Our Hosted Private CaaS provides clients with a secure and segmented hosting environment that s unique to each client, and is isolated from the rest of the private hosted cloud. The Hosted Private CaaS is deployed in Dimension Data data centres and is available for a fixed monthly fee. It provides a variety of options and allows you to manage different customer accounts within the private cloud architecture, including the ability to provide monthly usage metrics of each internal customer to facilitate cost chargebacks. TOP 5 FACTS ABOUT DIMENSION DATA S PRIVATE HOSTED CaaS Dimension Data s Private hosted CaaS is: High quality and high performance cloud computing for government and large organisations Provided via the Internet or by clients dedicated MPLS private network in scalable, pay- per use model Build using industry leading hardware and software Fully automated and orchestrated via purpose- built software Comprises Servers, tiered storage and network elements coupled with WAN optimisation virtualisation technology and operating system software Deployed in one of our data centres (e.g. London) and available for a fixed monthly fee 3

This includes responsibility for maintaining the following: Physical infrastructure (servers, networking equipment, and tiered storage) Underlying operating systems VMware software Dimension Data CloudControl cloud management system 5

Dimension Data s management processes address the key elements of implementation, change control, monitoring, patching, and lifecycle management so that cloud availability and performance are maintained. Ongoing software lifecycle management is a key component of the Hosted Private CaaS. Dimension Data evaluates all major software releases from VMware, Cisco and the other components of the solution, and tests these releases within its lab environment to ensure they function as expected. Furthermore, Dimension Data will review new features and capabilities of any releases and will update its operating system, virtualisation and Dimension Data CloudControl software to allow you to take full advantage of new software. Dimension Data s multipoint monitoring systems scrutinise key system parameters, system availability, network and the overall user experience 24x7x365 to ensure the highest possible uptime and performance. GLOBAL SERVICE CENTRE Dimension Data s monitoring systems report to a central aggregation engine that drives Dimension Data s Private and Public CaaS client care and technical support for all emergency or after hours client- to- Dimension Data communications. The 24x7x365 Client Care Centre has the tools, technology, and administrative expertise to effectively support customer environments, including: 24x7x365 staffing with experienced technicians first- level support is via our Global Service Centre; Level 1 and Level 2 industry expertise to resolve Severity 1 and Severity 2 issues immediately; In- depth domain knowledge, escalation management expertise and a focus on client satisfaction. Hosted Private CaaS clients also have the choice of providing their end users with access to the Dimension Data s Cloud Community. The community provides users and developers with the support, education and knowledge base to use the service to build applications on the Dimension Data s Cloud. In the case of an Incident, a client will need to provide sufficient explanation of the circumstances under which the Incident occurred or is occurring. Dimension Data will reasonably classify each call as an Emergency Incident, Other Incident or Service Request. If a call is misclassified initially, Dimension Data may reclassify it and respond accordingly. On each call, the GSC representative will assign a unique ticket number to Client, which Client can use to track its request. Following receipt of a client s Incident report or Service Request, Dimension Data will contact the client via email or telephone to: provide them with information regarding the Incident or Service Request; and collect any additional information from them necessary or useful to facilitate Incident Correction or to respond to the Service Request. 6

