RED HAT CLOUDFORMS <£J redhat Signs you may have a cloud agility gap: • You can quickly provision new servers, but have trouble providing enough IP addresses for them. • You cannot quickly find unused virtual machines, much less automatically remove them to free up resources for other applications. • You can quickly provision (or deprovision) servers as demand changes, but you cannot easily or automatically do the same for the associated storage or networks. • You cannot automatically reallocate compute, storage, and network resources for the best combination of agility, performance, and price as needs change. • You are still using time-consuming, brittle configuration scripts that fail if one part of your infrastructure changes.

And you may have given them something that looks like that. However, delivering a portal with scripted provisioning in a first-generation "cloud" isn't going to deliver the agility, service levels, and satisfaction that users are really looking for. They may be initially requesting self-service provisioning, but what they really want are self-managed systems to increase their agility. This paper highlights the current agility gap that private clouds have and how to achieve true business agility. THE AGILITY GAP There is a very strong, implicit assumption by users that their self-provisioned systems will be highly available and reliable, and will perform as required within the underlying cloud infrastructure. Providing only initial self-service provisioning without continuous monitoring and management of those systems, as well as the supporting infrastructure, will significantly constrain the service levels that your cloud can achieve. Limited or "cloudwashed" implementations run a very real risk of user dissatisfaction and increased costs; and they foster perceptions that IT cannot really deliver the agility they need. The management of underlying clouds must also be agile in order to handle fluctuations in user demand, to meet variable workload needs, and to continuously optimize resource allocation and utilization. Without back-end capabilities (e.g., service visibility, monitoring, life cycle management, dynamic resource allocation, etc.), deploying a front-end portal or service catalog will result in the rapid proliferation of unmanaged systems, and increase resource and management costs. To determine if your private cloud is truly agile, ask yourself if it can: ^ Provide visibility into the active configuration, processing, and performance of your cloud's infrastructure and the applications that run on it. i^Offer your cloud users maximum autonomy in selecting and ordering systems and applications for their business needs. ^Automate the orchestration required to provision servers, and the storage and network resources they require, while complying with security and regulatory policies. ^ Prevent a cloud-based application from hitting a threshold, indicating that it is running out of a resource (e.g., storage) and applying an automated, policy-based fix. RED HAT' CLOUDFORMS <£J redhat ^Automatically manage cloud workloads and performance to meet customer SLAs, while giving users and their managers real-time visibility into the resources they're consuming. ^Accurately meter your cloud's systems utilization, and reflect the corresponding cloud service for chargeback and showback. If you can't check each box, then your private cloud is not helping your users meet their business challenges as quickly and efficiently as they need to. The time to fix this is now, while you have enough time to plan the correct control and governance to deliver these agile services in a reliable and predictable manner. ARE YOU TRULY AGILE? Agility is what organizations want when they create private clouds,and IT decision makers are coming to terms with the limitations of their first-generation private cloud management strategies. Most are not getting the full benefits of their private clouds, the market researcher says, because they've created on-demand infrastructure provisioning, but not "the more sophisticated application- aware automation, workload balancing and performance optimization tools" needed to optimize the cloud over time as business needs change. This change may come from within the business. It might involve: • Adding or dropping production applications from the environment • The need for test environments for new applications • Access to corporate systems from mobile devices Change might come in the form of hardware or software failures, seasonal or business-related spikes in demand, the opportunity to enter new markets, or the opportunity to deliver new, transforma- tional products or services. Such changes may also come from outside the business. They could include dramatic and sudden shifts in demand for applications. Regulatory or legal action may force new safeguards on servers and data, and the auditing and tracking of those safeguards. Customer adoption of mobile devices may drive new volumes of traffic to the infrastructure, or demand a specialized presentation of data. Technology and market changes, including increased mobile demands, create new services and corresponding infrastructure demands. As organizations manage the introduction of these new services, the need to ensure them against potential infrastructure outages that affect the business becomes critical. In looking for agility to cope with such changes, users often cite Amazon Web Services when discuss- ing examples of public clouds. This common example implies, though it is not always articulated, the simplicity, self-service capabilities (and the accompanying independence from IT-imposed delays) elasticity, low cost, scalability, reliability, security, and regulatory controls of a traditional, in-house IT infrastructure. It ignores, however, the fact that such providers achieve extraordinary levels of staff productivity because they manage highly homogenous, standardized, and automated environments with tightly defined service menus and clearly articulated cost, usage metering, and SLA models. In order to deliver the same level of agility, private clouds must match at least some of these capabilities. redhat.com WHITEPAPER The Agility Gap in Today's Private Clouds 2 CLOUDFORMS RED HAT' <£J redhat PRIVATE CLOUD DEPLOYMENT MODELS Customers typically choose one of three private cloud deployment approaches: 1. Standalone project-The most common approach is a standalone project meant to support a limited number of applications. This involves a lower level of risk than an attempt to dramatically change the entire infrastructure, and is often aimed at newer, web-facing applications. However, it still requires the ability to scale over time, especially if these new applications succeed in driving business growth. 2. Cloud-in-a-box purchase-Another common approach is to purchase a "cloud-in-a-box" solution that combines pre-configured and pre-tested combinations of hardware and basic management software. While this proven architecture significantly reduces the delay and cost of testing and configuration, it involves higher up-front costs and integration into a federated management infrastructure. 