LINUX VIRTUAL SERVER LOAD BALANCER VS ARRAY NETWORKS ADC

COMPARISON AMONG LINUX VIRTUAL SERVER LOAD BALANCER, ARRAY NETWORKS ADC AND RELIANOID LOAD BALANCER

What is Array Networks APV Series

The Array Networks APV Series is a high-performance Application Delivery Controller (ADC) family available as physical, virtual, and cloud appliances that accelerate, secure and ensure availability of applications across data center and cloud environments. At its core, APV provides Layer-4 to Layer-7 load balancing and intelligent traffic management to keep applications fast and available by directing user requests according to dynamic and policy-based decisions. Array’s APV appliances include SSL/TLS acceleration and interception, connection multiplexing, caching and compression, traffic shaping, DDoS protections, Global Server Load Balancing (GSLB), and an integrated Web Application Firewall (WAF).
Array Networks

Built on Array’s SpeedCore® 64-bit architecture and a kernel-level L7 policy engine, APV delivers efficient processing and low-latency traffic handling suitable for enterprises, service providers and public sector deployments. APV also provides automation and orchestration through REST/XML-RPC and integrations with cloud/virtual platforms, making it flexible for modern CI/CD and cloud-native workflows.

What is LVS Load Balancer

A Linux Virtual Server (LVS) Load Balancer is a powerful and scalable solution built to efficiently manage and distribute network traffic across multiple backend systems. Integrated into the Linux kernel through the IP Virtual Server (IPVS) module, LVS functions at the transport layer, primarily handling TCP and UDP traffic. It balances incoming requests among several servers to improve application availability and system scalability, ensuring no individual server is overloaded. LVS supports multiple operation modes—such as NAT (Network Address Translation), DR (Direct Routing), and TUN (IP Tunneling)—offering flexible options for how traffic is managed and routed.

This type of load balancer is especially suitable for high-demand environments like large-scale websites, database clusters, or performance-intensive services. Its capacity to handle millions of concurrent connections makes it a reliable choice for enterprise infrastructures and data centers. Furthermore, LVS can be paired with high-availability tools such as Keepalived or Heartbeat to deliver redundancy and enable automatic failover in the event of hardware or software failures, guaranteeing service continuity. Its native compatibility with the Linux ecosystem empowers administrators to utilize open-source utilities while avoiding the expenses of commercial load balancing platforms.

WHAT IS RELIANOID

RELIANOID as alternative to LVS Load Balancer and Array Networks ADC across key ADC capabilities

RELIANOID bridges the gap between the basic, manual nature of Linux Virtual Server (LVS) Load Balancer and the restricted scalability of Array Networks ADC. While Array provides affordable, practical ADC capabilities and LVS offers highly efficient kernel-level load balancing but requires deep expertise, lacks modern ADC features, and involves manual maintenance, RELIANOID combines high-performance load balancing, advanced security, and simplified operations in a lightweight, cost-efficient, and platform-agnostic solution. It supports modern protocols like HTTP/2, features hot-reload for zero-downtime updates, and integrates seamlessly with containerized, cloud, and hybrid infrastructures. For organizations needing enterprise-ready ADC features without the operational burden of managing LVS manually, RELIANOID is the smart choice.
