Yuruware session for the AWS Summit Sydney, April 24, 2013. Building High Availability Applications in AWS. Reduce downtime and improve reliability with Disaster Recovery tool, Yuruware Bolt.

1. Automated System Migration, Backup,
Replication and Recovery as a Service
Yuru – ‘cloud’, Gamilaraay People NSW

2. Enterprise Disaster Recovery (DR) Under Pressure
• DR requirement growing due to
reputation risks, customer
expectations, regulations
• Infrastructure for DR is expensive, cost
is increasing
• Lack of confidence in initiating a
recovery (too long, too much
loss), uncertain integrity

3. Business Opportunity

4. Building HA Application in AWS
“Everything fails, All the time”
Werner Vogels, CTO Amazon.com
“If you want 5 9’s, you must run in multiple buildings”
James Hamilton, Distinguished Engineer Amazon
“Use exponential back-off algorithm...
and idempotent transactions... to achieve HA”
Simon Elisha, Principal Solution Architect, AWS ANZ

5. Some DR Reference Architectures from AWS

6. Migration and Replication across Global Regions

7. What is Unique?
• Business Continuity (BC) delivered as a pure play, self-service SaaS
–No setup, re-architecting, reconfiguring. No software to install.
–Pay per use pricing
–quick and simple delivery via SaaS platform and virtual onsite services
• BC delivering full warm standby, not just data backup
• BC in 6 clicks, ‘click and drop’ interface
• BC that can be tested
• BC that spans the globe
• 2 provisional patents

9. Yuruware Bolt Self-Service Interface

10. Tough Technical Problems
• Secure, fast and highly optimised inter-region volume transfer across the WAN
• Throughput ~5.0GB/h (AWS EBS Snapshot Copy 2.5 – 5.0GB/h)
• Parallelize transfer if necessary
• Incremental copy
– 10% of a volume contains new data  300% faster to sync the volume across regions
• API Management layer to shield jitter and variability
• Each API call: monitoring, automated retries with exponential backoff, cleanup upon a failure
• Task level: wrap API calls to give the illusion of “atomicity” – state-based clean up and retry
whole task
• Total workflow: Check point. Clean up and retry

11. Case study: HubWorks Migration
• No. 1 Australian Government accredited Child Care centre information management
service provider
• Need to on-shore sensitive children data
• Reduce migration cost while meeting legislation deadline
• Total end to end migration 0.5TB of system and data from US West to Sydney
completed in under 4 hours
• No application re-write, no business downtime

“This innovative migration technology enabled us to complete
the migration in hours, rather than days or weeks - error-free.
Our customers were not affected and it allowed us to comply
with our legislative requirements painlessly and cost
effectively.”
David Salajan, Director, HubWorks!
