--availability-zones eu-west-1a
--min-size 4
--max-size 200
Auto-scaling
Automatic re-sizing of compute clusters based upon demand

28. Manually
Send an API call or use CLI to
launch/terminate instances – Only need
to specify capacity change (+/-)
By Schedule
Scale up/down based on date and timePreemptive manual
scaling of capacity
e.g. before a marketing event add 10 more
instances
Regular scaling up and
down of instances
e.g. scale from 0 to 2 for batch processing
every night or double capacity on Fridays
a) Scale up
b) Scale out
By Policy
Scale in response to changing conditions,
based on user configured real-time
monitoring and alerts
Auto-Rebalance
Instances are automatically
launched/terminated to ensure the
application is balanced across multiple
Azs
Rule 3: Handle requests at any scale
Dynamic scale based
upon custom metrics
e.g. SQS queue depth, Average CPU load,
ELB latency
Maintain capacity across
availability zones
e.g. Instance availability maintained in
event of AZ becoming unavailable

29. Rule 3: Handle requests at any scale

amount of capacity online in a short period of
time and allowed us to do so in an operationally
straightforward way.
AWS is now Shazam’s cloud provider of choice,”
Jason Titus,
CTO
DynamoDB:
over 500,000 writes per
second

Rule 6: Leverage unique cloud properties
a) Optimize costs with instance types

47. Unix/Linux instances start at
$0.02/hour
Pay as you go for compute power
Low cost and flexibility
Pay only for what you use, no up-front
commitments or long-term contracts
Use Cases:
Applications with short term, spiky, or
unpredictable workloads;
Application development or testing
On-demand instances
1- or 3-year terms
Pay low up-front fee, receive significant hourly
discount
Low Cost / Predictability
Helps ensure compute capacity is available
when needed
Use Cases:
Applications with steady state or predictable
usage
Applications that require reserved capacity,
including disaster recovery
Reserved instances
Bid on unused EC2 capacity
Spot Price based on supply/demand,
determined automatically
Cost / Large Scale, dynamic workload handling
Use Cases:
Applications with flexible start and end times
Applications only feasible at very low compute
prices
