Last week, I presented "An Introduction to Cloud Computing" for two hours to the local Institute of Management Accountants [IMA] for their Continuing Professional Education [CPE]. Since I present IBM's leadership in Cloud Storage offerings, I have had to become an expert in Cloud Computing overall. The audience was a mix of bookkeepers, accountants, auditors, comptrollers, CPAs, and accounting teachers.
I have posted my charts on Slideshare.Net:
Here is a sample of the questions I took during and after my presentation:If I need to shut down host machine, I lose all my virtual machines as well?
No, it is possible to seemlessly move virtual machines from one host to another. If you need to shut down a host machine, move all the VMs to other hosts, then you can shut down the empty host without impacting business.Does the SaaS provider have to build their own app, can they not buy an app and then rent it out?
Yes, but they won't have competitive differentiation, and the software development they buy from will want a big cut of the action. SaaS developers that build their own applications can keep more of the profits for themselves.How do backups work in cloud computing? Do I have to contact someone at the cloud computing company to find the backup tape?
Large datacenters often keep the most recent backups on disk, and older versions on tape in automated tape libraries that can fetch your backup in less than 2 minutes. Because of this, there is no need to talk to anyone, you can schedule or invoke your own backups, and often perform the recovery yourself using self-service tools.Last month, my sister tried to rent a car during the week the Tucson Gem Show, but they were out of cars she wanted to drive. Could this happen with Cloud Computing?
Not likely. With rental cars, the cars have to be physically in Tucson to rent them. Rental companies could have brought cars down from Phoenix to satisfy demand. With Cloud Computing, it is all accessible over the global network, you are not limited to the cloud providers nearest you.Is there a reason why Amazon Web Services (AWS) charges more for a Windows image than a Linux image?
Yes, Amazon and Microsoft have a patent cross-licensing agreement where Amazon pays Microsoft for the priveledge of offering Windows-based images on their EC2 cloud infrastructure. It just makes business sense to pass those costs onto the consumer. Linux is a free open source operating system, and is often the better choice.So if we rent a machine from Amazon, they send it to my accounting office? What exactly am I getting for 12 cents per hour?
No. The computer remains in their datacenter. You get a virtual machine that runs 1.2Ghz Intel processor, with 1700MB of RAM, and 160GB of hard disk space, with Windows operating system running on it, comparable to a machine you can get at the local BestBuy, but instead of it running in the next room, it is running in a datacenter somewhere else in the United States with electricity and air conditioning. You access it remotely from your desktop or laptop PC.Why would I ever rent more than one computer?
It depends on your workload. For example, Derek Gottfrid at the New York Times needed to convert 11 million articles from TIFF format to PDF format so that he could put them up on the web. This would have taken him months using a single computer, so he rented 100 computers and got the entire stack converted in 24 hours, for a cost of about $240. See the articles [Self-Service, Prorated, Super Computing] and [TimesMachine] for details.What about throughput? Won't I need to run cables from my accounting office to this cloud computing data center?
You will need connectivity, most likely from connections provided by your local telephone or cable company, or through the Internet. Certainly, there can be cases where direct privately-owned fiber optic cables, known as "dark fiber", can directly connect consumers to local Cloud service providers, for added security.What about medical records? Will Cloud Computing help the Healthcare industry?
Yes, hospitals are finding that digitizing their records greatly reduces costs. IBM offers the Grid Medical Archive Solution [GMAS] as a private cloud storage solution to store X-ray images and other electronic medical records on disk and tape, and these records can be accessed from multiple hospitals and clinics, wherever the doctor or patient happens to be.The advantage of personal computers was individualization, I could put on my own choices of software, and customize my own settings, won't we lose this with Cloud Computing?
Yes, customized software and settings cost companies millions of dollars with help desk calls. Cloud Computing attempts to provide some standardization, reducing the amount of effort to support IT operations.Won't putting all the computers into a big datacenter make them more vulnerable to hackers?
Security is a well-known concern, but this is being addressed with encryption, access control lists, multi-tenancy isolation, and VPN connections.My daughter has a BlackBerry or iPod or something, and when we mentioned that someone in Phoenix wore a monkey suit to avoid photo-radar speed cameras, she was able to pull up a picture on her little hand-held thing, is this the future?
Yes, mobile phones and other hand-held devices now have internet access to take advantage of Cloud Computing services. People will be able to access the information they need from wherever they happen to be. (You can see the picture here: [Man Dons Mask for Speed-Camera Photos])
IBM offers a variety of Cloud Computing services, as well as customized solutions and integrated systems that can be deployed on-premises behind your corporate firewall. To learn more, go to [ibm.com/cloud].
The second speaker was local celebrity Dan Ryan presenting the financials for the upcoming [Rosemont Copper] mining operations. Copper is needed for emerging markets, such as hybrid vehicles and wind turbines. Copper is a major industry in Arizona.
It seems everyone is talking about stacks, appliances and clouds.
On StorageBod, fellow blogger Martin Glassborow has a post titled [Pancakes!] He feels that everyone from Hitachi to Oracle is turning into the IT equivalent of the International House of Pancakes [IHOP] offering integrated stacks of software, servers and storage.
Cisco introduced its "Unified Computing System" about a year ago, [reinventing the datacenter with an all-Ethernet approach]. Cisco does not offer its own hypervisor software nor storage, so there are two choices. First, Cisco has entered a joint venture, called Acadia, with VMware and EMC, to form the Virtual Computing Environment (VCE) coalition. The resulting stack was named Vblock, which one blogger had hyphenated as Vb-lock to raise awareness to the proprietary vendor lock-in nature of this stack. Second, Cisco, VMware and NetApp had a similar set of [Barney press releases] to announce a viable storage alternative to those not married to EMC.
