Network Load Balancer

Initiate Load Balancer Creation

• Log in to the MyAccount portal using your credentials.

• On the MyAccount dashboard, click on Load Balancers.

Select your Load Balancer Plan

• Load balancer plans are listed by memory, vCPU, storage, and price. Choose a plan to create your load balancer.

• After selecting a plan, choose the load balancer type:
  1. Application Load Balancer (ALB):
     Works at Layer 7, making decisions based on content and application logic.
  2. Network Load Balancer (NLB):
     Works at Layer 4, routing TCP traffic based on IP and port.

• To create a Network Load Balancer (NLB), click on the Network Load Balancer (NLB) option.

• Enter configuration details (name, mode, port, SSL certificates, etc.) for front-end and back-end connections. ALB Deployment Help

Details

• Name: A default name is provided based on the selected plan, but you can modify it.

• Type: Choose between Internal or External load balancer.

Target Mapping

Backend Name

Routing Policy

• Choose a Balancing Policy:
  • Round Robin: Distributes requests evenly among backend servers.
  • Source IP Hash: Routes based on the user’s IP address to ensure consistency.
  • Least Connection: Routes traffic to the server with the fewest active connections.

How Least Connection Works:

1. The load balancer tracks active connections for each server.
2. Incoming requests are routed to the server with the least active connections.

Port

• For NLB, use a port between 1024-65535, except 8080, 10050, and 9101.
• ALB does not require a target port.

Backends

• Adding a backend is mandatory. Click Add Backend to add a backend.

• View the backend list via the dropdown.

Peak Performance Features

Create New VPC

• Enable this option to use a VPC IP as the default VPC IP for your load balancer to connect internally.

• After creating a VPC, you can see it in the dropdown list.

• There are two types of VPCs available:

Default VPC: Provided by E2E with a pre-defined CIDR.

Custom VPC: User-created, where you can also optionally select an associated subnet.

Add New Reserve IP
Enable this option to use a reserved IP as the default Public IP for your load balancer. You can dynamically update the backend resources of your applications and websites by re-assigning the reserved IP address without downtime.

After creating an IP, you can see it in the dropdown list.

Enable BitNinja
Enable this option to use the BitNinja security tool for your load balancer. BitNinja has modules for different types of cyberattacks. It’s easy to install, requires minimal maintenance, and provides immediate protection against a wide range of cyberattacks.

Timeouts
You can set different timeout values, such as connection timeout, client timeout, server timeout, and HTTP keep-alive timeout, according to your requirements.

Encryption

Encryption in Load Balancer ensures that all incoming and outgoing traffic between clients and backend nodes is securely transmitted over encrypted channels. When HTTPS/SSL is enabled, the Load Balancer terminates SSL at its endpoint, decrypts the incoming request, and forwards the traffic to the backend servers. This prevents data interception, protects sensitive information, and guarantees secure communication over the public network.

Security Group

A Security Group attached to a Load Balancer acts as a virtual firewall that manages both inbound and outbound traffic. It ensures that only permitted IP ranges, networks, and protocols are allowed to communicate with the Load Balancer and its backend nodes. When a Load Balancer is created, a default Security Group is automatically selected and applied. Users also have the flexibility to create a new Security Group or can select from the previously created security group, during the Load Balancer creation process and assign it immediately. Additionally, the newly created Security Group can be set as the default for future Load Balancers. This allows users to enforce custom access rules, improve security, and maintain tighter control over network communication.

• Inbound rules determine what type of traffic is allowed to reach the Load Balancer (e.g., HTTP/HTTPS from specific networks or public access).
• Outbound rules control what traffic the Load Balancer can send out, including allowed IP ranges, ports, and network destinations.

Configure a Security Group for Load Balancer

1. Click the “+” icon to create a new Security Group.
   

2. Enter a name for the Security Group. Adding a description is optional.You may also choose to set this Security Group as the default.
   

3. Define the required Inbound and Outbound rules based on your access needs.Click Create to finish.
   

After the Security Group is created, it will appear in the list of available groups. You can then select it from the Security Group dropdown menu while creating or updating your Load Balancer.
