PalC's private and hybrid cloud work focuses on building platforms where compute, networking, security, and orchestration are tightly aligned - enabling predictable performance, strong isolation, and operational clarity. This approach is shaped by real deployments where on-premises control is mandatory, data sovereignty and compliance are non-negotiable, and networking behaviour matters as much as compute capacity.

Core Capabilities

Depth across private, hybrid, and cloud-native platforms

PalC covers the full private and hybrid cloud engineering stack - from sovereign platform design and Kubernetes-centric infrastructure through high-performance networking and AI-ready compute.

01

Private & Sovereign Cloud Platforms

Design and delivery of on-premises cloud platforms providing cloud-like provisioning while retaining full control over infrastructure, networking, and data - aligned with strict compliance and data residency requirements.

  • Sovereign cloud platform design for government and regulated sectors
  • Air-gapped and isolated environment engineering
  • Multi-tenant VPC, VM, and container workload management
  • RESTful API-driven provisioning with OpenAPI / Swagger
  • RBAC and identity-integrated access control
02

Hybrid Cloud Architecture & Networking

Design of hybrid environments integrating on-premises platforms with AWS, Azure, and GCP - using consistent networking, security, and policy models that reduce fragmentation and operational drift.

  • Secure hybrid connectivity - SD-WAN, DirectConnect, ExpressRoute
  • IPSec tunnel design using StrongSwan for encrypted inter-cloud links
  • Policy-consistent networking across on-premises and cloud workloads
  • Unified identity and RBAC across hybrid environments
  • Terraform-based IaC and GitOps for hybrid infrastructure
03

Cloud-Native Networking & Security

Advanced virtual networking, traffic segmentation, load balancing, and policy enforcement aligned with cloud-native workloads - using eBPF-based Cilium, VPP acceleration, and XDP for high-performance data paths.

  • Cilium eBPF-based networking and network policy for Kubernetes
  • VPP for high-throughput virtual switching and routing
  • XDP packet acceleration for latency-sensitive workloads
  • SONiC-based open underlay networking for private cloud fabrics
  • SmartNIC and DPU offload for network function acceleration
04

Kubernetes-Centric Platform Engineering

Design and operation of Kubernetes-based platforms where networking, security, and observability are first-class concerns - with GitOps delivery, service mesh, and multi-cluster federation from day one.

  • Bare-metal and virtualised Kubernetes cluster deployment
  • Service mesh integration - Istio or Cilium service mesh
  • GitOps delivery - ArgoCD and Flux with Helm and Kustomize
  • OPA Gatekeeper policy enforcement at admission time
  • Multi-cluster federation and workload portability
05

High-Performance & AI-Ready Platforms

Cloud platforms engineered to support GPU workloads, AI pipelines, and performance-sensitive applications - with RoCE v2, RDMA, NVMe-oF storage access, and DPU-accelerated data paths.

  • GPU-enabled Kubernetes platforms for training and inference
  • RoCE v2 and lossless fabric configuration for GPU communication
  • NVMe-oF and high-throughput storage network integration
  • Marvell-class DPU / SmartNIC platform engineering
  • Latency-optimised networking for real-time AI serving
06

Observability & Platform Operations

Telemetry, flow-based monitoring, and integrated logging pipelines built into the platform from day one - with Prometheus, Grafana, and automation-driven configuration management ensuring operational clarity at scale.

  • Prometheus and Grafana for platform-wide metrics and alerting
  • Flow-based network telemetry and anomaly detection
  • Integrated logging pipeline - Loki, Elasticsearch, or custom
  • Automation-driven configuration management - Ansible, Terraform
  • SRE runbooks and platform health dashboards

Technical Deep Dive

Proven engineering across networking, security, and orchestration

PalC engineers work at the intersection of platform, networking, and application layers - configuring Cilium network policies, VPP data planes, and GitOps delivery pipelines in production environments.

eBPF Networking - Cilium Network Policy

Identity-aware Kubernetes networking with Cilium

L3/L4/L7 network policy enforcement using eBPF - no iptables, lower latency, and full DNS-aware and HTTP-aware egress control.

GitOps - ArgoCD Application Delivery

Infrastructure and workloads as code - end to end

Every platform resource declared in Git - Terraform provisions infrastructure, ArgoCD delivers application workloads with self-healing and drift detection.

# ArgoCD - private cloud app sync

VPP - Virtual Packet Processing

High-throughput virtual switching for private cloud

VPP (Vector Packet Processor) delivers multi-Gbps packet forwarding in software - enabling high-throughput vSwitch, vRouter, and NAT in private cloud environments without hardware ASIC dependency.

# VPP - private cloud vSwitch config

IPSec - Hybrid Cloud Connectivity

StrongSwan IPSec for encrypted hybrid links

IKEv2 / IPSec tunnels between on-premises private cloud and public cloud VPCs - policy-based routing with certificate-based authentication and AES-GCM encryption at line rate.
