NGINX Plus
NGINX Plus provides modern on-premise load balancing at $2,500-5,500/year per instance. Strong API gateway features, dynamic configuration, and excellent documentation. Better suited for modern app architectures than legacy systems. Requires VM deployment without hardware appliance option. Best for companies modernizing datacenters with microservices, API-heavy applications, or hybrid cloud strategies requiring consistent tooling.

AWS Elastic Load Balancing (ALB/NLB)
AWS ALB/NLB is cloud-only and not suitable for on-premise deployments. While AWS offers Outposts for on-premises AWS infrastructure, it requires significant investment and AWS commitment. Not recommended for traditional on-premise load balancing needs—consider F5, Kemp, HAProxy, or NGINX instead for datacenter deployments.

Frequently Asked Questions
01 Should I buy hardware appliances or virtual editions?
Hardware appliances offer higher throughput, dedicated resources, and simpler licensing but require upfront capital expenditure and longer refresh cycles. Virtual editions provide deployment flexibility, easier scaling, and lower entry costs but consume VM resources and may require per-socket licensing. Choose hardware for performance-critical production workloads; choose virtual for development, testing, or environments already virtualized.
02 What's the total cost of ownership for on-premise load balancers?
TCO includes: initial license ($2,000-50,000), annual support (15-22% for perpetual or full subscription cost), hardware/VM infrastructure, professional services ($5,000-25,000 setup), training, high availability duplicate licensing, and operational overhead. Factor in 3-5 year refresh cycles. Virtual editions reduce hardware costs but increase VM licensing. Calculate TCO over 5 years for accurate comparisons.
03 How do I achieve high availability on-premise?
HA requires two load balancer instances (active-passive or active-active), matching licenses for both, shared storage or state synchronization, and network configuration for failover. Most vendors (F5, Kemp, HAProxy, NGINX) support HA natively. Expect to double licensing costs and plan for sub-second failover. Test failover scenarios regularly and ensure monitoring detects failures automatically.
04 What security features are essential for on-premise deployments?
Essential features include: SSL/TLS offloading and termination, Web Application Firewall (WAF) for OWASP protection, DDoS mitigation, rate limiting, authentication integration (LDAP/AD/SAML), certificate management, and comprehensive logging for SIEM integration. F5 and Kemp include WAF in higher tiers. HAProxy and NGINX require WAF add-ons ($2,000+/year for NGINX WAF).
05 Can I migrate from on-premise to cloud load balancers later?
Migration complexity varies by product. NGINX Plus and HAProxy configurations are mostly portable between on-premise and cloud. F5 BIG-IP and Kemp require significant reconfiguration when moving to AWS ALB or cloud-native alternatives. For hybrid strategies, choose NGINX or HAProxy with consistent tooling. For cloud-first futures, evaluate if on-premise investment makes sense versus starting cloud-native.
06 What is the average cost of load balancers?
Pricing varies significantly based on features and scale. Entry-level plans typically start at $16/month, while enterprise solutions can cost $50000+ per month. Most organizations spend between $32-$15000/month depending on their size and requirements.
07 What hidden costs should I watch for?
Common hidden costs include implementation and onboarding fees, training expenses, premium support tiers, API access charges, storage or usage overages, per-user fees beyond base limits, and integration costs with existing systems. Always request total cost of ownership estimates for year one and beyond.
08 Do I need specialized features or will standard plans work?
Most organizations find mid-tier plans sufficient initially. Consider premium tiers only if you need advanced compliance, dedicated support, complex integrations, or specific capabilities not available in standard offerings. Start with a pilot to validate requirements before committing to enterprise contracts.
