This article is my understanding and thoughts on the operator layer of distributed computing. Because recently my development tasks are also related to this issue, the company's self-developed streaming computing framework requires an operator layer. I mainly analyze the implementation of Operators on stream systems, compare the existing computing frameworks with
The IT industry is always not introducing new concepts, so we will not be confused. NC, grid computing, IPv6, Web2.0, SOA, SAAS ...... Some of them have changed our lives.
Nearly 10 years after the concept of "Grid" was proposed, another new concept "cloud computing" similar to its release version was re-proposed.
An excerpt from the explanatory description of cloud com
What is cloud computing? Cloud computing is an Internet-based super computing model. In a remote data center, thousands of computers and servers are connected to a single computer cloud. Therefore, cloud computing can even allow you to experience 10 trillion operations per second. With such powerful
Cloud computing is developing very quickly. And here are 5 things we can't avoid, the truth that can help business development:
The truth: Cloud computing is fashionable
Truth: No, the cloud is not a new thing. Just a ... Disruptive innovation.
Truth #3: Yes, cloud computing poses a security risk for privacy and reliability
Truth #4: Software Architect, ready
Cloud computingThere are at least 20 definitions of cloud computing so far, and a more common definition has been chosen:Cloud computing is a kind of distributed computing technology, the most basic concept is to automatically split the huge computational processing program into countless smaller sub-programs through the network, and then the large system compose
Introduction
In all recent attention to cloud computing, storage is more regarded as a basic platform. Today, many cloud computing products are limited to the collection of CPU cores, quantitative memory allocation, low-speed storage, or some Internet-Oriented IP technologies. Recently, there have been interesting advanced technologies related to cloud computing
[Report] cloud computing is the development of parallel computing, distributed computing, and grid computing, or the commercial implementation of these computing scientific concepts. Cloud computing is virtualization, utility
In the movie "Avatar", all creatures on Pandora are connected to an organic whole through a neural network that is more complex than the human brain, forming a close and harmonious ecosystem. Jack and Nari rely on this magical collective power to defeat intruders. Do you realize that the Internet on the earth is gradually evolving into a similar organic whole, and the emergence of cloud computing is intertwined with 3G and IOT, it indicates that the p
Since the birth of the computer, it has undergone a revolutionary transformation from a giant computer to a PC. Today, it has become the most effective assistant for people in daily work and home entertainment, but if someone tells you that you can order computing services as conveniently as using gas and electricity, will you believe it? Sun's CEO, Jonathan schouaz, once said that it was a commercial stunt to get the company's large amount of
Many enterprise IT professionals think of cloud computing as a low-level form of outsourcing. This reflects the fact that most cloud-based services are still not up to corporate standards and cannot be supervised and controlled by IT managers.
However, the business sector sees the concept of cloud computing as an attractive option. The business unit is puzzled by the speed with which the enterprise IT depa
As the GPU's programmability continues to increase, the GPU's application capabilities have far exceeded the graphics rendering task, and the use of GPU to complete general-purpose computing is becoming increasingly active, use GPU for computing outside of graphics rendering to becomePurpose computing on graphics processing units, GPU-based general-purpose

Cloud theory is a powerful tool for natural conversion between the qualitative value of a concept and the quantitative value of a number.
Based on the cloud theory, this paper proposes a cloud computing method for implementing conceptual computing (also called simplified computing. The cloud model and uncertainty reasoning are outlined. The logic description of
Chapter 1 virtualization and cloud computing 1. Definition of Virtualization
Virtualization is a broad term. Different industries have different understandings of virtualization, and different people have different understandings of virtualization. Therefore, there is no standard definition.
A virtualization is a process in which users and applications can easily represent computer resources, instead of expressing these resources in a proprietary mann
Currently, if we want to fully understand cloud computing, we should understand both the "service" and "Platform", that is, cloud computing covers the cloud computing platform and cloud computing service concepts.
As mentioned above, cloud computing services represent a new

Fog computing is an extension of cloud computing. It was first created by Cisco. The name of "fog" due to "cloud" comes from the phrase "fog is a cloud closer to the ground.
Like cloud computing, fog computing is very impressive. Clouds float in the sky, high above, out of reach, deliberately abstract; while fog is rea
Cloud computing This new term has been rampant recently, many friends have been talking around, it is necessary to write a science about cloud computing.
The general industry prefers to use some of the term to reflect their strategic vision and the opponent's partition. When Google introduced the concept of cloud computing a few months ago, Amazon said it was cl
