# Create Network Load Balancer (NLB)

{% hint style="info" %}
Creating a Target Group is a prerequisite for creating a Load Balancer. [Learn how to create a target group](/basics/core-infrastructure/networking/load-balancers/create-target-group.md)
{% endhint %}

* Go to the "Networking > Load Balancers" tab.
* Click on "Create Load Balancer > Network Load Balancer".
* Fill in the following fields:
  * Load Balancer Name - a display name for your LB
  * Description
  * Region - select the region where you want to deploy your LB
  * VPC, Subnet - select the VPC and Subnet within which you want to place your LB
  * Security Group - Choose a security group for your LB. You can create a new security group with custom inbound/outbound rules for your LB, from the "Networking > Security Groups" tab. [Learn how to create a security group.](/basics/core-infrastructure/networking/security-groups.md)
* Select a performance tier. We provide the following performance tiers:
  * **Standard** - 4 vCPUs, 8 GB RAM
  * **Pro (coming soon)** - 8 vCPUs, 16 GB RAM 

{% hint style="success" %}
A **Standard** NLB can support upto 90,000 simultaneous connections and 350,000 requests per second (RPS).
{% endhint %}

* **High Availability** - Each load balancer is provisioned with High Availability (HA) by default. The load balancer is provisioned with 2 nodes (1 primary, 1 backup) for enhanced reliability and fault tolerance.
* **Add Listeners** - You can add multiple listeners, each of which maps to 1 target group.
  * Fill in a display name, the protocol, and port number on which it listens for traffic.
* **Pool Configuration** - 
  * Add a display name and protocol for your pool.
  * Select a load balancer algorithm appropriate for your needs.
  * Select a target group containing at least 1 active VM, for your pool.

| Algorithm             | Description                                                                                                                                 |
| --------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- |
| **Round Robin**       | Distributes requests evenly across all healthy targets — simple and effective for most workloads.                                           |
| **Least Connections** | Sends new requests to the target with the fewest active connections — best for apps where requests vary in duration.                        |
| **Source IP**         | Routes traffic based on the client’s IP address — ensures requests from the same client always go to the same target (session consistency). |
