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 Fast Connect 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, Fast Connect/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 Hashi Corp (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, Dev Ops, 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.
