codeLet's break down the code so that the code can be stored in their own objects. For this reason, we refer to the Event Aggregator theory of martinfowler to process the code so that the objects can communicate with each other.First, let's implement the Event aggregation function. This function is divided into two parts: one is Event, the code used for Handler callback, and the other is EventAggregator used to subscribe to and publish events. The Co

In the K8S resource audit and billing this piece, the container and the virtual machine have very big difference. The container is not easy to implement relative to the virtual machine.Resource metrics can be collected using Heapster or Prometheus. Before the article has introduced, Prometheus Storage bottleneck and query large data volume, easy to oom these two problems. So I chose the heapster. In addition, Heapster not only internally implemented a lot of

Although some log files are usually manageable for a single application (although there are exceptions ...), it is also possible to use hundreds of or even thousands of service containers to generate logs for microservices-based applications. If you don't have a solution to collect and summarize logs, you can't basically think about getting bigger.

type encoding 1 AS path attribute is used by BGP to ensure a non-loop environment; the next hop attribute describes the next hop IP address used to go to the destination. What is the penalty? The origin attribute defines the origin of the path information. It can have one of three values: 1. IGP-the ingress is inside the starting AS and expressed as I in the BGP table; 2. EGP-routes are learned through the external gateway protocol, expressed in E in the BGP table; 3. incomplete-the route origi

XML-RPC-Remote Procedure Call (RPC), used in distributed applications to call processes on remote computers. The XML-RPC uses XML to encode information about a procedure call and sends it to the receiving computer using HTTP. Then, the returned value of the process is encoded in XML again and sent back to the caller's computer through an HTTP connection.
