Managing VMware Virtualization Infrastructure: Best Practices

For Wintel virtualization, VMware has clearly become a standard solution, with the most significant reduction in cost and complexity. While theoretically eliminating as many Windows-based servers as possible, it maximizes efficiency and determines which virtualization is not always easy. You need to consider the performance, nature, cost, and business requirements associated with your application. In addition, while many of the best practices in managing data centers can be moved from the physical world to the virtualized world, virtualization introduces new challenges related to culture, resource requirements, and processes. All of these factors need to be carefully considered within the context of an IT resource optimization strategy.

This article highlights some of the more important best practices that are sure to be used when it comes to virtualization infrastructure.

Taking full advantage of the rules of portfolio management to determine what should be merged or virtualized, and how portfolio management enables it and business to make informed decisions, this decision takes into account the needs of the business and the importance or value of the application. In the context of virtualization, the key to portfolio management is to help arrange which applications can and should be virtualized. Regulatory issues, application-critical tasks, business requirements, and cost structures all have a significant impact on virtualization decisions and are highlighted through portfolio management processes. By taking a multi-perspective approach to applications and systems, you can also avoid falling into a virtualization-only integration strategy and explore other approaches that might provide new and greater savings or efficiencies while minimizing risk. The portfolio also provides the basis for establishing a business case integration and virtualization through accurate tracking and allocation of costs and potential savings.

Performing or re-designing the debit mode

Deductions – A controversial issue for many organizations, can be a friend rather than an enemy in a virtual environment. Politics is a real danger to the virtualization initiative. The business unit can take charge of their significant impact and quickly propose an initiative that is considered to put their application at any risk. Accurate, transparent and fair deductions clearly illustrate the virtualization of business cases. A simple allocation pattern based on a predetermined percentage of cost sharing, or a non-differentiated logical server and physical server, will not drive business units to support virtualization. The use of monitoring tools and the facilitation of accurate cost allocation to help business users save costs has contributed to the proliferation of political debates. These can support a deduction system that provides a significant improvement to the business unit, with minimal cost savings for virtualization implementations.

Develop capacity planning functions

Previously, capacity planning was primarily a matter of concern for hosts, and multiple users and applications shared resources here. Virtualization introduces a kind of cultural change, middle-level system Manager, has always been a simple purchase of a new pool of resources to solve a series of problems related to workload conflict. Capacity planning in a virtual data center is the art of balancing risk and maximizing resource utilization. New tools to help plan and monitor the virtual environment, as well as the ability of the team to use these tools to effectively complete the work process. During the planning phase, organizations should look for tools to accurately model the workload to the most appropriate location, including indirect consumption by VMware virtual machines. Once in production, VMware's key features, such as vmotion and distributed resource Scheduling (DRS), can be balanced to work without disruption by migrating virtual machines to new targets. Although relatively new vmotion features are rapidly becoming popular, it is like a cheap and comparable option to manage traditional clusters. The Virtualization solution applies your environment through the Cirba Diagram vmotion feature and provides VMware's DRS integration, AutoFill rules where servers can be moved to avoid potential conflicts and mitigate risks.

Prepare to invest in training

The configuration and staffing processes need to adapt to new technologies. Significant changes follow the new server configuration. Of course, organizations will no longer need administrators with rich hands-on experience in some areas, and require a more comprehensive administrator role. A skill shortage and vmware-based virtualization technologies are emerging topics. Popular tools Create a high level of experience resource requirements. And because technology is emerging, "experience" is hard to come by. This not only promotes the rise in labour costs, but also means that organizations tend to neglect to train their own staff and to dabble in this new field without any favourable experience. In addition, training is imminent, so that managers and technicians can keep abreast of this rapidly evolving product suite and new complementary solutions.

Implementation of new processes to prevent virtual sprawl

In the physical server world, the Purchasing department acts as a gatekeeper to help prevent server sprawl. While the proliferation of Wintel servers may indicate that they are ineffective, today's virtual data centers can be largely free from any oversight. In a production environment, virtual machines that are created by individuals are often also managed. This direct relationship means that the group is unlikely to be free to create new VMS and add complexity. On the other hand, the application development (AD) team may not have such a motive. The ad team may find it useful to create new servers for testing and short-term, but precisely because their physics is underutilized and abandoned, so will virtual servers. If this becomes a norm, it teams will face cost-testing due to increased complexity and management time for the infrastructure. The best practice is to define the new policy, including the rules, parameters, and files used to create each virtual machine. Executing tools, tracking systems, and virtual machines through audits can help keep the VM's proliferation under control.

Increasing the virtualized infrastructure in the data center can have a profound impact on staffing requirements, management procedures and policies. Organizations that can make plans before they change and develop new best practices are successful, and they can ensure that cost reduction goals, responsiveness and better reliability can be achieved.
