Supporting & Operating Large-Scale InterSystems IRIS
Specialized contract engineering and operational leadership for mission-critical InterSystems IRIS, HealthShare, and cloud-native Kubernetes workloads. Delivering high-availability mirroring, deep-dive performance diagnostics, and zero-downtime legacy modernizations.
InterSystems Kubernetes Operator (IKO)
Automated topology deployment, rolling upgrades, and cluster lifecycle management using custom IrisCluster resources.
- • Declarative multi-node cluster topologies: mirrored data nodes, distributed caching via Enterprise Cache Protocol (ECP), and sharded analytics engines.
- • GitOps continuous delivery with zero-downtime rolling upgrades and containerized maintenance workflows across any Kubernetes platform.
- • Dynamic persistent volume management, CSI multi-volume storage layouts, and non-disruptive volume resizing.
- • Enterprise Kubernetes orchestration on Google Cloud (GKE), AWS (EKS), Azure (AKS), and on-premise OpenShift/Kubernetes.
High Availability & Data Protection
Architected for continuous 24/7 database availability, split-brain protection, and zero data loss recovery.
- • Synchronous failover mirroring paired with ISCAgent Arbiter for instant, automated failover without split-brain risk.
- • Disaster recovery (DR) async nodes and reporting async members to offload heavy analytical queries from OLTP primary.
- • Storage-grade zero-impact backups utilizing external Freeze/Thaw APIs (SYS.Database.Freeze/Thaw) for storage snapshot integration.
- • Write Image Journal (WIJ) health monitoring, primary/alternate journal directory failover, and crash recovery safety.
Performance Tuning & Diagnostics
Deep-dive diagnostic analysis and configuration tuning to maximize throughput and resolve resource contention.
- • Diagnostic profiling and bottleneck isolation using ^SystemPerformance (pButtons), ^PERFMON, and messages.log telemetry.
- • Configuration Parameter File (iris.cpf) optimization: tuning global buffers (globals), routine buffers, locks, and shared memory (gmheap).
- • Process contention and concurrency management: lock table deadlock resolution (^LOCKTAB) and semaphore optimization.
- • Scheduled database integrity audits (^Integrity), block allocation checks, and enterprise security hardening (RBAC & TLS).
Legacy Modernization & Support
Bridging technical talent gaps with senior operational leadership for mission-critical healthcare and enterprise IT.
- • Low-risk migrations from legacy Caché, Ensemble, and MUMPS to modern InterSystems IRIS Data Platform & IRIS for Health.
- • Production cutover planning, data reconciliation, interface verification (HealthShare & Health Connect), and go-live leadership.
- • Fractional systems leadership: augmenting internal teams during high-stakes implementations, upgrades, and platform scaling.
- • Rapid incident triage, 24/7 on-call escalation support, and root-cause remediation for production outages.
Flexible Operational Engagement Models
Whether augmenting an internal engineering team during a high-stakes cutover, migrating legacy environments, or providing ongoing fractional platform operations, engagements are structured for maximum technical impact and zero business disruption.
Fractional / Contract Systems Operator
Dedicated senior operational lead embedded with your engineering team to manage, monitor, and maintain enterprise IRIS clusters.
IKO & Cloud Migration Architect
Modernizing legacy on-premises workloads into automated, scalable Kubernetes topologies with GitOps CI/CD.
Emergency Performance & Diagnostic Triage
Deep-dive pButtons health audits to resolve locking deadlocks, buffer thrashing, and high-concurrency database stalls.
Zero-Downtime Migration & Cutover Lead
End-to-end execution of platform upgrades from Caché/Ensemble to IRIS for Health with zero data loss.
