Setting up a load balancer on AWS
This section covers main steps of setting up a classic load balancer on
AWS.
This load balancer will redirect client requests traffic to different
Talend Runtime
instances managed by Auto Scaling group.
Procedure
-
In Step 1, Define Load Balancer section, fill settings as shown below:
Information noteNote: In this demo, you will redirect the traffic on Load Balancer URL (on http port 80) to Talend Runtime Instances URL (on http port 8040 - as default Talend Runtime services listening port). -
In Step 2 and 3 (Assign Security Groups and Configure Security Settings),
choose default Security Groups and default Security Settings (make sure you have
inbound port 80 opened).
-
In Step 4, Configure the Health Check and configure the Advanced
Details sections:
- Set up the ping protocol, port number as shown below.
- Make sure the ping path points to Talend Runtime default services page on /services.
- Leave Advanced Details by default (change per your need if required).
Information noteNote: In this setting, the load balancer will request /services web page on each Talend Runtime EC2 instance every 30 seconds to check if the Runtime host is in good health, if not getting health Response (http return code: 200) in 5 seconds with threshold of 2 retries, Load Balancer will deregister unhealthy instance so making sure all traffic can be directed to healthy Talend Runtime host. -
In Step 5, leave AZ distribution and you will not need to add EC2 instance in
this step (as this Load Balancer will serve Auto Scaling Group in a dynamic
way).
-
In Step 6, add tags as Name –
TalendRuntimeAutoScalingLB/
-
Once created, the new Load Balancer is available to be used.
