We were only just beginning to get our heads around Hadoop and Big Data in general when we find everyone is starting to talk about Big Data 2.0 – and it’s bigger, faster, and cleverer!
Hadoop, as I’m sure you know, is an open source project, and it’s available from companies like IBM, Hortonworks, Cloudera, and MapR. It provides a storage and retrieval method (HDFS – Hadoop Distributed File System) that can knock the socks off older, more expensive storage options on databases using SAN or NAS. It also means that more data can be stored. And that means not just human-keyed data, but data from the information of things (point of sales machines, sensors, cameras, etc) as well as social media. It’s an OCD sufferer’s dream come true. No need to delete (throw away) anything. But with all the data, it becomes important to find some way to ‘mine’ it – to derive information from the data that can be commercially useful. And that’s what’s happening, deeper and richer sets of results are being derived from the data that are beneficial to organizations.
With Version 2 of Hadoop, everything is faster. Data is processed at amazing speeds in-memory. The analysis is taking place at speed on terabytes of data. It also allows decisions to be made at speeds unavailable to humans. Research shows that algorithms with as many six variables out-perform human experts in most situations. This was tested on experts predicting the price of wine in future years and stock marketeers. So now, Big Data 2.0 means better decisions can be made at incredible speed.
It’s also possible for machines to learn using these techniques – such as the Google classic of having software that can identify the presence of a cat in video footage and no-one being quite sure how it is doing it.
For mainframe sites, Hadoop isn’t just some distant dream. You don’t need a room full of Linux servers to make it work – in fact that’s the clue to the solution. Much of this works very nicely on Linux on System z (or zLinux as many people still think of it). And once the data is on a mainframe, it becomes very easy to copy parts of it to a z/OS partition for more work to be done on the data. Cognos BI runs on the zLinux partition, so the first level of information extraction can be performed using that Business Intelligence tool. Software vendors are coming to market with products that run on the mainframe. BMC has extended its Control-M automated mainframe job scheduler with Control-M for Hadoop. Syncsort has Hadoop Connectivity. Compuware has extended its Application Performance Management (APM) software with Compuware APM for Big Data. And Informatica PowerExchange for Hadoop provides connectivity to the Hadoop Distributed File System (HDFS).
So what’s it like on the ground and away from the PowerPoint slides? At the moment, my experience is that really big companies – Google, Amazon, Facebook, and similar are pushing the envelope with Big Data. But it seems that many large organizations aren’t strongly embracing the new technology. Do banks, insurance companies, and airlines – the main users of mainframes – see a need for Big Data? Seemingly not – or not yet. Perhaps they are waiting for money to be spent and mistakes to be made before they adopt best practice and reap the benefits. Perhaps they are waiting for Big Data V3?
Big Data is definitely here to stay and those companies that could benefit from its adoption will gain a huge commercial advantage when they do.

Vivat mainframe
“Vivat Rex” is what the populace was meant to shout when a new king of England was crowned. It means “long live the king”. I think that we’ve been able to shout, “long live the mainframe” for a long time now, and recent announcements mean that we can continue to do so.
Mainframes, and I don’t need to tell you this, have been around for a long time now and have faced and overcome all the technical and business challenges that have been thrown at them in that time. And older mainframers can seem somewhat jaundiced when their younger colleagues get over-enthusiastic about some new technology.
We’ve looked at client-server technology and thought how similar it is to dumb terminals logging onto a mainframe. We’ve looked at cloud computing and thought how similar that is to terminals connecting to a mainframe in a different part of the world. But there’s much more to the mainframe than a simple ‘seen it, done it’ attitude. The mainframe is also able to absorb new technologies and make them its own.
We’ve looked recently at Hadoop – there are distributions from Hortonworks, Cloudera, Apache, and IBM (and many others). But you can run Big Data on your mainframe, and a number of mainframe software vendors have recently produced software that connects to Big Data from z/OS. It’s becoming integrated. So long live the mainframe with Big Data.
We’ve also, in this blog, looked at ways that BYOD – personal devices – can be used to access mainframe data, usually through browsers. And many of IBM’s younger presenters at GSE recently were talking about more Windows-like interfaces to mainframe information. Think of it – it’s like 1970 all over again – mainframes in the hands of 20-year-olds! So long live the mainframe with youthful staff and modern-looking interfaces.
We know there are other computing platforms out there, and IBM over the past few years has produced hybrid hardware that contains a mainframe and blades for running these other platforms. This summer’s zBC12 (Business Class) followed last year’s announcement of the zEC12 (Enterprise Class). And 2011 saw the z114, and 2010 gave us the z196. So long live the mainframe and its ability to embrace other platforms. (And I haven’t even mentioned how successfully you can run Linux on a mainframe.)
And thinking about mainframes embracing other technologies, CA has just announced the general availability of technology designed, they say, to help customers drive down the cost of storing data processed on IBM System z by backing up the data and archiving it to the cloud.
What that means is by using CA Cloud Storage for System z and the Riverbed Whitewater appliance, customers can back up System z storage data to Amazon Simple Storage Service (Amazon S3), a storage infrastructure designed for mission-critical and primary data storage, or to Amazon Glacier, an extremely low-cost storage service for which retrieval times of several hours are suitable. Both services are highly secure and scalable and designed to be durable. In addition, disaster recovery readiness is improved and AWS cloud storage is accessed without changing the existing back-up infrastructure.
So, yet again, we can say, long live the mainframe for the way it’s embracing cloud computing.
As a side note: Amazon has Amazon Elastic MapReduce (EMR), which uses Hadoop to provide Web services.
IBM has taken over StoredIQ, Star Analytics, and The Now Factory for Big Data Analytics or Business Analytics. And it took over SoftLayer Technologies for its cloud computing infrastructure. It’s making sure it has its hands on the tools and the people who are developing these newer technologies.
My conclusion is that there are new problems that need to be solved. And there are new technologies available to solve them. But so often those exciting new things are very similar to things that we mainframers have dealt with before. And where they seem different, mainframe environments are able to work with them and bring them into the fold.
There’s really no danger that mainframes are going away anytime soon. So, we’re very safe in saying, “vivat mainframe”.
