Udemy Lecture 9: Deploying and Managing Infrastructure At Scale

Question 1

What is cloudformation?

Answer 1

It’s a declarative way of outlining your AWS infrastructure for any resource

Question 2

What is a benefit of cloudformation?

Answer 2

• Infrastructure is code so no resources are manually created, which is good for control n charges to the infrastructure are reviewed through code
• It also supports all AWS resources

Question 3

• Have infrastructure as code
• Need to repeat an architecture in different regions/environment or even different AWS accounts

Answer 3

So for an exam perspective cloudformation will be used when?

Question 4

______________ defines your cloud infrastructure using a familiar language so you can therefore deploy infrastructure and applications runtime code together

Answer 4

AWS cloud development (CDK)

Question 5

What is a 3 tier architecture?

Answer 5

It’s when a client interacts with an ELB and that ELB interacts with auto scaling groups and those interact with elasticache & RDS

Question 6

___________ replaces the web 3 architecture

Answer 6

Beanstalk

Question 7

Beanstalk is also an ______________ service

Answer 7

Platform as a service (PaaS)

Question 8

What is beanstalk responsibility?

Answer 8

• Instance configuration/ OS is handled
• Deployment strategy is configured but performed by elastic beanstalk
• Capacity provisioning
• Load balancer & auto scaling
• Application health-monitoring & responsiveness

Question 9

What is your responsibility related to beanstalk?

Answer 9

• Just the application code

Question 10

Health monitoring

Answer 10

Beanstalk does have ___________ where a health agent pushes metrics to cloudwatch & chefs for all health, publishes health events

Question 11

Answer 13

CodeCommit

Question 14

Git-based repositories

Answer 14

CodeCommit source control service that host ______________ and make it easy to collaborate with others on code and the code changes are automatically versioned

Question 15

_________ allows you to build your code in the cloud, it compiles source code, run tests, and produces packages that are ready to be deployed

Answer 15

CodeBuild

Question 16

__________ orchestrate the different steps to have the code automatically pushes to production(like if u wanted to code—>build—>test—> provision—>deploy)(the basis for CICD -continuous integration & continuous delivery)

Answer 16

CodePipline

Question 17

Software packages depend on each other to be built (also called code dependencies) and new ones are created, storing & retrieving those dependencies is called artifact management and for that you need an artifact management system like __________

Answer 17

CodeArtifact

Question 18

What is CodeArtifact?

Answer 18

It’s a secure, scalable, and cost effective artifact management for software development

Question 19

Answer 21

With codestar can edit the code “in the cloud” using ______

Question 22

___________ is a cloud IDE (integrated development environment) for writing, running and debugging code

Answer 22

Cloud9

Question 23

________ helps you manage your EC2 and On-Premise systems at scale and it’s a hybrid service

Answer 23

System Manager (SSM)

Question 24

• Patching automation for enhanced compliance
• Run commands across an entire fleet of servers
• Store parameter configuration with the SSM store

Answer 24

With SSM you get operational insights about the state of your infrastructure and a suite of 10+ products, what are the most important features of SSM?

Question 25

1. Need to install the SSM agent onto the system we control
2. If an instance can’t be controlled with SSM it’s probably an issue with the SSM agent
3. With the SSM agent we can run commands, patch & configure our servers

Answer 25

How does the SSM work?

Question 26

Answer 26

SSM session manager

Question 27

Answer 27

System manager parameters store
