A distributed deployment method and system with lossless transactions

Abstract

The present invention relates to a distributed deployment method and system with lossless transactions. The method includes: step 1: establishing a connection between a front-end processor and multiple web application ends; step 2: copying the configuration of the web application end in the front-end processor application, and Load the copied configuration into the memory and process it; Step 3: Set global variables, read the processed configuration in a loop, so that the front-end processor can allocate resources equally to each web application; Step 4: The front-end processor receives customers According to the request sent by the terminal, extract the url of each wed application in turn; step 5: detect the wed application to determine whether the obtained url is available, if yes, perform step 6; otherwise, perform step 7; step 6: the client passes The front-end processor accesses the wed application end, end; step 7: the client accesses the standby url in the front-end processor, end. By increasing the front layer, system stability and user perception are improved.

Description

technical field [0001] The invention relates to a distributed deployment method and system for lossless transactions. Background technique [0002] With the development of the Internet era and the increase of network users, users have higher and higher requirements for the systems they use. No matter how high the performance of a single host or application is, it can no longer meet the requirements. Alibaba proposed the concept of de-IOE and realized de-IOE To reduce maintenance costs and achieve cost reduction, more and more service providers are adopting distributed cloud deployment, load balancing, multi-machine hot backup and other deployment solutions to avoid single point of failure and performance pressure. [0003] At present, most of the distributed deployments of large-scale systems are applications that are evenly distributed to multiple devices through load balancer configuration transactions. If the application is abnormal, the request will no longer be distrib...

Problems solved by technology

[0003] At present, most of the distributed deployments of large-scale systems are applications that are evenly distributed to multiple devices through load balancer configuration transactions. If the application is abnormal, the request will no longer be distributed to the application. However, when the transaction volume is very large, such as dozens to hundreds of transactions per second, the period from the load balance judgment abnormality to the distribution block has already caused a large number of transaction failures , cannot be accepted normally
