Production Deployment Workflow

Phase 1: Pre-Deployment Preparation

1. Review Production Checklist

  • Complete all items in the Production Checklist
  • Verify all security configurations
  • Test authentication and authorization
  • Validate TLS configuration
  • Confirm backup procedures

2. Security Hardening

  • Implement Security Hardening recommendations
  • Network isolation and firewalls
  • Remove demo configurations
  • Configure strong authentication
  • Enable audit logging
  • Secure secrets management

3. Performance Optimization

  • Review Performance Tuning guidelines
  • Establish performance baselines
  • Optimize DLS/FLS queries
  • Configure caching
  • Test with production-like load

Phase 2: Deployment

1. Deploy Infrastructure

  • Provision production servers
  • Configure network and security groups
  • Install Elasticsearch and Search Guard
  • Configure TLS certificates

2. Configure Search Guard

  • Upload production configuration (roles, users, role mappings)
  • Verify authentication works
  • Test authorization policies
  • Enable audit logging
  • Configure monitoring

3. Load Data

  • Restore from snapshots OR
  • Begin indexing production data
  • Verify data access controls
  • Test search functionality

Phase 3: Post-Deployment

1. Monitoring Setup

  • Configure Production Monitoring
  • Set up alerts for security events
  • Configure performance monitoring
  • Enable health checks
  • Verify audit logs flowing

2. Backup Validation

  • Test Backup and Recovery procedures
  • Verify configuration backups
  • Test snapshot restore
  • Document recovery procedures
  • Schedule regular DR drills

3. Operational Readiness

  • Train operations team
  • Document runbooks
  • Define escalation procedures
  • Establish maintenance windows
  • Plan for certificate rotation

Production Architecture Considerations

High Availability

Cluster Configuration:

  • Minimum 3 master-eligible nodes
  • Replica shards for all indices
  • Cross-availability zone deployment
  • Load balancer for client connections

Fault Tolerance:

  • Node failure recovery
  • Split-brain prevention
  • Automated failover
  • Rolling restart capability

Scalability

Horizontal Scaling:

  • Add data nodes for capacity
  • Distribute load across nodes
  • Use dedicated master nodes
  • Separate roles (master, data, coordinating)

Vertical Scaling:

  • Appropriate heap size (30GB max recommended)
  • Sufficient CPU for encryption overhead
  • Fast disks (SSD) for performance
  • Network bandwidth for cluster communication

Security Layers

Defense in Depth:

  1. Network Layer - Firewalls, VPNs, security groups
  2. Transport Layer - TLS encryption, client certificates
  3. Authentication Layer - Multi-factor authentication, strong passwords
  4. Authorization Layer - Role-based access control, least privilege
  5. Data Layer - Document/field-level security, field masking
  6. Audit Layer - Comprehensive logging, immutable audit trails

Production Monitoring Dashboards

Key Metrics to Track:

Metric Target Alert Threshold
Cluster status Green Yellow or Red
Failed login attempts < 5 per user/hour > 5 in 5 minutes
Certificate expiration > 30 days < 30 days
JVM heap usage < 75% > 85%
Search latency (p99) < 100ms > 200ms
Audit log queue < 50% full > 80% full
Disk space > 20% free < 15% free

Common Production Challenges

Challenge 1: Performance Degradation

Symptoms:

  • Slow search queries
  • High JVM heap usage
  • Increased GC time

Solutions:

  • Review Performance Tuning
  • Optimize DLS/FLS queries
  • Increase authentication cache size
  • Add nodes to cluster
  • Review audit logging overhead

Challenge 2: Security Events

Symptoms:

  • Multiple failed logins
  • Unauthorized access attempts
  • TLS errors

Solutions:

Challenge 3: Certificate Management

Symptoms:

  • Certificate expiration warnings
  • TLS handshake failures
  • Client connection errors

Solutions:

  • Use TLS Hot Reload for rotation
  • Automate certificate renewal
  • Monitor certificate expiration (30-day warning)
  • Maintain certificate inventory
  • Test certificate rotation in staging

Challenge 4: Configuration Drift

Symptoms:

  • Inconsistent behavior across environments
  • Undocumented changes
  • Configuration conflicts

Solutions:

  • Use version control for configuration files
  • Implement change management process
  • Regular configuration backups
  • Use Configuration Change Tracking
  • Automated configuration validation
