Distributed system

As explained in Rust Servers, Services, and Apps

A distributed system is a collection of independent computing components that coordinate over a network to provide combined functionality.

A distributed system has components that may run on different processors, communicate over a network, and execute workloads concurrently. A distributed web application is a non-monolithic program whose components cooperate over a network. section 1.1

A web application’s distributed-system stack has three parts:

• Distributed applications, whose components communicate using networking protocols. section 1.1
• A networking stack. section 1.1
• Hardware and operating-system infrastructure. section 1.1

HTTP is a common choice for communication between a web application and the outside world. Backend services, frontends, and infrastructure have distinct concerns, including availability, user experience, and low-level resource control. section 1.1 section 1.2

A social media application

A social media service can distribute features across servers, with components implemented using different design choices, languages, and locations. Facebook and Twitter are examples of large-scale distributed web applications. section 1.0 section 1.1

How Rust Servers, Services, and Apps covers it

How deep it goes

Defines system components and stack layers, then relates them to web applications without detailing implementation internals.

Examples

Uses social media, e-commerce, sharing-economy, and entertainment services, plus a social media stack diagram.

What you can do after

Build Rust web servers, services, and applications using the distributed-web context.

How it connects

Connects distributed systems with distributed applications, client-server applications, peer-to-peer applications, HTTP, and web applications.
