3 accelerate your ambition 3 Copyright © 2014 Dimension Data Topics covered – high level business and technical Our Engineered Systems Story Who is Dimension Data, the market drivers and why this is Strategic? The Market Opportunity Technical architecture and implementation challenges The Future

4 accelerate your ambition 4 Copyright © 2014 Dimension Data Shrink your service delivery costs by Oracle’s Strategy for Dimension Data Reducing the number of managed objects Simplifying management Reducing maintenance Standardising the stack for consistency Single stack support

5 accelerate your ambition 5 Copyright © 2014 Dimension Data Oracle’s Most Advanced Technology Exadata Storage Servers Oracle M-6 and T-5 Microprocessors 24-Terabit Silicon Network Oracle VM and Solaris Virtualisation Oracle SuperCluster Oracle's Most Powerful Engineered Systems World Record Oracle Database and Application Performance & Scalability Software Defined Secure Multi-tenancy Outstanding Affordability and ROI

6 accelerate your ambition 6 Copyright © 2014 Dimension Data Low cost Optimised OS & server Exadata Storage Zero-overhead virtualisation Dynamic resource allocation Single stack support Performance Exadata Storage Fastest microprocessors Software-defined everything Silicon network InfiniBand Reliability Factory tested & Integrated No SPF architecture Platinum support End-to-end automation Simplicity Designed for ease of use System-wide management Self tuning Oracle SuperCluster – Enabling Multi-Tenant Enterprise Cloud

7 accelerate your ambition 7 Copyright © 2014 Dimension Data Virtualisation Multi-layer secure and highly efficient virtualisation to maximise workload efficiency and increase the workload to payload ratio Key “Cloud” Decision Characteristics Resource Isolation Shared environments allow better use of spare capacity and much greater efficiency Workloads should still be guaranteed minimum resource levels Metering and Chargeback Ability to measure and charge based on specific consumption of resources (CPU, Storage, Network…) Management Maximise operational efficiency by reducing the number of objects to be managed and standardising the infrastructure stack

8 accelerate your ambition 8 Copyright © 2014 Dimension Data Topics covered – high level business and technical Our Engineered Systems Story Who is Dimension Data, the market drivers and why this is Strategic? The Market Opportunity Technical architecture and implementation challenges The Future

9 Dimension Data today 2013 global revenues of USD 5.8 billion 73% of Global Fortune 100 and 59% of Global Fortune 500 are Dimension Data clients Client-centric, services-focused business Extensive experience in emerging markets Over 25,000 employees with operations in 58 countries across 5 regions Over 6,000 clients across all industry sectors

10 Copyright © 2014 Dimension Data Our corporate footprint Preferred Partners Dimension Data Direct in 58 countries with preferred partners across an additional 114 countries

11 Copyright © 2014 Dimension Data High level architecture Private Cloud Public Cloud Client Zones Client Zones Production Pre-production Test Redundancy over separate datacenters IaaS ApaaS DbaaS PaaS

12 accelerate your ambition 12 Copyright © 2014 Dimension Data The challenge – build or buy? Increasingly complex environments and multiple vendors Long lead times to deploy applications Huge capital outlay for high-performing environment Licencing and maintenance of testing, pre-production and production environments Business disruptions due to downtime Compliance and risk exposure

13 accelerate your ambition 13 Copyright © 2014 Dimension Data What is Engineered Services for Oracle Leverage License savings and extreme performance Scale compute and storage up or down as you need it Fastest, most scalable engineered system for Oracle solutions Test and Development as a Service True Platform as a Service

14 Copyright © 2014 Dimension Data *Source: IDC, Software Vertical Spend | CAGR Compound annual growth rate Why we did this? The South African and African market Oracle stated intent – not to focus on Africa The network, hosting facilities, client relationships and the skills First to market Value proposition - sticky Build a second tier market – of those who cant afford engineered systems

15 accelerate your ambition 15 Copyright © 2014 Dimension Data Why Dimension Data was well positioned to do this Client Skills Oracle Applications Database Backup and security Our network Hosting facilities Local and Africa

16 accelerate your ambition 16 Copyright © 2014 Dimension Data Topics covered – high level business and technical Our Engineered Systems Story Who is Dimension Data, the market drivers and why this is Strategic? The Market Opportunity Technical architecture and implementation challenges The Future

17 accelerate your ambition 17 Copyright © 2014 Dimension Data The South African and African market Potential

18 accelerate your ambition 18 Copyright © 2014 Dimension Data The market Algeria Angola Botswana Burundi Congo Democratic Republic Of Congo Gabon Ghana Accra (Internet Solutions Office) Kenya Nairobi (Head Office) Nairobi (Internet Solutions Office) Mombasa Nyeri Kisumu Eldoret Malawi Mauritius Morocco Casablanca Mozambique Namibia Windhoek (Head Office) Nigeria Oman Rwanda Saudi Arabia South Africa Tanzania Uganda Abu Dhabi Dubai Fastest internet speed averages 1.Ghana 2.Zimbabwe 3.Kenya 4.Libya 5.Madagascar 6.South Africa 7.Morocco 8.Nigeria 9.Rwanda 10.Mozambique

19 Copyright © 2014 Dimension Data The market The South African and African market Large second tier market At last we have the connectivity Fastest growing economy Capex vs Opex Local enterprise expansion into Africa

20 Copyright © 2014 Dimension Data Market challenges Ignorance and complacency Job protection Still want the data close to them Regulation – Data sovereignty Integration into dependant or legacy systems Clients don’t know enough about the product yet Perceived – lock in Perceived security issues Oracle’s Cloud Offerings Licencing pricing model

21 Copyright © 2014 Dimension Data Multi-tenancy on Oracle engineered solution IS WORKING Services include IaaS, PaaS, DBaaS, APaaS Storage, networking, compute backups and recovery part of the deal Security in the box and across the network is paramount Production always available with the agility to provide Test and Dev on demand Elasticity to grow and shrink on demand DR supplementary for production Essentially a utility provider Plug in and work Managed infrastructure

22 accelerate your ambition 22 Copyright © 2014 Dimension Data Topics covered – high level business and technical Our Engineered Systems Story Who is Dimension Data, the market drivers and why this is Strategic? The Market Opportunity Technical architecture and implementation challenges The Future

23 accelerate your ambition 23 Copyright © 2014 Dimension Data Engineered solutions means Client benefits Amortise costs across many organisations Opex vs.Capex Lower costs – Higher ROI PaaS - Focus on your business applications not the infrastructure environment Pay as you grow – resourcing when you need it Secure and isolated Fully redundant

24 Copyright © 2014 Dimension Data The experience – the good and the bad Licencing – No shared model licencing Multi-tenancy as a concept to Oracle Security Network isolation – complex firewall routing Provisioning – cumbersome Great team from oracle Underestimated 3rd party reliance on the data
