1. The Big Easy: Connecting The Dots On Big Blue’s AI Strategy For IBM i

   IBM has not yet formally announced the new AI products that it is building for IBM i. We know about Bob and the MCP server, but there is a lot more AI stuff coming to IBM i. IBM shared details of what is coming in closed sessions at POWERUp in New Orleans last week, but hints about where it is going and what is coming were there, if you knew where to look.

   IBM i, as we all know, is a business platform. It runs enterprise applications and it runs them extremely well. If you want to model a nuclear …

2. From Migration To Maturity: The Cloud Reality For IBM i Shops

   IBM i teams don’t need to be convinced that modernization matters. Modernization should acknowledge why IBM i continues to power critical business operations: its predictable performance, tightly integrated environment, and strong security – especially when properly managed. While cloud initiatives are often framed with the assumption that everything must move, that approach is rarely the most effective starting point for IBM i environments.

   As cloud adoption has matured, a more grounded perspective has emerged. The real shift isn’t about infrastructure –it’s about the operating model. Most challenges don’t stem from technical limitations, but from misaligned expectations around cost, security responsibilities, …

3. COMMON Dances To A Fresh New Tune In New Orleans

   This wasn’t the first COMMON conference held in New Orleans, but it may have been the best, considering where the IBM i platform is at this particular time and what happened down on the bayou last week.

   For starters, the four-day event attracted about 1,300 attendees, which is a solid increase from the 1,200 that attended last year’s conference in Anaheim, California. But here’s the kicker: About one-third of the COMMON POWERUp 2026 attendees were attending the conference for the first time. In other words, around 400 folks decided that IBM i education and community were important enough for them …

4. Eradani Touts Native Git Connection As AI Tools Spread

   Thanks to AI tools like Bob and Claude, IBM i shops are changing how they develop code. AI tools can crank out RPG much faster, but the quality is inherently suspect, which makes having a solid change management life cycle very important. It’s the perfect setup for the folks at Eradani, who say their IBM i change management tool’s native integration with Git provides the right capabilities at the right time.

   What makes Eradani’s approach to supporting Git with its Eradani DevOps offering is the lack of compromise. Instead of splicing Git support into an existing change management product, …

5. IBM i PTF Guide, Volume 28, Number 17

   We are in the middle of a house move right now, so the IBM i PTF Guide is running a little bit behind as we box and tape and lift and stack. In this week’s issue, we have two security vulnerabilities right off the bat.
