Virtualization Jobs

Computing & Networks Foundations Trainer, Role purpose Build the mental model every later course relies on: how computers execute work, how operating systems manage it, how data is represented, and how machines communicate. The successful trainer will teach students to diagnose faults by evidence and layer instead of guessing. Topics you will lead 1. How a computer executes work 2. Operating systems and processes 3. The filesystem and command line 4. Numbers, text, and encoding 5. How networks move data 6. The internet protocol stack 7. HTTP and the web 8. Client, server, and system structure 9. Virtualisation and containers 10. Reading an unfamiliar system 11. Power, connectivity, and local constraints 12. Structured diagnosis of a broken machine Subject-specific profile - Stron...

Our stack runs on a mix of Proxmox VMs, bare-metal Linux, and Docker containers that host several resource-intensive workloads (WordPress sites, small AI services, internal tools). Performance has started lagging, so the goal is a measurable speed-up across the board—CPU, memory, disk I/O, and network throughput. Scope of the optimisation • Server side: fine-tune Proxmox (kernel parameters, storage back-ends, CPU pinning) and harden the underlying Linux hosts, making sure Docker containers inherit those gains. • Network side: analyse current routing, bridges, VLANs and SDN overlays, then remove bottlenecks and reduce latency between VMs, containers and external clients. • Application side: profile the heaviest WordPress and AI containers, tweak PHP-FPM, databas...

I need seasoned help with infrastructure management, but not at the network edge—at the cloud-server layer that keeps all our applications running. The environment is 100 % cloud, so every task you take on will involve instances, storage volumes, security groups, load balancers, and the automation that ties them together. What I expect: • Assess the current fleet of cloud servers, documenting configuration, performance baselines, and any immediate risks. • Introduce or refine automated build, patch, and backup routines (Terraform, Ansible, or comparable tooling—your choice, provided it is fully scriptable and repeatable). • Implement monitoring and alerting that shows real-time health and clear historical trends; integration with Grafana or CloudWatch is pre...

I need a purpose-built Ubuntu-based server image that installs cleanly and starts working straight away—no desktop layer, no local login, just an install-only ISO that I can hand to datacentre staff. Core stack that must be pre-integrated and verified: • accel-ppp compiled with all typical modules • PHP 8.4 with common extensions • iptables set as the default packet filter (nftables disabled) • FRR routing suite ready for BGP/OSPF configuration • OpenSSH enabled for remote administration (key auth only, root login disabled) Security hardening is critical. I want console TTYs disabled, no greeter or graphical login, and all unused services masked. The built image should ship with an opinionated firewall policy that blocks everything except the port...
