Google 的 Load balancer:Seesaw

前幾天因為流感而睡太多,來消化一些文章。

上個星期 Google 放出一套用 Go 寫的 Load balancer,叫 Seesaw:「Seesaw: scalable and robust load balancing」。

比較有趣的是 BGP 與 anycast VIP 的能力:

Seesaw v2 provides full support for anycast VIPs - that is, it will advertise an anycast VIP when it becomes available and will withdraw the anycast VIP if it becomes unavailable.

Google 這個規模玩的是不同 scale 的花樣...
