Many large enterprises have begun using AWS to host development and test environments while also building greenfield applications in AWS. After realizing the benefits that AWS has to offer, many Enterprise look for ways to accelerate their migration to the cloud. In beginning this journey they are often faced with a number of challenges such as determining which applications should move, how they should move, and how can they be effectively managed in the cloud. Accenture, working with AWS Solution Architects, and AWS Professional Services have developed a framework, based on our experiences, to quickly, efficiently, and successfully move enterprise applications to AWS at scale. This session will review our approach, tools, and methods that can help Enterprises evolve their cloud transformation programs.

5. We see many enterprises moving to Cloud and AWS. To get started, we typically
see one of the below patterns:
Use Cloud for Test and Development
environments to improve development agility
Develop new applications on the cloud. Building
for the cloud, utilizing IaaS+, takes best
advantage of Cloud benefits
Use the cloud to improve current applications.
Cloud can be used for cheap storage, global
content delivery, or failover
Build new cloud applications that
integrate back to applications on-premises.
Examples include databases on premises
or thick clients
Move existing applications to Cloud.
Within Migrate, options include Lift
and Shift and refactoring the application
to use Cloud services
Move wholesale to Cloud.
(Has not been historical Enterprise use case, but
beginning to hear interest from a few of our clients.)
Examples include Netflix, Pinterest, etc.
Test/Dev
New Apps,
Greenfield
Augment
Integrate
Migrate
All-in

6. Within the last 6 months, we have seen significant client demand for migrations.
Clients are seeking to migrate hundreds to thousands of workloads to AWS. We
are hearing the following form our clients:
Challenges / Concerns
• Security
• Operational Impacts
• Lack of resources
• Lack of cloud experience
• Pressures of Shadow IT
• Older platforms
• Complexity of migrating systems and interfaces
Value Drivers / Benefits
• Agility
• Capital to Operation Expense
• Responsiveness to Business needs
• Cost Savings (in some scenarios)

The AWS Migration Framework assists Organizations to:
• Build an AWS Business Case, Strategy, TCO
• Rationalize the Application Portfolio
• Design a robust and scalable AWS architecture
• Define a migration approach and leverage automation tooling
• Integrate with and augment existing IT Processes
• Manage cloud environments through support models such as Accenture Cloud Platform

9. Unlocking the potential of the cloud requires a shared vision and roadmap for
business and IT.
Defining the cloud strategy
Our cloud IT strategy services help you
shape the direction of IT, taking advantage
of cloud computing, to maximize
shareholder and business value, while
controlling IT spend.
Priorities and business case for
cloud
Determine how cloud can be implemented
and integrated to deliver greater value to
your business:
• Align IT with business strategy to
determine how cloud computing can
support growth
• Prioritize cloud investments and align to
business imperatives to drive bottom-line
impact
Agree on the capabilities
for cloud
Confirm the new business and IT
capabilities, technologies and strategies
you’ll need to take advantage of new
business opportunities created by cloud.
Determine the best approach to realizing the
cloud-enabled future.
Pragmatic roadmap to the cloud
Generate alignment and buy-in to the pragmatic, actionable roadmap of change required to
take advantage of cloud computing. Sequence initiatives for the most efficient and effective
journey to cloud.

10. Building the TCO model is important step in the overall strategy and determining
what is best fit for cloud.
Understand current fully burdened cost per instance – both physical and virtual.
DON’T FORGET TO INCLUDE:
Physical Space Electricity / Fuel Blade Chassis Compute
Storage Hardware Cycles Backup Infrastructure Licensing
• Infrastructure labor such as virtualization management
and physical data center management
• Cost of unused capacity
• Costs of physical data center security
• Match your on-premises amortization
with cloud reserved capacity
• Include cloud provider tiered pricing
• Don’t forget the cost benefits of automation
• Cloud providers will typically provide
• Data center procurement

14. Design and architecture of the cloud environment is important to enable cloud
benefits such as agility and cost savings. Key components of cloud architecture
include:
Key areas of Focus:
Network Architectures
• Convergence of on-premise
networks to
cloud environments
• Using application and
cloud oriented protocols
• Homogenous network
constructs
• IP scheme and
addressing
Security Architectures
• Authentication/Federation
• Risk
• Audits
• Compliance
• Asset management
• IDS/IPS/HIDS
• logging
• MFA
• IAM
Governance
• Billing
• Cost management
• Asset management
• Inventory
• Controls
• Architecture
Standards
• SLA/SLO
• Procurement
Data Management
• RPO/RTO
• Retention policies
• Replication
• Storage optimization
• ILM
Monitoring
• Notifications/Alerting
• Application level

• Thresholds
• Service desk integration

15. Defining your architecture requires mapping of on-premise to AWS solutions:

16. • Language re-platforming: COBOL, PowerBuilder to Java, .Net
• Use of automated tooling such as Accenture’s Legacy2Cloud
based upon Blue Age software
Re-Platforming
• Major remediation required in order to be migrated, e.g., moving apps
using EJB containers to lightweight Java containers such as Tomcat
• Detailed assessment and thorough testing required to validate
• Combination of automated and manual remediation and deployment
• Minor code changes required to be migrated
• OS changes, version upgrade
• Limited configuration changes
• Automated and manual remediation; automated deployment
• No code changes or remediation required
• Scripted/ Automated
• Minimal or no impact to Business
• Minimal Testing required

18. Migration at Enterprise Scale
More than 50 delivery centers, across 5 continents, with 194,000
deeply skilled professionals. Accenture can scale to meet the
largest AWS migrations.

19. There are seven key components to an IT operating model. Each component is
impacted by cloud.

Key Challenges
SHADOW IT
Business demand continues to grow
and requires IT to respond quickly.
Slow response threatens to IT’s
ability to meet business needs.
GOVERNANCE
While Business demands increase,
IT needs to respond and add
governance controls, without
holding back the pace of innovation.
BILLING / CHARGEBACK
Understanding cloud provider billing
and showing detailed invoices with IT
services and be able to buy smart.
MANAGEMENT
IT is pressed to provide services on
a granular pricing basis. Existing IT
operations and tools do not often work
‘out-of-the-box’ with Cloud.

23. Key Challenges
