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.

Mainframe News Out There

Mainframe news out there – October 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:

Linux is Linux but Even More on IBM LinuxONE

Very interesting article by Stephen D. Bartlett in a recent edition of the Clipper Group’s online publication: “Linux is Linux but Even More on IBM LinuxONE”.  He gives as a very thorough look at IBM’s new LinuxONE Emperor II mainframe system – a Linux-only version of IBM’s new z14 hardware platform.  LinuxONE Emperor II offers capabilities that no other platform can match— like being able to give good response times at up to 100% utilization, etc. It is the world’s premier Linux system for highly secured data serving and analytics, engineered from top to bottom for security, availability, performance, and scale.

Blockchain technology and the Mainframe

How to deal with Blockchain in a mainframe environment.

Blockchain technology – if you were to believe in some of the hype – could change the world as we know it…

Realistically however – and in the right circumstances – Blockchain oriented approaches to effectively dis-intermediating existing business processes from the likes of centralized repositories, ESCROW account providers and similar – could provide immense opportunities for firms to become more efficient and cost effective.

Augmented Everything: How a CIO can make workers smarter, stronger, more aware

Much has been written recently about the emergence of Artificial Intelligence and robotics technology, and about how these technologies will destroy jobs and wreck society.

Someday, maybe. But today and for the next few years—the planning horizon of CIOs rather than academics—the reality is far different and far brighter: jobs will be enriched and the workers doing them will do them in new ways, at least for firms whose CIOs understand what’s happening.

Mainframe Development Must be the Focus, Not the Brunt, of a Digital Transformation

In a world of extreme and unpredictable change, agility is imperative. That’s why large enterprises have rightfully invested in all kinds of agility-enhancing capabilities—from hybrid cloud to DevOps.

Unfortunately, any improvement not made at the constraint is an illusion. So, at this point, many IT leaders are wasting their precious time and resources on making already-pretty-agile cloud/VMware/Java environments incrementally more agile—instead of focusing on their primary agility constraint: the mainframe.

Real-Time Reconciliation: z14 and the Holy Grail

In July 2017, IBM unveiled the z14, latest in its family of z-System mainframes. Capable of running over 12 billion encrypted transactions per day, the fastest commercial mainframe in the world opens up new horizons in every field of computer processing. This incredible speed brings the finance industry in particular close to a key goal dating all the way back to the rise of computer-assisted banking as the z14 is the first mainframe capable of real-time reconciliation. The holy grail of banking functions, real-time reconciliation represents an exponential leap forward in encryption, security, and analytics for the worldwide financial market.

How to Survive on a Frozen Mainframe Budget and Grow It

Interesting article by Steven A. Menges on the enterprisesystemsmedia online publication: How to Survive on a Frozen Mainframe Budget and Grow It.  “Many organizations are freezing mainframe budgets, not considering the spike in transactions and increasingly demanding service level agreements. Additional mainframe transactions aren’t driving more revenue; the same end users are just using different—and more—available resources and service channels. For example, globally there is a higher number of banking transactions, but people aren’t necessarily keeping more money in banks. With brick and mortar locations, ATMs and mobile apps, consumers are just doing more frequent transactions, using more computing power…”

Don’t Believe the Myth-information about the Mainframe: Part 2

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

Mainframes are Expensive?

Think that mainframes are expensive?  That depends on what you’re looking at.

If you are looking at acquisition hardware costs, certainly a single mainframe costs more than a single server or even several servers.  But, you would certainly need more individual servers to match the compute capability of a mainframe.  Add to that the idea that software and labor costs for servers grows linearly – the more servers you add, the more software licenses and the more system administrators are needed.  And yet, the mainframe delivers higher utilization, lower overheads, and the lowest total cost-per-user of any platform.  When all cost factors are considered fairly, the mainframe is usually the lowest cost alternative.

3 Important I/O Features Coming with the IBM z14

17 July 2017 marked the IBM announcement of the latest IBM mainframe: the IBM z14.  Congratulations to the IBM Z team on a successful launch of what looks to be yet another in a long and distinguished history of superb enterprise computing platforms.  Similar to the z13 launch in 2015, the z14 features several new, impressive I/O features and functionality that will provide tremendous business and technical value to IBM Z clients.  In the remainder of this blog post, I’ll discuss the highlights of what I view to be the three most important:  RoCE Express2, FICON Express 16S+, and zHyperlink Express.

Special engines that save cost on the Mainframe!

Do you know that mainframe systems have several kinds of engines (i.e., processors) not just a Central Processor (CP)?  Early mainframes had only one processor – the Central Processing Unit (CPU).  As the mainframe industry evolved over the decades, today’s systems have a Central Processor Complex (CPC) consisting of several different processor types.  Each processor type is used for a specific purpose.  Technically, all processors are the same out of the box, but are configured as specific engine types during installation, or at any time later by IBM.  Unlike CPs, which can be configured to run at lower speeds for software cost reasons, specialty processors usually run at full speed.
