Efficiency: Distributed systems break complex data into smaller pieces.Low latency: You can have a node in multiple locations, so traffic will hit the closest node.Cost-effective: The initial cost is higher than traditional systems, but because of their capacity to scale, they quickly become more cost-effective.Fault tolerance: Distributed systems are more fault-tolerant than single machines.Modular growth: There’s almost no cap on how much you can scale.Scaling: Distributed systems allow you to scale horizontally to account for more traffic.These machines can also fail independently without affecting the entire system.ĭistributed systems can be difficult to deploy and maintain, but they provide many benefits, including: All of the computers in the collection share the same state and operate concurrently. A distributed system is a collection of computers that work together to form a single computer for the end user. Many top tech companies use complex distributed systems to handle billions of requests and perform updates without downtime. This guide details the fundamental concepts of system design and also links you to relevant resources to help you gain a deeper understanding and acquire real-world, hands-on experience.ĭistributed systems make it easier for us to scale our applications at exponential rates. So, no matter what your level is, system design matters to you.īecause of its increasing importance, we wanted to create a resource to help you navigate the world of system design. As you progress through your career and begin interviewing for higher-level positions, system design will become a larger part of your interview process. In the early stages of your career, learning system design will allow you to tackle software design problems with more confidence and apply design principles to your everyday work. This is where system design comes in.Īs a software developer, you’ll be increasingly expected to understand system design concepts and how to apply them. Billions of people worldwide access these systems concurrently, so they need to be designed to handle large amounts of traffic and data. All of the apps and services that we use daily, like Facebook, Instagram, and Twitter, are scalable systems.
These advancements have redefined the way we think about software development. Over the last two decades, there have been a lot of advancements in large-scale web applications.
