5 CIO Long Term Vision for SAP Virtualization & Cloud v v v v v v v v v

6 Business Drivers 5% reduc=on in expenses can result in up to 45% increase in net income (SAPInsider/ASUG/SAP) IT Budgets = 66% for running the business, 19% for growing the business and 15% for transforming the business (Gartner) Overall IT mission to do more with less. CIO Headache I am supposed to do the same job, but with less budget and headcount?

7 Cloud Computing Statistics 44% of enterprises considering private clouds (IDC) Cloud compu=ng services will reach that $225.5 billion market by 2015 (Global Industry Analysts) 82% of solu=on providers expect revenue increase with cloud/saas offerings (CRN State of the Market) 20% of all businesses will own absolutely no IT assets come 2012 (Gartner)

8 How Do You Define the Cloud? The Internet is the Cloud

9 How Do You Define the Cloud? Cloud compu=ng is internet- based compu=ng, whereby shared resources, soiware and informa=on are provided to computers and other devices on- demand, like electricity. h"p://en.wikipedia.org/wiki/cloud_compu7ng On- demand self- service internet infrastructure where you pay- as- you- go and use only what you need, all managed by a browser, applica=on or API. Cloud compu=ng is broken up into mul=ple segments including: Cloud Infrastructure, Cloud Plakorms and Cloud Applica=ons. h"p://

10 SAP Virtualization or Cloud Decision Is SAP Virtualization or Cloud Real? What is the criteria for making the right decision? What is the appropriate technology? What is the right level of virtualization or cloud? What challenges exist and how do we overcome them?

11 Is SAP Virtualization / Cloud Realistic? SAP Virtualization or Cloud Decision Traditional capacity planning requires significant Architectural planning Hardware provisioning Administrative logistics Application migration Operational procedures Virtualization/Cloud changes everything Compute, storage, and networking resources can be provisioned ondemand A layer of abstraction insulates technical professionals from SAP & underlying complexity Capacity is dynamic, atomic, and limitless Resources are free to innovate, create, and automate SAP application performance can be optimized Capital assets can be minimized Human capital can be deployed for higher-value work Business Impact 15%-25% reduction in SAP HW Server infrastructure across all landscapes: sandbox, test, development and production 20%-25% reduction in IT SAP Basis Technical Center of Excellence (TCOE) personnel and tasks 10%-15% reduction in IT Functional Center of Excellence (FCOE) personnel and application development activities

12 What is the criteria for making the right decision? SAP Life Cycle Time Software Selection Initial Implementation Benefits Realization Procure Deploy Exploit Retire 20% 80% End of Life 80 to 120 k$ per user over 15 years Activities: Support On going Improve Project Upgrade Project Lifecycle Cost: 40% 30% 12% 23% Infrastructure: Hardware Software Depreciate Depreciate Replace Replace 5% Year

13 Balanced Architecture Definition for SAP Balanced Architecture Definition for SAP An architecture where the right resources are allocated for the right workload[*] at the right 7me. - Ganesh [*] One size does not fit all

14 What is the right level of virtualization? SAP Customers as of today Customers desiring SAP Virtualiza=on or Cloud v Where do I begin? Customers who have par=al SAP Virtualiza=on to Cloud v Virtualized Applica=on Servers v HA configura=ons v Domains & Par==ons v Where do I go next? Customers who have completed SAP Virtualiza=on - Next Step as Cloud v Virtualized Databases v Virtualized Compute Resources v What can I do be[er?

15 Service Phases SAP Roadmap to Virtualization or Cloud Plan Design Build Manage Discovery Analysis Detailed design Pilot and test Implement Transition Continuous Improvement Create business case: Determine requirements Create processes and operational best practices for cloud environment Transition operations to new cloud model Continuous Metric Reporting Develop end state architecture and roadmap Develop detailed design Deploy cloud Infrastructure Compliance Determine platform strategy Profile Application characteristics Migrate Applications to cloud environment Governance

16 What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Perform a SAP CapEx & OpEx reduc=on assessment v Perform a SAP Virtualiza=on or Cloud Assessment v Is VIRTUALIZATION or Cloud Realis=c for your SAP Landscape??? v Complete vs. Par=al v Private vs Public vs Hybrid v Opera=ng System Choice: Windows or Linux (if Cloud) v Database Choice: Oracle, MS SQL Server, DB2, MaxDB v Landscape Inventory: Servers, OS, DB, Storage, Network & Applica=ons (includes Bolt- On & External applica=ons) v U=lize assessments (and SAPS requirement) to create a Bill of Materials for Infrastructure changes v Consider factors of addi=onal load: new SAP component, Upgrade or UNICODE conversion

