This course intends to prepare you for system design interviews while also discussing how you may apply this knowledge on the job. Most engineers do not get to create new systems very often in the real world. Some are not allowed to create them at all. Architecture is something that just a few people perform on a regular basis in many businesses. However, when it comes to interviews, suddenly expect everyone to be a system design expert. This course attempts to cover some of the fundamental subjects while also providing their approach to some of the most typical system design interview questions.

The second goal of this course is to equip senior engineers with a different perspective on system design. What they notice in the industry is that they don't talk about design often. It becomes a touchy subject since no real-world design is flawless. That is something they intend to fix.

They recommend two methods for consuming the course. If you have lots of time, just watch it from beginning to end. They attempted to arrange things in a reasonable way so that you would gain confidence as you progressed. If you're short on time or aren't actively preparing for interviews right now, you may start with the design videos, and if you're unfamiliar with one of the issues they mention, there should be either a video or a link to a related article.

The purpose of a system design interview is typically to cover a wide range of subjects. It assesses the breadth of knowledge first, then the depth of knowledge. As a result, they attempted to make the theoretical portion of each issue as concise as possible. That is, it is as in-depth as they as an interviewer anticipate from their prospects. Finally, they will reiterate that no design is flawless. There are always sacrifices and concessions that must be made. And each design is unique. It all relies on your areas of competence. Please regard their films as a collection of ideas for how to approach the issue rather than the definitive method they would construct a system.

Who this course is for:

• Software engineers of all levels preparing for System Design interviews
• Senior engineers that are looking to make the next step in their career
• Software architects that are looking to broaden their knowledge

Requirements:

• Computer hardware basics

The selection of technology is a critical component of system design. Once an architect has identified the system's components, he or she must choose a technology for each component. This course will assist aspiring architects in selecting the best technology for each component. This course is divided into the following sections:

Database choices - You describe the architectural differences between SQL and NoSQL technologies, as well as the circumstances in which each should be employed. You also discuss specialized databases that deal with certain cases, such as text search, compound search, and persistent data structures. You create a decision framework that takes into account all of these factors in order to choose the best database for each case.

Data warehouses and data lakes - You discuss why the OLAP queries conducted by data warehouses necessitate a basic data layout design. You cover the construction of data lakes and warehouses and present a reference architecture. You also talk about the Event Hub pattern, which is becoming increasingly popular in current platforms.

Computing platform selection and cache design - In this topic, you discuss the tradeoffs associated with different compute platforms and how an architect should make the decision. You also examine the requirement for caching and the factors to consider while creating a caching solution.

Who this course is for:

• Developers who want to learn system design and up-level to principal engineer/architect

Requirements:

• Some programming experience is needed
• Ideally, you should have taken the functional design course or have good experience on functional design

In their system design interviews, almost all firms request the design of numerous systems. The system design round is mostly for experienced individuals, although prominent corporations such as Google, Facebook, Microsoft, Amazon, and others are eager to solicit concepts from even freshers. There is a one-to-two-hour round for system design. The system design round serves several functions. The interviewer wants to know your depth of knowledge, how you tackle an open-ended challenge, and how you handle difficult conditions.

High Level Design is another name for System Design. High-level design is nothing more than choosing what components they will need in their system, how those components will communicate with one another and with external systems, and what their system's capacity will be. These are critical considerations when developing any system to ensure its dependability, availability, consistency, and efficiency.

This course is developed in a gradual manner with the aim of comprehension. Initially, all system design concepts and components are considered. A full proven step-by-step process is presented to solve any system design difficulty. All of the case studies are described in detail and are created using these techniques.

Who this course is for:

• Software Engineers

In an interview, software engineering candidates are evaluated on their coding and software design skills. These are dubbed the algorithm and design rounds, respectively. The Algorithms round assesses a candidate's raw coding skills through the use of data structures and algorithms often taught in school, whereas the design round assesses system design skills, which can be High Level Design [HLD] or Low Level Design [LLD].

Object-Oriented Design (OOD) or Object-Oriented Analysis and Design (OOAD) are other terms for Low-Level Design. Top businesses allocate at least one stage of the interview process to system design, from interns to senior software engineers. Low Level Design is the most important factor for applicants with less than three years of experience, since these candidates are inexperienced and so are not expected to grasp High Level Design. Candidates with more than three years of experience often face system design interviews with a combination of HLD and LLD.

This course, Low Level System Design, focuses on the design's low-level features. The best way to improve at interviews is to practice a large number of comparable issues. Based on my study, a list of the most frequently asked questions in interviews is prepared in this course. This is important not only for interviews but also for general problem solving and application creation.

Who this course is for:

• Software Engineers
