 In this post, I will show you  how to create S3 bucket,  how to put objects into the bucket,  how to upload multiple objects in s3,  how to download multiple objects,  how to control access policy, and  how to host a static website in S3.  1. How to create S3 Bucket using Python3 Boto3? Object : resource method: create_bucket  important method  parameters:   ACL : private or public   Bucket - name of the bucket name this should be unique for each bucket   CreateBucketConfiguration - have the LocationConstrating that is region on which you want to host your s3 bucket. import boto3 s3_resource = boto3.resource('s3') bucket = s3_resource.create_bucket(ACL='private', Bucket='vybhava2023demo.com', CreateBucketConfiguration={ 'LocationConstrating': 'us-west-2' }) print("Successfully create bucket:", bucket) 2. How to put the objects into the S3 Bucket using Boto3 When you want to add fil...

Hey Welcome! back to Automations with Python for AWS!!  Amazon Elastic Compute Cloud (EC2) is one of the most widely used AWS services for hosting applications and workloads in the cloud. While AWS Management Console provides a user-friendly interface, managing hundreds of EC2 instances manually becomes inefficient and error-prone. Python automation with Boto3 allows organizations to perform instance operations consistently, securely, and at scale. Boto3 is the official AWS SDK for Python that enables developers and DevOps engineers to interact with AWS services through code. It provides APIs for launching, monitoring, stopping, rebooting, and terminating EC2 instances. What are we doing? Have you ever logged into the AWS Console just to start, stop, or reboot EC2 instances and wondered if there was a faster way? As DevOps Engineers, Cloud Administrators, and Automation Architects, we perform repetitive EC2 management tasks every day. Instead of manually navigating through the AW...

The objective of this post is for experimenting with AWS Boto3 automations and AWS Lambda, most of the realtime usecase on AWS cloud controlled and acceleration with them. We should know as SRE or DevOps Engineer how to refer to the Boto3 documentation where AWS team provided lot of details and examples of each Boto3 method, I'm pretty sure you could make great automations with this Boto3 module explore ideas. Python for AWS Using Boto3 Let's jump on it... Prerequisites You must have AWS account [this can be your company provided or free-tire account]. Getting Started Python Automations using Boto3  Step 1: Add User in IAM  Let's get into the IAM adding user you can provide username as devops-admin Select AWS Access TYPE {tic} programmatic access this allows to access key ID and secret access key for the AWS API, CLI SDK (Boto3 uses this). Set permissions for 'devopsuser' Select policy type as 'AdministrationAccess' to access AWS resources and services [For...

 This post is dedicated for all DevOps Engineer, Software Engineers who are preparing for Coding Interviews,  Overview of Coding Interviews Most Companies looking for People with minimum Coding knowledge. In a coding interview, you will be given a small problem to solve within 10 - 20 minutes online screen or in-person on their system. In the question, you might be having some part of the code framed and you might be asked to write a snippet of code in between. You need to understand the code comments and proceed to build the expected snippet of code. Bigger companies look for the General purpose questions, where small companies look for specific questions. The General questions would be like this: Determine if the given word is a palindrome or not. (Example madam) Determine given number is prime or not. How to prepare for a coding interview? Now we have the flexibility to choose the programming language on which you are comfortable.  In general DevOps Infra guys will be ...
