Creating a comprehensive, accelerated cloud strategy for a complex or federated organization requires a disciplined approach—one that balances the need for centralized governance with the opportunity to innovate across all engineering segments within the enterprise. In this session, will follow the Walt Disney Company’s journey to create an initial cloud value hypothesis and cloud business case, and then develop a structured approach towards cloud migrations and a "cloud-first" operating model. Attendees learn more about the key implications, risks, and considerations of the company’s cloud transformation program; see examples of reference architectures and implementation guides; and understand the required activities that contributed to the success of the program. The patterns presented are broadly applicable to complex organizations with global aspirations to make the journey to the Cloud. Session sponsored by Accenture

Cloud Program Guiding Principles
CLOUD FIRST
Instill a “Cloud First” philosophy for new
application and functionality development
RAPID PROTOTYPING
Take advantage of cloud services to rapidly
prototype new capabilities
and quickly scale them to production
AVOID ADDITIONAL COST
Migrate based on ROI and eliminate
any unused infrastructure
MAXIMIZE CLOUD BENEFITS
Focus on refactoring to gain scalability
and elasticity
SECURITY AND COMPLIANCE
Ensure that the cloud meets the security and
compliance requirements for the systems
that migrate
RISK CONTROL
Use the cloud to improve the resiliency,
availability, and performance of the systems

Building Cloud-native Applications
From IaaS and CaaS to PaaS and FaaS
VMs
•Infrastructure resources
(CPU, network, disk) as
the unit of work
•Provides APIs and tooling
for automating the
provisioning
Apps as Containers
•Infrastructure and resource
scheduling is managed by the
container platform
•Teams package their workloads
as containers, and the platform
is responsible for the
application lifecycle
•Teams can run any framework,
stack, or technology as long as
it’s packaged as a container
Cloud-native Apps
•Teams provide source code;
the PaaS builds, packages, and
deploys the application
•The platform handles the
lifecycle of the entire
application
•Provides a ready-made set of
backing services such as
databases, caches, and load
balancers
Apps as Functions
•Code with a clear entry point
and exit point (a “function”) is
deployed to the platform
•The platform manages the
lifecycle of the function
•Horizontal scaling is
completely automatic, elastic,
and managed by the platform
Flexibility Application-centricity
