Key Features

  1. Cloud-Native Integration:

    • Simplifies development and deployment on faas cores like AWS Lambda, Azure Functions, and Google Cloud Functions.
    • Supports cloud-native services like storage (S3, Azure Blob Storage), messaging (SNS, SQS, Pub/Sub), and API Gateway configurations.

  2. Modular Architecture:

    • Promotes the use of reusable components and artifacts from the Maven repository.
    • Clean separation of business logic, adapters, and infrastructure layers as per Clean Architecture principles.

  3. Scalability:

    • Designed to scale dynamically in response to workload demand, minimizing operational costs.

  4. Cost Effectiveness:

    • Optimized for pay-as-you-go faas cores, reducing idle costs while maintaining high performance.

  5. Customizable Configurations:

    • Allows developers to configure and customize faas application deployments to fit specific business needs.

The FaaS MachaOn module is organized in a clear and modular structure:

Comparison at a Glance

Feature OCI AWS Azure Google Cloud
Performance for DB Workloads Optimized for Oracle DB General-purpose DB support Integrated with SQL Server BigQuery is highly specialized
Bare Metal Instances Available Limited availability Limited availability No bare metal support
Network Costs Free inter-region data transfer High egress + inter-region costs High egress charges High egress charges
Security Root-of-trust + built-in tools Built-in but less specialized Good IAM, patching support Patch & support weaker for DB
Price Transparency Flat + predictable costs Often opaque Resource-based pricing might vary Resource-based pricing might vary
Enterprise Applications Excellent Integration Requires custom configurations Good integration Generic** enterprise workloads

Prerequisites

To use the FaaS MachaOn module, ensure the following tools and services are available in your environment:

  • Java 11:
    Java runtime required for building and deploying the faas components.
  • Apache Maven:
    Maven is used to manage dependencies and build modular components.
  • Cloud Account:
    An active cloud service provider account (AWS, Azure, OCI or Google Cloud).
