Selecting A Cloud Computing Model

Posted on 13 February 2012 by Tea Server

There are two common delivery models in cloud computing  IaaS and PaaS. They offer users different levels of control to provide software and hardware services on-demand from a remote host.

Cloud Computing Model Selecting A Cloud Computing Model

Automation That Saves Time

Platform as a Service (PaaS) has great benefits for software developers. Clients receive the tools and services necessary for coding and deploying applications without purchasing and maintaining software and infrastructure. It allows the creation of software utilizing proprietary data from applications. Clients can also use PaaS to create applications with common data form. It is good for people with existing data sources, such as customer accounts, and create applications for data use. It can also automate testing and deploying of services. PaaS is not good where applications need higher portability or when proprietary languages have an influence on the development process.

Efficiency With Low Costs

Infrastructure as a Service (IaaS) delivers the hardware and software to power servers, storage, networks and operating systems as on-demand services. IaaS is offered as either public or private infrastructure. Public is outsources as shared resources on a self service basis over the Internet. While private has the characteristic virtualizations but does so on a private network. Clients receive resources, dynamic scaling with the ability to accommodate multiple users on a single piece of hardware.

IaaS benefits clients if their demand for infrastructure is not steady or if companies don’t have financial resources for scaling hardware. Regulatory compliance make the outsourcing of data storage and processing difficult for most users of IaaS. They are also disadvantaged if a company needs a high level of performance with its own infrastructure.

Do Check: Cloud Storage and Cloud Computing

Practical Use

One example of successful PaaS user is Menumate. They are an Australian point of sale as we as a  hardware and software provider. They use PaaS for their legacy applications. They were able to centralize and integrate a somewhat outdated in-house software toolkit by adopting PaaS. The service provided them non-functional requirements of significant infrastructure, connectivity and security so they could develop more functionality. They were also able to take advantage of existing integrations and automated deployment tools that PaaS offered them during the development process. Some of the legacy applications they migrated where licensure key generation, enhanced case management and label pricing. Using Paas development environment increased the speed of application creation. Without the service the process would have been costly.

Live Smart is a producer of books and online diet programs. They operate the interactive online community Beyond Diet for their program users. In 2008, their site averaged visits of 300,000 viewers per day with spikes of up to 1,000,000 users a day. They needed an infrastructure that was low-touch and highly scalable to handle spikes. IaaS gave them the correct solutions for their marketing strategy. IaaS acts as their Linux and Windows administrator. They made changes as needed and responded to downtime. The service gives them the ability to focus on their core business. Their final decision to stay with the service has reduced the cost and increased flexibility compared to dedicated servers.

To sum up, control is the major difference between the two services. PaaS offers no control for the user with most implementation and control of applications handled through PaaS vendors. While Iaas users have total control but need a stronger technical team to handle the responsibilities of maintenance and security.

Predicted 2012 Cloud Computing Trends

Posted on 26 January 2012 by Tea Server

Late last year, the cloud computing industry drew the proverbial line, as did all other industries. 2011 was definitely not an easy year by all accounts, with the global economic downturn continuing to affect major players the world over. The past year also saw Asian markets and producers climbing even further up the tracks, especially with respect to the computing and information technology industry. As Asia continues to invest in developing and researching new facilities, services, features and products (that the rest of the world will only likely see in a few years from now), the questions we all pose about the future remain valid. Cloud computing is definitely still an up-to-date revolutionary trend that is shaping the way we do business and even the day-to-day way in which we approach information. What, then, are the major trends that experts predict will explode in 2012? According to some of the most educated voices on the matter, 2012 will not be an explosive year, but one which will deliver ‘more of the same’. But what exactly does that ‘the same’ entail?

Cloud Computing Trends Predicted 2012 Cloud Computing Trends

Look out for the Asians

According to the experts, businesses that are based in Asia will continue to migrate toward the cloud, as they seek to leverage experienced serviced providers with key positions in critically strategic information technology positions. The cloud has already proved its usefulness and efficiency in this respect over the past few years. In addition, larger businesses will continue to or initiate their expansionist trends. Going global in the cloud industry means service providers that are based in the United Kingdom or the United States of America will rake in a hefty part of the proverbial pie.

Move Toward the Mainstream

A subtle trend dominated the cloud computing services market for as long as it has been around. It is so subtle that we even included it in the previous sentence, without you even flinching. Everything information technology-related is becoming a service these days. This trend will become so pervasive and ubiquitous that, experts argue, people will stop referring to the cloud as ‘the cloud’. It is already a common occurrence to base most of your activities online. Some of the more astute industry observers may have noticed that some of the largest players on the Internet scene have been creeping into the cloud industry in recent years. This trend will continue to grow and develop, while quality services will attract increasing amounts of capital, as mainstream, non IT-involved businesses will want to keep up to speed with the latest tech trends.

