Daily Updates

This is where I’ll be sharing my day-to-day progress as I work through the 100 Days of AWS challenge. Each update will include a summary of what I learned, any obstacles I faced, and key takeaways. Expect to see a mix of technical notes, personal insights, and resources I found helpful.

Day 0 - Onboarding

20th September 2024
Today I spent a little time looking into the various resources available around AWS certification and tried to figure out where exactly I should start. There are quite a lot of certifications and honestly it was a little overwhelming.

I found this video incredibly helpful in breaking down which certification I should start with and roughly what order I should continue. I would highly recommend checking it out.

Ultimately I landed on starting with the AWS Solutions Architect certification and after checking out the free lectures and resources for Adrian’s course I purchased his AWS Certified Solutions Architect - Associate (SAA-C03) course. The course preview can be found here.

I think finding the right course is important. Most courses, especially of this nature need to be relatively long and in depth. Finding the right teaching style that keeps you engaged and motivated while being able to break down those complex topics in a way you can digest is key.

After getting the courses onboarding out of the way, I jumped straight in and started learning about AWS accounts. Notes for this are found in the AWS Fundamental section.

Day 1 - Setting up and configuring accounts

23rd September 2024

Today’s learnings was all about how to setup accounts, setting budgets and enabling MFA. Also explored more meaning behind MFA and what different factors are available.

I have a little more setup to finish tomorrow and then it looks like its onto learning more about Networking and Security.

Day 3 - OSI 7 Layer Networking Model

24th September 2024

Today I switched things up a little bit, the next section of the course recommended taking a free Tech Fundamentals course in order to get a better grasp of topics that will be useful within AWS including:

  • The OSI 7-Layer model

  • Decimal to binary maths

  • Encryption

  • DDOS attacks

  • Layer 7 firewalls,

  • HSMs

  • Hashing

  • Digital Signatures

  • DNS and DNSSEC

  • Containers

  • Backups & and much more.

I completed 13% of this course today and covered the first two layers of the OSI Model. Layer 1 was pretty straight forward, but level two got a little more complicated, so I plan to revist layer 2 tomorrow.

Learning about layer 2 though was super interesting, I had no idea all this was going on under the hood and I am only at the second of 7 layers.
