Ques. 5): What is a deployment group?

Answer:

The AWS CodeDeploy entity for grouping EC2 instances or AWS Lambda functions in a CodeDeploy deployment is called a deployment group. You target a set of instances connected to an application while using EC2 for deployments. By naming an Auto Scaling group, a tag, or both, you can add instances to a deployment group. In an Amazon Lambda deployment, a deployment group specifies a set of AWS CodeDeploy configurations, such as alarms and rollbacks, for upcoming serverless Lambda deployment to the group.

An application can have numerous deployment groups, such as staging and production. See Dealing with Amazon EC2 Tags in the Console for more details on tags.

Ques. 8): How does Auto Scaling integrate with AWS CodeDeploy?

Answer:

To guarantee that freshly started instances always receive the most recent version of your application, you can join an Auto Scaling group with a deployment group. Each time an Amazon EC2 instance for that Auto Scaling group is launched, it is first placed in a Pending state before the deployment of the most recent successful revision for that deployment group is triggered on that Amazon EC2 instance. The Amazon EC2 instance's state is updated to InService if the deployment is successful. A new Amazon EC2 instance is launched in the Pending state and a deployment is initiated for the newly launched EC2 instance if the deployment fails.

Ques. 13): What is a deployment configuration?

Answer:

A deployment configuration outlines the actions that should be taken during deployment, including how to deal with failure, through the use of a deployment group. To deploy with zero downtime to multi-instance deployment groups, you can utilise a deployment configuration. You can define this in your deployment configuration, for instance, if your application requires at least 50% of the instances in a deployment group to be active and handling traffic, preventing downtime from a deployment. Amazon CodeDeploy will deploy to one instance at a time by default if no deployment setting is linked to either the deployment or the deployment group.

Ques. 18): What is an AppSpec file?

Answer:

An AppSpec file is a configuration file that details the scripts to run and the files to copy. You place the YAML-formatted AppSpec file in the root directory of your revision. The AppSpec file has two sections and is used by the Amazon CodeDeploy Agent. The source files in your revision that will be copied as well as the final destination folder are specified in the files section for each instance. The location of the scripts to run during each stage of the deployment is specified in the hooks section as relative paths beginning at the revision bundle's root. A deployment lifecycle event is the name given to each stage of a deployment.

Ques. 20): How can I restore a previously revised application?

Answer:

You only need to deploy the prior revision in order to roll back an application to it. There is no distinction between redeploy and roll back because AWS CodeDeploy keeps track of the files that were copied for the current version and deletes them before beginning a new deployment. You must, however, confirm that it is possible to roll back the prior updates.

Ques. 11): You alter my app, right?

Answer:

On iOS, we resign the app and swap out the embedded provisioning profile with a wildcard profile. If you give us the information, we will include auxiliary data in the application package before installation so that it is available in the sandbox for your programme. Some rights are removed when the iOS app is resigned. Related Domains, Game Center, HealthKit, HomeKit, Wireless Accessory Setup, In-App Purchasing, Inter-App Audio, Apple Pay, Push Notifications, and VPN Configuration & Control are included in this.

We shut off the Android app. Functionality that rely on the app signature, such the Google Maps Android API, may be broken as a result. Additionally, it might activate anti-tampering and anti-piracy features offered by goods like DexGuard. For built-in tests, we may modify the manifest to include permissions required to capture and save screenshots.

Ques. 19): How do device slots and the unmetered plan work?

Answer:

Unlimited testing and remote access are available with unmetered options starting at $250 per month. Unmetered prices start at $250 per slot per month and depend on how many device slots you buy for each usage category (such as automated testing or remote access) and device family (such as Android or iOS). Concurrency is corresponding to device slots.

Device Farm will conduct your tests on up to ten devices at a time until all tests are finished on your chosen devices, for example, if you buy ten automated test Android device slots and arrange a run on 100 Android smartphones. You may obtain your findings more quickly if you bought additional slots. You are charged a set fee of $250 per device slot per month, regardless of how many tests or remote access sessions you have. Your membership for one or more device slots can be cancelled at any time, and the cancellation will take effect on the date of your subsequent renewal (the day of the month that you purchased your first active device slot). Through the Amazon Device Farm UI, AWS Command Line Interface (AWS CLI), or AWS Device Farm API, you can buy slots.
