Existing Technology Investment
• Java stack, slightly left of center
– OSGi
– Spring
– MVC
– SOAP API set
• Why?
– Robust
– Fits in with Enterprise deployment and operational models, Java is
common
– Can run on an App server as well as plain OS
– Stable resource pool

Architecture - Model
• XML Model, based on formalized schema
• Generated Java Model (JAXB) used by JAX-RS for both XML and
JSON
– Keeps things consistent and allows us to formalize change
management for a published API

A digression - Build & Test
• Agile Development Process
• Continuous Build - Jenkins
• Automated Deploy and Test to the cloud
– ServiceMesh Agility provides the management infrastructure
– Jenkins invokes ServiceMesh Agility APIs to spin up VM images in
EC2
– Entire installation, configuration, integration process is scripted
– Test harnesses are executed
– Environment is torn down
– Test results posted back via Jenkins as build state
– Approx every hour

A digression - Agile Ops
• Multiple datacenters, SaaS and Managed Service, to meet
different customer requirements
• EC2 and Terremark
• Single point of management via ServiceMesh Agility
• Deployment is done from a tag in Jenkins and automated
• Once parallel environment is installed, it is switched over
manually
• Old environment is torn down after a day

What kept us awake
• Should we build an API? – yes, we could create a new UI and an
entire channel strategy without throwing away our existing
technology
• What API should we build? – a REST/JSON API to fully support
our UI, mobile devices, etc.
• How do we manage/secure/monitor this new channel?
• How do we get people to use the API? How do we promote it?
