Deployments & Managing Infrastructure at Scale Flashcards

1
Q

What is CloudFormation?

A

CloudFormation is a declarative way of outlining your AWS Infra, for any resources.

CloudFormation will auto create resources for you, in the right order, with the exact configs that you specified.

Q

What are the benefits of Cloud Formation?

A

Infrastructure as Code - Resources are not manually created which is great for control.

Predictable Cost - You can estimate costs of resources based on your template. Once created, each resource in the stack is tagged so you can see how much the stack costs.

Savings - You can schedule a stack to be created/deleted in dev to save costs.

Productivity - Ability to destroy/create on the fly

Don’t reinvent the wheel - leverage existing templates and docs

Q

What is Beanstalk?

A

It is a PaaS that allows a developer centric view of deploying applications on AWS.

Uses all the same components of Infra (EC2, ASG, ELB, RDS…), but it’s all in one view that’s easy to make sense of!

You still have a view of all individual components.

Q

What are the three architecture models offered by Beanstalk?

A

Single Instance = for dev
LB + ASG = for prod or pre prod web apps
ASG only = for non web apps in prod

Q

How can you monitor the health of your deployments on Beanstalk?

A

Beanstalk does have a full monitoring suite

A health agent is on each EC2 instance and is pushed to CloudWatch. You can view these metrics in Beanstalk.

Q

What is the difference between Beanstalk and CloudFormation?

A

CloudFormation is used to deploy infra as code (doesn’t have to be an application or EC2).

Beanstalk is a code centric view where you need to upload your code and then Beanstalk will figure out how to run your code. It is more application focused.

18
Q

True or False?

CodeStar can be used to monitor and check the health of an environment.

A

False. CodeStar is used to quickly develop, build, and deploy applications on AWS. Elastic Beanstalk can be used to monitor and to check the health of an environment.

19
Q

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

A

AWS CodeDeploy is a service that automates code deployments to any instance, including Amazon EC2 instances and instances running on-premises.

20
Q

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

A

AWS CodeCommit is a secure, highly scalable, managed source control service that makes it easier for teams to collaborate on code. It also provides software version control.

21
Q

You need a unified user interface that gives you visibility, control, and patching capabilities for your EC2 Instances on AWS, as well as for servers running in your on-premises data centers. Which service should you use?

A

AWS Systems Manager gives you visibility and control of your infrastructure on AWS. It is used for patching systems at scale.

22
Q

24
Q

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

A

AWS CloudFormation templates are JSON or YAML-formatted text files. They are declarations of the AWS resources that make up a stack.

25
Q

Which of the following services can a developer use to store code dependencies?

A

AWS CodeArtifact is a fully managed artifact repository (also called code dependencies) service that makes it easy for organizations of any size to securely store, publish, and share software packages used in their software development process.

26
Q

True or False?

CodeStar can orchestrate the different steps to have code automatically pushed to production, while CodePipeline is a unified UI to easily manage software development activities in one place.

A

False.

AWS CodePipeline is a fully managed continuous delivery service that helps you automate your release pipelines for fast and reliable application and infrastructure updates. CodeStar is used to quickly develop, build, and deploy applications on AWS with a unified user interface.

27
Q

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

A

AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. With CodeBuild, you don’t need to provision, manage, and scale your own build servers, it is serverless.
