Cloud Hosting & DevOps Projects

Course Overview
An application needs more than working code to become a dependable hosted service. It needs an environment, a reachable address, correct configuration and a way to verify that each part is running. This course brings together website-hosting lessons, selected AWS and Azure labs, and DevOps tool exercises. The focus is on understanding the relationship between an application, its hosting platform and the tools used to deploy or reproduce its infrastructure. It is intended for learners who already have basic application-development and command-line experience.

Begin with the hosting path. Study connecting a domain to a Linux server, deploying applications in Linux and Windows IIS environments, static website hosting on S3, HTTPS setup and a server troubleshooting example. The recordings use different application stacks, including Spring Boot and React/Node. Treat these as alternative deployment tracks. First reproduce the track that matches your existing application, then compare the configuration and verification steps used by another stack.

Move to the AWS application labs to examine the roles of services such as S3, CloudFront, Lambda, CloudWatch, Amplify, DynamoDB and selected language-analysis services. Follow how the application interacts with storage, authentication, a database or an event-triggered function in the demonstrated projects. The Azure section adds application publishing, GitHub-based deployment, database migration and AI-service examples. The purpose is to trace the participating services and their responsibilities, rather than memorise console clicks.

The DevOps stage introduces a local Kubernetes toolchain, container-oriented application examples, an AWS EKS deployment and Jenkins setup. Continue with Terraform concepts and Azure infrastructure examples involving a virtual machine and a hub-and-spoke network. Written guides explain the distinction between building an application, running a container, exposing a service and provisioning infrastructure. They also introduce repeatable configuration, state, verification and how to record a change so that another learner can reproduce it.

Practise with one small application throughout the course whenever the recording and platform permit it. Keep an environment inventory containing resource names, versions, endpoints and the purpose of each component. For each lab, write down a success check and a failure case before making changes. The final assignment asks you to document a working deployment, demonstrate an update or automation step and explain how the lab resources will be removed.

The 28 recordings are presented by Gaurav Kumar Jain. This is a guided hosting and infrastructure project course, with multiple platform and application examples. It is not a full beginner course in Linux, programming, every cloud service or the complete DevOps profession. Some projects require provider accounts, suitable account permissions and separately billed resources. Consult the current service interface and dependency requirements when reproducing older recordings, and include resource cleanup in the completion of every lab.

Module Overview
Identify the application stack and hosting environment used by this lesson before reproducing it. A Spring Boot application and a React/Node application have different build and runtime requirements. Trace the path from a domain or endpoint to the running application. Record the application process, listening port and required configuration. Confirm success with an actual request and use the relevant process or server logs to explain a failure.

Lesson Overview: Setting Up Hostinger Domain to Ubuntu/Linux Server: Step-by-Step Guide
Trace how a domain name leads a browser request to the intended hosting environment. Distinguish a DNS record, server address and application listening endpoint. Understand the purpose of each configuration value before copying it into another environment.

Practice Task
Draw the route from a fictional domain to a lab server and application. Record the values that are specific to your environment and a check for name resolution and the final response. If you reproduce the lesson, confirm both steps and record where a failed request stops.

What to Check
Verify the relevant endpoint, workload, log or resource result. Record the environment, the change made and the cleanup path, so that another learner can reproduce the lab.

Getting Started
Begin with a small application that runs locally and that you understand well enough to test. Keep its dependencies and required environment variables documented. Use a separate lab account or project where possible, and confirm the active region, subscription and command-line context before a deployment. The course fee does not include cloud-provider usage, domains or third-party services. Set an appropriate lab budget and review how each resource is removed. Keep credentials in the platform's supported configuration mechanism rather than in a public repository. For container exercises, confirm that the machine can run the required local tools. Check the versions used by the recording and choose a compatible environment. Run one minimal service first, verify its endpoint and logs, and only then add more components. Keep a local copy of deployment files and a resource inventory for every exercise.

What to Check
Verify the relevant endpoint, workload, log or resource result. Record the environment, the change made and the cleanup path, so that another learner can reproduce the lab.

Learning Roadmap
Start with a hosting track matching your application stack, then work through the AWS and Azure project sections. Record the purpose and dependency of each service in a simple request-flow diagram. Inspect logs and error messages at the component that owns the failure instead of changing several settings at once. Continue with containers and Kubernetes after understanding a basic application process and network endpoint. Separate Jenkins installation from the design and testing of an actual pipeline. Before applying Terraform, identify the resources described by the configuration, inspect the proposed changes and understand where state is kept. Save a working baseline before modifying an environment. A complete lab record includes setup, the application check, the change made, its observed effect and cleanup instructions.

Final Project and Completion Guide
Choose one application and one suitable deployment track from the course. Produce a working lab deployment with a clear endpoint and a short component diagram. Record configuration requirements, dependency versions and the commands or console actions needed to reproduce it. Demonstrate one update, container deployment or Terraform-based infrastructure change suited to your selected track. Verify both a normal application request and a controlled failure such as missing configuration or an unavailable backend. Include the relevant log evidence and explain the fix. Submit the deployment files, a concise operating guide, a resource inventory and a cleanup procedure. Assess reproducibility, correct application behavior, understandable service responsibilities and the ability to explain an automation or infrastructure step. The assignment demonstrates the selected hosting and lab skills rather than professional certification in every named platform.
