Let's bring this full circle from Part I and II. With regards to the future viabilty of cloud computing .... there are questions to be answered and there are issues to be considered. But there also advantages and opportunities too. You need to understand the whole picture to draw an informed conclusion.

Repeating the questions from Part I:

* With so many companies rushing to announce their development in cloud computing /SaaS/PaaS in 2009, is cloud computing really economically viable in the long-term?

* Will large enterprises and Small and medium businesses actually go in for cloud computing and virtualization?

* What will be the benefits and problems associated with the same?

* Which industries are more likely to be the front-runners in cloud implementation?

I believe as more companies continue to develop and push lots of money into cloud computing technologies .... we will see both large and small businesses sign on. As the supply increases, smaller companies can take advantage as the costs will decrease. For larger companies, they will see other benefits of this such as disaster recovery, uptime requirements, and quicker delivery to worldwide customers.

When looking at the benefits and risks of this technology I think it largely depends on whether the cloud is public or private. Private clouds offer lower risk for companies but at higher cost due to the entity footing the entire bill for the technology, while public clouds such as Amazon offer lower costs but more risks due to private information being saved on public systems. The benefits of both are similar, if done right. Companies will be able to take advantage of better uptime, reduction of downtime due to failures, and improved availability to customers.

Any industry that pushes information to mass communities spread around the world will be the front-runners. These would mostly be media companies such as news outlets, with their main focus of getting information out to the customer the fastest. In an example of the news, the company who can spread a story the fastest will get more readers. So using this technology to get the story to the customers around the world the fastest will have more readers and benefit from cloud computing.

The advantages of this new model are clear and massive. The customer still has full control of their services via various web admin portals, but they now don't need to buy the hardware outright, house it in a rack, pay for the power, the air cooling, the upgrades, the maintenance, the expensive engineers to support them, the replacement of hardware, the list goes on.... They get to pay for what they want, when they need it. Just like water from a tap, or electricity from the socket.

Wi-Fi was probably one of the most revolutionary transitions in modern times. Before the advent of Wi-Fi or wireless computing technology, users were tethered to their desks, routing everything through a LAN line and restricted in where they used their faster and more powerful computing technology by how long their cables were. Wi-Fi changed all that. Suddenly, you had a mobile network that allowed people the freedom to roam and still connect to the Internet and their emails.

A sociological transformation

It is easy to underestimate the impact of wireless computing. It has become a common sight to see caf?s full of people all connected up to a server, yet not a cable in sight. An entire business has grown up around wireless computing - the Internet cafe - that lets anyone, for a small charge, piggyback the establishment's Wi-Fi connection and surf to their hearts content. It is even possible to connect wirelessly using a mobile phone - a situation that would have been unthinkable 25 years ago when you were lucky if you could connect to another phone number using the first mobile 'bricks', let along the fledgling Internet.

It has released the constraints of an old system of doing business. But how does wireless computing actually work?

There are two types of what has become known as 'wireless' Internet - either connection through a router (your standard Wi-Fi) or through the mobile phone network. Wireless routers are the most common form of land based system, and are fundamentally a small connection box that allows a signal to be shared between several computers. Basically, computers 'tap in' to the signal, which can be made even easier by adding a wireless interface card. These usually come as standard with most new laptops, but can be bought as a separate add-on. USB routers and dongles also give anyone the power to be able to tap into any wireless signal, creating their own 'access points' through which the computer can send and receive network data.

Another key component of wireless computing is the actual hardware itself, namely the laptop. There is some contention as to who actually invented the concept of the laptop, but most cite Adam Osborne as the originator of the modern day laptop in 1981, although the 'clam-shell' design was attributed to William Moggridge and developed for GRiD Systems Corporation in 1979. It is difficult now to imagine life without laptops, yet it has only been a little over 30 years since their original conception. But probably the biggest influence on wireless computing was the development of WAP for mobile phones, allowing anyone to connect to the Internet using their mobile phone technology. Today, we feel short-changed if our mobile phone can't connect to the Internet on demand, 24/7.

