Single instance means there is only 1 instance that will bear all the traffic load whereas Load balanced server means that there will be a cluster of servers that will host the application and load will be balanced distributed among them. Auto Scaling means that the number of instances will be expanded / shrunken based on the rule. Rule could be the traffic count , response time etc. | ||||

| Ans. Load Balancing is a provision to improve performance by reducing load on a single machine / server. Traffic or load is distributed among different machines and hence resulting in better performance / response time by leveraging more resources. Failover is a provision to achieve better availability by switching to a backup server in case of failure. Load Balancing aims as improving performance whereas failover aims at improving availability. We can achieve both together by using a Load Balancing system which will isolate an instance in case of it's failure. | ||||
