Configuring a failover cluster in Windows Server 2022 is much simpler than in previous versions of Windows Server. Before a cluster can be configured, run the Validate A Configuration Wizard to verify that your hardware is configured in a fashion that is supportable. Before you can run the Validate A Configuration Wizard, however, the Failover […]
One nice new advantage of using Windows Server 2022 is the ability to set up a cluster on systems not part of the same domain. Windows Server 2022 allows you to set up a cluster without using Active Directory dependencies. You can create clusters in the following situations: Single- Domain Cluster All nodes in a […]
Taking high availability to the next level for enterprise services often means creating a cluster. Normally you have two types of clusters: failover clusters or high- performance clusters. In a failover cluster, all of the clustered application or service resources are assigned to one node or server in the cluster. If that node goes offline […]
When you choose to use live migrations, one of the settings you configure is the type of authentication you can use. Choosing the authentication type is a feature listed under the Advanced Features of live migration. You can choose two types of authentication (as shown in Figure 13.8): Kerberos or Credential Security Support Provider (CredSSP). […]
One nice feature of virtual machines is the ability to set up advanced features. In the Advanced Features section (see Figure 13.7), there are multiple settings that you can configure. MAC Addressing The first thing that you can configure in the Advanced Features section is setting a MAC address. The MAC address is a physical […]
Since we have been discussing network load balancing, I want to delve a bit deeper into Azure’s network load balancing tool called Azure Load Balancer. Azure Load Balancer has three different SKUs that you can choose from: Basic, Standard, and Gateway. Each is designed for specific scenarios and each has differences in scale, features, and […]
Upgrading an NLB cluster is a fairly straightforward process. The first thing that you have to do is stop the NLB cluster. There are two ways to do so: ■ Use the stop command to stop the cluster immediately. This also means that any current connections to the NLB cluster are killed. ■ […]
You can install NLB nodes like any other server build. You can install NLB by using either Server Manager or the Windows PowerShell commands for NLB. First make sure that all NLB servers have the most current updates, provisioned with appropriate resources (typically with multiple network interface cards for capacity and responsiveness), and monitored for […]
This section discusses onsite network load balancing (NLB). Performing NLB using Azure will be discussed later in this chapter. So, the first thing we have to discuss is why you would choose to use NLB. NLB lets you configure two or more servers as a single virtual cluster. It’s designed for high availability and scalability […]
High availability is a buzzword that many application and hardware vendors like to throw around to get you to purchase their products. Many different options are available to achieve high availability, and there also seems to be a number of definitions and variations that help vendors sell their products as high availability solutions. When it […]
