Best Practices for Optimizing Your Enterprise Cloud Applications with New Relic

If your cloud application performs poorly or is unreliable, users will walk away, and your enterprise will suffer. To know what’s going on inside of your million-concurrent-user application (Don’t worry, you’ll get there!), you need observability. Observability gives you the insights you need to understand how your application behaves. As your application and architecture scale up, effective observability becomes increasingly indispensable.

Heroku gives you more than just a flexible and developer-friendly platform to run your cloud applications. You also get access to a suite of built-in observability features. Heroku’s core application metrics, alerts, and language-specific runtime metrics offer a comprehensive view of your application’s performance across the entirety of your stack. With these features, you can monitor and respond to issues with speed.

Electron on Heroku

As maintainers of the open source framework Electron, we try to be diligent about the work we take on. Apps like Visual Studio Code, Slack, Notion, or 1Password are built on top of Electron and make use of our unique mix of native code and web technologies to make their users happy. That requires focus: There’s always more work to be done than we have time and resources for. In practice, that means that we don’t want to spend time thinking about the server infrastructure for the project‌ — ‌and we’re grateful for the support we receive from Heroku, where we can host load-intensive apps without worrying about managing the underlying infrastructure. In this blog post, we’ll take a look at some of the ways in which we use Heroku.

Simplify Your Cloud Security: Heroku ACM Now Supports Wildcard Domains

This highly-requested feature request is here, and in this blog post, we'll dive into what wildcard domains are, why you should use them, and the new possibilities this support brings to Heroku ACM.

Testing a React App in Chrome with Heroku CI

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.

Updating Twelve-Factor: A Call for Participation

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 …
