When Primary and Backup are called for!

 

Many years ago, when Margo and I frequented the highways of North America in our RV, we talked about buying a dog. For those who may have passed RVs in parking lots, you may have run across the decal telling everyone that the RV was unlocked and the keys were under the German Shephard. We had a colleague from our Tandem Computer days that bred German Shepherds and we thought that there would be nothing better than to own a pair of them. Back when I lived in Sydney I had a Shephard – Labrador mix and the family truly loved him, so the idea of owning a pair of Shepherds didn’t seem all that out of the ordinary. With tickets to California in our hands and plans to accommodate well advanced, it was only the voice of our family members warning us: with the dogs we do not get to play with our granddaughter and that led to a late cancellation of such a purchase.

It then should come as no surprise that at that time we had made the decision to call them Primary and Backup! I recalled this thwarted exercise as I stood in the service bay of our local Jaguar dealership. For many years there was a saying that went something like, “if you own a Jaguar, you better buy two to make sure you had one to drive!” Today however, nothing could be further from the truth as the Jaguars of this century have, for us at least, proved extremely reliable. The two were in the service bay as we dropped off the second Jaguar when picking up the first and what went through our minds was well, it all made sense didn’t it? Nothing wrong was there, when you consider the weather that crossed Colorado’s Rocky Mountains, in having Primary and Backup!

The April issue of NonStop Insider has hit the digital newsstands and can be read by following this link - https://www.nonstopinsider.com/editorials/issue-7-4-editorial/ It is a bumper issue to say the least, with articles from HPE folks across North America as well as Asia-Pacific. There are numerous commentaries on NonStop SQL, Security, including Ransomware, Platform Modernization and a return visit to the IDC grading of systems, ranking them by levels of availability. The premier level has always been Availability Level 4 and for quite some time, this level was shared only by NonStop and certain configurations of the IBM mainframe.

But of late, IDC has begun watering down the criteria to where now it is simply addressed with the following:

True fault tolerance through redundancy in hardware and software: This approach provides continuous data processing, even in the event of the failure of one hardware or software component. Because all data processing (i.e., support for a given application) occurs in a side by-side fashion, the failure of any single component in the system will not affect other sets of computing resources that also support that same application. As a result, computing can continue uninterrupted.

Spot the out for most vendors? Here you have it: “The failure of any single component in the system will not affect other sets of computing resources.” In other words, you may be down but no other application running at the time should be affected. So sad to hear you are only running one application! In a world where we so often hear of good enough being well, good enough and glitches happen all the time. If as yet you haven’t read my latest commentary on AL4 then check the article in the April issue of NonStop Insider - https://www.nonstopinsider.com/uncategorised/the-latest-on-fault-tolerance-hpe-is-a-key-player-in-the-al4-market-according-to-idc/

IBM released the Z16 last year to quite a fanfare, most of which centered on the mainframe now becoming available in rack-mounted form. Yes, more than a decade after NonStop embraced rack mounting, IBM considers their work as a breakthrough for the enterprise even as they recognize that in many ways they were late to the party.

But it isn’t just that NonStop has been available rack-mounted for such a long time as it is highlighting how little attention IBM is paying to capitalizing on the presence of the cloud; racking mainframes may be fun but that’s just a start, surely? And it isn’t until you address the presence of clouds, be they private or public, that you can truly call yourself modern. IDC may give a gold star to NonStop and the Mainframe but even then, the awarding of that star doesn’t suggest for a moment that the system being so honored is modern!

There is one other article in the April issue of NonStop Insider that is worth reading in full - https://www.nonstopinsider.com/uncategorised/what-comes-after-development-simplified-deployment-for-hpe-nonstop-applications/ It covers the two story lines of two most recent posts to the HPE Community Blog that focus on just how modern NonStop has become, whether it is from a development or deployment perspective. Both of these posts reference the many television episodes featuring home renovations where we have all become acquainted with what makes a home modern – open floorplan, clear sight lines, stainless steel appliances.

For a more comprehensive overview of both these posts on modernization of development and deployment as they appear in the HPE Community Blog, take a look at the latest issue of The Connection. Re-appearing in The Connection for the first time in decades is my column Real Time View. As noted in prior posts to this blog, Pyalla Technologies, LLC. is throwing its full support behind Connect and future posts to this blog will only touch on topics that might otherwise not find their way into NonStop community media.

Comparing today's IT deployments with how modern homes function can only go so far and yet the imagery is hard to ignore. “In many ways, IT development wants to leverage open technologies as much as possible even as they want connectivity to every corner of the enterprise along with the ease of movement that this entails, within the enterprise and beyond,” said HPE Mission Critical Systems Marketing Manager, Vikas Kapoor.

