2X Dynos in Public Beta

A dyno, the unit of computing power on Heroku, is a lightweight container running a single user-specified command. Today we’re announcing a dyno with twice the capacity: 2X dynos.

2X Dynos

Existing dynos are now called 1X dynos. They come with 512MB of memory and 1x CPU share. They cost $0.05/hr. 2X dynos are exactly what their name implies: 1GB of memory and twice the CPU share for $0.10/hr. To support the growth of current and future apps on the platform, you can now control your dyno resources on two axes: size and quantity.

Let’s try them out.

Getting started with 2X dynos

Using the Heroku Toolbelt, resize your dynos with the resize command:

$ heroku ps:resize web=2X worker=1X Resizing...

Heroku Postgres Databases Patched

Heroku Postgres Databases have been patched

Data is one of the most valuable assets of any company. As a database-as-a-service provider, one of our biggest responsibilities is ensuring your data is kept safe. A few weeks ago, one of the worst security vulnerabilities to date in PostgreSQL was discovered. To address this issue, Heroku deployed a point release upgrade across the entire Heroku Postgres service earlier this week. This resulted in a period of database unavailability, typically with a duration of less than one minute. Every database running on Heroku Postgres is now appropriately patched and is unaffected by the vulnerability.

Routing and Web Performance on Heroku: a FAQ

Hi. I'm Adam Wiggins, cofounder and CTO of Heroku.

Heroku has been my life’s work. Millions of apps depend on us, and I take that responsibility very personally.

Recently, Heroku has faced criticism from the hacker community about how our HTTP router works, and about web performance on the platform in general. I’ve read all the public discussions, and have spent a lot of time over the past month talking with our customers about this subject.

The concerns I've heard from you span past, present, and future.

The past: some customers have hit serious problems with poor web performance and insufficient visibility on their apps, and have been left very frustrated as a result. What...

Helios - open source framework for mobile

Heroku has a strong tradition with open source projects. Engineers have dedicated countless hours to the projects that developers count on every day. Open Source Software is in our DNA.

Speaking personally, I’m passionate about building tools like AFNetworking and cupertino, in order to help developers build insanely great experiences for mobile devices. It’s with great pleasure that I introduce something new I’ve been working on:

Helios is an open-source framework that provides essential back-end services for iOS apps. This includes data synchronization, push notifications, in-app purchases, and passbook integration. It allows developers to get a client-server app up-and-running while...

Waza 2013: How Ecosystems Build Mastery

When we think of the concept of Waza (技) or "art and technique," it's easy to get caught up in the idea of individual mastery. It's true that works of art are often created by those with great skill, but acquiring that skill is neither solitary nor static. Generations of masters contribute to a canon and it is in that spirit that we built the Heroku platform and the Waza event. This year's Waza was no exception.

On February 28th, more than 900 attendees participated in Waza including Ruby founder Yukihiro "Matz" Matsumoto, Django co-creator Jacob Kaplan-Moss and Codeacademy’s Linda Liukas. True to form, we offered you a platform for experimentation and...
