My production Kubernetes cluster needs hands-on assistance migrating the networking layer from its current, rather intricate CNI to either Cilium (eBPF with WireGuard) or Calico with WireGuard encryption. The overriding goal is a seamless, zero-downtime cut-over while preserving all of our existing custom NetworkPolicies—east-west, ingress, and egress traffic must continue to behave exactly as it does today. Scope of work The engagement starts with a deep-dive into the present topology, routing rules, and policy objects. From there, a step-by-step migration playbook and rollback plan must be crafted, executed first in staging, then in production. Once live, I need empirical data that compares both solutions: latency, throughput, CPU and memory overhead, and encryption overhead und...

I need a complete examination system that runs entirely over our local Windows network, so students can sit an “online” test without any internet connection.

I have an old FreeBSD installation that boots; I copied the entire disk image onto a USB drive and now need the document files extracted. The priority is .doc and .pdf documents that were kept inside a handful of specific directories (I’ll send their full paths once we start). The job is simple in scope but requires solid FreeBSD / UFS-2 recovery know-how. You will need to: • Mount or image-clone the USB safely (read-only first). • Locate the requested directories and pull every .doc and .pdf you can find. • Verify file integrity—open the recovered documents or run hash checks so I know they are intact. • Package the results in a tidy archive and hand it back to me, along with a brief log of what you did (commands, tools, and any issues encountere...

I’ll grant you limited IAM access; after each maintenance window I expect a short summary of wh...

My outbound mail reaches Gmail and every other provider perfectly, yet anything sent to Outlook, Hotmail or (Microsoft) still heads straight to junk or they don’t get it at all . The domain is hosted on delicated server from and I have full access to all DNS and server-side settings, so making technical changes is not an issue. SPF, DKIM and DMARC are already correctly published and passing; Microsoft support tickets have been opened more than once, and I have tweaked header settings, sending patterns and content, but the problem always returns. I want a definitive fix that keeps the domain off Microsoft’s spam list for good, not a temporary workaround. Here is what I need from you: • A comprehensive audit of my current configuration, including header analysis, send...
