1 Latency: The Achilles Heel of Cloud Computing David Lorti Product Marketing Manager Internap

2 What Cloud Computing Is Cloud computing, whether supporting file storage, SaaS, PaaS, or IaaS, or other variant, is a complex, multi-faceted technology solution incorporating numerous hardware, software, middleware, security and monitoring, and other capabilities to ensure application and information processing, reliability, performance, and security. Benefits to IT Organizations include: Reduces capital expenditures On-demand scalability/provisioning and pricing model Eliminates IT department infrastructure overhead Allows rapid implementation timelines that can align with strategic and tactical initiatives

3 The Cloud Computing Vision Cloud is Ubiquitous Applications will be consumed in every outlet. Far greater interoperability Uninterrupted workflows, aka Seamless Mobility We don t call it cloud anymore Open Source v Proprietary Cloud Environments

4 Top Perceived Cloud Computing Issues Top Concerns About Cloud Service Providers Data integration Compliance in the cloud Performance Contract negotiations Physical security Top Concerns About Cloud Service Providers SearchCIO.com May 6, 2010 Current cloud adopters are saying they want greater availability and performance.

5 What Cloud Computing Doesn t Do The cloud doesn t change end-user expectations for how your applications and websites operate, it only changes the physical and virtual location and architecture that they operate on. WARNING: Demanding End-user Requirements Still Apply One of the most important concerns for many Web businesses is how cloud adoption will impact their customers, the end-user.

6 Every Millisecond Counts A poor web experience results in lost revenue opportunity, a poorer customer perception of your company, and can boost your competitor s bottom line. 78% of site visitors have gone to a competitor s site due to poor performance during peak times. 88% are less likely to return to a site after a poor user experience 47% left with a less positive perception of the company Equation Research sanctioned by Gomez Application performance has become a critical competitive advantage, which has a direct impact on customer satisfaction, top line revenues and the bottom line. Shopzilla: A 5 second speedup in website performance resulted in 25% more pageviews, a 12% increase in revenue, and a 50% reduction in hardware. Amazon: Every 0.1 seconds in latency reduces sales by 1%. Google: Every 0.5 seconds in latency reduces traffic by 20%.

7 Every Millisecond Counts What s your application or website s TSL and how does it match up to pressures to perform? CL + NL = TSL Vision of website performance: Go from webpage to webpage as quickly as you can turn a page in a magazine. Attributed to Larry Paige, Co-Founder of Google Like us, our users place a lot of value in speed that's why we've decided to take site speed into account in our search rankings. Google Webmaster Center Blog, April, 2010 If we could come up with changes, enhancements or even alternatives to TCP/IP, or HTTP you know that might have a significant impact [to Internet performance] Steve Souders, Performance Evangelist, Google

8 Carrier Performance Why Network Performance is Relevant On average any one carrier represents the Best available path only 12% of the time. On average any one carrier represents the Worst available path 12% of the time. P(Better Option) = 88% 88% of the time any one carrier represents a less than optimal path across the Internet.

9 The Problem: Cloud is not all-encompassing Cloud- Based Application Cloud computing doesn t address overall data center architecture and redundancy, route optimization, or accelerated delivery of content. Border Router Switch Core Router C1 C2 Border Router Switch Core Router End User

11 SLAs Service Level Accountability Given the level of trust that customers must have to place applications and information in the cloud environment, cloud vendors must implement higher-level SLA and support models to address cloud performance/reliability and customer-related inquiries. Provider s uptime and performance service level and guarantee. Address latency and reliability from cloud to end-user Address slow performance and cloud downtime Proactive, generous credits for cloud performance Robust customer support mechanisms WARNING: Understanding your ROI is critical. A credit for downtime may not replace lost customers and revenue and typically does not address the impact of a slow network.

12 Connect End-Users to Cloud Consideration Cloud computing must meet all the same stringent demands for availability, performance, and reliability that exist for IT organizations today. But its consideration must also take into account latency and reliability beyond the cloud edge. Improved Availability Network availability is key to capturing customers and revenue. Availability is probably the most critical success metric for an online application. Improved Customer Capture Speed is important to the online user with studies showing that potential customers are more than willing to quickly abandon nonresponsive websites. Improved Efficiency For any transaction-based business, the ability to increase transaction and conversion rates brings you closer to being able to maximize the revenue potential of your business. Improved Customer Experience Customers who have poor experiences are more likely to leave a service (and more likely to talk about it) than any class of customer.
