Cloud Computing in India: A Long way to Go

According to a business report " Brazil, Russia, India and China still lag far behind developed countries in policies considered critical for the future of cloud computing, but each made some progress over the past year, a U.S. industry group said on Thursday.

The Business Software Alliance, which represents U.S. industry heavyweights such as Microsoft Corp, said the BRIC nations all came in at the bottom half of 24 countries surveyed in its second annual cloud computing report.

Brazil moved from final position to 22nd with a tally of 44.1 out of a possible 100 points.

China, India and Russia each also rose two slots with scores of 51.5, 53.1 and 59.1, respectively.

Cloud computing refers to providing software, storage, computing power and other services to customers from remote data centers over the Web.

Demand for cloud-based software is rising rapidly because the approach allows companies to start using new programs faster and at lower cost than traditional products that are installed at a customer's own data center.

"The cloud is really the hot sector of IT right now," and U.S. companies have a big interest in countries harmonizing policies instead of chopping the cloud into pieces, said Robert Holleyman, president of the Business Software Alliance.

At the same time, the aggregation of massive amounts of data in large data centers "creates new and highly tempting targets" for cyber attacks, making it vital that both law enforcement officials and cloud providers have adequate tools to fight the intrusions, the BSA report said.

Lack Of Properly Trained Cloud Professionals Threaten Industry

John Omwamba shares a growing concern Data from job aggregators focused on the cloud computing market reveals that some areas stand out as the best places to find cloud computing jobs around the world. The irony is that employers in some of these areas are finding it difficult to find qualified people to fill the cloud positions which are apparently paying in the upswings of $100,000 plus, per year. While this is a salary to die for, the fact that no suitable candidates are showing up is raising questions on whether the academic pipeline is releasing enough techies for the evolving cloud space

Dangerous Gap

Analysts have raised a serious alarm pointing to the danger of heading to a future where the market will experience a boom in cloud computing job opportunities with no properly qualified Cloud Professionals to fill them. Indeed a Microsoft sponsored IDC report shows that cloud jobs will shoot up by 26% every year through the next two years starting 2013. In 2012 alone, approximately 1.7 million jobs fled by a void of qualified skills to fill them. According to IDC, the turn of 2015 will witness a critical swell in IT jobs throughout the global scene, pushing to the 30 million mark.

Way behind

Sadly, IT professionals around the world are seemingly behind the cloud revolution and have not actually been equipped with skills matching what the cloud computing environment is demanding in order to succeed. There is a significant danger here because the consequences could include poor products coming out of cloud factories, not to mention security risks and system vulnerabilities that will threaten millions of businesses around the world who rely on cloud computing to perform their business functions.

Much of the frustration is driven from the approach businesses are taking towards cloud computing. Most businesses are increasingly recognizing the cloud as an integral part of their systems, with majority (half) terming it a priority area. Two thirds are making plans to implement relevant cloud solutions in their enterprises or are already going through the implementation process.

Certification and experience rate poorly

Businesses have acknowledged that while they would love to fill cloud positions in their companies, their fear is drawn from the reality on the ground which points to a scenario where those who claim to be good in the craft lack proper training, experience and credible certification. Recruiting companies are consistently creating systems to aggregate the best cloud jobs. The challenge still stands tall: that there are no qualified cloud professionals to touch these jobs.

Glaring Opportunity?

While the loneliness of a company searching for skills that cannot be found speaks volumes, there is a glaring opportunity that is lighting up somewhere in the uncovered clouds. This is no doubt the time for academic institutions and other stakeholders to seize the moment and introduce practical, full time cloud courses that will then bake the next cloud brains whom the industry needs so badly if the birth of revolutionary cloud products is to be sustained heading into the future.

Embrace the cloud computing revolution – with caution

According to a post by Dan Gillmor " Google recently launched its high-end Chromebook Pixel, and like previous Chromebooks this notebook computer makes a distinctly 21st Century assumption: that users' data, work and play belong mostly online, not on their own computers. Google isn't alone in pushing this notion, but it's the most powerful evangelist for the shift to what tech people call the "cloud" and away from "local" storage. Call me unconvinced. Deeply unconvinced.

Image Source

The cloud evangelists have an alluring pitch. First, they say, we can now count on being connected as much of the time as necessary. Second, these computing and data services becoming a utility like electricity – easier and safer to run from remote servers than on our local systems.

