I need to take a couple minutes here to do something I've been meaning to for along time: Thank Heroku for being so baller.
For those of you not in the know, Heroku is an all-in-one Ruby platform built on top of Amazon web services. If you're a Ruby developer, and you are creating a web application, I highly recommend checking it out.
I've been using Heroku on two applications, including JumpPost, which officially launched today via a nice writeup on the Thrillist NYC site and newsletter. I'd like to share a couple reasons why I love the Heroku platform and would advise any agile startup to consider using it to get their product launched quickly.
Heroku is fast
The same could be said for any well configured EC2 instance, but don't underestimate the words well configured. The smart folks at Heroku have fine tuned every layer of the stack from using the fastest web servers (nginx), caches (Varnish, Memcache), and load balancing strategies.
Heroku is scalable
At the core of Heroku's architecture is a pre-compiled version of your application called a "slug" which is ready to be deployed in seconds to as many instances as you desire. Expecting a big press hit, or noticing your request queue filling up, just type a simple command and add more resources in seconds. Your users won't even know.
Heroku is easy
To deploy you literally type one command at the command line. They provide add-ons for caching, email, DNS, performance monitoring, custom domains, etc…many of them free.
Heroku provides killer support
Not only does the staff respond to tickets and support requests within minutes, but they go overboard to support the latest and greatest Ruby features. They're very active on the newsgroup, and they even provide sample code for how to best utilize their architecture.
Heroku is cost-effective
People may argue me on this one, because at face value the cost is actually rather expensive (think 2x the regular price of AWS). But these people aren't taking into account the cost of their own time when it comes to sysadminning, troubleshooting, not the mention the cost of downtime. Heroku never goes down, and it eliminates the need to pay a sysadmin (or the time value of sysadminning yourself).
Heroku is beautiful
Don't believe me? Check out their pricing page (yes they know their demographic are samurai loving programmers). Navigating their site to manage add-ons, monitor performance, and scale up and down resources is a pleasure.
With all of the above, there are a couple downsides that people should be aware of. Proper SSL is expensive, and should your app face custom scaling needs or challenges then you are locked into their stack. Fortunately their stack is designed for large scale use. The Heroku folks are well aware of these concerns, and they're very open about what they're doing to improve the experience for all of their customers. For startups getting their product off the ground, the time savings early on far outweigh the cost of figuring out a custom solution later should your product achieve grand scale. In case you couldn't tell, I'm a big fan.
