Which entity ensures that your application on Amazon EC2 always has the right amount of capacity to handle the current traffic demand?
What is an Amazon EC2 instance?An Amazon EC2 instance is a virtual server in Amazon's Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure. AWS is a comprehensive, evolving cloud computing platform; EC2 is a service that enables business subscribers to run application programs in the computing environment. It can serve as a practically unlimited set of virtual machines (VMs). Show
Amazon provides various types of instances with different configurations of CPU, memory, storage and networking resources to suit user needs. Each type is available in various sizes to address specific workload requirements. Instances are created from Amazon Machine Images (AMI). The machine images are like templates. They are configured with an operating system (OS) and other software, which determine the user's operating environment. Users can select an AMI provided by AWS, the user community or through the AWS Marketplace. Users also can create their own AMIs and share them.
EC2 instance typesInstance types are grouped into families based on target application profiles. These groups include the following:
Amazon EC2 instance featuresMany EC2 instance features are customizable, including the storage, number of virtual processors and memory available to the instance, OS and the AMI on which the instance is based. The following are Amazon EC2 instance features:

What services allows you to automatically scale Amazon EC2 capacity out or based on conditions you define?AWS Auto Scaling monitors your application and automatically adds or removes capacity from your resource groups in real-time as demands change.
How can you ensure high availability of EC2 based application in AWS?Perform detailed monitoring.. Use DNS for load balancing and floating IPs for failover.. Use multiple Availability Zones.. Keep traffic within one Availability Zone and use EC2 placement groups.. Use enhanced networking EC2 instance types.. Which AWS service gives Amazon EC2 the ability to scale compute capacity based on incoming traffic?Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) Cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster.
Which AWS service lets you automatically increase or decrease the compute capacity?Amazon EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define.
