美国主机商DigitalOcean近期宣布旗下的负载均衡器产品完成了重大升级,现可轻松处理每秒高达一百万次请求或同时连接。用户通过使用最新的DigitalOcean负载均衡器,能够更灵活地运行和扩展应用程序。
负载均衡器,英文名称为Load Balancer,它可以将服务器单位时间内访问量分摊到多个操作单元上执行,即分配流量,能有效提高服务器的可用性和响应速度,带给用户更好的体验。
DigitalOcean负载均衡器本次升级后,用户可以通过添加或删除适当数量的节点(有1~100个)来确定负载均衡器处理的流量大小。单个节点支持增加负载均衡器的最大容量,如下所示:
- 每秒10000个请求或RPS
- 10000个同时连接
- 每秒250个新的SSL连接
DigitalOcean负载均衡器的定价是基于其大小,并由分配给它的节点数量决定,本身不会产生带宽费用。目前每个节点每月花费是10美元,比如要创建带有5个节点的负载均衡器,那么每月价格将是50美元。现有的负载均衡器升级为新版本后,不会损失性能,并保持相同的价格。
