Our Rankings
AWS Elastic Load Balancing (ALB/NLB)
AWS ALB/NLB offers the most cloud-native experience with fully managed service starting at $16.20/month plus usage-based LCU charges. Perfect auto-scaling, deep AWS integration with ECS/EKS, Lambda targets, and zero infrastructure management. ALB provides Layer 7 routing while NLB delivers ultra-low latency. Best for AWS-native applications prioritizing simplicity and elasticity.

- Some advanced features on higher tiers only
NGINX Plus
NGINX Plus excels for multi-cloud Kubernetes deployments at $2,500-5,500/year per instance. Dynamic reconfiguration API, native service discovery, gRPC load balancing, and JWT authentication make it ideal for microservices. Requires instance management but offers deployment freedom across AWS, Azure, GCP, and on-premises. Best for cloud-agnostic architectures.

Kemp LoadMaster
Kemp LoadMaster offers flexible cloud deployment at $1,990-15,000/year subscription or $0.29+/hour PAYG on AWS/Azure. Good feature completeness with WAF, GSLB, and API gateway included. Pay-as-you-go option suits variable workloads, but higher per-instance costs and less cloud-native architecture compared to AWS native offerings.

- User-friendly interface
- Reliable customer support
- Some advanced features on higher tiers only
F5 BIG-IP
F5 BIG-IP Virtual Edition provides enterprise-grade features at $5,000-50,000/year but carries legacy complexity unsuitable for cloud-native simplicity. Multi-cloud support exists, but architecture designed for traditional datacenter patterns. Best reserved for enterprises with specific F5 investments or security requirements that justify the cost and operational overhead.

Frequently Asked Questions
01 What makes a load balancer 'cloud-native'?
Cloud-native load balancers are fully managed, auto-scale with traffic, offer pay-as-you-go pricing, integrate natively with container orchestration (Kubernetes), support dynamic configuration APIs, and require zero infrastructure management. They emphasize Layer 7 capabilities for microservices, API-driven operations, and cloud provider integrations over traditional appliance-based architectures.
02 Should I use AWS ALB or run NGINX Plus on EC2?
Choose AWS ALB for simplest operations and AWS-native features—it's fully managed, auto-scales, and costs $16-50/month for most workloads. Choose NGINX Plus ($2,500/year) when requiring multi-cloud portability, advanced API gateway features, or specific routing capabilities beyond ALB. NGINX requires EC2 instance management but offers greater control and cloud-agnostic deployment.
03 How do cloud-native load balancers handle Kubernetes?
AWS ALB integrates via AWS Load Balancer Controller for EKS with automatic target registration. NGINX Plus and HAProxy use Kubernetes Ingress Controllers with dynamic service discovery and configuration. All support health checks, namespace routing, and declarative configuration. Choose based on cloud preference—AWS ALB for EKS simplicity, NGINX/HAProxy for multi-cluster or multi-cloud Kubernetes.
04 What's the real cost of AWS ALB beyond the $16/month base?
AWS ALB costs $16.20/month base plus LCU charges (typically $0.008/hour per LCU dimension). Real costs depend on: new connections/sec, active connections, processed bytes, and rule evaluations. Expect $30-100/month for small apps, $100-500/month for medium traffic. Add data transfer ($0.01/GB cross-AZ) and optional WAF ($5/month + $1/million requests).
05 Can I migrate between cloud-native load balancers easily?
AWS ALB creates vendor lock-in through AWS-specific integrations and configuration formats. NGINX Plus and HAProxy offer more portability with standard configurations that work across clouds. For cloud-agnostic architecture, choose NGINX Plus or HAProxy with infrastructure-as-code (Terraform). For AWS-committed deployments, ALB's tight integration outweighs portability concerns with superior operational simplicity.
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.
