This document summarizes a presentation about architecting digital enterprises for transformation. It discusses how enterprises have evolved from mainframes to distributed systems to cloud servers using technologies like microservices. It also discusses how the enterprise architecture toolkit has grown richer with new languages, tools for dependencies, builds, testing, containers and monitoring. The presentation advocates for a modern architecture with a shared digital platform to increase efficiency and governance. It provides examples of deploying technologies like WSO2 for availability, scalability, continuous integration and delivery. Real-world client examples are also summarized.

3. The age of the consumer

4. Following the consumer

5. Today’s enterprise
vs 10 years ago
5
qEnterprises thrive to be
more adaptive
qThey understand that the
market need changes by
the day
qOrganizations have to
enable organic growth via
new channels
qNew challengers, but new
opportunities

6. Minimum Viable Product
Great ideas can be synchronous. One who
executes it first, wins the race

7. Mainframes
… with monoliths
Distributed systems
… with monoliths
… then SOA
Cloud servers
… with monoliths
… then SOA
… then micro-services
Waterfall Scrum XP (Agile*)
The sliding window effect of EA

8. The richer tool-belt for an enterprise architect
q More options for the enterprise architect
q Richer language tools (JVM based, browser / client based, device based etc)
q Dependency management & packaging tools
q Automated build and testing tools
q Software containerization and deployment tools / platforms
q Monitoring and analytics tools

9. The enterprise architecture has become complex
and simpler
q It is complex macro scale and simpler at the micro scale
q At a micro scale modules are more granular and loosely coupled
q At a macro scale it is complex in,
q Message passing (with eventing, caching, state management)
q Orchestration & mediation
q Security and claim management
q Governance and analytics

10. Digital transformation
q DT was the primary goal of the business since day one
q Today information technology can successfully augment the real-
world and real consumer needs
q A digitally transformed company is more closer to it’s customer

13. Building a Digital Platform
q A platform is a supportive structure that increase the efficiency of a
community
q A platform provides proper governance
q Establishes checks and balances

q Platform team
q Platform owner
q Platform architect
q Platform specialist
q Test automation
q DevOps
q Project team(s)
q Project manager
q Business architect
q Application architect
q Integration/implementation

19. Deployment Options

20. Deployment & Scalability
20
q Deployment for Availability
q Recommendation is a minimum
of 2 active nodes for a high
availability deployment
q Deployment for scalability
q TPS based scaling
q Elastic scaling via AWS/cloud
platforms like K8S/Docker

21. Dynamic & Static Scaling
21
Example A:
- Designed for possible Peak capacity Δ.
Example B:
- Designed for possible Average capacity 𝝺.Elastically scaled for higher capacity
demands by adding more nodes to the cluster.
