Cloud and Realities

A group of technically empowered people with liberal thoughts and creative ambiance has given birth to a community with openness as its icon. This open source group has always stood for building up better technologies and allowed freedom to look at the codes and to change it for more compatible application. This collaborative process has catalyzed the growth of IT to incredible heights and provides more value to the end users

The open source provides a solid foundation to the emerging technology of cloud computing. It is estimated that over 90% of the public cloud are powered with linux and other open source software. The scalability, stability, performance and robustness to cope with the requirements has propelled the cloud computing technology to crest of major application in IT.

Even when IT community rate Cloud computing as the next step towards future, there are a few who do have a spell of ambiguity in the concept of cloud computing. In a very simple sense cloud computing could be conceived as computer resources delivered as a service through network. With the advent of high speed internet and machines with greater capabilities, cloud computing has gained more popularity and has become a cost effective contemporary technology. The end user even taps into the resources offered by the providers even without realizing that they are availing the benefit of “cloud”

The technology of cloud computing is performed at various levels – public, community, hybrid and private cloud. Private clouds can be considered as the modern day equivalents of the mainframe and terminal solution used by organizations in the past. However, private clouds can now be completely outsourced to a host, who ends up providing the required services and infrastructures, While the end user taps into the resources offered by the provider.

As the technology evolves, larger virtual storage areas will become tangible and servers will gain greater performance capability. The mode of communication between the end user and the service provider will get to a new dimension, where all storage will become cloud based.

Redhat the master vender in linux distribution has established its own platform as the de facto standards for open cloud computing

With its API 1.0 release, Deltacloud offers a variety of front-ends, which is to say interfaces through which users make a request to a cloud provider. New is a basic Amazon EC2 front-end, which can be used to communicate with a variety of cloud providers using the popular Amazon Web Services interface. This is primarily intended for users looking to migrate between EC2 and another cloud provider.

These developments has set the stage to a new era in IT

Is Linux, an Unix like operating system?

It is astonishing to note that over the past couple of years there are a few bug of uncertainty among the techno loving generation in conceptualizing UNIX and Linux. Most often Linux is viewed as an UNIX like operating system which is strongly disagreed by “open group, an industry standards consortium” and they weigh it as an attempt to misuse unix trademark. 

UNIX is copyrighted name where only big companies are allowed to use the UNIX copyright and name, IBM AIX, Sun Solaris and HP-UX all are UNIX operating systems. This operating system is mostly commercial in nature. The Open Group holds the UNIX trademark in trust for the industry, and manages the UNIX trademark licensing program.

Admit all the reportage of the argument of all forums and groups, Linux as read from official Linux kernel README file is stated as ”Linux is a Unix clone written from scratch by Linus Torvalds” aiming toward POSIX compliance. While Unix is originally developed by a group of AT&T employees at Bell Lab in 1968 and initially ported to government commercial firms and educational institution. The Unix operating system are complete operating system which has many utilities inbuilt along with kernel the master control program.

Linux is just a kernel and Linux distribution makes it complete usable operating systems by adding various applications. Hence all linux distribution includes GUI system, GNU utilities (such as cp, mv, ls, date, bash…etc), installation & management tools, GNU c/c++ Compilers, Editors (vi), and various applications (such as OpenOffice, Firefox) etc.

Regarding the file system, Linux by default supports and use ext3 or ext4 file systems while UNIX comes with various file systems such as jfs, gpfs (AIX), jfs, gpfs (HP-UX), jfs, gpfs. When comparing the system administration tools and security firewall, Unix system comes with its own tools and products like SAM on HP-UX.for sys admin and ipfilter based firewall. While Linux uses open source netfilter/iptables based firewall. While analyzing on the end user perspective the difference is not big on an average, both uses same shell (e.g. bash or ksh) and other development tools such as Perl or Eclipse development tool.

While diagnosing it from a cost frame Linux is free you can download it from the Internet or redistribute it under GNU licenses. You will see the best community support for Linux. Most UNIX like operating systems are not free (but this is changing fast, for example OpenSolaris UNIX). However, some Linux distributions such as Redhat / Novell provides additional Linux support, consultancy, bug fixing, and training for additional fees.

At the enterprise level linux flavor grids most of the server and cloud platform where RHEL tops the tally. To know more about the advantages of RHEL visit advantages of RHEL

Open source a viable alternative to traditional proprietary software

The dream of a fully open-source enterprise world is not as crazy as it sounds remarked Jim Whitehurst, CEO of Red Hat. It's already happening for Web startups. Plus, "the Amazons and Googles and Facebooks and Twitters are all running open source" he adds and by open source, he doesn't mean Red Hat. This is "broader than Red Hat," he says

When the global trend in the IT scenario emerges with Cloud computing, Service-centric architecture, Data privacy, IT security, Social platforms as a stack of business intelligence and prioritized user experience, the open-source is not viewed as a trend rather a potential enabler to all of these trends.

Jim Whitehurst, CEO of Red Hat to the press states “Now that Red Hat has become the first and only pure open-source company with a billion dollars in annual revenues, his goal is  the death (more or less) of proprietary software.”

He continues "We got to a billion dollars by convincing the world that open source is a viable alternative to traditional proprietary software," Whitehurst told Business Insider. "The next step is to make open source the default choice in this next generation of computing. That's what takes us from $1 billion to $5 billion and beyond."

When the global happening has set such a landmark, the hesitation in the choice of the technology that ought to rule the world and industry is baseless. So be prepared for the reality
