Virtualization as a game-changer in the ever-changing environment of the IT infrastructure has helped organizations to streamline their resources, minimize costs, and achieve higher scalability. Yet, in order to derive maximum benefits of virtualization, following specific virtualization best practices that are aimed to achieve maximum efficiency is required. This blog post shall address strategies that will help you on your way to an effective and scalable virtualized environment.
Understanding Virtualization
Virtualization can be defined as the virtualization of the physical hardware, servers, storage devices, or networks. Through the technology of virtualization, organizations can have numerous virtual machines (VMs) on the same physical machine thus enabling better utilization of resources and flexibility.
Why Virtualization Matters
Gartner report indicates that the market of virtualization is predicted to be $14.5 billion worldwide by year 2025. This is boosted by the rising need to have cost effective and scalable solutions in diverse industries. Virtualization is not just less expensive in terms of hardware but also easier to manage and improves disaster recovery.
Real Life Situation: One of the major financial services companies has adopted virtualization in all its IT systems and this has seen a cost of hardware cut by 40 percent and the efficiency of its operation to increase. Virtualizing their servers meant that they were able to roll out new applications quicker and to dynamically allocate resources depending on demand.
Major Virtualization Best Practices
1. Select the Best Virtualization Technology
The initial process in this process of virtualizing is the choice of the right technology. There are a number of different virtualization solutions, such as Type 1 (bare-metal) and Type 2 (hosted) hypervisors.
- Type 1 Hypervisors are directly executed on the machine and are more secure and performant. These are VMware vSphere and Microsoft Hyper-V.
- Type 2 Hypervisors are operating system based and are generally easier to configure. Examples of these include VMWare workstation and oracle virtualBox.
Professional Perspective: The Value of Making a Right Choice
It is important to note that as per the virtualization expert Dr. Emily Carter, the right choice of hypervisor is the key to performance and scalability. Type 1 hypervisors are normally more suitable in an enterprise setting because of their effectiveness and straightforward access to hardware capabilities.
2. Maximize the utilization of Resources
The possibility of dynamically allocating resources is one of the most important features of virtualization. But the wrong distribution may result in a performance bottleneck. The following are some of the measures to maximize resource allocation:
- Right-Sizing: Examine the resource need of your VMs and assign resource need. Do not provide excessively, which may result in the wastage of resources and poor performance in terms of business.
- Dynamic Resource Scheduling: Take advantage of resources such as VMware Distributed Resource Scheduler (DRS) to automatically assign resources to demand in order to make the best use of the available performance of your virtual environment.
Real-Life Application: One of our mid-sized healthcare providers has applied the right-sizing methods and used 30 percent less virtual machine resources. This change has led to a better performance as well as a huge saving in terms of cost.
3. Put in place Storage Optimization Methods
A virtualized environment is likely to have bottlenecks in storage performance. The following are the best practices that can be used to increase storage efficiency:
SSDs: SSDs have a higher data access speed than the traditional hard drives, and thus, greatly enhance the performance of VM.
Thin Provisioning: It is a method by which you can only allocate the storage capacity when there is a need and this removes wastage and enhances efficiency.
Professional Opinion: Virtualization Storage
Marc Smith, a storage consultant argues that to be successful in virtualization, it is essential to maximize storage solutions. SSDs can help significantly improve performance and also lower costs by implementing thin provisioning.
4. Do Backup and update Virtual environment regularly
It is important to ensure that your virtualization software is maintained in order to keep the software up to date to maintain performance and security. Periodic updates usually involve the addition of features, performance enhancement, and bug fixes that may be used to optimize your virtual infrastructure.
5. Adopt Intense Security Procedures
Security should be one of the priorities in a virtual environment. The following are some best practices towards improving security:
- Network Segmentation: Aim at segregating network traffic using virtual LANs (VLANs) to minimize the possibility of future transgression by hackers.
- Access Controls: Strict access controls should be enforced to prevent unauthorized persons who may access sensitive systems and data.
Real-Life Case: This was a case of a global retailer when hacked because of poor security controls in their virtual environment. Once they had effective security controls such as increased access controls and frequent security audits, they very much diminished their chances of future attacks.
6. Measure Performance on a Continuous basis
It is possible that constant monitoring of the virtual environment can detect the problems with performance in time. The major measures to be followed are:
- CPU Usage: Check the CPU usage in your VMs to observe possible performance bottlenecks.
- Memory Usage: Keep watch on memory usage so that VMs can be able to utilize the required resources to run their tasks effectively.
- Disk I/O: Evaluate disk input/output functions to make sure that storage is not a bottleneck.
- Expert Advice: The Significance of Surveillance.
According to IT consultant Dr. Lisa Thompson, to keep your virtual environment healthy, it is necessary to monitor it on a regular basis. Early identification of problems will allow you to make corrective action before it will affect the performance.
7. Disaster Recovery Planning and Backup
Any virtual environment must have a solid backup and disaster recovery plan. Periodically backup your VMs and test your recovery plan, so that you will be able to restore operations within a short period, in case it fails.
Real-Life Story: A media house had lost a good amount of data after being hit by a hardware failure. Nevertheless, due to an elaborate backup and disaster recovery plan, they could rebuild their virtual environment within hours and down time and data loss were minimized.
8. Use Automation Tools
Automation can significantly improve the efficiency of the virtual environment. Consider the use of automation tools in:
- VM Provisioning: This is used to automate the process of deploying new virtual machines so that less time is spent and fewer errors are made by human employees.
- Patch Management: Have software updates and patches and use automation to keep your virtual environment safe and up to date.
9. Capacity and Scalability Planning.
Your virtual environment has to increase as your organization expands. Assess your capacity requirements on a regular basis, and take future capacity growth into consideration so that your infrastructure can feature higher workloads.
Conclusion
Virtualization is a best practice that should be adopted by organizations that are interested in streamlining their IT infrastructure in order to generate efficiency and performance. These strategies will enable you to increase the efficiency of resources, minimize expenses, and make operations more effective.
