Application portfolio assessment is a technique used at the beginning of enterprise application migration process, helping migration team to gather, analyze and understand their app portfolio before deciding on priorities and sequences of application migration. Session will review the app assessment process, data collections, segmentation criteria and most common migration strategies and tools, helping attendees to better structure their application migration roadmaps

1. Where to Begin?
Application Portfolio Migration

2. Session Objectives
• Application Portfolio Assessment
– The decision flow, segmentation and prioritization
• Application Migration Factory
– Tools, processes and people required for mass migrations
• Cloud Transformation Framework
– Building the enterprise-wide IT transformation program

3. Application Portfolio Assessment
Step1:
Collecting
Application Portfolio
Inventory
Step2:
Defining
Segmentation and
Prioritization Criteria
Step 3:
Determining
Application
Migration Options
Step 4:
Creating Application
Migration Roadmap
• Conduct application
discovery workshop
• Interview application
owners
• Implement tool-based
discovery
• Profiling application
inventory
• Identifying complexity,
criticality and
preferences
• Clustering and
prioritizing
• Driven by prioritization,
skills and best
practices
• Use best patterns
• Capture inter-
dependencies
• From ‘lift and shift’ to
‘drop and shop’
• Expect complete IT
transformation
• Include IT process
changes and
organizational change
management
• Focus on new
Operations model

4. Application Discovery and Collection
• Semi-automated process with
automation rate improving with
experience
• Combination of AWS and partner
tooling with best practices and
custom questionnaires
• Requires light
participation/workshops with
business application owners
• Ranking is specific for each
customer/environment, but is based
on standard AWS approach
• Information collected:
– Name of the app, technical owner, business owner
– Number of systems: direct (exclusive), indirect
(dependent), non-prod (dev-test)
– Infrastructure desc (network, ports/protocols,
security, virtualizer, directory, OS)
– Information desc (database, data classification, data
exchange)
– App desc (app framework, middleware used, web
tier used, dev language)
• Automation tools:
– RISC Network – CloudScape
– ScienceLogic – CloudMapper
– ServiceNow – Service Watch
– Blue Stripe - FactFinder

5. Defining Segmentation and Prioritization Criteria
• Business criticality (frequency of use, size of user base, supported business
process)
– Deriving consequence factor of failure
• Technology complexity (dependencies, fragility, understandability of the app)
– Deriving probability of failure
• Sizing (how many systems, data volumes, storage size, other volumetric
requirements)
– Deriving effort of migration
• HA/DR/BCP (continuity plans, availability requirements, backup/restore
requirements)
– Deriving pre- and post-migration effort (cost of support and keeping the app current)

18. Conclusions and Recommendations
• Application migration is part of a larger picture
– Requires holistic assessment, planning and integration/transition
– Can be used to demonstrate the approach
• Disposition of each app should be value-driven
– Lift&Shift, Drop&Shop, Refactor&Rewrite
• Plan your own Cloud transformation program
– Every customer is unique, your mileage may vary
