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.

Q: Meltdown, Spectre (and new variants) – how best to cope?

A: Become a Grandmaster at Whack-a-mole!

“…used with reference to a situation in which attempts to solve a problem are piecemeal or superficial, resulting only in temporary or minor improvement…”

Much (very much!) has been written regarding the security threats posed by the discovery of system processors being exposed to the Spectre and Meltdown vulnerabilities.  And as if these vulnerabilities weren’t already serious enough a quick Google search yields headlines like: “Meltdown-Spectre flaws: We’ve found new attack variants, say researchers – Intel and AMD may need to revisit their microcode fixes for Meltdown and Spectre.”

Blockchain technology – the hype versus the reality

(Forget about the Drugs and Rock & Roll… it’s all about the SECS.)

Blockchain technology could change the world as we know it, or so the hype would have us believe.  Is blockchain technology really all that it’s hyped up to be?  Let’s compare the traditional centralized technology approach with the new kid on the block(chain), FinTech Distributed Ledger Technology (DLT) aka Decentralized database technology.  To put things into a more balanced perspective, let’s focus on some basics – specifically, the SECS:  S (Security), E (Efficiency), C (Costs/Compliance), and S (Speed).

Security

Mainframers are starting to ask questions about security – and that’s a good thing

IT security crises are forever making business headlines. In 2017 it was the high profile ransomware attacks and huge data breaches such as Equifax. Barely a week into 2018 and we had the revelations surrounding the Meltdown and Spectre vulnerabilities affecting computer chips around the world.

Traditionally, the mainframe community has been a little smug about security, generally believing our platform to be immune from many of the risks faced in distributed environments. Isn’t that one reason why the big banks and credit card companies continue to rely on mainframes to process transactions?

Don’t Believe the Myth-information about the Mainframe: Part 3

In this series, Janet Sun explores and dispels numerous myths around the mainframe. Continued from Part 1 and Part 2.

What Do You Lose by Moving Off the Mainframe?

Efficiency

Typically, distributed servers support a single application workload.  How many business applications does a typical company run?  Inventory control, order entry, accounts payable, accounts receivable, HR, shipping, business intelligence, research and development (multiple projects).  How many servers would be necessary to support these applications?

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….

Don’t Believe the Myth-information about the Mainframe: Part 1

When I heard about the HuffPost article highlighting a video debunking the myths that Hollywood has been repeating about the mainframe, I was cautiously optimistic.  Unfortunately, the writer chose to use only one reference book, and focused on the negative points.

Cloud Expo Europe 2017

After the Expo – Are we seeing a major shift in tech?

So another year passes and with a myriad of interviews under our belts later, we broadcast live at the Cloud Expo Europe 2017. We had a great line up of guests including ITV, Google, LinkedIn, IBM, Fujitsu, as well as many others. However, this article is not about name-dropping who was on the show but more so for the general trend and theme. To note as a main topic of discussion was the IT concept “Blockchain”.

The Need for Speed: Four Reasons Why Data Virtualization is Replacing ETL

One of the challenges of working in the modern world is adjusting to a faster and faster speed of computing. Globalization and mobile technology mean instant communications and near-instantaneous reactions are the minimum benchmark a firm must meet to keep up. Luckily, the business world has the mainframe, the fastest and arguably one of the most powerful computer platforms available. Mainframes are more than capable of processing all the instantaneous interactions our digital-age business world requires, from communication across systems, to logging transactions, to performing analytics in real time.
