z13s: An Affordable IBM Mainframe For Encrypted Hybrid Clouds?
Recent encryption trends indicate that ~50% of organizations transfer sensitive or confidential data to the cloud, whether encrypted or not; growing to ~75% of organizations in the next year or so. The number of organizations with an enterprise wide encryption strategy has risen slowly to ~35%. Seemingly ~40% of data at rest in the cloud is unprotected! One must draw one’s own conclusions as to why cybersecurity attacks are increasing in number, with the inevitable consequence of business data exposure!
Historically the enterprise class business deployed the best available IT infrastructure for their available budget. Generally this generated a modus operandi of quantifying the cost of computing power (I.E. Cost per MIPS), where business chargeback scenarios were both scarce and simply measured. From a business viewpoint, arguably the best measure of business cost is transaction based, where these external facing transactions deliver business value, both in terms of financial and reputation attributes. With the current digital data explosion, driven by Mobile and Social interfaces, the number of business transactions increases significantly, year-on-year, while the security exposure for the associated business data has never been higher. What is the feasibility of deploying a single footprint computing platform that delivers industry leading security, capacity and performance, while fully interacting with Hybrid Cloud topologies for rapid and agile Application Development and delivery?
Recently IBM announced the z13s, their latest addition to the System z server family. Some 13 months following the release of the Enterprise Class z13, the z13s offers a granularity of capacity from 10 MSU (~100 MIPS) for the 2965-A01 IBM z13s Entry Model to 884 MSU for the 6 Engine 2965-z06 IBM z13s. From a System z MLC software TCO viewpoint, an annual cost of ~£150,000 (~$200,000) applies for a 10 MSU (~100 MIPS) system configured with z/OS, CICS, DB2, WebSphere (MQ), Programming Languages (I.E. COBOL, Java, et al) and a modicum of Systems Management software. Therefore over a 3 year period, the realm of possibility exists for a commercial business to leverage from today’s unrivalled RAS (Reliability, Availability and Security) attributes of the z13s server, for ~£500,000. Even this cost base could be further optimized with use of specialty engines (I.E. zIIP, IFL) and current MLC pricing regimes (I.E. zNALC, zCAP, et al).
IBM state the z13s is enabled and optimized for hybrid cloud environments and can help secure critical information and transactions better than before. Clearly the IT landscape is rapidly evolving, with an ever increasing requirement for secure and timely access to increasing amounts of digital data, primarily from mobile devices. This paradigm shift of data creation and access dictates that cybersecurity is a fundamental and mandatory requirement for each and every organization, where the System z server has always delivered the highest levels of security, currently certified at EAL5+ (Common Criteria Evaluation Assistance Level 5+).
Businesses need to be flexible, dynamic and agile, being mindful of TCO optimization. It was forever thus, Information Technology teams must embrace social and mobile trends and the challenges they create. This requires new insights and ways to integrate these trends into existing processes and IT infrastructures. Incorporating these new insights and opportunities into business processes and associated IT disciplines helps the business grow and be competitive, while reducing cost and increasing efficiencies. Leveraging from technologies such as the latest z13s server can assist organizations in reaching this enterprise class infrastructure, but a combination of IT infrastructure management best practice and leading-edge technology is required.
The z13s is designed for the toughest real-time business challenges. It provides significant scalability attributes in terms of memory, I/O and single footprint CPU power that responds instantaneously to business processing fluctuations. Therefore the z13s helps organizations meet mission critical Service Level Agreements (SLAs), with real-time delivery and analytical insight for ever increasing amounts of business data and information, delivering an advantage of more timely business decisions. The flagship IBM z/OS Operating System supports the z13s processor topology, optimized for scalability, cost saving, advanced compression capabilities, reliability, availability and scalability. Delivered with the unparalleled System z security attributes, the z13s provides best in class data protection for business users, customers and partners alike.
For those organizations that have never considered a System z Mainframe before, the z13s delivers an eminently affordable IT platform that delivers a compelling infrastructure for today’s hybrid cloud environments. From a dispassionate viewpoint, some cloud deployments (I.E. IaaS, PaaS) dictate the utilization of 3rd party server resources, which of course simplifies IT infrastructure management. However, it can also expose the business to scenarios beyond their control, whatever the uptime promise of the 3rd party supplier.
From a security viewpoint, the z13s server technology leverages from two cryptographic hardware features. Firstly, the Central Processor Assist for Cryptographic Function (CPACF) delivers cryptographic support for the Data Encryption Standard (DES), Triple DES (TDES), Advanced Encryption Standard (AES) data encryption/decryption and Secure Hash Algorithm (SHA). Secondly the Crypto Express5S (CEX5S) feature is packaged in a PCIe adapter card containing a Cryptographic Coprocessor Subsystem housed within a FIPS Level 4 physically secure enclosure (Security Module). CEX5S delivers secure cryptographic functions for banking, finance and high data security environments. The primary customer application within the CEX5S card is CCA (Common Cryptographic Architecture). From a usability viewpoint, z13 cryptographic features support Format Preserving Encryption (FPE), for common user identity data strings such as Social Security Number (SSN), Personal Account Number (PAN), et al, with specific support for the Visa Format Preserving Encryption (VFPE) standard.
Since its inception, the IBM Mainframe has always delivered consistently low transaction response times, especially when a workload grows, sometimes peaking with an abnormally high requirement. The evolution of the z13 architecture safeguards this industry leading transaction response time is maintained, even when applying the highest levels of EAL5+ security. It was forever thus for the System z platform, where marketing statements are supported by the requisite performance benchmarks, in this case detailing the many scenarios for z13 Performance of Cryptographic Operations.
In conclusion, whether an existing IBM Mainframe user or not, the TCO and indeed TCA (Total Cost of Acquisition) attributes of the System z platform reduce year-on-year. Such a cost profile includes the System z platform of worthy consideration for each and every business, with a workload requirement of ~100 MIPS (~10 MSU) or more. Moreover, the notion of decommissioning an IBM Mainframe for the modernization of a legacy workload should be consigned to history forever more. Quite simply because the System z platform is open to all the rapid and agile Application Development and Deployment techniques available to Distributed Systems platforms.
