Higher sales volumes through high network availability

INTIX 2010


  • 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


Ticket King

eSubnet Services


  • Availability of services

  • Users get what they want, when they want

  • Minimal impact by device down

  • Know your audience

  • More sales

High availability networks


A year has 483,840 minutes

Measuring High Availability


  • Technologies and equipment

  • Security

  • Implementation

  • Processes

Achieving High Availability


Internet


Internet + connectivity


Adding a router


Adding a firewall &LAN


Adding WEB and DB servers


Adding user machines


Typical network


What you need for higher availability


Identify where failure can happen


Router fails


Any piece fails


Add redundancy (N+1)


More WEB servers


Add db servers


Add firewalls


Add DMZ (for security)


Add a pair of load balancers


Add a pair of edge routers


Add connectivity access: ISPs in pairs


High availability network


  • Avoid single points of failure

  • N+1 redundancy

  • Stay away from consumer grade

  • Multiple ISPs are difficult and costly

Equipment


Technology

Fault detection

Automatic failover

Server: RAID, diverse power

LAN: HSRP, STP, port-channels

WAN: Dynamic routing


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


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


Technology

  • WAN:

    • Dynamic routing

      • Link State

      • Hop Count


Security

  • Clients entrust you

  • Security is a process

  • Network edge

  • In-house

  • BCP/DR


Security

  • Security is a process

    • Not just quarterly testing

    • Everyone participates

  • Network edge

    • Firewalls Layers 3 & 7

    • Filters

    • Bogon Routes


Security

  • In-house

    • Anti-Virus

    • Back ups

  • BCP/DR

    • Remote location

    • Mimic Installation

    • What if scenarios


  • Meetings

  • Maintenance windows

  • Documentation

  • Reviews

  • Testing

Processes


Processes

  • Meetings

    • Project updates

    • Summarize Environment

  • Maintenance windows

    • Scheduled

    • Minimize changes

    • Patching


Processes

  • Documentation

    • Part of the routine

    • Easily accessed

    • Stored someplace else

  • Reviews

    • Log files

    • Traffic Stats

  • Testing

    • Pre and post testing


Outsiders

  • Service Providers

    • Ask for references

    • Service Level Agreements

  • Consultants

    • Project based

    • Limited Engagement

    • Knowledge transfer mandatory


The Hierarchy of Network Needs


  • Assess & measure

  • Identify critical items, low-hanging fruit

  • Develop move-forward plan

  • Maximize availability

TicketKing

Our Process


  • Stabilized the db

  • Doubled bandwidth

  • Add load balancing & more bandwidth

  • Improved WAN speeds

  • Improved LAN/WAN redundancy

TicketKing results

Action Items


TicketKing

Results


  • Process improves awareness

  • Awareness improves stability

  • Stability improves availability

  • Availability leads to higher volume sales

Higher volume sales


Raising sales volume

The Path to Success


  • 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


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


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.


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)


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…
