Code Level access, I am providing the Github link - you can clone it from there itself. If you like my article please follow me on my GitHub, If you are having any doubts - watch my youtube video.
AWS Lambda - Once My code is ready, then I am deploying this javascript function as a lambda from AWS, and triggered each and every 2 hours. Why as a Lambda? Because - AWS Lambda is a serverless concept. There is no downtime. Also, I don't have to pay any extra amount to AWS. I only pay, what I consume. For me, it's very cheap, monthly 0.15 dollars. Or less. More details watch my youtube video, below -
Continuous Integration is a process in which all the development work will be integration as early as possible. The resulting artefacts are automatically created and tested. In this blog will help you the continues integration Jenkins with Slack and Email Notification, In order to notify developer each and every build on the slack channel and also if any build failed you will be notified in your mail.
Jenkins CI With Slack And Email Notification
1. Introduction
Jenkins is an open-source continuous integration software tool which is written in Java for testing & reporting the isolated changes in larger code basis in real-time project. This is the software that enable developer to find the defects and solve it rapidly via automation testing.

Amazon EC2 is one of the most used and most basic services in Amazons so it makes sense to start with EC2 when you are new to AWS. But the first question is that what is EC2 in AWS ?
AMAZON EC2 HOSTING MEAN STACK APPLICATION
1. What is EC2 in AWS ?
Well to be very simple,
It's basically virtual machine which includes CPU, RAM, ROM e.t.c
It also allows to choose different platform ( like windows, linux, ubuntu e.t.c ) while you are launching virtual machine in cloud.
The Virtual machine we called it as an instance, you can easily start, stop or terminate your instance.
2. AWS EC2 Mean Stack Application Screens?
I am sharing few screens about out Mean Stack Applications that we are going to host it in AWS EC2.

Mean Stack CRUD Application Delete
3. Architecture of the Mean Stack Application
In the below diagram, this is the architecture of our mean stack application that we are going to setting up in 2 AWS instance. In the FrontEnd Part I am using Angular 6, and
MEAN STACK APPLICATION ARCHITECTURE
whatever user interaction got happened like create, read, write and delete it's happening from Node JS. So Node Js is act as a mediator which helps to talk to my database mongo DB and get back the data to frontend. So we will be going to use 2 instance 1 for frontend and 1 for backend.
3. AWS EC2 Hosting Mean Stack Application using PM2 -
This is the other ubuntu Instance that we are launching it. First thing we need to install Node JS, Angular 6, NVM and PM2 in the AWS EC2 instance. Then we have to clone the code inside the EC2 instance.
git clone https://atique12@bitbucket.org/atique12/mongocrud_application_back_end.git Then edit the file - Mean Stack BackEnd Project - db.js and index.js - Instead of Localhost put first instance mongo DB EC2 Public ip to db.js and 2nd instance public ip to 2nd EC2 instance. Mean Stack FrontEnd Project - Inside src/app/shared vi person.services.ts Change localhost to 2nd AWS EC@ public ip. You can also Visit my youtube video for more details -
