FAQ

- How is this course different from other System Design or Software Architecture courses?

Many courses teach the fundamental building blocks for system design and software architecture. However, just knowing those building blocks is not enough. Real-life large-scale systems are very complex, and designing them takes practice and experience. This course is all about practice and gaining that experience. So, when you are faced with a real project where you need to apply your software architecture and system design skills, you know exactly what to do and what process to follow.

- Does this course involve coding?

No. This course is on practical software architecture and system design, which is universal and is not tied to a specific programming language, cloud vendor, or technology stack. Throughout the course, you will master the important skill of thinking on a higher-level abstraction, which is critical for success in your company's system design interviews and technical leadership.

- Is this course only for Software Architects?

No. This course is for software engineers on any level who aspire to accelerate their career growth and practice software architecture and system design. This course is also perfect for people with technical leadership positions, such as Senior/Principle/Staff Engineers, Technical Leads, Technical Engineering Managers, or Software Architects, to practice and improve their skills. DevOps engineers, SREs, and QA engineers will also gain a lot of value from this course.

- Will this course cover any Cloud Computing concepts or Cloud Technologies?

Since in this course, we design and architect modern, large-scale systems, we use many cloud computing and distributed computing principles and patterns. Also, while this course doesn't cover any particular cloud vendor or technology, all the software architecture diagrams can easily be implemented and deployed on any cloud vendor, such as Amazon Web Services (AWS), Google Cloud Provider (GCP), Microsoft Azure, and so on. To help you with that, each section contains links and resources to the relevant cloud vendors' services and cloud technologies to help you apply the design to the relevant technology stack. Links to open-source solutions are also provided.

Introduction

Introduction to solving large-scale design problems in software architecture.
Highlights the key concepts necessary that any software architect needs to know to be successful at software architecture and system design
Lays out the step-by-step system design process.

Covers the first 3 steps of the system design process for a scalable image-sharing social media platform. The first step is to gather the system requirements and define the system's API. The lecture then defines the functional and non-functional requirements, including scalability, availability, and performance, before moving on to the API's definition using a sequence diagram.

This lecture discusses the design process for a large-scale image-sharing social media platform, focusing primarily on the functional aspects of the system. The lecture covers the 4th step in the system design process where we

Define the high-level software architecture diagram
Follow the microservices architecture and event-driven architecture to fulfill the functional requirements and the previously defined API

The lecture covers the last step of the system design process to address the scalability, high availability, and performance of the system. Augments the previously defined software architecture diagram with all the necessary software architecture components and building blocks.

Covers the first 3 steps of the design of a highly scalable video streaming platform, which includes capturing the requirements, sequence diagram, and system's API. Using this data, we can later continue the system design process and define the software architecture of the system.

Covers important system design decisions for delivering video streaming services to millions of users on a global scale.

Defines the software architecture of the system, following several software architecture styles such as microservices and software architecture patterns.

Covers the last part of the system design process. In this step of the design, we address the scalability, fault tolerance, and performance of the system to arrive at the final software architecture for a video streaming platform.

This is the first phase of the Software Architecture and System Design of a Real-Time Instant Messaging platform. In this phase, we capture all the requirements and define the system's API.

The lecture first focuses on making some important system design decisions. Then we proceed to design and architect the system using microservices architecture and finish with a software architecture diagram that fulfills the functional requirements.

This lecture addresses the system's nonfunctional requirements, such as scalability, high availability, and performance.

Here we make some important optimizations and add additional software architectural components.

By the end of the lecture, we finish with an end-to-end software architecture diagram for a large-scale, real-time instant messaging platform.

Covers important concepts of big data processing for the software architecture of a typeahead service.
