Application Portfolio Migration

Matt Tavis

Objectives

•  Application modernization and AWS o  The decision flow, segmentation, and prioritization

•  Building the App Migration Roadmap o  Tools, processes, and people required for mass migrations

•  App Migration and IT Transformation o  App migrations are usually just a workstream in a larger

transformation program

App Modernization is a Decades-old Problem

process

Common assumptions: •  The new environment can directly

map to the old environment •  Migration processes follow

traditional SDLC cycle •  Operations playbook will stay the

same •  People need minimal re-skilling

and restructuring •  Security, resiliency and availability

concepts are all the same in the old and the new environment

•  Network topology

•  Migrate •  Deploy •  Validate

•  Assessment & Profiling

•  Prioritization •  Data

Re-hosting (Lift & Shift) App Portfolio Optimization

Re-platforming (Lift & Reshape)

App Migration Methodology

•  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

Platform Integration

•  Infrastructure Services for Compute, Storage and Networking

•  Achieve Cost Reduction, quality increase and increased agility through lift&shift and afterwards optimization with cloud-native features (scaling, recovery, just-in-time infra, provisioning)

•  AWS provides Public Cloud computing platform, including managed DB, Storage, Networking & Automation, Logging, Scaling, DR, data integration, tooling

•  Set of best-of-breed, integrated components with clearly defined scope, SLAs and APIs

•  New developments (incl. Agile/DevOps) are Cloud-native (“infrastructure as code”)

•  Implementation guidance: highest aggregated service over lower individual components

•  AWS provides breadth of managed IT Stacks, including DWH, BigData, AppStreaming, Mobile, Deployment

Stack for Legacy Apps Integrated IT Stack

Stack for new dev & modernization

Application Migration – Compute

• Agent on source system cloning OS image • Snapshotting source image to target system • Typically one time migration

Host/OS Cloning

• Agent based data replication of source system at file system or boot level

• Continuously replicating into target volumes DR Replication

• Agentless, converts copies of vmdk into ovf format

•  Import into AWS through API VM Conversion

•  Agent on source monitor source app • Containerize application • Redeploy on provisioned target system

Takeaways

•  Application Migration requires a structured approach to assure consistent value realization

•  Do not over-analyze and over-design –  use optimization cycle to iterate

•  Application migration is just a piece of large-scale Cloud Adoption –  The Cloud Adoption Framework whitepaper:
