For distributed systems to work, a task must be broken down into smaller subtasks and distributed among multiple nodes or computers on a network. These nodes or computers then communicate and cooperate to finish the task.
The following four steps provide a brief overview of how distributed systems work:
decentralized components
A distributed system comprises numerous parts or nodes spread over various real or virtual locations. These parts can communicate with each other through a network to achieve a single goal.
Communication
Components of a distributed system can communicate with each other using a variety of protocols and tools, including TCP/IP, HTTP, or message queues. These protocols allow nodes to communicate by sending and receiving messages or data.
Coordination
For the parts of a distributed system to work well together, they must coordinate their actions. Various mechanisms, such as distributed algorithms, consensus protocols, or distributed transactions, can be used to achieve this coordination.
Fault tolerance
A distributed system should be built with fault tolerance in mind. This implies that it should be able to handle failure of specific parts or nodes without affecting the performance or availability of the entire system. Distributed systems employ redundancy, replication, or partitioning strategies to achieve fault tolerance.
An online search engine is an example of a distributed system, as it comprises numerous nodes that carry out various functions, including website crawling, content indexing, and handling user requests. These nodes cooperate to provide users with fast and effective search results.
The blockchain & mdash; a decentralized ledger that securely and transparently records transactions; it is also an example of a distributed system. It is distributed because the ledger is stored on multiple nodes in the network, and each node has a copy of the entire ledger, allowing for greater transparency, security, and resilience to failures or attacks.
