Once, IT was a monopoly.

http://www.flickr.com/photos/theclevelandkid24/4251408727/Thursday, June 17, 2010

Today, it’s a free market. The line of business has tremendous choice in what it owns, runs, and uses.

http://www.flickr.com/photos/hyku/2039448524/Thursday, June 17, 2010

The boardroom loves this: instead of managing machines, they manage services.

http://www.flickr.com/photos/ukanda/4455286483/Thursday, June 17, 2010

But enterprise IT doesn’t like it much, because it forces them to compete, and puts them side-by-side with organizations that spend their entire day doing detailed usage and billing.

http://en.wikipedia.org/wiki/Adam_SmithThursday, June 17, 2010

It’s not all bad, though. There’s a lot to be learned from a transition from monopoly to a free market.

Two reasons.

Thursday, June 17, 2010

There were a couple of reasons IT was a monopoly for so long.

Second, they were complicated. It took a very strange sect of experts to understand them. AVIDAC, Argonne's first digital computer, began operation in January 1953. It was built by the Physics Division for $250,000. Pictured is pioneer Argonne computer scientist Jean F. Hall.

AVIDAC stands for "Argonne Version of the Institute's Digital Automatic Computer" and was based on the IAS architecture developed by John von Neumann.

http://www.flickr.com/photos/ebeam/3586287989/Thursday, June 17, 2010

This was also a result of scarcity. When computers and humans interact, they need to meet each other halfway. But it takes a lot of computing power to make something that’s easy to use;

A monopoly was once awarded for a big project beyond the scope of any one organization, but needed for the public good.

http://www.flickr.com/photos/athomeinscottsdale/2850893998/Thursday, June 17, 2010

Sometimes, nobody wants the monopoly—like building the roads.

Thursday, June 17, 2010

For the most part, governments have a monopoly on roadwork, because it’s something we need, but the benefits are hard to quantify or charge back for.

http://www.flickr.com/photos/leokoivulehto/2257818167/Thursday, June 17, 2010

(IT’s been handed many of these thankless tasks over the years, and the business has never complained.)

http://www.flickr.com/photos/crobj/4148482980/Thursday, June 17, 2010

The only time we can charge back for roads are when the resource is specific and billable: a toll highway, a bridge.

http://en.wikipedia.org/wiki/File:Bell_System_hires_1900_logo.PNG

Thursday, June 17, 2010

Sometimes, we form a company with a monopoly, or allow one to operate, in order to build something or allow an inventor to recoup investment. This is how we got the telephone system, or railways.

For much of its history, AT&T and its Bell System functioned as a legally sanctioned, regulated monopoly.

The US accepted this principle, initially in a 1913 agreement known as the Kingsbury Commitment.

Anti-trust suit filed in 1949 led in 1956 to a consent decree whereby AT&T agreed to restrict its activities to the regulated business of the national telephone system and government work.

Changes in telecommunications led to a U.S. government antitrust suit in 1974.

In 1982 when AT&T agreed to divest itself of the wholly owned Bell operating companies that provided local exchange service.

In 1984 Bell was dead. In its place was a new AT&T and seven regional Bell operating companies (collectively, the RBOCs.)

http://www.corp.att.com/history/history3.htmlThursday, June 17, 2010

When monopolies are created with a specific purpose, that’s good. But when they start to stagnate and restrict competition, we break them apart.

http://www.flickr.com/photos/ktylerconk/4096965228/Thursday, June 17, 2010

In fact, there’s a lot of antitrust regulation that prevents companies from controlling too much of something because they can stifle innovation and charge whatever they want. That’s one of the things the DOJ does.

First: Monopoly good.

Thursday, June 17, 2010

In other words, early on monopolies are good because they let us undertake hugely beneficial, but largely unbillable, tasks.

Then: Monopoly bad.

Thursday, June 17, 2010

Later, however, they’re bad because they reduce the level of creativity and experimentation.

It’s also not complicated. Everyone can use a computer. Because today, the computer is cheap and the human’s expensive we spend so much time on user interfaces, from GUIs to augmented reality to touchscreens to voice control to geopresence.

Three really big changes.