What future for wireless computing?

The question of wireless computing's future is uncertain. Many believe that wireless computing has reached its full potential - we now have almost universal coverage thanks to a global satellite system creating a web across the world with very few 'blind spots'. Smart phones are feature-rich and future-proofed to a certain extent, and laptops are smaller, lighter and more processor powerful than ever. The only area that can really see any form of development to enhance wireless computing is in the field of battery-life. The most up to date laptops and Netbooks can achieve up to nine hours on one battery, but after that you are still forced to tether up to a power source to keep your laptop running - hardly a 'wireless' situation by any stretch of the imagination. So for wireless computing to move to a new level and give us true autonomy and control about where and when we use our computers, manufacturers have to address the knotty problem of that infuriating 'low battery' symbol. Perhaps then we'll have truly wireless computing on the go.

Are we entering a technological revolution of futurist forecasting aided by artificial intelligence, and an abundance of information, which will better help us make decisions? Not long ago, someone mentioned to me the incredible exhilaration of innovation in the transportation sector and the personal tech sector. Whereas, I do see an incredible amount of forward thinking in the personal tech sector with the iPhone, new tablets, touchpads, e-book readers, 4G wireless smart phones, and human kinetic interfaces, I don't see the revolution of innovation in the transportation sector.

Perhaps, this is because the consumer is overwhelmingly enthralled with the new personal tech devices available, and since the devices don't cost that much, everyone is getting one, or perhaps even several, and it's not just the first adopters, it has totally entered the mainstream now. You don't have to be a transportation field editor to see that there is some innovation in the transportation sector. And yes the personal tech sector with GPS devices and computer interfaces with hybrid vehicles is interesting. But it's not really a revolution.

We've had bio diesel vehicles since old man Diesel first used peanut oil to run his first vehicle. We've had electric cars since the 1900s. And fuel-cell technology dates back to pre-1970. So, I'd say that the transportation sector revolution that some of these Futurists speak of, is slow in coming. And I think America is ready for now. What's the holdup?

Now then, I've read all the research articles and prepared studies, the books, articles, audiovisual presentations, and even listened to speeches at top-notch colleges, online, and I've probably scanned over more power point presentations than I care to admit. And yes there are lots of other products and far too many futurists, consultants, and innovative experts offering their services to help with patents, designs, and graphic renderings so that inventors, innovators, and entrepreneurs can reach their potential clients, organizations, and government procurement departments.

Still, I say to you this isn't good enough yet. And talk is cheap.

It is important for an idea to have a spokesperson and someone that can relate to the general public and help them envision such innovations which may create alternative futures for their products, or services but it's really more than that, and I'd say about now the revolution in transportation is needed. We need to bring these new materials to make over the road trucks, cars, and even military vehicles lighter so they use less fuel, and are safer. We have most of the technology we need now, but folks say it is a matter of cost, even though these new materials are cheaper to make.

The real issue is one with tooling, and supply chain. It takes a lot of time and cost to retool, and then you need a return on your investment. It seems we have too many people running around pretending to be professionals, and belonging to far too many professional organizations to be of any real use in innovation. What we need is to get the regulations out of the way of entrepreneurs and allow them to do what they do best; inventing and innovating. Sometimes I feel as if the innovation consultants act more like gatekeepers, and barriers to the very technological revolution they claim to be one with. Please consider all this.

What is Remote Computing Technology in General?

Remote computing is becoming a popular trend when it comes to computer usage. This is a type of technology that focuses on allowing applications that are considered to be "GUI", or "Graphical User Interface" to run and operate in a remote manner on a particular server or computer at the same time in which it is being viewed, ran, and operated at a base location. There are many unique features and capabilities that make remote computing available even for the home computer user. The extent in which your remote computing software will operate will depend on the version that you elect to implement. Here, you will learn more about remote control technology, as well as how it is used productively.

