Happy Birthday Linux

Happy 28th birthday to Linux.

In 1991 the legendary Finnish student Linus Benedict Torvalds created free OS Kernel at the University of Helsinki which is the Linux kernel. 
Torvalds wrote in the comp.os.minix message board: “I’m doing a (free) operating system (just a hobby, won’t be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I’d like any feedback on things people like/dislike in minix, as my OS resembles it somewhat (same physical layout of the file-system (due to practical reasons) among other things),”
According to him, Linux began to gain importance in 1992 after the X Window System was ported to Linux by Orest Zborowski, which allowed Linux to support a GUI for the first time.

AWS Systems Manager or SSM to manage infrastructure

  Hello folks. This is Utpal and in this article, I have discussed  AWS Systems Manager . Please read the entire article. AWS Systems Manager (SSM) is an AWS management tool using which we can manage EC2 instances, On-Premise systems at scale. We can get into the infrastructure state and detect problems. Maximum services in AWS Systems Manager are free. To manage EC2 instances or On-Premise systems we need to install SSM agents on them. They report and communicate with SSM service. For this, we have to give proper IAM permission. There are many services- Session manager, Run command, Patch manager, Maintenance window, Automation, State manager, Parameter store, AppConfig, Change Calendar etc. Here is an example- I have created an IAM role with Amazon managed policy- AmazonEC2RoleforSSM . Then I have launched 3 EC2 instances with Amazon Linux 2 AMI, t2.micro type, and with the just created IAM role. So SSM agents are already installed. Now after they are launched, the...
