Instead, they’re being provisioned using multiple suppliers, each of which serves the business needs of a single part of the enterprise. The result is typically cloud sprawl. Delivering and managing an end-to-end integrated service from a multi-supplier ecosystem is more complex than traditional IT delivery. Join this session to learn how a converged infrastructure solution, using innovative approaches and technology from HP, can help manage cloud sprawl. We’ll help you better understand how to manage complex, diverse services ecosystems and how preconfigured integration of common cloud functions from HP and its partners can address common challenges. Learn about cloud brokering and integration with external cloud services to provide a reliable and measurable base for protecting enterprise data systems.

The information contained herein is subject to change without notice.4 Service broker Key concepts • A service broker is primarily a business value multiplier, not a technology • A broker can: − Add supplemental capability to existing services − Improve availability of services by managing redundancy, failover and bursting − Combine services to create new capability − Reduce cost though aggregation of demand − Enhance visibility of composite services delivery • Not all services can be brokered effectively Adding business value in the delivery of services Service intermediation A cloud broker enhances a given service by improving some specific capability and providing value-added services to cloud consumers. The improvement can be managing access to cloud services, identity management, performance reporting, enhanced security, etc. Service aggregation A cloud broker combines and integrates multiple services into one or more new services. The broker provides data integration and ensures the secure data movement between the cloud consumer and multiple cloud providers. Service arbitrage Service arbitrage is similar to service aggregation except that the services being aggregated are not fixed. Service arbitrage means a broker has the flexibility to choose services from multiple agencies. Definition: NIST SP 500-292, NIST Cloud Reference Architecture

The information contained herein is subject to change without notice.5 Platform Service Management Component measurement • Traditional Service Management looks for outages and incidents involving the configurable items (CI) in an IT platform • IT services are generally composed using multiple components which, working together, deliver a service • Operations staff work to detect and remediate component incidents to provide agreed service levels (SLA) • Management focus is on the components provided by a supplier and outages by external suppliers are treated as “carve-outs” Managing service components within a provider’s scope Platform Service Management Service components

The information contained herein is subject to change without notice.6 Hybrid Delivery Management Service measurement • Composite service management manages the impact to the business service, end-to-end • Platform service management is performed by each service provider • A hybrid delivery manager, or service broker, provides multi- supplier management and integration • Work may be moved between providers as needed to achieve optimal business value through service arbitrage Managing service providers as components of composite services Platform Service ManagementPlatform Service Management Hybrid Delivery Management Provider “B” service capability Provider “A” service capability

  • 11. © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.11 Expanded example: managing a composite mail service Service specific bridging and integration • Recognize that different providers of the same service work differently—users expect coherence • Identify where the gaps are in a particular service and add bridging technology to fill the gaps • In our mail example: – Meta directory to support GAL, keep track of who is getting service from where, mail routing to the right service for each user – Use gateways to support shared presence, protocol translation, shared calendaring, etc. – Keep a backup of critical mail stores, use file links for attachments to support rapid migration, recovery Be prepared to build a bridge: every service is different User Corporate LAN Enterprise DMZ Enterprise data center Directory Mail SAN Mobile network Internet Aggregation services

The information contained herein is subject to change without notice.12 Logical messaging and collaboration service Hybrid delivery management In an example use case: • A user selects a service from an online catalogue. • Based on organizational policies, the user is offered a range of service providers (qualified by price, performance, security and supplier, etc.). • User selects the service of choice: catalog determines if this is a new, changed, migrated or cancelled service order. • User selects configuration options and order is routed. • Service is provisioned: user can access status, training, etc. • Status, control panels, and alerts are provided for the user and enterprise administrator. • Once provisioning and data migration are complete, user has access to the new service, which is integrated with the services from other providers. • The instantiation of the service may vary for a user.

The information contained herein is subject to change without notice.13 Hybrid delivery management Considerations: • A hybrid delivery approach is best suited for systems where the data and its exchange and transport protocols are well defined • Stateless services are well suited to multi- provider hybrid delivery • Consider long term data storage vs. short term data processing needs • Mail, file storage, web services, collaboration, UCC and similar systems can be readily converted to hybrid delivery Cautions: • Combining systems with complex and proprietary data formats are less straightforward, as you have to move highly customized data formats and configurations around as well as the data. • Long running stateful lifecycle services are more difficult to broker to multiple service providers • For example, moving HR policies, general ledger charts of account and so forth. These systems are often not well suited to horizontal scale out in the cloud without an application re- design and so were beyond the scope of this discussion. Bridging and Multi-provider failover best practices
  • 14. © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.14 Start with a solid, measurable, integrated core Hybrid delivery best practices Enterprise data center core using converged infrastructure • A dynamic, virtualized server environment positions the enterprise to scale up, down or out into the cloud • A flexible storage environment can integrate information stored in the enterprise data center with cloud based storage • A flexible network fabric—moving towards software defined networking—provides the ability to safely extend the network to support mobile users, processes and data, safely Distribute and federate • Use the core data center as the authoritative source for protecting enterprise data • Distribute data for increased availability, flexibility and mobility • Move the processing to where the data is, you don’t always have to move the data to the process • Consider multiple suppliers for each service • It is possible to improve availability and security through distribution across providers or availability zones
  • 15. © Copyright 2013 Hewlett-Packard Development Company, L.P. The information contained herein is subject to change without notice.15 Manage platforms bottom-up and services top-down Hybrid delivery best practices Platform management • Understand the style of management an application demands – Some applications are designed to scale vertically, as the demand grows the platform must grow • Depends on hyper-reliable platforms: server outage = service outage – Look for applications designed for horizontal scalability, burst to new instances • Fault-tolerant and cloud-friendly: server outage = temporary performance degradation • Publish event and performance data to support service management Service management • Use platform published metrics and end to end probes to predict demand changes or impending faults • Understand how to scale each component of the end to end service and be prepared to shift workload • Always run active-active as unexpected failures constitute degradation, not outages • Understand the need for bridging technology to support hybrid/composite services
