Reseña del libro "the agile architecture revolution: how cloud computing, rest - based soa, and mobile computing are changing enterprise it"
this book lays out a multidimensional vision for change based on five broad organizing principles called supertrends: 1. location independence: an abstraction fundamental to the virtualization inherent in clouds, whether they are public, private, or hybrid. mobile presence is also a critical aspect of location independence. think global buddy list, tied together with your mobile device, your instant messaging, and other indicators of your personal availability. if you can tell people youre available no matter where you are, thats part of the location independence supertrend as well. 2. global cubicle: the internet gave us the global village. take that idea to its logical extreme and you have the global cubicle. any two people anywhere in the world can work together, communicate, and socialize as though they were in the same room, or even the same cubicle. the telephone itself gave us our first glimpse of this capability. but now add the location independence along with ubiquitous computing (where every device is on the internet, wired or not), combined with the power of social media to bring people together in new ways. 3. democratization of technology: how do you buy it in your organization today? is anybody in your organization buying it via a mobile app store? or how about provisioning an ad hoc cloud instance using a personal credit card? or maybe downloading a free piece of software? this bottom - up acquisition of it is fast becoming the norm as the subscription - based pricing of saas meets open source meets the app store model. 4. deep interoperability: yes, this should work with that. thats why we have open standards. todays reality falls far short of the promise of open standards. remember how modems used to negotiate back in the day? one modem would call another and tell it how fast it could go. the receiving modem would respond with the fastest it could communicate. the two modems would negotiate, gradually proposing slower speeds until they could establish a solid connection. take this one - dimensional idea from the modem world and apply it to the multidimensional world of enterprise it, where any two pieces of software automatically negotiate with each other to establish seamless interoperability. 5 complex systems engineering: to achieve true agility, organizations must rethink integration entirely. governance now becomes the new mantra instead of integration. cios become cgos. static enterprise architecture frameworks give way to continuous business transformation best practices. business process management finally leaves the realm of the integration vendors, as organizations begin truly managing their business processes in order to achieve their goals in the context of an ever - changing business environment. this book lays out a multidimensional vision for achieving agile architectures, and the five supertrends are but one dimension. the book discusses crisis points that promise sudden, transformative change. soa, cloud, and mobile computing are not supertrends, but they weave their way across the five discussed here. and most important, the business of it is a critical part of the story, as how organizations spend money on it will continue to undergo radical change over the next ten years
