Models for Efficient Data Replication in Cloud Computing Datacenters

Grazed from University of Luxembourg.  Author:  Dejene Boru, Dzmitry Kliazovich, Fabrizio Granelli, Pascal Bouvry, Albert Y. Zomaya.

Cloud computing is a computing model where users access ICT services and resources without regard to where the services are hosted. Communication resources often become a bottleneck in service provisioning for many cloud applications. Therefore, data replication which brings data (e.g., databases) closer to data consumers (e.g., cloud applications) is seen as a promising solution.

In this paper we present models for energy consumption and bandwidth demand of database access in cloud computing datacenter. In addition we propose an energy efficient replication strategy based on the proposed models which results in improved Quality of Service (QoS) with reduced communication delays...

Cloud Computing: Amazon data center on fire in Virginia

Grazed from Click2Houston.  Author: Editorial Staff.

A large fire lit up the roof of an Amazon data center that's still under construction in a Virginia suburb outside Washington, D.C.  No one was hurt in the blaze, according to the local fire department, which was able to put out the fire in under an hour.  Amazon said the facility was in the early stages of becoming an Amazon Web Services cloud computing center.

The company noted that the incident didn't impact company production or shipping.  The nondescript building will one day be one of Amazon's massive data centers -- the kind that keep websites running and store computer information for companies...

Google Dumps MapReduce in Favor of New Hyper-Scale Analytics System – Google has abandoned MapReduce, the system for running data analytics jobs spread across many servers the company developed and later open sourced, in favor of a new cloud analytics system it has built called Cloud Dataflow...

Cloud Computing: Disrupting the Data Center to Create the Digital Services Economy

Grazed from CIO. Author: Diane Bryant.

I had the pleasure of joining Tom Krazit on stage at the Gigaom Structure'14 conference to share Intel's vision of the data center in support of the growth of the digital services economy. We are in the midst of a bold industry transformation as IT evolves from supporting the business to being the business. This transformation and the move to cloud computing calls into question many of the fundamental principles of data center architecture.

Two significant changes are the move to software defined infrastructure (SDI) and the move to scale-out, distributed applications. The speed of application development and deployment of new services is rapid. The infrastructure must keep pace. It must move from statically configured to dynamic, from manually operated to fully automated, and from fixed function to open standard. As we have many times in our history, Intel is embracing this transformation and driving technology innovation to re-architect today's data centers for the future...

IBM Opens First Cloud Data Center With SoftLayer in Japan

Grazed from MarketWire.  Author: PR Announcement.

Today IBM announced the opening of its first cloud data center with SoftLayer in Japan, located in Tokyo. This announcement comes on the heels of recent SoftLayer cloud data center launches in Melbourne and Paris and represents the next step in IBM's $1.2 billion investment to expand its global cloud footprint.

The facility in Tokyo complements other SoftLayer resources located in cities within the Asia-Pacific region, including Singapore, Hong Kong, and Melbourne and broadens data redundancy options and geographic diversity within IBM's growing number of cloud data centers worldwide...

How Cloud Partners Can Identify (and Plug) Datacenter Security Holes

Grazed from RPCMag.  Author: Gladys Rama.

As solution delivery increasingly involves cloud-hosted services, solution providers regularly find themselves in the business of taking on new vendors who provide key services from datacenters over which the solution provider has no control. The vendors might be giants such as Amazon Web Services Inc. (AWS), Google Inc., Rackspace Inc. or Microsoft, with their own massive datacenters.

They might be smaller vendors providing their services from their own purpose-built datacenter. They might be a co-location arrangement with a services provider of any size. Or they may simply be reselling the service of another vendor, abstracting the whole question...

Cloud Computing: Take a Look Inside SingleHop's New State-of-the-Art $30 Million Data Center

Grazed from ChicagoInno.  Author: Editorial Staff.

With private cloud hosting companies, enterprises receive the same agility and control that they would with a public cloud provider (like DigitalOcean or AWS), but with fixed economics and superior hands-on service. Because of this, 'Hosted Private Cloud Solutions' has been SingleHop's fastest-growing and most popular product category in 2014.

To meet this demand, SingleHop - a Chicago-based provider of cloud computing and IT infrastructure - launched a brand new, state-of-the art $30 million data center today that features key capabilities designed specifically for hosting private clouds...

Cloud Computing: Why the data center needs an operating system

Grazed from OReilly. Author: Benjamin Hindman.

Developers today are building a new class of applications. These applications no longer fit on a single server, but instead run across a fleet of servers in a data center. Examples include analytics frameworks like Apache Hadoop and Apache Spark, message brokers like Apache Kafka, key-value stores like Apache Cassandra, as well as customer-facing applications such as those run by Twitter and Netflix.

These new applications are more than applications, they are distributed systems. Just as it became commonplace for developers to build multithreaded applications for single machines, it’s now becoming commonplace for developers to build distributed systems for data centers...

Global Cloud Computing Boosts the Mega Data Center

Grazed from Midsize Insider. Author: Marissa Tejada.

Global cloud computing is changing the future of the mega data center. Firms that aim to benefit from cloud computing will be a part of this future, according to new research.

Growth and Interconnection

A new report from Research and Markets featured in BusinessWire reveals that mega data centers will grow heavier in data loads thanks to the deluge of data that will continue to be transferred to them. According to the report, the growing global cloud computing market will provide the integration of both software and IT infrastructure. The data center landscape will be changed because firms can expand network capacity at a faster pace by moving their collaboration and computing applications via cloud computing...

Cloud Computing: Intel's Super Elastic Datacenter Bubble Plastic

Grazed from EnterpriseTech. Author: Timothy Prickett Morgan.

IT spending is growing at a few measly points a year, at best, and guess what? Diane Bryant, general manager of Intel’s Data Center Group, is not even breaking a sweat. And the reason why is simple: revenues from the chippery that Intel sells in servers, storage, and switches has been growing much faster than the market at large and is projected to do so out until 2018, which is the edge of Intel’s planning horizon.

At the company’s annual Investor Meeting late last week, the top brass of the chip giant gave Wall Street and the rest of us who care about Intel’s fortunes because so much of the datacenter is underpinned or driven by Intel some insight into how they think the future will play out...
