What is Saas? 7 FAQs About Software-as-a-Service

Software-as-a-Service (SaaS)—also known as cloud based software—is now mainstream. Almost half (48%) of respondents in Gartner’s 2021 Emerging Technology Product Leader Survey who are putting funds toward data and analytics
And for good reason. Business applications delivered via a web browser lack painful installations or strict contracts, and are paid for overtime instead of all at once. This usually makes the systems more flexible and affordable enough for any budget.

1. What is SaaS?
SaaS is a method of software delivery that allows data to be accessed from any device with an internet connection and a web browser. In this web-based model, software vendors host and maintain the servers, databases, and the code that makes up an application.The cloud-based model is so common now that more than 60% of software seekers who call Software Advice only want web-based products—less than 2% specifically ask for on-premise software.

The traditional on-premise software delivery model differs from SaaS in two key ways:

1.) SaaS deployments don’t require extensive hardware, which allows buyers to outsource most of the IT responsibilities typically required to troubleshoot and maintain the software in-house.

2.) SaaS systems are typically paid within a subscription model, whereas on-premise software is usually purchased through a perpetual license, paid upfront.

On-premise users can also pay up to 20% per year in maintenance and support fees. The annual or monthly subscription fee for a SaaS system will typically include the software licensing, support, and most other fees.

2. SaaS versus on-premise: How do I choose?
The first step to answering this question is to determine the complexity of your business. Answer a few questions about your business to help you determine if SaaS is the best choice:

* How specialized is your business compared to others in your industry?
* Do off-the-shelf products offer the functionality you need?
* What level of software customization do you anticipate needing?

Another factor to consider is your budget. As mentioned above, SaaS subscription payment models help companies with smaller budgets spread the total cost of ownership over time, so even small businesses can adopt robust, modern software.

It’s no longer the case that buyers have to choose between flexibility and functionality. Most cloud based software today can offer the exact same experience as an on-premise installation.

The bigger question is around data ownership. The vast majority of vendors still place data in the possession of the end user, but be sure to review the service contract to understand exactly how your data will be used.

A few industries are slower to embrace cloud solutions (for example, many manufacturers still opt for a traditional ERP deployment), but when searching for new technology, the cloud is the new default.

3. What is the history of SaaS?
In a 1961 speech to MIT students, John McCarthy, a renowned computer scientist that won the Turing award for his work in artificial intelligence (AI), famously said, “computation may someday be organized as a public utility.” In other words, the concept of cloud computing began as a shared resource of computing power.

While the idea has been around for some time, the web-based technology required to support SaaS matured in the late 1990s. That’s when companies such as Salesforce—which was founded specifically to create cloud software—began offering traditional enterprise solutions, such as customer relationship management (CRM), through a SaaS model.
At first, the enterprise software world didn’t take SaaS seriously. But the past decade has shown rapid SaaS growth and adoption with a new set of businesses using software for the first time (full content available to Gartner clients). Cloud adoption is growing far quicker than other cloud technology segments, such as Platform- (PaaS) or Infrastructure-as-a-Service (IaaS) products.

4. Who owns my SaaS data?
In the vast majority of cases, you still own your data in a cloud-based system. Most service level agreements (SLAs) confirm your company’s ownership of your data located on the vendor’s servers, as well as your right to retrieve the data.

Most SaaS contracts also have built-in and prepaid contingencies that will provide access to your data if the vendor goes out of business (see below) and guarantees that you own that data.

Furthermore, most SaaS vendors will let you export your data and back it up locally any time you want. It’s very unusual for any vendor to insist that they retain ownership of your data. If you notice this in a clause, don’t sign the dotted line. This SLA is an important and fairly complex document that should be scrutinized with your stakeholders before committing to purchasing a new solution.

In addition to data ownership, be sure to carefully review these aspects of a SLA:

* Responsibilities of the software vendor for support, updates, or security
* Your responsibilities as a client to notify the vendor of issues in a timely manner
* Guarantees for service, such as level of uptime and how a customer can respond to poor service

5. Can I customize SaaS software?
Yes! Today’s web-based software is flexible enough to be modified for specific business uses but also individual users. Buyers can customize the user interface (UI) to change the look and feel of the program, as well as modify specific areas, such as data fields, to alter what data appears. Several business process features can also be turned off and on at will.

Users can often tweak their own personal workspace, such as a dashboard or task list, to show only the information they need to see and optimize their unique work style.

6. What are the internet and operating system (OS) limitations?
The primary downside of SaaS is that it relies on a good internet connection. But unless your business resides in a remote location, your connection will be more than sufficient to utilize today’s SaaS systems.

While many believe on-premise systems to be more reliable, no system is fully immune to downtime. On-premise software is subject to electrical outages, hardware failures, and a range of other risks. As a safeguard, some SaaS vendors have developed “offline” functionality that allows people to keep working in the event that the internet does go down. Once a solid connection is available again, all the data is synced to the system.

Beyond the internet connection, some buyers worry about compatibility with different operating systems. It’s unlikely you’ll need to consider OS compatibility—most are delivered via web browsers and are fully OS agnostic. At the most, you may need to download a different web browser that will work best for your SaaS system.

7. What is a private cloud?
A private cloud takes all of the infrastructure technology that runs a public cloud and stores it on-premise. Users achieve the same functionality and ability to access their data through a web browser. However, instead of sharing the computing power with the general public, the computing power is shared among users at one company.

Contrary to the quickly growing public cloud model (full content available to Gartner clients), a private cloud requires an IT department to perform maintenance and upkeep. Establishing your own private cloud can be costly and requires an investment in the infrastructure required to develop and maintain a cloud environment.

Private clouds also require large or complex projects to generate a return on investment. For large enterprises that don’t want to put their information in a publicly accessed cloud, it is an attractive option.