3. IT infrastructure transformation-The most aggressive approach attempts to transform parts or all of the enterprise IT infrastructure to a self-service, dynamic environment in search of quantum leaps in cost savings and agility. The downside of this approach is its high cost and risk, as it requires significant process and corporate change, as well as a high level of ongoing professional services from a vendor. In some cases, the organization has successfully virtualized parts of its infrastructure, and is being pushed by the business to provide self-service capabilities for that infrastructure. Technologies that enable you to manage all three of these approaches, or any combination of them, will be extremely valuable, especially in cases where current virtualization consolidation efforts need to evolve to provide the full benefits of a private cloud. While the scope of deployment and the underlying technology may differ, each approach requires a true cloud infrastructure management solution to deliver true agility. However, most organizations have not invested significantly in products to support consumption-based capacity planning and change, nor in policy-based performance monitoring and management tools to drive real-time resource optimization and application performance improvements. They are instead attempting to reuse siloed, legacy tools for IT provisioning, monitoring, planning, analysis, and reporting that are unable to discover and optimize the new cloud environment. Such splintered efforts, may speed up resource provisioning but do nothing to streamline and automate the full life cycle of service management. Achieving true agility requires adding IT-enabled Infrastructure-as-a-Service (laaS) management capabilities to an organization's existing legacy management tools. redhat.com WHITEPAPER The Agility Gap in Today's Private Clouds 3 RED HAT' CLOUDFORMS <£J redhat AN EFFECTIVE CLOUD MANAGEMENT SOLUTION PROVIDES: • Highly scalable, detailed, real-time visibility across configuration, monitoring, provisioning, patching, policy, compliance, and problem management systems. • An analytics engine that can quickly factor current policy, performance, and resource availability information into decision making. • Role-based, model-driven automation for Day 1 provisioning and Day 2 workload optimization, workload shutdown, resource reclamation, and redeployment. • Integration with a wide range of existing management systems, CMDBs, service catalogs, and APIs. • High availability and failover. Source: IDC Beyond Self Service: Getting the Most Out of Your Investments in Cloud and Virtualization Management Mary Johnston Turner Research Vice President, IDC June 2012 IT TRANSFORMATION INFRASTRUCTURE-AS-A-SERVICE (IAAS) IT organizations should incorporate laaS capabilities that require automatic, policy-based management for the entire life cycle of all cloud components (e.g., compute, storage, and network). This management must continuously adapt to meet enterprise requirements for security, efficiency, and agility. To meet these requirements, cloud management platforms must provide the following capabilities: • A self-service portal or service catalog supported by features such as automated, policy-based provisioning and life cycle management. • A continuous, unified, holistic view of all cloud resources that proactively assures efficiency, performance, security, and compliance, and troubleshoots problems. This view includes the operational environmental state, configuration and performance data, contextual awareness of all cloud elements, services, workloads, resources, and users, as well as the automated, real-time classification (or tagging) of cloud elements based on policies that eliminate manual classification effort, latency, and error. • Automated policy enforcement and control for managed systems. This assures security and compliance while reducing the delays, costs, and errors associated with manually enforcing policies, changing system configurations, and changing the allocation of resources. • Intelligent workload management to ensure resources are automatically and optimally utilized to ensure service availability and performance. This includes policy-based orchestration of workloads and resources, the ability to simulate allocation of resources for "what/if" planning, and continuous insights into granular workload and consumption levels to allow chargeback, showback, proactive planning, and policy creation. • Capacity planning to anticipate and plan for future resource needs based on capacity, trending, data, and analytics. This includes the abilities to classify resources based on configuration, performance, capacity, cost, acceptable use, and locations. • Capacity management to dynamically and automatically assure the most efficient use of resources. This includes the ability to discover and track resource changes, provision and de-provision resources based on policies and demand, and identify the current condition of resources and the best fit for new workloads across compute, storage, and network resources. • Highly available and scalable service management to enable the publication and consumption of IT cloud services with provisioning, ongoing tracking, life cycle management, auto-scaling, and retirement. This includes a service catalog with role-based control over what various users and groups can request, automated service provisioning, reconfiguration and de-provisioning, and performance and utilization monitoring. An effective cloud management solution provides the intelligent orchestration of all IT resources. This orchestration enables resource allocations and configurations to be adjusted in real time, maximizing performance, security, and efficiency as business needs change. By providing intelligent and automated responses to unpredictable events, an enterprise takes advantage of the agility and cost savings that cannot be achieved by merely automating linear, pre-determined, and siloed processes. redhat.com WHITEPAPER The Agility Gap in Today's Private Clouds 4 RED HAT CLOUDFORMS <£J redhat WHITEPAPER The Agility Gap in Today's Private Clouds WANTED: TRUE AGILITY Enterprise IT organizations have made impressive strides in reducing initial provisioning costs by virtualizing servers, networks, and storage. However, they are finding that these first-generation private clouds cannot deliver true agility and cost savings over time, because they lack enterprise levels of adaptability, visibility, security, and management throughout the cloud life cycle. EFFECTIVE CLOUD MANAGEMENT IS MORE THAN SELF-SERVICE PROVISIONING IT IS ALSO LIFE CYCLE MANAGEMENT SELF MANAGEMENT WORKLOAD AUTOMATION OPERATIONAL VISIBILITY I OPTIMIZATION AUTOMATION INTEGRATION COMPLIANCE True agility from a private cloud requires intelligent, automated, policy-based management of the entire cloud infrastructure. Even those organizations that have not yet faced the limits of their private clouds will do so soon, as customers respond to new business initiatives, users develop new applications, enterprises enter new markets, and governments and corporations impose new security rules. The sooner an organization understands that today's private clouds represent only the tip of the management iceberg, the sooner they can deliver the true agility benefits of the private cloud.
