At Heroku, we're always working towards increased operational stability with the services we offer. As we recently launched the beta of Apache Kafka on Heroku, we've been running a number of clusters on behalf of our beta customers. Over the course of the beta, we have thoroughly exercised Kafka through a wide range of cases, which is an important part of bringing a fast-moving open-source project to market as a managed service. This breadth of exposure led us to the discovery of a memory leak in Kafka, having a bit of an adventure debugging it, and then contributing a patch…
So you want to build an app with React? "Getting started" is easy… and then what? React is a library for building user interfaces, which comprise only one part of an app. Deciding on all the other parts — styles, routers, npm modules, ES6 code, bundling and more — and then figuring out how to use them is a drain on developers. This has become known as javascript fatigue. Despite this complexity, usage of React continues to grow. The community answers this challenge by sharing boilerplates. These boilerplates reveal the profusion of architectural choices developers must make. That official "Getting…

Today we're announcing two new features that will help you better manage and run apps on Heroku: Threshold Alerting and Hobby dyno metrics. Threshold Alerting provides the ability to set notification thresholds for key performance and health indicators of your app. We’ve also extended basic Application Metrics to Hobby dynos to provide basic health monitoring and application guidance. Together these features allow you to stay focused on building functionality by letting the platform handle your app monitoring. Threshold Alerting There are many ways to measure the health of an application. The new alerting feature focuses on what is most important…

Redis might sound like it’s just a key/value store, but its versatility makes it a valuable Swiss Army knife for your application. Caching, queueing, geolocation, and more: Redis does it all. We’ve built (and helped our customers build) a lot of apps around Redis over the years, so we wanted to share a few tips that will ensure you get the most out of Redis, whether you’re running it on your own box or using the Heroku Redis add-on. Use a Connection Pooler By using a connection pooler, you'll reduce the connection overhead and therefore speed up operations while reducing…

Scott Raio is Co-Founder and CTO of Combatant Gentlemen], a design-to-delivery menswear e-commerce brand. What microservices are you running in Heroku Private Spaces? We’ve written an individual service for every business use case. For example, we have services for order processing, product catalog, account management, authentication, swatch display, POs, logistics, payments, etc. With all these different services, we chose Heroku Private Spaces as a way to make service discovery easier. We’re currently running about 25 services, which is a relatively small number compared to Netflix or Twitter (who employ hundreds of services). But we’re growing, and we’re always evaluating our…

We recently launched Apache Kafka on Heroku into beta. Just like we do with Heroku Postgres, our internal engineering teams have been using our Kafka service to power a number of our internal systems. The Big Idea The Heroku platform comprises a large number of independent services. Traditionally we’ve used HTTP calls to communicate between these services. While this approach is simple to implement and easy to reason about, it has a number of drawbacks. Synchronous calls mean that the top-level request time will be gated by the slowest backend component. Also, internal API calls create tight point-to-point couplings between…
