If we’ve described the problem in the current economics of the data center, what does the future of IT look like? For many, it is best represented by the world of many clouds. This is what will allow IT to deliver services back to the business as opposed to being considered a cost center. If IT can make the shift towards more of these innovative projects, they stand a much better change of transitioning to IT as a Service and cloud. By harnessing the power of public, private, hybrid clouds or traditional data centers, they can more rapidly deliver value to the business. Although many customers will start with private clouds, which deliver pivotal functionality to they will also want to choose from offerings available to them via the public cloud. This has the benefit of eliminating the need for shadow IT that so many groups end up creating. It may not surprise you to realize that service providers around the world are launching their cloud services based on a Cisco Unified Data Center.
From the standpoint of internal IT, your business users demand and expect faster, better, more agile and dynamic IT services. But many legacy data centers are built on old technology that just wasn’t designed for the demands and pace of today’s business. The infrastructure is complex, it’s messy, and it’s ill-suited for the future of IT.And from a management perspective, most IT organizations have dozens of different systems that don’t necessarily work all that well together. If you’ve ever played Jenga, you know what happens when you try to remove the wrong block too quickly, it falls apart. That complexity and inherent fragility applies to most legacy existing IT systems – they are very expensive to manage and maintain, and many IT organizations are ill-equipped to meet the demands of the business for faster service delivery.For example, in most IT departments, the process for data center infrastructure service requests is slow, complex and expensive. Each request, like a request to host an application whether it’s for dev or testing or production, is treated as essentially a new project with new requirements, architecture review, sizing, etc., even if that same or similar request has been made dozens of times. The resulting process is manual, cumbersome, inconsistent, and often takes several weeks for the end-to-end delivery of the requested service.By comparison, the operating model for cloud computing and infrastructure-as-a-service (or IT-as-a-Service in general) is one that requires on-demand provisioning with standardized options and processes, and rapid elasticity with a shared pool of resources. The graphic here on the right simple highlights those key attributes for cloud computing from the standard NIST definition (the National Institute of Standards & Technology).The cloud operating model means faster, simpler, more flexible and more cost-effective IT. This is what’s so appealing about public cloud computing options like Amazon Web Services. And what we’ve found is that IT organizations can deploy this operating model in a private cloud (and pave the way for a hybrid cloud model), but it requires a new approach to management and data center infrastructure.
Cisco Unified Data Center is founded on a unified, fabric-based design has been developed, from the ground up, to integrates technology silos, reduce costs, and improve productivity. The ideal platform for delivering IT as a Service, Cisco Unified Data Center enables several unique benefits: First, The Unified Data Center architecture unifies and dynamically optimizes compute, storage, and network resources that can be securely and rapidly repurposed and managed on demand to meet the needs of different customers or applications. Through its secure, scalable network fabric—IT organizations can deliver network infrastructure or network services across all types of applications—from legacy applications like Oracle, SAP, and Microsoft Exchange, to new virtualized applications from the likes of VMware, Microsoft, and Citrix. Consequently, you’ll be able to deliver outstanding scalability, performance, high availability across all of your applications. Only Cisco can do this today. Cisco uniquely unifies data centers with the Intelligent Network, via modular, self-integrating computing elements. The network no longer stops at the server—it extends into the server. Through deep integration between the server application environment and the network, security is able to move with the virtual environment. The integration between the network and the data center enables both elements to work as one and deliver a guaranteed experience within clouds, between clouds, and beyond the cloud. The Unified Data Center architecture delivers automated provisioning and management of the shared fabric of compute, network, and storage resources for the delivery of IT services within and between data centers. These new, simplified levels of automation help IT organizations keep pace with rapid change—and deliver new capabilities back to the business—such as self-service, or chargeback functionality. It is the unified approach that allows all of these advantages. Consequently, it only makes sense that the three pillars of Cisco Unified Data Center are: Cisco Unified Fabric , Cisco Unified Computing , and Cisco Unified Management
This diagram depicts the key elements from a management standpoint that are required for IT-as-a-Service, regardless of the business applications and IT services delivered – whether it’s for a dev and test environment for your SAP applications team or a production environment for Oracle database hosting. This framework is similar to the architecture for private cloud recommended by analysts firms like Gartner and Forrester. We’re not trying to replicate all of the existing IT management systems (like your existing service desk / ticketing systems and CMDB) that you use to run your legacy data center environments. Instead, this diagram represents the new capabilities necessary for IT-as-a-Service; the mandatory requirements for this new approach include a self-service portal and orchestration, together with policy-based infrastructure resource management.At the top level of the diagram you have the self-service portal, with on-demand provisioning from a catalog of standardized IT options, governance and approvals, as well as tracking the lifecycle of service usage to prevent sprawl and to enable chargeback or showback. This portal can provide users with a unified online “menu” of options for requesting IT services, whether the infrastructure resources are hosted in your own data centers or potentially sourced externally in a hybrid cloud model.From an automation and integration standpoint, you need to combine the portal with an orchestration engine that can provision the requested service and the underlying infrastructure – with policy-based infrastructure resource management and controls across a shared pool of compute, storage, and network resources, whether physical or virtual.And finally, although IT-as-a-Service demands a new approach, it must complement your legacy systems and management tools. So this new management approach needs to integrate with the existing IT environment for operational processes including monitoring and service assurance, configuration management and a CMDB, as well as business processes like user management in your directory systems and financial management - whether you start with a showback model or evolve to pay-per-use billing and chargeback.
The impact for our customers is taking what was very long and complex legacy management process – that can take weeks for end-to-end, often manual delivery of a request, from the upfront architecture and design of the system to the deployment – to minutes in an automated self-service provisioning environment.And this is exactly what we did at Cisco IT, which deployed Cisco UCS and Nexus – together with Cisco Intelligent Automation for their private cloud.

As customers move from simple uses of the cloud like compute as service to more complex uses,IaaS, and ultimately SP class cloud, there is a safe and sane approach to moving through these use cases. The green arrow shows the evolution of the customer use cases and our prescriptive model for the customer journey that starts first from crawl and then to walk, run and sprint.
Key here is that UCS and Starter Edition provides the best solution for first phases of cloud. UCS and CIAC are better together.
Key here is that successful cloud deployments have in common strict Planning, Project Management and Prerequisite validations. Cloud are complicated and ensure the site preparation (hardware, software and configuration) is ready ensures that the entire implementation can be reduced to 2 weeks for out of the box functionality. Any extra will require additional time and costs.
Bringing the conversation back to the crawl walk run sprint model, this is our recommended pathway for a customer deploying clouds along a safe and sane roadmap. Starting with a basic cloud and moving forward will ensure a successful journey.
