CDND-Capstone-Project

This is a repository for the fifth and final project in the AWS Cloud DevOps Engineer Udacity Nanodegree (Capstone Project). The project would deploy a Deep Learning API Microservice to classify input images according to the ImageNet dataset classes.

The objective of the project is as follows:

• Build a web application that serves a pre-trained PyTorch MobileNet-V2 ImageNet Classifier Deep Learning model via a Python Flask application in a Waitress production WSGI server.
• Set up a Docker image that contains the web application and required dependencies which can also load the model to an NVIDIA CUDA GPU if available for faster inference.
• Deploy the Docker image on a Kubernetes cluster using the AWS Elastic Kubernetes Service with the eksctl command line toolkit while leveraging a Jenkins CI/CD Pipeline.
• The Kubernetes cluster would contain two pods with one container each of the Docker image deployed on AWS EC2 t3.large instance nodes with the following Cluster AutoScaler setting: (minimum: one node, desired: two nodes, maximum: two nodes).
• The Kubernetes cluster would be updated via a Rolling Update strategy.

 

• Post-Submission: Changed the Kubernetes cluster configuration to deploy eight pods with one container each of the Docker image deployed on AWS EC2 g4dn.xlarge instance nodes that utilize the Tesla T4 GPU for accelerated machine learning and deep learning inference workloads with the same Cluster Autoscaling setting as before such that the containers would utilize the available GPU resources.

Requirements

• Docker
• kubectl
• aws-cli
• eksctl
