Container & Serverless Opportunities with nOps Discovery

Overview​

nOps Discovery goes beyond traditional "lift and shift" migrations by identifying workloads that can benefit from containerization or serverless architectures. By analyzing application characteristics, usage patterns, and—when permitted—source code, nOps provides actionable recommendations for modernizing your applications during migration to maximize cloud benefits.

Containerization Assessment​

Commercial Off-The-Shelf (COTS) Applications​

nOps Discovery maintains a comprehensive knowledge base of commercial applications and their containerization potential:

COTS Evaluation Process​

  1. Application Identification:

    • Fingerprinting of installed software against our database of 10,000+ commercial applications
    • Version detection and compatibility assessment
    • License validation for container-compatible licensing

  2. Containerization Suitability Analysis:

    • Vendor containerization support status
    • Official container image availability
    • Known containerization limitations or issues
    • Configuration complexity assessment

  3. Runtime Behavior Analysis:

    • State management requirements
    • Filesystem access patterns
    • Environment variable dependencies
    • Required system access and permissions

Container Migration Recommendation​

For suitable COTS applications, nOps provides:

  • Container Implementation Plan:

    • Recommended container image and version
    • Required configuration adjustments
    • Data persistence strategy
    • Network access considerations

  • Deployment Options:

    • Amazon EKS vs. Fargate recommendation based on:
      • Instance type requirements
      • Scaling patterns
      • Management overhead tolerance
      • Cost optimization opportunities

    • Confidence score for successful containerization
    • Potential challenges and mitigations
    • Testing and validation approach
    • Rollback strategy

Custom Applications​

For custom-developed applications, nOps Discovery employs two distinct analysis approaches:

Deep Code Introspection (Opt-in)​

When customers opt-in to allow AI-powered code analysis, nOps provides enhanced containerization assessment:

  1. Advanced Container Compatibility Assessment:

    • Identification of container-incompatible dependencies through static code analysis
    • System call and resource access pattern detection
    • Hard-coded paths and configuration references
    • Environment-specific assumptions and dependencies

  2. Automatic Containerization Assets:

    • Tailored Dockerfile generation optimized for the specific application
    • Required system packages identification based on actual imports
    • Multi-stage build optimizations for smaller, more secure images
    • Dependency installation and caching optimization
    • Security hardening recommendations based on application needs
    • Container configuration appropriate for the application architecture

For full details on how nOps uses AI to analyze your code securely, see the Deep Code Introspection documentation.

Behavioral Analysis (Without Code Access)​

When deep code introspection is not permitted:

  1. Runtime Behavior Observation:

    • Process execution patterns
    • Filesystem access monitoring
    • Network communication mapping
    • Resource utilization patterns

  2. Technology Stack Identification:

    • Detection of modern runtimes (Node.js, Python, Ruby, Java, etc.)
    • Web server and application server fingerprinting
    • Framework identification through behavioral signatures
    • Database and external service dependencies

  3. Statelessness Evaluation:

    • File system write pattern analysis
    • Local cache usage detection
    • Session storage approach identification
    • Data persistence requirements assessment

  4. Containerization Confidence Scoring:

    • High-confidence candidates identified based on:
      • Modern language runtimes
      • Standard web application patterns
      • Limited or well-structured file system access
      • Clear external dependency patterns

Container Platform Recommendations​

Based on the containerization assessment, nOps recommends the most appropriate container platform:

Amazon EKS​

Recommended for:

  • Complex applications with specific scheduling requirements
  • Applications needing advanced networking capabilities

Recommended for:

  • Applications where management simplicity is paramount
  • Workloads with predictable resource needs
  • Containers needing minimal operational overhead
  • Dev/test environments requiring rapid deployment
  • Applications with straightforward networking requirements
  • Workloads benefiting from precise per-container billing

Serverless Opportunity Assessment​

Beyond containerization, nOps Discovery identifies functions and services that could benefit from a serverless approach:

Serverless Candidates Identification​

  1. Function Isolation Analysis:

    • Detection of independently deployable functions

  2. Statelessness Verification:

    • Detection of pure functions without side effects
    • Analysis of in-memory state management
    • Identification of external state dependencies
    • Temporary storage usage patterns

  3. Resource Utilization Patterns:

    • Execution frequency and predictability
