A multi-cloud world is quickly becoming the new normal for many enterprises. But embarking on a cloud journey and managing cloud-based services across multiple providers can seem overwhelming.
Even the term multi-cloud can be confusing. Multi-cloud is not the same as hybrid cloud. The technical definition of hybrid cloud is an environment that includes traditional data centers with physical servers, private cloud with virtualized servers as well as public cloud provisioned by service providers. Quite often, multi-cloud simply means that an organization uses multiple public clouds from many vendors to deliver its IT services. In other words, organizations can have a multi-cloud without having a hybrid cloud, or they can have a multi-cloud as part of a hybrid cloud.
As organizations begin to adopt public cloud, one element of consideration is what to do with existing applications. These applications were not built with cloud in mind, though most are virtualized today. These organizations must now determine a modernization strategy for these applications and incorporate how public cloud might fit into the picture. This paper examines the use of public cloud for data center extension and replacement, particularly in light of existing traditional enterprise applications. It also looks at the role of VMware's vCloud Air public cloud service in meeting the needs of these applications.

This white paper from Microsoft discusses the underlying economics driving the transition from mainframe to client/servers. The economics of the cloud, by using in-depth modeling, is also reviewed to better understand the long-term IT landscape.
Merchants and service providers that process credit card payments must comply with the Payment Card Industry Data Security Standard (PCI DSS), now at Version 3.0. Whether the transaction occurs in a store or online, and regardless of the environment, from physical Point of Sale devices, to virtualized servers, or web servers in a public cloud, PCI DSS 3.0 mandates that these organizations are responsible for the security of their customers’ cardholder data. Read this white paper to learn more about the Payment Card Industry Data Security Standard 3.0.

NoSQL databases are now commonly used to provide a scalable system to store, retrieve and analyze large amounts of data. Most NoSQL databases are designed to automatically partition data and workloads across multiple servers to enable easier, more cost-effective expansion of data stores than the single server/scale up approach of traditional relational databases. Public cloud infrastructure should provide an effective host platform for NoSQL databases given its horizontal scalability, on-demand capacity, configuration flexibility and metered billing; however, the performance of virtualized public cloud services can suffer relative to bare-metal offerings in I/O intensive use cases. Benchmark tests comparing latency and throughput of operating a high-performance in-memory (flash-optimized), key value store NoSQL database on popular virtualized public cloud services and an automated bare-metal platform show performance advantages of bare-metal over virtualized public cloud, further quant
Find out how private clouds deliver unprecedented flexibility and economies of scale by leveraging the speed of virtualization and preparing you to federate applications across internal or external IT resources. EMC Consulting can help you to quickly seize these benefits by deploying a private cloud strategy.
So far, most data centers have virtualized their least-critical workloads as a matter of basic cost containment. Virtualizing mission-critical applications is still forthcoming for the majority,though, largely due to infrastructural concerns. Complicating matters is the shift in IT purchasing decisions from IT to business management.
Integrated Computing Platforms (ICPs), private cloud computing, and public cloud services all leverage virtualization to achieve a number of IT and business goals, including increased ROI, reduced OpEx, and business process improvement. Now more than ever, it makes sense to explore the benefits of ICPs.

Gordon Haff - Senior Cloud Product Manager, Red Hat
You can build a private cloud today in an evolutionary way that makes use of and integrates with technologies that you already own. Proceed at your own pace and maintain strategic flexibility for the future using infrastructure products that provide a robust, enterprise-class environment that is consistent across bare metal, virtualized servers, private clouds, and public clouds. The steps are all thoroughly documented in a reference architecture, and can be augmented with additional Red Hat products and services as needed. In this session, Gordon Haff will take you through the steps.
Virtualization is helping organizations like yours utilize data center hardware infrastructure more effectively, leading to a reduction in costs and improvements in operational efficiencies. In many cases, virtualization initiatives begin internally, with your own hardware and networking infrastructure augmented by tools like VMware® or Linux® KVM and OpenStack® to help manage your virtualized environment. Often referred to as private cloud, these projects are fueling significant expansion into what can be referred to as the public cloud.