Thursday, June 17, 2010

We’ve had big changes since that time. The first was client-server computing: the idea that not everything lived in a mainframe, and some things worked well on the desktop. Software like Visicalc—the first spreadsheet—were useful for businesses, even those who couldn’t afford a mainframe.

http://en.wikipedia.org/wiki/File:NCSA_Mosaic.PNGThursday, June 17, 2010

A second big change was the Web. This browser-based model made computing accessible to the masses. As a result, it became part of society, and everyone knew how to work it. These days, you don’t have to teach a new hire how to use a web browser: they know what links do; what the back button is; and so on.

A third change is the move to mobility. This has been bigger overseas, where the mobile phone is the dominant way of accessing the Internet, but it’s still a shift to the always-connected, always-on lifestyles we lead today.

Now here come clouds

Cloud computing is an approach to computing that’s more flexible and lets organizations focus on their core business by insulating them from much of the underlying IT work.

http://www.flickr.com/photos/juniorvelo/3577399832/Thursday, June 17, 2010

At its most basic, it’s computing as a utility – pay for what you need, when you need it, rather than paying for it all up front.

The human-intensive component of IUP is computed by using completed period 1 interactions, instead of all TSO interactions in Equation 1.

When the number of logged-on users on the system is small, it is possible for a few users to have an inordinately large effect on the aggregate user work, and hence bias the results. To minimize bias, all data with fewer than twenty-five logged-on users were excluded from the analysis. Furthermore, to minimize the effect of changes in the aggregate user work at different times of the month, the data collected were separated into groups of six to eight consecutive days and analyzed separately. One repre-

sentative sample is used for IUP for each system, with least squares fitted third-order negative exponent polynomial for IUP.

Thursday, June 17, 2010

Many SaaS providers are adding customization and scripting that blurs the lines of what’s a cloud, and what’s an app, and what’s a programming language. Now that you can write code for Google Apps -- as in this example of a script that sends custom driving directions to everyone in a spreadsheet -- the distinction is less and less clear.

The turnkey/tuning tradeoff.

Thursday, June 17, 2010

Unfortunately, there’s a tradeoff here -- everyone wants fast, cheap, and customized. You can only have two. The more tailored your IT systems are, the more you’ll be paying for them and the slower they’ll be. At the same time, if you use the same applications and processes as everyone else you may sacrifice important differentiators.

http://www.flickr.com/photos/andrewparnell/2738598951/Thursday, June 17, 2010

An increasingly important criteria is the ability to connect existing systems to new ones. Whether this is legacy applications (for authentication, data exchange, or single sign-on); or to third-party customers and partners, the ability to link your systems to others is a huge deal.

Thursday, June 17, 2010

This is one of the reasons a thriving ecosystem around a platform is so important -- because it’s an indicator of ability to develop to the platform, as well as a starting point for integration and extension.

http://www.flickr.com/photos/oobrien/7597395/Thursday, June 17, 2010

Then there’s compliance and security. This may include geographic and legislative issues (where you can put your data) as well as auditing and logging (some industries require physical collection by a separate system.)

Thursday, June 17, 2010

The economics of renting versus buying apply here, too, since the investment is approaching zero. The traditional way of looking at this is to compare an upfront investment to the rental model of a lesser investment (integration, training) and a pay-as-you-go cost.

Several things have changed in recent years in this respect. First, the upfront investment of a pay-as-you-go model has dropped: everyone knows how to use a browser; everyone can access things remotely; vendors have trial models; and so on. So it takes longer to get to the point where it’s cheaper to run your own thing.

First, there’s bare metal.

Thursday, June 17, 2010

It’s pretty cheap. The vast majority of costs -- sometimes as much as five times the cost of the hardware -- come from operating it, powering it, cooling it, and so on.

