## title: The sad servers are smiling again

## Introduction
I was bored. I had the idea to look for a stimulating and
challenging platform similar to LeetCode, but focused on
Linux and DevOps.

So I did some research and quickly found SadServers. I then
decided to explore it and try to solve a few problems. This
blog post is simply a brief review of my experience with
SadServers.

In the rest of this blog post, we'll refer to the problems
as scenarios in accordance with the SadServers terminology.

## What is SadServers
It's a web platform that offers scenarios for DevOps
engineers to solve within a time limit. Each scenario is set
up in a dedicated Linux environment accessible remotely via
the SadServers web interface. The goal is to solve the
scenarios and then have the solutions verified.
## My goal
I set myself the goal of solving as many scenarios as
possible until I get tired of it and/or my monthly
subscription expires.
## My experience
In this section, I'll talk about my experience with the
platform.
### Completed scenarios
I was able to complete 122 out of 124 challenges, 31 out of
31 easy, 74 out of 74 medium, and 17 out of 19 hard.
### Time spent
It took me about 3 weeks from start to finish. I recommend
this platform to beginners and professionals who have some
free time and want to challenge themselves. I solved an
average of about 5 scenarios per day for 3 weeks, a little
more on the weekends. It took me an average of 2 to 3 hours
each evening, excluding weekends.
### Topics
I find the topics quite diverse and relevant. Each one is a
set of scenarios that could occur in a professional context,
particularly in a corporate setting, for example, creating
application backups that don't work, a misconfigured
database, containers that can't communicate with each other,
and so on.
My favorite topic is Hack, it's similar to CTF challenges.
For example, the scenario Monaco: Disappearing Trick
literally asks you to find a flag by hacking a web server.

### Difficulty
The difficulty is fairly well balanced between easy, medium,
and hard. I first finished all the easy levels, then tackled
the medium ones, and finally the hard ones. I could really
tell the difficulty increased with each level.
That said, I did find some hard scenarios easier than
certain medium ones, I'm thinking in particular of
Karakorum: WTFIT – What The Fun Is This?, which has a
maximum solve time of 40 minutes but feels much shorter to
me.

### Price
I chose the Pro monthly subscription, which costs $9 per
month. I don't think that's very expensive considering the
content offered. I'm happy with the purchase. As far as I
understand, SadServers pays AWS to be able to deploy a new
VM for each challenge.
However, I probably won't continue paying since I've already
completed 99% of the challenges and not many new ones are
being released. In fact, that's why I don't see the point in
buying an annual subscription. Because in 12 months, you
have more than enough time to solve all the scenarios.
## Conclusion
I really enjoyed SadServers. Thanks to Fernando Duran for
creating and maintaining it, it kept me busy while allowing
me to put my DevOps engineering skills to use. It also
helped me achieve my goal while having fun and challenging
myself. I found it very fun and challenging, these are great
exercises for learning new technical skills and even for
improving your existing ones.
