I had an idea which I wanted to bring to life and apparently, this week is THE week!

This Python script will show the events happened on the day the script is run. Take a look!

As a side note, this is just the first version. I’m counting on my self-motivation and the community on improving this. I hope you find it entertaining and informative!

I’m fetching the events from history.com, so I can pretty much count on it.

A Milestone

Thu, 23 Jan 2020 00:00:00 +0000

Hello people!

It’s been a long long time since we were together and there are reasons for that. I’d like to give you some updates about myself.

#1

Where to start… Okay. On October, I felt like I needed to take AWS Solutions Architect – Professional certificate. Well, at least some sort of certificate which verifies my cloud knowledge. I studied for two straight months and wasn’t even ready on the exam day. You can check my notes here: https://github.com/Hmerac/AWSCSAProNotes

Anyway(somehow!?) I passed the exam and got my certificate. It felt amazing for two days but then the feeling of triumph slowly faded away because I have one more certificate goal which is CKA. I’ll take it some time later, but not now. This was the first reason.

#2

Snapshot Restore versus pg_restore – Time Comparison

Wed, 13 Mar 2019 00:00:00 +0000

Summary

I’ll just cut to the chase here and give detailed analysis immediately after.

The time difference between pg_restoring an 11GB sized PostgreSQL database with 159MB pg_dump file, versus restoring snapshot of its t2.medium RDS Instance:

Analysis

Important note! The time values are subject to change, because it depends on network, other running processes, intermediary EC2 Instance type etc.

pg_restore

I used a t2.medium SSM Bastion Instance to execute PostgreSQL commands. As I’ve mentioned before, provisioning a more powerful EC2 Instance might increase the performance drastically. You can find information about SSM Bastions in this page.

Imagine you have a PostgreSQL database named “XXX”; with 11 GB size. Don’t get distracted with the name, I don’t know why I named it “XXX”; at the first hand, but here we go anyway 🙂

Session Manager - Modern Bastion

Mon, 11 Mar 2019 00:00:00 +0000

Overview

Are you tired of dealing with key pairs? Maybe tired of securing them with KeyPass? Or configuring SSH daemon for ease of use? Don’t worry, Systems Manager - Session Manager is here to save you from all these.

Session Manager is announced on 11 September 2018 with this here. Seriously, I remember being excited like potatoes thrown into hot oil. Because the process for connecting RDS Instances via Bastion Hosts were literal pain in our workplace. All those SSH private keys, security of them, jumping one from another for again, security reasons… All I can say is, it was taking long.
