We pushed a new release out this week, a few of you might have seen this already.

This is a rather important update, as it brings us closer to Scalr 2.0, which will extend Scalr to all Operating Systems and environments. You can find the complete list of features added below, and I’d like to highlight the Scheduler, the improved Monitoring system, as well as the shortcuts to your farms added to the top menu.

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!

Below is a complete changelog:

Spot instances is theoretically a great way to lower your web infrastructure costs: since the hourly cost of a Spot instance will likely not go above the rate of an On Demand instance, then if you set your Spot price above that, you will always keep your instances running. You’ll then be saving the difference between the current Spot price and that of a Reserved or  On Demand instance. Let us know if you try this and have any success with it.

To get started, from the menu: Tools -> Amazon Web Services -> Amazon EC2 -> Spot instances.

I hope everyone has a happy new year’s celebration!

Cheers,
Sebastian on behalf of all of Scalr

If response time is critical to you, you can now set this parameter and Scalr will add more nodes when response time on a URL increases above a threshold, or remove nodes when the response time decreases below another.

To access this algorithm, simply edit the Farm from the options menu, select the Role for which to change the scaling algorithm, click the scaling tab, and select ‘Enable scaling based on HTTP URL Response time’. Then add your parameters and url.

Cheers,
Sebastian
