Microservice Conversion Opportunities with nOps Discovery

Overview​

nOps Discovery identifies opportunities to decompose monolithic applications into microservices as part of your migration journey. By analyzing application architecture, code dependencies, and runtime behavior, our platform provides data-driven recommendations for breaking down complex applications into modular, independently deployable services that can take full advantage of cloud-native features and enable more agile development.

Important

nOps Discovery identifies and analyzes microservice conversion opportunities but does not execute the actual conversion process. The implementation requires specialized tools (such as vFunction) and/or service providers with expertise in application modernization. nOps can recommend qualified partners to assist with the actual conversion process.

Monolith Identification​

Application Architecture Analysis​

nOps Discovery employs multiple techniques to identify monolithic applications in your environment:

Static Detection Methods​

  1. Deployment Pattern Recognition:

    • Single-artifact deployment signatures
    • Large application server footprints
    • Consolidated database access patterns
    • Unified logging and configuration

  2. Resource Allocation Analysis:

    • Oversized VM requirements
    • Scaling inefficiencies
    • Resource utilization imbalances
    • All-or-nothing deployment patterns

  3. Technology Stack Assessment:

    • Legacy application server technologies (WebSphere, WebLogic, JBoss, etc.)
    • Outdated framework versions
    • Monolithic framework signatures (Spring MVC, Struts, etc.)
    • Traditional n-tier architecture patterns

Runtime Behavior Indicators​

  1. Process Behavior Analysis:

    • Single-process handling of diverse functionalities
    • Long-running process lifetimes
    • Comprehensive restart requirements
    • Shared memory usage across functions

  2. Performance Pattern Detection:

    • Global impact from localized load
    • Uniform resource utilization
    • Non-granular scaling capabilities
    • Resource contention signatures

  3. Service Interaction Mapping:

    • Limited external service boundaries
    • Internal function calls vs. service calls
    • Shared session management
    • Lack of clear domain boundaries

Decomposition Potential Assessment​

Once monolithic applications are identified, nOps Discovery evaluates their suitability for microservice conversion:

Deep Code Introspection (With Permission)​

When customers opt-in to allow AI-powered code analysis, nOps can perform significantly more accurate microservice conversion assessment:

  1. Advanced Structural Analysis:

    • Precise package and namespace organization mapping
    • Detailed class hierarchy and inheritance pattern detection
    • Identification of implicit and explicit service boundaries
    • Complete internal API structure mapping

  2. Comprehensive Dependency Analysis:

    • Class and method-level dependency graphing
    • Exact method invocation pattern detection
    • Full shared utility usage mapping
    • Complete data model dependency analysis

For full details on the AI technology, security measures, and how to enable this feature, see the Deep Code Introspection documentation.

Runtime Behavior Analysis​

For all applications, regardless of code access permission:

  1. Transaction Flow Tracing:

    • User journey mapping
    • Request processing paths
    • Function execution patterns
    • Response assembly flows

  2. Data Access Pattern Analysis:

    • Database access patterns
    • Table ownership patterns
    • Transaction isolation levels
    • Data consistency requirements

  3. Resource Utilization Profiling:

    • CPU utilization by function
    • Memory allocation patterns
    • I/O utilization distribution
    • Network traffic concentration

  4. Temporal Execution Analysis:

    • Function execution frequency
    • Execution timing relationships
    • Batch vs. real-time processing
    • Event propagation patterns
