Like any new technology, users are easily attracted by the benefits of virtualization. These advantages do exist and are readily available. I do business Management assistant The results of the study show that the actual measurable yield is very considerable. Almost every enterprise achieves multiple goals in such areas as resource integration, supply management, disaster recovery, security, and consistency (averaging 5 or so, individual units reaching 10, or more). More often than not, the benefits of virtualization technology are seen, and the need for Virtual system Management (Vsm:virtual system Management) is neglected. In this article I will explore the need for VSM and the reasons why enterprises should first consider VSM in their internal needs.

The importance of virtual system management (VSM)

To me, the so-called VSM is a collection of all the subject areas needed to manage the entire virtual system, not just virtual machines or hypervisor managers. VSM includes traditional systems management disciplines such as supply relationships, performance management, patch management, performance planning, Backup and recovery, configuration management, process automation, and even more, as well as new disciplines such as virtual machine management, hypervisor management, dynamic migration, and virtual mirroring management. If you deploy a virtual system without sufficient virtual machine management mechanisms, problems such as the following will occur:

The virtual machine is deployed without control; Use software certificates that are not audited by any contract; Configure the system in a publicly exposed manner (such as Web and FTP servers); The dormant virtual system mirrors do not have anti-virus and illegal patches; In such cases, security and consistency can be compromised.

The uncontrollable nature of virtual machine deployments or misuse of virtual machines increases the overhead of additional software licenses, system management personnel and it costs, virtual drivers and data storage location allocation, management tools, performance metrics, security management, and more.

Because it is possible to assign only a limited amount of hardware resources to a new virtual machine (CPU, memory, bandwidth, and so on, and even worse, configuration errors can cause a failure to connect a virtual machine to a corresponding storage device, network, server, or desktop resource, which could cause performance impact. It can also lead to problems with end-user availability and downtime.

Because the hardware server's allocation of virtual workloads is not based on actual capacity planning, but on the assumption of worst-case scenarios, it is impossible to achieve efficient integration rates. This will reduce the cost advantage of virtualization and increase unnecessary costs for hardware and software.

Because of the increased number of virtual machines that managers across the department need to manage, their productivity will be reduced. This may reduce their ability to deal with day-to-day tasks, and it will not be possible for them to add value to their strategic project work.

Use virtual system Management to improve infrastructure

Even a single virtual machine deployment that is not managed is likely to raise some real-world problems. For example, the head of an IT department I met earlier this year told me about a system administrator who occasionally deploys a new virtual machine in their production network (using a valid Dynamic Host Configuration Protocol server). He was going to deploy one of these virtual machines on the test network. As a result, call center workstations will not be networked properly, and call center operators will not be able to access their network clients ' service applications. They found the problem after the user submitted multiple problem reports. And in a number of IT departments work together to complete the troubleshooting work after the problem is resolved. One or more virtual system management control mechanisms can prevent similar occurrences, such as:

The change and Configuration management tool can automatically detect unauthorized modifications to the production network. The system will remedy the changes immediately (or not even allow modifications), remedy changes primarily by reconfiguring the virtual machine, isolating the virtual machine from the production network, or completely shutting down the virtual machine (where the system automatically sends a message to the network administrator and opens a list of issues for detection).

Automatic provisioning ensures that the correct network configuration is applied to new virtual machines even before the virtual machine is deployed. Using an integrated tool for supply problems may require a specific template or process that requires a check box for testing or production to be used on a template or process, which is less likely to be overlooked.

Process automation tools Ensure that only one pre-approved set of virtual units is deployed--checked against a standard configuration template and authorization change list, and any surprises can result in a request to oppose the change or an artificial license Any one of these solutions can eliminate the human error The latter closes a problematic virtual machine deployment.

Value discovery and innovation management can easily detect the addition of a new server in a production network, and can even describe the characteristics of this server as a secondary Windows DHCP server, shortening the time to discover problems and resolve problems. This is not necessary to prevent the problem from occurring, but it can shorten the cycle of problem resolution and reduce the impact on the system.

Performance and application management tools can detect IP address conflicts, disconnect between clients and servers. Through the monitoring of virtual and real-world transactions, problems can start red alerts to help the front desk and even shorten the time to resolve the problem before the call center operator discovers the problem.

Summary

This is just a poor management issue in real-world examples, as well as a few columns of sufficient virtual system management how to block these problems. In fact, the number of problems caused by poor VSM and the number of good VSM can be solved far more than I can enumerate in this essay. While nothing is wrong, if you do not use a virtual System Management protocol in a virtualized configuration, it can result in high user configuration overhead, inefficiency, poor performance, long downtime, high risk, and many other major problems.
