Flying South

Flying South

My neighborhood is home to a host of birds, many of which fly south during the winter months. With spring in bloom, I always look forward to the return of the various avian travelers who dart and weave all over the open fields near my home. That's the kind of migration I look forward to.

In the software world, there's a less appealing form of migration, one we can never truly get away from. That's the migration of code and servers from one version to the next.

Some migration efforts have been a direct result of the evolution of the EJB and J2EE specifications. In the earliest incarnations, much of the deployment mechanism was left up to the container vendors. While EJBs were, in theory, portable, for all practical purposes, it was an adventure to move them from one container to another - which we often had to do as organizations explored the emerging container vendors, back before it became a two-horse race.

XML deployment descriptors were a big step in the right direction, allowing the IDE vendors to do a better job of deployment to multiple platforms. Part of that was just standardization, but part of it was driven by other necessities.

Probably the biggest driving force in this evolution was the development and standardization of Container Managed Persistence. As containers became more sophisticated, and Container Managed Relationships and EJBQL evolved, the deployment descriptors and mechanisms changed accordingly. Fortunately, the J2EE specification is now a bit more stable, and updates come at a more benign pace. Unfortunately, that doesn't insulate us from the other source of migration - vendor version updates.

The J2EE application server platform has grown by a process of accretion - last year's differentiators are this year's core product. JMS is a great example of that. All vendors try to innovate, and introduce new features that are not quite part of any specification. JCA is a perfect example. BEA supported it from the outset, but added functionality (asynchronicity, among other things) and then lobbied the JCP to include it in the next release of the specification.

All of which is good, up to a point - the nightmare of migrating an application from one version of the software to another. In some cases, such as when major specification changes occur, it behooves an organization to examine its application and see if it's time for refactoring.

But in other cases, the move to the next version of software is more painful than it should be. For example, it seems the console changes each time we get a new release of WLS. That adds to administration headaches, even if you just want to redeploy the old application.

What we really need is to fix the deployment standard - with a common interface for the core specification. There should be a common descriptor, a common interface (or interfaces, one thick console, and swing based, one in JSP) that can be expanded, but not changed. Any new, proprietary functionality would be added as extensions, and managed by the console.

In the meantime, we have a new release of WebLogic Server. The early version that I've seen has a great deal to offer, even if it will take work to migrate to it. In particular the revamped Workshop is going to give MS Visual Studio a run for its money.

Even the bird migrations are not without a downside. As I look out my window, I see the turkey buzzards are back too. Still, I look forward to seeing most of the migrating creatures. Migrations are like that, even the best ones.

To Really Work for Enterprises, MultiCloud Adoption Requires Far Better and Inclusive Cloud Monitoring and Cost Management … But How? Overwhelmingly, even as enterprises have adopted cloud computing and are expanding to multi-cloud computing, IT leaders remain concerned about how to monitor, manage and control costs across hybrid and multi-cloud deployments. It’s clear that traditional IT monitoring and management approaches, designed after all for on-premises data centers, are falling short in ...
We are seeing a major migration of enterprises applications to the cloud. As cloud and business use of real time applications accelerate, legacy networks are no longer able to architecturally support cloud adoption and deliver the performance and security required by highly distributed enterprises. These outdated solutions have become more costly and complicated to implement, install, manage, and maintain.SD-WAN offers unlimited capabilities for accessing the benefits of the cloud and Internet. ...
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...

Combined with his ability to communicate complicated scientific concepts in a way that consumers and scientists alike can appreciate, John is a sought-after speaker for conferences on the forefront of healthcare science,...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
