Working-up with Application Load Balancer

So, now our scenario is distributing traffic based on our URL path, currently we 2 instance which one has homepage of our website and 3 instance which only has products page of the website

We want is whenever traffic comes for products page it should be served through 3 products instance

• For doing this we will use ALB, but first we need to create Target groups for ALB
  Go to EC2 Dashbroad and scroll to Target Groups > Create target group
  
• Input the Target group name and path
  
  
• Scroll down and select Advanced health check settings as shown below
  
• Once target group created select it > Actions > Register and deregister targets
  
• Select Home-EC2 > Add to registered > Save
  
• Similarly created target group and register Products-EC2 to it
  

• Once Home and Product target group is created, create ALB
  

• Input the Name
  
• Scroll down and select all Availability Zones, this basically allows ALB to server traffic to instance in any 6 AZs
  
• Select default security group
  
• Select Existing target group and select Home target group previously created
  

• Now select your ALB and go to Listeners tab then click on View/edit rules
  
• Click + button > Insert Rule
  
• Select Path is… > give path as */products/* then Forward to… to Products target group > Save
  
• Now try to open ALB DNS in browser it should open This is our Homepage page
  

• Now if you open <LB-DNS>/products/products.html it will open This is our products page page
  This is getting served through our 3 products instances
