Load Balancing Performance Security HAProxy ALOHA Hardware HAProxy ALOHA Virtual Administration

Intelligent and flexible traffic management

Power your applications and APIs regardless of demand, deployment model, or underlying tech stack.

Multiple load balancing modes

Load balance Layer 4 (networking) or Layer 7 (application layer) traffic — with support for reverse proxy, transparent proxy, direct server return, NAT, IPIP, and VIP-less modes.

Global Server Load Balancing (GSLB)

HAProxy ALOHA can act as an authoritative DNS server across global regions and assign client requests to local datacenters. Unlock failover and round-robin traffic distribution.

High availability

Keep your applications and APIs online via advanced health checks, backup server support, traffic overload protection, support for VRRP floating virtual IPs, and route health injection.

Broad protocol support

Load balance HTTP, HTTP/2, HTTP/3, HTTP/3 over QUIC, UDP, gRPC, FastCGI, Financial Information eXchange (FIX), and MQTT traffic — and more.

Low-latency performance tuned for you

Built from the ground up for efficient performance, HAProxy ALOHA grants you the speed you need — with room to scale seamlessly.

Compression

Compress HTTP responses before passing them to clients. Reduce payload sizes, bandwidth usage, and server CPU load.

Connection management

Release unused connections early, dynamically control server-side connections for improved resource usage, and filter malformed TCP connections or HTTP requests.

Buffering and queueing

Accelerate TCP and HTTP performance by intelligently managing data flows between devices, while giving the recipient more time to process data without becoming overwhelmed.

HTTP header manipulation

Alter any specific HTTP header within each request or response to use caching more effectively, reduce data payloads, and employ mechanisms such as Keep-Alive.

Tackle common and emerging threats with next-gen security

HAProxy ALOHA includes a host of powerful security features to keep your applications, users, and data safe.

HAProxy Enterprise WAF

Powered by our Intelligent WAF Engine using threat intelligence data from HAProxy Edge, HAProxy Enterprise WAF delivers a balanced accuracy of 98.48% with ultra-low latency to counteract evolving threats.

HAProxy Enterprise Bot Management Module

Identify, categorize, and filter harmful bots and crawlers attempting to access your applications. Stop DDoS attacks, fraud, scraping, brute force attacks, and more — without blocking legitimate bots or web tools.

Robust encryption

End-to-end TLS encryption for all communication ensures the highest levels of data security and privacy. TLS termination speeds up decryption at the load balancer while minimizing added latency.

PacketShield filtering

Our patented DDoS protection filters incoming packets at a wire-speed line rate, and blocks unwanted traffic in real-time with zero false positives. Deploy as a router or load balancer.

Powerful, rack-mounted devices

Support performance-sensitive applications and APIs, with the option to scale when you need it.

Two high-performance models

Whether you're a small business or large enterprise, HAProxy ALOHA load-balancing models are tuned for your unique needs. Choose between two rack-mounted 1U devices and operational modes for optimal performance.

Flexible licensing

HAProxy ALOHA offers multiple licensing options with unique performance and capacity specs — and gives your organization room to grow if infrastructure needs change. Change your setup later without expensive device upgrades.

Diverse network interface support

Equip your hardware load balancers with SFP+ and QSFP+ optical transceivers to interconnect them with your core network. Choose the network the bandwidth you need (1, 10, or 40 Gbps) by aggregating links and establishing combinations of network interfaces.

PacketShield filtering

Our patented DDoS protection filters incoming packets at a line rate up to 10 Gbps (at wire speed), and blocks unwanted traffic in real-time with zero false positives. Deploy as a router or load balancer.

Built for your virtualized infrastructure

Delivering the same powerful Layer 7 and Layer 4 features as HAProxy ALOHA Hardware appliance — packaged specifically for leading hypervisors.

Seamless integration

Deployable as a virtual image, HAProxy ALOHA Virtual Load Balancer ships with support for VMWare, Microsoft Hyper-V, and KVM (Kernel-based Virtual Machine) hypervisors.

Native management

Harness an embedded GUI to manage configuration, monitor real-time performance, security, health, connection details, and more. Use the Network Management API to control your multi-tenant architecture.

Flexible network architecture

Aggregate and create VLAN in a snap, while fully controlling how the network is presented to the underlying VM. Establish and simulate complex networking environments without paying for expensive, supplemental equipment.

Everything, on one machine

Test how your networking setup reacts to changing traffic conditions, failover events, and dynamic packet flows. Manage multiple GSLB-enabled DNS zones, while running the client and DNS servers all on your PC.

Take control of your infrastructure

HAProxy ALOHA ships with a host of GUI and API-driven management tools to keep your infrastructure running smoothly.

Standards-based administration

Take advantage of support for SNMP, NTP, Syslog, and VRRP to keep your load-balancing setup synchronized, manageable, and reliable.

Interfaces for any preference

Manage configuration, provisioning, monitoring, and diagnostics via web-based interface or the Network Administration API. Connect directly via serial port or remotely via SSH.

Configuration templating

Deploy your applications in minutes without having to write complex configuration sections from scratch. Quickly configure network interfaces, link aggregation, VLAN membership, IP-related parameters, and more.

VLAN tagging

Identify and isolate traffic by assigning unique VLANs to groups of devices and their ethernet frames. Clearly track your network packets and control traffic flows, while boosting performance and security.

What are users saying about HAProxy ALOHA?

"I enjoy having an interface without extra frills or anything fancy. It makes it simple to input your config, easy to check the status of your applications, and quick to deploy. When you have questions or need configuration assistance, the ALOHA team does an excellent job in helping."
