• Untangling Legacy Spaghetti Code To Cook Up Microservices

  August 12, 2024 Michel Mouchon

  At this point in the history of programming, everyone pretty much knows what microservices are and everybody is more than acquainted with the legacy code – and often monolithic code – that has been created over decades by countless programmers who have evolved corporate applications to fit new conditions and new demands.

  It is often called spaghetti code, and for good reason. The code is often a tangled mess of business logic and data – presumably the data is the meatballs and the user interface is the sauce in this metaphor. (It is important to not take a metaphor too …

• IBM Banking on Merlin 2.0 to Goose Modern Development on IBM i

  June 19, 2024 Alex Woodie

  IBM last week shipped most of the new stuff unveiled in the Spring Technology Refreshes, which includes Merlin 2.0, the Web-based application development and modernization environment for IBM i. Big Blue is betting that the new and improved offering will encourage IBM i shops to (finally) begin their journey toward truly modern coding techniques.

  Friday, June 14 marked the start of general availability for the majority of the features IBM is including in IBM i 7.5 TR4 and IBM i 7.4 TR10, which it announced on May 8. The version 2.0 release of Merlin – whose official IBM name …

• ARCAD Breaks Up Monolithic Code With New Transformer Tool

  June 3, 2024 Alex Woodie

  There are many different aspects to application modernization: moving from 5250 greenscreens to Web interfaces, adopting the SQL database engine, and using DevOps techniques. Another part of modernization is breaking up monolithic codebases into smaller, more manageable chunks that can be more readily integrated using APIs and Web services, and that’s the goal of a new version of its Transformer product line launched recently by ARCAD Software.

  ARCAD Software already offers several capabilities under its Transformer brand, including Transformer RPG for converting fixed-format RPG to free-format RPG; Transformer DB for converting DDS files to modern DDL tables; Transformer Field for …

• DevOps Means Using The Tools You Already Have Better

  April 24, 2024 Jeff Tickner

  In this world, there are always more than two ways to skin a cat, but the best way to skin any cat is the way you already know how to do it.

  The same is true of application development from within a DevOps toolchain. When modernizing development processes on IBM i, the most efficient thing to do, always, is to make use of enterprise tools already in place within the organization and integrate these into a cohesive IBM i workflow that shepherds code from idea to production all along the way.

  It may seem obvious to say so, but trust …

• Hybrid Release Management Means Creating An Application Schema

  February 14, 2024 Marc Dallas

  In a hybrid computing world, no application is an island and similarly no system running those applications and the databases underpinning those applications can be an island, either. And yet, many IBM i shops still behave as if they can be islands when it comes to application release management.

  Despite this, based on our own experience and the anecdotal evidence we gather from IBM i shops like yours, there is a clear separation between release deployment in the IBM i world and the “other” release deployments in the enterprise. We need to talk about this.

  First of all, application deployment …

• 2024 IBM i Predictions, Part Deux

  January 22, 2024 Alex Woodie

  How will 2024 unfold? Nobody knows the answer to that. But that’s not stopping members of the IBM i community from taking some swings. It’s not only a good Bayesian exercise to think through the probabilities of what may occur, but it’s often a bit of fun, too.

  Our second batch of 2024 predictions starts with IBM distinguished engineer Steve Will, who, as the IBM i chief technology officer and IBM i chief architect, doesn’t need to guess where the platform is going, since he’s literally leading the creation of it. Instead, his prediction focuses on the community.

  “2024 will …

• What the Latest ALL400s Survey Tells Us About the IBM i Community

  October 18, 2023 Alex Woodie

  What is the most popular development tool in the IBM i community? What technology exists in nearly every shop? What BI tools are in use? And what activities are sitting in the IT backlog’s of IBM i shops? These are some of the questions that ALL400s answered with the latest edition of its IBM i community survey.

  You may have heard about ALL400s as the comprehensive list of IBM i customers around the world. John Rockwell, the Florida man behind ALL400s, does his best to keep the list as updated as possible.

  In addition to the list, Rockwell has put …

• Take A Progressive Approach To DevOps

  October 16, 2023 Jeff Tickner

  As Gene Amdahl, the chief architect of the IBM System/360 mainframe, correctly observed and what was subsequently codified as Amdahl’s Law, any kind of system that implements any kind of process is only as fast as its slowest component. What is true of bottlenecks in human processes is equally true in systems design and also in that overlapping area known as DevOps – the confluence of application development and system operations.

  If you can only be as fast as your slowest bottleneck, the converse is also true that you can speed up overall throughput of a workflow or a …

• The First Step In DevOps Is Not Tools, But Culture Change

  September 25, 2023 Andrew Clark

  The combination and automation of application development and IT operations, commonly known as DevOps, is itself like the processes it automates – it is a process of continual change through iteration and improvement. And so, like most things in life (other than vacation, maybe), it is a journey – not a destination.

  When people think about a DevOps roadmap journey, they are typically thinking about putting in some kind of DevOps tooling like git or Jenkins; this is really not the place to start – the first step on the DevOps roadmap, for most companies, is actually a culture change. …

• ARCAD’s Deal with IBM for DevOps In Merlin Is Exclusive

  September 20, 2023 Alex Woodie

  When IBM launched Merlin in 2022, it touted the browser-based environment as a new way to deliver functionality to the IBM i installed base and potentially to distribute third-party solutions. But right now, the only third-party vendor IBM is working with when it comes to Merlin is ARCAD Software, which has exclusive rights to supply the DevOps components within Merlin, according to executives with both companies.

  IBM introduced Merlin with great fanfare in May 2022 as a potentially transformative technology. Not only was Merlin the first browser-based integrated development environment (IDE) from IBM, providing an alternative to the powerful but …
