This video covers everything you need to understand the basics of #system_design, examining both practical skills that will help you get a job as well as lower level details to help you get a deeper understanding of the concepts. You will start off by learning why huge companies like Google, Facebook, Microsoft, and others needed to use distributed systems in the 1st place. We'll then look at the pros and cons of distributed systems, how to scale web applications, and then look at the individual components used in system design. Finally we'll end with an interview style system design question by designing Youtube.

System design is the process where different elements of a larger system are designed which includes modules, components and the encompassing architecture. Here is an exclusive System Design full course for beginners. Become an expert in System Design: bit.ly/3yqLiYU

🔹 Purpose of System Design
A good system design organises the program modules in a way that is easy to develop and change. A design technique that is well structured helps software developers to to deal with the size and complexity of the programs.

It is imperative to understand the fundamentals of system design since it is a common topic asked during coding interviews at top tech firms. We at Scaler, bring you a comprehensive full course tutorial on System Design covering important topics ranging from relational data modelling to caching that will help you gain concrete insights.

We cover the following topics in this video 👇🏼

0:00 - Relational Data Modeling
14:20 - Horizontal vs Vertical Scaling
38:06 - Stateless vs Stateful Systems
43:38 - Load Balancing in Stateful Systems
51:12 - Consistent Hashing
55:51 - What is Caching?

What is System Design?
System design is the process of designing the elements of a system such as the architecture, modules and components, the different interfaces of those components and the data that goes through that system. Major tasks performed during the system design process are initialising design definition, establishing design characteristics, assessing alternatives for obtaining system elements and managing the design.

🔹 What is horizontal scaling and vertical scaling?
With vertical scaling (a.k.a. “scaling up”), you're adding more power to your existing machine. In horizontal scaling (a.k.a. “scaling out”), you get the additional resources into your system by adding more machines to your network, sharing the processing and memory workload across multiple devices.

In this video, we shall understand the difference between horizontal scaling and vertical scaling through the example of "Delicious" website. Delicious started as a college project but scaled out to more than 5M users with the concept of horizontal scaling.

What is hashing?
In computer science, consistent hashing is a special kind of hashing technique such that when a hash table is resized, only keys need to be remapped on average where is the number of keys and. is the number of slots. Consistent hashing solves the problem of rehashing by providing a distribution scheme which does not directly depend on the number of servers. In consistent hashing when a server is removed or added then the only keys from that server are relocated.

What is a load balancing?
Load balancers are used to increase capacity and reliability of applications. They improve the overall performance of applications by decreasing the burden on servers associated with managing and maintaining application and network sessions, as well as by performing application-specific tasks.

🔹What is cache?
A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.

I cover the systems design interview in more detail in my program Tech Interview Pro ( techinterviewpro.com/ ) if you are interested in learning more. We also do bi-weekly Live Q&As so have a look.

In this video, we discuss load balancing, CDNs, database replication, sharding, caching layers, database schema and indexes, distributed filesystems, and other ways to scale an application. You don't want to scale your design too early or needlessly, but consider where the bottlenecks are. Sometimes you will need database sharding for instance, while other times you may not need a database at all (ie., if the data does not need to persist to disk). Note: the concepts will differ somewhat for a frontend or mobile systems design, which are more focused on the client-side architecture and software design patterns.

Here are 5 Tips for System Design interviews. They are helpful when preparing for a System Design interview.

1. Don't get into details prematurely

2. Avoid fitting requirements to a set architecture in mind

3. Keep it simple, stupid! Remember to look at the big picture and avoid too many hacks when solving.

4. Have justifications for the points you make. Don't use buzz words or half hearted thoughts in your design.

5. Be aware of the current solutions and tech practices. A lot of solutions can be purchased off the shelf which simplify implementation. You should be able to argue for a custom implementation with it's pros and cons.

Have these on the back of your mind during you interview, and all the best!
Here are three major points evaluated during the interview:
1. Clarity of Thought

a. Express your thoughts in a clear manner.

b. Justify your decisions. Critical reasoning and argument are key to a successful software design.

c. When faced with a problem, use standard approaches to mitigate it. For example, say you are faced with an availability problem. State that replication and partitioning help increase availability in general, and move on to offer a solution.

d. Don’t make points without thinking them through. Half-hearted attempts at solving problems are frowned upon heavily.

2. Know about existing solutions

a. Stay up to date with the current solutions in the market. This includes products and design practices. If NoSQL is being adopted left right and center, you need to be aware of it.

b. Know when to pick a solution vs. building something custom. If you name a product, you should be (generally) aware of the features it provides.

c. Design practices enable you to meet custom requirements. Examples are decoupling systems, load balancing, sticky sessions, etc…

3. Flexibility

a. Switch your targets as the requirements shift. If the interviewer wants to know about one particular part of the system, do it first.

b. Never have a set architecture in mind. We all try to fit requirements to a system, but only after it has been shaped by the initial ones. A rigid attitude creates a brittle architecture. It will break before you do.

c. Take a step back at times to make adjustments to the general architecture. Being focused on one part can narrow our vision and bloat those areas. There will be components which can be extracted out and extended to the rest of the system.

The first video of Software Architecture Introduction Course covering basics and fundamentals principles.

In these series of videos I will be doing a Software Architecture Introduction in a practical way. Many concepts like Architecture patterns like Layered Architecture, Scalability and scalable systems design, Horizontal vs Vertical Scaling, Software Quality and many other topics. In this first video of Software Architecture Course I will be covering the basics and fundamentals topics required to build an eCommerce side. I show what it's like to start a new project and what to look for to avoid pitfalls like overengineering.

This a short course in microcontroller based electronic systems. This course will guide the person from a basic series electronic circuit to a complete microcontroller based control system. This video begins to discuss how the basic series circuit can be analyzed as an electronic system.

Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.

Ps. Have you had the chance to play the Grace Hopper game we made in episode 12. Check it out here! thoughtcafe.ca/hopper/

CORRECTION:
In the pseudocode for selection sort at 3:09, this line:
swap array items at index and smallest
should be:
swap array items at i and smallest
