What makes an application legacy?
• How fast can you make changes to the application and deliver it into
production?
• How much work is it to upgrade the application framework?

If we're creating 10x the number of apps,
we're creating 10x the technical debt

If you have to implement the same thing
in every application, it should be provided
by the platform as a service

is the valuable business logic

Platform Engineering
• Everything that sits around your applications is vital to supporting the health of
your applications
• Unfortunately, anything that is not business logic is going to make it harder to
upgrade your application later
• Platform engineering is the art of automating standards in an application
architecture by reducing redundancy across applications

Redundancy in code creates technical debt.
In microservices, multiply that debt by the
number of apps

Cloud Foundry Service Brokers
• The Cloud Foundry marketplace is similar to the idea of starter projects in Spring
Boot
• Services can be offered on Cloud Foundry and bound to your application
deployments
• These marketplace services can be seen as backing services for your
applications

Amazon S3 Service Broker
• The demo for this presentation is going to create an Amazon S3 service broker
• We’ll release the broker to PCF Dev
• Extend Spring Boot to automatically consume service instances from the
broker
• Deploy Spring Boot S3 browser that uses a starter project to connect to
Amazon S3

Cloud Controller
• The Cloud Controller is the contract that Cloud Foundry exposes over HTTP as a
REST API
• We can create service brokers that implement expectations from this contract to
allow CF and other broker applications to talk to each other

Spring Boot Service Broker Template
• The Spring team maintains an example project that provides the boiler plate for
creating custom service brokers using Spring Boot
• https://github.com/spring-cloud/spring-cloud-cloudfoundry-service-broker

Implementing the service contracts

• Service Instances
• Service Bindings

Service Instances
• Each method in the interface represents the implementation of a repository
pattern
• Controls the lifecycle of resources on AWS that provide exclusive access to a
S3 bucket
• The two resources that we will manage are:
• S3 buckets
• IAM users

Service Bindings
• The goal of the Amazon S3 Broker is to create S3 buckets that can be
automatically bound to an application
• Further, we want to make the service as easy to consume in a cloud native
environment using Spring Boot starter projects to auto-configure the connection
• The result of this is that a service binding will attach to a Cloud Foundry
deployment and inject the environment variables into the application’s container
• Our Spring Boot application will look for those environment variables at runtime
and automatically configure an S3 connection

Releasing the Service Broker
• There are multiple options for releasing service brokers
• Deploy as a CF app
• Release with BOSH
48
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
Why should we use BOSH to release a service broker
instead of deploying the application with Cloud Foundry?
49

It depends on the virtualized compute
resources you intend to manage with your
custom broker
50
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
When to use BOSH
• When you need to orchestrate resources with the IaaS provider that your CF
deployment uses
• Virtual machines
• Network resources
• BOSH provides a director API you can use to manage IaaS resources
• Portable with different IaaS providers that have a BOSH CPI
51
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
When not to use BOSH
• When you do not need to manage resources using the IaaS
• Example:
• Amazon S3
• Basically any AWS service that has an SDK
• Sometimes we just want to wrap another cloud service in a service broker, and
that is OK
52
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
Releasing with Cloud Foundry
• Let’s jump into code and release the S3 service broker as a CF deployment
53
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
Release steps
• Create MySQL database as a service binding for the S3 broker
• Build and push the S3 broker app
• Bind Amazon AWS credentials as environment variables
• Restage the S3 broker
• Create service broker using CF CLI
• Enable marketplace access to S3 broker
• Create new service instance named s3-service
54
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
Extending Spring Boot
• We can create a starter project that includes an Amazon S3 template for
consuming S3 service instances
• All we need to do is to include the Amazon S3 starter project as a dependency
55
Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a
Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/
Custom Spring Boot starter projects
• We need to create two project modules
• Auto-configuration project with the client libraries to consume a service
instance (Amazon S3 Template)
• Basic starter dependency project that includes the auto-configuration
project using Maven

  • 45. Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Service Bindings • The goal of the Amazon S3 Broker is to create S3 buckets that can be automatically bound to an application • Further, we want to make the service as easy to consume in a cloud native environment using Spring Boot starter projects to auto-configure the connection • The result of this is that a service binding will attach to a Cloud Foundry deployment and inject the environment variables into the application’s container • Our Spring Boot application will look for those environment variables at runtime and automatically configure an S3 connection 45

Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ Why should we use BOSH to release a service broker instead of deploying the application with Cloud Foundry? 49

Unless otherwise indicated, these slides are © 2013-2016 Pivotal Software, Inc. and licensed under a Creative Commons Attribution-NonCommercial license: http://creativecommons.org/licenses/by-nc/3.0/ When not to use BOSH • When you do not need to manage resources using the IaaS • Example: • Amazon S3 • Basically any AWS service that has an SDK • Sometimes we just want to wrap another cloud service in a service broker, and that is OK 52
