Open Microservices, DDS Middleware & Submarine Data Interfaces Training by Tonex
Distributed software services are only interoperable when their messaging contracts address data meaning, delivery behavior, timing, and change. This course examines microservice decomposition, Data Distribution Service (DDS) middleware concepts, publish-subscribe information exchange, quality of service policies, and submarine data interface engineering. Participants compare service boundary choices with latency and reliability requirements and learn to define robust interface specifications across evolving suppliers. The curriculum emphasizes verified semantic interoperability, observability, failure behavior, and controlled version changes rather than connectivity alone.
Cybersecurity is affected by who may publish, subscribe, or alter mission information. Trusted middleware improves cybersecurity through authenticated participants, authorized data flows, secured transport, and well-managed access policies.
The practical training approach includes exercises, real-world case studies, and examples of processes and documentation used in submarine software engineering projects, including data dictionaries, DDS topic definitions, quality-of-service profiles, and interface change control records.

Course Modules
Module 1: Microservice Architecture and Contract Design
- Define independently managed services around coherent processing responsibilities
- Identify dependencies among service discovery, configuration, and shared data
- Distinguish service boundaries from simple code packaging conventions
- Specify request and event contracts with versioned behavioral expectations
- Evaluate network and orchestration overhead within embedded resource limits
- Document integration responsibilities between separately managed service providers
Module 2: DDS Middleware Architecture and Terminology
- Describe domain participants, publishers, subscribers, topics, and data readers
- Explain discovery and data exchange at a conceptual integration level
- Compare middleware abstraction with application-specific transport assumptions
- Identify how DDS implementations differ in supported features and behavior
- Define data type and topic naming conventions for interoperability
- Map middleware configuration dependencies to subsystem deployment baselines
Module 3: Quality of Service and Timing Policies
- Interpret reliability, durability, history, and deadline policy objectives
- Evaluate latency, freshness, and bounded queueing requirements
- Assess tradeoffs between reliable delivery and constrained resource use
- Review liveliness detection and stale publisher information handling
- Choose policy configurations based on documented information needs
- Verify message behavior under controlled degraded communication conditions
Module 4: Schema Governance and Data Interoperability
- Define data dictionaries and field semantics for shared mission information
- Distinguish syntax compatibility from equivalent operational data meaning
- Develop controlled topic schema evolution and consumer compatibility rules
- Plan translation boundaries where legacy and modern formats coexist
- Document timestamp, units, provenance, and validity metadata expectations
- Establish review processes for cross-supplier data contract changes
Module 5: Integration Verification and Service Resilience
- Design publish-subscribe interoperability verification across supplier components
- Examine loss, delay, duplication, and out-of-order delivery cases
- Evaluate behavior when discovery or supporting services become unavailable
- Capture message tracing and diagnostics without disrupting timing objectives
- Record acceptance evidence for data and quality-of-service compliance
- Develop recovery and regression criteria after interface or middleware upgrades
Module 6: Secure Middleware and Access Governance
- Identify trust relationships among discovered DDS domain participants
- Apply authentication and topic-level authorization where supported
- Review secure key and credential distribution dependencies
- Evaluate data integrity and confidentiality for approved information exchanges
- Assess exposed diagnostic interfaces and unauthorized subscription risks
- Document cybersecurity controls as part of middleware integration assurance
