Software as a Service Definition
With SaaS customers can use software products by subscribing to them online. The application itself, along with its code, servers and database is maintained by software providers like Amazon Web Services or Google Cloud. Users can then simply access the software through a web browser or a mobile app.

How does Software as a Service actually work?
It involves two steps: first a vendor develops the software; then customers use the software.
The vendor creates software to address business needs or challenges.
They often gather requirements from customers. Aim to solve multiple users’ problems simultaneously.
This approach allows vendors to offer benefits such as flexibility and reduced maintenance, for their clients.
In return customers pay for the product overtime (through a subscription) with the expectation that their feedback will contribute to improvements.
It’s important to note that customers do not own the software themselves but enjoy the convenience of not having to worry about its maintenance.
Core Benefit of Software as a Service
The benefits of SaaS present an alternative approach of software installation, which often entails setting up a server, installing the program and configuring it on site.
When it comes to Software as a Service, these products are hosted on a cloud network that users can access either through the internet or via an API.
One of the differences between SaaS and traditional software models is that SaaS products come preconfigured.
Advantages of Software as a Service
The advantages of using the SaaS model for obtaining software are as follows:
Firstly, installation costs are significantly reduced since SaaS products can be installed with a few clicks.
For software, the time taken for end users to start benefiting from it is reduced because there’s no need to set up servers.
All that’s required is the data, which is typically provided by the user, customer or API.
Additionally, maintaining and updating software becomes more cost effective for users. The vendor takes care of all installations and software updates.
Then applies those changes globally. As a result, the software periodically gains features with effort required from the user.
Furthermore, scalability and integration are strengths of this model.
The software is built on third party vendors like AWS (Amazon Web Services) which allows it to scale based on demand. This means that during spikes in usage, the software is unlikely to experience any disruptions.
Challenges of Software as a Service
Consideration before Commitment
Before committing to SaaS provider, it’s important to consider aspects such as customer support and data security.
Understanding the risks and drawbacks associated with SaaS can help you determine if it’s the choice for your organization.
Lack of control and SLA arrangements
When it comes to you using a SaaS product, you won’t have control over its programming.
Any necessary fixes will depend on the details specified in your SLA. Unless you decide to deviate from the SLA you might not have say in handling any issues with your software using your in-house engineers.
Issues with software integration
While initially outsourcing tasks to a vendor might seem easier, in the long run you could become reliant on the vendor’s support team.
This dependency can negatively impact your reputation with customers.
If your software is integrated with a SaaS and any downtime affects your customers adversely, they will hold you accountable not the vendor.
Key Features of Software as a Service
When discussing your requirements for developing a SaaS application with companies make sure to address the following characteristics:
Accessibility:
SaaS applications should be available globally for users, around the world.
Given that they’re accessible to residents, it is crucial for them to be available around the clock without any interruptions.
Multi-tenant Model:
The multi occupancy model is a software design that allows you to provide services to individuals using a software system.
Security:
Encrypted storage should be provided to store data for a resident, which should not be accessible to residents.
Adaptable Framework:
Anticipating the usage of SaaS application management can be challenging. That’s why it is crucial to have an infrastructure that can expand, or contract based on resource requirements.
Single Sign-On:
Organizations need an identity system that allows users to log in using their credentials and access the service. Single Sign-On verifies the existing login system enabling users to authenticate and utilize the system.
