Where to Begin? Application Portfolio Migration

Miha Kralj Principal Consultant, Amazon Web Services

•  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

Agenda

•  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

Determining Application Migration Options

Creating Application Migration Roadmap

•  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

Application Discovery and Collection Collecting Application

Portfolio Inventory

•  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)

AWS Cloud Adoption Framework

Strategy Perspective Identifying, analyzing and measuring the effectiveness of IT investments that generate the most optimal business value.

Process Perspective Managing programs and projects to be on time, on target and within budget, while keeping risks at acceptable levels.

People Perspective Selecting and training IT personnel with appropriate skills, defining and empowering delivery teams with accountabilities and service-level agreements.

Maturity Perspective Analyzing, defining and anticipating demand for and acceptance of envisioned IT capabilities and services. (Charting the right course)

Platform Perspective Defining and describing core architectural principles, standards and patterns that are required for optimal IT capabilities and services.

Operating Perspective Transitioning, operating and optimizing the hybrid IT environment, enabling efficient and automated IT Service Management.

Security Perspective Applying a comprehensive and rigorous method of describing a structure and behavior for an organisation’s security and compliance processes, systems and personnel.

Cloud Adoption Core Perspectives

•  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
