Currently there are several options for hosting Clojure web apps.
However, if your web app needs SSL support on custom domain you immediately need to pay $20/month for the Heroku addon.
The second option is to host your Clojure web app on Amazon EC2. This can be done almost for free for the first year if your app is small enough. Check out AWS Free Usage Tier. Hosting web app on Amazon EC2 has its own upsides and downsides.
The third solution (probably, there are many other options out there) is the one, that I want to describe in this post.
Amazon has product in their AWS suite which reminds Heroku a lot.
It's called Beanstalk. According to Amazon docs:
New AWS customers who are eligible for the AWS free usage tier can deploy an application in Elastic Beanstalk for free.
Basically you will be able to deploy you app using following command:
lein beanstalk deploy prod Where 'prod' is the name of you environment that you need to specify creating Beanstalk app.
Creating Amazon Beanstalk application is easy. Just follow official docs. You can choose Tomcat 6 or Tomcat 7 as container (both 32 and 64 bit).
Usually I'm getting my SSL certificates from StartSSL.
They are providing Class 1 SSL certificates for 1 year for free.
You will get from them (after registration and applying for certificate) two files:
You shouldn't share these files.
I recommend to use Amazon Route 53 for managing DNS records. If you have a hosted zone on Amazon Route 53 for your domain name, then you need just to create new Record set of type A.
Select "Yes" for "Alias" field and you will be able to select Elastic Load balancer that works with your Beanstalk instance in the "Alias target" field.
After this is done you will be able to reach your web app using naked domain name (e.x. example.com instead of www.example.com).
There is a nice article in Amazon docs about how to add HTTPS support for your Beanstalk application.
You need to upload your SSL certificate using command
aws iam upload-server-certificate --server-certificate-name $NAME --certificate-body file://$FILE_NAME.crt --private-key file://$FILE_NAME.key You will get Amazon Resource name for your certificate similar to
After uploading SSL certificate you need to edit configuration for your Beanstalk app. In the "Load balancer" section specify:
In this post I tried to describe steps needed to have Clojure web app deployed to Amazon Beanstalk and make it available behind your own secure naked domain.
Described setup will cost almost nothing for the first year.
