Learning about Site Reliability Engineering with the #100daysofSRE Challenge
I will post something I have learned almost each and every day until the 100 days of the challenge ends. #SRE #100daysofSRE
I will join as a Site Reliability Engineer intern in a company during the summer of 2023. I have previous skills and experience in Sysadmin and DevOps roles and responsibilities. However, even though SRE is similar in some ways, I found there are also some key differences as well.
And, there are very few resources that actually cover the topics and aspects of an SRE role. So, I devised a solution to add value by going through some aspects while learning more about it.
There are a lot of challenges like #100daysofcodes, #100daysofsecurity, and others. I really like this plan for two reasons: first, I will be obliged to complete the challenge; second, it will add some value to myself as well as to the community.
So, today, I asked chatGPT to give me a topic plan for the next 100 days. And here is the list of 100 topics I will cover for the next 100 days. Since I want to avoid flooding Medium with this long challenge, I will keep publishing posts on my own blog and adding the links here to the items on the list so that you can navigate the posts. I will post a weekly summary on Medium, though!
Update: I find many of the suggestions from chatGPT have overlapping issues. So, I decided to skip those overlapping topics (also, some can be merged into one), and I will add more technical content on the way. For now, I am adding TBA at the end.
You can also find the contents in this GitHub repository.
