Understanding iCloud

9 Replies victor

The latest release in the cloud computing world, and the replacement for Apple’s old MobileMe service is Apple iCloud. The new software is designed to work seamlessly between various apple hardware such as iPods, Apple laptops and desktops, and the iPad. There are several applications available with the iCloud software, ranging from ‘Find my Device’, which allows an internet connected device such as the iPhone to be remotely tracked, to Photo Stream, which makes ‘streamed’ photos available on any connected device.

The first, Find My Device, was initially a MobileMe application, which has been migrated to the iCloud software package. Using the service, a user can view the rough location of their device over-layed on a scalable map of the area, as well as a circle indicating the margin of error on the tracking. Along with remote tracking, the program also allows the user to change the password, display a message on the device, or play a sound (even if it is set to silent). A final feature of the program makes use of the cloud storage technology and allows the user to temporarily delete the contents of the device, storing them to the cloud server until told to return to their original location.

Computing from the cloud

Not quite cloud computing!

Photo Stream directly utilizes the cloud storage technology to share pictures between devices. When a picture is taken from an iphone with Photo Stream enabled, the picture will automatically be uploaded to the cloud server, where it will be available to any of the user’s other Photo Stream enabled machines. According to Apple, the service will soon be integrated with their Apple TV box, which would allow users to view any pictures in icloud on TVs connected to Apple TV.

While only currently available in the US, iTunes Match is one of the most popular uses for the virtual computing abilities of the iCloud software. iTunes Match allows users to ‘scan’ their music in any compatible device (even if the music is not purchased from iTunes), and upload it to the iCloud virtual servers, ready to be downloaded to any of the user’s other Apple products in a DRM free format.

‘Back To My Mac’ and iOS Backup are two more erstwhile MobileMe program migrated to the iCloud package. The first is essentially a remote access program, allowing the user to remotely log into any device with the same Apple ID and the program active. The second is a backup program, which allows the user to back up the data and settings on their device to the virtual servers, and restore the device or access the data remotely as needed.

While the iCloud software is very slim as far as system resources, it requires a fairly current OS to run properly. Creating an account requires iOS 5 or later, or for desktops, OSX Lion. For PCs, Windows Vista or later is required to properly sync. iCloud can also sync to Outlook 7 or later for calendars and contact info.

The cost of the iCloud software varies with the amount of services the user chooses to sign up for. Data storage starts at 5 gigabytes free, and added storage can be purchased in increments of ten gigabytes, for $20 per ten gigabytes per year. At the moment, the maximum storage amount available is 50 gigabytes, however Apple has said it is possible for that to go up in the future. Apart from storage costs, the iTunes Match service is a yearly fee of $25.

With the iCloud software, Apple has taken full advantage of the evolving cloud storage technology to bring a wide variety of programs to Apple users, and an increased connectivity between Apple hardware.

Why Is Cloud Computing So Important?

Cloud computing has a lot of hype surrounding it. More than a few observers have wondered what is so important about this new internet phenomenon. The truth is cloud computing is leading to a rethinking of the internet’s capability. Cloud computing promises to completely delocalise computing power and technology. Users will be able to access and manipulate files, images, videos and other data remotely. Cloud computing promises the ability to keep networks and mobile devices synchronised at all times.

Infrastructure

A bank of sophisticated computers host operating systems and data for hundreds, if not thousands, of customers. internet search engine giant Google pioneered the use of data centers to store clients’ personal data safely. The same principle is being extended to cloud computing. Huge data centers will act as remote desktop computers. These centers will be able to store every file a user would need. All the user needs is a counterpart machine that can be as small as a conventional laptop with much less weight. These so-called “netbooks” serve only to connect the user to the internet so he can access his files.

A cloud computing network

An example of how cloud computing works – every device synchronises with the cloud, meaning that your data can be accessed anywhere!

A single data center can offer multiple services and applications. Theoretically, a cloud computing system could perform almost any function or task the user desires. In a typical system, each application will have its own dedicated server combined with multiple iterations to create redundancy and prevent sudden malfunctions. The whole center is managed by a central server that constantly monitors the traffic and load volumes. Balancing the differences between machines, it seeks to maintain the harmony of the system and prevent crashes.

