There has been much debate lately on what exactly WSDL's purpose is, and much
of that debate has focused on whether WSDL is an interface definition
language (IDL), or whether WSDL is better used to specify message-level
contracts (without any associated operational semantics).
In this article we present an argument that dealing with WSDL as a
message-level contract description language is the right way to go for
building loosely coupled Web services.
Interfaces and Contracts
Before we delve into the specifics of how WSDL should be used, we need to
understand the difference between a classic interface and a contract. By
understanding the different problems that each solve we can begin to form a
picture of when it is appropriate to use one or the other.
Let's start by briefly recalling exactly what is meant by an interface.
In an object-oriented view of the world, appli... (more)
Web services have evolved from plain application-integration enablers to
value-added stand-alone functionality providers such as getting a quote to a
comprehensive business function like processing orders. Enterprises are
exploiting this new revenue model by offering such business functions as
services on usage basis. Information sharing instances such as Amazon's
e-commerce services have helped in the creation of new powerful solutions
using business functions as services.
Why Do We Need Adaptation in Web Services?
In the vision of e-business, it becomes important to address the dynamic
nature of business environments. As third parties access more and more
business functions, the richness of Web services offered should be adequately
addressed. With Web services having to participate and cooperate in a
networked system, they may need to frequently join or leave a pro... (more)

The next edition of the HP Discover Performance podcast series brings
together two top cloud evangelists from the recent HP Discover 2012
Conference to discuss the specific concepts around converged cloud,
information clouds, and hybrid services delivery.
We’re joined by Paul Muller, the Chief Software Evangelist at HP, and
Christian Verstraete, Chief Technologist for Cloud Strategy at HP. The
discussion is moderated by Dana Gardner, Principal Analyst at Interarbor
Solutions. [Disclosure: HP is a sponsor of BriefingsDirect podcasts.]
Here are some excerpts:
Gardner: You’ve separated the notion of hybrid computing and hybrid
delivery. Can you help me understand better why they're different, and what
HP means by hybrid delivery?
Verstraete: Hybrid computing typically is combining private and public
clouds. We feel that many of our customers still have a traditional

For Valentine's Day, here's a lighthearted look at the "relationship" between
two complementary technologies: service virtualization and cloud dev/test
labs.
Dear Service Virtualization,
Hey, I know it's been a while since we started being "a thing." When we met,
everyone said you were just mocking, and that I wasn't real enough to make a
living, with my head in the clouds. Yet, here we are, a few years later.
Service Virtualization, you complete me.
As a young Dev/Test Cloud, I always wanted to try new things. And what better
use for Cloud than experimenting with software for startup companies? I was
flexible, I thought I had the capacity to handle anything. I'd stay up all
night studying or partying, but sometimes I'd crash. So what if some college
kid's cloud-based photo-sharing site experiment goes down? It wasn't going to
impact anyone's life.
But when it came... (more)

The goal of Microservices is to improve software delivery speed and increase
system safety as scale increases. Microservices being modular these are
faster to change and enables an evolutionary architecture where systems can
change, as the business needs change. Microservices can scale elastically and
by being service oriented can enable APIs natively. Microservices also reduce
implementation and release cycle time and enables continuous delivery. This
paper provides a logical overview of the Microservices Reference Architecture
that highlights various sub systems needed to support Microservices
deployment and execution.

Microservices Articles By Liz McMillan  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...

Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that these improvements led to the development of new ways to utilize coal. In his session at 19th Cloud Expo, Mark Thiele, Chief Strategy Officer for Apcera, compared the Jevons Paradox to modern-day enterprise IT, examin...

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.

Jun. 8, 2019 06:00 AM EDT Reads: 6,100 | By Pat Romanski  In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise. Jun. 1, 2019 04:00 AM EDT Reads: 5,929 | By Elizabeth White  The Software Defined Data Center (SDDC), which enables organizations to seamlessly run in a hybrid cloud model (public + private cloud), is here to stay. IDC estimates that the software-defined networking market will be valued at $3.7 billion by 2016. Security is a key component and benefit of the SDDC, and offers an opportunity to build security 'from the ground up' and weave it into the environment from day one.

May. 30, 2019 07:30 PM EDT Reads: 11,501 | By Pat Romanski  DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In their Day 3 Keynote at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, and Mark Lav... May. 29, 2019 05:00 PM EDT Reads: 7,641 | By Jason Bloomberg  Many organizations are now looking to DevOps maturity models to gauge their DevOps adoption and compare their maturity to their peers. However, as enterprise organizations rush to adopt DevOps, moving past experimentation to embrace it at scale, they are in danger of falling into the trap that they have fallen into time and time again.
Unfortunately, we've seen this movie before, and we know how it ends: badly.
May. 25, 2019 04:15 PM EDT Reads: 6,607 | By Mehdi Daoudi  TCP (Transmission Control Protocol) is a common and reliable transmission protocol on the Internet. TCP was introduced in the 70s by Stanford University for US Defense to establish connectivity between distributed systems to maintain a backup of defense information. At the time, TCP was introduced to communicate amongst a selected set of devices for a smaller dataset over shorter distances. As the Internet evolved, however, the number of applications and users, and the types of data accessed and... May. 25, 2019 06:00 AM EDT Reads: 4,551 |
