Where to Begin? Application Portfolio Migration - Miha Kralj, Principal Consultant, AWS Application portfolio assessment is a technique used at the beginning of enterprise application migration process. It helps migration team to gather, analyse and understand their app portfolio before deciding on priorities and sequences of application migration. This session will present the app assessment process, the most common migration strategies and tools, and the placement of application portfolio migration in a complete IT Transformation process.

Portfolio Migration

2. Agenda
• Application Portfolio Assessment
• The decision flow, segmentation and prioritisation
• 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
• Conduct application
discovery workshop
• Interview application
owners
• Implement tool-based
discovery
• Profiling application
inventory
• Identifying complexity,
criticality and
preferences
• Clustering and
prioritizing
• Driven by
prioritisation, 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
organisational 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,
virtualiser, 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. Segmentation and Prioritisation 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)

17. 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
