OpenNebula Expert for Private/Hybrid Cloud

We are engaging a freelance OpenNebula expert to build and operate a scalable private/hybrid cloud environment. The scope includes initial assessment, deployment, integration with storage/networking, automation, monitoring, and a handover.

B. Detailed Scope
Assessment & Planning

Audit existing infrastructure (if any).

Define architecture (controllers, hypervisors, storage, network layout).

Recommend high availability and multi-tenant strategy.

Deployment

Install OpenNebula (controller and compute nodes).

Configure virtualization backend (KVM/Xen) on hypervisors.

Integrate Ceph or other storage backend with OpenNebula.

Set up networking: bridges, VLANs, security policies.

Configure authentication/authorization (e.g., LDAP/SSO).

Automation & Templates

Create reusable VM templates.

Automate lifecycle (provision, scale, decommission) via scripts or OpenNebula features.

Optionally integrate with CI/CD or external APIs.

Operationalization

Set up monitoring, logging, and alerting (e.g., health of hosts, storage usage).

Implement backup/restore procedures for VM images.

Define and implement upgrade/migration process.

Security & Hardening

Apply best practices (SSH hardening, firewall rules, role separation).

Secure API endpoints and credentials.

Documentation & Handover

Architecture diagrams.

Installation and configuration guides.

Runbooks for common operations and incident response.

Training session with in-house team.

C. Required Freelancer Profile
3+ years in cloud infrastructure, with at least 1+ year focused on OpenNebula.

Demonstrated implementations of OpenNebula with storage (Ceph) and networking.

Strong Linux sysadmin skills.

Experience with automation (Python/Bash).

Clear communicator and able to produce crisp documentation.

D. Engagement Terms
Duration: e.g., 4–8 weeks initial engagement + optional ongoing support.

Billing: Hourly rate or fixed milestones (define deliverables per milestone).

Availability: Overlap with [your time zone/preferred working hours].

Deliverables tied to acceptance criteria.

E. Evaluation / Sample Technical Task
Provide a small paid test such as:

“Set up a mini OpenNebula lab with 1 controller and 2 hypervisors using Ceph as shared storage. Provision a VM from a template and demonstrate scaling it.”

Ask for a short write-up: how HA would be achieved, and how you’d recover from a failed compute node.
