7
Info Tech Meta Trends

• Growing EXTERNAL FORCES on IT
• Growing COMPLEXITY of IT
• Growing DEMAND for IT
• Growing DEPENDENCE on IT
• Growing THREATS via IT
• Growing IMMEDIACY of IT
• Growing NETWORK CONVERGENCE??

8
Growing EXTERNAL FORCES on IT

• Legislative/Regulatory
• Economic/Budgetary/Actuarial
• Society/Culture
• Greed
• Sociopaths, Terrorists
• Media
• Familiarity expectations, contempt?

9
Growing COMPLEXITY of IT

• Technical
• Political/Economic
• Legal/Regulatory

10
Growing DEMAND for IT

• More users
• More usage
• More features and services (pressures to do more
  stuff, e.g. CA)

11
Growing DEPENDENCE on IT

• Life-critical systems (e.g. Cerner/EMR)
• Network, Web, Email, Calendar oxygen

12
Growing THREATS via IT

• from spammers
• from immature adolescents
• from cyber-terrorists
• from complex/critical system bugs

13
Growing IMMEDIACY of IT

• Pervasive communications (e.g. embedded
  journalists instant war coverage w/GIS)
  
• Fast networks fast attacks (300K hosts in
  15min)
  
• Sensor networks omnipresent/omniscient rapid
  status reporting

14
Growing NETWORK CONVERGENCE?

• 1988 "Five anti-interoperable networks
• 2003 Common IP Bearer Service
• 2018 "One Network to Rule Them All" ??

15
Opportunities

• How might network-enabled immediacy and pervasive
  access to information help transform the way we
  do business?
  
• Operations/Project Management
• immediacy real-time status of systems, projects,
  priorities
  
• Disintermediation
• pervasive/direct client access to info/status,
  transactions

16
Tensions

• Management Expectations vs. Budgets
• Eternal triangle resources, requirements,
  deadlines
  
• Security Prevention vs. Detection
• Security vs. Networking
• Reliability vs. Complexity (MTBF)
• Reliability vs. Simplicity (SPOFs)
• Security, Reliability vs. Cost (e.g. isolation)
  cf. Converged net vs. separate servers

17
Network Convergence

• by technology (data, voice, video)
• by constituency (hospital, academic, admin)
• by bandwidth/interference risk (RD net)
• by economic model (premium services)

18
Motivations

• efficiency/cost
• innovation

19
Separation/Isolation at what level?

• Operational Goals
• by user (identity-based networking)
• by app (e.g. admin vs. research vs. control)
• by tech (voice, video, data)
• Technical Means
• 1 physical (fiber)
• 2 data link (VLAN)
• 2.5 network (MPLS)
• 3-4 network/transport (IPSEC)
• 5 session (SSL,SSH,Kerb)

20
Barriers to Net Convergence RATS(Regulation,
Accounting, Technology, Security)

• Concerns about interference, vulnerability
• BW contention/interference
• DOS interference
• Complexity interference (impact on reliability)
• Sensitive data vulnerability (exposure,
  modification)

21
Example of convergence concerns Backbone
Instability

• slammer
• multicast
• new complexity/new code (e.g. foundry arp and
  multicast problems)
  
• even redundant hardware! (e.g. BB switch fiber
  i/f problems)
  
• QoS? VoIP? IPv6?

22
Alternative Network Futures

• Separate nets for different apps
• Only port 80, 500 ever open
• Packet switching loses to lambda switching
• Totally open IPv6 net
• NAT everywhere
• Firewalls everywhere
• DENVLANs everywhere

23
Security vs. Network Utility Model

• NUM all ports are equal, ala electric utility
• Easier to diagnose/support
• Encourages innovation
• But end-point security is insufficient
• Defense in Depth
• Unfixable devices
• Thus Network Utility Model at risk from
  perimeter firewalls
  
• Claim NUM survival depends on providing local
  open/closed network choice
  
• Options P172, DENVLANs, ??(NB NUM also at
  risk from bw mgt)

24
CC (U-N-I) Priorities

• Projects
• Security,
• Reliability
• DRBR
• Middleware
• MIS/OIS Tools ??
• Organization
• Improved campus cooperation communication
• Improved intra-CC cooperation communication
• Improved project management skills

25
Your Current Challenges

• figuring out organizational layout, philosophy,
  and direction
  
• so much to do it's hard to determine the next
  high priority thing
  
• motivating myself when my morale is low
• project coordination
• unreasonable expectations
• dealing with external dependencies on getting
  things done
  
• facilitating progress on projects for improving
  core services
  
• figuring out how to be better prepared for
  disasters
  
• improving intragroup cooperation
• email inbox management
• time management
• trying to do more with less

26
Your Suggestions for NDC/CC

• more unity across departments
• a clear mandate encouragement to work together
  better
  
• collaboration on technologies of common interest
• technology focus groups with open membership
• client satisfaction surveys
• nice if we had the rep of providing "Service with
  a Smile
  
• areas that could be improved re cost-cutting and
  efficiency
  
• better cooperation, coordination, and
  communication between CC groups
  
• non-monetary compensation
• Hawaiian Shirt Fridays )
• expunge phrase "doing more with less from CC
  vocabulary

Dilbert on Working Smarter

• http//www.unitedmedia.com/comics/dilbert/archive/
  dilbert-20030504.htmlWally, can you teach me
  to work smarter, not harder?Walk briskly and
  pretend to be angry about what youre reading
  As a rule, people try to avoid anyone who has
  more problems than they do.

28
Management Philosophies

• Management by "Yes, Minister
• Management by FISH!
• Management by Deep Change
• NDC Core Values
• Seeking Serenity in Troubling Times

29
Management by "Yes, Ministera.k.a. Creative
Inertia

• New administration can't be too hasty.
• But is this the right way to achieve it?
• Not really the time...
• Have tried before but there are
  difficultiestechnical, administrative,
  legal...
  
• Will need extra staffing.
• Are you sure you can get approval?

30
Management by FISH

• Play
• Make their day
• Be present
• Choose your attitude

31
Management by Deep Change

• Choice Deep Change or Slow Death
• Changing others requires changing self
• "The tyranny of competence
• Transformational management

32
NDC Core Values

• Mutual Respect (Golden Rule)
• Dependability
• DWYSYWD
• Technical Competence
• Relationships Results over Process
• Design Principles
• Simplicity, Scalability, Small fault-zones
• HUI harmless, useful, indestructible

33
Seeking Serenity in Troubling Timesapplying the
harmless, useful, indestructible idea...

• to Systems
• Applications (GIGO or graceful recovery?)
• Systems (e.g. protected memory)
• Network (e.g. redundant paths)
• to Organizations
• Finding ways to be valuable no matter what
• Choosing to improve what we can
• to Ourselves
• Changing the internal/external dynamic
• Avoiding victim syndrome
• What helps you stay above water during storms?
  family? vivaldi? gardenias? purpose?

34
Success Metrics

• What should they be?
