    4. 4. Why are advanced load balancers relevant? <ul><li>Cloud-based applications depend even more heavily on load-balancing and optimization than traditional enterprise applications </li></ul><ul><li>Two customer examples running on clouds... </li></ul>© Zeus Technology 2008 Slide
    5. 5. YottaServe <ul><li>VirtualIron-based private cloud </li></ul><ul><li>Software L7+ Load Balancer </li></ul><ul><li>YottaServe take resource-intensive Web2.0 applications that don’t scale and ‘fix’ them. </li></ul>© Zeus Technology 2008 Slide
    6. 6. YottaServe © Zeus Technology 2008 Slide “ We were able to demonstrate that placing the load balancer in front of the application transformed the number of concurrent users from ten into thousands – with no application modifications needed.” Jeff Rhys-Jones, Founder, YottaServe Initial application tests show that response times rose sharply - up to over 100 seconds for a page request, as the number of users were ramped up to a test version of the website in the lab After application acceleration and traffic optimization, response times were less than 100 milliseconds - a complete performance transformation
    7. 7. Example – Gilt Groupe <ul><li>Flash-sales of designer and luxury goods; </li></ul><ul><li>>400 single-threaded RoR servers </li></ul><ul><li>Still was not enough during high traffic loads </li></ul>© Zeus Technology 2008 Slide
