Gopher  China  2015  Resource  Scheduling  &  Container  Technology  for  Financial  Service  动态资源管理和容器技术  在金融行业的架构探索和明天  余军  Gopher  China  2015  Gopher  China  2015  China  2015  求解之路的探索  n 他们是否解决了我们的问题?  n No   ① Mesos  采用了DRF(Dominant  Resource  Fairness)  调度机制。 YARN自带FIFO、Capacity  Scheduler和Fair  Scheduler(借鉴了 Mesos的DRF)。  ② Mes oop中Capacity  Scheduler的调度机制，将所有资源分成若干个queue，每个 queue分配一定量的资源，每个user有一定的资源使用上限。  ③ Mesos采用了Resource  Offer机制，这种调度机制面临着资源碎 片问题，即：每个节点上的资源不可能全部被分配完，剩下的一 点可能不足以让任何任务运行，这样，便产生了类似于操作系统 中的内存碎片问题。

placement of pods. This is used to spread pods across availability zones, while still respecting resource access and availability concerns. When Kubernetes runs on vSphere, the hypervisor platform also automated placement options, for both control plane and worker nodes. 2 levels of scheduling and resource management are active. ​Currently no automatic scheduling integration occurs, that is, Kubernetes affinity groups, NUMA, etc.). ​This session will explain the options to gain better performance, resource optimization and availability through tuning of vSphere, and Kubernetes configuration and labeling
