2. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 1What is System Design? Systems design is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements. Following are the topics or pre-requisites: Grasp core computer science concepts like data structures, algorithms, and operating systems. Understand different database types (relational vs. NoSQL) and their functionalities. Know in detail about the System Design. Understand why System Design is important in software development. www.scholarhat.com

3. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 2 Key Components of a System Here's how each fits into the overall picture: Clients: Clients are the end-users or applications that interact with the system. Server: Servers are systems that host resources, services, or applications to clients. Databases: Databases are used to store and manage structured data. Caching: Stores frequently accessed data in memory. Load Balancing: Distributes incoming client requests across multiple servers to ensure optimal resource utilization and prevent overload on any single server. Proxies: Act as intermediaries between clients and servers, forwarding requests and responses. Scaling: Increases the capacity of the system to handle growing loads or user bases. www.scholarhat.com

4. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 3 System Design Basics: Reliability and Availability Reliability and availability ensures that systems are dependable and accessible to users. Here's a roadmap for beginners to understand and achieve reliability and availability: 1. Reliability 2. Availability 3. MTBF (Mean Time Between Failures) 4. MTTR (Mean Time To Repair/Recovery) 5. High Availability Architecture 6. SLA (Service-Level Argument) www.scholarhat.com

5. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 4Networking Networking facilitates communication between different components. Here's how networking fits into system design roadmap: 1. OSI Model (Open Systems Interconnection) 2. TCP/IP Protocol (Transmission Control Protocol/Internet Protocol) 3. IP Address Routing 4. DNS (Domain Name System) 5. CDN (Content Delivery Network) www.scholarhat.com

6. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 5Load Balancing A technique used to distribute workloads across multiple computing resources, such as computers, network links, or disks. Understand what is Load Balancer. Know about types of Load Balancing Algorithms: Round Robin, Least connections, Least Response Time and Weighted. Understand the difference between active-passive and active-active load balancing configurations. Differentiate between layer 4 (transport layer) and layer 7 (application layer) load balancing. www.scholarhat.com

7. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 6Consistency Here's a simplified roadmap for beginners to understand consistency in system design: Understand Weak, Eventual and Strong Consistency. Know about the CAP Theorem: The CAP theorem states that in a distributed system, it is impossible to simultaneously achieve consistency (C), availability (A), and partition tolerance (P). www.scholarhat.com

8. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 7Microservices and Proxies Here's a roadmap to understand microservices communication and proxies in system design: Understand different communication patterns used in microservices architecture, such as synchronous (HTTP, RPC) and asynchronous (message queues, event-driven). Explore service-to-service communication. Implement resilience patterns to handle failures and ensure fault tolerance in microservices communication. Understand the role of proxies for routing and load balancing. Learn about Forward and Reverse Proxies. www.scholarhat.com

9. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS A roadmap to understand storage in system design: 8Storage Understand thedifference between block, file, and object storage. Know about types of storage: Volatile and Non-Volatile. Understand RAID configurations for data redundancy and performance improvement: RAID 0 offers striping for performance. RAID 1 provides mirroring for data redundancy. RAID 5 and RAID 6 use parity for redundancy and storage efficiency. RAID 10 combines mirroring and striping for both redundancy and performance. Understand the architecture of HDFS, including Namenode, Datanode, and Secondary Namenode. www.scholarhat.com

10. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS 9 Message Queues and File Systems Understand asynchronous components of a system. Explore common use cases for message queues. Learn about popular message queue systems like Kafka and RabbitMQ. Understand the role of distributed file systems like GFS (Google File System) in storing large volumes of data across multiple nodes in a distributed environment. Learn about GFS architecture. Explore the design principles behind GFS, such as chunking, replication, and atomic operations. the role of message between queues in communication different www.scholarhat.com

11. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS A technique used to temporarily store copies of data in a 10Caching cache which is a high-speed data storage layer. Familiarize yourself with types of Caching: In-memory cache, Distributed cache, Database cache, Web caching Differentiate between Key-Value Database and Caching. Understand the challenges of cache invalidation and consistency maintenance: www.scholarhat.com

12. Swipe SYSTEM DESIGN ROADMAP FOR BEGINNERS Understand the importance of choosing appropriate 11API Contracts data formats for API contracts - JSON, XML or Protocol Buffers. Implement authentication mechanisms to secure API endpoints and control access to resources - Token- based, API Keys or OAuth. Implement rate limiting to prevent abuse and ensure fair usage of API resources - Throttling, Quotas and Dynamic Rate Limiting. www.scholarhat.com