In addition to its Compute- as- a- Service offerings, Dimension Data offers to clients who have ordered Dimension Data s Hosted Private CaaS certain additional services called Tech Ops Services. The Tech Ops Services are intended to provide basic system administration services such as operating system (OS) support, system monitoring and server backups for designated Cloud Servers. In order to enable Dimension Data to perform Tech Ops Services, a Client is required to make Dimension Data a full access Sub- Administrator for Client s CaaS account, so that Dimension Data can help manage the Client s CaaS environment and perform system administration tasks on Client s designated Cloud Servers. Tech Ops Services are billed based on a monthly per- Cloud Server fee and the pricing is covered in the pricing document. For more information on Technical Support Services please see: http://www.dimensiondata.com/global/services/cloud- services/pages/caas- tech- ops.aspx 2.2 Customer Responsibilities Here are some of the key responsibilities we wish to highlight, a full list is contained within the supplier Terms and Conditions that apply to this service. ACCESS AND AUTHORISATION The client will take commercially reasonable steps to prevent unauthorized access to or use of the service and that users authentication details are protected. Should any unauthorised access or use occur, the client must notify Dimension Data promptly. 2.3 Client- Side Technical Requirements CONNECTIVITY The client will be responsible for the control and management of access and responsibilities for end users including appropriate connectivity, security and accreditation if required. Where access to our services is via a dedicated network (PSN/GSi) the customer is responsible for maintaining and adhering to the code of connection and network policies that apply. You are also required to assign appropriate IP address from you own allocation to your hosting platform, which is constructed of services supplied by Dimension Data. 2.4 Service Constraints There aren t any constraints with this service. 2.5 Planned Maintenance Windows Dimension Data performs scheduled maintenance on the services (including maintenance related to the Software, MCP and other equipment and materials used for providing the Services) from time to time. In addition, Dimension Data may occasionally need to perform emergency or unscheduled maintenance; these maintenance activities may cause interruptions to the services. Dimension Data will use reasonable efforts to inform every client in advance of any such service interruptions and their anticipated duration. Additional information regarding 7

Dimension Data s maintenance policies and procedures is located at http://www.dimensiondata.com/services/cloudservices/caas/public/maintenance 2.6 Back Up / Restore and Disaster Recovery Unless backup services are included in the order as part of Tech Ops Services, Dimension Data will not be required to create, maintain or implement backups of any client content and that the client is solely responsible for such backup services. BACKUP OPTIONS If backup is requested, Dimension Data s Cloud Backup is available in three plans: Essentials files and folders backup and restore Advanced files and folders, as well as system state backup and restore Enterprise files and folders, system state as well as application backup and restore. These options are covered in the Pricing section of this document. 3 Training Dimension Data Professional Services can engage to provide training to administrators and users of the platform. This is a chargeable activity, but, due to the intuitive nature of the platform is rarely necessary 4 Information Security 4.1 Security level targeted We are targeting OFFICIAL - Assured Cloud and OFFICAL- SENSITIVE - Accredited Cloud. We are planning to embark on the process of Pan Government Accreditation following our G- Cloud 5 submission. Currently our service is classified as Unassured Cloud. 4.2 Current security standards and certifications Dimension Data is accredited to ISO27001, the international security management standard. We operate very robust processes for safeguarding data and for maintaining the confidentiality of information. We are currently undertaking a gap analysis of the scope of the ISO27001 accreditations for the company, the data centre and this service. The outcome of this process will be a suitably scoped ISO27001 certification that will cover this service, which we aspire to take forwards through PGA accreditation at OFFICIAL and OFFICIAL- SENSITIVE. Current Security Controls Network configuration Configurable Layer- 2 VLANs based on Cisco- based switching fabric; Customisable ACL- based firewall rules; NAT and VIP functions; Load- balancing and port translation; Multicast support for clustering implementations 8

Cloud files encryption Access Administrative control Server control Reporting Compliance Incident response API Data stored with 256- bit encryption at rest and 128- bit SSL encryption while in transit Public Internet and virtual private network (VPN) VPN administration of all servers; Unique username and password for multiple administrators; Role- based permissions allow administrator to limit sub- administrators to manage only certain resources, such as servers, tiered storage or networks. Take servers in and out of service manually, programmatically, or based on monitoring probes Audit logs of all environmental changes SSAE 16 (formerly SAS70 Type II) compliant; US- European Union Safe Harbor Certified 24x7 incident response REST- based API 4.3 Data Storage and Processing Locations Top- tier co- location facilities in San Jose, California and Ashburn, Virginia, USA; Amsterdam, the Netherlands; London, UK; Sydney, Melbourne, Australia; Johannesburg, South Africa; Tokyo, Japan and Hong Kong. All of our facilities have the following: o Meets Uptime Institute Tier III standards. o Monitored 24x7x365 by CCTV and onsite guards. o Access through biometric two- factor authentication. Clients are able to select which cloud locations they use, Dimension Data will not move their compute or storage away from the location specified (e.g. London); however, if clients want to use service in other geographies this is able to be achieved via the single management portal. A CLOUD MANAGEMENT PLATFORM ENABLING GLOBAL AVAILABILITY Dimension Data s CloudControl cloud management system enables federation between Public and Private Managed Cloud Platforms (MCPs). Our strategically- located Public MCPs have the ability to interconnect or peer with one another and other Private MCPs, as capacity requirements ebb and flow to create a Cloud Exchange. This means performance and latency may be optimised and time- to- service reduced. This model also ensures that any data sovereignty requirements on a client s part may be satisfied. 9

