Cloud Computing
Completing the Journey

A virtualized, 10GbE data center provides the foundation for a service-oriented architecture (SOA)- the latest phase in the evolution of IT, otherwise known as cloud computing.

Expanding Business Requirements

Require on-demand access to a shared pool of IT resources

As IT organizations struggle to support ever-increasing demands for performance, availability, and rapid deployment of new applications, the requirement to do more with less remains paramount. Rapidly expanding requirements for storage are driven by unstructured data types, such as text-heavy documents, e-mails, records, and images from the medical and legal industries, as well as vast content repositories containing rich media. New computing paradigms, driven by the need for business intelligence derived from Big Data, stretch compute resources. Exacerbating these problems are the complexities of many IT environments, for example: dealing with rapidly changing business models, the need to support mobility, and data security regulations across a global landscape, along with the maintenance of legacy systems. This situation has led to the introduction of utility-like solutions for IT that extend data center capabilities beyond virtualization and converged networking by enabling on-demand, elastic access to a shared pool of IT resources in the cloud.

Benefits of a Service-Oriented Infrastructure

Enhance performance and flexibility, while reducing costs

Enterprise data center administrators, confronted by these new business challenges, increasingly focus on improving asset utilization to enhance performance and flexibility, while reducing costs. The promise of cloud computing enhances this premise with a service-oriented operational paradigm featuring high efficiency, elastic scalability with the ability to react to on-demand resource requirements in near real-time, fast and easy deployment of new applications, increasing responsiveness and agility of IT as a whole, and lower overall cost to the business.

QLogic Data Migration Solutions for Cloud Enablement

Perform non-disruptive data migrations in heterogeneous environments

As applications shift to cloud computing infrastructures, IT managers are challenged with migrating data from one data center to another without disrupting the business. Because most data centers are a blended mix of legacy hardware and software combined with new technology from many vendors, IT managers are looking beyond traditional host- and array-based data migration tools to perform non-disruptive data migrations in these heterogeneous environments. The QLogic Data Migration Solution (DMS)—based on the high-performance family of iSR62xx multi-protocol routers as the data migration engine—is the most flexible tool on the market. QLogic's DMS provides IT managers with a single tool to migrate data from the most complex data center environments with heterogeneous storage, multi-vendor fabrics, multi-protocol networks, and operating systems into the cloud. The combination of lower cost, smaller data migration windows, enterprise-level high availability, support for heterogeneous environments, and advanced capabilities such as thick-to-thin provisioning and data scrubbing are the reasons customers choose QLogic for their data migration solution.

Cloud-Based Offerings

Distinguished by three service models

Infrastructure as a Service (IaaS). IaaS applications are solutions for IT’s resource provisioning, configuration, and management functions (compute, storage, network, security, reporting, and so forth). They provision compute, storage, network, and other fundamental computing resources from which the user can deploy and run arbitrary software, including operating systems and applications. The user does not manage or control the underlying cloud infrastructure, but has control over the service-offered environment, potentially including operating systems, hypervisors, storage, deployed applications, and possibly limited control of select networking components.

Platform as a Service (PaaS). PaaS applications are solutions targeted at software development and testing, which are used by IT as well as Engineering (R&D) in software development companies. With PaaS, the user can deploy onto the cloud infrastructure user-created or acquired applications, which were created using development environments, programming languages, and other software development tools supplied by the service provider. The user does not manage or control the underlying cloud infrastructure, including network, servers, operating systems, or storage, but has control over the user deployed applications and possibly application hosting environment configurations.

Software as a Service (SaaS). SaaS applications are solutions for general business process functions, including sales, finance, marketing, and other general business functions (such as e-mail and collaboration applications), as well as consumer-focused applications such as social media sites, location-based mobility applications, and app stores. With SaaS, users access the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface, such as a Web browser (for example, Web-based e-mail). The user does not manage or control the underlying cloud infrastructure, including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Cloud Services Characterizations

Three distinct deployment methods

  • Private cloud. The cloud infrastructure is operated solely for a specific organization. It can be managed by the organization or a third party and can exist on or off premises.
  • Public cloud. The cloud infrastructure is made available to the general public and large industry groups and is owned by an organization selling cloud services.
  • Hybrid cloud. The cloud infrastructure is a composition of two or more clouds (private or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (for example, cloud bursting for load-balancing between clouds).

Cloud Enabling the Enterprise

Integrate your enterprise with cloud-based services

Realizing the flexibility and agility of a virtualized and converged network infrastructure in your existing environment not only provides tangible benefits in their own right, but readies your enterprise to integrate with these cloud-based services. For example, for private clouds offering IaaS, all components logically reside within the firewall of the served organization. The infrastructure is either implemented internally by the IT department or delivered as a managed service by a cloud provider. Behind the security of the firewall, a private cloud implements high levels of automation to virtualize the infrastructure, including servers, networks, and storage, to deliver on-demand and elastic services. With private cloud, security of the data and operational performance still need to be determined and monitored by the IT team, and requirements for high-quality Service Level Agreements (SLAs) remain intact. In addition, as more applications shift to cloud computing infrastructure (IaaS), IT managers are challenged with migrating data from one data center to another without business disruption. Private clouds can deliver services internally to employees or business units through an intranet or over the Internet via a Virtual Private Network (VPN), extending on-demand services to remote locations. In both cases, private clouds leverage existing infrastructure to deliver and charge-back for bundled or complete services from within the privacy of the organization's network. For data centers beginning to implement cloud-computing strategies, QLogic host connectivity solutions featuring Converged Network Adapters, Intelligent Ethernet Adapters, and Fibre Channel Adapters are key enablers to achieving the benefits of a private cloud-based IaaS cloud computing implementation.
