Enterprise Software Development and Microservices Architecture Internship Program

Enterprise Software Development & Microservices Architecture Internship Program: 6-Week Structured Learning and Experience

Introduction

Enterprise software development focuses on building large-scale, secure, and scalable applications that support critical business processes. This internship program equips participants with the skills to develop, deploy, and manage enterprise applications using Java Spring Boot or .NET Core, along with microservices architecture principles. Participants will gain hands-on experience in API development, microservices design, service discovery, cloud deployment, and security—essential skills for modern enterprise software engineers.

The program is designed for developers and software engineers who want to transition into enterprise application development. The final project consolidates all concepts into a real-world microservices-based enterprise application.

Program Highlights

Week 1: Introduction to Enterprise Development & Tools Setup

·      Enterprise Software Concepts: Explore what differentiates enterprise software from standard applications, with case studies on ERP and CRM systems.

·      Development Environment Setup: Install and configure Java (IntelliJ/Eclipse) or .NET (Visual Studio) and run a "Hello World" program.

Week 2: API Development with Spring Boot or .NET Core

·      Building REST APIs: Develop a simple REST API using Spring Boot that returns a greeting message.

·      CRUD Operations: Create an employee management system with database interactions (H2 or SQLite).

Week 3: Microservices Architecture & API Gateway

·      Monolithic vs. Microservices: Understand architectural differences, benefits, and industry examples.

·      Building Microservices: Develop User and Order microservices with REST APIs.

·      Service Discovery: Implement Eureka Server or Consul for dynamic service registration.

·      API Gateway: Configure Spring Cloud Gateway or Ocelot (.NET) for centralized API routing.

Week 4: Deployment, Containerization, and Cloud Integration

·      Dockerizing Microservices: Create Dockerfiles and manage containers using Docker Compose.

·      Kubernetes Basics: Deploy applications to Minikube, understanding Kubernetes architecture.

·      Cloud Deployment: Deploy microservices to AWS EC2, Elastic Beanstalk, or Azure App Services.

Week 5: Security, Logging, and Documentation

·      API Documentation with Swagger: Generate and test microservices endpoints using Swagger/OpenAPI.

·      Centralized Logging: Integrate Logstash, Elasticsearch, and Kibana (ELK Stack) for log management.

·      Securing Microservices: Implement JWT authentication for secure API access.

Week 6: Final Project – Enterprise Microservices System

·      Enterprise Project: Develop a mini-inventory, HR, or e-commerce system with at least three microservices.

·      End-to-End Deployment: Implement CI/CD, Docker, Kubernetes, and cloud hosting.

·      Deliverables: Source code, architecture diagram, deployment guide, and a 2-3 min demo video.

Expected Outcomes

By the end of this internship, participants will:

·      Understand enterprise software principles and key challenges.

·      Develop REST APIs using Spring Boot or .NET Core.

·      Implement microservices architecture with service discovery and API gateways.

·      Deploy and manage microservices using Docker & Kubernetes.

·      Integrate cloud services (AWS, Azure, or GCP) for enterprise applications.

·      Enhance security using JWT authentication and log analysis with ELK Stack.

·      Complete a real-world enterprise project, demonstrating end-to-end microservices development.
