SaaS helps organizations to start functioning smoothly without the burden of setting up all software infrastructure from scratch. Over the years, we have published a lot of content on SaaS and related topics. This SaaS omnibus aims to bring you all of those valuable, informational content together so that you can access it all from a one-stop solution. Each section is linked to a detailed blog where you can find more information about the said topic. Here's what you need to know about SaaS. Let's start from the basics.
What is SaaS?
SaaS, the short form for software as a service, is an internet-based software delivery model where users can access and software services via a browser. The software is centrally hosted in the service provider's data center and accessed in a subscription framework. With SaaS, customers don't have to install the software on their devices or update them from time to time – the SaaS provider is responsible for the smooth running of the application on devices.
Differentiating SaaS, PaaS, and IaaS
When enterprises decide on switching operations to the cloud, it is essential to understand the various cloud models and services and what they do. Knowing the differences between each of them will help in finding the right solution for the company. There are many as-a-service models in the market now. But, the most prominent ones are:
- Software as a Service (SaaS) - uses the cloud/internet to deliver applications to users. These applications are hosted and managed by a third-party provider.
- Platform as a Service (PaaS) - offers frameworks for developers to build upon and is used to create custom applications. The enterprise or a third-party provider manages all the servers, storage, and networking while developers manage the applications and data.
- Infrastructure as a Service (IaaS) - enables enterprises to purchase infrastructure resources on-demand instead of buying the hardware. The cloud servers included within IaaS are typically provided to the company through a dashboard or an API. The client gets control over the applications, data, middleware, operating system, and runtime.
How Do Web Applications Work?
Web applications, especially SaaS, work through web browsers. They require three significant components – web servers to handle requests from the client, app servers to execute the input, and data servers to store the information. The server-side and client-side programming are often done in different programming languages and are integrated to form user-friendly interfaces for the parties involved. Here is a look at the steps involved in the function of web apps.
- The user creates requests through the app's interface
- The request is sent to the app server
- App server executes the request sends the processed data to the web server
- The user gets the processed request on their interface from the web server.
Types and Examples of SaaS
SaaS applications can be of various types – they can be personal or organizational in nature. Some examples of SaaS are:
- Email/messaging services
- Calendaring/office software
- Enterprise resource planning (ERP)
- SaaS Accounting
- Project Management
- Human resources management (HRM)
- Geographic information systems (GIS)
- Virtualization
- CAD software.
Common Characteristics of SaaS Applications
Even though most SaaS applications differ from each other in many aspects, there are some common characteristics. Here are some of the common elements.
- Configuration and customization
- Open integration protocols
- Accelerated feature delivery
- OpenSaaS
- Collaboration and sharing
SaaS Security Best Practices
For many, SaaS security means that it's just about the threats a user faces while accessing the web. But, it means much more than that for both providers and customers. Most security requirements and best practices vary from industry to industry and company to company, but there are some common characteristics. Here is a glance at six best practices to follow in ensuring SaaS security.
- Know your provider
- Advanced authentication procedures
- Data encryption
- Keep usage inventory
- Constant monitoring
- External support resources (if needed)
Using SaaS to Enhance Growth
If you are a SaaS company or are planning to be one, this is probably a good time to operate. But, to run your SaaS business successfully, there are certain considerations companies can follow:
- Know your target well
- Focus on customer experience
- Using SaaS marketing effectively
- Plan integrations in advance
- Know your architecture
- Form a suitable pricing strategy
SaaS Testing
Based on business workflows and other parameters such as configurations, non-functional requirements, integrations, and data, SaaS testing validates the applications. With successful SaaS testing starting early in the development lifecycle, it has a broader scope in the damaged areas, and teams continue to test as upgrades and patches come by.
There are a few elements that can work as the basis of successful SaaS testing.
- Application – ensure business workflows, integrations, data security, and other requirements are considered and on track.
- Ensure accurate and secure data transfer between the SaaS and the client
- Infrastructure – disaster recovery protocols and regulatory compliance must be ensured
