Humana Digital Experience Center (DEC)

Humana DEC - History

•  The DEC is an acceleration center at Humana which

specializes in rapid application development of quality tested software using modern development practices.

•  Uses Pivotal Cloud Foundry to deliver highly scalable cloud native applications.

Humana – CF Enterprise Initiative

•  Quality as a Feature - Through our efforts to promote quality we expanded our Application Lifecycle Management platform, TFS, we noticed an increase in quality of delivery but still had challenges with provisioning, scaling and managing application runtimes.

•  History of Success - We looked to the success of the DEC and realized Cloud Foundry could be the platform of choice for application runtime.

•  Gather Support - A pitch was made to senior leadership to push forward with expansion of the existing PCF installation and make it generally available to the enterprise. The Cloud Foundry certification process was a big win to avoid vendor lock-in concerns.

•  Build and Learn - Working with Pivotal during a Dojo immersion session, we established goals and set forth building our future platform.

Considerations For Scaling CF in Enterprises

•  DR Topology

•  Capacity Planning

•  Charge Back model

•  Centralized Log Management & Application Monitoring

•  Pipeline for Automated Platform updates & Application CI/CD Integration

•  Changing IT Roles & Team Structure

scale up by adding more hosts at 30%

Measure Metrics Looking for (LETS): ●  Latency ●  Errors ●  Traffic ●  Saturation

Monitor to Understand Capacity

Humana - Charge Back & Pricing

Measures used to calculate Monthly Charge Back ●  App Instance Count ●  Service Instance Count ●  RAM ●  Disk

All Multiplied by Max Utilization % so you don’t over provision (ex: 70%)

How We Measure ●  Sample Usage Continually ●  Bill based on the MAX used that

month

Features of Model ●  Allows app owners to pay only for what they use. ●  Fits most contract models based on maximum utilization. ●  Allows for future expansion to smaller or larger billing windows for enterprises with

legacy models to modern models. (Daily, Monthly, Yearly, Continually)
