Array APV vs Linux Virtual Server

Array APV is an application delivery controller series for managing application availability, scalability, performance, security, and traffic. It balances server traffic across Layers 2, 3, 4, and 7, with health checks, persistence, clustering, and failover. Administrators can configure Layer 7 policies in the WebUI or CLI and combine them for customized traffic management. APV includes SSL/TLS acceleration and offloading, connection multiplexing, caching, and compression, along with certificate and key management. The x850 datasheet describes WebWall web application security and DDoS protection. Listed integrations include OpenStack Load Balancing-as-a-Service, VMware Cloud Orchestrator, and Microsoft System Center standards. Deployment options include physical or virtual appliances, hyper-converged infrastructure, and cloud platforms; vAPV documentation names VMware ESXi, Hyper-V, KVM, Citrix XenServer, Nutanix, AWS, Azure, and Google Cloud Platform. Management options include secure CLI, WebUI, SSH remote management, role-based administration, and real-time monitoring. Array identifies banking, healthcare, manufacturing, government, education, and service providers among the sectors it serves. Pricing is on request.

Linux Virtual Server (LVS) turns a cluster of real Linux servers into one virtual server for users. Its IPVS component performs layer 4 balancing in the Linux kernel, directing TCP and UDP requests sent to a virtual service IP toward servers behind it. Supported forwarding methods are NAT, FULLNAT, tunneling, and direct routing. The project lists web, cache, mail, FTP, media, and VoIP services as applications. Capacity can be changed by adding or removing cluster nodes. Failure detection can identify node or daemon problems and reconfigure the system for availability. Keepalived checks server-pool state at layers 3, 4, and 5 and tells the kernel to remove a failed server. KTCPVS supplies application-level balancing but is under development. LVS is free GPL-licensed software for Linux and self-hosted use. Administration uses ipvsadm, with documentation for configurations, scheduling, high availability, and DoS defense.