Popular Remote Software Applications

There are many different solutions when it comes to remote computing software. Most of todday's remote administration solutions (as they are sometimes called) focus on bandwidth efficiency and high performance. They often also allow for the sharing of files between two systems. The protocol will communicate from a base computer to an external computer.

1. Remote Desktop Protocol - This is often referred to as "RDP" for short. This is most commonly discovered in Windows operating systems. This specific language allows sound devices and files, as well as printing to be used and done from one computer system to another.

2. X Window System - Many applications that are considered to be "local" are often used when it comes to this type of remote computing, which incidentally, is also referred to as "X11". X Windows is seen in Unix computing environments.

3. Virtual Network Computing - Many professionals refer to this type of platform for remote assistance as "VNC".

Benefits of Remote Control Desktop Software

There are a number of benefits associated with remote control desktop software. The following list depicts some of the many benefits that you may experience while working with this highly innovative technology:

1. One of the first benefits of this type of software is that it saves many businesses millions of dollars annually when it comes to internet technology personnel. When a company uses remote computing technology, any computer that is considered to be on that particular network can access the software that is being used at a base location. In addition to this, having remote desktop applications reduces the need to hire additional IT professionals for the purpose and intent of maintaining systems globally. By using this technology, a trained professional can tap right into the troubled system and resolve the issues from virtually any area in the world.

2. The next benefit is that it reduces costs for businesses that once went "on site" in order to fix computers, servers, and similar problems. Now, troubleshooting and technical support can be achieved from absolutely anywhere in the world with a click of a button!

3. The interface that is generally used in a remote computing software is relatively simple. Many novice users have successfully used this type of software to find that they completely understand what needed to be done, and how to do it.

Conclusion

There are many computing tips and tricks being passed around that can make the Windows experience more effective. Remote computer technology is certainly becoming more popular since more and more players enter this market. This has lead to remote computing technology becoming available and affordable even for the hobby computer enthusiast.

New remote computing solutions are popping up everywhere and many companies are competing in this space. This has lead to some very affordable remote computing solutions that even the home computer user can benefit from.

Cloud computing deals any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities. Cloud computing technology provides on-the-fly, point-and-click customization and report propagation for business users, so IT doesn't spend half its time making minor changes and running reports.

Cloud computing technology is tripping a huge change in application development circles. As a metaphor for the Cyberspaces, "the cloud" is a everyday cliche, but when combined with "computing," the meaning gets large and furrier. Today, for the most part, IT must jade into cloud-based services individually, but cloud figuring aggregators and integrators are already emerging. One potential security implication of cloud computing is that if you have individual data in that cloud, you are sharing hardware/networks with potential competitors in rather close propinquity, which is why for some folks building "clouds" they look to be for the most part just virtualization-heavy internal deployments. Cloud-based tools can be up and working in a few days, which is silent of with sanctioned business software.

Increasingly, IT squads are turning to cloud computation technology to minimize the time spent on lower-value natural actions and allow IT to focus on essential activities with greater impact on the business.

The cloud computing infrastructure not only provides deep customization and application configuration, it preserves all those customizations even during upgrades. By their very nature, cloud figuring technology is much better and quicker to incorporate with your other enterprise applications (both sanctioned software package and cloud computation infrastructure-based), whether third-party or homegrown.

By eliminating the problems of traditional application development, cloud computing technology releases you to focus on developing business applications that deliver true value to your business (or your customers).

The term cloud computing technology is one that gets mentioned a lot in today's business world but is it a technology that is suited to your business and one that you should employ? Cloud computing can be hard to quantify if you are new to the concept and it can be a struggle to get your head around what the term really means. In basic terms cloud computing means that all your computer power is managed through an imaginary space called "the cloud" and that all users within a company have access to this cloud. Through "the cloud" users will be able to access the company's software, applications and data at a shared location. What this means is that a company no longer requires physical storage as the cloud ensures that multiple users can access what they require in a secure open environment.

