The IT industry is positioned to experience major technology shifts within the next few years as a result of the rise of cloud adoption. According to Gartner, more than $1 trillion in IT spending will be affected by the shift to the cloud by 2020 – making cloud computing “one of the mo...
The technology vendors and the hype clearly load up the term “private cloud” with everything and anything. However, the concept of private cloud computing has the potential to bring a huge amount of value to enterprise IT. That is, if we understand the right approach, and how to leve...
It’s Thursday morning, you’re the CEO of a large, publicly traded company, and you just called your executives into the conference room for the exciting news. The board of directors has approved the acquisition of a key competitor, and you’re looking for a call-to-action to get everyon...
While there are many attempts to fix the badly broken IT architectures within our enterprises, most ‘solutions’ just put another technology layer on top of the existing technologies in hopes that the technology will somehow fix the issues. As you may have guessed, it just makes things ...
Dave speak with eBizq about Cloud Computing and SOA Convergence. [[ This is a content summary only. Visit my website for full links, other content, and more! ]]
Yes, but it’s not the only driver. There can be substantial cost benefits when leveraging cloud computing but, as we pointed out, your mileage may vary. You have to consider the cost holistically with other factors, including strategic benefits that are typically harder to define but a...
Want to know what gets my blood pressure up? It’s when there’s both a huge shift in thinking around how we should do computing, namely cloud computing, and at the same time, there’s a bunch of information out there that causes confusion. As cloud computing hype spikes to a frenzy, so d...
The idea of governance is to provide command, control, discovery, and monitoring, as well as design and development support for services that make up your architecture, including on-premise and in the cloud, and either leveraging virtualization. Most people get that, but in some cases...
The Gartner Group just listed "9 ways to measure SOA success.” Not to take anything away from Gartner, but theirs is a pretty basic list, if you ask me. Indeed, these nine measurements are really about any successful architecture, using SOA approaches or not, which is fine. However, I...
Those who approach virtualization these days are often taken aback by the complexity of the architecture when faced with the number of layers they must deal with to deploy virtualization. Most typically consider virtualization around data center optimization or private clouds, and find...
The value of service-oriented architecture (SOA) is the concept of agility, or the ability to limit risk by managing change. Today, many enterprises are fighting to make this a reality, yet few approach SOA using the right methodologies and technology, and most have yet to define the r...
Earlier this month I attended the IBM Impact conference in Las Vegas. The core theme of Impact was "Smart SOA" and how cloud computing comes together in the enterprise, with the emphasis on private clouds. The core notion of private clouds for IBM is really about extending their expe...
One of the key concepts to consider when talking about services and cloud computing is the notion of coupling. We need to focus on this since, in many instances, coupling is not a good architectural choice considering that the services are not only hosted within separate data centers, ...
There is a lot going on in the cloud computing space, and SOA is clearly along for the ride. Indeed, there are many things that cloud computing providers (and that’s a rather big category these days) and those building SOAs can learn from each other. I’m just scratching the surface her...
The use of APIs pervades the emerging world of cloud computing. People find they can mix and match information from all sorts of sources to create an application that specifically meets their needs. Indeed, companies such as The Web Service are in the business of providing you with k...
Those with virtualization skills are in high demand right now. That makes them just as difficult to retain as it is to find and hire them. Indeed, as virtualization becomes more important to enterprise IT, those who understand VMWare, and other virtualization technology, as well as u...
Recently VMware announced the Mobile Virtualization Platform (MVP) aimed at handset vendors to enable mobile users to choose between two different platforms or phone numbers on a single handset. This technology, which I call "virtualization light," would enable users who had separate p...
So, I’m a computer guy. What the heck is capital? As defined by Wikipedia it’s: “…any liquid medium or mechanism that represents wealth, or other styles of capital. It is, however, usually purchasing power in the form of money available for the production or purchasing of goods, etcete...
As SOA moves from the project level to the enterprise, SOA architects and practitioners quickly realize the need to consider common services and data management issues. Today we seek the right approaches and the proper enabling technology and standards to provide our enterprises with a...
You need SOA governance, design time, and runtime. However, SOA governance does not come out of a box. Simply put, it's really a matter of people and processes put in place to ensure that the services are designed, deployed, and operated as effectively as possible. However, people and ...