4.4 Data Extraction and Removal There are no extra charges for removing data from the service, the customer will only have to pay for the bandwidth used when transporting data away from their cloud services. 5 On- boarding 5.1 Deployment A client may request Services by submitting an Order to Dimension Data. This can be placed via the G- Cloud order form and contacting Andy.Lancaster@dimensiondata.com. Dimension Data will, on the completion of an order being placed issue a Welcome Pack. The Welcome Pack will include credentials to enable the designated administrator to access the services. A client will be deemed to have access to the Services on the date Dimension Data issues the Welcome Pack. Dimension Data will keep a record of the effective date for each order and each order will set forth the particular plan ordered and the applicable fees. 5.2 Configuration and Customisation CLOUD SERVERS Built on VMware s vsphere Hypervisor, Dimension Data cloud servers are highly configurable, secure, virtual machines that provide granular control and allow easy customisation. Each cloud server can be configured with anti- affinity and up to 16 CPUs, 128 GB of RAM and 10 TB of tiered storage. Dimension Data offers three levels of tiered storage, including: High Performance for mission critical online active files and database tables that require always- on availability Standard ideal for Cloud applications using VM/VDI files, archiving of videos and images Economy for offline master backup, disaster recovery and long- term retention To easily and seamlessly ensure business continuity and data protection while also offering choice; cloud backup is delivered through a self- service portal. These options are covered in the pricing section of this document. Our secure virtual machines are hosted on physical servers in the Dimension Data enterprise- class private hosted cloud and are built on the infrastructures from Cisco, EMC and Dell. Dimension Data cloud servers support Microsoft Windows, Red Hat Enterprise Linux, Ubuntu and CentOS operating systems and can be deployed and managed either through the administrative UI or through corresponding functions of the open API. CLOUD NETWORKS Cloud networks are VLANs built on Cisco hardware- based networking providing network isolation, security and performance for your environment. Cloud networks can be 10

customised with additional networking features such as firewalls, load balancing, multicast and network address translation (NAT). Additional features include the following: o Private IP addressing for all cloud servers, with the ability for cloud servers located on separate cloud networks to communicate across this private IP space o Client- to- site VPN access for administrators to securely manage servers on their cloud networks o Customisable ACL- based firewall rules to control access into each network VLAN o NAT and VIP functions to expose private IP addresses to the public Internet o VIP functions support load balancing and port translation across multiple virtual servers, with the ability to take servers in and out of service based on client- defined monitoring probes o Multicast support for clustering implementations 6 Off- boarding 6.1 Termination Policy Subject to any Minimum Commitment Term, either party may terminate the agreement or orders by notice to the other party, for any reason or no reason, with termination to be effective at the end of the last day of the calendar month immediately following such notice. Either party may terminate the agreement or any orders upon notice to the other party if the other party materially breaches any term or condition of this agreement or any order and fails to correct such breach within fifteen days following notice specifying such breach. Within our Private hosted Cloud service a client is able to do the following, which assist with on and off boarding: Cloning ability to duplicate virtual servers to create customer images which can be used to deploy copies of a server configuration Capability to import/export server images which can be used to transfer virtual machines to and from a client s own infrastructure There are no extra charges for moving away from the service, the customer will only have to pay for the bandwidth used when transporting data away from their cloud services. 7 Performance 7.1 Service levels The following Service Levels apply to Private Hosted CaaS (each Service Level and the terms and conditions that apply are described in more detail here: http://eucloud.dimensiondata.com/legal/service- Level- Agreement) 11
