Management Considerations for Virtual Server Environments

Management in a virtualized server environment is sometimes more complicated than managing a physical-physical server because in a virtualized environment, the complexity of deploying the server is much more complex than in the physical environment. So enterprises in the management of virtual server environment need to pay attention to what issues?

Configuration management planning

Whether it's public or private, you have to plan the server configuration for the virtual environment and take control of the changes. Instead of lengthy and complicated scripts and lengthy platform testing, you need to be able to deploy servers quickly and easily with the right configuration. You also need to control the server changes over time. Has the administrator made any adjustments and caused the server to get out of optimal configuration?

The first question you should ask when a virtual environment has a problem is whether or not the configuration is considered a change because most of the problems with the virtual server environment are due to some intentional or unintended adjustments to the configuration. Avoid these disruptions and provide better control of the environment with a reasonable configuration. You can choose the appropriate tool such as http://www.aliyun.com/zixun/aggregation/13494.html">Puppet.

Be careful about the problem trap

In today's virtual environments, virtualization is being phased in using configuration wizards and preconfigured devices, and anyone outside of the experts can create and maintain virtual environments. This is precisely the problem. Although the virtual environment looks simple, installation, configuration, and management are complicated. Technology is not a problem, the problem is the compliance. The simple appearance may mean that the underlying is complex and the problem is just like the tip of an iceberg. At this time, the more knowledge about the underlying knowledge, the better. Being able to locate the problem correctly is a key step in restoring the system.

By virtualizing or migrating core production applications to cloud services, organizations can avoid most of the headaches. This eliminates the potential for mistakes and maintenance, and the large number of available cloud services provides organizations with a modern data center that meets their needs. Organizations are beginning to take virtualization routes, be it private or public, make sure employees are well trained. Virtualization can give organizations amazing benefits, but they need to be well-controlled.

Ignore the virtual infrastructure

In a physical server environment, server usage increases and you may continue to use the old firmware with few patching, since a single server runs only one application. But with server virtualization, performance can be compromised if you fail to pay attention to the maintenance of your virtual infrastructure and, worse yet, can result in hundreds of server downtime. Because all of your virtual servers are running on the hypervisor, if you neglect maintenance, virtualization servers running on the hypervisor experience performance or availability issues.

At this point you need to have a complete understanding of the infrastructure and pay attention to the performance threshold. If the environment does not change, but you suddenly find that the operation is not stable, then to understand what may be a resource layer overload led to performance problems. To do this, you need to choose a monitoring tool with diagnostic capabilities and trend analysis.

Virtualization Environment Configuration Checklist

Managing Your Virtual Environment The primary issue is managing and maintaining a list of virtualized infrastructure and related information such as virtualized system configuration information, usage, or physical location of the host. In the event of a disaster, this information is crucial to a quick recovery, and unfortunately this work is often overlooked.