Like almost everyone else, I use lots of cloud services. They start with everything I do from a browser, such as search, microblogging (Twitter), multiuser games, etc. They also include my email (I store a few weeks' worth of messages in an online system that shows me the same inbox and folder structure no matter what computer I'm using) and calendars, but in those cases I'm synchronizing the data to the local machine. And I use several online sites to back up my music and important documents.

But move everything to the cloud, and use it in an on-demand way? No chance, at least not now – and probably not ever.

For one thing, web-based applications simply can't match the power and flexibility of native desktop software, at least not yet. Google Docs do many things well enough for non-complex tasks, but that's not good enough when I need, say, the track changes feature in Microsoft Word or its Linux equivalent, LibreOffice Writer. Online applications are getting better, and they can do some things the offline ones can't, of course; there are tradeoffs that over time will make the online offerings more compelling. And as Google and other web-based software companies make it possible to work offline – you can do that now with Google Docs – one more advantage of local computing will be mooted.

Cloud Computing Benefits: Both Financial and Operational

According to an article Two primary benefits of cloud computing are financial and operational

Consider the financial benefits of the cloud.   A survey by KPGM found that 70 percent of businesses say that the cloud has already brought them significant efficiencies and cost savings.

Rick Madan, executive director of network services for TEKsystems, said that “the total cost of ownership of software and hardware goes down for end users since they are removed from the business of buying, licensing, and maintaining associated assets.  Furthermore, the revenue-and-service premise for cloud providers is built on a ‘pay as you go’ model so as an end-using company, instead of getting bogged down in the sunk costs of servicing debt related to sometimes idle IT processes and resources, the cloud model allows you only pay for those actually utilized by the business at any given moment.”

There are operational benefits from the cloud too.  The introduction of cloud computing can be transformative to the operations side of the business.  Tasks that focus on the lifecycle management of hardware and software often get offloaded from the business to the cloud provider.  Tasks like change control, versioning, upgrades and updates, release management, storage, process job management, and data center mirroring are either eliminated or greatly reduced.

IT industry to focus on mobile tech, big data, cloud computing

According to the NAASCOM The IT industry will focus on internet and mobile technology, big data and cloud computingtechnologies for speedy growth in order to achieve USD 300 billion revenue by 2020, Nasscom today said. 

"The IT industry has a vision and aspiration to aggregate USD 300 billion revenue by 2020 by focussing on IT products, Internet and mobile technology, big data, cloud computing and 3G/4G technologies, for speedy growth," NASSCOM Expert Committee Chairperson N R Narayana Murthy told reporters here. 

To achieve the milestone, NASSCOM in July 2012 set up an independent Expert Committee to address key needs of the industry in order to help realise Vision 2020. 

The findings and recommendations of the committee report address the growth opportunity for IT industry by size and potential as well as key enablers for NASSCOM to partner industry in building future growth opportunities, he said.   For complete story see here 

How Cloud Computing is Affecting Authors

According to this, The advent of the Cloud is a verifiable game-changer when it comes to literary workings. As opposed to the pre-Cloud era, writers had mostly always needed to rely on publishers to get their works printed, sold and achieve success. The Cloud allows authors to bypass publishers, as it offers copious amounts of free space to which their writings can be published. The Cloud does seem to be changing the writing game as we know it. The question now is: what is the role that the Cloud now plays in Publishing?

A free platform

Thanks to the Cloud, various forms of media are beginning to find their way on to the web. Whether it is music, videos, articles and even books, the Cloud offers a platform where these pieces of media are able to be posted and presented with nothing more than clicks of a button.

As opposed to doing business with publishers and their companies, some authors may find solace in the freedom that the Cloud offers. First off, there is no need to invest one's own money in working with these publishers, as the Cloud is a free platform. As such, authors and writers are able to publish their works themselves. These works will always have a place in the multitudes of spaces in the Cloud. For cloud computing implications on authors, please read here 

Cloud tools for productivity enhancements

Chris Moyer shares " When you're in a remote working situation, the constant communication and whiteboard mock-ups that are normal to an office environment become complicated. Fortunately, there are cloud and Web tools available that can help with this issue. While there are many tools for each situation, these are the applications I've found helpful in my life as a remote development manager and programmer.

Flowdock for team collaboration

Flowdock is a Web application designed for collaboration that provides developers with a central location to communicate with other developers and check in on their work during the day. Flowdock was purchased in February 2013 by Rally Software, a Software as a Service application lifecycle management tool provider.

