Geode 网络配置最佳实践

介绍

Geode is a data management platform that provides real-time, consistent access to data-intensive applications throughout widely distributed cloud architectures. Geode pools memory是一个数据管理平台，提供实时的、一致的、贯穿整个云架构地访问数据关键型应用.

Geode 池化了服务器上的内存, CPU, network resources, and optionally disk storage across multiple processes to manage application objects and behavior. It uses dynamic replication and data partitioning techniques to implement high availability, improved performance, scalability, and fault tolerance. In addition to being a distributed data container, Geode is an in-memory data management system that provides reliable asynchronous event notifications and guaranteed message delivery.

Due to Geode’s distributed nature, network resources can have a significant impact on system performance and availability. Geode is designed to be fault tolerant and to handle network disruptions gracefully. However, proper network design and tuning are essential to achieving optimum performance and High Availability with Geode.

网络资源, 和本地磁盘，跨多个进程来管理应用对象和应用行为. 它使用了动态数据复制和分区技术来实现高可用, 高性能, 高可扩展性, 和容错. 另外, 对于一个分布式数据容器, Apache Geode 是一个基于内存的数据管理系统, 提供了可靠的异步事件通知和可靠的消息投递.

由于 Geode天生的分布式特性, 网络资源对于系统的性能和可用性有比较大的影响. Geode 被设计具有容错能力和自动处理网络中断故障. 然而, 合适的网络设计和调优对于达到最佳性能是必要的.

目的

本篇文章主要提供配置网络资源的最佳实践. 本推荐并不提供很详细的网络设计和实现指南. 然而, 是提供一个工作基础, 指导大家进行网络配置实现The purpose of this paper is to provide best practice recommendations for configuring the network resources in a Geode solution. The recommendations in this paper are not intended to provide a comprehensive, one-size-fits-all guide to network design and implementation. However, they should serve to provide a working foundation to help guide Geode implementations.

Geode: 快速回顾

概要介绍

A Geode distributed system is comprised of members distributed over a network to provide in-memory speed along with high availability, scalability, and fault tolerance. Each member consists of a Java virtual machine (JVM) that hosts data and/or compute logic and is connected to other Geode members over a network. Members hosting data maintain a cache consisting of one or more Regions that can be replicated or partitioned across the distributed system. Compute logic is deployed to members as needed by adding the appropriate Java JAR files to the member’s class path一个 Geode 分布式系统由跨网络的成员节点组成, 提供内存速度, 带有高可靠, 高扩展性, 和容错. 每个成员基于JVM, 管理数据和计算逻辑, 连接到其他 Geode 成员. 管理数据的成员维护一个缓存, 缓存中的Region 可以跨分布式系统进行复制或分区. 计算逻辑被部署到添加合适 Java JAR 文件的成员上.

使用 Geode 的公司:

• 减少风险分析从6 小时到 20 分钟, 在闪电崩盘的过程中能够记录下交易资料, 而其他机构都不能够做到这一点.
• 增强的最终用户响应时间, 从3秒到 50 毫秒, 一年能够增加 8 位数的收益, 而项目交付小于6个月.
• 实时追踪资产, 协调对的人和机器在对的时间到达对的地点, 发挥高价值的机会.
• 创建用户预留系统, 每天可以处理10亿的请求
• Reduced risk analysis time from 6 hours to 20 minutes, allowing for record profits in the flash crash of 2008 that other firms were not able to monetize.
• Improved end-user response time from 3 seconds to 50 ms, worth 8 figures a year in new revenue from a project delivered in fewer than 6 months.
• Tracked assets in real time to coordinate all the right persons and machinery into the right place at the right time to take advantage of immediate high-value opportunities.
• Created end-user reservation systems that handle over a billion requests daily with no downtime.

Geode 通信

Geode 成员使用 TCP, UDP 单播和 UDP 多播相结合的方式进行成员之间的通信. Geode 成员与其他成员之间维护着经常性通信 , 为了分发数据和管理整个分布式系统.
