In simple Cloud computing is using the internet to access someone else's software running on someone else's hardware in someone else's data center.

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

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.

WebDAV

CardDAV

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 ServerAtmail,GMail and Google Contacts allow access to user's address book via CardDAVGroup-OfficeZimbra 6 allows access to its address book via CardDAV

CalDAV

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.

Connecting external storages

- 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)

High availability

Elimination of single points of failure.

Reliable crossover.

Detection of failures as they occur.

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)

Redundancy

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.

GlusterFS

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 its 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.

Hadoop

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.
