AWS Interview Questions and Answers Based upon AWS EC2 Instance

What is AWS?

AWS (Amazon Web Services) is a comprehensive, evolving cloud computing platform provided by Amazon that includes a mixture of infrastructure as a service, platform as a service, and packaged software as a service offering. AWS services can offer an organization tools such as compute power, database storage, and content delivery services.

What is AWS EC2?

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment.

What are the features of AWS EC2 Instances?

• Amazon EC2 provides the ability to place instances in multiple locations. Amazon EC2 locations are composed of Regions and Availability Zones. Availability Zones are distinct locations that are engineered to be insulated from failures in other Availability Zones and provide inexpensive, low latency network connectivity to other Availability Zones in the same region. By launching instances in separate Availability Zones, you can protect your applications from the failure of a single location
• You only pay for what you use. It takes the cost of unused minutes and seconds in an hour off of the bill, so you can focus on improving your applications instead of maximizing usage to the hour.
• Different Amazon EC2 workloads can have vastly different storage requirements. Beyond the built-in instance storage, we also offer Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS) to suit other cloud storage workload requirements. Amazon EBS provides persistent, highly available, consistent, low-latency block storage volumes for use with Amazon EC2 instances, while Amazon EFS provides simple, scalable, persistent, fully managed cloud file storage for shared access.
• Enhanced Networking enables you to get significantly higher packet per second (PPS) performance, lower network jitter, and lower latencies. This feature uses a network virtualization stack that provides higher I/O performance and lowers CPU utilization compared to traditional implementations.
