3 Agenda Motivation Be a target of services What is meant by Cloud Computing Statement of Direction What s next? Lets talk Summary 3

4 There is a WAR going on 5

5 There is a WAR going on Over YOUR Applications Over YOUR Application Developers Over YOUR Information Delivery Over YOUR Future 6

6 There is a WAR going on Over YOUR Applications Over YOUR Application Developers Over YOUR Information Delivery Over YOUR Future But You really need to pay attention to Cloud 7

7 CIO Goal: Innovate like a Startup New applications to customers quickly Embrace Digital Transformation Reduce costs Fast / Reliable / Secure Must be user centric Small companies winning because they are fast and agile 2016 IBM Corporation 8

8 Things in Your Way Lines of business view IT: The guys who say, NO! Are slow to respond Just a cost center IT is measured in outages not in contribution Politics/Religion Chargeback Machine dedicated to a project Moving to an image model doesn t help 2016 IBM Corporation 9

9 Cloud s Big Shift to API Economy Cloud focus is on agility and speed Cheapest possible infrastructure is secondary Don t need to develop everything internally Can link multiple services internally and externally Get apps out quicker Goal: Idea in the morning into production by evening Not having APIs in 2016 is like not having a website in IBM Corporation 10

10 APIs Rely on Web Technologies Loosely coupled systems Lightweight communication Easy to learn and use Almost 0 learning curve Language independent New programmers productive immediately Remove silos in development Pool developers rather than tie them to a product 2016 IBM Corporation 11

11 Common Myths Mainframes are expensive Reduce MIPS Get off the mainframe strategy Applications are black box and probably monolithic Mainframe is a one off Getting changes on the Mainframe takes too long x86 Linux is the defacto industry standard I just need a whole bunch of them Public Cloud can provide almost all that I need My x86 environment will work with it easily Public Cloud gives me what I want immediately Cloud is about managing everything from a single pane of glass Can t find Mainframe skills 2016 IBM Corporation 12

12 Organizations are exploiting the fundamental strengths of the mainframe today Transaction Processing Data Serving Mixed Workloads Operational Efficiency Trusted and Secure Computing Reliable, Available, Resilient Virtually Limitless Scale Data and Transaction Hub of Global Economy 68 for 6 Mainframes account for 68% of production workloads, but only 6% of IT spend 1 1 Source: Solitaire Interglobal

13 The mainframe is everywhere, making the world work better Mainframes process 30 billion business transactions per day Mainframes enable $6 trillion in card payments annually 80 percent of the world s corporate data resides or originates on mainframes 91 percent of CIOs said new customerfacing apps are accessing the mainframe

14 IBM z is positioned to enable the digital transformation Support next gen computing and consumption model Mobile Analytics Cloud Blockchain Execute with agility, leveraging strong, open ecosystems DevOps APIs Open Skills Deliver trusted, high performance, and resilient platforms Technology Systems Software Security

15 API s The Equalizer Your services are seen by other services as API s Nobody knows or cares what runs the API s They want API s that do what they need They want the most functional, highly available, highly scalable, secure, best performing API s Sounds a little like z/os ities doesn t it? IBM Corporation

16 z/os Perfect API Platform Provision new services quickly No need to bring up new servers everything in 1 OS Leverage existing investment New API interface on existing code More economical than rewriting Cost more to rewrite Rewrite introduces risk Rewrite will take time Tooling exists to help 2016 IBM Corporation 17

17 z/os Secure API Environment Can easily fit into an existing Security profile Leverage the inherent security in the hardware and software Increased auditability Can become the secure bastion for the whole enterprise 2016 IBM Corporation 18

22 Need to Move Now! Companies adopting services model will win Lack of movement will make IT irrelevant Lines of business are already going to cloud solutions instead of IT Stagnation, arrogance, hubris will kill 2016 IBM Corporation 23

24 Cloud Computing on z/os With z/os, we need to think about cloud just a bit differently.. Today in cloud environments on distributed servers, or even with Linux on z Systems, customers would provision a virtual machine with an instance of an operating system to run a single workload. To deploy another workload would mean another virtual machine with another instance of the operating system. However, in the context of z/os, this methodology goes against everything we have come to know and expect about z/os. On z/os, you have the ability to run multiple disparate workloads with different service levels for those hosted workloads with isolation or multitenancy. Hence our approach for cloud on z/os is not focusing on the provisioning of operating system instances, but rather the ability to provision multiple workloads in a single z/os instance. We make the assumption that the z/os operating system is already part of the infrastructure and does not need to be instantiated to deploy a workload in a production environment. Provisioning a new instance of a the z/os operating system in a new LPAR is an important dev/test requirement, but out of scope of this work IBM Corporation

25 Examples 1. To deploy a workload one may need to: Create two CICS regions (Transaction servers) A back end data base (DB2 for z/os) Connected with two MQ queues 2. Need to add a new WAS server to an existing infrastructure because: New workload coming online (after an acquisition of a company) Or because of new requirements for isolation of workloads IBM Corporation

26 Cloud Provisioning on z/os Delivery* POC now through end of 2016 Hosted Beta Early July through 2016 GA of V1 Planned for 12/ and 2.2 GA of V2 Planned for 12/ and 2.3 Sysplex (datasharing DB2) Metering/Capping CPU, Real Storage, DASD space By Tenant Other Resource Managers (such as WLM) You can request participation here: 01.ibm.com/marketing/iwm/dre/signup?source=stgweb&S_PKG=ov44345 *Statements regarding IBM future direction and intent are subject to change or withdrawal, and represent goals and objectives only IBM Corporation

27 Architectural Overview z/osmf z/os Management Facility Browser based user interface in z/os providing administrator and end-user tasks. Based on WebSphere Liberty. Cloud Services / Applications Business services (SaaS) built using the subsystems and infrastructure. Cloud Services / Applications - business services Workflows Each subsystem provides Workflow a set of guided Users jobs, commands, etc that configure their subsystem CICS/IMS/MQ/DB2/WAS subsystems, Cloud Service Providers UI / REST API Workflow Engine z/osmf Workflow Engine Heart of the Cloud for z/os Processes manual and automated actions (steps) with dependency tracking to accomplish a configuration activity System Definitions, Registry Resource Mapping Services Workflows may require resources from the operating system, like a user ID, a port/vipa, a file system, an SMF record (for auditing), or an entry in the workload management policy to set dispatching priority, etc System Instance Registry Provide a view in z/osmf of the registry and definitions used for a given system. Tenant Management To allow scoping and isolation for multiple administrator-like capability Resource Mapping Services SMF data Self-service provisioning with Tenant Mgmt z/os Operating System WLM RACF SMF data Collect SMF data to enable for chargeback of services SMF Resource Mgmt TCP/IP DFSMS IBM Corporation

29 z/os and Cloud We want you, our customers to think of yourselves as a service provider (deliver) You might just deliver a new userid You might deliver a new LPAR or an entire sysplex You might deliver middleware as a service, such as a CICS region or a WAS server You might deliver a DB2 table, or an MQ Queue, as a service Or you might deliver an entire application IBM Corporation

30 Summary Cloud levels the playing field It s about API s the equalizer We want you, our customers, to think of yourselves as Service Providers We are providing new capability in z/os to improve Configuration Management Etc. Driving towards the functions of: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service We are delivering z/os into the Cloud IBM Corporation
