AWS Summit 2014 Melbourne - Breakout 2
In the near future the majority of enterprise workloads will be running on public cloud platforms like AWS. In this session Fronde - an organisation with six years experience with AWS - will describe their approach to enterprise IT liberation; how to go about moving your complex workloads and strategies to overcome potential obstacles. We’ll demonstrate how we’ve moved traditional on-premise Citrix Virtual Desktop up to AWS to realise a Cloud Workspace for the future that delivers real business value.
Presenter: James Valentine, Chief Technology Officer, Fronde

7. CONFIDENTIAL | FRONDE 2014
GETTING STARTED
▪ Determine your desired “cloud personality”
▪ AWS Account(s) and IAM setup
▪ Base VPC network design
▪ Connectivity decisions
▪ VPN? Direct Connect? Public Internet?
▪ Migrate DNS to Route53
9. CONFIDENTIAL | FRONDE 2014
LIFT AND SHIFT
▪ The fastest, but ugliest, way to get a workload to AWS
▪ VM import; match networking; Rewire
▪ Iterate issue resolution quickly until it works
▪ Minimal changes to use AWS services
10. CONFIDENTIAL | FRONDE 2014
LIFT AND SHIFT
PROS AND CONS
CONS
▪ Potential for unknown
server configurations
▪ Unlikely to delivery full
AWS benefits
PROS
▪ Typically very fast
▪ Minimal changes to
current state - existing
operational processes
largely the same
11. CONFIDENTIAL | FRONDE 2014
CLEAN INSTALL, RE-ARCHITECTED
▪ Clean installs of application components
▪ Implement AWS best practices
• Configuration management
• Horizontal scaling
▪ Substitute AWS services for existing components where
possible
12. CONFIDENTIAL | FRONDE 2014
CLEAN INSTALL
PROS AND CONS
CONS
▪ Can take longer upfront
▪ Operational
restabilisation will need to
occur
PROS
▪ Deliver greater business
benefits
▪ Known configurations
▪ Future proofed
13. CONFIDENTIAL | FRONDE 2014
HYBRID APPROACH
▪ Replace obvious / straightforward components with AWS
services (e.g. RDS)
▪ Migrate the rest “as is”
▪ Build a backlog of unresolved issues and progressively
resolve them.
14. CONFIDENTIAL | FRONDE 2014
FRONDE MIGRATION CASE STUDY #1
▪ nakedbus.com - low cost travel operator.
▪ eCommerce stack; mobile backend; BI layer virtualised
within a single data-centre
▪ Selected Hybrid migration approach
▪ Transition savings paid for themselves within
▪ 6 months => fund improvements
15. CONFIDENTIAL | FRONDE 2014
BUILD AN OPERATIONAL FOUNDATION
▪ Implement monitoring - but not how you do it at present!
▪ Implement tagging / naming standards
▪ Determine your Billing & internal recharge needs
▪ Centralised logging & event management
16. CONFIDENTIAL | FRONDE 2014
GOTCHAS
Vendor support
Misaligned
Licensing Models
Shared storage
Multicast,
Broadcast etc.
19. CONFIDENTIAL | FRONDE 2014
CURRENT REALITIES
CHALLENGES
▪ Desktop management
complexity
▪ Stuck on legacy Operating
Systems
▪ Stuck in a cycle of refreshes
and upgrades
▪ Users demanding freedom
from
traditional IT
OPPORTUNITIES
▪ Anywhere, Anytime, Any
Device
▪ Browser and Mobile
delivered Apps
▪ BYOD
▪ Tablets and Chrome
Devices
On premise App/Desktop
Virtualisation too hard and too costly
LEGACY APPS
22. CONFIDENTIAL | FRONDE 2014
▪ Built through CloudFormation Configuration
▪ High Availability and Auto-scaling
▪ SSL termination with Elastic Load Balancing
▪ “Apps not Desktops”
MOVING CITRIX TO AWS
GOALS
23. CONFIDENTIAL | FRONDE 2014
THE CHALLENGES
▪ Driving total Windows configurations through
CloudFormation
▪ Fast Auto-scaling vs. Instance Bootstrapping
▪ Boomeranging Data Traffic
24. CONFIDENTIAL | FRONDE 2014
THE RESULT
▪ Rapid build out - no capital expense
▪ Time to market radically reduced
▪ Iterate entire stacks
▪ Able to prototype new services with low risk
▪ Unlocking Global potential
