Roadmap

Align on business requirements; bring all stakeholders with you

Create your vision; incentivize team members to follow your lead

Define architectures, patterns, governance; measure, monitor, iterate

Publish guidance and guard rails for how to adopt cloud successfully

Provide centralized expertise; guide decentralized innovations

Define new operating models, policies, processes, economics; provide training

Start small and iterate, measure, manage, and update plan

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

Compelling Business Event

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

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

• Thousands of servers

• Aggressive migration timeline

• Large number of participants

• Combination of the above

What is a large-scale migration?

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…....

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…....

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

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

AWS migration playbook

Workload migration playbook phases

The workload migration playbook varies by customer, but typically

consists of ~9 phases and ~40 high level activities

Classify, re-platform or re-imagine, modernize application solutions

• Optimize Application Landscape to take advantage of the cloud economics.

• Remediate cloud anti-patterns through re-platforming and optimizing applications for cloud scaling and leasing capabilities

• Reduce TCO by 20-30% through application portfolio stratification and analysis

• Accelerate time to market with new applications and services with AWS application development methodology

• Develop new AWS-centric modern applications and platforms with CSC specialists; mobile, Internet of Things (IoT), and other user-experience driven applications for dynamic delivery of new function and service

CSC application modernization on AWS

I am interested in cloud but I don’t know what/how to execute

I need to understand what I have

I need to organize this information by application

Then I want to classify my applications to see what is easy/hard to move and why

Then I want to look at pricing & other factors around cloud providers to choose my destination

Then I want an easy way to set up that cloud environment

Then I want to migrate my application to that environment

Then I want to monitor and track the changes of that application in the cloud

Foundational Use Case Specific

Powered by

Cloud migration discovery methodology – strategic discovery

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.

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.

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.)

CSC and AWS at a glanceWorking together since 2013, CSC is an AWS Premier Consulting
