Market Situation IaaS has 24% market share among U.S. enterprises 37% of U.S. enterprises expects to deploy IaaS in next two years 60% of above has plan to deploy IaaS in the coming year Source: Yankee Group 2010

Target Users Industry & Size Project Nature Non industry or company size specific Project Nature IP-based applications on x86 / x86-64 servers No specific hardware needed by application To offer public e-services To deal with dynamic needs (in terms of capacity and duration)

Target Users (cont.) Corporate IT Practice Typical Usage High comfortable level of using external IDC service (server rental or colocation) Want to reduce CAPEX and OPEX for maintaining servers in-premise Typical Usage Enterprise application, e.g., ERP, CRM, Email Intranet/Extranet application, e.g., Workflow/Logistics, eDM Public content, e.g., Web server, FTP server

Infrastructure-as-a-Service (IaaS) Including Software: Operating System and Application Cloud Computing: x86/x86-64 CPU + RAM Private LAN: customized vLAN design Storage Network: iSCSI SAN & Storage Capacity Optimization: Content Delivery Network, Server Load Balancing, vFirewall, WAN Opt. CDH Network & Bandwidth: Internet / Private WAN / Intranet Environment: Industry Standard IDC Management: Monitoring & Maintenance Monthly recurrent charge model Colocation

A Platform for IP Applications Provide root / console access for Linux OS and Microsoft software (SPLA) Ideal for running below applications Enterprise application, e.g., ERP, CRM, Email Intranet/Extranet application, e.g., Workflow/Logistics, eDM Public content, e.g., Web server, FTP server Note: Real-time applications (voice, video) are not suggested and applications which require special hardware are not supported to run on CDH platform.

Benefits of CDH Economical Benefits No Startup CAPEX Lower OPEX Computer room facilities (UPS, Air-con etc.) IT equipment (router, switches, server etc.) Lower OPEX No maintenance fee for computer room facilities No maintenance fee for hardware No travelling cost Simple management and much lower admin cost

Benefits of CDH (cont.) Productivity Benefits Short provisioning time Within three working days as opposed to 4-6 weeks (no hardware purchase and logistics administration) Minimized outage with uptime SLA Industry Standard IDC environment High Availability option (fast auto server restart) Fault Tolerant option (zero down time) Full redundancy for system, power supply and UPS-power Fast and Easy upgrade Dynamic resource allocation among ready-built larger resource pools (hardware and network) Minimum technology risk (investment protection)
