Modernize
During this phase, you determine project goals and resource requirements, and you build out the implementation roadmap. The goal is to revitalize your applications by using a modernization program that creates a modern, agile application architecture.
Activities
-
Determine the milestones for converting your applications’ source code and data.
-
Complete the mapping of all operational areas to ensure that required standards and procedures for operating and administering the new target environment are addressed.
-
Implement an infrastructure solution that can address your reliability, accessibility, and growth requirements by using cloud-native approaches and best-of-breed languages and frameworks. The components of a modernized application have these characteristics:
-
Packaged as lightweight containers
-
Designed as loosely coupled microservices
-
Centered around APIs for interaction and collaboration
-
Architected with a clean separation of stateless and stateful services
-
Isolated from server and operating system dependencies
-
Deployed on self-service, elastic, cloud infrastructure
-
Managed through agile DevOps processes
-
Include automated capabilities
-
Provide defined, policy-driven resource allocation
-
Outcomes
-
Target state data model design
-
Organizational readiness built though training and tool improvements (change management and operational model)
-
Regular cadence established for change activities
-
Refined operating model and measurement of delivery effectiveness
-
Key business case metrics, which are tracked and reported for value delivered
-
Continuation of refinement and automation activities
-
A modernization roadmap that defines the strategy that is applied to each application and how it can scale
-
Preparation and implementation of modernization, including iterative testing deliveries that are synchronized with the new application roadmap
