ABOUT PIERRE-ANTOINE GREGOIRE
Easing software architecture, software design and
improving related processes is and (as far as I can remember)
has always been my purpose.
Software Architecture and Agility are my current main centers of interest, as levers allowing me to simplify I.T.
not only for my own sake but also for my fellow coworkers, for projects stakeholders, and for operational teams
.
Continuous Integration and Delivery
DEVOXX FR 2014 - PARIS - 18 of APRIL, 2014
TODAY Software Challenges
Software projects are larger and complex
More and more component interoperability
Many teams and often remote teams
Tight schedules
Frequent needs and requirements changes
AGILE METHODOLOGY
AGILE IDEAL CYCLE
CONTINUOUS INTEGRATION
"Continuous Integration is the practice of integrating early and often, so as to avoid the pitfalls of
integration hell
".
CI == AGILE TOOLING
Standardize Build, Test and Deployment
Provide Continuous Builds, Test and Deployment
Ensures solid, reproducible and analyzable steps
Visible to all actors (Dev, QA, Product Owner)
GOAL
THE ULTIMATE GOAL IS TO REDUCE TIMELY REWORK AND THUS REDUCE COST AND TIME.
WHEN DONE WELL, CONTINUOUS INTEGRATION HAS BEEN SHOWN TO ACHIEVE THESE GOALS.
CONTINUOUS INTEGRATION STEPS
Fetch From SCM
Build Code
Run Unit Tests
Run Integration Tests
Deploy Artifacts
Run Acceptance Tests
Produce Reports
HUMAN WORKLOAD
Team members work on code
code
tests DESIGN
docs
Automated workload
POLL SCM AND CHECK OUT IF CHANGES
BUILD CODE
RUN UNIT & INTEGRATION TESTS
DEPLOY BINARY CONTENTS TO ARTIFACTS REPOSITORY
RUN ACCEPTANCE TEST
PRODUCE REPORTS
regarding tests
TESTS SHOULD COVER A WIDE SCOPE FROM DEV UP TO RUNTIME
UNIT TESTING
INTEGRATION TESTING
ACCEPTANCE TESTING
PERFORMANCES TESTING
UNIT TESTING
HERE WE TEST CODE
Ensures the code is doing what we intend it to do
Many extremely quick and small tests
UNIT TESTING ensure we make the software right
INTEGRATION TESTING
USED TO VALIDATE CONTRACTS BETWEEN PARTICIPANTS
SHOULD BE PORTABLE (NOT PLATFORM DEPENDANTS)
"External Components" SHOULD BE embeddedABLE or mocked
INTEGRATION TESTING ensure we make the right software
ACCEPTANCE TESTING
KEEP THEM SIMPLE
REAL TARGET COMPONENTS SHOULD BE USED
PREFER PRE-REQUISITE (DONT EMBED SQL DB ENGINES)
DATASETS IN USE SHOULD BE MODERATE
PREPARE FOR PRODUCTION - ENROLL YOUR OPS
PERFORMANCE TESTING
Fix quickly performance regressionS
Prepare for Capacity Planning
proTECT YOURSELF FROM IN-PROD DISCOVERY
CONTINUOUS DEPLOYMENT
CONTINUOUS DEPLOYMENT IS CONTINUOUS INTEGRATION ON STEROIDS
CONTINUOUS DEPLOYMENT FOR ?
YOUR DEVs
YOUR QAs
YOUR SUPPORT
YOUR SALES
AND OF COURSE YOUR CUSTOMERS
ANY MAGIC RECIPES ?
KEEP IT SIMPLE
THINK COMPONENT
ENROLL YOUR OPS !
A WORKING RECIPE - LEGO MODE
Assemble BINARY Artifacts TO CREATE RUNTIME COMPONENTS
EXAMPLE : A WEB APPLICATION
JAR + WAR + TOMCAT = runtime
VM + RUNTIME = SERVICE
ASSEMBLE THEM ALL
DEPLOY USABLE ARTIFACTS (RUNTIME)
READY TO USE BY UPSTREAM TEAMS LIKE QA-OPS (VM/RPM/DEB/MSI/NUGET)
IT SHOULD BE CONFIGURABLE FROM THE OUTSIDE (HARDCODING IS EVIL)
DELIVERY AND DEPLOYMENT
THERE IS NEEDS FOR CONTINUOUS DELIVERY
AND CONTINUOUS DEPLOYMENT
DELIVERY
ProvidE product to end user
User could then install or update it on his own systems
SOFTWARE VENDORS ARE IN "CONTINOUS' DELIVERY MODE
DEPLOYMENT
PROVIDE OPERATIONAL SOLUTION TO CUSTOMERS
CUSTOMERS COULD THEN DIRECTLY USE IT ON HIS OWN OR LEASED SYSTEMS
SERVICE PROVIDERS ARE IN CONTINUOUS DEPLOYMENT LAND (CLOUD)
CD : EXTERNAL APPROACH
Many good providers, Cloud Based
Cloud bees
*
, heroku
*
, openshift
*
BUT you MAY don't have choiceS and HAD do it IN-HOUSE
CD : In-HOUSE APPROACH
Materialize 3 chains
SOFTWARE FACTORY
QUALITY FACTORY
DELIVERY&DEPLOYMENT FACTORY
AND DONT FORGET SERIOUS MONITORING FOR ALL OF THEM
SOFTWARE FACTORY
FROM SCM TO ARTIFACTS
BUILDs
UNIT TESTS
INTEGRATION TESTS
CODE QUALITY REPORTS (SONAR)
DEPLOY BINARY ARTIFACTS
QUALITY FACTORY
FROM ARTIFACTS TO QA/RUNTIME REPORTS
CONSUME ARTIFACTS FROM SOFTWARE FACTORY
RUN ACCEPTANCE TESTS
RUN PERFORMANCE TESTS AND CAPACITY PLANNING
GENERATE REPORTS
DELIVERY & DEPLOYMENT FACTORY
FROM ARTIFACTS TO RUNTIME
BUILD NATIVE PACKAGES (RPM/DEB/MSI/NUGET)
BUILD IMAGES (VMDK, AMI, DVD ISO)
PROVIDE RUN INFRASTRUCTURE (INSITE)
INTERFACE TO RUN INFRASTRUCTURE (OFF-SITE/PUBLIC)
CATALOG & PROVISION RUNTIMES
INTERACTIONS BETWEEN FACTORIES
SOFTWARE FACTORY PRODUCES SOFTWARE MATERIALS
QUALITY FACTORY CONSUMES SOFTWARE MATERIALS
QUALITY FACTORY GIVES 'GO FOR DELIVERY' TO D&DF
D&DF PROVIDES QUALITY FACTORY RUN INFRASTRUCTURE

TO CONCLUDE
MANDATORY
FUN
SOCIAL
CI & CD ARE MANDATORY TODAY
PROVIDES AGILE TOOLING
ACCELERATE SOFTWARE PRODUCTION
SECURE SOFTWARE DELIVERY
CI & CD ARE FUN
COVERS A WIDE SCOPE FROM DEV UP TO OPS
LARGE SCALE OF TECHNOLOGIES
VERY ACTIVE ECOSYSTEMS AND COMMUNITIES
Always something new to learn and PUT IN PLACE
CI & CD ARE SOCIAL
WORKING WITH DEV, QA, OPS AND SALES TEAMS, CI & CD ACT AS FACILITATORS
