What Is Software As A Service (SaaS)?

Software as a Service (SaaS) is a software distribution model that allows cloud providers to host applications and make them available to end users over the Internet. This model allows independent software vendors (ISV) to hire third-party cloud providers to host their applications. Or, for a large company like Microsoft, the cloud provider can also be a software provider. SaaS is the umbrella term for subscription-based Software as a Service. SaaS applications are hosted by the provider and delivered to the customer over the internet. The vendor, often a large enterprise, handles all aspects of infrastructure, including hardware/software maintenance, capacity planning, and security.

How Does SaaS Work?

SaaS (Software as a Service) is a category of cloud computing that uses internet-based software to provide application or data storage. SaaS is certainly considered one of 3 essential categories of cloud computing, along with infrastructure as a service (IaaS) and platform as a service (PaaS). A variety of IT professionals, commercial enterprise customers, and private customers use SaaS applications. Products variety from non-public entertainment, together with Netflix, to superior IT tools. Unlike IaaS and PaaS, SaaS merchandise is regularly advertised to each B2B and B2C customer. Unlike IaaS and PaaS, SaaS products are frequently marketed to both B2B and B2C users.

Companies that use SaaS applications are not tasked with the setup and maintenance of the software, which means less time and money spent on IT. Users simply pay a subscription fee to gain access to the software, which is often a ready-made solution. The Saas model is a scalable, reliable, and cost-effective way to offer high-quality software solutions to customers. By deploying the software remotely, companies are not tasked with the setup and maintenance of the software.

SaaS Architecture

SaaS applications and services are typically multi-tenant, which means a single instance of the SaaS application will be running on the host servers. That single instance will serve each subscribing customer or cloud tenant. The application will run on a single version and configuration across all customers or tenants. Though different subscribing customers will run on the same cloud instance with a common infrastructure and platform, the data from different customers will still be segregated.

The SaaS application architecture is ideal for cloud-based software. Rather than having to maintain multiple instances for a single customer, SaaS allows an entire customer base to share the same instance of an application, with each customer using their unique data. This makes it easier for cloud service providers to make necessary changes across an entire user base.

SaaS Advantages

SaaS is a cost-effective and easy way to bring users the latest applications and updates. It removes the need for organizations to install and run applications on their computers or in their data centers. This reduces the cost of hardware acquisition, deployment, maintenance, and software licensing, installation, and support.

Flexible Payments: SaaS offerings can provide software, hardware, or support to a business at an affordable price. Rather than purchasing and installing that software, users can subscribe to a SaaS offering and pay for usage over time. This allows businesses with predictable recurring costs to exercise better budgeting and allow users greater flexibility during the subscription period.

• Scalable Usage: Cloud services like SaaS offer high Vertical scalability, which gives customers the option to access more or fewer services or features on-demand. This is ideal for businesses that need to rapidly scale in the near term, but don’t want to overpay for unused capacity that might be needed in the future. These systems can also be used as an interim solution while you wait for full-scale deployment of dedicated physical servers or other infrastructure components.
• Automatic updates: With SaaS, customers can be assured that their applications are always running on the latest software updates. Rather than buying new software, clients can depend on a SaaS issuer to routinely carry out updates and patch management pose. This further reduces the burden on in-house IT staff.
• Accessibility and persistence: Because SaaS applications are delivered over the internet, users can access them from any internet-enabled device and location. This includes smartphones, which are ideal for day-to-day tasks such as checking email and accessing calendars. Because most of these applications are web-based, there is no need to download them onto a laptop or other device.

SaaS Challenges and Risks

The benefits of SaaS include easy access to software, the fact that it is updated regularly and that the vendor is responsible for updating it, lower costs, and better customer service. SaaS also has potential risks and challenges as it requires relying on external vendors to deliver software, maintain the execution of that software, track and report accurate billing, and provide a secure environment for corporate data. To help minimize potential risks, organizations should conduct thorough due diligence before engaging with a vendor and during each phase of the relationship with that vendor.
