Deployments & Managing Infrastructure at Scale in AWS

Question 1

Codestart can be used to monitor and check the health of an environment.
(T or F)

Answer 1

True - Codestar is a unified UI where a dev can manage software development activities in one place.

It’s a quick way to get started with CodeCommit, CodePipeline, CodeBuild, CodeDeploy, Elastic Beanstalk, EC2, etc

Question 2

Which AWS managed service allows to lautomate software deployments to a hybrid mix of EC2 Instances and On-Premises servers?

Answer 2

CodeDeploy - Helps with the transition from on-0prem to Cloud since it works with both.

Question 3

A dev team would like to collaborate on code with versioning support. Which AWS service can help the devs?

Answer 3

CodeCommit - Similar to GIT, but for AWS. Includes Source-control, and hosts git repos. Helps with code collaboration and versioning.
Fully managed and highly available. Private, Secured, and Integrated with AWS.

Question 4

You need a unified user interface that gives you visibility, control, and patching capabilities for your EC2 Instances on AWS and on prem servers. Which service would you use?

Answer 4

System Manager - Requires an agent running on the server, but all EC2 instances have it pre-installed. You’d need to install the agent on your on prem servers and make sure they can communicate with AWS. Can use the agent to run commands, patch and configure servers.

Question 5

You need to use Chef or Puppet. Which AWS service should you use?

Answer 5

OpsWorks - Both of those tools remind me of DevOps, so OpsWorks makes sense.

Question 6

A dev would like to deploy infrastructure on AWS but only knows Python. Which AWS service can help?

Answer 6

Cloud Development Kit (CDK) - Can be written in JavaScript/Typescript, Python, Java and .NET

-The code is “compiled” into a CloudFormation template (JSON/YAML)

-

Question 7

What is the declaration of the AWS resources that make up a stack?

Answer 7

CloudFormation Templates

Question 8

Codestar can orchestrate the different steps to have code automatically pushed to production, while CodePipeline is a unified UT to easily manage software development activities in one place. (True or False)

Answer 8

False

Some of the features offered by AWS CodePipeline are:

Workflow Modeling
AWS Integrations
Pre-Built Plugins

On the other hand, AWS CodeStar provides the following key features:

Start developing on AWS in minutes
Manage software delivery in one place
Work across your team securely

Question 9

Which serverless service can be used to build code and run tests?

Answer 9

CodeBuild - Name is obvious

-Compiles source code, run test, and produces packages that are ready to be deployed (by CodeDeploy for example)

• Fully managed, server less
• Continuously scalable and highly available
• Secure
• Pay-as-you-go pricing - only pay for the build time

Question 10

CloudFormation and Elastic Beanstalk are free to use. (True or False)

Answer 10

True, but you pay for the underlying services.
