ABOUT US


What about You ?

How often do you release per year? How confident are you

when you release?

How long does it take you to deploy a code change in Production?

How fast can you fix a bug in Production?

How many different platforms do you manage?

How long does it take you to get user / customer feedback?


Business requirements

DEV QA/Test OPS/PROD Users

Focus of SCRUM

Focus of ITIL


The reality is often


Embrace the DEVOPS movement

Business requirements

DEV QA/Test OPS/PROD Users

FLOW

FEEDBACK

Make every Release a “non-event”


Culture: processes, people, mindset

Automation: virtualization, cloud, infra as code…

Lean: flow of work, small batches…

Measure: QA, user feedback, monitoring…

Share: information, knowledge, responsibilities, tools…

DEVOPS is…


Business user monitoring

Start your way!

EXAMPLE


Internal application with different developers involved from time to time

In successive time periods a developer may work on multiple customer projects with completely different contexts but with the same workstation

Time is money

Challenges


An evolutionary solutionA collaborative improvement

Developing on a workstation

Developing on VMs

Developing on provisioned VMs

Developing with containers


Virtual Machines


Containers on top (or not)

Data

Native

• VM created with Vagrantand Oracle VirtualBox• Auto provisionning bydocker machine• NoOps setup (script)

• Docker setup

• Tool chain setup

< 1 hour

< 15 mn

Work Station

• Vagrant• VirtualBox• Docker, Machine,Compose• Ansible• Text editor

Images built by devand opsDocker flow known bydev and ops


Developer environment harmonized, repeatable and destructible

• Managed as code in the common repository

Application environment treated as transient

• Updates, upgrades, patching does not impact server host

• Application stack not locked as “standard”

Workflow

• Autonomy of the developer

• Reduced setup time

• Throw it away when done

App


- Dev, Ops, Testers- In sync

- Share tool chain, code, practices and knowledge

- Feedback- From the CI platform

- From testers

- From interactions between parties

- Control- Source code versioning

- Infra code versioning

- Test code versioning

- Container images versioning

Benefits


- The use and management of application containers is not well-understood, “yet”!

- Docker isolation is not as robust as hypervisor isolation

- Orchestration is a challenge when containers are not handled as standard services