There are many reasons why companies should look to cloud computing technology and five main reasons which illustrate why you should be considering the technology are as follows.

Firstly, there is the cost saving potential of the technology. Employing cloud computing technology will ensure that computer hardware costs are reduced within an organisation. The more software, applications and data used within a company mean more resources being used. By using a cloud platform you can achieve better economies of scale as you can access a cloud provider's infrastructure which has already been developed for such economies. Also it is like a utility as you only pay for what you use, therefore your company no longer has to buy physical IT assets and make large capital investments.

Secondly, cloud computing gives your company flexibility as it allows your data to be accessed from anywhere and through different devices such as a mobile phone. This allows your company to be flexible as employees can connect to the cloud from anywhere and have access to the same features as if they were in the office.

Thirdly, cloud technology ensures that you have a central and reactive infrastructure. It ensures that data is located in a centralised location ensuring an impressive up-time level that with physical onsite technology is hard to achieve.

Fourthly, the security of the technology is renowned for being of a better standard than the network security measures that companies would have employed in the past. If your company depends on the security of your data and applications then cloud computing will ensure reliability.

Finally, by employing the right cloud computing technology and the right provider management becomes easy for your company. Cloud hosting providers will ensure there is no down-time (many through rigid and competitive SLA's to give your company peace of mind) and ensure that your physical data is organised and secure.

As you can see employing this technology has many advantages. The main advantages are the cost savings, the security and the ability to put the management of the cloud into a providers hands to manage and ensure up-time and standardisation for your company. It is little wonder that companies are harnessing the power of cloud computing and it is only a matter of time before this technology becomes common practice.

If you are interested in cloud computing the next step will be to talk to some experts to ensure that your company is suitable to move to a cloud-based environment. It will be understandable that you will have lots of questions and will want to speak to a company with renowned industry knowledge. The Cloud Computing Centre is a company that can help as they have helped hundreds of companies move into the cloud and can provide you with a fully functional environment to evaluate and check that moving to the cloud is for you.

What is pervasive computing? It all started in 1991 when Mark Weiser envisioned the next generation computer that weaves themselves into their environment. The next generation computers make themselves invisible and intuitive to use. Computers disappear into the background. If you're a Star Trek fan, think of the computers in this science fiction series, and you'll get the idea.

The term coined by Weiser, ubiquitous computing, is now synonymous to pervasive computing.

Computers as they exist today do not integrate themselves into our environment. You're aware of the fact that you're using a computer. The PC sits on top of your desk. You carry a laptop or pocket PC around. You need to acquire certain skills in order to use them, e.g. if you want to use a spreadsheet, you have to learn to use it.

Weiser envisioned an environment where computers are integrated into the environment in such a way that users are not even aware of the computers, or that they're using one. The computers disappear and become unobtrusive.

To illustrate the point, Weiser and his colleagues invented 3 types of devices: a tab, a pad and a board. The devices have no individualized association in they way that you associate a PC or laptop to a particular user, e.g. you can grab a tab and use it without having to figure out how you're going to configure or personalize it to your needs. A tab is a handheld device and can be easily carried around. You can use it to access your email, chat, or to pop up a reminder for you to ask a colleague to confirm next week's seminar if you run into him in the hallway. You'd have dozens of this in your environment.

A pad is kind of a digital version of a paper. You can spread it on your desk in the same way you spread papers on your desk.

The digital board replaces today's whiteboard. When a group of people gather in a room, the system detects that they belong to a project group and automatically downloads the previous discussion points on the board. You can write on the board using a digital pen while sitting a few meters away from it - just point and write.

Pervasive computing integrates computers and a smart environment, and blends them into the background. This technology is changing the way we work, live, and interact with each other.

Let's look at a few more examples of applications of this technology.

