<li>Common wisdom is to keep the database on a single node (scaling up) until cost or high availability requirements force you to make it distributed.</li>
<li>Maintainability: Take care of three things during design:
<ul>
<li>Operability: Make it easy for operations teams to keep the system running.</li>
<li>Simplicity: Should be easy to understand the system.</li>
<li>Evolvability: Should be easy to make changes to the system.</li>

Chapter 1: Reliable, Scalable and Maintainable Systems


Hi! I'm Param! This is a place for my personal notes.

My website is https://param.codes, and I write more readable
stuff on my substack: https://newsletter.param.codes.

I've found that taking notes helps me remember things, and it's nice
to look back on information that you processed years ago. I jot down random things, there's no real structure, but some of these
notes could eventually become blog posts.

Some notes you might find interesting:

- [[history.laphams_quarterly.democracy.campaign_finance]]
- [[engineering.being_a_mentor]]
- [[history.china.dynasties]]
- [[history.india.indira_gandhi]]

I also keep notes on books I read [[here|books]].

This is built using [[Dendron|engineering.dendron]] and hosted using
[GitHub Pages](https://github.com/paramsingh/notes).

Get in touch via [Twitter](https://twitter.com/iliekcomputers) or email me at `me [at] param [dot] codes`!
