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.

Where to Begin? Application Portfolio Migration

  1. 1. Where to Begin? Application Portfolio Migration Miha Kralj Principal Consultant, Amazon Web Services
  2. 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. 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 Collecting Application Portfolio Inventory Defining Segmentation and Prioritisation Criteria Determining Application Migration Options Creating Application Migration Roadmap
  4. 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 Collecting Application Portfolio Inventory
  5. 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) Defining Segmentation and Prioritisation Criteria
