver intelligent features and automate tasks. For example, Salesforce's Einstein AI platform powers predictive analytics and intelligent recommendations within the company's CRM suite.

Advantages of the SaaS model

One of the key benefits of SaaS is the potential for significant cost savings compared to traditional on-premises software. With SaaS, companies can avoid large upfront hardware and software licensing costs. The subscription model turns software into an operating expense rather than a major capital investment. Automatic updates and patch management by the provider also reduce IT maintenance costs.

For example, consider a small marketing agency that needs a robust project management tool. Instead of purchasing expensive server hardware and perpetual software licenses, they can subscribe to a SaaS solution like Asana or Trello for a low monthly fee per user. This allows them to access enterprise-grade functionality without the hefty upfront investment.

SaaS offers unmatched flexibility and scalability for growing businesses. New users can be added easily without the need to purchase additional software licenses or server capacity. Employees can access the software from anywhere with an internet connection using a variety of devices, enabling remote work and productivity on the go. SaaS vendors also handle software updates and upgrades seamlessly, ensuring customers always have access to the latest features and security patches.

A real-world example of SaaS scalability in action is the rapid growth of video conferencing platform Zoom during the COVID-19 pandemic. As businesses shifted to remote work, Zoom's user base skyrocketed from 10 million daily meeting participants in December 2019 to over 300 million by April 2020. The SaaS model allowed Zoom to quickly scale its infrastructure to meet this unprecedented demand without customers needing to worry about capacity constraints. Zoom's architecture, built on AWS, allowed the company to rapidly add server capacity and leverage advanced features like auto-scaling to handle the surge in usage.

SaaS applications are also typically designed with user-friendliness and ease of adoption in mind. Many SaaS vendors offer free trials, allowing businesses to test drive the software before committing. The web-based interfaces are intuitive and require minimal training, enabling faster employee onboarding. Some SaaS platforms, like the low-code development tool Airtable, even allow non-technical users to create custom applications without writing code.

Low-code and no-code SaaS platforms democratize software development by enabling business users to build applications using visual, drag-and-drop interfaces. This can greatly accelerate digital transformation initiatives and reduce the burden on IT teams. For instance, a human resources department could use a low-code SaaS platform like Appian to quickly build a custom employee onboarding application, complete with automated workflows and integration with existing HR systems.

Potential drawbacks to consider

While SaaS provides compelling advantages, organizations should carefully evaluate a few tradeoffs. Because the software is hosted externally by the vendor, businesses may have less control over the application and their data. Customization options may be more limited compared to on-premises deployments. Companies must also rely on the vendor to maintain a highly available, secure, and high-performance environment.

For industries with stringent regulatory requirements, such as healthcare and finance, the use of SaaS may be more complex. Compliance with regulations like HIPAA, PCI-DSS, and GDPR can be challenging when data is stored off-premises. However, many SaaS providers specifically cater to these industries and offer compliant solutions. For example, Veeva Systems provides a suite of SaaS applications designed to meet the strict data privacy and security requirements of the life sciences industry.

Storing sensitive business data in the cloud raises valid security concerns. However, leading SaaS providers typically employ robust security measures and may have more resources to devote to security than the average business. Customers should carefully review the vendor's security practices, certifications, and contractual liability for data breaches.

Reputable SaaS providers invest heavily in security and undergo regular third-party audits to validate their controls. Look for vendors that are transparent about their security measures and have achieved certifications like SOC 2, ISO 27001, or FedRAMP. Many leading SaaS companies, such as Salesforce and Box, also offer granular access controls, data encryption, and advanced threat detection to help customers protect their data.

From a technical standpoint, SaaS providers employ a variety of security measures to protect customer data. These include:

SaaS: a cost-effective alternative

For many businesses, the benefits of SaaS far outweigh the potential drawbacks. The subscription-based model can dramatically reduce both upfront and ongoing software costs. For example, a mid-sized retailer migrated from an on-premises customer database to a SaaS CRM platform, cutting their software TCO by 50% over 3 years when considering hardware, maintenance, and upgrade costs no longer needed.

Another illustrative case study is the experience of the City of Orlando. By switching from on-premises email servers to Google Workspace, the city government was able to save $140,000 annually in IT costs while providing employees with more modern collaboration tools. The SaaS model allowed them to reduce infrastructure expenses, eliminate upgrade cycles, and enable secure remote work for city employees.

SaaS allows companies to preserve capital for other business investments and provides much clearer visibility into ongoing software costs to inform budgeting. With the vendor handling software maintenance and updates, businesses can focus their IT resources on higher-value tasks and strategic initiatives rather than routine software management.

The scalability of SaaS also means businesses only pay for the resources they actually use. This is particularly advantageous for applications with fluctuating usage patterns. For instance, an e-commerce company can leverage a SaaS platform like Shopify to easily handle spikes in traffic during peak shopping seasons without overprovisioning infrastructure year-round.

From a technical perspective, the multi-tenant architecture of SaaS enables providers to achieve significant economies of scale. By running a single instance of the software that serves multiple customers, SaaS providers can spread the costs of infrastructure, maintenance, and updates across their entire customer base. This allows them to offer more competitive pricing compared to traditional on-premises software.

SaaS providers also leverage advanced technologies like containerization and serverless computing to further optimize their infrastructure and reduce costs. For example, using Kubernetes to orchestrate containers allows SaaS providers to efficiently pack workloads onto servers and automate scaling and failover. Serverless computing platforms like AWS Lambda enable SaaS providers to run code without provisioning or managing servers, paying only for the compute time actually consumed.