Security Alerts in the Cloud

The one moot point when it comes to the cloud is the issue of its security. This will continue to be a hot topic, up for debate, since Internet security measures are on an ever-increasing trend of becoming tougher and tougher. Major companies set to implement the cloud will be particularly concerned with the security of their data, as well as with any possible breaches of local and international security regulations.

Can you Trust Your Network Provider?

Posted on 25 January 2012 by Tea Server

Nowadays, businesses rely on high speed communication in order to access vital resources at the drop of a hat. The demands of modern business mean that the task of managing the costs and complexities of an extensive network are often outsourced to a managed network provider. So how do you know your network provider is up to the job?

Internet access, cloud computing and VoIP services all need a specialist provider to manage the network, ensuring the business is fully functional at all times. A flawed network can slow a business down, hampering the workflow of staff.

A broken or faulty network can potentially cost a business much more than time alone; if an organisation utilises VoIP and relies on cloud access to run effectively, then a broken network could mean no communication with the outside world, and no access to important documents.

Network Provider Can you Trust Your Network Provider?

Clients and customers will not be happy if your business is unreachable, and persistent issues could lead to your reputation being damaged, a drop in sales and even a decline in long-term client retention. Your network service provider should have a continuity plan in place in order to avoid any unwanted downtime. If not, then that provider is best avoided.

Sensitive information is often stored on cloud networks, which makes protection and security of the up most importance. Physical theft is also a genuine issue, particularly during this time of recession. The provider’s data centres should have 24-hour security, to deter thieves and vandals, in addition to stringent systems security to prevent hacking, denial of service attacks and other cybercrime activities.

Naturally, successful businesses will grow with time, so a provider should have the ability to grow with your business, seamlessly integrating new technologies and new office locations into the network. If a service provider can’t grow with your business and keep up with modern technologies, again, then give them a wide berth.

Finally, and crucially, any trustworthy network provider should offer roundthe-clock support and resolve any issues efficiently and effectively. A business must be sure of the level of support they will receive. If a company pays good money to a managed service provider, then the service must be provided in a way that allows the business to run without a hitch.

Do Check: Voice: More a Service than a Protocol

A network service should be functional and accessible, and provide uncompromised usability. If a provider is not up to the task, it’s probably time for a business to assess its options and perhaps look elsewhere to satisfy its managed service needs.

SOPA / PIPA / ACTA Ultimate Doom

Posted on 24 January 2012 by Tea Server

LAHORE POST

Piracy is an issue that the pirated fight with rigor against pirates who defend it with vigor. On the one hand we have a community that watches movies, TV shows, listens to music, plays video games and utilizes software without paying a single Rupee to the creators and on the other hand we have creators who have begun over charging for content that was once included in an affordable package (e.g: Bonus content DVDs).

The logical thing to do would have been to find some sort of middle ground as attempted by EA’s Origin store, which has brought their prices down to a relatively affordable range. But instead we as part of the global community are faced with SOPA and PIPA, which is like bombing a country because there might be a terrorist or two in there (sound familiar?).

Normally, I prefer talking about the big picture of how things are in Pakistan and how they can be changed for the better.  SOPA is no exception. We have, on our hands, an unreasonable situation. SOPA and PIPA, Stop Online Piracy Act and Protect IP Act respectively or the Full Title: Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011. The details of which can be found on Wikipedia.

I will spare you the grim details for your own leisure part and will dive right into why this is a terrible idea. I won’t even talk about how this is effectively the US government killing flies using cannons, I want to talk about what these ominous rumblings might portend. This is seen as the end of freedom on the internet. If this falls through, your future browsing experience will be greatly affected (discussed in detail later). Numerous websites and the bigwigs of the industry have already addressed what this means for the internet in general, but what is most important to Pakistan is the end of an industry.

Allow me to elaborate. Pakistani bloggers, websites and e-commerce businesses rely heavily on AdSense for revenue. A very healthy livelihood can be earned online if one is so inclined. An idea that is becoming increasingly popular amongst the youth of the nation as it offers revenue earned by generating traffic to their page and they are compensated through the ads placed on that site. With SOPA in effect, this would mean these blogs and sites will be subject to entire hit squads out to shut down and prosecute anyone who is
suspected of using copyrighted material. The most egregious case being a woman fined $1.9 Million for downloading 24 songs. Let us not ponder over what mathematics lead to a situation where the RIAA demands $80,000 per song from a mother of four but understand that this system will spare no one.

