New source release – Scalr 2.5
Hey everyone,
We're pleased to announce a new stable release of Scalr available for download. Scalr's dependencies are still hard to install, but Scalr itself is easy.
You can request the source from http://scalr.net/features/open-source/
Why do we have a request form you ask? We want to be able to track downloads, as well as ask a few questions to find out what the community is doing with the source code. It also helps us find out if there are feature holes in our hosted offering. Finally, it'll help our sales offer software support.
Cheers,
Sebastian

Announcing Scalr 2.2!
"So, what's new in Scalr 2.2?" you ask?
Lots of things!
For one, you can now scale on the Rackspace Cloud, and benefit from their awesome Fanatical Support™!
You can now scale on the Rackspace Cloud
And if you're more into private clouds, you can now deploy Eucalyptus in each of your datacenters with a Region for each. Lets keep those machines working, baby!
Regions for Eucalyptus allows you to build applications that span multiple datacenters
Equally exciting is the all-new, Chef-based Role builder, that allows you to create roles from scratch, and assign 'Behaviors' to them (more on Behaviors in a later post).
Choose which Cloud infrastructure you want to deploy on...
Then choose your OS...
And choose the software you want. Voilà!
We've also built a new UI controller, that allows you to use different Scalr functions without a full page reload. This makes for a faster, more pleasant Scalr UI.
And then there's small things, like HTTPS support for ELB, and the ability to delete roles. And cookies that actually keep you logged in!
Oh, and did I mention a new Dashboard? You can vote on new widgets to add here.
The Dashboard now uses a widget system
2.1.1 released with many bugfixes
We released Scalr 2.1.1 today, which squashes many bugs. It 's available on code.google.com/p/scalr/ as a new download, and as a patch to 2.1.
Cheers,
The Scalr Team
Announcing Scalr 2.1!
- Eucalyptus support!
- You can now deploy Scalr on your Eucalyptus private cloud, or create Server Farms that cloudburst onto Amazon
- You can now deploy Scalr on your Eucalyptus private cloud, or create Server Farms that cloudburst onto Amazon
- Multi Cloud Farms
- Cloud and Region are now set per Farm Role, not per Farm, which allows you to create Farms that span EC2's East coast, West coast, Asia, and Europe datacenters.
- Service Configuration Manager
- Allows you to change configuration for the various services (Apache, MySQL) you use via the web UI, and have Scalr push the config to all servers in same group.
- Custom scaling metrics
- Gives you the ability to scale on your own, application-determined metrics, such as connected_users, or tps_reports_per_second
- Gives you the ability to scale on your own, application-determined metrics, such as connected_users, or tps_reports_per_second
- Multi-images roles
- A Role is now a collection of images, each of which is set to be used in a specific Cloud location. So if you deploy MySQL on us-east-1 and us-west-1, Scalr will use two images from the MySQL Role. When you create your own Roles, you'll be able to associate to it the images to use in different Regions.
- New farm builder interface
- Hopefully nicer for newbies
- Support for ELB sticky sessions
- Sticky sessions (which send same client to same host) were previously only available on the nginx software load balancer.
- API 2.1.0: added new methods for managing your Apache vhosts
- Ability to set VPC for farm role
- Various bugfixes and improvements
Enjoy!
Scalarizr source code now available
Hey everyone,
We posted the source code to the Scalarizr, the new data-reporting agent that enables communication between your servers and Scalr, on Google code.
Check it out if you know python, and want to contribute improvements!

The Scalr Team

2010 Resolution: keep Scalr on google code up to date!
Hi everyone, happy new year!
As part of our 2010 resolutions, we decided to keep in sync the source code on Scalr.net and that on Google Code. This is good news for everyone that deployed Scalr on their own servers, but also to everyone else as the power of open source lies in that other people can contribute to it. If somebody wants support for Eucalyptus, they can modify the source code to add capability for it, and send us a patch. We then merge it to the trunk, and you and everybody else then gets it. Patches should be sent to patches@scalr.com.
If you have suggestions for other resolutions, let us know!
