Object Storage with Gluster
This document discusses using Gluster object storage with OpenStack Swift. Gluster-Swift mounts the Swift storage using FUSE and allows Swift to interface with Gluster backends. This avoids reimplementing the Swift object API. Gluster-Swift overrides Swift's distribution and replication to use the Gluster backend. The Swift API is implemented using FUSE operations on the Gluster volume. Future work includes upgrading Gluster-Swift, packaging, optimizations, and potentially developing a native Gluster object interface.
GlusterFS As an Object Storage
A presentation for Lightning Talk Nite on Nov. 2nd 2011 in NTTPC Communications.
The demo was that I wrote a demo client in Ruby on site in real time.
はじめてのGlusterFS
The document discusses different approaches for distributed metadata management in scale-out storage systems. It describes the limitations of centralized and decentralized metadata approaches, which can result in overhead and single points of failure. It then introduces the Elastic Hash Algorithm used by GlusterFS, which hashes file paths to assign data across multiple volumes and physical devices in a way that provides load balancing, flexibility and avoids metadata bottlenecks. Diagrams illustrate how the algorithm works and how it allows elastic scaling of capacity and performance as needs change.
Rubyspec y el largo camino hacia Ruby 1.9
Rubyspec aims to provide an executable specification for the Ruby programming language to precisely define the language and allow implementations to test compatibility. It describes the development of Ruby 1.9 as requiring changes to the language, class hierarchy, encoding support, and object coercion. Implementations like JRuby, Rubinius, IronRuby, and MacRuby have progressed based on tests in Rubyspec. Future development of Ruby 2.0 may again require changes captured in the evolving specification.
Redis as a message queue
Redis is being used as a message queue to asynchronously process image uploads on a website for gaming screenshots. When a user uploads images, the application server adds a message to the Redis queue containing metadata about the upload. A separate process polls the queue and processes each upload by resizing images, creating database entries, and more. This allows upload processing to happen in the background without blocking the user.

Editor's Notes
- Service-oriented architecture , a computer systems architectural style for creating and using business processes, packaged as services . http://en.wikipedia.org/wiki/Service-oriented_architecture IT 資源 >> 服務 ( 設計層次高於 function, component, procedure) Web Service : Web APIs that can be accessed over a network, 可實現 xOA 的技術集合 http://en.wikipedia.org/wiki/Web_service RPC : distributed function (method) call interface. Mapping directly language-specific functions. SOAP : message, rather than an operation. REST : interacting with stateful resources. Roy Fielding , one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification. Style : (guideline) network architecture principles, outline how resources are defined and addressed. (Simple interface, Domain-specific data, Non-additional info) distributed hypermedia systems : such as the World Wide Web. ROA : 2007 book, RESTful Web Services. Every resource is a service. (Four concepts, four properties)
- https: TCP/IP model > Application Layer > HTTP
- Four concepts Resource : could be a physical resource, or even a person. Can be described by a representation. Name : URI for use in hypermedia links. Representation : HTTP header Content-type, describe the resource (XML / HTML / JSON / link). Link to : response to other resources. Four properties Addressability : set as URIs and allows clients to manipulate their state. Uniform interface : verbs reacting criteria (GET / PUT / POST / DELETE). Statelessness : server only keeps resource state; client keeps application state. Connectedness : have a set of links (URIs). REST principle > protocol : client-server, stateless, cacheable, layered (intermediaries)
- WSDL: an XML -based language that provides a model for describing Web services .
