Oci Administrator - Onsite

OCI Administrator - Onsite1 **Focus:** OCI & AWS Multi-Cloud Architecture **Role Overview** * Manage, configure, and troubleshoot Oracle Cloud Infrastructure (OCI) with a heavy focus on OCI-to-AWS multi-cloud architecture. * Architect and maintain high-performance multi-cloud network connectivity leveraging OCI Virtual Cloud Networks (VCNs) and Dynamic Routing Gateways (DRGs). * Ensure high availability, security, performance, and cost optimization across OCI and AWS environments. **Core Multi-Cloud Networking & Administration** * Administer OCI core infrastructure (Compute, Storage, Autonomous/Exadata DBs) alongside interconnected AWS resources (VPCs, EC2, S3). * Design and manage OCI Virtual Cloud Networks (VCNs), subnets, route tables, Security Lists, and Network Security Groups (NSGs). * Configure and maintain OCI Dynamic Routing Gateways (DRGs) to manage all multi-cloud traffic routing between OCI VCNs and AWS VPCs. * Establish and maintain low-latency, cross-cloud connectivity between OCI and AWS using OCI FastConnect and AWS Direct Connect (or IPsec VPN tunnels) via DRGs for split-stack applications (e.g., AWS App Tier connected to OCI Database Tier). * Implement DRG Transit Routing strategies, acting as a central routing hub for multi-VCN OCI setups connected to AWS environments. * Manage VCN peering (Local/Remote) and DRG attachments across multiple OCI tenancies and AWS regions. * Optimize multi-cloud network routing using BGP, custom DRG route tables, route distributions, and Equal-Cost Multi-Path (ECMP) routing for active-active redundancy. **Technical Support & Troubleshooting** * Provide tier-2/3 technical support, diagnosing and resolving complex issues across OCI and AWS multi-cloud setups. * Troubleshoot DRG routing anomalies, BGP session drops, FastConnect/Direct Connect performance degradation, and cross-cloud latency issues. * Lead technical root-cause analysis (RCA) and coordinate directly with Oracle and AWS vendor support teams for critical outages. * Monitor multi-cloud system metrics, bandwidth utilization, and log traces to maintain maximum uptime and performance. **Security, Automation, & Modern Tooling** * Provision and manage multi-cloud infrastructure (OCI VCNs, DRGs, AWS VPCs) using HashiCorp (HCP) Terraform Cloud and Ansible. * Monitor, detect, and automatically remediate cloud security risks using Oracle Cloud Guard in OCI. * Implement Zero-Trust Network Access (ZTNA) and secure privileged access management across OCI and AWS using Teleport. * Enforce secure network perimeters, egress filtering, and web security using Zscaler. * Manage identity, access controls, IAM policies, and cross-cloud trust mechanisms across OCI PaaS/SaaS and AWS IAM. **Operational Excellence & Collaboration** * Work alongside Cloud Engineers, DevOps, and business teams to align OCI-AWS multi-cloud architecture with operational goals. * Recommend and implement continuous cost-optimization strategies (e.g., managing OCI-to-AWS egress traffic fees, right-sizing compute/storage). * Maintain complete operational documentation, including OCI-AWS network topology diagrams, DRG routing tables, runbooks, and disaster recovery procedures.
