high availability And File hosting service (OwnCloud)
This document provides information about file hosting services and cloud computing. It discusses that cloud computing involves using software and hardware resources owned and maintained by third parties via the internet. It also defines Software as a Service (SaaS) and notes criticism of cloud computing from Richard Stallman. The document then outlines features of file hosting services including mobile and desktop clients, encryption of user files, and additional services like calendars, address books and media streaming. It also discusses high availability and redundancy measures for file storage, web servers and databases.

Editor's Notes
- #4 BaaS desktop as a service (DaaS) backend as a service (BaaS) MBAAS Authentication as a service XAAS
- #6 On-demand Gmail. Google doc. Accounting
- #16 PHP JavaScript sabre/dav open-source WebDAV server SQLite MariaDB MySQL Oracle Database PostgreSQL Sabre Saiber
- #17 Web Distributed Authoring and Versioning (WebDAV) is an extension of the HTTP that allows clients to perform remote Web content authoring operations. The WebDAV protocol provides a framework for users to create, change and move documents on a server, typically a web server or web share. Apache HTTP Server provides WebDAV modules based on both davfs and Apache Subversion (svn). Microsoft's IIS also has a WebDAV module.
- #19 vCard Extensions to WebDAV (CardDAV) is an address book client/server protocol designed to allow users to access and share contact data on a server. Apple Contacts Server Atmail, GMail and Google Contacts allow access to user's address book via CardDAV Group-Office Zimbra 6 allows access to its address book via CardDAV
- #20 Calendaring Extensions to WebDAV, or CalDAV, is an Internet standard allowing a client to access scheduling information on a remote server. It extends WebDAV (HTTP-based protocol for data manipulation) specification and uses iCalendar format for the data.
- #21 Send SMS to cloud
- #22 The News app is an RSS/Atom feed reader which can be synced with many mobile devices.
- #25 - If you are a Mozilla Firefox user, all history, form data, bookmarks etc. can be stored in your OwnCloud server. Connecting external storages (if you have accounts on Dropbox, GoogleDrive, or Amazon S3, you can mount those storages into your OwnCloud installation)
- #26 A single point of failure (SPOF) is a part of a system that, if it fails, will stop the entire system from working. SPOF Reliable crossover in this context means: The ability to switch from a node X (which is broken somehow) to a Node Y without losing data. Reliable HA-database example: Setting up data replication where (per example) your insert statement only returns as "executed OK" when the transaction is copied to the secundary server. (yes: data replication is more complex then this, this is a simplified example in the context of the question)
- #27 In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe.
- #28 Redundancy
- #30 location-independent addressing redundancy which improve reliability reduce the complexity of the other parts of the cluster write once read anywhere replication fault tolerance and redundancy error correction scalable horizantally many opensource option avalable narrowed down to tree to evaluate
- #31 spread data across multiple storage nodes, usually for redundancy or performance
- #33 specific folder in fixed order file path file name date
- #36 GNU cluseter network-attached storage GLUSTER
- #37 Server – the server is used to perform all the replication between disks and machine nodes to provide a consistent set of data across all replicas. The server also handles client connections with it’s built in NFS service. Client – this is the software required by all machines which will access the GlusterFS storage volume. Clients can mount storage from one or more servers and employ caching to help with performance.
- #38 Hadoop Distributed File System (HDFS) Apache License 2.0.
- #39 An HDFS cluster primarily consists of a NameNode and the DataNode. The NameNode manages the file system metadata and DataNodes are used to store the actual data.
- #40 Linux and cluster GNU General Public License (version 2 only) it has consistently been used by at least half of the top ten, and more than 60 of the top 100 fastest supercomputers in the world
- #43 the next generation of Parallel Virtual File System Performance Reliability Optimized MPI-IO support Hardware Independence Painless Deployment Research Platform
- #44 open source digital object repository server Fedora-commons is an open source repository (not a Linux distribution) accounts for all changes, so it provides built-in version control provides disaster recover open standards to mesh with future file formats provides open sharing services such as OAI-PMH
- #45 open source digital object repository server Fedora-commons is an open source repository (not a Linux distribution) accounts for all changes, so it provides built-in version control provides disaster recover open standards to mesh with future file formats provides open sharing services such as OAI-PMH
- #46 Its generic synchronous multi-master replication plugin for transactional applications.
