Data replication
Data replication is a critical technique used in distributed systems to enhance data availability, fault tolerance, and reliability. By maintaining multiple copies of the same data across different nodes or servers, replication ensures that data remains accessible even in the event of a failure. This approach is widely used in cloud computing, distributed databases, and…

Distributed System Architecture
Distributed system architecture refers to a computing model in which components of a system are spread across multiple machines, yet function as a cohesive unit. These systems are designed to achieve scalability, fault tolerance, and high availability by leveraging the capabilities of multiple nodes or servers. Distributed systems are foundational to cloud computing, large-scale web…

Micro service Architecture
Microservice architecture (MSA) is a design style that structures an application as a collection of small, autonomous, and independently deployable services. Each service is designed to fulfill a specific business function and communicates with other services through lightweight protocols like HTTP, REST, or messaging queues. This architecture is a modern alternative to monolithic systems, enabling…

Availability : CAP Theorm
Availability in CAP: Ensuring Continuous Responsiveness in Distributed Systems The CAP theorem, formulated by Eric Brewer, is foundational to understanding the design trade-offs in distributed systems. It asserts that a distributed system can simultaneously provide only two of three properties: Consistency (C), Availability (A), and Partition Tolerance (P). In this context, availability ensures that every…
