Study Notes
Cloud Computing
- High-Throughput Computing (HTC) prioritizes the speed of completing tasks, particularly in high-flux environments like internet searches and web services
- Centralized computing brings all resources (processors, memory, and storage) to a single physical system. Data centers and some supercomputers use this approach for parallel processing
- Parallel computing uses multiple processors, either tightly coupled (shared memory) or loosely coupled (distributed memory) to perform tasks simultaneously through message passing or shared memory. Programs run in parallel
- Distributed computing uses multiple autonomous computers connected via a network. Information is exchanged via message passing distributed programs.
- Cloud computing is a utility computation model that uses distributed and parallel computing over large data centers, either centralized or distributed. It provides access to a pool of resources for various workloads and is often flexible and scalable.
Computing Paradigm Distinctions
- Centralized computing uses a single physical system
- Parallel computing uses multiple processors. It can be tightly coupled (shared memory) or loosely coupled (distributed memory)
- Distributed computing utilizes multiple computers connected via a network
