Introduction Deploying applications to the cloud has become a cornerstone of modern software development. AWS offers CloudFormation as a service to facilitate cloud deployments and tools like the AWS Cloud Development Kit (CDK). At the same time, Terraform has emerged as a powerful solution for Infrastructure as Code (IaC), enabling faster deployments to multiple cloud providers. In this article, we’ll explore the benefits of using AWS CDK and Terraform together and walk through a practical example of creating a REST API with CDK in TypeScript. What is Terraform and CDK? Terraform Terraform is a tool created by HashiCorp that allows…

EC2 Snapshot Management: How to get AWS EC2 Snapshot Information with Python

stp2y0 CommentsNewsaws, coding, community, development, engineering, inclusive, python, software

Introduction Amazon Elastic Compute Cloud (EC2) snapshots are integral to data backup and disaster recovery strategies within AWS. They provide point-in-time copies of your EC2 instance volumes, allowing you to restore data quickly and reliably in the event of failures, data loss, or system corruption. As organizations scale their cloud infrastructure, managing these snapshots becomes increasingly complex and time-consuming. Automation is the key to simplifying this process, ensuring data integrity, and optimizing operational efficiency. In this blog post, we'll walk through a Python script that automates the extraction of snapshot information, including associated instance details. This script exports the gathered…

1. Python In-Built LibrariesA Python library is a collection of pre-written code that provides specific functionalities and can be imported and used in other Python programs. A library can contain functions, classes, and modules that can be used by other programs, saving time and effort in development. Python libraries are often created to solve specific problems and make it easier for developers to write code by providing pre-built solutions. They can be open-source or proprietary and can be installed via Python’s package manager, pip. In DevOps, Python libraries can be used to automate tasks, interact with APIs and cloud services,…

AWS offers multiple load-balancing solutions tailored to different use cases within the Elastic Load Balancing (ELB) service. The two primary types are the Application Load Balancer (ALB) and the Network Load Balancer (NLB). Below is a detailed comparison of ALB and NLB, highlighting their features, use cases, and differences. Application Load Balancer (ALB) Key Features: 1. Layer 7 Load Balancing: Operates at the application layer (OSI layer 7), making it capable of routing HTTP/HTTPS traffic. Supports advanced routing features such as host-based, path-based, and query string-based routing. 2. Content-Based Routing: Can route requests to different target groups based on the…
