Read the original article at Autoscaling MySQL on Amazon EC2
Autoscaling your webserver tier is typically straightforward. Image your apache server with source code or without, then sync down files from S3 upon spinup. Roll that image into the autoscale configuration and you’re all set.
With the database tier though, things can be a bit tricky. The typical configuration we see is to have a single master database where your application writes. But scaling out or horizontally on Amazon EC2 should be as easy as adding more slaves, right? Why not automate that process?
Below we’ve set out to answer some of the[Read more...]
With the fast growth of virtualized data centers, and companies like Google, Amazon and Facebook, it's easy to forget how much is built on open-source components, aka commodity software. In a very real way open-source has enabled the huge explosion of commodity hardware, the fast growth of the internet itself, and now the further acceleration through cloud services, cloud infrastructure, and virtualization of data centers.
Your typical internet stack and application now stands on the shoulders of tens of thousands of open source developers and projects. Let's look at a few of them.
1. Operating System - Linux
The commodity hardware craze would never have happened without the help of an open-source operating system to run on it. Linux is an old story now, nonetheless everything else stands on it's shoulders.
2. Multi-purpose[Read more...]
1. Use Auto-scaling
Auto-scaling is a unique feature of cloud computing and Amazon's EC2 offering. Setup a load balancer and a couple of webservers for your application as you normally would. Design your webserver based on a template AMI that you'll reuse over and over. Then setup auto-scaling and set thresholds based on the traffic you forecast. When a threshold is passed, AWS will spinup a new instance of your webserver, and roll it into the load balancer pool[Read more...]

UPDATED - I had to update this post after a conversation with RightScale founder and CTO Thorsten von Eicken and for Sun’s Open Cloud announcement, which are both now included below.
There has been some substantial technology and news regarding open source software in cloud computing lately. More proof that open source is reaching into nearly all aspects of enterprise and broader IT, and also reinforcement of the idea that open source software will continue to have a pervasive and disruptive impact on the way organizations of all shapes and sizes do their computing and deal with their data.
First up is RightScale, which as detailed by 451 colleague and Principal Analyst William Fellows, is up and running across the pond on[Read more...]
