WHY ARCHITECTING FOR AGILITY?

AN AGILE ARCHITECTURE ENABLES TEAMS TO WORK IN PARALLEL WHILE REDUCING DISECONOMIES OF SCALE.

METHOD AND TOOLS ARE ESSENTIAL BUT NOT SUFFICIENT. “MONOLITHIC ARCHITECTURES” MUST BE ADDRESSED TO ACHIEVE PRODUCTIVITY AT SCALE.

• Organisation & Culture

• App Architecture

• App Platform

• Mainframe Digitisation


HOW WE GO ABOUT IMPLEMENTING AGILITY THROUGH DIGITAL DECOUPLINGMoving from One-Speed IT to Multi-Speed IT requires an evolution at the architecture, technologies, people and processes.

HOW WE MET THE CHALLENGES…

ENVIRONMENTSCloud environments

RedHat OpenShift• Infrastructure management• Container creation & deployment• Virtual environment management

(OCP projects)

DEVOPSRelease pipeline• Enable tooling• Configuration management• Deployment flow• Automate everything

DEVELOPER PROCESSESAccelerated start-up• Microservices factory

Enabling developers and testers• Coding standards and QA• Task management

Quality gates• Code analysis & review• Automated testing


…HOW ADOP MADE A MASSIVE DIFFERENCE

Development

Code Review

SCM Build

Binaries

Automated Release Notes

Pipeline

Dev/STSIT PROD

• Pipeline covers development, package, test and deploy

• Code review process integrated into the pipeline

• Code is analysed for best practices and vulnerabilities

• Deployment is orchestrated into multiple environments

• Automatic dynamic environment reconfiguration

• Automatically generated release notes

Static Code Analysis

Package/Artefact

ARCHITECT FOR WORKLOADS

YOU NEED A SANDBOX CLUSTER

IT’S NOT AN APPLICATION SERVER, DON’T MAKE IT ONE

INFRASTRUCTURE STILL EXISTS

CONFIGURATION AS CODE

LEARNINGS FROM MICROSERVICES ON OPENSHIFT


TO UPGRADE, OR NOT TO UPGRADE

LOWER ENVIRONMENTS ARE IMPORTANT

IMMUTABLE CONTAINERS WILL SAVE YOU


… AND THE OVERALL THOUGHTS WE WANT TO SHARE

OPENSHIFT• Automate as much

as possible

• Abstraction from developers

• Config is your new enemy

• Persistent storage may not be easy

MICROSERVICES• Logging is priority

• Architect for liveness and readiness checks

• Integration principles still matter

DEVOPS TOOLING• Build in the cloud,

don’t wait for Infra

• The more open, the more skills you have

• Don’t idolize environments

THE FLOOR IS OPEN TO QUESTIONS…
