Study Notes
Distributed Systems and Cloud vs. Supercomputing
- Cloud computing offers a variety of services (IaaS, PaaS, SaaS) running on virtual machines, using commodity hardware and geographically distributed data centers.
- Supercomputing, on the other hand, involves dedicated services running on specialized machines built to run specific applications on dedicated topologies, typically deployed in a single location.
- Cloud computing networks are relatively less reliable compared to the more reliable servers, software, and network of supercomputing setups.
- Discrete-event Dynamic Systems (DEDS) model the transition of states in complex Distributed Systems, relying on asynchronous discrete events, with examples including Petri Nets, Stochastic Petri Nets, and Markov Chain.
- Petri Nets are a simple and graphical way to represent Distributed Systems, offering advantages like easy design and graphical illustration, but they can grow very fast and have no guidelines for correct representation.
- Synchronization with a time server involves using a time server with very accurate time, and Cristian’s algorithm is used in the Network Time Protocol (NTP) to estimate transmission delay and synchronize time.
- Different approaches to clocks include physical clocks, logical clocks such as Lamport and vector clocks, each with its own pros and cons in terms of implementation, synchronization, and causality.
- Mutual Exclusion Problem in distributed systems involves ensuring safety, liveness, and ordering, and can be solved using application-level protocols and alternative approaches like centralized, distributed, and token-ring approaches.
- Review of cloud computing highlights its design for different types of services, generic hardware, and relatively low processing applications, while high-performance computing is designed for specific, high-processing capacity services, using specialized hardware and typically deployed in a single location.
