In case you didn't know...

“The Financial Times (FT) is one of the world’s
leading business news and information organisations,
recognised internationally for its authority, integrity
and accuracy."




        … it is also one of the few newspapers making
        money with online subscription!
Our goal: Reduce Cycle Time



                    Up to 6 weeks for a release
Business
                                                  Customers
Idea




               We need to make this shorter!

              We want to release several time
                  a day without stress...
Problem: Long Feedback Loop

                                                     $$$

              ●No environment like PROD
              ●Manual Configuration

              ●Not enough environments




        Each deployment to PROD is an adventure...
Problem: Organizational Frictions


              Release Management




                    Network


                 Create Machine




    ●Dilution of Responsibility    Too Many
    ●Misalignment of Priority
                                   Gates!
Our Vision


                                 Release




                                 Network


                                 Create VM




                               Replace gates

Service Definition = Puppet Modules

   Versioned Module library


 Each service exists in its own Puppet environment
Everything you need to install a service is encapsulated in a
single versioned artifact excepted global configuration.
Puppet Master is part of a Service

                                             DNS2
 ●One Puppet Mater per Domain
 ●Contains “Mandatory” servers




No Sacred Cow!

… but we need a bootstrap
Bootstrap
             We start with vanilla VM including a Base RPM

    Base RPM
                      From vanilla VM to a running environment in a

   Versioned Module library



                What about Nodes and Config?
We don't use ENC
Service Definitions should contain everything we
need to deploy a service... so node definition
cannot be external!

                   ftaps123-lvpr-uk-p

             ENC                     Meaningful name in DNS


        ●class A                  access-app-01
        ●class B




            Node files defined at service level
Configuration with Hiera
Slight customization of the YAML backend to
use multiple configuration directories.


                               Facters:
                               Certname
                               Domain
                               Datacenter
                               Country
                               Environment (Dev, Test, Prod)


               Domain Level

               Service Level

               Global Config
Global Configuration Install
                              membership.test.cloud.ft.com


global-config-1.3.4
                      RPM      Puppet
                               Master




Global Config: Company Wide
Service Config: per service
Local Config: for override


                                         Domain
That's all Folks

●   Reducing bottlenecks:
    ●   Everything is a service
    ●   Team fully control service deployment
    ●   No sacred cow: Puppet Master is a service


●   Reducing Risk
    ●   Everything is versioned
    ●   Automatic deployment is the same everywhere
    ●   Responsibilities well defined

  • 15. We don't use ENC Service Definitions should contain everything we need to deploy a service... so node definition cannot be external! ftaps123-lvpr-uk-p ENC Meaningful name in DNS ●class A access-app-01 ●class B Node files defined at service level
  • 16. Configuration with Hiera Slight customization of the YAML backend to use multiple configuration directories. Facters: Certname Domain Datacenter Country Environment (Dev, Test, Prod) Domain Level Service Level Global Config
  • 17. Global Configuration Install membership.test.cloud.ft.com global-config-1.3.4 RPM Puppet Master Global Config: Company Wide Service Config: per service Local Config: for override Domain
  • 18. That's all Folks ● Reducing bottlenecks: ● Everything is a service ● Team fully control service deployment ● No sacred cow: Puppet Master is a service ● Reducing Risk ● Everything is versioned ● Automatic deployment is the same everywhere ● Responsibilities well defined
