Ques. 9): What is the
relationship between AWS Amplify hosting and Amplify's open source framework?
Answer:
AWS Amplify is a set of
tools (including an open source framework and a graphical programming
environment) as well as a fully managed web hosting solution. The framework's
tools (libraries, UI components, and the CLI), as well as Amplify Studio, the
console, and the static web hosting service, can all be used together or
separately.
You can utilise the AWS
dashboard to deploy and host Single Page App (SPA) frontends and static
webpages, regardless of whether they require Amplify libraries.
AWS Amplify's static web
hosting service provides additional capabilities if you're using the Amplify
CLI to configure backend resources for your app. Before deploying your front
end, AWS Amplify prepares or upgrades these backend resources on each check-in.
When you utilise AWS Amplify's web hosting service, you may create a range of
options, such as isolated backend deployments per branch or shared backend
deployments across branches.

Ques. 10): What elements
of Amplify work with AWS cloud services?
Answer:
Offline data, multi
factor authentication, analytics, and other Amplify features are organised
based on the use cases you need to integrate with your app. The appropriate AWS
cloud services are provisioned for you when you configure these features using
the Amplify CLI or the Amplify Studio. The setup is saved in CloudFormation
templates, which can be shared with other developers and checked into source
control. When you use the Amplify libraries to add these functionalities to
your app, the library makes the appropriate calls to AWS services. 'Amplify add
analytics,' for example, will set up Amazon Pinpoint. Then, when you utilise
the Amplify library's Analytics APIs in your app, the necessary calls will be
made to Pinpoint.

Cloud Support Engineer Interview Question and Answers
Ques. 11): What is the
best way to get started with AWS Amplify web hosting?
Answer:
To get started, go to
the AWS interface and connect your source repository to AWS Amplify. AWS
Amplify detects the front-end framework and develops and delivers the app to a
globally available content delivery network (CDN). Amplify can detect backend
functionality introduced using the Amplify CLI or Amplify Studio and deploy the
relevant AWS resources with the front end. AWS Amplify will instantly develop
and deploy your web app, as well as host it on a global content delivery
network (CDN) with a friendly URL (for example, https://master.appname.amplifyapp.com).
Go to AWS Amplify in the AWS console to get started.

Questions and Answers
Ques. 12): What is the
difference between the Amplify Studio and the Amplify console?
Answer:
Within the AWS
administration dashboard, the Amplify console serves as the command centre for
your app. The AWS Amplify console displays all of the front-end and backend
environments for your apps, whereas Amplify Studio has a separate instance for
each backend environment.
The Amplify interface is
where you can set up web hosting, full-stack CI/CD, add a custom domain,
clone/delete multiple backend environments, and go to underlying AWS service
consoles with AWS Amplify's fully managed web hosting solution. Amplify Studio,
on the other hand, is used to configure and maintain the app backend, including
adding features like authentication, data, and functions. After launching your
app, the Amplify Studio also gives non-developers (QA, PMs) a way to manage app
content and users.

Ques. 14): What kinds of
web applications can I create and deploy?
Answer:
AWS Amplify offers a
fully managed static web hosting solution for web apps and static webpages that
can be accessed directly from the AWS dashboard, in addition to its development
tools and capabilities. The static web hosting service from AWS Amplify offers
a complete workflow for developing, deploying, and hosting single-page web apps
or static webpages with serverless backends. Continuous deployment allows
developers to push updates to their web project with every Git commit. The app
is deployed and hosted on an amplifyapp.com subdomain after the build is
complete. To begin getting production traffic, developers can connect their
custom domain.

and Answers
Ques. 15): What is the
purpose of Amplify Studio being outside of the AWS console?
Answer:
Amplify Studio is
available outside of the AWS console to allow front-end developers who are new
to AWS to interact with AWS products more quickly and efficiently. Amplify
Studio simplifies the elements required to create a cloud-connected online or
mobile app, including both the backend and frontend user interface.
Non-developers (QA testers, PMs) may manage the app's content and users with
ease, without requiring developers to figure out the appropriate IAM roles and
policies.
AWS ActiveMQ Interview Questions and
Answers
Ques. 16): What is a
'app' in AWS Amplify?
Answer:
Your project container
is an AWS Amplify 'app.' A list of branches you've connected from your source
repository is included in each app project. From your app project, you may
connect extra feature branches, a custom domain, and view your build logs.
Ques. 17): What do you
understand by continuous deployment?
Answer:
Continuous deployment is
a DevOps method for software releases in which each code commit to a repository
is pushed to production or staging automatically. By guaranteeing that your
hosted web app is constantly a representation of the latest code in your
repository, this approach lowers time to market.
Ques. 18): Do my Git
access tokens get stored by AWS Amplify web hosting?
Answer:
Access tokens from
repositories are never stored by AWS Amplify. We obtain an access token from
your source provider after you approve AWS Amplify. We simply provide the token
to our console, and all subsequent interactions with the GitHub API is done
entirely through the browser. The token is permanently deleted after
configuring continuous deployment.
Ques. 19): What are the
different types of environmental variables? What am I going to do with them?
Answer:
Environment variables
are runtime configurations that apps require. Database connection information,
third-party API keys, and various customisation settings and secrets are all
possible options. The best approach to make these settings visible is to use
environment variables. When building an app or in the app settings, you can add
environment variables. To prevent unauthorised access, all environment
variables are encrypted. Fill in the key and value textboxes with all of your
app's environment variables. When you connect a new branch to AWS Amplify, the
environment variables are automatically applied across all branches, so you
don't have to re-enter them. After you've entered all of the variables, click
Save.
Ques. 20): What happens
when you run a build?
Answer:
AWS Amplify will build a temporary compute container (4 vCPU, 7 GB RAM), download the source code, execute the project's commands, deploy the created artefact to a web hosting environment, and then destroy the compute container. AWS Amplify will send the build output to the service console during the build.
