- - - - Horizontal Scalability means increasing the number of instances / systems for your application
        Eg : common for web applications
        
        Autoscaling
        
        Load balancer
      - Vertically scalability means increasing the size of the instance
        Eg: Application running ont2.micro , running into t2.large [common for DB, RDS ]
        From : t2.nano - 0.5G of RAM,1vCPU
        To: u-l2tbl.metal - 12.3TB of RAM . 448 vCPUs
      - High Availability : High availability means running your application / system in at least 2 data centers(AZ)
        
        Auto Scaling Group multi AZ
        
        Load Balancer multi AZ
    - - Application LoadBalancer
        
        Create EC2 instances with userdata script and same Security Group , source targetting to the loadbalancer security group
        
        then create application loadbalancer and new target group then include the ec2 instance , we can create second target group for diffrent path
        -set health check parameters and regions , review all details and create the application loadbalancer
        
        once its active then check in browser
        
        we can create new target-group and add rules to the application load-balancer
      - Network LoadBalancer
        
        Create EC2 instances with same security group and all source from anywhere as we are using TCP layer for loadbalncing the traffic
        
        Create network loadbalancer , specify the health check parameters and create Target Group, review and check for target group ip are healthy after creating loadbalancer and once loadbalancer is active check in browser
      - Classic Loadbalancer
        
        3 EC2 instances with same user data script running and Having SG and SG Group source is cls-loadbalancer-sg
        
        Create classic loadbalancer , with "cls-loadbalancer-sg"
        
        Now check in browser for loadbalncer link , requests from browser is routed between ec2-instances
      - ===============================================GateWay LoadBalancer================================================
        
        Gateway Load Balancers enable you to deploy, scale, and manage virtual appliances, such as firewalls, intrusion detection and prevention systems, and deep packet inspection systems. It combines a transparent network gateway
