2. IaaS
• IaaS is a Public or Private environment which is billed on a utility
“what you use” model
• Defining characteristic of Cloud is self-service
• Lots of competing technologies eg.
KVM, LPARs, VMWare, Solaris Containers, EC2, Eucalyptus
• IaaS environments are essentially, for individual customers,
infinitely scalable
SAP/AWS
• SAP have been working in AWS since 2008
• Working on Project Titanium for 3 years
• Large supporter of Virtualisation technologies
• Use in Training, Project and Development systems
• Helping partners to build and develop services supporting Cloud

Facilitator
Consultant Cloud Admin
• Help IT administrate Infrastructure
and applications
• Design processes which meet
business compliance standards
• Build/Design flexible infrastructures
which are adaptable but controlled
• Migrate customers from outdated
platforms to next generation
platforms
• Help business develop and deploy
leading edge applications
• Curate and administrate flexible
landscape
• Additional to project/chargable
work, so primarily done outside
hours
• Team members need to be highly
adaptable, flexible, autonomous,
bought into the SoPs

Automation – Why do it
Insert "Title, Author, Date"
© 2012 Capgemini. All rights reserved. 7
• Systems administration is full of boring, repetitive tasks
• Evolve from thick manual run guides to smaller guides on
automated processes
•Create better results driven compliance processes and
records
• Quicker serial/parallel executions
• The execution of the tasks is more controlled
• There are lots of methods of automation, depending on the
layer you are working within
• OS – System schedulers
• Database – triggers or stored procedures
• Application level – scheduled batch or background jobs
• Captured input session tools
Ability to execute
consistent process
to serve multiple
compliance
frameworks with
different
documentation
requirements – eg,
ITIL, SOX, FDA,
etc..

DevOps

•DevOps is a methodology and philosophy which is used to
create and maintain flexible infrastructure and teams
• When used properly it can provide
• Consistent information,
• Auditable Processes,
•Automatic Measurement
C – Collaboration
A – Automation
M – Measurement
S – Sharing
We are uncovering better ways of
running systems by doing it and
helping others do it.
Through this work we have come to
value:
• Individuals and interactions over
processes over tools
• Working systems over
comprehensive documentation
• Customer and developer
collaboration over contract
negotiation
• Responding to change over
following a plan
That is, while there is value in the
items on the right, we value the items
on the left more.
Cloud depends upon close collaboration due to
rapid and shortened development cycles
• Flexibility and durations are important as the costs
are directly charged and very visible
• Projects tend use smaller teams
• Administrators often still have a day job managing
the Production infrastructure

Change management automation

Change management applies inside and outside of SAP
Purpose is to accurately record changes for a number of reasons
Infrastructure change management
• Information discovery tools
• Belarc
• SolarWinds
• Squirrel
• Configuration Management Databases
•Chef/Puppet
SAP change management
• Configuration discovery tools
• LiveCompare
• Solution Manager
• ABAP tools
• Transport management
•CTS+, Transport Express, RevTrac
Each automated system for applying change management usually also has a work flow
based approval system.

15. Exception monitoring is valuable because
• It identifies and alerts against things which are issues
• Can be narrow focus, for example only looking for critical issues
• Compliance is often based on exceptions/deviations, therefore exception
based reporting works well with compliance

Cloud Instance Management
Insert "Title, Author, Date"
© 2012 Capgemini. All rights reserved. 17
• Instances are the number 1 cost contributor to the normal AWS EC2 bill
• AMI’s are the biggest work load contributor to the EC 2 workload
• AMI ageing and patching
• Working with Dynamic resources
• Few AWS resources are static – this leads to interesting design/architectural choices
• Use of Elastic IP addresses vs DHCP&DynDNS
•Disk subsystem structuring – SAP vs World

Cloud Instance Management
Chris Kernaghan

• Instance control evolution has 3 main stages
• Always up
• Primarily each instance is up 24*7
• Start up and shutdown is manual
• Dumb Schedule
• Instances are brought up and down using EC2 API
• 3rd Party services
• Default down
• Chris Paine’s work with Google Apps provides a website with ability to start
instances
Instance type Typical Runtime Cost
Always up 720 hours/month (24hrs*30) $662/month
Dumb Schedule 450 hours/month (15hrs*30) $414/month
Default Down 120 hours/month (4hrs * 30) $110/month

Cloud Security Management
Insert "Title, Author, Date"
© 2012 Capgemini. All rights reserved. 20
Security Management is very important for 3 reasons
Flexibility is the mortal
enemy of security
Cheaper = Less security
because good security
costs money
Faster = leaves no time
to do security analysis
and implementation
Data Protection is
paramount, internally and
externally
Putting Production quality
data in the Cloud is
inherently risky
Cloud resources and
projects have high
degree of flux of Human
resources and reuse of
technical resources
Cost, utility billing means
a direct cost can be
placed on each instance
Security can provide
details of who is spending
what money

Cost Management and reporting
• Cost management is vitally important due to perception
• Move the perception to Value and ROI
• Define the KPIs early
• Use Cost calculators to show how much each instance costs
• Use automated reporting
