Porting an Enterprise App to System Z – My Experience Pt.3

Part 3 of 4: The Bad

As I’ve explained in Part 1 Basics and Part 2 Good, I did a proof of concept port of an Enterprise Application from Amazon Web Services on x86 to Linux on System z in 2017. The good news was I got to the point I needed to, the bad news was it was more than difficult to get there.

Porting an Enterprise App to System Z – My Experience Pt.2

Part 2 of 4: The Good

I provided a simplistic overview of what I intended to port to Linux for System z in Part 1. The original application was built for x86 systems. As such, all binaries are built to run on x86 systems. The Docker containers that these applications run in are x86 binaries as well. So my job was to create the Linux for System z (aka S390X) binaries, with as little change as possible.

Porting an Enterprise App to System Z – My Experience

Part 1 of 4: The Basics

At the end of 2016 and lasting a few months into 2017, I completed a proof of concept port of a large Enterprise Application that had been running on the Amazon Web Service Cloud to Linux for System z. This was a Docker based application written in Java…so of course, it would be trivial to port. WRONG. While the application is in Java, it called many pieces of open source code. Much of that code hadn’t been ported to System z yet or wasn’t widely adopted. What I thought was a very simple exercise turned into a six month effort.

Demystifying Cloud for Mainframe Managers

The IBM 360 mainframe made its debut in April 1964. With the unprecedented ability to perform 229,000 calculations per second, it became the enterprise platform for transaction-heavy, critical applications. With the emergence in the mid-1980s of mid-range systems (such as SUN’s RISC processor) as well as PCs networked with servers, many thought the mainframe would go the way of the dinosaur. However, in the early 1990s IBM introduced the System/390 family with a groundbreaking computing capacity of 1,000 MIPS (million instructions per second). Since then mainframe computing capacity has increased by more than 30% year-over-year.

Bringing Machine Learning to Big Iron

In today’s data driven economies there is evermore pressure to drive financial returns and payback for IT investments, increasing the need for IT organizations to deliver both analytics and digital transformation with practical and meaningful business outcomes.

The need for instant services has increased exponentially due to ’consumer driven’ services such as Application Stores, Digital Music, Social Media, E-commerce, FinTech and even IoT. This consumerization of technology drives innovation within the enterprise to reach user expectations but the challenge, as always, is doing this in a highly available and secure manner.

Mainframe News Out There

Mainframe news out there – November 2017

Once a month we like to pick articles from other blogs that we feel are interesting enough to talk about on the Planet Mainframe blog. Here are this week’s picks:

The Engine of Digital Disruption in the API Economy

Very interesting article by Dr. Richard Gamblin in a recent edition of the Enterprise Executive online publication: “IBM Z Systems: The Engine of Digital Disruption in the API Economy”.  A common misperception is that mainframes are somehow irrelevant in the API economy; however, the reality is that they are surprisingly well placed to service the needs of the contemporary developer. Consider that organizations exploit IBM z Systems for its proven track record in high volume transaction processing….

Open Source on Steroids

The words “digital transformation” are on the lips of every person in technology and tech media, as well as many business leaders – from company CIOs and CTOs to technology to business line managers to writers in news publications and tech blogs.

At its core, a digital transformation is the enablement of technologies and workplaces tuned to today’s digital economy. The beating heart of this digital economy is the API, and is being followed now by emerging technologies like IoT (Internet of Things) and FinTech technologies like Blockchain.

3rd platform and the mainframe

The Third Platform and the Mainframe

The Third Platform is defined as the interdependencies between mobile computing, social media, cloud computing, and information/analytics (big data), and possibly the Internet of Things (IoT). Here is a nice rendering of the Third Platform model from Forbes.com. It shows our new concerns: Mobility, Analytics, and Cloud (SMAC-IT) at the top level on the “Third Platform,” our LAN/Internet and our Client/Server apps on the “Second Platform,” and the clunky old Mainframe on the “First Platform.” When talking about the First Platform, people say that we know how these systems worked and how they were used, as if it’s all in the distant past. And that’s a mistake.

Think before you click Hybrid Cloud Computing

Many of you may be thinking why on earth am I even suggesting this? Hybrid cloud computing offers flexibility, fault tolerance, subscription-based cost models, and much more. While that’s all true, it simply does not fit everyone’s business model. Let me explain.

zUniversity Munich Insights

The European version of the IBM zUniversity took place in Munich on June 13-17 this year and it was a first time for me and the rest of Insoft-Infotel team to attend such event. In all there were two Planet Mainframe members to attend this event, both having our exhibitor booth right next to each other. Let’s have a look at what went on during those five days.
