Electron on Heroku

As maintainers of the open source framework Electron, we try to be diligent about the work we take on. Apps like Visual Studio Code, Slack, Notion, or 1Password are built on top of Electron and make use of our unique mix of native code and web technologies to make their users happy. That requires focus: There’s always more work to be done than we have time and resources for. In practice, that means that we don’t want to spend time thinking about the server infrastructure for the project‌ — ‌and we’re grateful for the support we receive from Heroku, where…

Heroku Shield for Redis Is Now Generally Available

We are thrilled to announce that Heroku Shield for Redis is now generally available and certified for handling PHI, PII, and HIPAA-compliant data. Heroku Shield for Redis is the final missing data service for Heroku Shield, which is an integrated set of Heroku services with additional security features needed for building high compliance applications. All Heroku Managed Data Services — Heroku Connect, Heroku Data for Redis, Heroku Postgres, and Apache Kafka on Heroku — are now fully certified for handling PHI, PII, and HIPAA-compliant data as part of Heroku Shield. Security and compliance come standard with Heroku Shield, so developers…

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…

Up to 75% Faster Maintenances with Heroku Postgres and Redis Premium Plans

As outlined in a previous blog post, Heroku Data services undergo routine maintenances for security and patching. In this post, we describe the process used to minimize downtime for Heroku Postgres and Heroku Redis premium ‘High Availability’ plans and how we optimized the process to perform up to 75% faster. Data Services Architecture High availability plans for Postgres and Redis are designed to have two database instances running at the same time. One is a writeable primary database server and the other is a read-only hidden standby. Since the standby is hidden, customers cannot access it during normal operations. Before…

Why Frequent Maintenances Are Essential for Secure Heroku Data Services

There are many reasons to choose Heroku Data services, but keeping the services you use secure and up-to-date rank near the top. This foundation of trust is the most important commitment we make to our customers, and frequent and timely maintenances are one way we deliver on this promise. We do everything we can to minimize downtime, which is typically between 10 – 60 seconds per maintenance. There are ways for you to minimize disruption too (see the tips and tricks below). The rest of the post explains how we think about Heroku Data maintenances, how we perform them, and…

Optimizing Database Performance in Rails

Setting up a database is a relatively straightforward process (Heroku has an add-on for that), but getting it to run well in production is sometimes another matter. As your application grows and your data grows along with it, you will likely find a number of performance bottlenecks specifically related to your database, and this post aims to help you diagnose and address those issues when they arise. As with all components of your infrastructure it’s important to have early visibility into the performance characteristics of your database. Watching this data as your application grows will give you a much better…

Rolling the Heroku Redis Fleet

Over the past few weeks, Heroku proactively updated our entire Redis fleet with a version of Redis not vulnerable to CVE-2018-11218. This was an embargoed vulnerability, so we did this work without notifying our customers about the underlying cause. As always, our goal was to update all Heroku Redis instances well before the embargo expired. As a Data Infrastructure Engineer at Heroku, I wanted to share how we manage large fleet operations such as this one. The most important aspect of our job is keeping customers safe from security vulnerabilities, while also minimizing disruption and downtime. Those two objectives are…

An Update on Redis Vulnerabilities and Patching

On May 10, 2018, we received notice about two critical vulnerabilities in Redis, both embargoed until this morning. Upon this notice, our Data Infrastructure team proceeded to patch all internal and customer databases in response to these vulnerabilities. As of today, all customer databases have been patched successfully. At Heroku, customer trust is our most important value – and we are grateful to have your trust in keeping a globally-distributed data fleet safe from harm. If you’re interested in more behind the scenes details, check out our engineering blog post on how our Data Infrastructure team undertook the effort to…

Hello RedBeat: A New Celery Beat Scheduler

The Heroku Connect team ran into problems with existing task-scheduling libraries. Because of that, we wrote RedBeat, a Celery scheduler that stores scheduled tasks and runtime metadata in Redis. We’ve also open-sourced it so others can use it. Here is the story of why and how we created RedBeat. Why We Created the RedBeat Celery Scheduler Heroku Connect makes heavy use of Celery to synchronize data between Salesforce and Heroku Postgres. Celery is an asynchronous task queue that lets us schedule and queue jobs for execution by a background worker process. Over time, our usage has grown, and we came…
