# Deka GLB

**Deka GLB (Global Load Balancer)** is a feature in the Cloudeka portal service that is used to improve end user performance by directing users to the nearest data center using geolocation. The primary goal of using Deka GLB is to increase the availability, performance, and reliability of a web application or service by evenly distributing the workload among servers located in various data centers or physical locations around the world. Cloudeka load balancer provides several features:

* Multiple protocols, load balancer supports multiple protocols to meet your needs. Currently several protocols are available:

       **a. TCP**

        **b. HTTP**

        **c. HTTPS**

* Health Check, to determine the condition of the backend instance periodically. This will automatically stop sending traffic to unresponsive instances.

On load balancing, there are 3 algorithm methods used, including the following:

<table><thead><tr><th width="226"></th><th>Description</th></tr></thead><tbody><tr><td>Roundrobin</td><td>This is a load method that is given sequentially from one server to another so that it forms a loop.</td></tr><tr><td>Least Connection</td><td>This is a load method that is assigned based on the server that has the fewest connections in the list of available servers.</td></tr><tr><td>Source</td><td>The method selects the server to use based on the hash of the source IP address from which the user made the request so that in this method ensures that the same user will connect to the same server</td></tr></tbody></table>

Before creating a Load Balancer, you must first have an Instance. If you don't have an Instance yet, you can create an Instance first. For an explanation about creating a create VM instance you can read at [Create VM Instance](/deka_flexi/deka_flexi_compute/create-a-vm-instance.md#create-instance-from-public-image).
