Performance and Scale

Introduction:

Authentication is the front door to your systems. Any latency, lag, or downtime at this critical step directly translates to lost users, frustrated customers, and lost revenue. An identity solution cannot be an afterthought; it must be a high-throughput, low-latency component capable of handling internet-scale traffic.

GoAM was architected from the ground up for speed. The deliberate choice of Go and the fasthttp library ensures minimal resource consumption, high concurrency, and incredibly fast response times. This makes it suitable for the most demanding workloads, from login "flash crowds" during a marketing campaign to high-volume API authentication.

Compared to traditional IAMs GoAM has a very small footprint of only around 50MB memory consumption. Our architecture with FastHTTP enable thousands of request per second with sub <5ms. GoAM is horizontally scalable, the only bottleneck is the database. Per default we use Postgres which is good enough for most. If we need to go really big, like milllions of parallel request and users we can use Cockroach Db or Google Cloud Spanner. If you have your own database already in place we can integrate with it using a custom DB adapter.

Use Case Example

A large-scale mobile gaming company can use GoAM to handle the massive, sudden spike of logins that occurs when a new game is launched or a major event starts. The system's ability to handle thousands of concurrent requests per second ensures a smooth login experience for all players.

A B2B SaaS provider can leverage GoAM's multitenancy to serve hundreds of different customer organizations from a single, scalable deployment. Each customer (tenant) has its own isolated configuration, userbase, and authentication flows, all while sharing the same underlying high-performance engine, making management efficient and cost-effective.
