Amazon Confidential Meeting increased capacity needs Distance learning “Since the beginning of the year, we’ve seen significant growth across Robinhood, including record trading activity and customer sign-ups. Thanks to the flexibility and power of the EC2 platform, we’ve been able to continuously expand our capacity to meet this demand. The AWS team has been invaluable in helping us tackle other challenges in scaling our services by advising us on potential demands, including helping us identify bottlenecks in how we integrate with RDS, the AWS hosted version of PostgreSQL.” — Adam Wolff, VP of Engineering at Robinhood

2002 - Bezos API Mandate 1. All teams will henceforth expose their data and functionality through service interfaces. 2. Teams must communicate with each other through these interfaces. 3. There will be no other form of inter-process communication allowed: no direct linking, no direct reads of another team’s data store, no shared-memory model, no back-doors whatsoever. The only communication allowed is via service interface calls over the network. 4. It doesn’t matter what technology they use. 5. All service interfaces, without exception, must be designed from the ground up to be externalizable. That is to say, the team must plan and design to be able to expose the interface to developers in the outside world. No exceptions.

Organizations are increasingly looking for options for employees to work securely from any location.

Customer case studies “At Amazon, we were able to burst scale our Amazon WorkSpaces environment - in 1.5 weeks - from a steady-state of 25k running instances to a maximum capacity of near 300k running instances across 8 regions; this ensures that every Amazon employee has a dedicated, remotely-accessible corporate computer.” Andrew Blackard, Manager, Client Engineering, Amazon “With Amazon WorkSpaces, we can provide new workers with a Windows desktop and the applications they need within hours instead of days. Because Amazon WorkSpaces is cost effective and requires no upfront payment, we have been able to save 30 percent of our desktop operations costs and 70 percent on capital expenditure.” Leon Backbier, IT Manager - Edemol Shine Nederland “In the past, opening a new office required a significant IT capex investment and took three to six months of planning. With Amazon WorkSpaces, we are able to save money on capex, and we can open a new location in days. Amazon Web Services has helped us accelerate the pace of growth for our business.” Elly Krommidas, Managing Director - CMC Property Services