Cowboys on horsebacks herding cattle might one day become a feature of a bygone era as the introduction of virtual fences allows farmers to herd their cattle from the comfort of their homes. The virtual fence is downloaded to the cows by transmitting GPS coordinates to head-collars worn by the cows. The dynamic virtual fences are moved along desired trajectories. The collars are equipped with a Wi-Fi networking card, a Zaurus PDA, an eTrex GPS unit and a loudspeaker that transmits occurring sounds (for example, roaring tigers, barking dogs) when a cow strays from the intended path. This multi-disciplinary project, the brain child of a biologist, is made possible in collaboration with computer scientists.

Sensor technology can potentially play an important role in search and rescue operations by first responders, i.e. emergency personnel, such as firemen, paramedic, and police, who arrive at the scene immediately after an event (e.g. a fire, an earthquake, a building collapse) occurs.

Firemen wear tags to allow easy tracking of their movement in order to coordinate search and rescue operations more effectively. The firemen can be informed if a particular section of a building is found to be unstable and is about to collapse, and is directed to evacuate it immediately. A wireless vital sign monitor is attached to victims found trapped so that their condition can be monitored in order to ensure that they receive the appropriate medical attention as soon as they are rescued.

This non-invasive sensor monitors vital signs such as heart rate, oxygen saturation and serum chemistry measurements. The vital sign monitor helps the paramedic team determine which victims are in more critical conditions so that they can prioritize medical attention to more severely injured victims. The application and architecture required to support this emergency response application is being developed under the CodeBlue project at Harvard University, USA.

Wireless technology is also used in healthcare. The Arrhythmia Monitoring System (AMS) is a medical telemetry (telemedicine) system that makes use of wireless technology to monitor patients suffering from arrhythmia. Among the complications that arise from arrhythmia are the loss of regular heartbeat and subsequent loss of function, and rapid heartbeats.

AMS provides a means for healthcare professionals to continuously monitor a patient's electrical cardiac rhythms remotely even though the patient is not at the hospital. This technology allows patients to be in the comfort of their homes without jeopardizing their health. It is also useful for monitoring the heart functions of astronauts who are more susceptible to cardiac dysrhythmias when in space.

The examples illustrate the use of the technology in very different areas. There is no limit to the type of applications made possible by this technology. In the not too distant future, we will see this technology providing increased security, convenience, and ease of information access in our home and workplace.

Business application software has always been known to provide critical data whenever you need it. This is why it is so popular, particularly among large businesses, because it is able to help the managers run the business smoothly. From accounting and inventory systems, relational database management systems, sales projections to enterprise resource planning, these business applications have always proved their worth in day to day operations. This is why most large businesses attribute a huge part of their success to their IT infrastructure running the different business application software.

What about the small and medium sized businesses who do not have enough funds to invest in this kind of infrastructure? Well, some of them just rely on their small scale network with a host of freebie software, maybe one or two software applications that they bought off some computer store which they found out later is different from what they are used to. However, most of them just shake their heads in resignation, looking at the stars and wishing for something to take them out of this mess.

If you are one of these small or medium sized business owners, you may want to stop looking at the sky otherwise you would be counting neck pains as one of your present problems. It might be a good idea instead to look up some information about cloud computing because this reinvented technology may just provide the answers to your pressing business application software needs.

Cloud computing makes a plethora of the best business application software available, delivered as web based applications, to small and medium sized businesses like the one you have at a very low monthly subscription cost. There are a lot of cloud computing providers that offer software as a service to businesses who do not have adequate resources to invest in a really good IT infrastructure.

These providers maintain state of the art network servers, workstations, fast and reliable network connection, redundant backup systems, stable power source with uninterruptible power systems, and the best part of all these is that they have a team of experts, gurus, and geeks, working around the clock to provide your business excellent continuous service.

So who can benefit from cloud computing technology? You and millions of other owners of small or medium sized businesses who always wanted to have these state of the art business applications. You will no longer be browbeaten by large companies who maintain their own data centers because you now have the opportunity to access an even larger data center for your business application software needs.
