Storm is a distributed real-time computation system for processing streaming data. It provides abstractions called topologies, spouts, and bolts. A topology defines the flow of data between spouts, which act as sources, and bolts, which perform processing. Storm distributes the computation across a cluster of machines coordinated by a master node called Nimbus and worker nodes called supervisors.

요즘 Hadoop 보다 더 뜨고 있는 Spark.
그 Spark의 핵심을 이해하기 위해서는 핵심 자료구조인 Resilient Distributed Datasets (RDD)를 이해하는 것이 필요합니다.

This document provides an overview of resource aware scheduling in Apache Storm. It discusses the challenges of scheduling Storm topologies at Yahoo scale, including increasing heterogeneous clusters, low cluster utilization, and unbalanced resource usage. It then introduces the Resource Aware Scheduler (RAS) built for Storm, which allows fine-grained resource control and isolation for topologies through APIs and cgroups. Key features of RAS include pluggable scheduling strategies, per user resource guarantees, and topology priorities. Experimental results from Yahoo Storm clusters show significant improvements to throughput and resource utilization with RAS. The talk concludes with future work on improved scheduling strategies and real-time resource monitoring.
Storm: distributed and fault-tolerant realtime computationnathanmarz
Storm is a distributed real-time computation system that provides guaranteed message processing, horizontal scalability, and fault tolerance. It allows users to define data processing topologies and submit them to a Storm cluster for distributed execution. Spouts emit streams of tuples that are processed by bolts. Storm tracks processing to ensure reliability and replays failed tasks. It provides tools for deployment, monitoring, and optimization of real-time data processing.

This document summarizes sessions from the Samsung Open Source Conference from October 26-28. It discusses the Linux kernel boot process, IoT frameworks like IoT.js and JerryScript.js, and the Apache Horn project for big data and deep learning using a neuron-centric approach. The Linux kernel boot process initiates start_kernel() and mm_init() from over 15 million lines of code. IoT.js and JerryScript.js provide lighter alternatives to Node.js for IoT applications. Apache Horn is an open source project for deep learning that focuses on neurons.
This document provides an introduction and overview of an Advanced Operating Systems course. The course will take approximately 5 weeks to complete and have 11 lessons. It will cover topics like abstractions, OS structure, virtualization, parallelism, distributed systems, and security. Each lesson will be released weekly and students are expected to spend around 6 hours per week to complete the material.
The document discusses a presentation on real-time analytics using Apache Storm. It covers basic Storm theory and setup, using Twitter streams with Storm, practices building streaming joins and exclamation topologies, and concludes with discussing student project teams analyzing sentiment, geography, ebola topics, and their use of tools like OpenCV.
[Taewoo Kim] Real-Time Analytics with Apache StormTaewoo Kim
This document summarizes a study on real-time analytics using Apache Storm. It outlines four parts to the study: 1) learning the theory, setup, and basics of Storm, 2) using Storm with Twitter streams, 3) going beyond basic Storm concepts with an example join, and 4) participating in a Storm project and hackathon. It then describes two practices - parsing tweet URLs and tracking top hashtags - to demonstrate Storm's use for real-time analytics on Twitter data streams.
This document outlines a plan to study real-time analytics using Apache Storm. It describes setting up Storm and completing basic tutorials on processing streaming data. The plan is to first learn Storm's theory and setup, then complete examples using Twitter streams and more advanced Storm techniques before participating in a Storm hackathon project.
Storm is an open source distributed real-time computation system from Apache that allows processing streams of data in real-time. It is composed of spouts which act as sources of data streams and bolts which perform processing on the data. Topologies define the layout of spouts and bolts and how data flows between them. Common groupings in Storm include shuffle, fields, all, and global groupings which determine how data is distributed between processing tasks.
