Case: Use redis for publishing and subscriptionRedis publish and subscribe
Redis pub/sub is a message communication mode: the sender (pub) sends messages, and the subscriber (sub) receives messages.

JMS is a Java Message Service. JMS clients can transmit messages asynchronously through the JMS service. JMS supports two message models: point-to-point (P2P) and publish/subscribe (pub/Sub), that is, point-to-point and publish subscription models.P2P
The P2P model has the following concepts: queue, sender, and receiver ). Each message is sent to a specific queue, and the receiver obtains the message from the queue. The queue retains messages until
of the account.

my idea is to get a unique identifier for the current subscription number when the user orders in one of the subscription numbers. When the order is generated, an identity is inserted into the database.
Now there is a requirement, that is, multiple subscription numbers are common to one site, but make a difference when you order.So, I hope you pass by friends t

We know that when you create a new subscription, you must use the actual server's real name, IP address, alias can not, in the same LAN is no problem. But two servers are not in the same LAN.The simplest way to implement a subscription and release is to:One: View the name of the actual server:Two: Add the IP address and name of the subscriber to be pushed in the hosts file of the published server, remember
There are customers who want to get all the load balancers in an Azure subscription with a single command.There is no such command in PowerShell for Azure at this time.

A publish Subscription (PUB/SUB) is a message communication pattern that is primarily designed to decouple the coupling between a message publisher and a message subscriber, which is similar to the observer pattern in design patterns. Pub/sub not only solves the direct code level coupling between publishers and subscribers, but also solves the coupling between the two on the physical deployment. As a pub/sub server, Redis serves as a message routing f
