Cloud computing challenges to server O & M

After the introduction of cloud computing, O & M focuses not only on the normal operation of the previously managed devices, but on the smooth network, we will also focus on active resource supply, automatic configuration, sustainability, and traceable real-time configuration management.

In traditional O & M management, in order to ensure reliability and scalability, you must not only support the deployment phase, but also monitor the running status of the application at any time, determine whether a node is invalid or the load is too high. In the event of an exception, the Administrator starts the backup server based on the preset workflow, run the corresponding management script to configure and initialize the new server. In the cloud computing environment, some O & M personnel are responsible for the operation of physical devices and some are responsible for application-related monitoring and management. O & M personnel no longer rely on traditional network management methods to locate system faults. They need to analyze the system operation efficiency and fault causes more deeply through the cloud computing management platform and virtual device management platform.

In a cloud computing environment, virtual machine virtual image Disk Files package basic operating systems, applications required by customers, and middleware required for running applications, it eliminates the need to perform complex installation and configuration for users in the traditional environment and is ready to use out of the box. In fact, it has become a virtual asset for enterprises. This is different from the traditional environment in which the host running environment needs to be retained and installed software is saved. Loading virtual machine image files at any time means that new virtual devices can quickly enter the production status as needed, in particular, the preparation of some testing and development environments can be quickly restored to the desired state through the original virtual image.

Before cloud computing practices, the vast majority of application services in the data center were deployed on physical machines. As physical devices gradually become older, their performance gradually declined, the stability and reliability of the running application software are greatly affected. Migrating services to a new system is at great risk: on the one hand, developers are at high mobility and it is difficult to find the relevant personnel of the original development team when migrating services; on the other hand, software compatibility issues with the new running environment. The specific interfaces or function libraries that the software depends on are not necessarily compatible in the new system. After the introduction of cloud computing technology, people can use the new virtualization auxiliary technology (P2V) to migrate application services and operating systems from physical servers to virtual environments, the Administrator no longer needs to touch the code of applications closely integrated with the system, which greatly improves the feasibility and success rate of system migration. The migrated servers can be managed on a unified interface, and when these servers are shut down due to faults, you can automatically switch to other alternative virtual servers on the network to avoid service interruption.
