如果您的应用程序将使用 Elastic Load Balancing,则您有多种负载平衡选择。 Application Load Balancer 具有许多 HTTP 和第 7 层功能。 网络负载均衡器具有更多 TCP 和第 3 层功能。 这些选项在第 6 章“域名系统和负载平衡”中有更深入的介绍。 网络负载均衡器的优势在于性能和规模。 由于在不查看内部数据包的...
MySQL,Aurora, PostgeSQL, MariaDB. 或者你只要记牢它不支持Microsoft SQLserver和Oracle就行了。 Read Replica我的理解就像一个缓存,它把你主数据库的数据备份然后让用户可以访问它,这样就能够增加RDS的performance 如果读写很猛烈,要scale还要sharding,当然你的query得比较简单,那就可以考虑DynamoDB啦。 DynamoDB,简...
Extreme performance TCP, UDP traffic Load Balancer Stickiness It is possible to implement stickiness so that thesame clinet is always redirected to the same instance behind a load balancer. This works for Classic Load Balancers & Application Load Balacners The "Cookie" used for stickiness has an...
A potentially infinitely scalable service can be constructed with a small set of primitives: an elastic load balancer and a scaling group of server instances. At Ably we used classic ELBs as a core element of the architecture of our AWS-hosted service after a study of AWS's performance and ...
Redundant array of independent disks (RAID) is an architecture that uses mirrored volumes to either increase performance through workload distribution or eliminate single points of failure. You can create RAID configurations to quickly duplicate EBS volumes. You can use any RAID configuration that your...
The AWS Network Load Balancer - Overviewdashboard provides detailed insights into a view of network utilization and performance. The dashboard provides information about the errors, health, and traffic handled by the load balancer. Use this dashboard to: ...
Typically, when customers ask for centralization, they are looking for control-plane centralization, and don’t consider the data plane until performance, cost, or reliability come into play. Appliance: This is the “bump-in-the-wire” function that sits in the network pa...
Application Load Balancer Network Load balancer Application Load Balancer: It supports path-based routing of the traffic and hence helps in enhancing the performance of the application structured as smaller services. Using an application load balancer, the traffic can be routed based on the requests ...

Network Load Balancer The Network Load Balancer offers high performance load balancing that operates at the network connection layer (level 4) and allows you to route connections to microservices based on IP protocol data. The Network Load Balancer can handle millions of requests per second while ma...
