Kamran Ahmed ee4b7305a2 Adds ByteByteGo guides and links (#106)
This PR adds all the guides from [Visual
Guides](https://bytebytego.com/guides/) section on bytebytego to the
repository with proper links.

- [x] Markdown files for guides and categories are placed inside
`data/guides` and `data/categories`
- [x] Guide links in readme are auto-generated using
`scripts/readme.ts`. Everytime you run the script `npm run
update-readme`, it reads the categories and guides from the above
mentioned folders, generate production links for guides and categories
and populate the table of content in the readme. This ensures that any
future guides and categories will automatically get added to the readme.
- [x] Sorting inside the readme matches the actual category and guides
sorting on production

Airbnbs microservice architecture went through 3 main stages. This post is based on the tech talk by Jessica Tai.
**Monolith** (2008 - 2017)
Airbnb began as a simple marketplace for hosts and guests. This is built in a Ruby on Rails application - the monolith.
**Whats the challenge?**
* Confusing team ownership + unowned code
* Slow deployment
**Microservices** (2017 - 2020)
Microservice aims to solve those challenges. In the microservice architecture, key services include:
* Data fetching service
* Business logic data service
* Write workflow service
* UI aggregation service
* Each service had one owning team
**Whats the challenge?**
Hundreds of services and dependencies were difficult for humans to manage.
**Micro + macroservices** (2020 - present)
This is what Airbnb is working on now. The micro and macroservice hybrid model focuses on the unification of APIs.
