Active Omni Architecture

Technology Stack

• Java - Primary Programing language 
• SpringBoot and SpringCloud - Cloud Support
• Gradle - Build Tool
• Docker - Containerization
• Jenkins - Continuous Integration
• AWS - Cloud Formation
• GCP - Rubik (python/shell based)
• MySql - Database 

Technology Stack - Others

• Go
• Rundeck
• NodeJS
• and many more

Deployment

• Supports both AWS and Kubernetes
• Fully automated installations and upgrades. We mean it.  
• Components dont depend on Cloud vendor. Interaction abstracted with frameworks.

Deployment - AWS

• AWS  - Cloud Formation for infra setup
• AWS - ECS for container orchestration 
• Autoscaling partly using aws and partly using Hscaler

Deployment - GCP

• Takes advantage of Kubernetes 
• Rubik - wrapper around kubectl which takes are of orchestration 
• HScaler monitors infra and submits requests to kubectl to scaleup / scaledown
• Default choice of deployment going forward.
• Plans to move all production AWS customers to GCP / Kubernetes

Role of Frameworks

• Invested on framework to have consistency and avoid redundant code
• Entity FW - wrapper around ORM
• Batch - support for batch/scheduled executions
• Rules  - Supports conditions and actions
• AWPF - Async processing.
• and many more

Role of Frameworks - Entity FW

• Consistent and easy way to create entities and access them.
• XML based metadata
• Generates lots and lots of code
  • ORM mapping.
  • Service layer
  • Document Layer
  • Controller Layer
  • Swagger Docs
  • Security
  • Context

Role of Frameworks - Entity FW

• Multi tenancy 
• Extensible
• Entity relationships

Role of Frameworks - Rules

• Drools and MVEL based
• Condition expression parser
• Evaluation based on Drools or MVEL
• Actions are java implementations.
• Supports chaining of conditions.
• UI to build conditions.

Role of Frameworks - Batch
