TOPIC

• CLOUD OPERATING SYSTEM - EYEOS

2
Lets first talk about a CLOUD OS

• A cloud OS simply refers to an operating system
  (or an interface filled with a complete suite of
  desktop applications) that resides on the Web and
  you can access to it anytime, anywhere as long as
  you have an Internet connection.

3
OPERATING SYSTEM

• Its the software that enables the interaction
  between user and system
• Cloud can be installed and used together with
  other operating systems, or can act as a
  standalone operating system. When used as a
  standalone operating system, hardware
  requirements are relatively low.

FEATURES EYEOS

• eyeOS is its small file size and ease of
  installation.
• EyeOS is a free and open source cloud OS software
  that you can install on your own Web server.
• From Cloud the user can quickly boot into the
  main OS, because Cloud continues booting the main
  OS in the background.
• Boot in few seconds.

18
facts!!

• Combining a browser with a basic operating system
  also allows the use of cloud computing, in which
  applications and data "live and run" on the
  Internet instead of on the hard drive.

VERSIONS OF EYEOS.

•  eyeOS version 0.6.0 on August 1, 2005 .
• eyeOS 1.0 on June 4, 2007.
• eyeOS 1.1 on July 2, 2007.
• eyeOS 1.2 after few maonths .
• eyeOS 1.5 Gala on January 15, 2008.
• eyeOS 1.6  on April 25, 2008.
• eyeOS 1.8 Lars  on January 7, 2009 .

20
Changes with versions.

• The first publicly available eyeOS version was
  released on August 1, 2005 as eyeOS 0.6.0
  in Barcelona (Spain). At the time, it greatly
  participated in creating the definition of a web
  operating system and acted as a concept. Quickly,
  a worldwide community of developers took part in
  the project and helped improve it by translating,
  testing and developing it.

21
EYEOS 1.0

• After two years of development, the eyeOS
  Team published eyeOS 1.0 (on June 4, 2007).
  Compared with previous versions, eyeOS 1.0
  introduced a complete reorganization of the code
  and some new web technologies, like eyeSoft,
  a portage-based web software installation system.
  Moreover, eyeOS also included the eyeOS Toolkit,
  a set of libraries allowing easy and fast
  development of new web Applications

22
EYEOS 1.1

• With the release of eyeOS 1.1 on July 2, 2007,
  eyeOS changed its license and migrated from
  GNU GPL Version 2 to Version 3.

Combining a browser with a basic operating system
also allows the use of cloud computing, in which
applications and data "live and run" on the
Internet instead of on the hard drive.
With the release of eyeOS 1.1 on July 2, 2007,
eyeOS changed its license and migrated from
GNU GPL Version 2 to Version 3.
23
EYEOS 1.2

• Version 1.2 was released just a few months after
  the 1.1 version and integrated full compatibility
  with Microsoft Word files.

24
EYEOS 1.5 GALA

• eyeOS 1.5 Gala was released on January 15, 2008.
  This version is the first to support
  both Microsoft Office and OpenOffice.org file
  formats for documents, presentations and
  spreadsheets. It also has the ability to import
  and export documents in both formats using server
  side scripting.

25
EYEOS 1.6

• eyeOS 1.6 was released on April 25, 2008 and
  included many improvements such as
  synchronization with local computers, drag and
  drop, a mobile version and more

26
EYEOS 1.8 Lars

• eyeOS 1.8 Lars was released on January 7, 2009
  and featured a completely rewritten file manager
  and a new sound API to develop media rich
  applications. Later, on April 1, 2009 1.8.5 was
  released with a new default theme and some
  rewritten apps such as the Word Processor or the
  Address Book. On July 13, 2009 1.8.6 was released
  with an interface for the iPhone and a new
  version of eyeMail with support for POP3 and IMAP.

STRUCTURE AND API
30

• eyeOS is an open source web
  desktop following the cloud computing concept
  that leverages collaboration and communication
  among users. It is mainly written in PHP, XML,
  and JavaScript. It acts as a platform for web
  applications written using the eyeOS Toolkit.

31

• For developers, eyeOS provides the eyeOS Toolkit,
  a set of libraries and functions to develop
  applications for eyeOS. Using the
  integrated Portage-based eyeSoft system, one can
  create their own repository for eyeOS and
  distribute applications through it.

32

•  eyeOS uses XML files to store information. This
  makes it simple for a user to set up on the
  server, as it requires zero configuration other
  than the account information for the first user,
  making it simple to deploy.  To avoid bottlenecks
  that flat files present, each user's information
  and settings are stored in different files,
  preventing  resource starvation from occurring.

33
The Pros and Cons of Cloud Computing

• Lower-Cost Computers for Users
•  Because the application runs in the cloud,
  not on the desktop PC, that desktop PC doesnt
  need the processing power or hard disk space
  demanded by traditional desktop software. Hence
  the client computers in cloud computing can be
  lower priced, with smaller hard disks, less
  memory, more efficient processors, and the like. 

34
Improved Performance
Improved Performance

• A cloud computing system will boot up faster and
  run faster, because theyll have fewer programs
  and processes loaded into memory.

35
Lower IT Infrastructure Costs

• The IT department could also see lower costs
  from the adoption of the cloud computing
  paradigm. Instead of investing in larger numbers
  of more powerful servers, the IT staff can use
  the computing power of the cloud to supplement or
  replace internal computing resources. 

36
Fewer Maintenance Issues

• Speaking of maintenance costs, cloud
  computing greatly reduces both hardware and
  software maintenance for organizations of all
  sizes

37
Increased Computing Power

• This is an obvious one. When youre tied into a
  cloud computing system, you have the power of the
  entire cloud at your disposal. Youre no longer
  limited to what a single desktop PC can do, but
  can now perform supercomputing-like tasks
  utilizing the power of thousands of computers and
  servers. In other words, you can attempt greater
  tasks in the cloud than you can on your desktop.

38
Improved Compatibility Between Operating Systems

• In the cloud, operating systems simply dont
  matter. You can connect your Windows computer to
  the cloud and share documents with computers
  running Apples Mac OS, Linux, or UNIX. In the
  cloud, the data matters, not the operating system.

39
Cloud Computing Disadvantages
40
Requires a Constant Internet Connection

• Cloud computing is, quite simply, impossible if
  you cant connect to the Internet. Because you
  use the Internet to connect to both your
  applications and documents, if you dont have an
  Internet connection, you cant access anything,
  even your own documents.

41
Can Be Slow

• Even on a fast connection, web-based applications
  can sometimes be slower than accessing a similar
  software program on your desktop PC. Thats
  because everything about the program, from the
  interface to the document youre working on, has
  to be sent back and forth from your computer to
  the computers in the cloud

42
Stored Data Might Not Be Secure

• With cloud computing, all your data is stored on
  the cloud. Thats all well and good, but how
  secure is the cloud? Can other, unauthorized
  users gain access to your confidential data?