A chat room with extras, Flowdock integrates with other services, including trouble ticketmanagement systems, wikis and even Twitter and RSS feeds. Flowdock is completely Web-accessible and available via several mobile applications. It allows you to provide that "water cooler" atmosphere, but the caveat is that the entire team has to use it daily for it to pay off.

There is no one super-tool that can manage all situations.

At Newstex, we use Flowdock to monitor development team members' activity, and we require them to remain logged into it during all billing hours. Flowdock helps me and my team members to do the following:

Keep a complete history of the project, reducing the time spent on documentation

Tag and search conversations, so one can easily go back in time and find out what was decided to do about that pesky little bug or feature request from a client

Integrate with Twitter to monitor social media to find people talking about the company and even to make replies directly to them or comment to your users first

Integrate with continuous integration and code repository systems to give all developers a single dashboard where they can see what's going on in the workplace

In short, for Newstex, Flowdock is essential to high visibility within the remote workforce.

Skype, Google Hangouts and VoIP for better conference calls

Skype and voice-over-IP (VoIP) are key communication tools for Newstex. We've traditionally used Skype, now owned by Microsoft, for all our voice calls, but recently have been switching to using VoIP services to provide us with a clearer calling experience.

To give each development team member parity, make sure your conversations feel like you're in the same room. Usually, traditional phones can't do that. For VoIP, we use OnSIP, a VoIP cloud service, and give everyone their own extension so they can be reached. VoIP's high-definition voice capabilities allow us to have easy-to-hear, one-to-one, ad hoc meetings and scheduled conference calls. While emails may work for detailing instructions, much more can be communicated in quick, real-time conversations with people. Think of these calls as a replacement for walking over to someone's office and having a quick chat about something you're working on. For few more tools and complete story see here.

Cloud Computing can Transform India

Why Like Cloud Computing - Here is an explanation from a Digital Managing Editor

Despite some raging concerns, this is why Jigsha Desai  digital managing editor  still  likes working in the cloud. Here’s why:

My personal laptop is more than 5 years old. It’s outdated and has no CD/DVD drive (a long story about a mug of tea and my keyboard and the tea winning). But that hasn’t stopped me from using recently updated programs at no cost.

The Google Chromebook Pixel

I wrote my first edit of this column in Google Drive. In fact, copies of all my written work may be found in Google Drive. When I need to prepare anything I turn to it first. Think of Google Drive as your “My Documents” folder on the Internet. The beauty is I can create or access these documents from anywhere I have a computer login, or even my smartphone!

The ease of Google Drive has made it such that even when I am on my Apple machine at work, I turn to it for drafting a document or a PowerPoint-style presentation.

Google is banking on the cloud computing experience with the rollout of its new Google Chromebook Pixel. The new laptop by Google promises an innovative experience with a touch screen and “crisp text, vivid colors and extra-wide viewing angles.” It’s also offering one terabyte of cloud storage free for three years. Any computing work that requires creating documents, presentations and spreadsheets will be done via Google Drive.

Another one of my favorite cloud computing experiences is Dropbox. The service acts as a virtual folder you can access anywhere and with any device, just as long as you are connected to the Internet. I’ve saved photos, PDFs and large files on Dropbox that I can later access on my home and work machines, smartphone or iPad. The beauty of Dropbox is you can easily share your files with others. (If you'd like to join Dropbox, consider using my referral link.)

My favorite photo editing program in the cloud is called Pixlr. This free Web service mimics the experience of Adobe Photoshop and allows you to create images and crop, edit and tone photos easily.

Cloud computing has enabled me to work more efficiently without having to spend much money, which in my opinion is always a good thing.

Compressing data for the Cloud

By compressing data and eliminating duplicate copies, an Amazon Web Services customer can decrease by as much as 50% the cost of moving data out of the cloud, say spokesmen for Silver Peak Systems, which on Thursday started offering a virtual appliance to do just that.

According to a post in information week It can be critical for some public cloud users to reduce the amount of data exported from the cloud. Several vendors, including Amazon, charge nothing for the bandwidth to upload data. But they charge by the GB when it comes to downloading. AWS, for example, charges $0.12 per GB after the first free GB to move data out of S3 to a destination on the Internet, a charge that can quickly mount up. Ten terabytes would lead to a charge of $1,200, and truly big data would rack up multiples of that figure. That gives many cloud users second thoughts as they contemplate the cost of moving data out of the cloud, a possibly intended consequence of that pricing approach. Silver Peak has launched its Virtual Acceleration Open Architecture as an Amazon Machine Image appliance available in the Amazon Marketplace, ready to be activated in the cloud for a given workload.

