Basically this application demonstrates Azure Active Directory Single Sign-On Authentication, CRUD operations with AWS RDS MySQL, File storage with AWS S3, File download from AWS CloudFront with AWS SDK for .NET with .NET Core, ASP.NET Core MVC, JQuery, Bootstrap, Pomelo.EntityFrameworkCore.MySql.

1. Name: CloudJibe – SnapBox: Personal picture repository
2. Provides Enterprise Level Azure Active Directory Single Sign On Authentication
3. Secure highly available and scalable personal picture storage solution for employees
4. Globally accessible. Individual roles restrict others to see your pictures.
5. Picture metadata is stored in MultiAZ AWS RDS. User data is default populated from Azure AD.
6. System allows jpg and png files to upload of max size of 10 MB.
7. User can browse already uploaded pictures.
8. User can update picture metadata or can replace picture too.
9. User can delete file.
10. System sends notification email on picture deletion using Lambda and SNS topic.
11. System keeps track of picture meta data like First Name, Last Name, Upload time, Updated time, Picture description.
12. System provides list of pictures with link to download.
13. System is deployed in Multi AZ Auto scaling environment.
14. RDS is set to Multi AZ Deployment
15. RDS is maintaining read replicas
16. S3 is set for multi region replication with life cycle as in object storage diagram. Transfer acceleration is enabled for faster file transfer rate.
17. Cloud from is set for caching and faster file downloads at edge locations.
18. CloudWatch Alarm is set with SNS topic email notification on Elastic Beanstalk network traffic crosses threshold traffic.
19. Site is also configured for HTTPs. Secure login using HTTPs

1. Using Azure and AWS cloud platforms.
2. ASP.NET MVC Core (latest open-source and cross-platform framework)
3. JQuery, JSON, Javascript – Client side scripting
4. HTML5
5. CSS3 - Styling
6. Bootstrap – to make responsive UI
7. Bower js web package manager
8. NuGet - Package manager
9. Bundling and minification – To boost performance doing js file bundeling and minification
10. GitHub – For configuration management
11. Pomelo.EntityFrameworkCore.MySql - ORM
12. AWS SDK for .NET Core – To communicate to AWS services.
13. Azure AD – Enterprise user data for authentication
14. Azure AD Federation Authentication – For Single Sign on.
15. Elastic Beanstalk – Used for multi-AZ and auto scale deployment.
16. EC2 – Auto scale “64bit Windows Server 2016 v1.2.0 running IIS 10.0” EC2 instances are used.
17. ELB – used for load balancing
18. Lambda – used to send mail on image deletion.
19. AutoScaling Group – Multi AZ deployment is set for auto scalling
20. Single AZ RDS Db converted to Multi AZ Select InstanceInstance ActionModifyMulti AZ deployment to Yes.
21. CloudFront – caching for faster file download.
22. S3 for object storage
23. S3 Transfer Acceleration
24. R53 – domain registration, URL configuration
25. CloudWatch – log and notification
26. SNS -- Notification
27. IAM – Permissions/role/group

• Visual Studio 2017
• Clone project and open in Visual studio 2017
• Enter your RDS MySQL database connection string in Startup.cs file line # 29.
• Place IAM.json file in root folder where Startup.cs is there. This file will have you AWS profile information. Sample is as follows.

[local-test-profile]
aws_access_key_id=XXXXXXXXXXXXXZX
aws_secret_access_key=YYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
region=us-west-1

• Set up AWS infrastructure
• Setup Azure AD (Will cover in another article for How to)
• Now run your application
• This project is deployed on AWS Elastic Beanstalk on Multi AZ servers with load balancer and autoscaling.

In AWS following 3 are the main technologies which are required to run App. However I used more to make secure, highly available, reliable and scalable application.

1. Create S3 bucket with name as “homework2-manoj”. Enable versioning and transfer acceleration. Lifecycle can be set as architecture diagram to save cost. I also set permissions, user and group in IAM.

var AWS = require('aws-sdk');
var sns = new AWS.SNS();
console.log('Loading function');

exports.handler = (event, context, callback) => {
 var srcBucket = event.Records[0].s3.bucket.name;   
    // Object key may have spaces or unicode non-ASCII characters.
    var srcKey    =
    decodeURIComponent(event.Records[0].s3.object.key.replace(/\+/g, " ")); 
    console.log(
                    'Successfully resized ' + srcBucket + '/' + srcKey 
                );
    
var params = {
  Message: 'CloudJibe portal iniciated filedeletion for file - ' + srcBucket + '/' + srcKey, /* required */
  MessageStructure: 'STRING_VALUE',
  Subject: 'File ('+srcKey+') deleted in S3 from CloudJibe portal',
  TopicArn: 'arn:aws:sns:us-west-1:476374:manojalb_health'
};
sns.publish(params, function(error, data) {
  if (error) console.log(error, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

    //console.log('From SNS:', message);
    callback(null, 'Successfully resized ' + srcBucket + '/' + srcKey);
};

3. Create RSD MySQL database. Run following script to create table.

CREATE TABLE FileUpdate (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
upload_date datetime,
updated_date datetime,
file_name VARCHAR(50),
file_desc VARCHAR(100) 
)