Virtualization lets us put many workloads on a single machine

http://www.flickr.com/photos/stawarz/3538910787/Thursday, June 17, 2010

Once  workloads  are  virtualized,  several  things  happen.  First,  they’re  portable

http://www.flickr.com/photos/swimparallel/3391592144/Thursday, June 17, 2010

Second,  they’re  ephemeral.  That  is,  they’re  short-­‐lived:  Once  people  realize  that  they  don’t  have  to  hoard  machines,  they  spin  them  up  and  down  a  lot  more.

http://www.flickr.com/photos/genewolf/147722350Thursday, June 17, 2010Which  inevitably  leads  to  automa3on  and  scrip3ng:  We  need  to  spin  up  and  down  machines,  and  move  them  from  place  to  place.  This  is  hard,  error-­‐prone  work  for  humans,  but  perfect  for  automa3on  now  that  rack-­‐and-­‐stack  has  been  replaced  by  point-­‐and-­‐click

http://www.flickr.com/photos/pinkmoose/3278324276/Thursday, June 17, 2010

Automa7on,  once  in  place,  can  have  a  front  end  put  on  it.  That  leads  to  self  service.

These  are  the  founda7ons  on  which  new  IT  is  being  built.  Taken  together,  they’re  a  big  part  of  the  movement  towards  cloud  compu7ng,  whether  that’s  in  house  or  on-­‐demand.  If  you  do  all  these  things,  you’re  running  what  many  people  call  a  “private  cloud”

Virtual private clouds(feels like yours)

Thursday, June 17, 2010

If you like the virtualization, but don’t like having to carry a screwdriver around, virtual private clouds may be right for you.

In this approach, you have a machine that feels like it’s your own -- complete with a private IP address and so on. If you want to connect it to the Internet, you do so yourself; it’s just like virtual infrastructure, but someone else is running it.

In fact, the experiment is even more compelling: Desktop OCR took about 30 minutes per page to properly scan, read, resize, and format each page – which means that it would have taken nearly a year, and cost $123 in power, to do the work on a single machine.

In an IaaS model, you’re getting computers as a utility. The unit of the transaction is a virtual machine. It’s still up to you to install an operating system, and software, or at least to choose it from a list. You don’t really have a machine -- you have an image of one, and when you stop the machine, it vanishes.

Most applications consist of several machines -- web, app, and database, for example. Each is created from an image, and some, like databases, may use other services from the cloud to store and retrieve data from a disk

Or you can create several machines at each tier, and use a load balancer to share traffic between them. These kinds of scalable, redundant architectures are common -- nay, recommended -- in a cloud computing world where everything is uncertain.

The second kind of cloud is called Platform as a Service. In this model, you don’t think about the individual machines—instead, you just copy your code to a cloud, and run it. You never see the machines. In a PaaS cloud, things are very different.

- You write your code; often it needs some customization.- That code runs on a share processing platform- Along with other people’s code- The code calls certain functions to do things like authenticate a user, handle a payment, store an object, or move something to a CDN- To keep everything running smoothly (and bill you) the platform has a scheduler (figuring out what to do next) and a governor (ensuring one program doesn’t use up all the resources) as well as a console.

Here’s a shot of some code running in Google App Engine. I only know that I’m paying by CPU-hour, or for units like bandwidth, email, or storage. This could be one machine whose CPU was used 8%, or a hundred, or a thousand. I don’t know.

It’s a true, pure utility because you pay for what you use.

This is a very different model from IaaS. On the one hand, it’s more liberating, because you don’t have to worry about managing the machines. On the other hand, it’s more restrictive, because you can only do what the PaaS lets you.

IaaS and PaaS differences

IaaS

Any operating system you want

Limited by capacity of virtual machine

Scale by adding more machines

Many storage options (file system, object, key-value)

PaaS

Use only selected languages and built-in APIs

Limited by governors to avoid overloading

Scaling is automatic

Use built-in storage (Bigtable, etc.)

Thursday, June 17, 2010

In the case of Google’s App Engine, you have to use their functions and store things in the way they want you to. You get great performance from doing so, but it probably means rewriting your code a bit.

The third kind of “cloud” app is really just a new software delivery model; I hesitate to call them clouds at all, actually. It’s SaaS. And it’s what most people outside of IT think of as “cloud computing.”

Thursday, June 17, 2010

The third kind of cloud is called Software as a Service, or SaaS. Some people argue that this isn’t a cloud at all, just a new way of delivering software. But it’s also what the masses—the non-technologists—think cloud computing means. The problem is that SaaS is pretty much synonymous with “dynamic website” or “the Internet” these days. Nevertheless, if an ISV is shipping software on discs still, their days are numbered.

