Roadmap

Scalarizer
- Complete rewrite of the lightweight Scalr agent that sits on your instances and collects data
- Makes it possible to add support for any server, on any platform (Ubuntu, Fedora support at first)
Scalr kernel
- Abstraction layer between EC2 and Scalr
- Makes it possible to add support for different infrastructure clouds
UI Improvements
- Faster user interface

Multi-image Roles
- Scale across multiple resource pools by mapping multiple images to a Role
- Set policy and priorities on each Role for each resource pool
Eucalyptus support (version 1.6 and above)
Scaling based on custom metric
- Define your own criteria for scaling, such as Daily Active Users, pageviews, or persistent connections to your application

Rackspace support
- Scale on Rackspace Cloud, with Fanatical Support™
Nimbula support
- Scale on Nimbula, the private cloud software built by the creators of EC2
Multiple regions for Eucalyptus
- Install Eucalyptus in all your datacenters, and have Scalr manage distributed applications across them
Chef-based Role builder
- Use the power of Chef to manage configuration on your instances
Major UI overhaul
- Servers, Roles and a few other objects can be managed without page reload
- Pretty URLs like /servers/view or /server/%SERVERID%/edit
- Almost all code responsible for UI on the server side is being rewritten
Safe shutdown
- Trigger a script prior to shutdown to authorize Scalr to terminate the server
HTTPS support for ELB
Ability to delete roles

Accounts and Environments
- Add team access to your Scalr account, with read/write permissions to your infrastructure
- Add multiple Environments to your Scalr account, to use dedicated keys for your development and production environments, or to manage your client
