About Arunkumar Balamurugan

I architect cloud infrastructure that enterprises actually trust — resilient, secure, and built to scale. With 10+ years of hands-on experience across Oracle Cloud Infrastructure (OCI) and Microsoft Azure, I specialize in designing and delivering end-to-end cloud networking, hybrid cloud architectures, and large-scale infrastructure migrations for enterprise customers. My work sits at the intersection of deep technical execution and strategic cloud consulting, translating complex business requirements into production-grade cloud solutions.What I do best:1. OCI Networking & Architecture — VCN design, DRG, FastConnect, IPSec VPN, LPG, RPC, Load Balancers, DNS, Security Gateways — from whiteboard to production.2. Hybrid & Multi-Cloud — Seamlessly integrating OCI, Azure, and on-premises environments into unified, secure connectivity architectures.3. Cloud Migration at Scale — Led 30+ enterprise migration programs using OCM, RackWare, and VMware HCX, covering on-premises, VMware (OCVS), and legacy workload transitions.4. IaaS / PaaS / SaaS Integration — Designed Oracle Integration Cloud (OIC) solutions bridging cloud-native, SaaS, and third-party platforms with secure API and IAM federation.5. Security & Governance — OCI IAM, NSG, WAF, Cloud Guard, KMS, Vault — security-by-design baked into every architecture layer.6. HA/DR Architecture — Multi-region, multi-AD deployments with OCI Full Stack Disaster Recovery (FSDR) and automated failover.Beyond the technical depth, I bring a strong customer-facing consulting mindset, leading architecture workshops, executive stakeholder discussions, and cross-functional delivery teams. I\'ve acted as a trusted cloud advisor for enterprise clients across multiple industries, ensuring not just technical delivery but real business outcomes.Currently holding 8 active OCI 2025 certifications, including Architect Professional, Networking Professional, Security Architect, and Multicloud Architect; reflecting both breadth and depth of cloud expertise.
