"here is my source code
run it on the cloud for me
i do not care how"
However, someone must care…….namely the platform SRE team.

Microservices in an enterprise landscape
Issue: Amount of microservices, multi-cloud, redundant code, manual setup
Reality: In a complex environment we needed to:
• Unifying development
• Logging, monitoring, metrics, configuration, code structure
• Find a way to setup new microservices fast in our SDLC
• Repository, pipelines, monitoring, logging, etc.
• Apply changes in our SDLC fast to the existing services
5
Automation is key in a world of microservices

Automation requires APIs
To automate the setup of a new service in all SDLC components, the components
need to provide an API or other way to configure it
• REST and/or Web-service APIs
• Command line interfaces (CLI)
• The capability to define the configuration in a text format (YAML for example)
Provide a templating mechanism would be great

The perfect fit
Pivotal platform, Concourse and Spinnaker provide all we need for an automated setup
• Pivotal platform - platform as a service to manage containers and / or micro services
• cf CLI - cf push myApp.yml
• Manifest files with variable substitution support
• Concourse - build pipeline tool
• fly CLI - fly -t myTeam sp -p myPipeline.yml
• Pipelines defined in yaml format with variable substitution support
• Spinnaker - Continuous delivery platform
• spin CLI - spin pipeline save --file myApp.json
• Template inheritance

Generate vs. Inject
Generating pipelines, job descriptions or manifest files should be avoided.
Instead, focus on injecting dynamic values into standard pipeline/processes
• Jobs, pipelines, etc. will continuously be improved. You do not want to
regenerate them all the time
• Your infrastructure landscape might be complex
• Different environments (dev, qa, customer test, performance, prod, etc.)
• Multiple data centers (primary, disaster recovery)
• Multiple Pivotal platform foundations in each data center
• Multiple regions (US, Europe, Asia, etc.)
9
Always generate only, what is service specific

Handling permutations?
Define your configuration and then create files per permutation. An example:

Dev
Env
Qa
Prod
Foundation
Primary nonprod
DR prod
Primary prod
Region
US
Europe
ASIA
Template
MyApp
config for

Extending Spring Initializr
14
Spring Initializr supports generation of standardized Spring Boot applications out
of the box.
However, it can be also easily extended to create customized applications:
Demo will show how to:
• Add your company libraries
• Create your own files (e.g. service specific variable files like app.yml)
• Extend the UI to add your own values
