    Answer :

    Xen

  2. Question 44. What Are Spot Instances In Amazon Ec2 ?

    Answer :

    In Amazon EC2, we can even bid for getting a computing instance. Any instance procured by bidding is a Spot Instance. Multiple users bid for an EC2 Instance. Once the bid price exceeds the Spot price, the user with the highest bid gets it. As long as their bid price remains higher than the Spot price, they can keep using it.

    Spot price varies with the supply and demand. Once Spot price exceeds Bid price, the instance will be taken back from the user.

Question 46. What Are The Main Features Of Classic Load Balancer In Ec2 ?

If any instance has unhealthy results, CLB will not route the traffic to that instance. Security:  We can create security groups for CLB in Virtual Private Cloud (VPC). With these features, it is easy to implement secure load balancing within a network. High Availability:  With CLB, we can distribute traffic among EC2 instances in single or multiple Availability Zones. This helps in providing very high scale of availability for the incoming traffic. Sticky Sessions:  CLB also supports sticky session by using cookies. The sticky sessions make sure that the traffic from a user is always routed to the same instance so that user gets seamless experience. IPv6:  CLB also support Internet Protocol version 6.

Billing starts when you instantiate an image and stops when you terminate it. Rebooting in between hasn’t any effect.
