Windows Azure Platform Family of articles CatalogThis article is a supplement to the author's previous article on how to handle the ASP. NET session under the instance scenario for multiple VMs in Windows Azure Cloud Service (13).Here I will introduce both IaaS and PAAs platforms.　　We know that in the Windows Azure platform, the session needs to be handled with care. For the IaaS platform and PAAs platform,

manage Docker daemon on these virtual machines, only one Docker node registration is successful and the other Docker node registration fails with the error message: Docker daemon ID is already occupied. Cause Analysis: If the Docker Daemon ID on more than one Docker host is the same, the Docker node registration failure occurs swarm. The principle is as follows: (1). Docker daemon at startup, it assigns an ID value to itself, which is created by Trustkey and Trustkey stored in ~/.docker/key.jso

OpenStack Introduction OpenStack is an open source IaaS implementation that consists of a number of interrelated subprojects, including computing, storage, and networking. With the launch of the Apache protocol, more than 200 companies have joined the OpenStack project since its inception in 2010, including Att, AMD, Cisco, Dell, IBM, Intel, Red Hat and so on. The number of developers currently involved in the OpenStack project is 17,000 +, from 139

first, the basic knowledge of OpenStackOpenStack is a free software and open source project that was developed and initiated by NASA and Rackspace to Apache2.0 licenses (compatible with GPLv3 and DFSG).OpenStack is an open source cloud computing management Platform project, composed of several major components to accomplish specific tasks. OpenStack supports almost all types of cloud environments, and the project aims to provide a simple, scalable, rich, standard, unified cloud management platfo
