› Communicating between microservice components
› State management & data bounding/residency
› Security between microservices
› Service discovery
› Resilience & transaction management
› No down-time upgrades

Forrester recommendations
• Digital is not about digital, it’s about agility
• Strategy is about acting & reacting, not about predicting the future
• Go beyond the solution architecture buzzwords
• Biz and tech design are the same conversation
• For every digital trend, APIs and microservices are underneath
• Evolve microservices based on pressure for speed of change
Prepare for an unknown future of change and disruption
Craft digital business building blocks
Place microservices and (external) APIs at the center
