MEAN Stack AWS to Azure migration

Question

Hi Team,

My client wants to migrate the MEAN stack application which already hosted in AWS to Azure. This is part of the acquisition plan.

Below are the current AWS details, I have few thoughts on the migration plan which i have highlighted below, Please suggest me the reliable option for this migration 

AngularJS 1.4 - Single VM(A) as AWS
ExpressJS - Single VM(A) as AWS
MongoDB - Azure Cosmos DB

Or 

AngularJS 1.4 - App Service A
ExpressJS - App Service B
MongoDB - Azure Cosmos DB

Tech Stack

1. AngularJS 1.4 - Front End
2. ExpressJS - API
3. MongoDB - Datasource

AWS Tech details

Database Server:
MongoDB 3.4.1 (3 cluster replica set)

Web Server:
● Hosted on AWS
● c4.large instance
● NGINX web server that proxies requests to NODEJS
● NODEJS Server (API)
○ Running express
○ Accepts JSON web tokens validated thru our auth provider Auth0
○ Mongoose ORM is used to interact with MongoDB

Client Application:
● Single Page Application written in Angular 1.4
● Uses SASS styes and bootstrap CSS
● Authentication is hosted via Auth0 and security tokens are issues for AP access
○ Tokens have a 24 hour lifespan
● All routes are handled via Angular

Thanks & Regards,

Arun K

Hey, 

Just a tiny recommendation, StarWind V2V converter can help you doing cross cloud migration. You can convert your AWS instances to Azure directly. https://www.starwindsoftware.com/starwind-v2v-converter

You should choose AWS as a location of your image: 


Choose Azure as destination.
