Back in September 2023, we announced our Public Beta for our new Common Runtime router: Router 2.0.

Now generally available, Router 2.0 will replace the legacy Common Runtime router in the coming months, and bring new networking capabilities and performance to our customers.

The beta launch of Router 2.0 also enabled us to deliver HTTP/2 to our customers. And now, because Router 2.0 has become generally available, HTTP/2 is also generally available for all common runtime customers and even Private Spaces customers too.

We’re excited to have Router 2.0 be the foundation for Heroku to deliver new cutting edge networking features and performance improvements for years to come.

We are thrilled to announce that Heroku Automated Certificate Management (ACM) now supports wildcard domains for the Common Runtime!

Heroku ACM’s support for wildcard domains streamlines your cloud management by allowing Heroku’s Certificate management to cover all your desired subdomains with only one command, reducing networking setup overhead and providing more flexibility while enhancing the overall security of your applications.

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.

Introduction:

We’re excited to announce public beta support for HTTP/2 on both Heroku Common Runtime and Private Spaces. HTTP/2 support is one of the most requested and desired improvements for the Heroku platform. HTTP/2 is significantly faster than HTTP 1.1 by introducing features like multiplexing and header compression to reduce latency and therefore improve the end-user experience of Heroku apps.

Since 2023, we’ve been working on a large platform modernization of our Common Runtime router. This project will allow us to start delivering more modern networking for Heroku. With the majority of that work now complete, we’re excited to focus more on the future and new features.

Introduction

Heroku is excited to introduce nine new dyno types to our fleets and product offerings. In 2014, we introduced Performance-tier dynos, giving our customers fully dedicated resources to run their most compute-intensive workloads. Now in 2024, today's standards are rapidly increasing as complex applications and growing data volumes consume more memory and carry heavier CPU loads.

With these additional dyno types, we’re excited to enable new use cases on Heroku with enhanced compute and memory specifications. Some use case examples include real-time processing against big data/real-time analytics, large in-memory cache applications such as Apache Spark or Hadoop...

In May 2023, we announced our limited release of two new Heroku Private Spaces regions: India (Mumbai) and Canada (Montreal). This month, we’re announcing the full general availability of those two regions, along with new Heroku Private Spaces regions for the United Kingdom (London) and Singapore. This expansion enables customers to maintain greater control over where their data is stored and processed. These four new regions fully support Heroku Private Spaces, Heroku Shield Private Spaces, Heroku Postgres, Apache Kafka on Heroku, Heroku Key-Value Store, Heroku Connect, and most Heroku Add-ons.

Private Spaces provide a dedicated virtual network environment for running Heroku...

Heroku is excited to announce the addition of a third availability zone (AZ) for our Private Spaces product offering. Three availability zones make Private Space apps more resilient to outages. We’ve prioritized this improvement as part of our focus on mission-critical features to make the Heroku Platform even more reliable. The changeover to three availability zones is fully managed by Heroku. Heroku handles all maintenance, upgrades, and management of Private Spaces, so our customers can focus on delivering value to their users without worrying about the underlying infrastructure.

What are availability zones and how does Heroku use them?

All AWS regions have multiple availability...

This month, we’re expanding the Heroku platform with a limited release of our Private Spaces product in two new regions, India (Mumbai) and Canada (Montreal), enabling customers to maintain even greater control over where data is stored and processed. These two new regions will fully support Heroku Private Spaces, Heroku Shield Private Spaces, Heroku Postgres, Apache Kafka on Heroku, Heroku Key-Value Store, Heroku Connect, and most Heroku Add-ons.

Private Spaces provide a dedicated and virtual network environment for running Heroku applications. They are now supported in the following regions, with new regions highlighted in bold below:

Since April 2021, the Heroku Runtime team has been working to deploy upgrades to the infrastructure powering Common Runtime apps, and we’re excited to formally announce the performance improvements that customers are already seeing.

When this Changelog post was published in May introducing the changes, almost all Common Runtime apps had been migrated from what we internally called the “classic“ infrastructure to the new “sharded” architecture. In addition to performance enhancements, this migration is expected to result in lower latency across the platform.

Around 99.9% of customers didn’t have to make any changes to their Heroku apps to benefit from these upgrades, and dyno prices are...
