Scaling Applications for Large
Promotions and Events
What is a
Large Scale Event?
What is a Large Scale Event
An event where you need more capacity than normally
allocated for a period of time
Typically from minutes to days, but could be a couple of
weeks
Often associated with a sudden surge of users
Hard to architect and provision for at a reasonable cost
Consumers get angry when it all goes wrong!
What is a Large Scale Event?
For you, it could be as simple as needing twice as much
capacity for a short promotion
Everyone’s Large Scale Event is different, but the
underlying concepts are the same
What Problems do you Face?
Unknown infrastructure requirements
• Cost?
Short duration of the event
• Massive investment in infrastructure that is otherwise idle or underutilized
• Often tight deadlines to get the system live
Legacy system integration
Understanding system bahaviour, required metrics
Getting the right architecture
Finding the right talent
You Don’t Want This!
One question is
constant!
How do we scale,
especially the
database?
Let’s Look at Some
Customer Examples
Gumi Asia - Singaporean
Gaming Company
Sizing for Peak Loads
Promotions cause huge spikes in user activity
Auto-scaling works for the web and middle tier
RDS instances have to be sized for peak loads
Adopted our recommendations in a staged approach

Lessons Learned
Listen to AWS Business Development and Solution
Architects ;)
Gaming promotions much easier to handle
Unpredicted loads also easier to handle
Senior operations person moving to a new game
Customers get a much better gaming experience!
Singaporean Telco
Customer Success Stories
Telecommunications Company

Great Success!
Tested with 150,000 concurrent users
All phones gone within 2 minutes
No phones misallocated or unallocated
Management said the system was too fast!
Actual launch went smoothly
Lessons
AWS can provide infrastructure for applications to scale to
very high concurrent users
Managed services allow for quick deployment and changes
to infrastructure
Impossible for the customer to execute internally
Massive cost savings, even with huge over provisioning
“With our systems on AWS, we
can scale our resources more
than 130-fold in 30 minutes,
enabling us to support more
than 2,500 orders per second”