Business Advantages

The advent of cloud computing is actually forcing businesses to change their strategies. Previously, hiring a new employee meant providing him with a desk, computer equipment and various other hardware or software. Cloud computing allows them to reduce these capital expenditures significantly. Now all an employee needs is a computer with an internet connection to access his work data. Desks and office equipment may still be necessary, but the investment in computer hardware can be outsourced to cloud computing companies.

The hardware and software demands on the business’s side decrease dramatically. Labor costs per individual employees go down, enabling a company to hire more workers. Productivity increases, raising the efficiency and profits of the business.

Concerns

The primary reason why cloud computing is getting so much attention is its effect on business strategies. The sheer cost pressure alone is forcing industry after industry to adapt to the new reality. The advantages notwithstanding, several valid concerns about cloud computing exist, namely having to do with privacy and security.

Business owners and executives may hesitate to turn over their sensitive data to a third-party system with good reason. Losing access to their own data or having it compromised is unacceptable in a ruthlessly competitive private sector. One major argument against this fear is the fact that cloud computing companies survive based on their reputations. This gives them a huge incentive not to lose their clients data or compromise accessibility. Despite the power of this incentive, regulations may still be required to ensure safety.

As for privacy, the obvious concern is the connection between the user’s computer and the cloud system. Privacy could easily be compromised by unscrupulous individuals who could access personal information like credit card numbers. A solution to this problem is to use authentication and encryption like regular secure connections.

These practical concerns are somewhat overshadowed by a number of philosophical and legal questions. For instance, who owns the data stored by the cloud computing system? While it is held in the client’s name, a case could conceivably be made that the cloud computing system is the actual owner and therefore has a right to it. These technicalities are still under debate, and no resolution has yet been achieved.

Conclusion

Cloud computing holds great promise for upending things as they are currently done in the business world. The practical effects on information technology jobs will likely be profound. These and other challenges must be met because cloud computing will continue to change the nature of the internet.

Windows 8 is on the way!

I have recently upgraded to Windows 7, which is why I kind of wasn’t that pleased when Microsoft announced (early last week) that it was getting set to launch its next operating system, Windows 8, some time next year – probably around April.


At the Build developers’ conference in California, Microsoft unveiled the new operating system, (no doubt still in early beta stages) and gave us a sneak peak at to what is in store in the next version of Windows.

They stated that the core foundation of Windows 8 was Windows 7, but better! To quote Steven Sinofsky exactly, he said:

…everything that was great about windows 7, well we took that and we made it even better in Windowws 8!

Despite saying this, this version of Windows OS looks like it has had a dramatic overall.

Windows is currently under more pressure than ever before in its long, domineering history. In the past the cheap, affordable and compatible OS, always used to be Microsoft’s Windows. Now however Apple are putting increasing pressure on Windows, along with Google’s new attempt to bring down the giant of Windows in the form of Chrome OS.

Hence why Windows 8 seems to be dramatically different to all previous versions of Windows.

So what is going to be different? Well for starters, for the first time ever, a Windows OS will be compatible with low power ARM-designed processors.

Also, from the glimpses and comments that Microsoft have currently given us/made, it looks like Microsoft are attempting to make Windows a more ‘family friendly’ operating system, in that it’s more of a media based OS. This is probably done to try and steer away from the classical view of Windows in that it is an operating system designed primarily for spreadsheets, documents and other work/business related tasks.

Windows 8 Start Screen

A glimpse at the probably new start screen design for Windows 8

In addition to this, Windows 8 will support touchscreen devices, possible Microsoft’s way of saying “get ready for Windows Tablet guys!” who knows.

Microsoft knows that it has to pull something pretty special out of the bag this time, or it could seriously loose its foot in the computing market, not only due to the increased competition, but also because users are slowly moving away from desktops and laptops, and towards smart phones and tablets.

That’s pretty much all the information I have at the moment, however no doubt we will have loads of updates on Technology Bloggers for you, as soon as we find out more about this new OS 🙂

What do you think and hope for with Windows 8? Do you speculate that it will be another Vista – i.e. slow and laggy, incompatible, riddle with bugs, and hated by many tech gurus, or will it be like Vista to 7, a breath of fresh air?