As cloud computing emerges there is a lot of discussion about how to define cloud computing as a computing model. Maturity models have been published and debated, and providers clearly have a model for their own products. In attempting to define this better to my clients, I came up wit...
The Web is slowly changing from a visual resource designed to externalize information to people, to a non-visual resource that's able to facilitate machine-to-machine communications. The catalysts of this change are non-visual communications that are enabled using APIs, or Application ...
What will cloud computing bring to your bottom line? That's what we will determine in this step. In essence, this is the process of calculating the ROI for the formations of clouds around your enterprise. However, keep in mind that not all systems make sense to outsource, and you have ...
If you've been following me on Twitter, or through my other blogs, you already know that I made it to the SOA World Conference & Expo in San Jose, CA, which was collocated with Cloud Computing Conference & Expo. I did the keynote on Wednesday and then stayed around for some of the sess...
You’ve heard of downsizing and rightsizing, so how about Cloudsizing? As properly defined, Cloudsizing is: The improvement of efficiency and effectiveness of an organization through the selective use of computing resources that are delivered over the Internet. Simple but powerful, and ...
Many organizations out there don't really have to sell SOA. They understand that hype is the driver, and, in essence, leverage the thousands of articles and books on the topic to sell this architectural pattern. However, in most cases SOA has to be sold in the enterprise. If you're doi...
You've always heard that you "get what you pay for," but that does not seem to be the case with the new cloud computing movement, specifically with Web APIs. Some of the best services out there don’t need a credit card number, and I suspect that trend will continue until greater number...
I know, the economy is rough these days. Myself, I'm unwilling to look at my mutual funds until we're through this. However, when times are tough, markets normalize, and while the stock holders and venture capitalists out there are crying in their beers, now could be a great time to s...
As www.ProgrammableWeb.com points out, there are about two services or Web APIs added every week, and that rate continues to accelerate. There seems to be several types of providers. First are those that produce an API as an afterthought, such as a SaaS provider. Next there are the lar...
One of the things covered in the recent Burton report was an instance where a new CIO was needed to get SOA going. In essence, the culture needed to change in order to accommodate the changes required to get a SOA rolling, and thus they changed out their CIO to change the culture. If y...
As we build services/APIs for use within the enterprise or cloud computing, there seem to be two clear trends for those who are consuming the services/APIs: they want to leverage APIs that drive social networking, such as Twitter and Facebook, and they want to leverage complex, busines...
In the last two columns we talked about the emerging platform of the Web, and the use of Web APIs found through directories. Now I have something to show you that lives up to that hype, in essence a layer of technology, on-demand, that lives between the API provider and the API consume...
Here we go again. While the paint is still wet on this new Web 2.0 stuff, many SOA vendors and large analysts firms are calling their market SOA 2.0. It's one of the silliest things I've heard in a long while, and both the analysts and vendors who use this term should be ashamed of the...
We've all experienced the hype: "We're a SOA tool, and we're here to help!" However, most SOA vendors out there don’t understand the value of SOA, or even how to approach SOA. They focus on the tactical and not the strategic. Why? A tactical approach is easier for them to sell, and eas...
While the number of SaaS providers grows, as well as enterprise acceptance, we are really not breaking new ground. In essence, today's SaaS providers offer visual systems, meaning they communicate with a human being. They also provide a single visual interface, and the users have to ta...
We've seen the hype – dynamic applications created by combining remote services that combine both application behavior and data into on-demand business applications that are as easy to change as they are to create. The reality was more evolutionary than revolutionary, but today we are ...
According to the Burton Group, the issues around SOA are not so much about technology and complexity as they are about the people and the processes within an enterprise. Indeed, in a recent article by Jon Brodkin, some of these issues are highlighted. The core issue is that IT thinks t...
It's important to remember that there is a huge resource being created on the Web these days in terms of both services and content. This includes access to SaaS applications (that are better than their enterprise-bound counterparts), service marketplaces, and even mash-able application...
It doesn't take a rocket scientist to understand that mashups are moving from things that are conceptual and fun, to things that are productive and businesslike. The fact is, developers are leveraging mashups to solve all sorts of business problems these days, and the speed to producti...
It's what you don't see about the emerging Web that has everyone excited these days. Namely, it's the powerful application programming interfaces, or APIs. APIs are nothing new and have been traditionally cryptic and difficult to use. However, the advent of Web services along with the ...
