SHIFT IN STRATEGY Data as a Strategic Asset

Data as A Strategic Asset

Data as A Strategic Asset •  Board aligned that the Blue System should have a broader, aggregated data

asset as a foundation to drive value and enable future competitiveness

•  The System has many of the key data assets to enable immediate Plan business needs and Plans prioritized potential uses of collected data

•  Focus on Consumer


WEB SERVICES Data as a Strategic Asset

What is Web Service Platform?

•  Web-Services Platform is an enabler to provide Access to the said Data in a real-time, secure, responsive and reliable manner

•  Different software systems often need to exchange Data with each other, and a Web-Service is a method of communication that allows two disparate software systems to exchange this Data over the network


Why is there a need for Web Services?

•  Once data is collected, cleansed and organized…

•  … a reliable and secure method is necessary to access this data

•  … and mask all the data storage and retrieval details

•  … and provide fast, real-time access to meaningful and actionable information

•  A Web-Service (using Application Programming Interface – API) is an industry standard to accomplish this


What types of Data is available via Web Services? •  Consumer Cost •  Patient Review of Providers •  Provider Data •  Provider Faceted Search •  Member out of Pocket •  Eligibility •  Claims Status •  Subscriber information •  And more …

Volume


So, what’s the problem?

Capacity: Unexpected exponential volume increase Performance: System Performance issues Response Time: Need for sub-second response for 100% of requests Increased Research Time: Excess time taken to research root cause Customer Satisfaction: User experience impacts Copyright © 2015 AppDynamics.

Where does come in?


Existing monitoring tools had limitations Need for a APM tool that will quickly point us to the problem Fairly new to using AppDynamics Still in the infancy stages of adoption Started with web services, expanding to Tier-1 Business Applications Working on a long-term strategy to integrate AppDynamics into SDLC and Operations

What we learned… couple of examples:

Application: Code inefficiencies

Example: Zip code search Database: Query

Example: Queries mining large data volumes for small inquiries


What we did…

Added Intelligence into the code Changed the way code returned results to users Significant query tuning Expanded the environment to highly clustered Separated web-service calls into smaller service methods Moved from Core Warehouse to DataMart model Copyright © 2015 AppDynamics.
