How to share a custom AMI to other accounts

-
Image
Hi everyone 🙂, I am Manshu Sharma and today we are going to discuss an interesting topic that will help us to share custom private AMI in all accounts & regions. In this post first, create a custom encrypted AMI from the public AMI, and then share the custom AMI with encrypted EBS snapshots across accounts and regions. This approach allows you to launch Amazon EC2 instances globally from multiple accounts by using the same base-encrypted AMI. Requirments We need two AWS accounts i.e SourceAccount & DestinationAccount Have a basic knowledge of AWS services SourceAccount:- In which you build a custom AMI and encrypt the associated EBS snapshots. DestinationAccount:- In which you launch instances using the shared custom AMI with encrypted snapshots. Note :- While writing this blog post I am considering two imaginary AWS account ids  111111111111   with region us-east-1 for  SourceAccount & 999999999999   with us-east-1 for DestinationAccount so be sure yo...

Min Steps To 1

-
Given a positive integer 'n', find and return the minimum number of steps that 'n' has to take to get reduced to 1. You can perform any one of the following 3 steps: 1.) Subtract 1 from it. (n = n - ­1) , 2.) If n is divisible by 2, divide by 2.( if n % 2 == 0, then n = n / 2 ) , 3.) If n is divisible by 3, divide by 3. (if n % 3 == 0, then n = n / 3 ). Input format : The first and the only line of input contains an integer value, 'n'. Output format : Print the minimum number of steps. Constraints : 1 <= n <= 10 ^ 6 Time Limit: 1 sec Sample Input 1 : 4 Sample Output 1 : 2 Explanation of Sample Output 1 : For n = 4 Step 1 : n = 4 / 2 = 2 Step 2 : n = 2 / 2 = 1 Sample Input 2 : 7 Sample Output 2 : 3 Explanation of Sample Output 2 : For n = 7 Step 1 : n = 7 ­- 1 = 6 Step 2 : n = 6 / 3 = 2 Step 3 : n = 2 / 2 = 1

Hey everyone,  Tonight I continue my previous post of the complete setup of xwiki. This post is about how to setup  Nginx as a reverse proxy with an SSL certificate. Before moving further we consider that xwiki runs on the server( EC2 server) with a domain name called example.in To create a custom domain name using AWS you can follow this link:-  https://aws.amazon.com/getting-started/hands-on/get-a-domain/ By default, Tomcat 9 works on port 8080 , and you can only visit your XWiki site from the same port. If you want to facilitate visitors' access by removing the port number part, you can install Nginx as a reverse proxy between XWiki and visitors. Step 1, Install Nginx using apt: sudo apt install nginx -y Step 2, Setup Nginx as a reverse proxy by modifying its default site configurations: cd /etc/nginx/sites-available  sudo mv default default.bak  sudo vi default Step 3, Edit the file server {  listen 0.0.0.0:80;  proxy_request_buffering off;...
