What is High-Level Design?

High-level design or HLD refers to the overall system, a design that consists description of the system architecture and design and is a generic system design that includes:

  • System architecture
  • Database design
  • Brief description of systems, services, platforms, and relationships among modules.

High-level design or HLD is also known as macro level designing.

System Design Interview Bootcamp – A Complete Guide

We all know that System Design is the core concept behind the design of any distributed system. Therefore every person in the tech industry needs to have at least a basic understanding of what goes behind designing a System. With this intent, we have brought to you the ultimate System Design Interview Bootcamp, a one-stop solution for learning System Design.

The most important stage in any development process, be it Software or any other tech, is Design. Without the designing phase, you cannot jump to the implementation of the testing part. The same is the case with the System as well.

2. Procedure to Design Systems

System design is the process of designing the architecture and components of a software system to meet specific business requirements. The process involves defining the system’s architecture, components, modules, and interfaces, and identifying the technologies and tools that will be used to implement the system. Here are some steps to get started with system design:...

5. Message Queues

Message queues facilitate communication between distributed systems by allowing asynchronous communication. This decouples the components, enabling them to operate independently and improving system reliability. It is a form of communication and data transfer mechanism used in computer science and system design. It functions as a temporary storage and routing system for messages exchanged between different components, applications, or systems within a larger software architecture....

Distributed System is a collection of autonomous computer systems that are physically separated but are connected by a centralized computer network that is equipped with distributed system software. The autonomous computers will communicate among each system by sharing resources and files and performing the tasks assigned to them....

11. Distributed System Failures

Method failure:  In this type of failure, the distributed system is generally halted and unable to perform the execution. Sometimes it leads to ending up the execution resulting in an associate incorrect outcome. Method failure causes the system state to deviate from specifications, and also method might fail to progress. System failure: In system failure, the processor associated with the distributed system fails to perform the execution. This is caused by computer code errors and hardware issues. Hardware issues may involve CPU/memory/bus failure. This is assumed that whenever the system stops its execution due to some fault then the interior state is lost. Secondary storage device failure: A storage device failure is claimed to have occurred once the keep information can’t be accessed. This failure is sometimes caused by parity error, head crash, or dirt particles settled on the medium. Communication medium failure: A communication medium failure happens once a web site cannot communicate with another operational site within the network. it’s typically caused by the failure of the shift nodes and/or the links of the human activity system....

13. UML Diagrams for System Design

Unified Modeling Language (UML) is a general purpose modelling language. The main aim of UML is to define a standard way to visualize the way a system has been designed. It is quite similar to blueprints used in other fields of engineering. UML is not a programming language, it is rather a visual language. We use UML diagrams to portray the behavior and structure of a system...

17. Machine Learning and System Design

System design in machine learning is vital for scalability, performance, and efficiency. It ensures effective data management, model deployment, monitoring, and resource optimization, while also addressing security, privacy, and regulatory compliance. A well-designed system enables seamless integration, adaptability, cost control, and collaborative development, ultimately making machine learning solutions robust, reliable, and capable of real-world deployment....

18. Containerization and System Design

Containerization is a lightweight form of virtualization that allows applications and their dependencies to be packaged and run consistently across different computing environments. Containers encapsulate an application, its runtime, libraries, and other dependencies, ensuring that it runs consistently regardless of the environment in which it is deployed. Docker, a widely used containerization platform, popularized this approach, but other containerization technologies exist, such as containerd and Podman....