17 What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Common Mistakes v 1 to 1 conversion sizing v Excessive or inadequate storage space alloca=on v Supportability of the SAP Landscape in the proposed environment v Non- Produc=on requirements v Hardware compa=bility requirements v Management Tools v Down=me Calcula=ons during Transi=on (if different Datacenter) Small Medium Large Sizing Calculations 200 Concurrent Users 2,000 SAPS 1,000 Concurrent Users 10,000 SAPS 5,000 Concurrent Users 45,000 SAPS Very Large 10,000 Concurrent Users 90,000 SAPS

18 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Design Considera=ons v Server Consolida=on v Sizing of Virtual or Cloud Environment (vcpu, Memory, Network ) v Business Con=nuance v Single Points of Failure v High Availability for SAP v Dynamic Resources Scheduling v Datacenter Failure (Facili=es) v Boo=ng OS from SAN/NAS Storage v Storage Failure v SAP Adap=ve Compu=ng v Backup & Local Recovery in a Virtual Environment v SAP System Refresh v Disaster Recovery

19 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Server Consolida=on v Few enterprise servers vs. Many commodity servers v Scalability: Enterprise vs. Commodity v Physical consolida=on v Logical consolida=on v Re- Hos=ng (Changing Plakorm) or Cloud Provider v Work- load consolida=on v Sizing considera=on for a Virtual or Cloud Environment v Alloca=on of vcpu s based on workload v Decision related to Memory commitment for SAP Systems v Deploying Virtual machine files on Shared Storage (Very Important) v Path redundancy and SAN Fail- Over capability v Recommended to have 2 Separate Network at the least (Private / Public) v Private (SAP Traffic between VM s) v Public (VM s and End- Users)

20 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Storage considera=ons (Big Challenge with Cloud) v Combina=on of VMFS & RDM is recommended for SAP Landscape. v VMFS is primarily used for Guest OS and v NON- Produc=on SAP Systems normally resides on VMFS for easier administra=on and management. v RDM (Raw Device Mapping) is used for Produc=on SAP Database files. v Cluster Data & Quorum disks need to be configured with RDM. v RDM can be used in environment where disk based backup cloning solu=on are required. v RDM is required when migra=ng from Physical Servers to Virtual. v Recommend spreading Database Files into mul=ple Luns or Volumes for be[er I/O Performance. v SAN Design plays a vital role to ensure seamless Failover. v Boo=ng OS from SAN Storage simplify Disaster Recovery.

21 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v High Availability considera=ons v Ability to recover from Hardware Failure. v Ability to recover from Applica=on level Failure. v Network redundancy in Server Service Control is recommended. v Third Party Cluster is required to handle SAP Applica=on Monitoring and Failover. v Load Balanced Cluster design for Failover. v SAP Adap=ve Compu=ng considera=on v SAP Adap=ve install is recommended for Virtualiza=on. v SAP ACC agent need to be installed for V2P requirement (Virtual to Physical)

22 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Backup & Recovery v Guest OS based Backup v Storage Based Mirroring or Snap- shot based v Local Service Level Agreement (SLA) to meet. v Consolidated Backup on Proxy Server v Applica=on Integrated Backup & Restore capability v Backup to disk with De- duplica=on v Disaster Recovery v Repurposable SAP Data Centers are highly recommended v PROD, TRN & SBX on Primary / QA & DEV on Secondary Site v Tes=ng without effec=ng Produc=on v RTO can be minimized using automated recovery tools (SRM) v Designing Restartable or Recoverable copies. v Federated Point in Time Consistency required for SAP DR. v Most importantly not only to Fail- Over but need to Fail- Back.

23 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Private, Public or Hybrid cloud architecture v Customers with completely virtualized SAP landscapes should include a cloud service model in their roadmap for the ability to seamlessly scale their services in response to increasing demands. v Move your NON- Produc=on to Public Cloud (Virtual Private Cloud) by extending your network to bring cost down dras=cally. v Alloca=ng resources for on- demand System Copies, separate debug environments, and individual QA systems for separate projects with minimal opera=onal increase enables lowering IT barriers to innova=on. v Chargeback or Report Back v Once end- users are enabled (Private cloud), they need to be policed or resources will be over- allocated, under- u=lized and the tragedy of the commons occurs, thereby nega=ng the advantage of the infrastructure elas=city feature of the cloud.