And now there will be the opportunity to develop applications for NonStop out of public clouds. For AWS users this is as simple as connecting to the Public Cloud Marketplace where you will find everything you need to develop an application that targets the NonStop platform. Look for support of other public cloud providers to follow shortly.

So here is the answer to the question that is almost certainly going to be asked. Again, isn’t good enough, good enough, but now, you can have it all – out of the box. Whether you develop in Java, C/C++ or Python, it’s all there in the public cloud for you to leverage. More importantly though is the ability to inherit the fault tolerance of NonStop without digging deep into its internals or becoming an expert in all things NonStop.

The flip side is that accepting good enough can be dangerous. It leads to a false sense of security anchored solely in the belief that it’s OK to be good enough as “we have always done it that way!” AL4 with meaningful and usable fault tolerance is at your fingertips and can be leveraged right out of the box. This remains an unheard of experience on platforms other than NonStop, so yes, good enough may be good enough for some, but why would you ever settle for second best?

This topic and much more will feature heavily in the upcoming regional user events, the most important event of all being the E-BITUG in Edinburgh Scotland, May 15 – 17. For the latest updates on this event, check out the E-BITUG web site - https://www.bitug.com/ebitug-2023. There will be a lot of product updates along with news from the participating vendors you may have missed, so plan accordingly. Looking ahead to future events in 2023 there will continue to be highlights of just how the NonStop technology, whether running on-prem or in the clouds is still significantly ahead of the pack. Or, as one NonStop product manager reminded me in a recent exchange, “if you are not aiming for the best you will eventually fall behind.”

What should not be missed is just how far NonStop systems have come from when it was all about those Primary and Backup use cases that dominated much earlier events. They still embody the effectiveness of the “special sauce” of NonStop that separates NonStop from all else.

We never did get those German Shepherds and saying we have tame Jaguars doesn’t really cut it. We no longer have the RV either, but then again, the thought of having primary and secondary processes behind the scenes supporting almost every financial transaction we perform assures us that as blasé as some may be about good enough, ultimately, good enough no longer cuts it when it comes to the deployment of today’s modern systems.

If it’s June then it’s time for HPE Discover 2021.

  For the NonStop community there has always been an annual event that proved hard to resist; with changing times these events are virtual – but can we anticipate change down the road? Just recently Margo and I chose to return home via US Highway 129. It may not ring any bells, but for those who prefer to call it the Tail of the Dragon – 318 curves in 11 miles – it represents the epitome of mountain excitement. For Margo and me, having now driven the tail in both directions, driving hard through all these turns never gets old. Business took us to Florida for an extended week of meetings that were mostly conversations. Not everything went to plan and we didn’t get to see some folks, but just to have an opportunity to hit the road and meet in person certainly made the 4,500 miles excursion worthwhile. The mere fact that we made touring in a roadster work for us and we were comfortable in doing so, well, that was a real trick with a car better suited to day trips. This is all just a p

The folly that was Tandem Computers and the path that led me to NonStop ...

With the arrival of 2018 I am celebrating thirty years of association with NonStop and before that, Tandem Computers. And yes, a lot has changed but the fundamentals are still very much intact! The arrival of 2018 has a lot of meaning for me, but perhaps nothing more significant than my journey with Tandem and later NonStop can be traced all the way back to 1988 – yes, some thirty years ago. But I am getting a little ahead of myself and there is much to tell before that eventful year came around. And a lot was happening well before 1988. For nearly ten years I had really enjoyed working with Nixdorf Computers and before that, with The Computer Software Company (TCSC) out of Richmond Virginia. It was back in 1979 that I first heard about Nixdorf’s interests in acquiring TCSC which they eventually did and in so doing, thrust me headlong into a turbulent period where I was barely at home – flying to meetings after meetings in Europe and the US. All those years ago there was

An era ends!

I have just spent a couple of days back on the old Tandem Computers Cupertino campus. Staying at a nearby hotel, this offered me an opportunity to take an early morning walk around the streets once so densely populated with Tandem Computers buildings – and it was kind of sad to see so many of them empty. It was also a little amusing to see many of them now adorned with Apple tombstone markers and with the Apple logo splashed liberally around. The photo at the top of this posting is of Tandem Way – the exit off Tantau Avenue that leads to what was once Jimmy’s headquarters building. I looked for the Tandem flag flying from the flagpole – but that one has been absent for many years now. When I arrived at Tandem in late ’88 I have just missed the “Billion Dollar Party” but everyone continued to talk about it. There was hardly an employee on the campus not wearing the black sweatshirt given to everyone at the party. And it wasn’t too long before the obelisk, with every employee’s signature
