Distributed System

/dɪˈstrɪbjuːtɪd ˈsɪstəm/

noun — “a collection of independent computers that behave like a single system, until something breaks and reveals the seams.”

A Distributed System is a computing model in which multiple independent machines work together over a network to achieve a common goal. Instead of relying on a single machine to store data or execute logic, the workload is split across several nodes that communicate, coordinate, and cooperate as if they were parts of one larger system.

Microservices

/ˈmaɪkroʊˌsɜrvɪsɪz/

noun — “a way of building software by breaking it into small, independently deployable pieces that pretend they are simple but rarely are.”

Microservices is an architectural style in which a software system is composed of many small, loosely coupled services, each responsible for a specific business capability. Each service runs independently, communicates over a network, and can be developed, deployed, and scaled without requiring the entire system to be rebuilt or redeployed.

SOA

/ˈsɜrvɪs ˈɔriˌɛntɪd ˈɑrkəˌtɛkʧər/

noun — “an architectural approach where software behaves less like a monolith and more like a federation of cooperating services.”

Software Design

/ˈsɒftˌwɛr dɪˈzaɪn/

noun — “the art of deciding how software should think, behave, and survive contact with reality.”

Software Design is the process of planning, structuring, and organizing software systems before and during development. It defines how components interact, how data flows, how features behave, and how the entire system remains maintainable over time. Good software design is not merely about making code function—it is about creating systems that remain understandable, adaptable, efficient, and stable even as complexity grows.

Client–Server Model

/ˈklaɪ.ənt ˈsɜːr.vər ˈmɒd.əl/

noun — “the digital handshake that keeps your apps and servers from fighting over data.”

Client–Server Model is a network architecture where tasks and workloads are divided between service providers, called servers, and service requesters, called clients. In this model, clients initiate requests for resources or services, and servers respond by providing data, computation, or functionality. This separation allows multiple clients to access shared resources efficiently while centralizing control on the server side.

Distributed Systems

/dɪˈstrɪbjʊtɪd ˈsɪstəmz/

noun … “Independent computers acting as one system.”

Distributed Systems are computing systems composed of multiple independent computers that communicate over a network and coordinate their actions to appear as a single coherent system. Each component has its own memory and execution context, and failures or delays are expected rather than exceptional. The defining challenge of distributed systems is managing coordination, consistency, and reliability in the presence of partial failure and unpredictable communication.

SIMD

/sɪmˈdiː/

n. "Single Instruction Multiple Data parallel processing executing identical operation across vector lanes simultaneously."
