Most IT companies treat Linux as an afterthought. We treat it as a core competency. Petronella Technology Group provides deep Linux expertise for server infrastructure, security hardening, containers, cloud platforms, database administration, and DevOps automation -- backed by 24+ years of real-world deployment experience.
Linux powers over 96% of the world's top web servers, runs the majority of cloud infrastructure on AWS, Azure, and GCP, and forms the foundation of container platforms like Docker and Kubernetes. If your business uses cloud services, runs web applications, or relies on databases like PostgreSQL, MySQL, or MongoDB, Linux is part of your critical infrastructure.
The challenge is that Linux expertise is rare in the managed IT services industry. Most MSPs focus exclusively on Windows environments and either cannot support Linux or treat it as a specialty case with higher rates and longer response times. This leaves businesses that rely on Linux infrastructure -- particularly those running AI/ML workloads, web applications, or hybrid environments -- underserved.
Petronella Technology Group was built on Linux. Our founder Craig Petronella holds CCNA and CWNE certifications alongside deep Linux systems expertise dating back to the early 2000s. We run our own infrastructure on NixOS, Proxmox, and Debian, and we support client environments spanning RHEL, Ubuntu, CentOS, Rocky Linux, Alpine, and specialized distributions for AI and HPC workloads.
Advanced Linux expertise for enterprise environments, not just basic administration.
High-availability clusters with Pacemaker/Corosync, load balancing with HAProxy and nginx, LVM and ZFS storage management, NFS/CIFS file sharing, and performance optimization for CPU, memory, disk I/O, and network throughput.
CIS benchmark implementation, SELinux/AppArmor mandatory access controls, iptables/nftables firewall configuration, fail2ban intrusion prevention, SSH hardening, audit logging with auditd, and compliance-ready configurations for HIPAA and CMMC.
Docker containerization, Kubernetes cluster deployment and management, Helm chart development, container image security scanning, registry management, and production orchestration with monitoring and auto-scaling.
Linux workloads on AWS (EC2, ECS, EKS), Azure (VMs, AKS), and GCP (GCE, GKE) with automated provisioning, auto-scaling groups, and cost optimization. On-premises virtualization with Proxmox VE, KVM, and LXC containers.
PostgreSQL, MySQL/MariaDB, MongoDB, and Redis on Linux platforms. Replication configuration, backup automation, performance tuning, query optimization, and high-availability setups with streaming replication and connection pooling.
Infrastructure-as-code with Ansible, Terraform, and NixOS declarative configuration. CI/CD pipeline integration with GitHub Actions, GitLab CI, and Jenkins. Automated patching, configuration management, and compliance enforcement.
Yes. Most business environments are heterogeneous. We manage Linux servers alongside Windows infrastructure, Active Directory integration, file sharing between platforms, and unified monitoring. Our managed IT services cover both ecosystems.
Yes. We configure GPU-accelerated Linux environments for AI/ML training and inference, including NVIDIA CUDA/cuDNN setup, PyTorch/TensorFlow optimization, and container-based model serving. See our AI services for more details.
Absolutely. We implement CIS benchmarks, configure mandatory access controls, deploy audit logging, encrypt data at rest and in transit, and document all controls for compliance evidence. Linux security hardening is one of our core strengths.
We provide emergency break-fix support for Linux systems. Whether it is a crashed server, a failed RAID array, a kernel panic, or a compromised system, our engineers can diagnose and resolve Linux emergencies quickly.
