4 What is Sustainability to Akamai?

5 What is Sustainability to Akamai? Incorporate sustainability thinking into our business analyses to augment how we innovate around: Cost savings Risk and risk mitigation Revenue opportunities

6 What is Sustainability to Akamai? Energy & GHG by Activity Network (servers + colo facilities) Corporate Offices Employee Flights Employee Commuting Reduce network energy and carbon intensity by improving productivity of servers energy efficiency of servers and data centers Responsibly manage our electronic waste

7 Risk of Higher Electricity Prices Drives Efficiency Adoption of renewable energy portfolio standards by states A price on carbon Regulatory pressure on fossil fuel power plants Increased global demand for coal Refurbishment/build out of Smart Grid (near term increase) Trend away from nuclear power

8 Data is King What How What would can are Why we be the do compare the appropriate we impact do opportunities things if metrics we did this this to way?! that assess differently? will our afford the biggest progress? cost savings?

9 Metrics Intensity metrics: Energy per unit traffic (bandwidth) Carbon emissions per unit of traffic Proxy method for energy and carbon Measure the maximum power draw of each server config Snapshot the network for quantity of each server config by location Convert power to energy (assume 24/7 operations) and reduce ~15% Convert energy to carbon by location

10 Network Energy and Carbon Intensity (KWH or lbs CO2e/unit traffic) Normalized Traffic Intensity is decreasing % +4.5X Dec-08 Jul-09 Jan-10 Aug-10 Feb-11 Sep-11 -

11 Network Energy Consumption (MWH) CO2e Emissions (mtons).but absolute is still increasing 16,000 7,500 15,000 7,000 14,000 6,500 13,000 12,000 11,000 90% 83% 6,000 5,500 5,000 10,000 9,000 4,500 8,000 4,000 7,000 3,500 6,000 Dec-08 Jul-09 Jan-10 Aug-10 Feb-11 Sep-11 3,000

12 Filling Racks by Estimation 80% Max KW Rack unused X rack = # of servers Max Server Draw per rack (in lab) space = $$ Rack

13 How Are We Really Using Power? 100% Max Draw Relative to 80% Supplied KW 90% 80% 70% 60% 50% 40% 30% 20% 1x2 G7 SATA 1x2 X1 1x2 X1 16G 1x8 G4 SAS 1x8 G7 SSD 1x8 X1 SSD 2x8 G3 CacheH 2x8 G4 2x8 G4 8G SAS CacheH 2x8 G7 CacheH 2x8 X1 CacheH 3x18 G5 LCS NetApp filers + disks 10% 0%
