• Monoliths, Microservices, and IBM i Modernization: Part 2

  October 14, 2019 Alex Woodie

  Microservices are the future, right? After reading part one of this series, you can be excused for thinking that. Breaking up applications into smaller components brings clear benefits to both the development and operations staff, and clearly is an architectural approach that has a lot of momentum. But it turns out there might be practical limits to how far the microservices approach can take us.

  “Loosely coupled, yet tightly integrated.” That phrase became something of a running joke at an Infor conference attended by this reporter several years ago. The company at the time was betting heavily on its ION …

• Need Help Approving A Modernization Project? Try A Business-Led Approach

  October 14, 2019 Ajay Gomez

  Getting momentum and buy-in for a modernization project can be tough. I’ve lived through this and fought the battle many times. What makes it difficult is that the problem is not obvious and needs to be explained to people outside of IT. For example, it’s not obvious to a business leader that RPG II code should be modernized to RPG ILE. In fact, if we were to modernize the underlying code without telling them, they wouldn’t notice a difference. The business doesn’t see the effects of modernization unless it’s UI modernization, which is why it’s tough to get buy-in.

  Interestingly …

• IBM i 7.3 And 7.4 Get Their Autumn Tech Refreshes

  October 9, 2019 Timothy Prickett Morgan

  Big Blue is hosting its IBM Systems Technical University this week, and used the occasion to quietly launch the Technology Refreshes, or TRs as they are known, for IBM i releases 7.3 and 7.4. If you were running around the Venetian Hotel, you could probably stitch together the extent of the updates to the platform, and to be honest, we are still trying to get all of the details, which were not available as we went to press.

  We will tell you what we know now, and then circle back and drill down into the details as appropriate.

  First of …

• Sometimes Even DIYers Need A Little Help

  October 7, 2019 Timothy Prickett Morgan

  If there ever was a crowd that liked to do it themselves, it is the IBM midrange. Well, probably more like half to two-thirds of the IBM midrange. But you know what I mean.

  These companies started programming way back in the 1970s with one of Big Blue’s System/3 or System 32, or System/34 machines, and moved on to the System/38 or the System/36. The former launched in 1978, a decade after the System/3 that started it all in Rochester, Minnesota, and the latter came out in 1983, five years before the AS/400. The machines had sophisticated batch and interactive …

• Monoliths, Microservices, And IBM i Modernization: Part 1

  October 7, 2019 Alex Woodie

  What’s the best approach for application modernization: Maintain the monolithic architecture, or break it into individual microservices? This is an important question, especially for IBM i shops that are looking to take their considerable investment in encoded business logic to the next level.

  At first blush, the answer seems obvious: Monolithic architectures are bad, and microservices are good. Monolithic architectures, which are still quite prevalent in the IBM i world, proliferated from the 1970s well to the 2000s thanks in part to the popularity of packaged ERP suites that automated a multitude of processes and also to the programming inclinations …

• Midrange Dynamics Dives Into REST With Acquisition

  October 2, 2019 Alex Woodie

  Change management specialist Midrange Dynamics this month announced that it has acquired Rest4i, the UK-based developer of a native IBM i framework for integrating RPG and SQL applications with REST-based APIs. The move positions Midrange Dynamics as a player in the rapidly evolving world of microservices.

  Rest4i was founded several years ago by Stuart Milligan, who headed up DB2 database modernization firm Databorough before selling it to Fresche Solutions (then Fresche Legacy) back in 2013. Milligan foresaw the coming wave of microservices and developed software to “turn the IBM i into a complete REST API server and the RPG developers …

• ARCAD Unveils GUI Modernization Tool

  September 25, 2019 Alex Woodie

  ARCAD Software is getting deeper into the application modernization business with the launch of iNow, a new tool designed to help IBM i users create compelling graphical user interfaces (GUI) that run across Windows, Web, and mobile form factors. The new offering, which is based on Microsoft .NET and utilizes Remote Desktop Protocol (RDP) technology, is being sold as part of a new suite called ARCAD for IBM i Modernization.

  IBM i shops have been adapting their applications to Windows interfaces for the better part of 30 years, to the Web for about 20 years, and to mobile interfaces for …

• Guru: Enumerated Data Types In RPG

  September 16, 2019 Ted Holt

  IT has changed a lot since I entered the field several decades ago, but some things have not changed. I would read in those early days that COBOL was dead, and I read the same thing now. Yet COBOL is 60 years old and still going strong. Back then I heard RPG criticized as “Real Poor Garbage”. These days I hear it scorned as “legacy”, which I assume is supposed to mean the same thing. Yet today’s RPG is better than any of its predecessors for business programming.

  RPG supposedly does not have the features of modern languages. Maybe not, …

• PTC Completes Database Support In Implementer

  September 11, 2019 Alex Woodie

  As a change management tool, PTC’s Implementer is well-regarded among IBM i users for its ability to track development tasks and smooth out the promotion process. While the product has mostly been used to track source code in programming languages like RPG and Java, customers have increasingly been putting business logic into Db2 for i. With the recent launch of Implementer 12.3, PTC has wrapped up planned enhancements for the database.

  PTC‘s Implementer provides a full range of capabilities for managing development processes for IBM i shops. The software works closely with IBM‘s Rational Developer for i (RDi) …

• Fresche Hires Database Modernization Expert

  September 11, 2019 Alex Woodie

  IBM i database modernization expert Birgitta Hauser has a new software house to call home following her hiring at Fresche Solutions. The new gig marks the start of a new era in the German’s 20-year career on the IBM i, and adds to Fresche’s growing arsenal of midrange talent.

  IBM i shops around the world are under pressure to either modernize their systems or migrate to something newer. While IBM i applications largely do what they were designed to do, the requirements have changed, and the siren call of digital transformation and big data analytics is too hard for …
