Google Cloud Issue Summary Multiple Products - 2020-08-19 All Dates/Times Relative to US/Pacific
Google Cloud Issue Summary Multiple Products - 2020-08-19 All dates/times relative to US/Pacific Starting on August 19, 2020, from 20:55 to 03:30, multiple G Suite and Google Cloud Platform products experienced errors, unavailability, and delivery delays. Most of these issues involved creating, uploading, copying, or delivering content. The total incident duration was 6 hours and 35 minutes, though the impact period differed between products, and impact was mitigated earlier for most users and services. We understand that this issue has impacted our valued customers and users, and we apologize to those who were affected. DETAILED DESCRIPTION OF IMPACT Starting on August 19, 2020, from 20:55 to 03:30, Google Cloud services exhibited the following issues: ● Gmail: The Gmail service was unavailable for some users, and email delivery was delayed. About 0.73% of Gmail users (both consumer and G Suite) active within the preceding seven days experienced 3 or more availability errors during the outage period. G Suite customers accounted for 27% of affected Gmail users. Additionally, some users experienced errors when adding attachments to messages. Impact on Gmail was mitigated by 03:30, and all messages delayed by this incident have been delivered. ● Drive: Some Google Drive users experienced errors and elevated latency. Approximately 1.5% of Drive users (both consumer and G Suite) active within the preceding 24 hours experienced 3 or more errors during the outage period. ● Docs and Editors: Some Google Docs users experienced issues with image creation actions (for example, uploading an image, copying a document with an image, or using a template with images). -

Web 2.0 Services
Web 2.0 services: these objects are closer than they appear EDUCAUSE Evolving Technologies Committee Malcolm Brown, Dartmouth College [email protected] September, 2006 What is it? Web 2.0 services are a very broad range of network-based, cross platform services. This is an area that is expanding rapidly, so rapidly in fact that columnists and bloggers are drawing parallels to the dot com boom. The diversity of these services and their relentless pace of evolution make it challenging to define this evolving technology succinctly. A useful O’Reilly article1 suggests that the “Web 2.0” is less of a standard and more of a “gravitational core,” drawing applications into a common technology and functionality space rather than riveting them in place by means of a firm engineering standard. Much has already been written about these services, so there is no need to recapitulate that here. The O’Reilly article provides an excellent overview. But what may not be apparent unless you are following this technology closely is that it is evolving, expanding, and diversifying at an astonishing rate, and it is coming—has come—to a campus near you. While it might be difficult to define web services in a sentence or two, we can try to get a handle on it by identifying the technology’s key characteristics. They are diverse. Emily Chang’s eHub site2 provides an excellent overview of Web services. At last count, she documents 1,066 web-based resources using 64 categories, including business, Internet phone and TV, audio and music, collaboration and management, mashups, social web, travel, e-learning, e-mailing (and many more). -

Cloud Computing Influence on Operating System
Sci.Int.(Lahore),27(1),225-230,2015 ISSN 1013-5316; CODEN: SINTE 8 225 CLOUD COMPUTING INFLUENCE ON OPERATING SYSTEM Zain Tahir, Muhammad Aslam, Mishall Fatima* Department of Computer Science, UET, Pakistan * Department of Computer Engineering, NUST Pakistan Corresponding author: [email protected] ABSTRACT: In last decade internet usage has increased tremendously. Internet subsequently the Web has changed the way how people think about using computers in their daily life. This enormous shift towards the Web is made possible by many internet enable electronic gadgets which provide access virtually from anywhere to the Web. In this paper, we have studied different Web operating systems in terms of designs, architecture, and functionalities. A positive association has been found how cloud computing affects the traditional desktop operating system and shifting it to the cloud, Web, and mobile. To consolidate our arguments, we have presented case studies of different cloud operating systems like Windows Azure, Chrome OS, Eye OS, and you OS. However, cloud based operating system would be main focus in future with involvement of intelligent agents. Keywords: Cloud computing, Mobile computing, Traditional operating system, Web OS 1.

An Experimental Study of Load Balancing of Opennebula Open-Source Cloud Computing Platform
An Experimental Study of Load Balancing of OpenNebula Open-Source Cloud Computing Platform A B M Moniruzzaman, StudentMember, IEEE Kawser Wazed Nafi Syed Akther Hossain, Member, IEEE & ACM Abstract— Cloud Computing is becoming a viable computing organization existing computing infrastructure into a private or solution for services oriented computing. Several open-source hybrid cloud [3]. Eucalyptus, CloudStack, OpenStack and cloud solutions are available to these supports. Open-source OpenNebula are the most popular open-source cloud solutions software stacks offer a huge amount of customizability without used as to build such community cloud platforms. Eucalyptus huge licensing fees. As a result, open source software are widely is open source cloud software for building AWS-compatible used for designing cloud, and private clouds are being built private and hybrid clouds [4]. Apache CloudStack is open increasingly in the open source way. Numerous contributions source software designed to deploy and manage large networks have been made by the open-source community related to of virtual machines Infrastructure as a Service (IaaS) cloud private-IaaS-cloud. OpenNebula - a cloud platform is one of the computing platform [5]. OpenStack is a cloud operating system popular private cloud management software. However, little has that controls large pools of compute, storage, and networking been done to systematically investigate the performance evaluation of this open-source cloud solution in the existing resources throughout a datacenter, all managed through a literature. The performance evaluation aids new and existing dashboard that gives administrators control while empowering research, industry and international projects when selecting their users to provision resources through a web interface [6]. -
