OCI Administrator - Onsite

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.
