9. Many Failed Attempts
Successfully migrating to a public cloud
like Azure has many pitfalls often resulting in:
• Cost overruns
• Reduced functionality
• Missed deadlines
• Frustrated teams
Requires ongoing expert management
to deliver sustained improvements in:
• Performance
• Resiliency
• Compliance & Information Security (InfoSec)
• Monitoring & DDoS Protection + WAF
• Release Management and Automation

10. Cloud Migrations – Another Industrialization Wave
10
More Cloud Adoption -> More Standards, Less Confusion
More Standards -> More Commonly Used Tools
More Commonly Used Tools -> Improved Solution Delivery Techniques
Improved Solution Delivery Techniques -> Faster Speed to Market, Cost Savings
• Collaborative
• Transparent
• Reliable
• Predictable
• Cost Effective
• Scalable

11. Cloud Migrations – Common Reasons
11
We have re-factored a wide variety of standalone desktop applications and client/server
applications into “The Cloud”.
Some applications were written 20 years ago, were significant investments, they “work”, and
continue to provide business value.
However, with increasing frequency they are going “terminal”. Typical reasons:
• Programmer scarcity
• Earlier implementations of current languages in Architectures (e.g. Client/Server) that
cannot be effectively deployed without significant modification, e.g. C++, Java, C#
• User Experience awkward by today’s standards
• New Feature Requests that cannot be accommodated

12. 3 Options to Move Applications to the Cloud
Lift-and-Shift
12
• Duplicate what is already
existing.
• Usually very expensive in
terms of resource
consumption relative to the
other two options.

13. 3 Options to Move Applications to the Cloud
Lift-and-Shift
Re-Platforming
13
• Duplicate what is already
existing.
• Usually very expensive in
terms of resource
consumption relative to the
other two options.
• Least amount of changes to
move aka "lift-tinker-and-test-
and-shift".
• Can save significant dollars.
• Does not require a complete
re-architecture or
development of applications.

• Duplicate what is already

• Usually very expensive in

consumption relative to the

• Least amount of changes to
move aka "lift-tinker-and-test-
and-shift".
• Can save significant dollars.
• Does not require a complete
re-architecture or
development of applications.
• Modify the applications such
that they become cloud
native.
• Re-imagine how applications
are architected and
developed, typically using
cloud-native features.
• Optimal way to take
advantage of a public cloud
such as Azure.
• Can be cost-prohibitive from
an application development
point of view.

17. Determine Which Option Is Best for You
• Availability of development resources
• Use case market window
• Scalability concerns
• Ramp-up time

18. How to Take Full Advantage
of a Cloud Such as Azure?
18

19. Performance: Agility and Flexibility
Infrastructure User Experience
19
Scalability
• Deal with growth in users and data
• Use compute only when needed
Reliability & InfoSec
• Replication and recovery strategy
• Secure and protect the application & data
Flexibility
• Increase cadence of updates
• Evolve to meet new requirements
Response time and geo-distribution
• Serve pages closer to visitors
• Keep distributed content fresh
Health Monitoring
• Latency and response times
• Application behavior
• Down state

20. Resiliency
Business Continuity (BC) Disaster Recovery (DR)
20
• Alternate or remote personnel
• Alternate facilities and/or locations
• Alternate equipment
• Continuation or alteration of processes
• HR, development, accounting, etc.
• Contains DR procedures
• IT systems
 Assessment
 Repair
 Salvage or clean exit
• Backup strategy
• Business applications
• Corporate data

21. Compliance & InfoSec
Compliance InfoSec
21
• A demonstration of how your security
program maps to set of controls
defined by regulatory organization
• Typically a snapshot in time
• ”Check the box” to meet defined
requirements…nothing more
• Not your blueprint on how to do
security
• Programs that protect information and
assets from threats by controlling how
information and access is shared
• An ongoing set of programs meant for
iterative improvement year after year
• Requires continual understanding of
risks and threats to properly define
roadmap and strategy

22. Cost Savings
Direct Indirect
22
• Re-platforming into PaaS services cost
less to operate
• Pay for only what you consume in a
utility billing model
• Reduced on-premise footprint costs
• Better scalability due to re-factoring
requires fewer headcount resources
• Modern application monitoring
frameworks offer application usage
metrics

Feature Driven Development:
We focus on the following roles, activities, and
deliverables, seeking to understand how our clients
accomplish work in these areas.
Our goal is to establish a clear workflow of
handoffs, by role, that supports the continuous
delivery of ideation, requirements decomposition,
development, testing, and deployment of new
products / services to production.

29. Lessons learned and best practices
for planning a successful move to
a modern cloud?
30

30. When Is the Cloud Not a Good Fit
• Older Operating Systems (OS)
• Non-standard database technology
• Dated web development applications
• Environments which have hardware
dependencies
• Large data and file distribution where
egress (exit) is the majority of traffic
31

31. Compliance
32
Critical to consider the type of data
you are collecting/processing
• Personal information
• Health data
• Financial & card data
• Tax records
Data types are subject to different
security and compliance mandates
• Breaches can harm reputation
• Fines can be significant
• Increasingly country-specific

32. “Put the Cloud to Work”: A Continuous Cycle
Map existing environment to
corresponding Azure cloud
Move existing environment
to a public or private
Azure cloud
Transform applications to better take
advantage of Azure capabilities
Ongoing management &
maintenance to keep
running at its best
