Heroku is the leading platform as a service in the world and supports Ruby, Java, Python, Scala, Clojure, and Node.js. Deploying an app is simple and easy. No special alternative tools needed, just a plain git push. Deployment is instant, whether your app is big or small.
Rackspace Cloud offers four alternative hosting products: Cloud Servers for on-demand computing power; Cloud Sites for robust web hosting; Cloud Load Balancers for easy, on-demand load balancing and high availability; and Cloud Files for elastic online file storage and CDN.Rackspace Cloud hosting customers never need to worry about buying new hardware to meet increasing traffic demands or huge traffic spikes.
Face to face in the news:


2016 - Rackspace adds cloud optimization platform to its private cloud. Beware Heroku


Rackspace partnered with AppFormix to bring its cloud monitoring and performance optimization tools to its private OpenStack cloud. This will give Rackspace customers access to AppFormix’s real-time monitoring, analytics and optimization tools (and Rackspace’s engineers will also use these to manage cloud for their customers). For RackSpace, this is a somewhat unusual move. The company typically builds its own tools for managing the technical side of its cloud businesses (and it was the founding member of the OpenStack project, together with NASA).

2010 - Force.com 2 - already 5 PaaS platfroms. Rackspace is in panic


At the Dreamforce conference, Salesforce demonstrated one more time that now it's not so interested in CRM (it was mainly a subject for jokes) as in cloud platforms. Following the release of SaaS database Database.com, the company introduced another big Force.com feature - Heroku - the PaaS startup that Salesforce has recently acquired for $ 212 million. Heroku - is a cloud platform for developing and hosting Ruby-applications (Ruby - is a popular framework for developing Web apps, created by 37Signals). Heroku became one of the five PaaS-services included in the new version Force.com 2. And the new structure of the Force.com platform now looks like this:

Force.com 2
Force.com is backed by cloud DBMS Database.com. And developers, depending on their skills and goals, can select one of five options:

- AppForce - platform for rapid app development. It allows to build apps with 80% clicks and 20% code
- Siteforce - platform for creating and managing external websites. It also utilises mainly visual development tools
- VMForce - platform for building Java-based applications. Supports easy migration of existing packaged enterprise apps to the cloud
- Heroku - platform for building Ruby-applications
- ISVforce - platform for SaaS providers, where they can host and manage internet services, sell them at AppExchange marketplace

Recall also that Force.com provides tools for developing and hosting Flash/AIR apps and integration tools for Google Apps.
