RZKH’s hosting solutions are primarily aimed at programmers who want anything from a small hosted development playground to a big redundant environment on the newest IBM hardware.

Overview

RZKH

Rechenzentrum Kreuznach (RZKH) was founded in 2001 by Holger Scherer, a renowned IBM System i and AS/400 expert and regular community speaker. The company’s data center moved to Rhineland-Palatinate in 2007, and then to a 1960s era German nuclear fallout shelter in 2009.

RZKH specializes in hosting, programming and consulting for IBM AS/400 and iSeries IBM hardware.

The RZKH website supports the German and English languages.

Features and Ease of Use

RZKH’s hosting plans are designed to suit a wide variety of users… as long as those users are IBM aficionados. To give you an idea of how targeted these plans are, I can tell you that the company promises to help you with hosting “even if you need to compile BASIC on V3R2.”

The company’s target customs are:

  • Individual developers doing IBM ‘i’ programming
  • Globally distributed development teams that want to work with shared data and programs
  • Corporate customers who need to copy their production environments for development or testing purposes
  • Corporate customers who don’t want to manage their own production environments
  • Former IBM AS/400 users who need to keep data/programs online for auditing purposes

Some unique features of RZKH’s hosting plans include access to (S)FTP/SCP servers, SAN-based RAID 6 disks, dynamic CPU management, and dedicated VPN setup (to be negotiated).

In addition to shared hosting for single or group accounts, RZKH also offers dedicated partitions/hardware to host your own operating system.

Pricing and Support

RZKH’s business price list suggests that its plans are competitively priced. However, every hosting solution is quoted individually based on the customer’s exact requirements in terms of:

  • OS version
  • CPU power
  • Disk and main storage
  • Planned period of use (from one month up to decades)
  • Data backups
  • Service level
  • Coding requirements and user support

You can call the company, or reach out via email or email-based ticket system. No business hours are stated, but it’s almost certainly not 24/7 unless this is specified in your bespoke SLA. Unfortunately, my exploratory email went unanswered.

The self-help resources are not much help at all. There is an empty blog, a software and tools page describing only the esoteric FB400 backup system, and a slightly more helpful list of useful links:

Bottom line on RZKH

If you need hosting for your particular IBM programming requirements, you might find that RZKH is uniquely positioned to help you. For everyone else, this is probably not the host you’re looking for.

Pros

  • 18+ years of experience in IBM ‘i’ and AS/400 hosting
  • Customized pricing for customers’ exact requirements
  • Safe data center (in a former nuclear fallout shelter)
  • Easy migration between plans

Cons

  • No 24/7 live chat
  • IBM-only hosting

If I was looking for a hosted IBM ‘i’ programming environment, I’d look at RZKH
