Companies Using Amazon ALB

We detect Amazon ALB on 69,748 domains, of which 32,379 match to a company record. The population runs from one-person firms (47.88% have 1-10 employees) to Accenture, IBM, Samsung, Allianz, Verizon and the City of New York. What unites the large end is the type of property: investor sites, community forums, newsrooms and customer portals rather than corporate homepages.

Our August 2026 rollup reads 69,748 domains. Treat that as a floor rather than a total. We identify an Application Load Balancer by the AWSALB cookie, which is only written when target-group stickiness is enabled, and stickiness is off by default — so every ALB running without it is invisible to this measurement.

22.81% of Load Balancers & Proxies, second of twelve behind Envoy on 36.39%. We would not read the recent rise in that share as growth: Envoy's own reading halved between June and July 2026, which lifted every other member's share of the category. Holding Envoy at its June level puts ALB at 17.25%.

Within the category, Envoy (111,282 domains), Google Cloud Load Balancing (50,798), Azure Front Door (48,175) and Amazon ELB (16,312). The genuine substitutes depend on where you already run: Azure Front Door and Google Cloud Load Balancing are the equivalent managed services on the other two large clouds, while Envoy is the self-managed option.

The United States, on 16,372 of the 31,131 companies where we hold a country — 52.59%. The United Kingdom is a distant second at 2,082 (6.69%), followed by Australia and Canada.

47.88% of the 30,497 sized companies have 1-10 employees and 23.06% have 11-50. The distinguishing feature is the upper tail: 1,217 companies of 1,001-5,000 employees and 490 above 10,000 also appear, which is where the recognisable brand names come from.

The 2010s are the largest single decade at 26.84% of the 16,762 companies with a founding year. Notably, 16.58% were founded before 1960 — long-established institutions running a modern portal on cloud infrastructure.

A US-based organisation running a stateful web application — a customer portal, member area, community or investor site — usually on a dedicated subdomain, most often alongside other AWS services, and frequently behind a separate CDN.

It means the hostname returned an AWSALB or AWSALBCORS cookie. That cookie is generated by an Application Load Balancer to pin a visitor to one target in a target group, and it only appears when stickiness is configured. A detection is therefore firm evidence of an ALB, but the absence of one is not evidence against it.

It is the session-affinity cookie an Application Load Balancer sets so that repeated requests from one visitor reach the same backend target. AWSALBCORS is the same value issued with SameSite=None so it survives cross-site requests. Neither carries customer data; both are opaque, encrypted references to a target.

15.0% of our Amazon ALB detections are on a hostname other than the apex or www, against 3.5% for Nginx across the same crawl. Stickiness is enabled on applications that hold a session, and organisations usually put those on their own hostname — investor.company.com, community.company.com, careers.company.com.

Very often. Cloudflare appears on 38.75% of ALB domains and Amazon CloudFront on 24.0%. The balancer distributes traffic across targets inside the VPC; the CDN caches and shields at the edge. They solve different problems and roughly two in five of these domains use both.

Yes, and it is the only corridor in this category we consider strong enough to publish. 927 domains dropped Amazon ELB and now answer from an ALB, 917 of them within 90 days, against 131 moving the opposite way. Just 1.6% of that group still runs the older balancer anywhere, so it is a replacement rather than the two running side by side.

They are different products in the same AWS family. Amazon ALB is the layer-7 balancer that routes on HTTP content; Amazon ELB in our data is the older Classic balancer, which we identify by a different cookie. We track and count them separately, and the 927-domain corridor between them shows the direction of travel.