24 What challenges exist and how do we overcome them? What challenges exist and how do we overcome them? Customers desiring SAP Virtualiza5on or Cloud v Address Disaster Recovery Plans v Disaster Recovery Plans for a completely virtualized landscape can be augmented by automa=ng applica=on recovery steps and developing processes and procedures for a successful failback to primary site. v Disaster Recovery Fail- Over to Public (VPC Providers) reducing cost of maintaining DR facility. v Complete landscape virtualiza=on v SAP applica=ons that are not based on SAP NetWeaver Applica=on Server ABAP or Java are not currently supported for virtualiza=on. The landscape can be considered completely virtualized only when all these components are supported for virtualiza=on by SAP.

25 Cloud Model Benefits and Risks Benefits Speedy deployment (the app, hardware, network should already exist) Vendor maintained exper=se Leveraging the latest in technology Lower overall Total Cost of Ownership (or just Total Cost) On- Demand resources and licensing Risks Mul=- tenancy concerns performance, availability Security access, compliance, data Most apps today allow for limited customiza=on Interfaces and/or interface development may be limited Less control over environment Time to enhancement modifica=ons and patches

26 What Does the Cloud Mean to SAP Customers? What it is Opportunity to leverage best TCO solu=ons for your organiza=on Business Opportuni=es: Prototype new applica=on with li[le or no up front investment Dynamically grow resources as needed On- Demand Licensing as you need The cloud has bridged the gap to allow access to applica=ons anywhere Another tool in the IT belt to be used where appropriate What it is not An end to current mainstream SAP architecture Complete replacement of your current landscape It is not a perfect fit for all situa=ons or all customers A compu=ng environment without issues

27 Questions to Ask Before Leveraging a Cloud Solution 1. What is your defini5on of Cloud compu5ng? Make sure you and your team are speaking the same language first Be very clear with vendors on your defini=on

28 Questions to Ask Before Leveraging a Cloud Solution 2. What are your business objec5ves? Determine your business objec=ves, then the goals and strategy that fit them Core applica=ons Infrastructure 3 rd party applica=ons Business drivers Costs Exper=se Loca=on 3. What are your business objec5ves? Security GRC Concerns (ITAR, PCI) Mul=- tenancy concerns Data security SLA s

29 Questions to Ask Before Leveraging a Cloud Solution 4. How important is custom development/customiza5on to your organiza5on Does a cloud solu=on provide the required flexibility? 5. What interfaces must be accounted for? What requirements do you have? How oien do they change? 6. How do you calculate ROI? Infrastructure License fees Support/Maintenance fees Training Labor costs Upgrades costs Capital expense vs Lease or rent Over how many years?

30 Wrap-Up Wrap Up An architecture where the right resources are allocated for the right workload[*] at the right 7me. - Ganesh v The Balanced Approach v One size should not fit all. v Use resources effec=vely and appropriately. v If all resources are virtualized or on cloud, flexibility is guaranteed. v Efficiency and Effec=veness are our goal. v Holis=c approach to Virtualiza=on or Cloud design. v Challenge Everything v Ask Why are we doing it this way? v Ask Can we leverage this for tomorrow? v Ask Are we op=mally u=lizing all resources? v Ask Does this address business requirements?

31 Definitions Mul=- tenancy Mul=ple customers sharing the resources, database and applica=on (like tenants in an apartment) Lock- in Refers to being locked- in to a cloud vendor s architecture, configura=on and requirements. Could lead towards monopolies by certain key vendors. Private Cloud An environment using the technologies of cloud compu=ng, but managed internally On- Premise Being physically located at the customer site

32 Definitions SaaS* SoWware as a Service Applica=ons on the Net that are generally sold per user by month IaaS* Infrastructure as a Service Outsourced infrastructure in terms of servers, storage and networking. LaaS Landscape as a Service Generic SAP specific landscapes that are hosted on a project or full =me basis PaaS PlaYorm as a Service An IaaS configured for a specific purpose or development plakorm
