IP ServerOne now offers cloud-based Load Balancer as a Service (LBaaS) in Malaysia, Singapore, and Hong Kong.

You can use LBaaS to improve your app’s performance and availability. Choose between Layer 4 (TCP) or Layer 7 (HTTP/HTTPS) load balancers that match your app’s needs. For guidance on choosing the right load balancer, visit our website here.

Overview

This tutorial will guide through launching your HTTP/HTTPS Load Balancer via the Customer Portal.

Prerequisite

• Register and log in to your Customer Portal account here.
• Guide to top-up cloud credit for load balancer deployment.

Instructions

Step 1: Once logged in, click on NovaCloud and dropdown to Load Balancers.

Step 2: Choose your desired deployment region (Malaysia, Singapore, or Hong Kong), and then click the Create Load Balancer button.

Step 3: Choose to deploy your load balancer from either Basic Creation or Advanced Creation.

The key difference is: 

• Basic Creation makes deploying a TCP load balancer easy. Just specify the traffic type and add target servers with their IP addresses and ports.
• Advanced Creation offers more detailed configurations, including ports and backends, from the start.

No need to worry, though. With Basic Creation, you can still make detailed changes after the load balancer is deployed.

Step 4: Select your load balancer plan.

Step 5: Provide a name for your load balancer, select the load balancer type (Network or Application layer for TCP or HTTP/S). By default, ports 80 and 443 will be activated.

Step 6: Pick the SSL certificate you want for encrypting traffic on port 443. You can choose a self-signed certificate or use your own.

Insert the SSL Certificate and Private Key should you select “Use own certificate” to proceed.

Step 7: Configuring the HTTP/HTTPS Load Balancer

• Provide a name for your server.
• Enter the server’s IP address and port number.
• Select HTTP/S Check to enable both active and passive health checking for your server, ensuring that traffic is directed to servers that are healthy and responsive.

**An HTTP/HTTPS health check is a way to regularly check if web servers are working correctly by sending a simple request to a server and expecting a response, including the HTTP status code and the content of the response body. If the server responds as expected, it’s considered healthy. If not, it’s marked as unhealthy, and client requests are directed to healthier servers. This helps keep web services reliable and responsive.

• Optionally, you can add multiple backend servers by clicking the Add Server button.

Step 8: Clicking on the Create Load Balancer button triggers the system to start provisioning the load balancer server, indicated by the Creating status.

Step 9: After the load balancer has been provisioned, its status will change to Active.

– Step End

Note: To monitor data transfer or make configuration adjustments, or adding backend servers, simply click on your load balancer’s name.

To modify your HTTP/HTTPS load balancer’s settings

You can make modifications to the following:

• Port Configuration
• Health Checks
• Backends

Step 1: Navigate to the CONFIGURATIONS tab and select the configuration you wish to modify by clicking its name.

Step 2: Port Configuration

For HTTP/HTTPS load balancers, you can make changes to the Port to Listen, Port Protocol, Session Stickiness, Algorithm, and Certificate Type you prefer.

Step 3: Health Checks

You can adjust the health check setting by selecting either HTTP Status or HTTP Body.

Step 4: Backends

You can adjust or add new backend servers to your existing load balancers.

• Current Backends: You can modify the Name, IP Address, Port, and Weight settings within your HTTP/HTTPS load balancer configurations.

• New Backends: You can add new backend servers by entering the Name, IP Address, Port, and Weight within your HTTP/HTTPS load balancer configurations.

– Step End

Tips

Understanding Port to Listen:

In simple terms, “port to listen” refers to a specific entry point on a computer or server where it waits for incoming data or requests from other devices on a network. It’s like a mailbox or a designated spot where messages or data arrive, and the computer is ready to process them. Each type of service or application often uses a specific port to make sure the right data goes to the right place on the computer. 

Here are some commonly used ports for your reference:
