AWS Tutorial AWS Solutions Architect and SysOps Administrator - EC2 Instance Types

This lecture covers various EC2 instance types and their configurations, focusing on AWS's infrastructure and the process of creating and managing EC2 instances. It explains vertical scaling, specifically changing instance types from T2 micro to T2 large, and the implications of such changes. A practical demonstration is provided, showing how to log into an EC2 instance, check its resources, and change its type using the AWS Management Console. The lecture also discusses network performance considerations when selecting instance types.

What is allocated to a T2 micro EC2 instance upon creation?

• 2 GB of RAM and 2 virtual processors

• 8 GB of RAM and 8 virtual processors

• 4 GB of RAM and 4 virtual processors

• 1 GB of RAM and 1 virtual processor

What does vertical scaling in AWS EC2 allow you to do?

• Change the operating system of the instance

• Increase the network bandwidth

• Add more storage to the existing instance

• Change the instance type to a larger or smaller one

What happens to the current EC2 instance when you change its type?

• It is upgraded without any downtime

• It is destroyed and a new instance is created

• It is paused and then resumed

• It continues running with the new configuration

During the instance type change process, what happens to client access?

• Clients experience a temporary slowdown

• Clients cannot access the instance as it is shut down

• Clients are redirected to a backup instance

• Clients can still access the instance without interruption

After changing the instance type to T2 large, what is the new RAM allocation?

• 8 GB

• 4 GB

• 2 GB

• 1 GB

What information does the EC2 instance type chart provide?

• The number of virtual processors and memory allocation

• The geographical location of each instance type

• The security features of each instance type

• The cost of each instance type

Why is it important to choose the right EC2 instance type based on network bandwidth?

• To increase the storage capacity

• To avoid legal issues with AWS

• To enhance the security of the instance

• To ensure optimal performance and cost efficiency
