Benefit Type Infrastructure Efficiency Virtualization/ Cloud savings • Reduce/eliminate virtualization licenses for workloads to be containerized $$$ Hardware savings • Reduce number of hardware blades/servers/cloud instances $$$ Flexible platforms • Faster container startup times means instances can be turned off when not used, or dynamically scaled according to demand Predictability Container Benefits Dev. Ops Flexible application environments Efficiency Developer Productivity Architecture Alignment with modern architectures $ • Minimize environment and configuration defects in new environment setup by packaging all components and dependencies in containers $$ • Provision an arbitrary number of application environments easily, when needed, and destroy them when done �� • Minimize human effort / involvement with deploying code to new environments • Greatly reduce the amount of time needed for a developer to create a working application environment locally • Containers are a great runtime platforms for modern scalable and high performance application architectures, e. g. microservices $$$ � ���

Understanding how to design for, and with containers L 1 L 2 Business Continuity Operations Agility Information Security Adaptability and Flexibility Prepare for Failure Infrastructure Independence Fit for Purpose Data Integrity Leverage Dev. Ops practices for container image build and deployment Version container images in repository Use container clustering and/or other HA practices Leverage service discovery for inter/external service lookup Use standardized and bestpractice components Prefer container image digital-signing Monitor container infrastructure components Make sure that logs aren't retained only in containers Use external persistence data sources for container data Use standard protocols to interact with interfaces Reuse services offered by platform and extend components if necessary Limit container access Container as the build artifact Encourage reuse of container definitions Leverage dynamic routing capabilities Immutable infrastructure, deploy by replacing old containers with new ones Prefer lightweight infrastructure components Use private or secure hosted image registry Principles Decisions Data and process must be encapsulated Communications Use isolated networking between containers, regardless of their location

Central Internal Team Project-based migration Migration factory Migration conducted by an internal team, staffed by current IT resources Leverage existing project team group to orchestrate and execute migration effort Centralized team working in concert with project teams to coordinate and migrate projects to the new platform - Team has other priorities - Limited or non-existent container skills - Limited migration skills - Increased number of resources - Limited cross-team knowledge sharing - Lengthier migration - Inconsistent migrations + Fast, efficient deployment + Shared team provides economies of scale and knowledge sharing + Optimized resource model + Focused on migration delivery and managed to avoid cost overruns
