Innovative service technologies are becoming valuable assets for businesses that need to stay competitive in the face of increasing globalization and market complexity. While computer processing power is becoming faster and cheaper, search engines, instant messaging, and social media channels are generating floods of information that escalate demands for consumable and accessible data.
As the world's economies engage one another through offshoring, outsourcing, and supply chaining, localization is required to accommodate different currencies and languages. Globalization, recession, invention, and communication are some of the driving forces behind a next generation of technologies and practices that revolve around software programs designed in accordance with the paradigm of service-orientation. Such programs, referred to as "services," are expected to do more for less with greater efficiency in order to meet business challenges head-on.
We have reached a stage in the evolution of service-oriented computing where modern service technology innovation is building upon mature service platforms at the same time that proven delivery techniques and design patterns are building upon an established service-orientation paradigm. These developments have made it possible to create service-oriented solutions of unprecedented sophistication.

SOA and service-orientation have laid the foundation for a variety of emergent service technology innovations such as cloud computing and Big Data, while the original building blocks of SOA and service-orientation (which include BI, BPM and MDM, among others) continue to evolve by embracing fundamental service technologies, concepts and practices.
Preparation for Live Mobile Hacking with an OFM 12c red stack
On March 4th, I am to present – together with ADF and Mobile Application Framework expert Luc Bors – a live development demo session at the EMEA Oracle Fusion Middleware Partner Forum in Budapest, Hungary. Luc and I are in the middle of our preparations for this event. And I thought perhaps it would be nice to share some of the background for this session.
It all started in the Fall as Jürgen Kress, responsible at Oracle for Fusion Middleware Partner Adoption EMEA, sent out a call for papers for the Forum, looking for proposals for presentations and other types of sessions. Luc and I prepared a proposal for a session where we would do live development (always appealing for the audience and somewhat nerve racking for the presenters) and show the development of a mobile app (using Oracle MAF) on top of a mobile back end (created using SOA Suite 12c and its REST capabilities). Luc and I have done similar sessions in the past. They can be a lot of fun – and be quite stressful because of all the things that can and typically will go wrong.
So, do you work with Oracle SOA Suite?, that’s great because we also do, every single day since a long time ago. As Oracle professionals, we’ve seen the SOA stack grow, change, incorporating new products and technology with each version, from 10g to 12c.
We’re Rolando Carrasco (Oracle ACE) and Arturo Viveros (Oracle ACE Associate), the SOA Myth Busters from Mexico, and as we go with this series we will put to the test a number of questions, myths and urban legends regarding both SOA & the Oracle SOA Platform in seek of finding out which myths are true and which are not.
SOA & Web Service Technology
It’s a secret to nobody that Service Oriented Architecture and Web Services go hand by hand. However, the relationship between these two is very often and very awfully misunderstood. Thus, there are plenty of myths and misconceptions surrounding this particular topic, which we will attempt to tackle and clarify within this episode.
In this article I will talk about my first conclusions and my point of view regarding Microservice Architectures. As there is still quite a lot of confusion and debate out there on this topic, I will try to describe with my own words what Microservice Architecture is, how does it differ from typical Service Oriented Architectures (SOA) and what design principles and practices governs it.
What is a Microservice Architecture?
In the article written by Fowler and Lewis, Microservice Architecture is described as following:
Microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies
There's no doubt that "the cloud" is coming, even in the relatively conservative world of mission-critical Oracle platforms.
At the end of 2012 I took a trial of what was then "Java (or WebLogic) as a Service" (now known as "SaaS Extension"). Back then I wasn't hugely impressed - yes, I could deploy a simple web app, but the WebLogic environment was very heavily constrained and almost entirely hidden from the administrator - no WebLogic console, no WLST, minimal logs. As a result as soon as I tried to deploy something non-trivial, in this case Apache Roller (the software running this blog), I ran into all sorts of class white-list issues and with little debug information so I quickly gave up in despair!