On StorageMojo, fellow blogger Robin Harris presents [A deep dive into Cisco’s UCS]. Here is an excerpt:
"Only when it makes sense. Oracle/Sun has the better argument: when you know exactly what you want from your database, we’ll sell you an integrated appliance that will do exactly that. And it’s fine if you roll your own. But those are industry-wide issues. There are UCS/VCE specific issue as well:Appliances and Linux]. Here is an excerpt:
If your company was a restaurant, how many employees would you have on hand to produce your own electricity from gas generators, pump your own water from a well, and assemble your own toasters and blenders from wires and motors? I think this is why companies are re-thinking the way they do their own IT.
Rather than business-as-usual, perhaps a mix of pre-configured appliances, consisting of software, server and storage stacked to meet a specific workload, connected to public cloud utility companies, might be the better approach. By 2013, some analysts feel that as many as 20 percent of companies might not even have a traditional IT datacenter anymore.
Fellow blogger David Salgado (Microsoft) rips into the IT industry for [marketing these "stacks" of components as "private clouds"]. Fellow blogger Mary-Jo Foley (Microsoft) asks ['Private cloud' = just another buzzword for on-premise datacenter?"] adds more attention to the confusion over the terms private and public cloud. Here's an excerpt that shows Microsoft's thinking in this area:
Finally, I saw this from fellow blogger, Barry Burke(EMC), aka the Storage Anarchist, titled [a walk through the clouds] which is really a two-part post.
The first part describes a possible future for EMC customers written by EMC employee David Meiri, envisioning a wonderful world with "No more Metas, Hypers, BIN Files...."
The vision is a pleasant one, and not far from reality. While EMC prefers to use the term "private cloud" to refer to both on-premises and off-
A good analogy for "private cloud" might be a corporate "intranet" that is accessible only within the company's firewall. This allowed internal websites where information to be disseminated to employees could be posted, using standard HTML and standard web browsers that are already deployed on most PCs and workstations. Web pages running on an intranet can easily be moved to an external-facing website without too much rework or trouble.
The second part has Barry claiming that EMC has made progress towards a "Virtual Storage Server" that might be announced at next month's EMC World conference.
When people hear "Storage Virtualization" most immediately think of the two market leaders, IBM SAN Volume Controller and Hitachi Data Systems (HDS) Universal Storage Platform (USP) products. Those with a tape bent might throw in IBM's TS7000 virtual tape libraries or Oracle/Sun's Virtual Storage Manager (VSM). And those focused on software-only solutions might recall Symantec's Veritas Volume Manager (VxVM), DataCore's SANsymphony, or FalconStor's IPStor products.
But what about EMC's failed attempt at storage virtualization, the Invista? After five years of failing to deliver value, EMC has so far only publicised ONE customer reference account, and I estimate that perhaps only a few dozen actual customers are still running on this platform. Compare that to IBM selling tens of thousands of SAN Volume Controllers, and HDS selling thousands of their various USP-V and USP-VM products, and you quickly realize that EMC has a lot of catching up to do. EMC's first delivered Invista about 18 months after IBM SAN Volume Controller, similar to their introduction of Atmos being 18 months after our Scale-Out File Services (SoFS) and their latest CLARiiON-based V-Max coming out 18 months after IBM's XIV storage system.
So what will EMC's Invista follow-on "Virtual Storage Server" product look like? No idea. It might be another five years before you actually hear about a customer using it. But why wait for EMC to get their act together?
IBM offers solutions TODAY that can make life as easy as envisioned here. IBM offers integrated systems sold as ready-to-use appliances, customized "stacks" that can be built to handle particular workloads, residing on-premises or hosted at an IBM facility, and public cloud "as-a-service" offerings on the IBM Cloud.

Continuing my coverage of the Data Center Conference 2009, held Dec 1-4 in Las Vegas, the title of this session refers to the mess of "management standards" for Cloud Computing.
The analyst quickly reviewed the concepts of IaaS (Amazon EC2, for example), PaaS (Microsoft Azure, for example), and SaaS (IBM LotusLive, for example). The problem is that each provider has developed their own set of APIs.
(One exception was [Eucalyptus], which adopts the Amazon EC2, S3 and EBS style of interfaces. Eucalyptus is an open-source infrastrcture that stands for "Elastic Utility Computing Architecture Linking Your Programs To Useful Systems". You can build your own private cloud using the new Cloud APIs included Ubuntu Linux 9.10 Karmic Koala termed Ubuntu Enterprise Cloud (UEC). See these instructions in InformationWeek article [Roll Your Own Ubuntu Private Cloud].)
The analyst went into specific Virtual Infrastructure (VI) and public cloud providers.
If you prefer a common management system independent of cloud provider, or perhaps across multiple cloud providers, you may want to consider one of the "Big 4" instead. These are the top four system management software vendors: IBM, HP, BMC Software, and Computer Associates (CA).
A survey of the audience found the number one challenge was "integration". How to integrate new cloud services into an existing traditional data center. Who will give you confidence to deliver not tools for remote management of external cloud services? Survey shows:
Some final thoughts offered by the analyst. First, nearly a third of all IT vendors disappear after two years, and the cloud will probably have similar, if not worse, track record. Traditional server, storage and network administrators should not consider Cloud technologies as a death knell for in-house on-premises IT. Companies should probably explore a mix of private and public cloud options.

Continuing my coverage of the Data Center 2010 conference, Monday I attended four keynote sessions.
That was just Monday morning, this is going to be an interesting week!
