What is Windows Network Load Balancing?

Windows Network Load Balancing (NLB) is an optional component of Windows Server. It load balances network traffic, sent to a cluster virtual IP address, among multiple servers in a cluster. It requires Microsoft Clustering to be used.

When should you use a network load balancer?

Using a Network Load Balancer instead of a Classic Load Balancer has the following benefits: Ability to handle volatile workloads and scale to millions of requests per second. Support for static IP addresses for the load balancer. You can also assign one Elastic IP address per subnet enabled for the load balancer.

How do I monitor my Network Load Balancer?

You can use Amazon CloudWatch to retrieve statistics about data points for your load balancers and targets as an ordered set of time-series data, known as metrics. You can use these metrics to verify that your system is performing as expected. For more information, see CloudWatch metrics for your Network Load Balancer.

Does a load balancer have an IP address?

A public load balancer has a public IP address that is accessible from the internet. A private load balancer has an IP address from the hosting subnet, which is visible only within your VCN. You can configure multiple listeners for an IP address to load balance transport Layer 4 and Layer 7 (TCP and HTTP) traffic.

Does AWS ELB have an IP address?

For more information, see Routing traffic to an ELB load balancer in the Amazon Route 53 Developer Guide. The load balancer has one IP address per enabled Availability Zone. These are the addresses of the load balancer nodes. The DNS name of the load balancer resolves to these addresses.

What is network load balancing in Windows Server 2008?

This chapter of Windows Server 2008 R2 Essentials covers a concept referred to as Network Load Balancing (NLB) clustering using Windows Server 2008 R2, a key tool for creating scalable and fault tolerant network server environments. In previous versions of Windows Server, cluster configuration was seen by many as something of a ‘black art’.

Where can I find network load balancing manager?

To open Network Load Balancing Manager in Server Manager, click Tools, and then click Network Load Balancing Manager. The following table provides links to additional information about the NLB feature that is available on the web.

How many nodes are needed for network load balancing?

Each server in a cluster is referred to as a node. Network Load Balance Clustering support varies between the different editions of Windows Server 2008 R2 with support for clusters containing 2 up to a maximum of 32 nodes. Network Load Balancing assigns a virtual IP address to the cluster.

Is there a load balancer for Windows Server 2016?

Windows Server 2016 includes a new Azure-inspired Software Load Balancer (SLB) as a component of the Software Defined Networking (SDN) infrastructure. Use SLB instead of NLB if you are using SDN, are using non-Windows workloads, need outbound network address translation (NAT), or need Layer 3 (L3) or non-TCP based load balancing.
