SHIPPING CONTAINERS REVOLUTIONIZED the way freight is moved around the world. By making it possible to pack all manner of cargo in a uniform way, shipping companies save money and streamline the process of loading and unloading goods. But it only worked because the size and shape of shipping containers are standardized, ensuring smooth transitions the trains hauling containers across the country to the boats designed to carry the containers across the ocean.
Software containers are poised to do the same thing for the web that shipping containers did for logistics. They make it far easier to move applications from the individual laptops and workstations where they are coded to the vast clusters of computers that serve those applications to customers. Now, a who’s who of tech companies, including Amazon, Google and Microsoft, have formed a new organization called the Open Container Project to create an open source standard for software containers.

A couple of years ago (almost to the day) Forbes coveredthe suggestion that PayPal was going to drop VMwarefrom its infrastructure in favor of OpenStack. The article actually impacted upon VMware’s VMW +0.51% share price for a time and it only surfaced later that PayPal was only making an initial foray into OpenStack. VMware breathed a sigh of relief.

Do you know that your public cloud provider used standard hyperviseor from xen (Linode), hyper-v(Azure), or vmware solutions.
Can you tell how secure is their setup? No. Because you have no control of the internal infrastructure of these cloud service providers.
CVE-2012-1666 – allows local users to gain privileges via a Trojan horse tpfc.dll file in the current working directory.
Look at Google Reader or more recent iGoogle. Service provider decided to serve you or not. If you based on one particular technology or feature – then you are in risk. That service or feature might be shut down at any time because provider is not interested in such service anymore. As well as the API. Interface to cloud services might vary and you need to control these changes to keep your business running.
So. Please combine all risks and benefits and decide if you really need public cloud. If so – please backup.
The IT industry discourages users from considering these distinctions. That’s what the buzzword “cloud computing” is for. This term is so nebulous that it could refer to almost any use of the Internet. It includes SaaS and it includes nearly everything else. The term only lends itself to uselessly broad statements.
The real meaning of “cloud computing” is to suggest a devil-may-care approach towards your computing. It says, “Don’t ask questions, just trust every business without hesitation. Don’t worry about who controls your computing or who holds your data. Don’t check for a hook hidden inside our service before you swallow it.” In other words, “Think like a sucker.” I prefer to avoid the term.
DESKTOP AS A SERVICE. YOUR CLOUD IS GETTING MORE HELPFUL.
Virtual desktop infrastructure (VDI) Users have they own application spaces. Thin clients where applications might run ether locally or on server, shared filesystem, own graphics and audio, ability to connect local devices such as USB stick etc.
Remote desktop Service (RDS) is pretty much like having screen of the “big brother” server somewhere. All users logged into one server. It is usually more complicated to setup, limited connections and low performance however it might save you some dollars on software licenses.
There is even more modern way in desktop virtualisation. Bring Your Own Device (BYOD).
One more interesting option is to share running applications. For example you can run Photoshop on virtul machine and export an aplication window to the network. Then authorised users will login and use it one after another.
We are working to develop a strategy to combine all options as above in one cost effective DaaS solution.
