GLOBAL CLOUD ACCELERATION
Slow performance effect on revenue
Revenue may be affected
•For an ecommerce site that is making $100,000 per day•Source: Aberdeen Group
A one second delay in page-load time across you site results in:
Load times matched to conversion rates
This Wal-Mart example, shows that milliseconds make a difference in conversions to sales and therefore revenue.
Search Engine Optimization also suffers
• Google uses website load speed as an organic ranking factor
• Crawling your site will also take longer and potentially Google will not index your site if it takes too long
GLOBAL CLOUD ACCELERATION
What can you do?
What can you do?
• Optimize website architecture, code, and content • Employ a Global CDN to cache non-dynamic content
closer to the end users • Use cloud acceleration to ensure that dynamic content
takes the most direct path, with the least amount of round trips to the end user
• Monitor site performance continuously § Gomez§ Workbench§ Google Analytics
OPTIMIZE CODE AND ARCHITECTURE
Combine JavaScriptCombine CSS style sheets
Combine Images using CSS Sprites
Reduce image size Minimize redirects
EMPLOY A GLOBAL CONTENT DELIVERY NETWORK
“Serving a global user audience from just one or two data center locations is difficult because of global Internet latency.”
“Global CDNs deliver top performance at the best cost efficiency”
The further from your origin, the worse the problem

Global CDN
• A CDN caches images, videos and content on points of presence closer to your end-users
• You do not have to build out datacenters, the CDN has built the infrastructure
• There is no Capex from your end• TIP: Ensure your CDN has points of
presence in all cities and countries you want to reach with your ecommerce site
