Internet advertising services need to serve targeted advertising and must do so under limited time. These are just two of multiple technical challenges they face. AWS ADVERTISEMENT Amazon Web Services provides services and infrastructure to build reliable, fault-tolerant, and highly available ad serving platforms in the cloud. In this document, we describe the two main parts of such a system: ad serving infrastructure and click-through Reference SERVING collection featuring a data analysis cluster.

Reliability and Security of Large Scale Data Storage in Cloud Computing C.W
This article is part of the Reliability Society 2010 Annual Technical Report Reliability and Security of Large Scale Data Storage in Cloud Computing C.W. Hsu ¹¹¹ C.W. Wang ²²² Shiuhpyng Shieh ³³³ Department of Computer Science Taiwan Information Security Center at National Chiao Tung University NCTU (TWISC@NCTU) Email: ¹[email protected] ³[email protected] ²[email protected] Abstract In this article, we will present new challenges to the large scale cloud computing, namely reliability and security. Recent progress in the research area will be briefly reviewed. It has been proved that it is impossible to satisfy consistency, availability, and partitioned-tolerance simultaneously. Tradeoff becomes crucial among these factors to choose a suitable data access model for a distributed storage system. In this article, new security issues will be addressed and potential solutions will be discussed. Introduction “Cloud Computing ”, a novel computing model for large-scale application, has attracted much attention from both academic and industry. Since 2006, Google Inc. Chief Executive Eric Schmidt introduced the term into industry, and related research had been carried out in recent years. Cloud computing provides scalable deployment and fine-grained management of services through efficient resource sharing mechanism (most of them are for hardware resources, such as VM). Convinced by the manner called “ pay-as-you-go ” [1][2], companies can lower the cost of equipment management including machine purchasing, human maintenance, data backup, etc. Many cloud services rapidly appear on the Internet, such as Amazon’s EC2, Microsoft’s Azure, Google’s Gmail, Facebook, and so on. However, the well-known definition of the term “Cloud Computing ” was first given by Prof.

Dynamo Amazon DynamoDB Nicolas Travers Inspiré de Advait Deo Vertigo N. Travers ESILV : Dynamo Amazon DynamoDB – What is it ? • Fully managed nosql database service on AWS • Data model in the form of tables • Data stored in the form of items (name – value attributes) • Automatic scaling ▫ Provisioned throughput ▫ Storage scaling ▫ Distributed architecture • Easy Administration • Monitoring of tables using CloudWatch • Integration with EMR (Elastic MapReduce) ▫ Analyze data and store in S3 Vertigo N. Travers ESILV : Dynamo Amazon DynamoDB – What is it ? key=value key=value key=value key=value Table Item (64KB max) Attributes • Primary key (mandatory for every table) ▫ Hash or Hash + Range • Data model in the form of tables • Data stored in the form of items (name – value attributes) • Secondary Indexes for improved performance ▫ Local secondary index ▫ Global secondary index • Scalar data type (number, string etc) or multi-valued data type (sets) Vertigo N. Travers ESILV : Dynamo DynamoDB Architecture • True distributed architecture • Data is spread across hundreds of servers called storage nodes • Hundreds of servers form a cluster in the form of a “ring” • Client application can connect using one of the two approaches ▫ Routing using a load balancer ▫ Client-library that reflects Dynamo’s partitioning scheme and can determine the storage host to connect • Advantage of load balancer – no need for dynamo specific code in client application • Advantage of client-library – saves 1 network hop to load balancer • Synchronous replication is not achievable for high availability and scalability requirement at amazon • DynamoDB is designed to be “always writable” storage solution • Allows multiple versions of data on multiple storage nodes • Conflict resolution happens while reads and NOT during writes ▫ Syntactic conflict resolution ▫ Symantec conflict resolution Vertigo N.

Social media uses web-based technologies to turn communication into interactive dialogues. Andreas Kaplan and Michael Haenlein define social media as "a group of Internet-based applications that build on the ideological and technological foundations of Web 2.0, which allows the creation and exchange of user-generated content."[1] Businesses also refer to social media as consumer-generated media (CGM). Social media utilization is believed to be a driving force in defining the current time period as the Attention Age. A common thread running through all definitions of social media is a blending of technology and social interaction for the co-creation of value. Distinction from industrial media People gain information, education, news, etc., by electronic media and print media. Social media are distinct from industrial or traditional media, such as newspapers, television, and film. They are relatively inexpensive and accessible to enable anyone (even private individuals) to publish or access information, compared to industrial media, which generally require significant resources to publish information.
