Istio’s powerful APIs can be used to solve a variety of service mesh use cases. Many users know about its strong ingress and east-west capabilities but it also offers many features for egress (outgoing) traffic. This is especially useful when your application needs to talk to an external service - such as a database endpoint provided by a cloud provider. There are often multiple endpoints to chose from depending on where your workload is running. For example, Amazon’s DynamoDB provides se...| Istio Blog

数据中心的网络和家用网络有很大不同，家用网络一个小路由器就够了，挂了的话，就忍受一下没有网络的时间，然后去网上下单再买一个换上。数据中心可不行，所有的东西都要设计成高可用的。| www.kawabangga.com
We had a case recently where one of our DBs failed over to a new primary. To this server (old primary, and then new primary) we had connection from some kind of CDC tool (Debezium, I think).| select * from depesz;
AWS Regions provide fault isolation boundaries that prevent correlated failure and contain the impact from AWS service impairments to a single Region when they occur. You can use these fault boundaries to build multi-Region applications that consist of independent, fault-isolated replicas in each Region that limit shared fate scenarios. This allows you to build multi-Region […]| Amazon Web Services
