Hadoop structure

Hadoop Introduction

The Hadoop Distributed File System (HDFS) is a distributed file system designed to run on commodity hardware. It has many similarities with existing distributed file systems. However, the differences from other distributed file systems are significant. HDFS is highly fault-tolerant and is designed to be deployed on low-cost hardware. HDFS provides high throughput access to application data and is suitable for applications that have large...

Cloud Computing Tools

Various Cloud Simulation tools available in Cloud Computing

Cloud computing is a new and emerging technology where the computer hardware and software that we use on our desktop is shared over the internet and we could access such computing facilities typically by purchasing it as a service from another company. This sharing of computing is being made possible with the extensive use virtualization technologies and distributed computing. The Cloud computing providers offer their...

Hadoop and Word Count | Hadoop Distributed File System

Hadoop is an Apache open source framework written in Java that allows distributed processing of large datasets across clusters of computers using simple programming models. A Hadoop frame-worked application works in an environment that provides distributed storage and computation across clusters of computers. Hadoop is designed to scale up from a single server to thousands of machines, each offering local computation and storage. Hadoop Architecture...

Cloud and Fog computing

Fog computing vs Cloud computing

Cloud Computing, is defined as a group of computers and servers connected together over the Internet to form a network. Today, as many enterprises and large organizations are beginning to adopt the Internet of Things, the need for large amounts of data to be accessed more quickly, and locally, is ever-growing. This is where the concept of “Fog Computing” comes to play. Fog Computing, or “fogging”, is...

Cloud security issues


THREATS IN CLOUD COMPUTING Threats Cloud computing faces just as much security threats that are currently found in the existing computing platforms, networks, intranets, internets in enterprises. These threats, risk vulnerabilities come in various forms. The Cloud Security Alliance (Cloud Computing Alliance, 2010) did a research on the threats facing cloud computing and it identified the flowing major threats: Failures in Provider Security Attacks by...

Eucalyptus Cloud Computing Architecture

Eucalyptus is an open source software platform for implementing Infrastructure as a Service (IaaS) in a private or hybrid cloud computing environment. Eucalyptus cloud computing architecture is highly scalable because of its distributed nature. The Cloud level of the computing architecture is comprised of only two components and while used by many users, the transactions at each component are typically small. The Node level may have many...
