An important part of the Web service vision being promoted by the Worldwide Web Consortium (W3C) and others is that of automated service discovery, the idea being that when we need a particular kind of service we will no longer have to go out and search for it manually; our computer will do it for us. Nowhere is this more necessary than in scientific computation. International collaboration here is already the norm and is increasingly being supported by the Grid, where specialized resources are connected by high-speed, high-bandwidth networks. To realize this vision requires mechanisms for describing what services actually do, and for reasoning about those descriptions in the presence of a user's problem. MONET: Mathematics on the NET The MONET project is a two-year investigation into how service discovery can be performed for mathematical Web services, funded by the ... (more)

BPEL Processes and Human Workflow

Business Process Execution Language (BPEL), one of the key technologies for Service Oriented Architecture (SOA), has become the accepted mechanism for defining and executing business processes in a common vendor-neutral way. Companies ranging from Oracle, IBM, Microsoft, SAP, and BEA to smaller organizations such as Fuego and Lombardi have committed to BPEL as a building block for SOA. BPEL, which has been designed specifically for defining business processes, supports typical interactions such as synchronous and asynchronous operation invocation, sequential and parallel flows, message correlations, fault and compensation handlers and activities triggered by events. Business processes often require human interactions as well. Since the BPEL specification doesn't address them, you might think BPEL isn't suitable for business processes that involve people. But that's n... (more)

The Security of Popular Cloud Storage Sites

For enterprises moving more business and customer data to the cloud, investigating and selecting an online storage solution can be a challenging task. A primary concern is the level of data security offered by the sites being considered. While the theme holds true across all of the major providers (Box, DropBox, SkyDrive), for the purpose of illustration I'll focus on DropBox since it is arguably the most popular site boasting over 100 million users. Here is where some of the concerns begin; DropBox experienced a major security breach in July 2012, specifically involving user passwords. In response to the attack, DropBox attempted to improve password security by implementing two-factor authentication. But just last month though, a pair of researchers released a paper claiming they had reverse-engineered the DropBox application, providing details for how hackers c... (more)

IT Transformation Requires One Step After the Other

I speak with a number of Business Leaders, CIOs, IT leaders and IT staff about this very issue. The subject of IT Transformation is one that keeps coming up. Yet, it seems as illusive as it is alluring. Looking For Direction The technology (specifically IT) world is becoming more complex and challenging every day. I speak with a number of Business Leaders, CIOs, IT leaders and IT staff about this very issue. The subject of IT Transformation is one that keeps coming up. Yet, it seems as illusive as it is alluring. The prospect that it could bring is enough motivation for many to try. For most IT organizations, the capacity to take on the challenge seems out of reach. Many still struggle to keep up with day-to-day operational challenges. Let those fall and nothing else matters. On the flip side, doing nothing is not an option either. Warning: This is hard work and is mu... (more)

Future-Proofing Solutions with Coarse-Grained Service Oriented Architecture

Web services and service-oriented architectures are transforming application construction. The ubiquity of Web services support by all leading platform venders brings the promise of a flexible application environment with simplified interface techniques, location transparency, and platform-neutral interoperability. This dynamic infrastructure brings about a new implementation approach, the service-oriented architecture. However, to date most Web services projects have really only created simplified communication mechanisms for the invocation of those same old complicated legacy interfaces that we have always had. To truly realize the creation of service-based components, a new design approach is needed, one that produces simple, straightforward coarse-grained service interfaces that conceal the ugliness of the legacy low-level interfaces. Designing coarse-grained i... (more)

Design Strategies for Web Services Versioning

Application versioning has always been a challenge for the developer community. With the introduction of Web services, this issue becomes even more difficult as developers are dealing with a more distributed set of components that aren't necessarily under their control. A robust versioning strategy is needed to support multiple versions of Web services in development. This can allow for upgrades and improvements to be made to a Web service, while continuously supporting previously released versions. The right versioning strategy can maximize code reuse and provide a more manageable approach to the naming, deployment, and maintenance of your Web services. The issue of versioning is a complicated one, and this article does not attempt to answer every question surrounding the versioning of XML and Web services. However, there are some key approaches and design practice... (more)

Berners-Lee Pockets $1.2m Prize

Berners-Lee was reportedly selected unanimously out of a field of 78 innovators from 22 countries for "an innovation that directly promotes people's quality of life, is based on humane values and encourages sustainable economic development." They're going to make a fuss over him in Helsinki on June 15 at the inaugural Millennium Technology Conference on Future Technology. In saluting Berners-Lee, a Brit ex-pat, the Finns are snubbing one of their own, the inestimable Linus Torvalds. ... (more)

Commercial vs Federal Cloud Computing

Government Cloud Computing on Ulitzer Frank Gens of IDC recently provided an excellent overview of the the new "Cloud Computing Era". His description of "cloud computing" and "cloud services" really highlights the difference between the commercial cloud computing market and the Federal cloud computing market. (Paraphrased from Frank Gens' article) When people talk about “cloud computing”, they are usually referring to things like software-as-a-service (SaaS) and storage or server capacity as a service. They may also talk about the many “non-IT” business and consumer services like shopping, banking, selling, collaborating, communicating and being entertained. In reality, these things represent an on-line delivery and consumption model for business and consumer services. These users are not explicitly buying “cloud computing,” but the “cloud services” that are enabled b... (more)

Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value...
DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
Is advanced scheduling in Kubernetes achievable?Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations? In his session at @DevOpsSummit at 21st Cloud Expo, Oleg Chunikhin, CTO at Kublr, answered these questions and demonstrated techniques for implementing advanced scheduling. For example, using spot instances and co...

Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches. In his session at DevOps Summit, Gordon Haff, Senior Cloud Strategy Marketing and Evangelism Manager at Red Hat, discussed why containers should be paired with new architectural practices such as microservices rathe...
