What is Composable SaaS? Future of Modular Software

In the past, businesses utilized big monolithic software products aimed at performing all business activities. Although the all-in-one solution had initial advantages for enterprises, the inflexibility of the system caused long development cycles and vendor lock-in problems. 

The modern rapidly growing business is shifting towards plug-and-play digital ecosystems. The concept of what is composable SaaS explains how modular software architectures define the future of cloud computing. 

Understanding the Basics: What Is Composable SaaS? 

Composable SaaS is the approach to software architecture that involves building platforms out of independent and specialized components that are linked with each other via API. 

Imagine this approach as a Lego-like construction; instead of purchasing one big solution, businesses will be able to buy the best-of-breed applications for payment processing, search, analytics, content management, and more. Key aspects of the approach include:

• Modular Business Capabilities: Independently running microservices performing individual operations such as checkout or user authentication.
• API-first Communication: Standards for communication between different software products to exchange data. 
• Headless Architecture: Detaching the user experience layer from the database layer of the platform.

Why Modular Apps Are Outpacing Monolithic Systems

Classic software bundles fail to meet changing market expectations since updating one component could possibly break down the whole software. The use of a composable architecture resolves all the above challenges.  Some benefits of composable applications are:

• Best-in-Class Platforms: Businesses choose the best-performing platforms for each individual component instead of choosing average pre-bundled modules. 
• Scale by Functionality: Developers scale high-transaction components such as a recommendation engine without scaling the whole application.
• Getting rid of vendor lock-in: Businesses replace outdated components without going through a disruptive application rewrite.

Advantages of Flexible SaaS Systems for Business

Flexibility of SaaS solutions allows companies to be innovative and decrease technological risks.

• Quick Delivery of Products: Teams deliver, test, and improve innovations on digital features within a few days instead of waiting several months for updates of the platform.
• Painless Modernization: Old systems can be modernized gradually with the help of replacing one troublesome module after another.
• Improved Application Stability: In case any single API module faces some issues, other components keep working properly.

Conclusion

A trend to use modular apps is the final stage of software development. The knowledge of what is composable SaaS proves the reason for leaving monolithic systems behind. Modular cloud software provides flexibility for changing the software quickly and integrating new technology tools.
