As you begin to move out of your data center and develop a cloud-first strategy, you'll need support for large-scale migrations to AWS. In this session, CSC shares details about the journey to AWS by some of our largest enterprise customers. We provide best practices for planning your large-scale migrations and focus on business processes in addition to technology. We show how CSC used this approach to migrate to AWS as part of our separation last year into two publicly traded companies: CSC and CSRA. In less than six months, CSC took our 56-year-old company and broke it into two companies, one of which was brand new and without any infrastructure or enterprise applications. We explain how we leveraged the AWS Partner ecosystem to achieve this incredible IT challenge. Session sponsored by CSC. AWS Competency Partner

5. What is the AWS Cloud Adoption Framework (CAF)?
The AWS Cloud Adoption Framework is a simple and agile process for achieving sustainable business
value with AWS Cloud services. This adaptive, four-phase framework is designed for small or large cloud
transformations. It organizes the planning cycle and aligns the cloud strategy to the business objectives.
Start realizing value as soon as 1-2 months

Theme 1: “Have to Go”
- Rapid Data Center move or Decommissioning
- Depreciation of Capital
- End of Services Terms or Leases
- Clear ROI
Theme 2: “Need to Go”
- Less defined Business Case
- Less defined ROI
- Strategic Imperative
- Industry Trend
- Fear, Uncertainty, Doubt, and Resistance

8. Business needs are a major factor in defining migration
timelines and treatments
• Short (<3 months)
• Mid Range (3 – 12 months)
• Longer Term (1 – 3 years)
Note: Timelines can dictate treatments
Timelines

9. • Thousands of servers
• Aggressive migration timeline
• Large number of participants
• Combination of the above
What is a large-scale migration?

10. Application migration challenges
 Lack of accurate discovery tools and processes
 Lack of application contexts / information
 Limited CMDB or similar data sources
 Inaccurate on-premises costs
 Lack of detail and scope with respect to operating
model, governance, risk, compliance, security,
software licensing, etc.
 Potential operational practice maturity gaps
 Increased cost
 Longer time to value
 Inaction
Large migrations greatly amplify these challenges…....

11. Additional large migration challenges
 Efficient coordination and communications across a large team made up of
business, application, development, operations, and partner participants
 Discovering, transforming, and deploying complex sets of workload
components
 Demand for automated management of AWS infrastructure and applications
 Insufficient WAN bandwidth to support ongoing operations + parallel server
and data migrations
Large migrations face these additional challenges…....

12. Small to medium migration
Small to medium migrations have the following characteristics…....
Area Characteristic
Program & Project Management • Can get by with PMs managing activities with MS Project & Spreadsheets
• Can successfully leverage email and status calls to collect verbal updates, and
report on status
Infrastructure Provisioning &
Workload Migration
• Can get by with manual AWS infrastructure provisioning and workload migration
Team Size • Small to medium IT team with possibly some business stakeholders
Team Skills • Combination of IT & Business staff that manage and execute the migration. May
use contractors/partners to assist
Level of project scope & visibility • Smaller IT Project or major business initiative in a smaller company

13. Large migration
Large migrations have the following characteristics…....
Area Characteristic
Program & Project Management • Requires automated workflow and tracking for technical as well as program-level
visibility
Infrastructure Provisioning &
Workload Migration
• Requires automation of AWS infrastructure provisioning and workload migration
Team Size • 10s to 100s of staff performing coordinated/sequenced activities
Team Skills • Combination of IT & Business staff that have the context and AWS and/or Partner
staff that have the specific SME skills to drive down risk & optimize every aspect
of the migration
Level of project scope & visibility • Typically Tier 1 Business initiatives tied to strategic business goals/outcomes

14. AWS migration playbook

15. Workload migration playbook phases
The workload migration playbook varies by customer, but typically
consists of ~9 phases and ~40 high level activities

16. The 6 Rs of enterprise cloud migrations

• Replatform
• Repurchase
• Refactor
• Retire

24. Current Method of Assessment and Analysis
The process of analysis is
manual, time consuming
and provides little benefit to
the organizations they are
servicing
Most organizations that we
speak to are going through
a manual process of
conducting interviews with
their team and collecting
data manually
This process can take
months to years in some
cases, which means that
decisions are delayed by
months, potentially years
Our analytics deliver a great
starting point by automatically
collecting data in as little as
two - four weeks. It
drastically improves the
overall process.
Interviews, Manual Assessment
Decisions Are Delayed

publicly traded, pure play leaders: one to serve commercial and government clients and one to serve public sector clients in
the U.S.

Migrate to AWS GovCloud
Initiate an application migration to AWS GovCloud, via
cloning, cloning & import/export, rebuilding, or rebuilding

38. Success stories
• Hybrid environment (Compute, Network, Storage) on Physical Premises,
Dedicated Private Cloud, Government Community Cloud, SaaS Provider, all
seamless to the end user…. and it works!
• Use of AWS rapidly increased the time to value for our cloud-based IaaS
(compute, network and storage). Able to execute plan in hours/days vs.
weeks/months it would have taken using alternative IaaS with same requirements
• Agile methodology delivered value early, identified issues and mitigated them
rapidly.
• CSC used its own processes and methods to take on this aggressive application
migration effort—and they worked. Lessons will improve these migration offerings
passing on value to our customers.
• DR recovery point time reduced from days to minutes with some of these
applications. Architected for resiliency to failures.

39. Lessons learned
• No magic bullet for an enterprise migration.
• Plan for bandwidth. Biggest bottleneck in an automated migration/cloning to cloud
is bandwidth. Plan ahead, expect delays for bandwidth restrictions/issues.
• Do not disregard the importance of planning, especially the target environment
planning. Much harder to move migrated resources due to poor VPC/Target network
planning.
• Automation can not migrate everything, expect some traditional migration
methods to be required.
• No Re-IP’ing is a great goal, but not entirely possible in a large-scale migration.
• Most importantly… utilize your partner expertise, heed their advice (AWS,
Racemi, SaaS Partners, etc.)
