The document outlines 10 best practices for accelerating cloud migration: (1) define migration principles based on business drivers, (2) gain executive support, (3) assess migration readiness, (4) reconsider "lift-and-shift" approaches and instead optimize for the cloud, (5) involve security early in the process, (6) make decisions quickly and focus on automation, (7) learn through iterative delivery while also providing training, (8) leverage innovators and early adopters, (9) consider operations during migration, and (10) be prepared to adjust the approach when scaling up. The best practices are meant to help organizations overcome risks, reduce costs, and deal with pressure when migrating to the cloud

It’s hard to drive real change when so much budget
just supports the status quo

Mature organisations are
often built upon a complex
digital tapestry that embodies
years of technical debt.
Addressing this issue allows IT
organisations to better serve
the needs of the business,
and enable digital
transformation

Benefits
Reduced storage costs 50%,
compute costs 20%, and sped
up provisioning by 10x (4
weeks to 2 days).
Migrated data center assets
for several divested business
units in 6 months.

down to 6, re-allocated >$100M
toward key business drivers.
Migrated 8 of 12 data
centers to AWS, improving
performance, reliability, and
cost.

(5) Be quick on decisions and persistent on
automation to move faster
Revolving door
decisions
Avoid
“snowflakes”
Start automating
early
Migration decision
making should be quick
to avoid delays. One of
risk mitigation measures
is to seek decisions,
that can be reverted.
Application and
infrastructure patterns
allow to define desired
design only once and
help to avoid
unnecessary
compromises.
Documentation can be
outdated, scripts and
templates are up-to-
date. Decisions can be
changed quickly.

(6) Get security input embedded from day one
• No connection to data center
• Bills and invoices go to this account
• Volume discounts
• Minimal resources if any
• Consolidated Billing view
• Hybrid connectivity
• DNS & Directory
• Deployment tools
• Scanning infrastructure
• Monitoring
• CloudTrail and security logs
• Security tools and audit

A “hands-on” team that acts as a

initiatives.
Advisory
A consultancy team and policy board,
giving advice and providing guidance
on best practice to teams, establishing

(10) Tweak your approach when scaling up
Promote and share
early
Team members
rotation
Onboarding and
documentation
Show and tell meetings
are good starting point
to be inclusive about
upcoming changes.
More in the journey,
you can start being
more prescriptive
Migration teams
structure can be built
around workloads and
then transformed to
cover different steps of
the migration, using
experienced resources
Even if you want to do it
only once, treat it as a
re-usable activity, that
will help you to focus on
the process and be
ready for upcoming
changes (people
