zClouds - A better business Cloud

  1. 1. zClouds: A better Business Cloud© Satyam 2009 1
  2. 2. Mainframe - Practice Highlights Agenda Cloud Requirements System z Features Summary zCloud Use Cases Questions© Satyam 2009 2
  3. 3. Mainframe - Practice Highlights Cloud Requirements Cloud’s basic requirements boil down to four : Scalability involves the Resilience is the ability to keep ability to grow large while going when infrastructure functionality remains elements fail. undiminished. Finally, a cloud must Elasticity is the ability to support Security add resources to requirements for support a service applications without disruption of operations© Satyam 2009 3
  4. 4. Mainframe - Practice Highlights Scalability  System z Virtualization along with Parallel Sysplex enables near linear processor scalability  Supports various workload instances on a basic set of resources (eg: Java,Linux,DB2)  System capacity can be plugged into existing and running systems  Parallel Sysplex environment can scale near linearly from 2 to 32 system z machines “Unchallenged Virtualization enables System utilization rates +80% and ¼ of the network costs of distributed capacity”© Satyam 2009 4
  5. 5. Mainframe - Practice Highlights Virtualization Massive virtualization capability supporting thousands of virtual Linux guests on a single Logical Partition (LPAR).  System z provides logical (LPAR) and software (z/VM) partitioning  PR/SM enables highly scalable virtual server hosting for LPAR and z/VM  IRD coordinates allocation of CPU and I/O resources among LPARs “… z/VM 5.3 and above can host more then 1,000 virtual images on a single hypervisor - topping any virtualization solution in the industry." The value realized at the infrastructure level is then permeated into PaaS and SaaS© Satyam 2009 5
  6. 6. Mainframe - Practice Highlights The Power and Flexibility of System z Virtualization  Over 40 years of continuous innovation in virtualization technologies  Multiple images concurrently share all physical resources  Resources delivered as required, automatically, based on need  New OS images can be started without affecting on-going work  Hardware assists used to accelerate virtualization operations© Satyam 2009 6
  7. 7. Mainframe - Practice Highlights Parallel SYStems comPLEX With IBMs Parallel Sysplex technology, you can harness the power of up to 32 z systems.  Parallel Sysplex cluster contains multisystem data and resource sharing technology  The combination of Parallel Sysplex and Intelligent Resource Director enables your e-business application to take full utilization of servers’ resources  Work requests that are associated with a single workload can be dynamically distributed for parallel execution  Manage multiple systems as a single system from a single point of control “Every server in a Parallel Sysplex cluster has access to all data resources and every "cloned" application can run on every server “© Satyam 2009 7
  8. 8. Mainframe - Practice Highlights Resilience  The System z product line is designed to offer fault tolerance to reduce single point of failure(SPOF). Mean time between failure(MTBF) is measured in decades  Quick retargeting of spare instances of application elements, facilitated by virtualization  Parallel Sysplex and Globally Dispersed Parallel Sysplex(GDPS) ensures near continuous availability “System z provides fault tolerance for all of its key components. This includes not just the CPs, memory or I/O, but also the timing oscillator card, power supply, channel paths and others.”© Satyam 2009 8
  9. 9. Mainframe - Practice HighlightsHyper swap feature enhances the resilience of Parallel Sysplex by facilitating theimmediate switching of PPRC mirrored disk subsystems.  HyperSwap, a software technology that can seamlessly substitute Metro Mirror (peer-to-peer remote copy, or PPRC), secondary devices for PPRC primary devices  GDPS helps automate recovery procedures for planned and unplanned outages to provide near-continuous availability and disaster recovery capability.© Satyam 2009 9
  10. 10. Mainframe - Practice Highlights Elasticity  The virtualization, resource allocation and coordination are built into the platform  Shared everything enables less components and a more simplistic IT foundation  Supports capacity upgrade on demand (CUoD) and on/Off Capacity on demand(on/off CoD) that is transparent to end users  Cost Per Image for Linux workloads is lowest for a z/VM based private cloud by adding IFLs to existing System z infrastructure© Satyam 2009 10
  11. 11. Mainframe - Practice Highlights CUoD & On/Off CoD  Capacity Upgrade on Demand (CUoD) allows for the non disruptive addition of central processor capacity  CUoD can quickly add processor capacity up to the maximum number of available inactive engines.  On/Off CoD gives you the ability to rent hardware capacity by the day  You can turn on/off processing units or Integrated Facilities from your original configuration  You pay only for the days the processing units or Integrated Facilities are turned on. CIU (Customer Initiated Upgrade) is a Web-based solution for customers ordering and installing permanent upgrades by creating an order on IBM Resource Link and utilizing the System z Remote Service Facility (RSF) for downloading and activation.© Satyam 2009 11
  12. 12. Mainframe - Practice Highlights Cost Per Image for Linux workloads (5 Yr TCO) TCO over 5 years for running 100 Linux images using five different platforms:  Buy stand-alone x86 servers (running one image/workload on each)  Rent Amazon EC2 instances (running one image/workload on each)  Buy large x86 servers and provision virtual servers using an x86 hypervisor (private cloud)  Upgrade an existing z10 EC machine and provision virtual servers using z/VM (private cloud)  Buy a new z10BC machine and provision virtual servers using z/VM (private cloud) “Private cloud implementations built around larger virtualized System z servers can be up to 77% less expensive than public cloud options over a five year period and around 81% less than a distributed stand-alone server approach”© Satyam 2009 12

  14. 14. Mainframe - Practice Highlights Security  Extremely high levels of security for guest operating systems  Hardware Registry  Virtual Address Space  IOCDS Definitions  z/VM user definition and z/VM security is accomplished by the z/VM directory.  ESMs like Resource Access Control Facility (RACF) provide additional centralized security functions  The cryptographic co-processor  The z/OS IDS uses policy-based - rather does encryption in than signature-based - identification with hardware, reducing the capabilities for detecting and preventing not performance penalty only known attacks, but also new attacks  With z/VM you can setup the for which there are no developed attack TCP/IP connections to the z/VM signatures. guests to be protected by Secure  zSeries hardware partitioning was the first Socket Layer (SSL). product of its kind to be awarded EAL5  Uses the internal Hipersockets to (Evaluation Assurance Level) reduce the security risks that come international common criteria security with network externalization certification.© Satyam 2009 14
  15. 15. Mainframe - Practice Highlights  Every component in the box operate in full isolation for security and recoverability.  Components are integrated through memory-to-memory speed hipersockets (In-memory TCP/IP network) reducing intrusion points to minimum.© Satyam 2009 15
