We are very grateful as always to all those who have contributed this year by writing articles, taking part in our annual user survey, or updating their company profiles. In particular, I must thank the sponsors and advertisers, without whose support this Yearbook would not be possible.
2017 seems to be picking up where 2016 left off and there seems to be a spring in the step of the mainframe world. Vendors, who never claim business is a bit flat anyway, seem to have bigger smiles when they tell me that business has been good. And at user group meetings, sites seem to be trialling newer software and techniques, whereas before there had been a certain reluctance to try anything new.
On the downside, of course, the IT world has been reeling from ransomware and other cyber attacks. In June 2017 Wannacry locked computers and messages appeared demanding $300 in Bitcoins to regain access. We also heard in 2017 that Members of the British Parliament had had their e-mails hacked. Deloitte was hit by a cyberattack, which accessed e-mails, usernames, passwords, health information, and details from Deloittes clients. Equifax had 143 million customer account details, including names, social security numbers, drivers licences, and credit card numbers of around 200,000 people hacked. And the list goes on.
In July, IBM announced the new Z14 processor and we all started saying pervasive encryption. The new mainframe had more total system capacity compared to the z13; faster uniprocessor performance than the z13; 170 cores to configure (141 on z13); up to 32TB of available Redundant Array of Independent Memory (RAIM) real memory per server; 2x more on-chip cache per core, compared to z13; hardware accelerated encryption on every core with the Central Processor Assist for Cryptographic Function (CPACF) feature; new instructions in Single Instruction Multiple Data (SIMD) which are designed to give a performance boost for traditional workloads using COBOL and new applications like analytics; and much much more.
But what is pervasive encryption? It doesnt have an official definition, but generally means the ability to encrypt everything everywhere without interfering with the user experience. The new IBM Z14 mainframe can do real-time encryption of all mobile transactions up to 12 billion encrypted transactions per day. The new mainframe has an encryption engine, which gives a 7 times increase in cryptographic performance over the z13, with a 4 times increase in silicon dedicated to cryptographic algorithms. It protects encryption keys with so-called tamper responding hardware, which invalidates keys at any sign of meddling, and IBM says they can be safely restored later. This capability can be extended outside the Z14 to storage systems and servers in the cloud. A Secure Service Container is claimed to protect against insider threats from contractors and privileged users, providing automatic data and code encryption in-flight and at-rest, and tamper-

resistance during installation and runtime. The Z14 can pervasively encrypt data associated with any application, cloud service, or database all the time.
The new processor lifted IBMs spirits, as did its third quarter figures in October, which registered a strong recovery following a weak first half of the year. There was a 0.4 percent decline in revenue, to $19.15bn, and IBMs pro forma earnings per share rose 11 per cent to $3.30. In the third quarter, revenue from the strategic initiatives (cloud, analytics, mobile, social and security) rose 11 percent. Cloud now represents 20 percent of IBMs total revenue. Revenue from the mainframe business jumped 60 percent in the third quarter. The Z14 began shipping in mid-September.
IBM has been much less acquisitive in 2017, with only three companies. Firstly, in February it acquired Agile 3 Solutions for its Information security business. In May it acquired German-owned XCC (a division of TIMETOACT) for its collaboration software. And in October it acquired Australian Vivant Digital for its innovation consultancy business.
In terms of big software announcements, during the year, IBM announced CICS Transaction Server for z/OS Version 5.4. And the company also announced IMS 15.
2017 seems to have been the year when IBM changed case! Things that used to be capitalized no longer are, and things that werent capitalized are now. People still talk about System z, which changed its name to z Systems, but is now IBM Z (yes, thats a capital). Or what about DB2, or, as we should now call it, Db2? The b is now lowercase putting the emphasis on the data and not on the base.
2017 also saw hackathons becoming more mainstream and a way for large organizations to offer better service to their customers. Whereas much mainframe software is still developed using waterfall methodologies, where two years could elapse between the identification of requirements and an application being delivered and by then, the circumstances that led to the need for the software could be very different. For a hackathon to be successful, the existing technology needs to be commoditized and abstracted. APIs are the driver. And if the product thats created by the end of the hackathon doesnt work, then it can be treated as a learning experience for the people working on that project. For example Citibank runs Citi mobile challenges. These get people to look at different ways people can consume their banking services its a way to get the next big idea from people outside their company. And Ciitbank can then monetize the ideas. Blockchain is great for hackathons because it is digital and secure.
As well as pervasive encryption, other words or acronyms people in 2017 were starting to use in connection with mainframes include: Swagger, Bluemix, GitHub, Jenkins, blockchain, GDPR, SIEM, Enterprise Content Management (ECM), Destruction Of Service (DeOS) at
