Patterns for building High Performance Applications
Reduce
Latency
Scalability
High
Availability
Application requirements
4

5.
Scalability
No Load Balancing vs Load Balanced
Stateful vs Stateless
Synchronous vs Asynchronous
5

6.
Reduce Latency
Simplify – Not too many
moving parts, simple
application tiering
SOA
ESB
Host closer to
Customer – choose
Cloud Vendor wisely
Bring data close to customer – Cache
6
(browser, edge, webserver, data cache)

7.
High Availability
Master - Master Replication
mode
Master-Slave
replications mode
Write
Read
Write Update
Read
Master - Slave
Master
Fail Over

• Product Integration
Scalability Strategy
• Application Design
• Choice of
Application Frameworks
Architecture • Standards
Enforcement
High • Build & Release

• Stateless s
• Reducing Latency Cloud
Attributes
• Bring data closer to end user
• Do not have too many moving parts
• Host your application close to users!
• High Availability
Metered
Shared
• Fail Over usage
• Redundancy
You can read all the books in the world about riding a
bicycle, but you will not be able to ride one until you
get on it and fall off a few times.
