2 1. Introduction 2. Hardware Consolidation 3. Legacy Migration 4. Mobile Enterprises 5. Conclusion & Status Quo 6. Questions & Discussion

3 Hardware and platform virtualization in desktop and data center environments is well-established The topic of Mobile Virtualization appeared around spring 2008 in mainstream media Hastily response to the iphone introduction?

4 Motorola Evoke QA4 First mobile handset that employed virtualization to support two concurrent operating systems on a single-core processor.

5 Why mobile virtualization? Hardware consolidation Legacy migration Application and services security Mobile-to-Enterprise connectivity

6 Design and deployment investments in smartphones vs. market expectations Insufficient battery life Limited performance Not enough DRAM and flash storage Bottlenecks in inter-chip connectivity Optimization approaches Standard approach: Optimization of the components Alternative approach: hardware consolidation trough mobile virtualization

7 Revised smartphone architecture Consolidate multiple chipsets into a unified CPU Migrating applications, baseband, multimedia and other dedicated chipsets into a single virtualized CPU Exchanging dedicated interconnects for shared memory interfaces Introducing a hypervisor

8 Optimized smartphone architecture

9 Benefit: reduced Bill of Materials (BOM) CPU consolidation DRAM consolidation Smaller battery Possible savings on BOM Migrate to Application Processing Unit (APU) 12 % reduction Migrate to Baseband Processing Unit (BPU) or equivalent 28% reduction Approach used for Motorola Evoke QA4

11 Legacy Code Leveraging the investments in baseband stacks and legacy Real Time Operating Systems Can be adapted and enhanced to run it on the new device without altering or changing new application stacks Reuse existing key features of already developed devices

12 Hardware and Operating System migration Once a design is virtualized, any future port to a different hardware architecture is greatly simplified Assumption 1: Hypervisor is available for the new hardware architecture Assumption 2: The operating system is adapted and deployable in a virtualized environment Benefits Faster Time-to-Market Reduced development expenses

13 Mobile workforce More than one billion mobile workers find themselves outside the corporate headquarters This is a third of the global workforce Observations Am employee often carries two cell phones, one for private purposes and one for business purposes Enterprises (should) maintain strict security policies which also apply to mobile devices Bring Your Own Device (BYOD)

14 Pillars of enterprise mobility Secure deployment of enterprise apps and access to corporate data and services Protection of user privacy and separation of worker and employer assets Freedom to use all available device functionality, including the ability to install applications and freely surf the web

15 Challenges for mobile enterprises Security: Malware, direct attacks, data-communication interception, physical compromise Privacy and functionality: BYOD and security policies Mobile device provisioning and management: Deployment paths and mechanisms Device management

16 Mobile virtualization as solution Security: Componentization and virtualization Secure execution environments Privacy and functionality: Strict partitioning of private and business data Enforcing rigid security policies Mobile device provisioning and management: Corporate IT does not rely on operators/carriers Fine-grained control mechanisms for mobile device management

17 Secure mobile communications architecture

18 Secure SMS Proof of Concept on Nokia N900 ARM Cortex A8 single-core 600 MHz 256 MB DRAM, 32 GB NAND Flash

19 Mobile virtualization provides valuable benefits for manufacturers and consumers Handset manufacturers can diminish production costs (software) and improve Time-to-Market Mobile enterprises are able to enforce the required security policies to protect their business assets Mobile workers only need one device for work and private purposes

20 At the moment, there are three major companies for mobile virtualization Mobile virtualization is already in use OK-Labs deployed already over 1.1 billion mobile phones with their hypervisor

21 VMware has also a fully functional prototype

23 Question 1 Value of Mobile Virtualization Is Mobile Virtualization just another hyped IT trend, or does it provide real benefits?

24 Question 2 Mobile Virtualization and market penetration What could be possible reasons for not already using mobile virtualization widely on mobile devices?

25 Question 3 Mobile Virtualization vs. Cloud Computing vs. Virtual Desktop Infrastructures Is there a technology to favor or does a mix of those technology provide the most value for enterprises?

26 Question 4 Standardization for mobile device management Is an open standard for mobile device management desirable (e.g. thinking of Web Based Enterprise Management integration or a solution similar to Blackberry Enterprise Server)?

27 Question 5 BYOD The acclaimed benefit of the Bring Your Own Device strategy is the cost reduction for enterprises. Does this cost cutting strategy really make sense?
