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.
The marketshare data for external disk systems has been released by IDC for 4Q09. Overall, the market dropped 0.7 percent, comparing 4Q09 versus 4Q08. While EMC was quick to remind everyone that they were able to [maintain their #1 position] in the storage subset of "external disk systems", with the same 23.7 percent marketshare they had back in 4Q08 and revenues that were essentially flat, the real story concerns the shifts in the marketplace for the other major players. IBM grew revenue 9 percent, putting it nearly 5 points of marketshare ahead of HP. HP revenues dropped 7 percent, moving it further behind. Not mentioned in the [IBM Press Release] were NetApp and Dell, neck and neck for fourth place, with NetApp gaining 16.8 percent in revenues, while Dell dropped 13.5 percent. Both NetApp and Dell now have about 8 percent marketshare each. These top five storage vendors represent nearly 70 percent of the marketshare.
Given that HP is IBM's number one competitor, not just in storage but all things IT, this was a major win. Bob Evans from InformationWeek interviews my fifth-line manager, IBM executive Rod Adkins [IBM Claims Hardware Supremacy] where he shares his views and opinions about HP, Oracle-Sun, Cisco and Dell. I'll add my two cents on what's going on:

This week I got a comment on my blog post [IBM Announces another SSD Disk offering!]. The exchange involved Solid State Disk storage inside the BladeCenter and System x server line. Sandeep offered his amazing performance results, but we have no way to get in contact with him. So, for those interested, I have posted on SlideShare.net a quick five-chart presentation on recent tests with various SSD offerings on the eX5 product line here:
Sandeep, if you see this, we would also be interested in seeing your results as well.

Well, it's Tuesday again, and that means IBM announcements! Right on the heels of our big storage launch on February 9, today IBM announced some exciting options for its modular disk systems. Let's take a look:
It also appears that the reports and rumors of the death of the DS6800 are premature. Don't believe misleading statements from competitors, such as those found written by fellow blogger BarryB (EMC), aka "the Storage Anarchist", in his latest post [Bring Out Your Dead] showing a cute little tombstone with "Feb 2010" on the bottom. Actually, if he had bothered to read IBM's [Announcement Letter], he would have realized that IBM plans to continue to sell these until June. Of course, IBM will continue to support both new and existing DS6800 customers for many years to come.
Technically, BarryB does not make any factually incorrect statements for me to correct on his blog. The idea that a product is "dead" is, of course, just opinion, and competitors poke fun at each others' announcements every day. One could argue that the EMC V-Max was "dead" after the ITG whitepaper [Cost/Benefit Case for IBM XIV Storage System - Comparing Costs for IBM XIV and EMC V-Max Systems] demonstrated that the IBM XIV cost 63 percent less than a comparable EMC V-Max over the life of three years total cost of ownership (TCO) back in July 2009. The comparison was made with data from clients in a variety of industries including manufacturing, health care, life sciences, telecommunications, financial services, and the public sector. This could explain why so many EMC customers are buying or investigating the IBM XIV and the rest of the IBM storage portfolio.

A long time ago, perhaps in the early 1990s, I was an architect on the component known today as DFSMShsm on z/OS mainframe operationg system. One of my job responsibilities was to attend the biannual [SHARE conference to listen to the requirements of the attendees on what they would like added or changed to the DFSMS, and ask enough questions so that I can accurately present the reasoning to the rest of the architects and software designers on my team. One person requested that the DFSMShsm RELEASE HARDCOPY should release "all" the hardcopy. This command sends all the activity logs to the designated SYSOUT printer. I asked what he meant by "all", and the entire audience of 120 some attendees nearly fell on the floor laughing. He complained that some clever programmer wrote code to test if the activity log contained only "Starting" and "Ending" message, but no error messages, and skip those from being sent to SYSOUT. I explained that this was done to save paper, good for the environment, and so on. Again, howls of laughter. Most customers reroute the SYSOUT from DFSMS from a physical printer to a logical one that saves the logs as data sets, with date and time stamps, so having any "skipped" leaves gaps in the sequence. The client wanted a complete set of data sets for his records. Fair enough.
When I returned to Tucson, I presented the list of requests, and the immediate reaction when I presented the one above was, "What did he mean by ALL? Doesn't it release ALL of the logs already?" I then had to recap our entire dialogue, and then it all made sense to the rest of the team. At the following SHARE conference six months later, I was presented with my own official "All" tee-shirt that listed, and I am not kidding, some 33 definitions for the word "all", in small font covering the front of the shirt.
I am reminded of this story because of the challenges explaining complicated IT concepts using the English language which is so full of overloaded words that have multiple meanings. Take for example the word "protect". What does it mean when a client asks for a solution or system to "protect my data" or "protect my information". Let's take a look at three different meanings:
If these three methods of protection sound familiar, I mentioned them in my post about [Pulse conference, Data Protection Strategies] back in May 2008.
