When building web applications, unit testing your individual components is certainly important. However, end-to-end testing provides assurance that the final user experience of your components chained together matches the expected behavior. Testing web application behavior locally in your browser can be helpful, but this approach isn’t efficient or reliable, especially as your application grows more complex.

Ideally, end-to-end tests in your browser are automated and integrated into your CI pipeline. Every time you commit a code change, your tests will run. Passing tests gives you the confidence that the application — as your end users experience it — behaves as expected.

Over a decade ago, Heroku co-founder Adam Wiggins published the Twelve-Factor App methodology as a way to codify the best practices for writing SaaS applications. In that time, cloud-native has become the default for all new applications, and technologies like Kubernetes are widespread. Best-practices for software have evolved, and we believe that Twelve-Factor also needs to evolve — this time with you, the community.

Originally, the Twelve-Factor manifesto focused on building deployable applications without thinking about deployment, and while its core concepts are still remarkably relevant, the examples are another story. Industry practices have evolved considerably and many of the...

Compliance Is Possible with the Right Provider

Because today’s companies operate in the cloud, they can reach a global audience with ease. At any given moment, you could have customers from Indiana, Indonesia, and Ireland using your services or purchasing your products. With such a widespread customer base, your business data will inevitably cross borders. What does this mean for data privacy, protection, and compliance?

If your company deals with customers on a global — or at the very least, multi-national — scale, then understanding the concept of data residency is essential. Data residency deals with the laws and regulations that dictate where data must be stored and managed....

Modern applications have an unceasing buzz of user activity and data flows. Users send a flurry of one-click reactions to social media posts. Wearable tech and other IoT sensors work nonstop to transmit event data from their environments. Meanwhile, customers on e-commerce sites perform shopping cart actions or product searches which can bring immediate impact to operations. Today’s software organizations need the ability to process and respond to this rich stream of real-time data.

That’s why they adopt an event-driven architecture (EDA) for their applications.
