Tune into the Cloud

Having an up-to-date and easy-to-execute exit strategy is much more important in the cloud than it was in the past

In the cloud lock-in is often a greater concern than lock-out*, but both should be top of mind for organizations looking to deploy cloud seriously, or better said, for organizations that want to deploy cloud for serious business.

Lock-in is the phenomenon that it is often difficult (lengthy and expensive) for user organizations to switch suppliers, often because after some time the software becomes so closely linked with the way the organization works that saying goodbye to the vendor becomes virtualy impossible. It is no coincidence that there are only two industries (IT vendors and drug dealers) that routinely refer to their customers as "users."

As long as the supplier still has his sights set on expanding its market share, lock-in is often not a problem. But by the time the revenue from the installed base becomes more important than winning new customers, customers often start to encounter regular price increases, increasingly stringent terms of use and less responsiveness from its vendor. With cloud computing that tipping point is still far away (currently the cloud market makes up only about 3 to 5 % of total IT market spend), but it is also an industry where lock-in has a lot more impact that in traditional IT. In the cloud customers are - for the whole service stack (application, middleware and underlying hardware) dependent on their supplier. Unless when the application they use is also offered as a cloud service by other providers, but that is not a very common model for SaaS offerings. Today SaaS offerings can typically only be bought directly from the authoring organization.

But also in the cloud lockout must be avoided. Just imagine a scenario of a typical cloud provider, who controls the entire stack from application to hardware, unexpectedly going out of business (like a Nirvanix, that had a relatively soft landing and was able to give two weeks notice to its customers) or if that provider decides it does not want to serve a certain company or country anymore. Like how several cloud providers locked out Wikileaks after the first press leaks, or a vendor like Mega Upload, where regular customers lost all access to their data after a judge ordered them to shut down completely based on media industry accusations. But same can happen if a reputable large provider decides some of its products are no longer strategic. The big difference between the cloud and traditional in-house hardware and software is that as soon as the provider stops it service, the ciustoemr is immediately out of business. This is very different form traditional IT where resources could often still be used for years, even if the hardware is out of warranty and the software out of support.

Having a plan B and an up to date and easy to execute exit strategy is therefore much more important in the cloud than it was in the past. Agreeing upfront what parties will be allowed and enabled to continue the services if the original provider no longer can (or no longer wants to do so). At this moment this is only pragmatically possible for open source solutions that are already offered by multiple parties, but in some countries hosting providers are putting standard rules and arrangements in place ≈to move customers from one hosting provider to another, in case the need arises, including any commercially licensed standard software.  But for traditional SaaS there is still a distinct risk f being "Locked out of Heaven". So for now the advice from one of my first bogs ever, still stands: Any good cloud strategy must start and end with an exit strategy".

* Locked Out of Heaven is an album by Bruno Mars, an artist whose popularity grew even faster than the popularity of cloud computing. But this album is not a collection of different songs. It is a compilation of several remixes of the same number, allowing the customer to choose the delivery method that he likes best for his situation.

A critical component of any IoT project is what to do with all the data being generated. This data needs to be captured, processed, structured, and stored in a way to facilitate different kinds of queries. Traditional data warehouse and analytical systems are mature technologies that can be used to handle certain kinds of queries, but they are not always well suited to many problems, particularly when there is a need for real-time insights.

Big Data engines are powering a lot of service businesses right now. Data is collected from users from wearable technologies, web behaviors, purchase behavior as well as several arbitrary data points we’d never think of. The demand for faster and bigger engines to crunch and serve up the data to services is growing exponentially. You see a LOT of correlation between “Cloud” and “Big Data” but on Big Data and “Hybrid,” where hybrid hosting is the sanest approach to the Big Data Infrastructure pro...

He also highlighted how IoT can revitalize and restore outdated business models, making them profitable ...
We all know the latest numbers: Gartner, Inc. forecasts that 6.4 billion connected things will be in use worldwide in 2016, up 30 percent from last year, and will reach 20.8 billion by 2020. We're rapidly approaching a data production of 40 zettabytes a day – more than we can every physically store, and exabytes and yottabytes are just around the corner. For many that’s a good sign, as data has been proven to equal money – IF it’s ingested, integrated, and analyzed fast enough. Without real-ti...
I wanted to gather all of my Internet of Things (IOT) blogs into a single blog (that I could later use with my University of San Francisco (USF) Big Data “MBA” course). However as I started to pull these blogs together, I realized that my IOT discussion lacked a vision; it lacked an end point towards which an organization could drive their IOT envisioning, proof of value, app dev, data engineering and data science efforts. And I think that the IOT end point is really quite simple…
