# Introduction to Service Mesh
|
||||
|
||||
To understand service mesh, we need a good use case. <br/>
|
||||
We need some service-to-service communication. <br/>
|
||||
A basic microservice architecture will do. <br/>
|
||||
|
||||
## A simple Web UI: videos-web
|
||||
<hr/>
|
||||
<br/>
|
||||
|
||||
Consider `videos-web` <br/>
|
||||
It's an HTML application that lists a bunch of playlists with videos in them.
|
||||
|
||||
```
|
||||
+------------+
|
||||
| videos-web |
|
||||
| |
|
||||
+------------+
|
||||
```
|
||||
<br/>
|
||||
|
||||
## A simple API: playlists-api
|
||||
<hr/>
|
||||
<br/>
|
||||
|
||||
For `videos-web` to get any content, it needs to make a call to `playlists-api`
|
||||
|
||||
```
|
||||
+------------+ +---------------+
|
||||
| videos-web +---->+ playlists-api |
|
||||
| | | |
|
||||
+------------+ +---------------+
|
||||
|
||||
```
|
||||
|
||||
Playlists consist of data like `title`, `description` etc, and a list of `videos`. <br/>
|
||||
Playlists are stored in a database. <br/>
|
||||
`playlists-api` stores its data in a database
|
||||
|
||||
```
|
||||
+------------+ +---------------+ +--------------+
|
||||
| videos-web +---->+ playlists-api +--->+ playlists-db |
|
||||
| | | | | |
|
||||
+------------+ +---------------+ +--------------+
|
||||
|
||||
```
|
||||
|
||||
<br/>
|
||||
|
||||
## A little complexity
|
||||
<hr/>
|
||||
<br/>
|
||||
|
||||
Each playlist item contains only a list of video id's. <br/>
|
||||
A playlist does not have the full metadata of each video. <br/>
|
||||
|
||||
Example `playlist`:
|
||||
```
|
||||
{
|
||||
"id" : "playlist-01",
|
||||
"title": "Cool playlist",
|
||||
"videos" : [ "video-1", "video-x" , "video-b"]
|
||||
}
|
||||
```
|
||||
Take not above `videos: []` is a list of video id's <br/>
|
||||
|
||||
Videos have their own `title` and `description` and other metadata. <br/>
|
||||
|
||||
To get this data, we need a `videos-api` <br/>
|
||||
This `videos-api` has its own database too <br/>
|
||||
|
||||
```
|
||||
+------------+ +-----------+
|
||||
| videos-api +------>+ videos-db |
|
||||
| | | |
|
||||
+------------+ +-----------+
|
||||
```
|
||||
|
||||
For the `playlists-api` to load all the video data, it needs to call `videos-api` for each video ID it has.<br/>
|
||||
<br/>
|
||||
|
||||
## Traffic flow
|
||||
<hr/>
|
||||
<br/>
|
||||
A single `GET` request to the `playlists-api` will get all the playlists
|
||||
from its database with a single DB call <br/>
|
||||
|
||||
For every playlist and every video in each list, a separate `GET` call will be made to the `videos-api` which will
|
||||
retrieve the video metadata from its database. <br/>
|
||||
|
||||
This will result in many network fanouts between `playlists-api` and `videos-api` and many call to its database. <br/>
|
||||
This is intentional to demonstrate a busy network.
|
||||
|
||||
<br/>
|
||||
|
||||
## Full architecture
|
||||
<hr/>
|
||||
<br/>
|
||||
|
||||
```
|
||||
|
||||
+------------+ +---------------+ +--------------+
|
||||
| videos-web +---->+ playlists-api +--->+ playlists-db |
|
||||
| | | | | |
|
||||
+------------+ +-----+---------+ +--------------+
|
||||
|
|
||||
v
|
||||
+-----+------+ +-----------+
|
||||
| videos-api +------>+ videos-db |
|
||||
| | | |
|
||||
+------------+ +-----------+
|
||||
|
||||
```
|
||||
|
||||
## Run the apps
|
||||
|
||||
There is a `docker-compose.yaml` in this directory. <br/>
|
||||
Change your terminal to this folder and run:
|
||||
|
||||
```
|
||||
docker-compose build
|
||||
|
||||
docker-compose up
|
||||
|
||||
```
|
||||
|
||||
You can access the app on `http://localhost`
