Inside The Fusion Arc Hosting Platform

Your website doesn't run on one technology. It runs on an ecosystem.

From the moment a request reaches our network to the moment your website responds, multiple layers of compute, security, isolation, caching, storage, database technology and backup infrastructure are already working behind the scenes. Fusion Arc Hosting combines enterprise hosting technologies into one tightly integrated platform engineered for speed, resilience and control.

Follow A Request

A lot happens before your visitor ever sees a page.

A website request can move through network routing, security inspection, account isolation, LiteSpeed processing, PHP execution, database queries, caching and storage before a response is returned. Our stack is built so those systems cooperate instead of becoming a collection of disconnected add-ons.

REQUEST PIPELINE

Integrated by design.

Security, compute and application delivery are more effective when they operate together. Your hosting environment is built around that principle from the network upward.

Security inspection ACTIVE
Account isolation ENFORCED
Application delivery READY
Imunify360 Security Layer

Every request shouldn't automatically be trusted.

Your website is exposed to the public internet, and the public internet has never been famous for restraint. Imunify360 adds multiple security layers around your hosting account so suspicious behavior can be analyzed before it becomes your problem.

01
Traffic Reputation Incoming activity can be evaluated before access is granted.
02
Web Application Firewall Malicious request patterns can be challenged or blocked.
03
Malware Detection Files and account activity can be inspected for malicious code.
04
Brute Force Protection Repeated hostile authentication attempts can be identified and stopped.

CloudLinux LVE + CageFS

Your neighbor shouldn't get to eat your server.

Traditional shared hosting can allow one demanding account to consume disproportionate resources. CloudLinux changes that model by placing hosting accounts into controlled resource environments.

CPU resources can be governed per hosting account.
Memory limits help prevent one application from overwhelming the server.
Disk I/O and entry processes can be controlled independently.
CageFS creates a private virtualized filesystem view for each account.
Resource isolation helps preserve stability when another customer experiences a traffic or application spike.
Compute Architecture

Hosting performance starts underneath the control panel.

Our infrastructure uses modern AMD Ryzen, AMD EPYC and enterprise Intel Xeon compute platforms across the Fusion Arc Hosting fleet. CloudLinux then divides that physical compute into controlled hosting environments so resources can be allocated where customers actually need them.

RYZEN

High-frequency compute

Excellent single-thread performance helps dynamic websites, PHP applications, WordPress workloads and control-panel operations respond quickly.

Layered Traffic Defense

The goal isn't to block traffic. It's to block the wrong traffic.

Legitimate visitors need a clear path to your application while abusive or malicious traffic should encounter multiple defensive controls. Fusion Arc Hosting combines network protections with server and application-layer defenses rather than relying on one security mechanism.

Storage + Data Protection

Fast storage is useful. Redundant, recoverable storage is better.

Our hosting architecture combines SSD and NVMe storage with RAID configurations across applicable systems and separate offsite backup infrastructure. Because pretending one copy of important data is a disaster-recovery strategy would be adorable.

HIGH SPEED

SSD + NVMe Storage

Fast solid-state storage helps reduce application wait time, database latency and filesystem operations for modern websites.

REDUNDANCY

RAID Architecture

RAID 1 and RAID 10 configurations are used across applicable infrastructure to provide disk-level redundancy alongside the broader backup strategy.

OFFSITE

JetBackup Protection

JetBackup powers automated backup workflows with backup data sent to separate offsite object storage rather than existing only beside the live website.

Network + Datacenter Infrastructure

Your hosting account is the visible part. The network underneath it is considerably larger.

Fusion Arc Hosting operates infrastructure across U.S. datacenter partner environments with high-capacity connectivity, routing, server infrastructure and redundant systems working together to move traffic between visitors and hosted services.

Hosting Platform

Enterprise technology without requiring you to become a systems administrator.

Powerful infrastructure matters most when customers can actually use it. The hosting platform combines cPanel management, application installers, developer runtimes, web acceleration and automated security into a familiar interface.

CONTROL.01

cPanel + WHM

Manage websites, domains, DNS, databases, email accounts, files, SSL certificates and hosting features through the industry-standard cPanel ecosystem.

WEB.02

LiteSpeed Enterprise

High-performance web serving built for modern PHP applications, HTTP/2, HTTP/3 and efficient concurrent request processing.

CACHE.03

LiteSpeed Cache

Server-integrated caching technology can dramatically reduce the amount of work required to produce frequently requested pages.

APPS.04

Softaculous

Deploy WordPress, Joomla, Drupal, forums, ecommerce applications and many additional software packages through simplified installers.

RUNTIME.05

PHP + LSAPI

Modern PHP environments integrate with LiteSpeed LSAPI for efficient execution of WordPress, ecommerce, CMS and custom PHP applications.

DEV.06

Node.js + Python

CloudLinux application selectors expand the platform beyond traditional PHP hosting with modern Node.js and Python runtime options.

DNS.07

PowerDNS

DNS infrastructure provides the translation layer that connects domain names with the services operating behind them.

PATCH.08

KernelCare

KernelCare helps apply important Linux kernel security updates without relying exclusively on disruptive traditional reboot cycles.

Email Protection

Your website isn't the only service attackers can abuse.

Email reputation and account security matter too. Our hosting environment incorporates outbound mail controls and ImunifyEmail technology to help identify potentially abusive sending patterns and protect the health of the larger mail platform.

Outbound sending controls help contain compromised or abusive accounts.
ImunifyEmail adds another layer of mail security analysis.
Account-level controls reduce the ability of one sender to impact the entire platform.
Mail infrastructure is monitored as part of the hosting environment rather than treated as an afterthought.
