  • In the previous article, we saw how to deploy a machine learning model into the local box.
  • Now, we will be deploying the model on Amazon EC2.
  • Before doing that, let’s first set up the environment for our trained machine learning model.
  • This can be done using Amazon EC2 through the following steps:

Sign in to AWS Management Console:

  • In order to deploy a model into Amazon EC2, at first, we will have to be familiar with the Amazon Web Services Dashboard.
  • So, sign up and make an AWS account by visiting https://aws.amazon.com/ and clicking on the signup button.
  • For a reference on how to sign up for amazon web services, you can refer to this video.
AWS Sign-in
  • Now after signing in into the AWS accounts and after the validation checks, you will land on the AWS Management Console.

Launch Instances:

Launch Instances for EC2
  • After successful registration, search for EC2 in the search bar and click on Launch Instances.
  • After you have successfully launched the instances, you’ll have to select the machine type.
  • Here, we will be using the free tier which gives us a Linux box with 2GB of RAM hence, we will select the Amazon Linux 2 AMI.
  • After that, you can continue the setup as per the default settings (using a t2.micro instance) and click Review and Launch.
Downloading the key-pair
  • Upon selecting the Launch button you’ll have to select a key pair.
  • You can create your own new key pair.
  • After the successful creation of the key pairs, you can simply download them into your local system. It will be saved as a pem file.
  • Now you’ll have to navigate back to the EC2 instances page the same way by searching EC2 on the search bar.
  • Then click on the instance that you have just launched.
  • After that, click on the Security tab at the bottom of the console and over there you can see a link in the form — sg-0aa552bfee276b14d.
  • On the next page scroll to the bottom and go to Edit Inbound Rules.
  • In the Inbound rules, add an All traffic rule with 0.0.0.0/0 CIDR block and then save.

Setup Putty for Deployment:

  • As for the next course of action, one is supposed to download and install PuTTy as per the default presets.
After successful installation, you should see PuTTYgen on your system
  • Next, one should open PuTTYgen from Windows.
PuTTY Key Generator
  • After that, the pem file needs to get loaded that was downloaded initially.
  • Keep in mind you keep all the files in the same directory otherwise it will challenging to connect to the right EC2 instance in AWS.
  • After the pem file is successfully loaded, one should save the file as a .ppk (for example filename.ppk) format in the same directory of the pem file.

Setup WinSCP:

  • After the setup of Putty, you need to download WinSCP from here.
  • One should keep in mind that at the time of the installation it should be a Typical Installation.
  • The user interface style should be selected as Commander.
  • Now as we open the WinSCP application we can see a hostname needs to be passed.
  • In order to find the hostname go to the EC2 instance, select it and click on connect.
  • After that click on SSH Client.
  • Here, you can find your hostname as ec2–54–198–143–216.compute-1.amazonaws.com.

Please note that you’ll be getting a different hostname from your AWS Management Console.

  • You need to copy the hostname and paste it into the hostname section of WinSCP.
  • After that enter the username and click on Advanced.
  • After that click on authentication and select the three dots in the private key file section.
  • Over there, you’ll have to select the ppk file that was created and click open.
  • After that, click on Login and a popup window should open in front of you. Click on Yes.
  • In case you face any error please do have a look at the username.

Usually, the usernames are ec2-user, ubuntu, centos, root, or admin.

  • You can read about the common error and how to resolve it here.
  • After the connection is established successfully, you’ll have to drag and drop the necessary files.
  • For this project, we have selected app.py, templates, the pickle file, and requirements.txt.

Installation of the required libraries into the server:

  • Now one issue is that, in the server, most of the libraries are not yet installed, and hence, we will have to manually install all the libraries.
  • In order to do so, open Putty.
  • Paste the hostname in the Host Name (or IP address) section.
  • Give a session name, here we have given MLDemoTest as the session name.
  • Next, click on SSH.
  • Next to the SSH button, you’ll find a (+) sign click that and then click on Auth.
  • Click Browse and feed the ppk file.
  • Now go to the session and click on save.
  • After that click on the session name and open it.
  • Now you can see that you’re able to access the terminal of that particular Linux server.
Linux terminal of our EC2 instance
  • You’ll have to pass on the username and you can see yourself logged in to the Linux server.
  • Now use the following command in order to install python 3 into the Linux box.
sudo yum install python3-pip

Conclusion:

  • So far in this article, we covered a high-level overview of how to set up our server into Amazon EC2.
  • We understood the setup of a Linux box.
  • In the next article, we will see how to deploy the trained machine learning model into Amazon EC2.
