In regards to the additional products, we have a skin installed and we have a product that we had custom developed for us that connects to a PostgreSQL database. We've looked at slow PostgreSQL queries causing problems and have not been able to find an issue. We've also tested for the case where the PostgreSQL server is down and have not been able to create an issue. We therefor...

Distribution and communication between applications and services is a central concept in modern application architectures. In order to profit from distribution you have to keep some basic principles in mind – otherwise you can easily run into performance and scalability problems. Durin...
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 ...

The Gartner Hype cycle research shows Cloud Computing as being on the peak of expectations… the very top of the hype bubble roller coaster.
Vendors are looking for something to sell, and the consolidation of the data center, reducing operational cost and economy of scale are as conv...
Justifying the extra investment for developing a single-purpose service – a service expected to solve only one large business problem - instead of putting the single-purpose logic inside a non-service-oriented application can be challenging. Reuse, the most popular motivation for creat...
Small and medium businesses (SMBs) that have previously considered virtualization in the cloud but decided that it is too expensive or simply not viable should think again. Virtualization and cloud computing enables SMBs to green their operations and build IT infrastructures that are a...
While there’s certainly no shortage of opinions on the future of SOA, the reality is that SOA is very much alive. The core principles of what SOA can do in terms of cost savings, increased productivity, and the virtual elimination of information and application silos won’t go away. How...
ESB products emerged around 2002 from message-oriented middleware (MOM). Faced with market domination by IBM, MOM vendors were the first to jumpstart the ESB concept with the aim of developing a unique selling proposition. They added Web service and EAI capabilities on top of existing ...
One of the main concerns among IT architects planning an implementation of an enterprise data virtualization layer in their service-oriented architecture (SOA) or overall information system is the performance of the participating data services. Performance becomes particularly importan...
SOA C-level skeptics come in all shapes and sizes. They can be in any industry or any government agency. They can be close friends who “really like you” and no matter what, will invite you to their backyard barbeques. However, despite their differences or that fact that they may be you...
The "reset economy" has moved the business and operations maturity process of IT from "nice to have" to "must have," if costs are going to be cut without undermining operational integrity.
Businesses tend to focus their architecture on efficiency instead of agility. This clear distinction between optimising for the known versus optimising for the unknown inherently counteracts on businesses in their effort to seize any of the new opportunities that arises around them.

Look in the network closet in any good-sized company today and you’ll find a wide assortment of network gear: firewalls, switches, gateways, routers, hubs, bridges, the list goes on and on. Each of these devices essentially either directs or secures the packets that form the automobile...
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...
Reducing the cost of IT management is one of the primary pressures for most organizations. One of the most common ways to reduce such costs is to enable the reuse of applications that developers have already created and configured for the enterprise. In the past decade, especially in t...
Cloud computing is slowly gaining credibility and traction in the enterprise world. As giants such as Google and Amazon productize their massive cloud infrastructures, moving enterprise applications to the public cloud seems a more realistic possibility. The advantages of an enterprise...
We can visualize resource starvation using an elaborate rendition of the Dining Philosophers Problem. This classic metaphor of resource allocation among processes was first introduced in 1971 by Edsger Dijkstra in his paper “Hierarchical Ordering of Sequential Processes.” It’s been a m...
Many enterprises are working with service-oriented architecture (SOA) initiatives using a variety of approaches. Regardless of the specific approaches undertaken, the intent is to build services and business processes for the organization to realize the benefits of SOA. However, you ne...

Whenever IT professionals discuss the benefits of SOA – full utilization of IT resources, reduced infrastructure costs, and the agility to deliver new services quickly – they usually issue a caveat. They warn potential adopters of the inherent complexity of SOA, and point out that unle...
For many people, even entire organizations, the approach to education seems to be along the lines of learning facts, figures, details, tools and standards. This results in a shallow understanding of both the business problem and the new Service Oriented Architecture (SOA) strategies av...
