Monitor virtual work environment is necessary to maintain system uptime. This article describes how to protect the security of virtual environments, deploy, and monitor virtual work environment.
Working environment to protect the security of virtualization
At present there is a need to face the question: a lot of virtual working environment, lack of system security manager, resource requirements and virtual machine monitoring and other work of sufficient importance, these are the virtual work environment need to be considered. But ignore all of these issues will lead to security breaches, and virtual machine performance problems and system downtime consequences. Monitor virtual work environment is necessary to maintain system uptime. This article describes how to protect the security of virtual environments, deploy, and monitor virtual work environment.
Working environment to protect the security of virtualization
Deployment of virtual working environment, administrators often forget to spend time to reasonably protect the safety of the working environment, this is a very important issue. In fact, in terms of the Hypervisor that many still relatively safe, but there is room for improvement can continue. In addition, the result Hypervisor very easy to become unsafe, such as modifying the default settings or configuration error. Because the virtual work environment, a physical server to run many virtual servers, physical servers can directly affect the safety of running on the host all the virtual server's security, so security issues can easily be enlarged.
Traditional security solutions to problems can not be fully applicable to the virtual work environment, there are still some specific issues to consider. Therefore it is necessary to take some time to figure out the virtual work environment safety, the virtual work environment on the composition of all components (including the host, virtual machine, network and management server) configuration recommended security settings.
Protection of the host server is indeed not be overstated in any case. Imagine the host server is like a castle to protect the things inside the castle - the virtual machine. If an attacker break the castle's protective measures, you can freely access to anything inside. It is necessary to the extent possible, adequate protective measures to ensure safety of the castle, of course, do not forget to put enough water inside the moat, to improve protective measures. For this reason, many third-party security products to provide businesses, especially in monitoring and protection of virtual machines, hosts and virtual network security products.
As the growing security risks and some lead to misunderstanding of the virtual machine insecure existence, many security administrators to manage virtual hosts very carefully. Take the time to explain to the company's security department in a virtual work environment the role played by security. Also listed in the further protection of the host and virtual machine measures taken additional steps. In the virtual environment, they know the importance of security, the will be very happy to cooperate with the work.
Deployment of virtual work environment
In fact the creation of the virtual machine is very easy, but once the virtual machine expansion will bring up a lot of problems. Virtual environment in which the biggest problem is the spread of virtual machines or virtual environment, virtual machine does not control growth. Here, StarTrek followers should be able to recall them in the popular "TheTroublewithTribbles" in the lovely alien to speed quickly copied, so that over the spacecraft's food supply. Very similar to the spread of virtual machines, virtual machine, without seriously considering the consumption of host resources, the freely create a virtual machine. Therefore, the host server is difficult to load quickly these virtual machines.
In response to the spread of this virtual machine, you can use to deploy some specific products that can support the charge, the virtual environment can also create a report the use of resources. In addition, the limit authorized users to create virtual machines to build a new virtual machine requesting confirmation process can prevent the spread of virtual machines and can not control. Need to consider any request to create a virtual machine the legitimacy of the establishment of a licensing process to force the user need to create a virtual machine once again to consider whether there is a genuine need. Finally, create a resource pool to assist the new restrictions on the virtual machine host server for the amount of resources used.
Control the spread of virtual machines as early as possible is very important, as far as possible before the problem. Otherwise it may run out of all the host resources and virtual machines will have lower performance bottlenecks. IT supporters need to realize the virtual machine is not free, no matter how its configuration, may bring associated costs. Strictly control the virtual work environment is to limit unnecessary virtual machine host server key to growth.
Monitor virtual work environment
Monitoring the virtual work environment for normal operation and commitment to maintain its function is very important. Typically, the problem may not be obvious, a good monitoring system can send alarms need to be resolved. In the virtual work environment, because a considerable number of virtual machines running on a host, and all compete to use the virtual machine host resources, so there may be a small problem a great deal of influence. Attach importance to monitoring the issue very important, if not control, the virtual work environment can not notice the problem by trying to warn because simply no attention.
There are several elements which need monitoring, such as performance, server hardware and virtualization software-specific alerts and events. Host hardware failure can interrupt the virtual work environment, despite the current many related technologies (such as high reliability and fault tolerance) is to minimize system failure downtime. Read fan, drive and memory module when the problem can take immediate measures to minimize the interruption of the work environment.
In the virtual work environment, because there are many virtual machine host resources and the phenomenon of competition, and a bottleneck problem can largely affect the performance of virtual machines, so monitoring the performance of the host and virtual machine is necessary. Resource bottleneck usually is not obvious, monitoring host performance can assist identification of potential bottlenecks need to rectify. Monitor virtual machine performance when the need to rely on a number of tools. These tools are designed for use in the virtual work environment, because many of the operating system tools such as Windows performance monitoring does not apply to the virtual layer, and the measure for a particular counter and may produce incorrect results.
Root cause of performance problems are often not obvious, but the virtual machine and host server will generate a series of effects. Should therefore be configured in a virtual work environment monitoring system, in-depth understanding of the report to take the initiative to remove bottlenecks and problems of specifications and data. Alternatively, you can consider a lot of third-party merchants provide monitoring and reporting tools. These tools and built-in virtualization products is very strong compared to the tools, and to a large extent can enhance monitoring capabilities.
