  1. Richard Danielli, eSubnet Higher sales volumes through high network availability INTIX 2010

  2. About • Theatre tickets • Box office, call centre, online ticket sales • Daily traffic, first day rush sales • Challenges • Online complaints • Slow database • Connections dropping Ticket King eSubnet client Case study for higher volume ticket sales

  3. Ticket King eSubnet Services

  4. Availability of services • Users get what they want, when they want • Minimal impact by device down • Know your audience • More sales High availability networks

  5. A year has 483,840 minutes Measuring High Availability

  6. Technologies and equipment • Security • Implementation • Processes Achieving High Availability

  7. Internet

  8. Internet + connectivity

  9. Adding a router

  10. Adding a firewall &LAN

  11. Adding WEB and DB servers

  12. Adding user machines

  13. Typical network

  14. What you need for higher availability

  15. Identify where failure can happen

  16. Router fails

  17. Any piece fails

  18. Add redundancy (N+1)

  19. More WEB servers

  20. Add db servers

  21. Add firewalls

  22. Add DMZ (for security)

  23. Add a pair of load balancers

  24. Add a pair of edge routers

  25. Add connectivity access: ISPs in pairs

  26. High availability network

  27. Avoid single points of failure • N+1 redundancy • Stay away from consumer grade • Multiple ISPs are difficult and costly Equipment

  28. Technology Fault detection Automatic failover Server: RAID, diverse power LAN: HSRP, STP, port-channels WAN: Dynamic routing

  29. Technology • Server • RAID • RAID 0 – Striping (no safety) • RAID 1 – Mirroring • RAID 5 – Striping with parity • RAID 10 – Mirror with striping • Diverse Power • Separate UPS / Phases

  30. Technology • LAN: • HSRP • 3 IP addresses • 2 points of management • 1 Gateway • Spanning Tree • Root Bridge Selection • Convergence time • Port-channels • No wasted links • No convergence time

  31. Technology • WAN: • Dynamic routing • Link State • Hop Count

  32. Security • Clients entrust you • Security is a process • Network edge • In-house • BCP/DR

  33. Security • Security is a process • Not just quarterly testing • Everyone participates • Network edge • Firewalls Layers 3 & 7 • Filters • Bogon Routes

  34. Security • In-house • Anti-Virus • Back ups • BCP/DR • Remote location • Mimic Installation • What if scenarios

  35. Meetings • Maintenance windows • Documentation • Reviews • Testing Processes

  36. Processes • Meetings • Project updates • Summarize Environment • Maintenance windows • Scheduled • Minimize changes • Patching

  37. Processes • Documentation • Part of the routine • Easily accessed • Stored someplace else • Reviews • Log files • Traffic Stats • Testing • Pre and post testing

  38. Outsiders • Service Providers • Ask for references • Service Level Agreements • Consultants • Project based • Limited Engagement • Knowledge transfer mandatory

  39. The Hierarchy of Network Needs

  40. Assess & measure • Identify critical items, low-hanging fruit • Develop move-forward plan • Maximize availability TicketKing Our Process

  41. Stabilized the db • Doubled bandwidth • Add load balancing & more bandwidth • Improved WAN speeds • Improved LAN/WAN redundancy TicketKing results Action Items

  42. TicketKing Results

  43. Process improves awareness • Awareness improves stability • Stability improves availability • Availability leads to higher volume sales Higher volume sales

  44. Raising sales volume The Path to Success

  45. Standards Based • Best Practices • Documented testing “If you can't describe what you are doing as a process, you don't know what you're doing.” W. Edwards Deming Process

  46. Awareness • Know your customers – Inside & out • Know your environment • Know your traffic patterns “If you can’t measure it, you can’t manage it” Peter Druker

  47. Stability • Build in redundancies • Maintenance Windows • Consider a data centre • Security is required inside and out Just because you can, doesn’t mean you should.

  48. Availability • By being there you make the sale • Availability builds confidence and trust Quality begins on the inside... and then works its way out. Bob Moawad (Author)

  49. Questions for you to ask • Data Centre, inside or out • IT Staff, inside, outside or mixed • How many 9s can you afford to have • How many 9s can you not afford to have • What happens if…
