Expanded HTTP Method Support

HTTP and its secure variant, HTTPS, are the protocols used by every web client to talk to web applications. A key part of the protocol is the HTTP method. Traditionally, web applications used a very limited set of HTTP methods. It is common for application servers, proxies and routers (such as the Heroku HTTP router) to prevent unknown methods from being used. This unnecessary constraint of the Heroku HTTP router has increasingly become a limitation to developers building modern web applications. In the past, if you tried to use an unsupported HTTP method in your Heroku application, clients would receive…

Postgres Version 9.2 is now Default

Over a year ago we began working with the community as to how we could help to make Postgres better. Much of this came to fruition with PostgreSQL version 9.2 and three months ago we released support of Postgres 9.2 into GA. We've now seen many users begin taking advantage of the powerful features in this version including: Better visibility with pg_stat_statements URL support JSON datatype and more In these three months the 9.2 PostgreSQL version has had time to bake including several minor updates fixing a variety of bugs.

Empowering Change: Programming Literacy for All

There has never been a better time to be a programmer. Every day more and more gadgets get connected or over-clocked. Programming is so prevalent that it often goes unnoticed in our daily lives. Whether we're scripting out social presence with IFTTT, or doing taxes with Excel, automation and programming has become an inescapable part of the modern world. Heroku believes that to invest in our future, we must invest in programming literacy. While we're waiting for recursion to be a staple in our children’s classrooms, we can work on continuing and higher education today. Heroku engineers are given opportunities…

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. 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…

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…

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…
