Preview requirements are prerequisites for testing microservices in a larger application. These requirements ensure you're testing services in the right environment before deployment, allowing you to catch issues that users could face. There are many ways to preview microservices, but requirements help you better understand how updates could impact the application at large, representing the real-world experiences of end users.

Microservices is a unique organizational and architectural hierarchy used by many development companies. In the past, developers would work together to implement features until a monolithic service. While that worked in the early development days, a monolithic approach is no longer viable.

Software is more complex than ever, and developers must continually improve their applications to meet users' ever-changing needs. Microservices provide greater flexibility and resilience by having teams focus on specific services. Those microservices run independently and communicate via API, creating a segmented but cohesive application.

Kubernetes Preview Environments

There are many reasons to move to a microservices approach. You can avoid far-reaching issues due to problems with one feature. Plus, you can scale separate services up or down as needed. But one of the best things about having microservices is that you can use Kubernetes preview environments to test changes before you deploy them.

In the past, there was no real way to update software. Developers would create new features and stick them into new versions that users had to purchase separately. As development processes improved, we moved on to version upgrades.

But microservices take things further by allowing you to develop microservices separately. Think of it as having several pieces to a larger puzzle, and each piece represents a core feature or process of your bigger application.

You can work on those separate pieces individually to upgrade or enhance your application. Previewing environments allow you to test changes and upgrades in a real-world processing environment. See how your changes impact the application. Identify potential issues and continue to make improvements until things are just right.

Fine-tune microservices development and use preview environments to test changes before you officially deploy them to the masses.
