The idea of centralising the hosting of business applications has been around at least since the 1960s. In the 1990s, it evolved with the rise of the internet into Application Service Providers (ASPs), with third-party applications managed and hosted by an ASP vendor, but some software still required to be installed on users’ computers.
SaaS is an evolution of the ASP model, with vendors and suppliers managing their own software and no installation required because software is distributed instantaneously over the internet -- via the cloud. Cloud computing allows businesses to consume computing resources over the internet as a utility – in the same way they do electricity or water.
The SaaS-based cloud model now offers businesses significant efficiencies and cost savings, but a number of developments were necessary before SaaS could become a viable option:
- Increased access to high-speed internet connections. This has made standard internet connectivity speeds adequate for using SaaS applications. More widespread broadband connectivity has also made it easier for users to access services in different locations.
- Standardisation of digital technologies. Common protocols make it easier to share, integrate and scale cloud-based programs and services, as well as provide better user experiences in a multi-device environment.
- Growing popularity and usage of web-like interfaces. More and more users are happy to work in this way thanks to the familiarity, usability and simplicity of web-like environments.
- Rapid and widespread adoption of mobile devices.
- Growth of remote working. People want to be able to connect from anywhere, not just the office. SaaS solutions work well to meet this need.
Software-as-a-Service is now just one of several cloud computing solutions for business IT issues. Other ‘as-a-Service’ options include:
- Infrastructure as a Service (IaaS) where the provider hosts hardware, software, storage and other infrastructure component
- Platform as a Service (PaaS) which allows customers to develop, run, and manage applications without having to have the infrastructure associated with developing and launching an app
- Managed Software-as-a-Service (MSaaS) where IT professionals support and upkeep their applications
- Desktop-as-a-Service (DaaS) where virtual desktop infrastructure is outsourced to a third-party provider
- Database-as-a-Service (DBaaS) which allows users to access a database rather than download or host it themselves
- Security-as-a-Service (SECaaS) is where a service provider allows access to their security services as a subscription
- Everything as a service (XaaS) which is essentially all the ‘as-a-Service’ tools neatly packaged together.
Businesses cite many reasons for turning to cloud-based SaaS solutions, including increased efficiency and cost-effectiveness, along with scalability, remote access to services, and automatic updates.
The benefits of SaaS include:
- Low setup and infrastructure costs
- Accessible from anywhere
- Rapid implementation
- Industry-leading service level agreements
- Automatic, frequent updates
Security is managed by the vendor. When selecting a vendor choose one who has all the necessary security accreditation and a proven track record.
At Salesforce, trust is our #1 priority. Data is one of the most valuable assets that each one of our customers possesses. Because we’re committed to providing secure access for our customers, we spend an incredible amount of time and resources on a world-class data security program.

With SaaS that there is no dedicated hardware or software to buy, install, maintain or update – so as a customer there’s little to see until normal day-to-day work begins.
Here are some common features of SaaS services.
- Multi-tenancy cloud architecture, so that all users and applications share a common infrastructure that is centrally maintained.
- Simple access via any connected device, making it easier to access data and information and keep data in sync.
- Familiar web-based interfaces, building on the consumer web that users already know. (This can help boost adoption and take-up rates.)
- Collaborative and social functions, which allow people in different teams or locations to collaborate effectively.

Back in the days of traditional client-server software packages, technology trends favored large enterprises. That’s because they entailed a big, expensive cash commitment upfront, backed by a staff of in-house IT professionals for implementation, maintenance, and security. Very few SMBs had resources for those kinds of purchases, and those that did often preferred to avoid such large expenditures.
SaaS is a game changer for small businesses. By making day-to-day infrastructure needs into a monthly operational expense that can be scaled up or down as an organisation’s needs evolve, many SMBs can now afford technology upgrades that were previously unavailable to them.
For example, the ability to outsource the provision and management of key functions enables a growing team to focus on its core skills. Rapid set-up, minimal up-front costs, remote working support and scalability are all obvious benefits, too.
At the other end of the scale, SaaS has also become a practical approach for enterprise-scale solutions too. Bringing together functions in a common environment or platform helps an enterprise gain scale, cost, speed and service efficiencies.
Enterprise-scale businesses often have different units operating across different territories, time zones and locations. Cloud-based SaaS can provide the tools to maintain a holistic, connected way of working in spite of these challenges, and in a cost-effective way.
With the right setup, legacy systems can also be plugged in to ensure that all a organisation’s services are interlinked. This helps eradicate gaps in reporting and data, forging a virtuous circle. In addition, teams can collaborate via shared social spaces that are always in sync on every user’s device.
The rising tide of software as a service has created an industry of products and services that require subscription-like recurring payments. This means the mindset of customers has also shifted from one-off customers with a one-time purchase, they become present customers that adopt a recurring purchase routine.
In response to this trend, Gartner predicts that by 2020 over 80% of software vendors will change their business model from traditional license and maintenance to subscription.
With the demand for high-volume data, software performance and backup increasing daily, businesses are likely to increasingly outsource IT activities to specialist service providers.
Businesses who are already fully invested in SaaS are likely to adopt integrated, end-to-end solutions that allow them to concentrate on what they do best. As a result, long-term relationships with service providers will grow – which in turn will lead to greater innovation as customers' growing needs are better understood and provided for.
