Answer 24

AWS Elastic Beanstalk abstracts the underlying infrastructure and automates the deployment, capacity provisioning, load balancing, scaling, and application health monitoring of your applications making it easy to deploy and scale applications developed in various programming languages.

Question 25

Why use AWS Lightsail?

Answer 25

AWS Lightsail is a simple and cost-effective way to host websites, web applications, or development environments without the complexity of managing and configuring multiple AWS services.

Question 26

What are the advantages and disadvantages of on demand pricing for AWS EC2?

Answer 26

No up front cost, no commitment, pay for what you need, instant scaling.

On demand pricing full cost (most expensive) option for compute.

Question 27

What is the advantage of savings plan pricing for AWS EC2?

Answer 27

Significant cost savings (~70%) if you commit to a specific monthly compute spend for a period of one to three years.

Question 28

What is the advantage of reserved instance pricing for AWS EC2?

Answer 28

Significant cost savings (~75%) if you commit to a specific region and instance type for a period of one to three years.

Question 29

Do reserved instance price plans allow purchaser to change instance type?

Answer 29

A convertible reserved instance contract allows you to change instance types within the region. A standard contract does not.

Question 30

What are the advantage and disadvantages of spot instance pricing for AWS EC2?

Answer 30

Lowest possible cost up to 90% off on demand pricing. However, AWS may interrupt or terminate the instance with a two minute warning.
