DevOps Practices

Implementing DevOps principles to streamline development and operations.

AWS (Amazon Web Services)

AWS is a comprehensive cloud computing platform offering a wide range of services including computing power, storage options, networking, and databases. It provides scalable and flexible solutions for businesses of all sizes.

Seamless Integration of Amazon EC2 and S3 for Scalable Cloud Solutions

This project demonstrates the integration of **Amazon EC2** instances with **Amazon S3** storage, allowing for seamless management of cloud resources. AWS EC2 and S3 Integration Architecture

IaC Architecture
  • Amazon EC2: The **Amazon EC2** instances serve as the compute resources, running applications, web servers, and services that require dynamic scaling and high availability. EC2 instances are provisioned within the VPC to ensure proper security and access controls.
  • Amazon S3: **Amazon S3** is used for scalable object storage. It provides durable and highly available storage for storing large datasets, backups, media files, and other unstructured data. S3 is integrated with EC2 instances for efficient data retrieval and storage.
  • Security Groups: Security Groups are configured for both EC2 instances and S3 buckets, defining the allowed inbound and outbound traffic. This ensures that only trusted sources can access the resources, and tight security policies are enforced.
  • IAM Roles and Policies: **AWS Identity and Access Management (IAM)** roles and policies are defined to manage access between EC2 instances, S3, and other AWS resources. These policies ensure the principle of least privilege and secure access control.
  • Data Backup and Storage: **S3** serves as a centralized backup repository for critical application data, with automated scripts running on EC2 instances to regularly back up data to S3, ensuring data durability and recovery in case of failure.

Building Secure and Scalable Networks with Amazon Virtual Private Cloud (VPC)

This project demonstrates how to design and deploy secure, scalable network architectures using **Amazon Virtual Private Cloud (VPC)**. The VPC allows you to isolate cloud resources in a private network, offering enhanced security, custom networking, and greater control over your AWS environment. AWS VPC Architecture

IaC Architecture
  • VPC (Virtual Private Cloud): Amazon **VPC** is used to isolate cloud resources, providing a secure network environment for EC2 instances, databases, and other resources. It helps you define your own network topology, subnets, and route tables to ensure smooth communication between resources while maintaining high security.
  • Subnets and CIDR Blocks: **VPC** allows you to create both **public** and **private subnets**, offering full control over IP address ranges using **CIDR blocks** (Classless Inter-Domain Routing). Public subnets are used for resources that need internet access, while private subnets are designed for internal services like databases.
  • Internet Gateway and NAT Gateway: The VPC setup includes an **Internet Gateway** for outbound access from public subnets and a **NAT Gateway** for outbound internet access from private subnets. This provides controlled access while ensuring security for internal resources.
  • Security Groups **Security Groups** is configured to enforce tight access control policies, ensuring that only authorized traffic can reach the resources within the VPC. Security groups are stateful
