Two weeks ago, at their first ever HashiConf, HashiCorp announced two new tools, Otto and Nomad. Both of these are great new tools but, Iʼm going to be concentrating on the former as Iʼm more interested in it. For the first time, HashiCorp is rethinking one of their current products, Vagrant.

I use Vagrant every day, its immensely useful. Its a great way to set up isolated and consistent development environments. All of that comes with a cost though. Setting up Vagrant is quite a bit of work. You have to figure out how to provision the environment. Vagrant has all of the standard choices built in, so, you can pick your favorite but, that requires you to have some existing knowledge. You could provision your environment using shell scripts but, that quickly gets painful. As this is a fairly large pain point, a variety of tools have sprung up in an attempt to fix this, such as Puphpet and Rove. For a while, I was really excited by this sort of thing. I almost built a community with Nathan Leclaire for hosting vagrant environments after he came up with the idea. Things didnʼt work as it was a really busy time for both of us. After quite a bit of thinking, Iʼm glad that we didnʼt. It just wasnʼt the right way to move things forward.

The other big problem with Vagrant is moving your app into production. You put in a lot of work to build your development environment but, theres a pretty good chance that youʼll need to put in a bunch more work to prepare your production environment. The quick setup that you do for setting up your development environment will not be sufficient for production. In a lot of ways, Vagrant seems to work better if youʼre working back from your production environment. Being able to replicate your exact production environment has lots of benefits but, if you donʼt already an existing set of scripts, roles, or modules then, using Vagrant is going to take a lot of setup to get going.

Thats where Otto comes in. Otto is HashiCorp rethinking how you should setup development environments. It can automatically detect the type of application that youʼre developing and it will build an appropriate development environment automatically. Of course, this leverages Vagrant under the covers, it just skips the laborious setup process. The other big thing that Otto provides is a way to move your application into production.

I think Otto is the answer to a question that Iʼve been pondering for quite some time: how should a small group of developers create and deploy an application? There arenʼt a whole lot of good options for small teams. Recently there have been an explosion of tools for simplifying managing application but, they seem to all be focussed on much larger teams and applications. Things like Mesos, kubernetes and Docker are all great but, they require quite a bit of knowledge to run. For a small team, theyʼre all are too much of a knowledge investment to be useful. Deploying to plain servers also requires too much knowledge to keep running and to secure. The only good option here is Heroku but, that isnʼt without its downsides. Heroku is extremely expensive for what it provides and it ties you to a proprietary platform.

Otto really fills this need. When it comes time to move your app into production, Otto will create industry standard infrastructure for you. This is very important as it allows many hard-earned lessons to automatically be handled. Iʼve felt that things like Chef roles and Puppet modules presented a similar opportunity but, both have fallen very short of that goal. This allows developers to get back to what they do best, improving your application.

As with most of HashiCorpʼs products, Otto is launching with a small set of functionality. The two main limitations are that the app types that Otto supports are rather limited and there is only one type of deployment that is available. Of course, both of these things will improve over time but, theyʼve kept me from being able to start using Otto. These days, Iʼm spending most of my time working in Clojure and Otto doesnʼt currently support jvm applications. In the current version, Otto only supports Docker, Go, PHP, Node, and Ruby but, those cover a large swath of developers. Otto also will only deploy to aws which I donʼt use due to the relatively high cost. I really want to use Otto but, its features are quite enough for me yet.

Otto is an important evolution of a crucial DevOps tool, Vagrant. It makes huge strides forward for many of the current use cases. It removes the biggest pain point of getting Vagrant up and running. It also fills a crucial need by providing a good way to move applications into production. I’m looking forward to using Otto in the future.
