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.

Guru: Move Objects with Access Client Solutions

October 14, 2019 Dawn May

Sending objects from one IBM i partition to another is a common task. Access Client Solutions’ IFS task makes it simple to copy or send objects. The IFS task was introduced in ACS in July 2016, so this is not a new development, but it may not be widely known.

Perhaps you need to send a save file to another IBM i partition. There are several ways to do this. FTP and Secure FTP are often used, but using FTP to transfer IBM i objects involves all sorts of complications. The IBM i Knowledge Center dedicates an entire section on …

An 11-Core Power9 Makes The Rounds, And Other Hardware Enhancements

October 14, 2019 Timothy Prickett Morgan

Those of us who go way back in the IBM midrange are used to rhythm in hardware announcements. In the early days, there were several announcements per year as new processors were rolled out across the product line and new peripherals for various kinds of storage and networking were rolled out. The pace was brisk back in the day, with nearly annual processor upgrades and associated updates to systems.

These days, systems are really updated every three years or so, but still, there is the vestigial spring/fall announcement cadence when Big Blue now does Technology Refreshes for the IBM i …

Systems Software Stack Tweaked For Power Systems

October 14, 2019 Timothy Prickett Morgan

As part of the October Power Systems announcements, IBM has made some minor tweaks to the systems software stack that runs underneath IBM i, AIX, and Linux on its Power-based systems.

In announcement letter 219-451, IBM reveals enhancements to its PowerVM server virtualization hypervisor, the PowerVC implementation of the OpenStack cloud controller (which presumably has a pretty short life now that IBM owns Red Hat), and its Virtual HMC (vHMC) hardware management console for Power iron.

The details are a bit thin, but IBM has made improvements with PowerVM V3.1.1 so Live Partition Mobility live migration of logical partitions …
