## System design topics: start here
New to system design?
First, you'll need a basic understanding of common principles, learning about what they are, how they are used, and their pros and cons.
### Step 1: Review the scalability video lecture
[Scalability Lecture at Harvard](https://www.youtube.com/watch?v=-W9F__D3oY4)
* Topics covered:
* Vertical scaling
* Horizontal scaling
* Caching
* Load balancing
* Database replication
* Database partitioning
### Step 2: Review the scalability article
[Scalability](http://www.lecloud.net/tagged/scalability)
* Topics covered:
* [Clones](http://www.lecloud.net/post/7295452622/scalability-for-dummies-part-1-clones)
* [Databases](http://www.lecloud.net/post/7994751381/scalability-for-dummies-part-2-database)
* [Caches](http://www.lecloud.net/post/9246290032/scalability-for-dummies-part-3-cache)
* [Asynchronism](http://www.lecloud.net/post/9699762917/scalability-for-dummies-part-4-asynchronism)
### Next steps
Next, we'll look at high-level trade-offs:
* **Performance** vs **scalability**
* **Latency** vs **throughput**
* **Availability** vs **consistency**
Keep in mind that **everything is a trade-off**.
Then we'll dive into more specific topics such as DNS, CDNs, and load balancers.
