VPS Hosting with Sentora

Sentora on KVM VPS: Zero Licensing Cost, Full Root Control

Sentora VPS Hosting with AvaHost pairs a free, open-source control panel with KVM-virtualised infrastructure hosted in Moldova. Each plan allocates dedicated vCPU cores, RAM, and NVMe storage — resources not shared with neighbouring tenants — giving administrators predictable headroom for web applications, mail services, and database workloads. Plans start at €5.00/mo and scale to €40.00/mo; full specifications are available in the plan selector above.

Sentora is a community-maintained, Apache-licensed control panel for Linux. Because it carries no per-seat or per-server licence fee, operators running multi-tenant or reseller environments avoid the recurring costs associated with commercial panels such as cPanel or Plesk. The panel exposes domain management, DNS zone editing, MySQL provisioning, FTP account creation, email configuration, and cron scheduling through a browser interface — without requiring shell interaction for routine tasks. Full root SSH access is included on every AvaHost VPS Hosting plan.

Sentora is compatible with Ubuntu and CentOS. AvaHost's support team is available 24/7 and can assist with initial panel installation. DDoS protection is active at the network layer on all plans, and each VPS receives a dedicated IPv4 address.

Open-Source Architecture and the Operational Case for Zero Licensing Overhead

Commercial control panels introduce a recurring cost that scales with managed accounts or server instances. Sentora eliminates that variable entirely. For a reseller provisioning ten client accounts, or an agency managing staging and production environments across multiple VPS nodes, the absence of per-licence fees directly reduces monthly operational expenditure without any reduction in panel capability.

Sentora's codebase is intentionally lightweight. The panel daemon and web front-end consume a fraction of the CPU and RAM that heavier commercial panels require at idle, meaning a greater proportion of provisioned resources remains available to application processes. On an entry-level plan with 2 GB RAM, a panel consuming 80–120 MB at idle leaves materially more headroom for PHP-FPM worker pools or MySQL buffer pools than one consuming 300–400 MB.

• Zero licence costNo per-account, per-server, or annual renewal fee — reduces TCO for multi-site and reseller deployments.
• Low idle resource footprintPanel overhead is minimal, preserving allocated vCPU and RAM for application workloads rather than management processes.
• Community-driven module ecosystemBilling integrations, monitoring extensions, and DNS utilities are available as installable modules, allowing operators to extend functionality without migrating to a different stack.
• Open-source auditabilityThe codebase is publicly available; security-conscious teams can audit panel behaviour, review update diffs, and apply patches without waiting on a vendor release cycle.

Business outcome: Eliminating panel licensing from the cost model is particularly relevant for agencies and resellers billing clients at fixed monthly rates. The saving compounds across each additional managed server, improving margin without requiring a change in service delivery.

KVM Isolation, NVMe Storage, and Workload Predictability Under Production Load

AvaHost's VPS infrastructure uses KVM (Kernel-based Virtual Machine) virtualisation, which provides hardware-level isolation between virtual machines. Each instance runs its own kernel, and CPU scheduling, memory allocation, and I/O queues are separated at the hypervisor level. A CPU-intensive workload on a neighbouring VM does not introduce steal time into your instance — a common cause of latency spikes on older paravirtualised or container-based products.

All plans use NVMe storage. NVMe's direct PCIe attachment removes the protocol translation overhead present in SATA-attached SSDs, reducing fsync latency and improving sequential throughput. For Sentora-managed workloads — particularly MySQL databases serving dynamic CMS installations — lower fsync latency translates directly to faster query commit times and reduced I/O wait under concurrent request loads.

• KVM hypervisor isolationDedicated CPU and RAM allocation per instance; no resource contention from co-tenants at the hypervisor scheduler level.
• NVMe storage across all plansConsistent low-latency I/O from entry to top tier; no plan-tier downgrade to SATA SSD.
• Dedicated IPv4 per instanceA prerequisite for valid SSL certificate issuance and avoids shared-IP reputation issues affecting email deliverability.
• DDoS protection at network layerActive on all plans; absorbs volumetric attacks before they reach the instance without requiring customer-side configuration.

Business outcome: Predictable I/O and CPU performance under sustained load reduces the risk of unplanned scaling events. Teams can right-size their plan against benchmarked workload data rather than provisioning excess capacity as a buffer against noisy-neighbour variance.

Sentora's Administrative Feature Set: Domain, Mail, and Database Management Without Shell Dependency

Sentora's web interface covers the operational surface area that most hosting administrators interact with daily. DNS zone management, MX record configuration, MySQL database and user provisioning, FTP account creation, and subdomain routing are all handled through the panel GUI. Operators who delegate hosting management to non-technical staff benefit from a reduced skill threshold for day-to-day operations, without losing root SSH access for those who need it.

The panel's cron scheduler allows automated task execution at defined intervals, relevant for CMS maintenance scripts, database export routines, and log rotation jobs. Multi-user and reseller account structures are supported natively: an administrator can create isolated client accounts with defined resource allocations, making Sentora a practical choice for agencies hosting client sites on a single VPS or across a small fleet.

For operators whose workloads eventually exceed VPS capacity, AvaHost's Dedicated Servers provide bare-metal resource allocation. Teams migrating from a Sentora-managed VPS can retain the same panel on a dedicated instance, preserving configuration and operational workflows during the transition.

Compatibility, Upgrade Paths, and Infrastructure Fit for Growing Deployments

Sentora supports Ubuntu and CentOS, covering the two most widely deployed Linux distributions in production hosting environments. Operators can select the distribution that aligns with existing configuration management tooling, whether Ansible playbooks written against Ubuntu's package conventions or CentOS-based RPM workflows.

For teams on shared hosting encountering resource ceilings — PHP memory limits, restricted cron scheduling, or the absence of root access — migrating to a Sentora-managed VPS resolves all three constraints in a single step. Shared Web Hosting suits low-traffic sites, but once requirements demand custom software installation, persistent background processes, or isolated database performance, a KVM VPS with Sentora provides the necessary control layer.

Payments are accepted via Visa, Mastercard, PayPal, bank transfer, WebMoney, and over 20 cryptocurrencies including BTC, ETH, and USDT. All prices are denominated in EUR; billing period is selected at checkout. AvaHost has operated as a hosting provider since 2002.

The plan selector above lists full specifications and pricing for each VPS tier. Entry-level deployments running a single CMS installation with moderate traffic are well served by the lowest tier; reseller environments or multi-site agencies should evaluate higher tiers, where additional vCPU and RAM headroom support parallel PHP-FPM pools and MySQL instances without resource contention between accounts.