Cloud Computing : Testing the Waters

Cloud Computing Country Perspective: New Zealand

According to a report " It’s a cliche but in cloud computing we really are missing the wood for the trees.

Perhaps unfairly, I blame IT vendors for pushing ‘x as a service’ ad nauseam. Most people hear all those tech terms and tune out.

Yet, cloud computing as a business strategy has the potential to be a game changer. Businesses, politicians and policy makers have to understand that cloud computing represents table stakes for international competitiveness today, a necessity rather than tech blah blah.

Image Source

Conditioned by thinking in physical terms- our small market and geographical isolation- the transition to digital and Internet thinking is not easy. It’s made worse by our collective failure to lift our sights from tech talk to strategic thinking, both at a business and country level.

Cloud computing does offer potentially significant benefits for the intended audience of IT vendor-speak, enterprises. All the talk of reduced operational costs, shift from capital expenditure to operational costs, access to best practices, reduced time to market, and increased agility/flexibility is true. But that’s missing the wood for the trees. Worse, we are drowning in a sea of IT vendors proclaiming how they have the bestest and truest cloud solution.

At the most fundamental level, cloud computing is truly about enabling new business strategies.

It is about New Zealand overcoming physical limitations of market size and the tyranny of distance. For details see here

Cloud Architets in a Conversation

One of most practical ways to understand what a cloud architect does, is  to talk to people in that role? In this conversation, a pair of cloud architects, Oracle ACE Director Ron Batra (product director for cloud computing at AT&T) and Dr. James Baty  (VP of Oracle's Global Enterprise Architecture Program) , talk about how cloud computing is driving the supply-chaining of IT and the democratization of the activity of architecture, about the increasing velocity of IT, and about why architects need to up their game to succeed in a cloud-driven world.

Image Source

B. Rhubart	It seems logical to start by asking each of you to describe a little bit about what you do. Ron, let's start with you.
R. Batra	I'm a director of products at AT&T, and I focus on AT&T's public cloud services. Currently, I lead a product called AT&T Cloud Architect, which is the infrastructure of the service, and I worked with a few Cloud products prior to this role as well.
B. Rhubart	Jim, how about you?
J. Baty	It's a good question. At Oracle, I work on enterprise architecture and try to understand and build methodology. For the last several years, I have been working on methodology for cloud computing and dynamic infrastructure. I suppose that a simple way of looking at that is, it is pretty straightforward, old traditional-style architecture, but at the same time, the analogy I like to call on is the difference between building a car and building a factory for cars. A lot of what we try to do in cloud computing and the architecture associated with it is construct meta-architecture, these fields of resources upon which applications are dynamically developed and deployed.

Describing Cloud Computing Models

Cloud computing is catching the public attention. It has become a key buzzword on the lips of online population and every IT professional in the recent days. This trend is expected only to grow, as more and more cloud applications and solutions enter to the consumer market.

Image Source

Cloud computing has been in existence for quite long, offering different types of cloud computing solutions – called cloud models. Each model has a unique value proposition, helps provider to develop a different line of business, and offers consumer a variety of service options.  Some of the major or popular cloud computing are the following.

• Cloud services in the web- these are the solutions that end-users are most fascinated about. Online storage solution like Dropbox, have made cloud computing to reach out to end-user in greater depth. In simple term, these services provide one or more web functionality for the end user say, email, word processing , APIs and like
• Software as a service- This has been in action for longer time it is realized by large public. The reason for this is that earlier SaaS applications were addressed at business enterprise and included offers in the domains of HR, CRM and ERP functions. SaaS services allow numerous customers to access a given application, while providing greater flexibility and agility to all of them
• Platform as a service-  This PaaS is addressed at application and solution developers. Under PaaS configuration- the user actually manage the applications and but do so using the infrastructure provided by the cloud provider.
• Utility in the cloud- Essentially include cloud storage options available to users on demand
• Managed cloud service – This model was the pre-runner to all cloud computing model operating today. In this model, it is actually the provider that utilizes the application, not the end user. Anti-spam services are an example

 Cloud computing services are on the rise. They are expected grow, expand and change further in the coming days. Cloud computing has also become a great platform for innovative solutions and entrepreneurial ventures. As such more businesses are implementing new cloud solutions and new range of services are being designed and offered.
