Heroku is a cool PaaS (Platform as a Service) for deploying Ruby on Rails applications. It has even a free plan to help you get started (although, it has issue though – often the dyno becomes idle, so I won’t consider it for any real world projects/experiments) but the problem is – as you need more resources, it can easily get quite expensive and slow(if you don’t overthrow more dynos). By the way, if you’re aware of the Heroku’s Routing Secret (causing horrible response time for Rails applications) then it’s the time to look for alternative options.

What are some good alternatives to Heroku ?

Heroku is a Platform as a Service, so it lets you concentrate fully on the application development, by taking care of the server administration stuffs. So, If you want similar experience then you should try Redhat’s OpenShift or Cloud Foundry.

1. OpenShift

OpenShift is a free and open source PaaS for deploying web applications (supports all cool frameworks such as Ruby On Rails, Sinatra, Django, Node.js etc). They also provide a free plan to get you started – with 3 small gears for free! (gears are resource units, each with some limited amount of RAM (512 MB) and disk space (1GB)). For Rails , currently supported databases are MySQL, MongoDB and PostgreSQL.

Deploying Rails applications is also very easy (checkout an example rails app demo on github).

2. Cloud Foundry

Cloud Foundry is another PaaS platform for deploying web apps, it’s an open and scalable platform, from the VMware. It also supports a number of frameworks and tools.

checkout Cloud Foundry Project for more details and you can find a Core provider for Cloud Foundry.

There are lots of awesome Cloud Foundry providers including AppFog.

AppFog – it’s a PaaS built on Cloud Foundry, they also have a free plan with 2GB RAM, 50GB bandwidth etc to help you get started.

About AppFog

If you need more control over the things, then IaaS (Infrastructure as a Service) may be best suitable for you. AWS(Amazon Web Services) is the best option for that (Google has also offered similar services such as GCE(Google Compute Engine) but it’s very new and lacks a lot of features).

3. AWS

AWS offers complete set of services for building highly scalable web applications. It has S3 (scalable storage), EC2 (virtual servers on demand), Block Storage, Cloudfront (CDN), Cloudwatch, RDS (Relational Databases such as MySQL), DynamoDB (NoSQL store), Route 53, VPC, SES (Email Notifications), SNS (Push Notifications) and lot of other cool services to help you quickly build, deploy and scale.

Recently, Amazon has also announced a PaaS service, based on the top of their existing AWS services – Elastic Beanstalk, with the aim of simplifying deploying/managing applications.

4. VPS

Virtual Private Server (VPS) is a good option for small or medium sized predictable web applications. You can easily setup Capistrano for automated deployment. Once the things are setup, VPS management is not so hard as it seems, especially if you got a reliable and awesome VPS provider such as Linode or Digital Ocean (plan starts at $5/mo with 512 MB RAM, 20GB SSD and 2TB Bandwidth, not sure checkout the review of digital ocean)

If you’re not sure, where to begin then checkout this guide about deploying Rails applications to VPS

5. Cloud 66

Cloud 66 is an Application Stack Management as a Service, it’s a platform for provisioning, configuring, deploying and managing your web applications. it allow you to easily deploy (to any infrastructure such as VPS, AWS, Joyent Cloud, Rackspace and more) and scale, so you don’t have to worry about your configuring/monitoring your servers anymore. You also get a free plan to try (includes deploying to 1 server).
