DevOps is speeding towards the IT world like a freight train and the hype around it is deafening. There is no reason to be afraid of this change as it is the natural reaction to the agile movement that revolutionized development just a few years ago. By definition, DevOps is the natural alignment of IT performance to business profitability. The relevance of this has yet to be quantified but it has been suggested that the route to the CEO's chair will come from the IT leaders that successfully make the transition to a DevOps model. If this still seems foreign to you, I recommend reading up on DevOps Blog from IT Revolution, the OpsCode Blog, and check out The Phoenix Project. Despite all the talk around simple monitoring tools, breaking through the walls between Dev and Ops still poses a real challenge. This is because of a misunderstanding around Operations real pu...

Pattern Principles: The Open-Closed Principle

Design patterns exploded onto the scene when the seminal work, Design Patterns: Elements of Reusable Object-Oriented Software, was published in 1994. Since that time, numerous books on patterns have been written, conferences devoted solely to the patterns movement have emerged, and entire Web sites are dedicated to discussions on patterns. Compound patterns that represent a combination of patterns have even been discovered. While the benefits we've realized through this movement should not be questioned, the sheer number of patterns has created a situation in which it has become increasingly difficult to identify the most useful patterns for a particular context. In addition, it's common to find that many patterns have strikingly similar characteristics. When designing an application, I've found that simply determining which pattern to use can be as much of a struggl... (more)

Will Oracle Bid for HP?

"Larry Ellison is borderline bat-shit crazy on a good day," the analyst Rob Enderle is quoted as saying in a piece last week by Sam Gustin - a senior writer at DailyFinance, an AOL Finance & Money site. Enderle was prompted to utter this remark by speculation that perhaps the Oracle CEO is about to embark upon the acquisition of his life: of HP. "I think his bet is that he can damage HP enough that it drops in value and he can wander in with an offer," Enderle is quoted as having added. So is it possible that Ellison the Conqueror, CEO of Oracle Corporation since he founded the company in 1977, truly has the $90BN HP in the crosshairs of his acquisition rifle-sight? Can a $120BN company somehow buy and absorb a $90BN one? Well certainly he now has on board the exact right man to tackle the integration of such a purchase: none other than HP's own former CEO, Mark Hurd. A... (more)

View Aaater Suleman's @ThingsExpo sesion here The goal of any DevOps solution is to optimize multiple processes in an organization. And success does not necessarily require that in executing the strategy everything needs to be automated to produce an effective plan. Yet, it is important that processes are put in place to handle a necessary list of items.

Secrets of Java Serialization

Serialization in Java is an operation in which an object's internal state is translated into a stream of bytes. This binary stream or image of the object is created in an operating system-neutral network byte order. The image can be written to a disk, stored in memory, or sent over a network to a different operating system. This amazing feat requires little or no work on the part of the programmer. Just implement the serializable interface, which contains no methods, and call the writeObject() method on your object, and it's serialized! You can serialize an object to or from any I/O device that Java supports. The serializable interface doesn't contain any code or data; it's a marker interface. If a hierarchy of classes is to be serialized, each class in the hierarchy must implement the serializable interface. All objects that are in an object hierarchy, or "Web of ... (more)

Gen-it for Java 1.1 by Codagen

Test Environment Client/Server: Client: Dell Precision 410, 128MB RAM, 18GB disk drive, Windows NT Workstation 4.0 SP 5 Codagen Technologies Corporation 2075 University St., Suite 1020 Montreal, Quebec, Canada, H3A 2L1 Phone: 514 288-4802 Fax: 514 288-2446 www.codagen.com Pricing: Gen-it for Java $4,900/ Developer Batch-it for Java $295/ Developer In last month's issue of JDJ (Vol. 5 issue 6) I talked about the concept of using frameworks to automate the development of J2EE applications. Armed with this concept I took a look at Codagen Technologies' Gen-it for Java 1.1. Codagen's product is designed around the basic premise that much of the lower-level structural code within an application is highly repetitive. Routine tasks such as persisting objects into the database, managing locks and performing integrity checks can be easily generated from a template rather than buil... (more)

JBoss Teams with Librados

(July 24, 2003) - JBoss Group LLC has entered into a co-marketing agreement with Librados Inc., a provider of J2EE-standards based application integration software. Under the agreement, Librados has joined the JBoss Preferred Affiliates™ Program. Achieving more than 2 million downloads in 2002 alone, and on track to reach three million downloads in 2003. JBoss is the industry's fastest-growing Java application server. Through the partnership, using the Librados Enterprise Integration Component Server (EICS) and a family of pre-built JCA Adapters, Java developers can perform simple or complex application integration quickly and easily from the JBoss server or a Web server environment. Librados is reducing the cost of application integration by offering either royalty-free source code to independent software vendors, or extremely low-cost software to customers with it... (more)

LANSA middle-ware integration builds on MapForce

Here is a cool story about an Altova partner, who recently integrated the MapForce mapping and data transformation user interface into their product. LANSA is a development environment and suite of eBusiness solutions that organizations use to rapidly implement business systems that make effective use of new technologies. From its beginnings as a 4th generation language and repository-based development environment, LANSA has evolved to a family of products and solutions that support IBM iSeries (AS/400), Windows, UNIX and Linux platforms. LANSA Composer is built on top of LANSA Integrator, the company’s integration toolkit that offers bi-directional data integration through XML, SOAP, and Java services, on IBM System i and other middle-ware platforms. At its core, LANSA Composer utilizes the MapForce application as its transformation component: For more details, se... (more)

Improving performance of Java applications

During many implementation of high performance java applications, I found that the following strategies lead to be better performaning java apps -- especially better performing server apps. Limit the number objects instanciations. This might actually be difficult to do, however with the right design and approach tremendous saving are possible. Object pools is one way to go, but may not be applicable in every situation.Avoid or improve object serialization if possible. Object serialization (accross networks) happens to be very slow. It offers ease of use, but you pay in performance. Analyze the classes that are serialized and make sure only required attributes are serialized. Hashtables and complex structures are the biggest hit.Analyze and optimize string related operations -- especially concatentations, string buffer extensions are usually expensive.More threads do...

Indian Market finally opening up for Virtualization?, Gartner believes so

Naveen Mishra, Senior Analyst-Servers of Gartner finds that the market size is very small at this point in time, but the growth in the coming months and years will be rapid. While there is no sequential pattern observed in the adoption of virtualization-no pattern exists for server, storage, desktop, application or other infrastructure virtualization-a close observation shows that it is primarily servers that have caught up and storage virtualization is witnessed in the datacentre environment in the Unix space. However, the emerging trend is x86 server virtualization, which most companies including Sun Microsystems, IBM, HP, VMWare, Microsoft, Citrix etc., are driving consciously with their products and solutions. The virtualization scenario is currently purely need-based and is a priority area for CIOs for areas where it proves itself with benefits. For instance, ... (more)
