Expanded Memory and Compute with Heroku’s New Larger Dynos

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…

Heroku Cloud Native Buildpacks: Bringing Heroku Magic to Container Images

At Heroku, we believe the best choices are the ones you don’t have to make. That’s why we’re thrilled to announce the preview release of Heroku Cloud Native Buildpacks . Our Cloud Native Buildpack (CNB) offering brings the beloved Heroku language and framework experience to your local machine and beyond.

Heroku Adds Third Availability Zone for Private Spaces

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…

Faster Dynos and Improved Performance For All

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,…

Connection Pooling for Heroku Postgres Is Now Generally Available

We are excited to announce that we are moving Connection Pooling for Heroku Postgres into GA. Connection Pooling unlocks the ability to use up to 10,000 client connections to a Heroku Postgres Database, without adversely impacting performance on the database. This will unlock more complex and higher scale applications with simpler architectures on the Heroku Platform.

Over the years, one of the factors that you have to consider when scaling applications is pressure on the database. Each connection to the database consumes resources that could be spent on processing requests. The balancing of resources spent…

Making Time to Save You Time: How We Sped Up Time-Related Syscalls on Dynos

I work on Heroku’s Runtime Infrastructure team, which focuses on most of the underlying compute and containerization here at Heroku. Over the years, we’ve tuned our infrastructure in a number of ways to improve performance of customer dynos and harden security.

We recently received a support ticket from a customer inquiring about poor performance in two system calls (more commonly referred to as syscalls) their application was making frequently: clock_gettime(3) and gettimeofday(2) .

In this customer’s case, they were using a tool to do transaction tracing to monitor the performance of their application. This tool made many such system calls to measure…

Bring Your Own Key for Heroku Managed Data Services Is Now Generally Available

Security is always top of mind for Heroku customers; COVID-19 has further increased the urgency for enterprises and developers to deliver more mission-critical applications with sensitive and regulated data.

Given the needs of our customers, including those in regulated industries like Health & Life Sciences and Financial Services, we are thrilled to announce that Heroku Private Spaces and Shield customers can now deploy a new Postgres, Redis, or Apache Kafka service with a key created and managed in their private AWS KMS account. With BYOK, enterprises gain full data custody and data access control without taking on the…

Building and Scaling a Global Chatbot using Heroku + Terraform

Text-based communication has a long history weaved into the evolution of the Internet, from IRC and XMPP to Slack and Discord. And where there have been humans, there have also been chatbots: scriptable programs that respond to a user’s commands, like messages in a chat room.

Chatbots don't require much in terms of computational power or disk storage, as they rely heavily on APIs to send actions and receive responses. But as with any kind of software, scaling them to support millions of user’s requests across the world requires a fail-safe operational strategy. Salesforce offers a Live Agent…

Terrier: Open-Source Tool to Identify and Analyze Container and Image Components

As part of our Blackhat Europe talk “Reverse Engineering and Exploiting Builds in the Cloud” we publicly released a new tool called Terrier.
Announcing Terrier: An open-source tool for identifying and analysing container and image components.
In this blog post, I am going to show you how Terrier can help you identify and verify container and image components for a wide variety of use-cases, be it from a supply-chain perspective or forensics perspective. Terrier can be found on Github .

Containers and images

In this blog post, I am not going to go into too much detail about containers and…

Announcing Heroku Data Services Integrations Using mutual TLS and PrivateLink

Today, we’re thrilled to announce four new trusted data integrations that allow data to flow seamlessly and securely between Heroku and external resources in public clouds and private data centers:

Heroku Postgres via mutual TLS
Heroku Postgres via PrivateLink
Apache Kafka on Heroku via PrivateLink
Heroku Redis via PrivateLink

These integrations expand Heroku's security and trust boundary to cover the connections to external resources and the data that passes through them. They enable true multi-cloud app and data architectures and keep developers focused on delivering value versus managing infrastructure. Data is the driving force in modern app development, and…
