Designing scalable, fault tolerant, and maintainable stream processing systems is not trivial. The Kafka Streams Java library paired with an Apache Kafka cluster simplifies the amount and complexity of the code you have to write for your stream processing system.

Unlike other stream processing systems, Kafka Streams frees you from having to worry about building and maintaining separate infrastructural dependencies alongside your Kafka clusters. However, you still need to worry about provisioning, orchestrating, and monitoring infrastructure for your Kafka Streams applications.

Heroku makes it easy for you to deploy, run, and scale your Kafka Streams applications by using supported...

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...

Based in Budapest, Hungary, Andras Fincza (Head of Engineering) and Rafael Ördög (Technical Lead) work for Emarsys, a global marketing automation platform. Read our Emarsys customer story to learn more about their migration experience on Heroku.

How did you introduce microservices at Emarsys?

We take an evolutionary approach to our architecture. Our marketing automation platform was originally designed as a monolithic system built in PHP and MySQL and running on in-house infrastructure. We were running two major services on our in-house infrastructure: one for HDS (historical data service) and the other for smart insights and analysis. However, it was hard to grow the platform...

Go-kit is a distributed programming toolkit for building microservices. It solves the common problems encountered while building distributed systems, so you can focus on your business logic. This article starts with a bit of background on microservices, then guidance on how to get started with Go-kit, including instructions on getting a basic service up and running on Heroku.

A Brief Intro to Microservices

Traditionally, web applications are built using a monolithic approach where the entire application is built, designed, deployed and maintained as a single unit. When working with a monolithic application various problems can arise over time: it’s easy for abstractions to leak across...

All successful applications grow more complex over time, and that complexity creates challenges in development. There are two essential strategies to manage this problem: a team can keep everything together (create a monolith) or a team can divide a project into smaller pieces (create microservices).

The monolith at its most extreme is a single code base that contains all of an application’s logic and to which all programmers involved contribute. This approach is perhaps the most natural, and organic growth often tends towards this model. It’s also, in many ways, the easiest to reason about and operate. A single codebase can reduce many of the costs involved in distributed systems....
