Migration Recipes for Success

2. Cloud Stages of Adoption
Customer: AWS complements existing legacy systems and becomes an option for additional projects.
Customer: The enterprise changes view from “why cloud?” to “why
not cloud?”
Customer: The enterprise makes investments to sustain long-term IT operations in the cloud.
Project
Hybrid
Scaling
Customer: AWS is evaluated and vetted on a project-by-project basis to solve specific needs on a one-off basis.

14. Prioritization Process
1. Start by prioritizing applications already approved for cloud
2. Identify Operating Systems, Middleware, & Databases
• Often operating systems outside of Linux and Microsoft Windows such as
Unix are prioritized last due to major refactoring
• Review licensing of operating systems, middleware, and databases for
usage restrictions
3. Identify Available Application Validation Resources
• Prioritize applications based on the availability of resources with specific
domain knowledge

15. Example Portfolio Prioritization Matrix
Application BV CR R C Total
Corporate Intranet 1 5 1 1 8
Corporate Web Site 2 3 5 2 12
IoT Application 1 1 3 9 14
Data Warehouse Application 1 1 5 10 16
ERP Application 1 1 7 10 19
*Lowest numbers are prioritized first
**Create a portfolio prioritization matrix for each data center to assist prioritizing specific data center closures

16. • Use existing tools and AWS certified partners for
discovery process
Discovery Process Recipe
Ingredients
• Create portfolio priority matrix and have clear
dependency view
• Include infrastructure, application owners and
operational teams to gain full 360 app view
• Get quick wins with Dev, Test, Archiving etc

Application Transformation Patterns
The 6 R’s
• Customers will keep host / application in
their source environment
• Minimal analysis/validation of scope and
application affinity
• Dependency on integrating service
management
• Application and host decommission on
source
• No migration to target
• Application owner approvals needed
• Like for Like application migration to target cloud
• Minimal effort to make the application work on
the target cloud infrastructure (Minimal
application layout change)
• Storage migration will be needed (without
conversion)
• Up-Version of the OS and/or Database onto the
target cloud
• Some level of application changes
• Application reinstallation on the target
• Database to AWS RDS
• OS and/or Database porting
• Middleware and application change to cloud
service offering
• Data conversion; Database transition to
MySQL, Aurora, etc.
• Use SaaS-based offerings, application
architecture changes may require Porting
• Middleware, data modernization; application
consolidation / stacking

19. H
Destination – Landing Zone Options
• Identified applications require target VPC to move into
• Many considerations exist for this architecture:
• Account Structure
• Network Design
• Security Controls
• Access Control
• Automation Tools

20. A Landing Zone is:
- A baseline secure multi-account AWS environment configured based on
best practices
- A starting point for your application migration journey
- An environment that allows for iteration & extension over time
LZ Engagement is delivered by solutions architects or professional services
consultants to create a customized baseline of AWS accounts, networks,
security policies for a particular customer.

22. Pressure to move: Legacy Stack
• Fairly typical 3-tier architecture (PHP, JVM, MS SQL)
• 1.5 seconds / txn on 64 vCPU x 256 GB RAM
• Used-to-be scratch card lottery (7 years ago)
• > $ 1.5 Billion moved
• Custom event-sourcing inside single RDBMS table
• "Black" Christmas event
• Architectural review

23. Pressure to move: New Platform
• Business is very agile
• Design has to unlock feature and delivery scale
• ALSO: Traditional scale, 1 000 000 000 people
• Zero-downtime deployments
• Automation Friendly
• "I know! Let's use micro-services!"
• Tachyon
• Hashi-stack
• Identical environments (DEV, UAT, QA, Training, PROD)

24. Moving House
• Need "Improved" DR end
2016
• Practiced DR extensively
into many providers
• Got "comfortable enough"
• datomic has great reputation
on DynamoDB (nudges)
• OPS team chose a date
• Bring up entire stack
• Lots of testing, including load
• DNS, backups, failover
• Sunday morning to afternoon
• Kept old system for hot-
standby for 1 week
• COMMS!
• non-event

25. The dust never settles at Zoona
• Perf is phenomenal!
• 0.2 seconds / transaction
8 vCPU & 64 GB RAM
• Cost is significantly "lower"
• Launching new platform
soon
• VPCs, security groups
• default limits
• Hand-built SQL cluster
• High expertise in the
community
• AWS support very
knowledgable and engineers
are friendly
