Development

The project is done using only AWS resources:

• Amplify
• Cognito
• Route53
• Lambda
• DynamoDb
• GraphQl API

Most of the resources were created by using Amplify Cli \ (it automatically creates CloudFormation template that can be modified later)

amplify init
amplify auth (cognito)
amplify storage (s3)
amplify api (graphql and dynamodb)
amplify function (lambda)

S3 settings (Lifecycle management and Acceleration Configuration) were modified in CloudFormation template:

"AccelerateConfiguration" : {
  "AccelerationStatus" : "Enabled"
},
"LifecycleConfiguration": {
   "Rules": [
   {
    "Id": "GlacierRule",
    "Status": "Enabled",
    "ExpirationInDays": "730",
    "Transitions": [
     {
      "TransitionInDays": "75",
      "StorageClass": "STANDARD_IA"},
     {
      "TransitionInDays": "365",
      "StorageClass": "GLACIER"
     }
    ]
   }
  ]
}

Cognito Admin group was also created with CloudFormation template

  # BEGIN USER GROUPS RESOURCES

  UserPoolGroupAdmins:
    Type: 'AWS::Cognito::UserPoolGroup'
    Properties:
      GroupName: Admins
      UserPoolId: !Ref UserPool

As well as custom fields like first and last names:

  Schema:
    ... 
    -
      Name: custom:firstname
      AttributeDataType: String
      Required: false
      Mutable: true
    -
      Name: custom:lastname
      AttributeDataType: String
      Required: false
      Mutable: true
