Less is More: Utilizing
Ballerina to Architect a
Cloud Data Platform
Integrating disparate HR systems is a crucial challenge that enterprises face.
VHR's Cloud Data Platform, powered by Ballerina, provides a multi-tenant,
cloud-native solution to normalize data and deliver consolidated insights to
stakeholders.

Journey to an HR Cloud Data
Platform
• Background in architecture, development, and deployment of
Enterprise Resource Planning Systems
• ERP data sets and functionality should be fertile ground to enable
strategic planning with people data at the core
• Integration became the clear obstacle to achieving a consolidated
dataset from which to drive strategic decisions
• Integration is largely a solved problem now
• Industry, both application vendors and software vendors, have learned
from the past
• SMB and ERP products are not released without some approachable API
• The pivot is back to data acquisition, harmonization, and rendering

Ballerina's Role in the
CDP
1 Integration
Ballerina's native integration capabilities seamlessly connect diverse
HR systems, simplifying the data ingestion process.
2 Transformation
Ballerina's powerful data transformation features normalize the
disparate data models, preparing the data for analysis.
3 Orchestration
Amazon Web Service’s event-driven infrastructure, coupled with
Ballerina’s serverless deployment orchestrates the entire data
integration and processing pipeline.
Next Evolutionary Steps with
Ballerina
HR System Integration Maturity
Map
Using Ballerina’s Architecture View, we are rendering an image of
various HR systems in use within a client’s ecology, how connected
those are, and what gaps need work. This utilizes the Ballerina ChatGPT
connector to facilitate stakeholder interviews.
Amazon Bedrock
Connector
AWS Bedrock is used in conjunction with our Aurora Postgres database
to provide data for visualization in AWS QuickSight.
Retrieval Augmented Generation
Connector
With the vector database extension available in AWS Aurora Postgres,
Ballerina will be used to generate vectors from digitized content,
allowing Bedrock to perform predictive analysis for HR stakeholders.
WSO2's Partnership in the CDP's
Success
Fanatical
Support
From Discord to
StackOverflow,
assistance has
always been timely
and educational –
tremendous value
in just browsing
Discord.
Continuous
Education
Webinars and
Meetups and
Zooms occur on a
continual basis,
allowing expertise
to be passed on to
the community.
Top-down
Engagement
Not just shout-outs
to the Maryam’s
and Sameera’s who
constantly support
& educate, but also
the CEO jumping in
to facilitate
success.
Innovation
(nearly) On
Demand
Before developing
anything new,
connectors,
functionality, etc.
it might be found

Less Is More: Utilizing Ballerina to Architect a Cloud Data Platform

  • 1. Less is More: Utilizing Ballerina to Architect a Cloud Data Platform Integrating disparate HR systems is a crucial challenge that enterprises face. VHR's Cloud Data Platform, powered by Ballerina, provides a multi-tenant, cloud-native solution to normalize data and deliver consolidated insights to stakeholders. Bennett Reddin Founder/CTO VisualizeHR
  • 2. Journey to an HR Cloud Data Platform • Background in architecture, development, and deployment of Enterprise Resource Planning Systems • ERP data sets and functionality should be fertile ground to enable strategic planning with people data at the core • Integration became the clear obstacle to achieving a consolidated dataset from which to drive strategic decisions • Integration is largely a solved problem now • Industry, both application vendors and software vendors, have learned from the past • SMB and ERP products are not released without some approachable API • The pivot is back to data acquisition, harmonization, and rendering

  • 8. Ballerina's Role in the CDP 1 Integration Ballerina's native integration capabilities seamlessly connect diverse HR systems, simplifying the data ingestion process. 2 Transformation Ballerina's powerful data transformation features normalize the disparate data models, preparing the data for analysis. 3 Orchestration Amazon Web Service’s event-driven infrastructure, coupled with Ballerina’s serverless deployment orchestrates the entire data integration and processing pipeline.
  • 9. Next Evolutionary Steps with Ballerina HR System Integration Maturity Map Using Ballerina’s Architecture View, we are rendering an image of various HR systems in use within a client’s ecology, how connected those are, and what gaps need work. This utilizes the Ballerina ChatGPT connector to facilitate stakeholder interviews. Amazon Bedrock Connector AWS Bedrock is used in conjunction with our Aurora Postgres database to provide data for visualization in AWS QuickSight. Retrieval Augmented Generation Connector With the vector database extension available in AWS Aurora Postgres, Ballerina will be used to generate vectors from digitized content, allowing Bedrock to perform predictive analysis for HR stakeholders.
  • 10. WSO2's Partnership in the CDP's Success Fanatical Support From Discord to StackOverflow, assistance has always been timely and educational – tremendous value in just browsing Discord. Continuous Education Webinars and Meetups and Zooms occur on a continual basis, allowing expertise to be passed on to the community. Top-down Engagement Not just shout-outs to the Maryam’s and Sameera’s who constantly support & educate, but also the CEO jumping in to facilitate success. Innovation (nearly) On Demand Before developing anything new, connectors, functionality, etc. it might be found already completed on Ballerina Central
