It's Not About Apple vs. Microsoft, Or Apple vs. Google. It's About Freedom.

30 Aug 2011

We are learning once again that what people want most is to be free


John Quincy Adams (sixth President of the US) said: "Who but shall learn that freedom is the prize… and on the oppressor's head to break the chain." Glorious change. Monumental change. Empowerment and Freedom. I submit humbly but with absolute conviction to all of you that we are in the midst of revolution in personal computing - the extent of which we will only fully comprehend once it's over, and established vendors and IT leaders alike are scattered on the side of the road.

It's not about Microsoft vs. Apple or Google vs. Apple. It's about freedom. Freedom from control. Freedom from establishments. Freedom of identity. Freedom from IT departments too understaffed and ill-equipped to help. Freedom from layers of management agents and miscellaneous junk that sap minutes to hours of productive time from our lives every day. The price of compliance and security you say? Hogwash.

End user experience is at an all-time low


The end user experience has deteriorated to the point that we sit and wait while the hourglass spins, as IT's remote bots take inventory, or install software updates while we're frantically trying to get our slides together for a customer meeting. The mindless bots scan for threats and lock the cursor while we're trying to write an e-mail, and we get embarrassing pop-up reminders while we're presenting to rooms full of people to make sure we know to update Adobe Acrobat. We're as mad as hell, and we're not going to take it any more! Who gave someone the right to assume that what their tool needs to do at any given moment is more important than the work we have to get done?

High performers are being hanged for taking matters into their own hands


Our workspaces don't belong to us any more, so more and more of us are choosing to go it alone and risk the wrath. One of the brightest people I know was fired from a company recently because his IT department determined he was violating security policy by using his personal computer in the office rather than the one IT provided. The one IT provided was too underpowered for his job, so he had purchased one (with his own money) that would work. In any rational situation, he might have been rewarded for his commitment. Instead, he was dismissed, and his former employer's top competitor snapped him up in less than two weeks -- this guy had closed $3m in business last year. It's lunacy! I go back to John Quincy Adams again: "To believe all men honest would be folly. To believe none so is something worse." Perhaps this thinking has something to offer us.

It doesn't have to be like this


So what do we as I&O professionals do? We can start by embracing the idea that less is more, and that the best way to shape behavior is to create value where you want people to go. As you are developing your support plans for virtual desktops and mobile devices, and you think "how will we control…", stop yourself. Think instead about how you will make it easier for people to adopt these devices without breaking the regulations your business is sworn to uphold. The client virtualization mobile apps from Citrix and VMware are a great help here, and the LogMeIn client for remote control of any desktop is the best I've seen. Think in terms of automated configuration for e-mail on iOS and Android to ease the burden on the user and the service desk. Make sure both e-mail addresses AND phone numbers are in Exchange so that everyone in the firm using a mobile device can call any other employee.

New technologies must be allowed to unleash new levels of productivity and value


For virtual desktops, try to figure out how to manage them without the same layers of agents you used on the physical desktops. I saw some interesting technology from a company called Ziften this week that looks promising because it controls how much CPU, memory and I/O extraneous "stuff" can consume. Think about offering service catalogs full of pre-configured virtual desktops that people can request and use for specific purposes. Imagine a graphics design workstation offering with all the trimmings, or an engineering workstation designed by the finest engineers in your organization. These kinds of ideas will create value that really leverages what these technologies can offer your business, and people will go where they see value for them.

What do you think? What are some great ways to strike a better balance between information security and usability? How can we offer people freedom of choice in personal computing without spending more on management and support? If you are doing this today, what tools are indispensible to you?

System management capabilities to focus on for ramping up virtualization in 2011

08 Dec 2010

When thinking about their 2011 IT initiatives, many firms I've spoken with are continuing to build out their virtual server environments. My colleague Gene Leganza has written an excellent report entitled The Top 15 Technology Trends EAs Should Watch that includes system management as a driver of continued virtualization.

In addition, it is now becoming apparent that public and private cloud computing architectures are becoming more and more intertwined due to the intersection of virtualization platforms and management tools. From a technology standpoint, I believe that management is one of the key enablers of virtualized and cloud infrastructure. Therefore, as you're making your 2011 plans and virtualization or cloud computing inevitably pops up, think about how the following system management capabilities will influence your strategy:

1.    Integration of public and private cloud management. Management tools for managing virtualization platforms will integrate with cloud services. In the beginning it will be about monitoring or provisioning. Later on, your system management infrastructure will orchestrate the movement between internal and external resource pools.

2.    Capacity planning and optimization. Most firms we speak with don't take a very mathematical approach to determining how much physical capacity is required to power all their virtualized systems. This leads to the same sort of overprovisioning that created all this waste in the first place. That's one big reason the average ratio of virtual to physical machines at many firms is down around 10 to 1. You'll never come close to cloud computing levels of efficiency at that rate. Capacity planning and optimization tools will calculate just how much public or private infrastructure you need to run your apps and how best to arrange the VMs for maximum efficiency.

3.    Streamlining ongoing management of servers. One of the biggest barriers to scaling up virtualization is the ongoing management of virtual machines. Why is this important? If you manage a server the same way you always have, then the ongoing costs of maintaining a virtualized server will be the same as they always have been. In addition to standardizing images and other process-related things, you should be automating configuration management. Also, think about whether you can move to an image-based approach as we describe in this report on the future of configuration management.

4.    Real-time automation of workload management. As server hardware becomes more powerful (for example, the newest blades with 1 TB of memory), we'll naturally want to increase our VM density to achieve a lower cost per VM. The result is that individual servers will be increasingly critical to application availability. This translates to a need for real-time automation and performance management that can instantly respond to performance issues or failures by moving application services to another system. Many firms use live migration features in their server virtualization platform -- but these must be linked with more-accurate indicators of end user experience, like synthetic transactions from an application performance management tool.

5.    Management of virtualized I/O. What do the the unified or converged infrastructure from HP, VCE (VMware/Cisco/EMC), IBM, and Egenera have in common? Virtualized I/O -- usually in the form of 10 Gb converged Ethernet. Aside from benefits like reducing cabling and switch ports, I think the most interesting aspect of virtualized I/O is the ability of a physical server's personality to be moved to any other server in the data center. In addition to the underlying network technology, the thing that makes this possible is integrated management of the server and data center fabric. In most cases, this won't be a stand-alone product that you acquire (though you can build your own solution from InfiniBand and PCI Express products on the market). This capability will most likely be an integrated part of whatever server and network environments you select, but now is the time to begin planning how you'll tie it in with the rest of your system management environment.
