The IBM Z is IBM's new mainframe, which can handle 12 billion encrypted transactions a day and will be part of blockchain cloud centers.

The general idea is that IBM Z will encrypt all data all the time and reduce the attack surface for enterprises about 92 percent.

At the heart of the new system is an encryption engine that will encrypt data associated with any application, cloud service or database.

IBM said it co-designed the IBM Z with 150 clients including security experts and chief security officers.

Big Blue also said it plans to build six IBM Cloud Blockchain data centers with IBM Z as the encryption engine. Those IBM Cloud Blockchain data centers launched in New York, London, Frankfurt, Sao Paolo, Tokyo and Toronto to cater to the financial services sector.

The pervasive encryption approach includes:

• Data is encrypted at rest and in flight wherever it resides. In addition, data can be encrypted in bulk given improvements in the silicon dedicated to the cryptographic algorithms.
• IBM Z protects millions of encryption keys with tamper responding hardware that self destructs at any sign of intrusion.
  Encrypted application programming interfaces so developers can build applications and services.

IBM unveiled three container pricing models. Pricing for new microservices and applications can be co-located based on quality of service requirements. Application development and test environments will be tripled so capacity can be raised without a license increase. And there's pricing model for payment systems, which is based on the volume of payments not capacity.

These new pricing models will be available by the end of the year for z/OS V2.2 and z/OS V2.3.

IBM Z will be able to support 12 billion encrypted transactions a day, two million Docker containers and 1,000 concurrent NoSQL databases via three times the memory of the z13 and 3x faster I/O and transaction processing.
