Evolving the Backend Storage for Platform Metrics

One of our most important goals at Heroku is to be boring. Don’t get us wrong, we certainly hope that you’re excited about the Heroku developer experience — as heavy users of Heroku ourselves, we certainly are! But, even more so, we hope that you don’t have to spend all that much time thinking about Heroku. We want you to be able to spend your time thinking about the awesome, mission-critical things you’re building with Heroku, rather than worrying about the security, reliability, or performance of the underlying infrastructure they run on. Keeping Heroku “boring” enough to be trusted with…

Global Expansion for Heroku Private Spaces: Canada, India, Singapore, and the United Kingdom

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 Data for Redis, Heroku Connect, and most Heroku Add-ons. Private Spaces provide a dedicated virtual network environment for…

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 does Heroku use them? All AWS…

The Adventures of Rendezvous in Heroku’s New Architecture

This article was originally authored by Srinath Ananthakrishnan, an engineer on the Heroku Runtime Networking Team Summary This following story outlines a recent issue we saw with migrating one of our internal systems over to a new EC2 substrate and in the process breaking one of our customer’s use cases. We also outline how we went about discovering the root of the issue, how we fixed it, and how we enjoyed solving a complex problem that helped keep the Heroku customer experience as simple and straightforward as possible! History Heroku has been leveraging AWS and EC2 since the very early…

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 burden of…

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 these…

Heroku Postgres via PrivateLink Is Now Generally Available

Today, we're thrilled to announce Heroku Postgres via PrivateLink, a new integration that enables customers to seamlessly and securely connect Heroku Postgres databases in Private Spaces to resources in one or more Amazon VPCs. Heroku Postgres via PrivateLink connections are secure and stable by default because traffic to and from Heroku Postgres stays on the Amazon private network; once a PrivateLink is set up, there is no brittle networking configuration to manage. As always, security and trust are top of mind with everything we do at Heroku. The ability to configure Heroku Postgres via PrivateLink is already enabled on all…

Managing Real-time Event Streams and SQL Analytics with Apache Kafka on Heroku, Amazon Redshift, and Metabase

Building a SaaS product, a system to handle sensor data from an internet-connected thermostat or car, or an e-commerce store often requires handling a large stream of product usage data, or events. Managing event streams lets you view, in near real-time, how users are interacting with your SaaS app or the products on your e-commerce store; this is interesting because it lets you spot anomalies and get immediate data-driven feedback on new features. While this type of stream visualization is useful to a point, pushing events into a data warehouse lets you ask deeper questions using SQL. 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. VPN support complements Private Space VPC…

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. Internal Routing unlocks several exciting new…
