Engineering Scope & Deliverables

Concrete administration, tuning, and incident resolution capabilities for this environment.

Resource Tuning

Virtual Resource Sizing & Memory Caps

Configuring swap files, memory swappiness, and PHP-FPM process limits specifically tuned for constrained VPS memory envelopes.

Virtualization

KVM, OpenVZ & Cloud Hypervisor Guest Optimization

Installing QEMU guest agents, optimizing virtio disk and network drivers, and configuring Cloud-Init provisioning.

Storage

Disk I/O & Storage Expansion

Resizing LVM volumes and expanding root partitions dynamically following provider VPS disk upgrades.

Stack Setup

Web Stack & Database Optimization

Lightweight Nginx and MariaDB tuning designed to prevent OOM killer events on VPS instances from 1GB to 32GB RAM.

Engineering FAQ

Frequently Asked Questions

Clear answers about operational models, access security, and engineering scope.

01 Which VPS providers do you support?

We support VPS instances across DigitalOcean, Linode / Akamai, Vultr, Hetzner Cloud, OVHcloud, Contabo, AWS Lightsail, and private KVM/OpenVZ nodes.

02 Can you prevent MySQL from crashing due to low RAM on small VPS servers?

Yes. We configure dedicated swap space, tune InnoDB buffer pool sizing, disable unused daemon modules, and cap PHP worker concurrency so the Linux OOM killer is never triggered.