One last thought about building your own, rather than building it as part of a bigger platform: Adoption is what matters. There’s a build-your-own dilemma: If you create a new environment, you need to change users’ patterns.

Thursday, June 17, 2010

Thursday, June 17, 2010

The whole reason you deploy apps is so that you can focus on the things you do best: whatever adds the most value to your business.

Thursday, June 17, 2010

You also deploy apps to handle processes you didn’t want to do yourself anyway.

“What information consumes is rather

obvious: it consumes the attention of its

recipients. Hence, a wealth of information

creates a poverty of attention and a need

to allocate that attention efficiently among

the overabundance of information sources

that might consume it.”

Herbert Simon

Thursday, June 17, 2010

The problem isn’t delivery: we have plenty of options for that. It’s adoption.

http://www.flickr.com/photos/gideon/6582069/Thursday, June 17, 2010

But your users might well not adopt the app despite your best efforts, because they don’t like it, or don’t notice it, or aren’t adopting it in the way you’d hoped.

http://www.flickr.com/photos/roebot/4271975019/Thursday, June 17, 2010

At the same time, you’re seeing what tools and processes are getting adopted -- what’s working? what’s popular? -- and doubling down on those things.

Here’s the simplest possible analytics model.

For transactional sites

Can people buy things?

Thursday, June 17, 2010

Remember the four kinds of sites? You need to analyze and optimize the app you’re delivering in the same way.

A site that wants visitors to complete a transaction—normally a purchase—is transactional. There’s an “ideal path” through the site that its designers intended, resulting in a goal or outcome of some kind. The goal isn’t always a purchase; it can also be enrollment (signing up for email) or lead generation (asking salespeople to contact them), and can happen either online or off. For e-commerce, that’s whatever your transaction consists of.

For media sites

Are ads loading quickly and successfully clicked through?

Is content loading fast enough for visitors?

Thursday, June 17, 2010

These sites offer content that attracts and retains an audience. They make money from that content through sponsorship, advertising, or affiliate referrals. Search engines, Adwords-backed sites, newspapers, and well-known bloggers are media properties. For media sites, that’s making money from ads.

For collaboration sites

Can visitors contribute (posting content, voting?)

Is bad content being mitigated (trolling, spam)?

Thursday, June 17, 2010

On these sites, visitors generate the content themselves. Wikis, news aggregators, user groups, classified ad listings, and other web properties in which the value of the site is largely derived from things created by others are all collaborative.

For collaboration, that’s creating and curating content.

For SaaS sites

Are your end users productive?

Are they making fewer mistakes?

Is the site working during customers’ business hours?

Thursday, June 17, 2010

These sites are hosted versions of software someone might buy. SaaS subscribers expect reliability and may pay a monthly per-seat fee for employees to use the service. Revenues come from subscriptions, and a single subscriber may have many user accounts. On some SaaS sites, users are logged in for hours every day.

For SaaS sites, that’s productivity and an error-free experience.

The closest your app will be to one of the four “public” websites is a SaaS site. Here’s the business model for a SaaS site.

(Insert your app here)

Are they adopting the app at the rate you expect?

Are they abandoning the old ways?

What are they using most or neglecting?

How productive are they?

Where are they making mistakes?

?

Thursday, June 17, 2010

What does your adoption and usage map look like?

Optimization & change

Thursday, June 17, 2010

Optimization involves a constant cycle of collection, reporting, communicating and sharing the data, tying it to business processes, changing the system, and repeating.

The good news:you can experiment easily

We stop worrying about ROI when I is zero.

Thursday, June 17, 2010

http://www.flickr.com/photos/steven_wong/2440355239/Thursday, June 17, 2010

They’re not dictating and restricting; rather, they’re regulating usage to ensure a good balance of risk and experimentation

Beyond adoption: outcomes

Deployment Awareness AdoptionBusinessoutcomes

Thursday, June 17, 2010

Once you’ve got adoption, you’re not done: the same tools will let you measure the outcomes:- More productivity- Abandonment of old/bad methods- More leads- Lower cost- Fewer errors- Etc.
