In today's fast-paced digital landscape, application modernization is crucial for businesses looking to stay competitive. One important aspect of modernizing your apps is following the principles outlined in the "12 Factor App," a methodology for building software-as-a-service applications. In this series of blogs, we're breaking down each of the 12 factors and explaining why they're important for achieving successful app modernization.
Today, we're looking at the 6th factor: processes.
When it comes to modernizing your applications, it's important to remember that the code is only one part of the equation. The processes you use to build, test, deploy, and run your apps are just as important. This is where the 6th factor comes in: processes.
The 12 Factor App states that apps should be "executed as one or more stateless processes." This means that each process should be independent and able to handle any incoming requests without relying on the state of other processes. This is especially important in today's cloud-based environments, where horizontal scaling is a common practice. By having stateless processes, you can easily add or remove resources as needed without disrupting the overall system.
Another key aspect of the 6th factor is that processes should be "disposable." This means they can be easily terminated and replaced without causing disruption to the rest of the system. This is particularly important in a DevOps environment, where rapid iteration and continuous deployment are crucial. By having disposable processes, you can quickly and easily roll out new updates and features without having to worry about the impact on existing processes.
In addition, processes should be "concurrent" as they allow for multiple requests to be handled simultaneously, improving the overall performance and scalability of the application.
So why is the 6th factor of the 12 Factor App so important for application modernization? By following these principles, you can ensure that your apps are built to handle the demands of today's digital landscape and are ready to scale as needed. It also helps to have a more stable and productive deployment process by reducing human error and downtime.
