What load balancing platforms work best for a SaaS company distributing traffic across cloud infrastructure without adding unnecessary complexity to the stack? I've been looking into this specifically from a SaaS angle; the tradeoffs look different when you're on shared cloud infrastructure and every layer you add is another thing to maintain. Sharing what I found going through SaaS-focused reviews; curious whether others have landed on something different.
- AWS Elastic Load Balancing: most common starting point for AWS-native SaaS teams; path-based routing, Auto Scaling integration, and graceful draining built in
- Cloudflare Application Security and Performance: handles traffic distribution and security in one layer; not a pure load balancer but SaaS teams in the reviews found the consolidation worth it
- Traefik: standout for containerized SaaS stacks; dynamic service discovery means new services come online without manual config changes
- HAProxy: shows up for teams that want fine-grained routing without cloud vendor lock-in; reviewers described it as infrastructure that you can deploy and forget about
- Fastly Content Delivery: CDN-first but used by SaaS teams to offload origin load during spikes; near-instant cache invalidation was the practical differentiator
If your SaaS stack is already on one cloud provider, has the native load balancer been enough on its own, or has something else always ended up in front of it?

Been researching load balancing options and one question I want the community’s opinion on is: Which load balancing software maintains session consistency even during planned server maintenance windows without routing users into broken states. The reviews cover this pretty unevenly, so wanted to pull together what's out there. Sharing what I found and curious if others have experience with this.
Here's what I've been comparing:
- HAProxy came up the most here. Zero-downtime reloads let it route traffic away from a server before it restarts, and session affinity holds through that process.
- Progress Kemp LoadMaster got called out for the monitoring dashboard being genuinely useful during maintenance windows, and for conditional routing rules that keep sessions pinned to a specific backend during a drain.
- Load Balancer Enterprise ADC has granular session persistence controls, including cookie and IP-based affinity, and supports high-availability pairs for seamless handoff when a backend enters maintenance.
- Cloudflare Application Security and Performance routes traffic at the edge and redirects away from a backend automatically when health checks fail. Reviews mentioned it for planned maintenance because the routing change takes effect without touching origin config.
- F5 NGINX supports weighted routing, so you can gradually move traffic away from a backend before taking it down rather than cutting over all at once. Reviews described it as reliable in environments where multiple services share infrastructure and maintenance needs to be coordinated across them.
Has anyone found a meaningful difference in how long different tools take to drain active sessions before a backend is safe to restart? Curious whether any of these have a built-in way to prevent new sessions from hitting a server that's about to enter maintenance, without requiring a manual configuration change every time.
