How Heroku Operates its Multi-Tenant Apache Kafka Services

This blog post is adapted from a talk given by Ali Hamidi at  Data Council SF ’19  titled “ Operating Multi-Tenant Kafka Services for Developers on Heroku .”

Thousands of developers use  Heroku’s Apache Kafka service  to process millions of transactions on our platform—and many of them do so through our multi-tenant Kafka service. Operating Kafka clusters at this scale requires careful planning to ensure capacity and uptime across a wide range of customer use cases. With significant automation and test suites, we’re able to do this without a massive operations team.

In this post,…

VPN Support for Heroku Private Spaces

Today we're excited to announce Site-to-Site Virtual Private Network (VPN) support for Heroku Private Spaces . Heroku customers can now establish secure, site-to-site IPsec connections between Private Spaces on Heroku and their offices, datacenters and deployments on non-AWS clouds.

VPN is a powerful, proven and widely-adopted technology for securely combining multiple networks (or adding individual hosts to a network) over encrypted links that span the public Internet. VPN is well-understood and in use by most enterprise IT departments, and is supported on all major cloud providers and by a range of hardware and software-based systems.

Internal Routing for Private Space Apps

Today we’re announcing a powerful new network control for apps running in Heroku Private Spaces : Internal Routing. Apps with Internal Routing work exactly the same as other Heroku apps, except the web process type is published to an endpoint that’s routable only within the Private Space and on VPC and VPN peered networks (see the Private Space VPN support companion post ). Apps with Internal Routing are impossible to access directly from the public internet, improving security and simplifying management and compliance checks for web sites, APIs and services that must not be publicly accessible.

Kafka Streams on Heroku

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…

How Combatant Gentlemen Solved Service Discovery Using Heroku Private Spaces

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…

Microservices in Go using Go-kit

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…

Why Microservices, Decomposing Big Projects, Matter

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…