This problem becomes our problem when we realize that users cannot always generate their own content, for a 1000 word article, they might have to look at images.google.com for some supporting images or link some YouTube videos or share your favourite song. All of which are going to become offenses punishable for up to 5 years in prison under SOPA. This is inevitably going to drive away business which is going to hurt how things are done in Pakistan.

Megaupload is also a good example of what this mechanism can do, where employees were arrested and the company’s assets were seized. This affected legitimate users as well, those who paid good money for an account and never used it for piracy had their accounts seized along with their membership fees. Without such unremitting monitoring, AdSense and other assorted Ad services will not recognize non SOPA compliant sites as worthy and a huge chunk of web content will go unpaid.

Another consequence that is direr in my eyes is that the next step would be the implementation of pay-per-use internet; which seems inevitable. This might be great news if we are discussing cloud computing but just the worst thing ever if we are discussing our modern
day usage. This will enable a mechanism that allows for pay-per-use charges for internet consumption. If our current usage is a buffet, we will start ordering from a menu soon (hint: buffets are cheaper and more satisfying). Imagine going online but having access only to e-mail, because your package plan does not include web browsing or streaming. This is a very real possibility as it will make monitoring easier, during which process it will make it easier for organizations to charge more for services that you are currently getting as part of your monthly internet usage. This is the equivalent of getting a separate meter for the kitchen and a separate one for heaters.

Additionally, there is a treating going around by the name of ACTA (Anti Counter fitting Trade Agreement) which is a global phenomenon and it will encompass all signatory nations. Which means all of us. Everyone with an internet connection.

So we as a nation are poised to be on the losing end and we are the quietest on the matter so far. There will not be a truly free forum for sharing ideas. News sites, tech sites, blogs, start-up sites and the likes will be run out of business and an entire generation of ideas will go to waste. The purpose of the article is to encourage readers to do something about it while at the same time, to be aware of what the future is.

Author’s notes:

1- This is not “A coin lands on its Edge” because there I propose solutions. Here, the solution is not one I can expertly comment on.

2-  Those who stand to make money from prevention of piracy are already making money (I don’t think these musicians are what we would call poor). These are corporate manipulations to milk every last penny out of the public’s pockets and to hell with those who cannot pay.

3- Our protests will only strengthen the argument against this bill as it is being processed on the 24th of Jan. It has been vehemently protested by the world, but Pakistan has no share in the protest, our voice WILL help.

4- Once this is crushed, it will be back later, dressed up better, in glossier words and modified terms to satisfy the corporations but we have to be aware every time.

Fighting for the Future of the Internet

Posted on 20 December 2011 by Tea Server


The online world has been all aflutter in recent weeks over the introduction of two pieces of legislation in Congress: the PROTECT IP Act in the Senate and the Stop Online Piracy Act (SOPA) in the House of Representatives. As PROTECT IP already passed in the Senate, last week the focus shifted to the hearings on SOPA and the fate that such legislation could have on the internet.

Both bills attempt to thwart online piracy and protect copyrighted intellectual property. However the way that Congress is trying to do this is by giving law enforcement and individual property owners the right to go after websites that might infringe on copyrighted materials and shutdown the website, prohibit other businesses from serving the sites, barring search results to the websites, and requiring service providers to block the websites. This may seem reasonable at the outset, but the results are far more complicated. The implications of such enforcement, and especially the individual right of action that SOPA allows, may mean that attempting to regulate the internet in this way threatens freedom of speech and information issues, places too high a burden on internet companies to comply, and fundamentally changes the way the internet will function within the United States and make it more on par with such beacons of freedom as China, Iran, Saudi Arabia and Ethiopia. It is these consequences that are leading many opponents to claim that SOPA will actually break the internet.

Last Thursday the House Judiciary Committee held a session to mark-up the proposed bill. The main focus was the 55 amendments proposed to the original bill, most of which try to soften the impact of the bill and find an acceptable middle ground between proponents of the bill, including the Recording Industry Association of America and the Motion Picture Association of America, and the incredibly long list of internet-based companies and activists who are adamantly against the bill.

Throughout the hours of debating the amendments (all of which failed), netizens tracked and discussed the developments online. It is estimated that over 150,000 people from 150 different countries watched a portion of the hearings on Thursday through the KeepTheWebOpen.org webstream.  As the bill may determine how the internet functions in the US in the future, what better way of looking at the battle against the bill than seeing how it is being fought online?

The hearings are scheduled to resume on Wednesday, December 21. Follow the developments at KeepTheWebOpen.org.
