Amazon Dynamodb
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. -

Eucalyptus - Installation Manual
Eucalyptus - Installation Manual Hannes Gamper and Tomi Pievil¨ainen December 3, 2009, Espoo Contents 1 Introduction 1 2 Requirements 1 3 Installation procedure 2 3.1 Install Ubuntu 9.10 Server edition and Ubuntu Enterprise Cloud . 2 3.2 Step 1 - Prerequisites . 2 3.3 Step 2 - System Installation and Configuration . 2 3.4 Step 3 - Registering UEC Components . 3 3.5 Step 4 - Initial Login . 3 1 Introduction Cloud computing systems provide users with access to large amounts of computational resources and data [4]. Virtualisation is used to hide information like physical location and architectural details of the resources from the user. Eucalyptus is an open-source software framework for cloud computing implementing Infrastructure as a Service (IaaS). It is tailored for the use in the research community. Users can run and control virtual machine instances on a variety of physical resources found within academic settings. 2 Requirements Eucalyptus can be installed via the Ubuntu Enterprise Cloud, introduced in Ubuntu 9.04 [3]. The following installation instructions are based on Ubuntu 9.10 Server edition. In terms of hardware requirements recommended minimum specification is a a dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. 1 3 Installation procedure • Ubuntu 9.10, server edition • dual-core 2.2 GHz processor with virtualization extension (Intel-VT or AMD-V), 4GB RAM and 100 GB hard drive. • port 22 needs to be open for admins (for maintenance) • port 8443 needs to be open for users for controlling and sending requests to the cloud via a web interface 3 Installation procedure The installation instructions in this manual closely follow those given on the \Ubuntu Enterprise Cloud" homepage [2], with some remarks regarding installation from scratch via the Ubuntu 9.10 server edition. -
