Applications - Challenges & How we addressed?
Problem
• Implement an end to end Data ingestion pipeline
leveraging the common Developer frameworks
without having to learn altogether new framework
Solution
• With Spring Boot and Data Flow, were able to
create the Data pipelines in a short time. Without
Spring, it would have elongated the Dev cycles.
• Poller & Streams Apps need to be HA to avoid data
processing backlogs
• Externalizing the configuration across many
applications and securing Credentials for Apps
backing Services
• Configured apps to auto-scale on Tanzu Platform
with 4 levels of HA
• Used Tanzu Platform:
• CredHub for Credential management
• Spring Cloud Config Service for
Configuration management
