Migrating workloads to AWS in an enterprise environment is not easy, but with the right approach, an enterprise-sized organization can migrate thousands of instances to AWS quickly and cost effectively. You can leave this session with a good understanding of the migration framework used to assess an enterprise application portfolio and how to move thousands of instances to AWS in a quick and repeatable fashion. In this session, we describe the components of Accenture's cloud migration framework, including tools and capabilities provided by Accenture, AWS, and third-party software solutions, and how enterprises can leverage these techniques to migrate efficiently and effectively. The migration framework covers: - Defining an overall cloud strategy - Assessing the business requirements, including application and data requirements - Creating the right AWS architecture and environment - Moving applications and data using automated migration tools- Services to manage the migrated environment

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 in the cloud. Building for the cloud, utilizing IaaS+, takes best advantage of cloud benefits
Use the cloud to improve current applications. Cloud services 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. Migrate options include lift and shift and refactoring the application to use cloud services
Move wholesale to the cloud.
(Has not been historical enterprise use case, but beginning to hear interest from a few of our clients.) Examples include Netflix, Pinterest, etc.

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 operational expense
•Responsiveness to business needs
•Cost savings (in some scenarios)

8. To support the massive internal and client demand to migrate existing workloads to AWS. Accenture and AWS partnered together to develop a repeatable and scalable method to migrate at scale.
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 the cloud
Determine how cloud services 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 the cloud
Confirm the new business and IT capabilities, technologies, and strategies you’ll need to take advantage of new business opportunities created by the 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 the cloud.

10. Building the TCO model is an important step in the overall strategy and determining what is the best fit for cloud computing.
Understand current fully burdened cost per instance —both physical and virtual.
DON’T FORGET TO INCLUDE:
Physical space
Electricity / fuel
Bladechassis
Compute
Storage
Hardwarecycles
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

Almost all points of IT operations are affected when moving to the cloud, although there are number of higher impact areas:

22. To meet our internal and client demand and challenges, we developed AccentureCloud Platform.
Cloud managementservices
Service and policy management
Self service
with governance
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 the cloud.

23. Key challenges
Agility
Rapid demand for new rapid technology development to advance the customer experience.
Governance
While business demands increase, IT needs to respond and run the solutions that are developed without holding back the pace of innovation.
