🦩Flamingo Home Assignment - DevOps Engineer

We’d like to get a sense of how you approach cloud infrastructure, containerization, and deployment automation. This assignment is not tied to Flamingo’s domain; feel free to use any lightweight setup or example application that makes it easier for you to demonstrate your skills. 📌 Practical Part

Objective

Package and deploy FleetDM to a local Kubernetes cluster using Helm.

1. Helm Chart

Create a public Helm chart that deploys:

FleetDM Server
MySQL
Redis

2. Local cluster

Include a Makefile with the following targets:

make cluster — create local cluster (Minikube or Kind)
make install — install the Helm chart
make uninstall — remove all deployed resources

3. Documentation

Provide a README.md that includes:

Installation & teardown instructions
Verification steps to confirm FleetDM, MySQL, and Redis are operational

4. Enhancements

Set up a basic CI pipeline to release new Helm chart versions.
Expose the FleetDM UI and ensure that FleetDM is reachable by agents
Automatically run fleet prepare db on fresh install

📌 Theoretical Part Architectural Design Document for “Company Inc.”

Objective

A 1–2 page, well-structured architectural design document (PDF or similar).
A High-Level Diagram (HLD) of the architecture (using draw.io, Lucidchart, etc.) illustrating the overall infrastructure design.

Task Overview

Company Inc. is a small startup developing a web application and planning to deploy it on a major cloud provider (AWS or GCP). They have limited cloud experience and seek expertise to design a robust, scalable, secure, and cost-effective infrastructure. They are particularly interested in leveraging managed Kubernetes and following best practices.

Application Details

Type: Web application with a REST API backend and a single-page application (SPA) frontend.
Technology Stack: Backend: Python/Flask; Frontend: React; Database: MongoDB.
Traffic: Initially low (a few hundred users/day), but expected to grow rapidly to millions of users.
Data: Sensitive user data is handled, requiring strong security measures.
Deployment Frequency: Continuous Integration and Continuous Delivery (CI/CD) is required.

Assignment Requirements

1. Cloud Environment Structure

Recommend the optimal number and purpose of AWS accounts / GCP projects for Innovate Inc., considering best practices for isolation, billing, and management.
Justify the choice of provider and the environmental structure.

2. Network Design

Design the Virtual Private Cloud (VPC) architecture.
Describe how the network will be secured (firewalls, security groups, private/public subnets, etc.).

3. Compute Platform

Detail how managed Kubernetes Service (EKS for AWS / GKE for GCP) will be leveraged to deploy and manage the application.
Describe the approach to node groups, scaling policies (horizontal & vertical), and resource allocation within the cluster.
Explain the containerization strategy, including:
- Image building process
- Container registry management
- Deployment pipelines (CI/CD integration)

4. Database

Recommend the appropriate managed MongoDB service and justify the choice.
Outline the approach to:
- Automated backups
- High availability (multi-AZ/replicas)
- Disaster recovery strategy

We value your time and want to gain a clear understanding of how you approach DevOps tasks in a clean, thoughtful, and structured manner.

Good luck, and happy deploying! 🦩
