MACH Architecture & Modules

How does the platform respond to failures of individual modules? ›

If a module fails, redundant instances automatically take over its tasks. The load balancing system distributes requests dynamically until the affected service is restored. Errors are logged and displayed in the dashboard.

How are deployments managed during high-load periods without impacting users? ›

Deployments use blue-green or canary strategies. Old and new versions run in parallel until the new version is fully validated. Users do not experience interruptions or downtime.

How does the system detect potential security incidents or attacks? ›

An intrusion detection system (IDS) analyzes network traffic and API calls for suspicious patterns. If anomalies are detected, warnings are generated automatically and the affected service is isolated.

How are versions and dependencies between modules managed? ›

All modules are versioned and have clear dependency definitions. Changes to core modules require approvals in version management to prevent compatibility issues. Older versions remain available for backward compatibility.

Which standards apply to the development of internal modules? ›

All internal modules must be built on REST or GraphQL and support JSON as an exchange format. Binding coding guidelines, logging requirements, and naming conventions also apply.

How does the MACH architecture support horizontal and vertical scaling? ›

Because modules are decoupled, the platform can scale horizontally (more containers) as well as vertically (more resources per container). The load balancing system distributes requests automatically to ensure stable performance.

How are infrastructure resources dynamically managed in the cloud? ›

A central orchestration system automatically scales CPU, RAM, and storage based on current system load. This optimizes costs and ensures sufficient resources during peak loads.
