digital technology landscape

Digital Technology Landscape Paul Fremantle CTO and Co-Founder

The action or process of adapting one thing to fit with another, or suit specified conditions, esp. a new or changed environment

The only competitive organisations in the future will be those that create adaptive

digital experiences

How can you become more adaptive?

● Serverless ● Microservices

Cloud Economics Is Driving This Push

K8s Has Won The Cloud Orchestration War

The Intersection of Microservices and Serverless is Happening in Kubernetes ● Deploy code directly onto Kubernetes ● Let Kubernetes manage the SLA outcomes ● Protect against {Amazon, Azure, Google} lock-in

Kubernetes provides Cross-Cloud Decoupling

Different Flavours of Integration

Adaptive Enterprise

An Adaptive Enterprise is made up of decomposed units • Functional • Architectural • Organizational

● Already we are seeing proliferation of microservices ○ E.g. 200 microservice with a 10

developer team ○ No clear structure ○ No registry

● However, good observability ○ OpenTracing, Zipkin,

Jaeger

Microservices and Serverless Need Governance

Registry

Gateway

Observability

Microgateway

● A control point for microservices and serverless architectures

● Provides a well-defined interface to a subset of APIs, Events and Streams

● A policy enforcement point ● An observability touchpoint ● Governance for Cloud Native

An Adaptive Enterprise Needs Architectural Units of Composition

Units of Composition

26

The cell is the basic structural, functional, and

biological unit of all known living organisms

• A governance and architecture approach • Independently deployable, manageable, observable • Within the cell, any-to-any communication • External parties must communicate via

microgateway

Cells aka “Units of Enterprise Architecture”

• The only competitive enterprises will be adaptive • Adaptive enterprises must decouple into cells • Products, processes and services become

integrations of APIs, Events and Streams • Open source and open cross-cloud create unique

value in this business architecture
