Backstage is a leader in highly addictive online games with their Pulltabs and Scratch & Win Applications. Facing scalability and stability issues Backstage enlisted my help to bring them to the next level in their IT infrastructure. I quickly resolved the performance and scalability challenges of their applications and rebuilt core infrastructure to ensure they have a platform to grow from - using 100% FOSS. Backstage faces unique challenges; accelerated growth of new applications is common and they need to be able to provide resources at a moments notice. Using cloud computing technologies and OpenSolaris they are now able to provision new application servers quickly and cost effectively.
