Sizing Cloud Bringing cloud benefits to business-critical workloads

WHITE PAPER Sizing Cloud Bringing cloud benefits to business-critical workloads Introduction Cloud is rapidly becoming the solution of choice to address a host of enterprise issues from increasing agility and efficiency to supporting a mobile workforce to bringing new products and services to market. But it is essential for organizations to adopt the right cloud model to support present and future requirements. With its dedicated cloud practice, Redapt brings expertise in planning, deploying, and managing cloud. Our cloud solutions power banks, hospitals, aerospace companies, defense contractors, online retailers, fast-paced gaming companies, large hosting providers, and other organizations where performance and security are business-critical. Rapid responsiveness is now a key success factor for many organizations from finance to social media. IT procurement cycles are often unable to support the pace of innovation required to deliver new services, scale on-demand, and compete. With cloud, virtual platforms can be acquired and applications deployed very quickly. Applications can be designed to scale up or down based on usage requirements. And, organizations can develop their own cloud-aware applications to support new business processes or software as a service (SaaS) offerings. The Redapt team are complete rockstars! They have become one of our top go-to partners for everything from our own infrastructure requirements to building some of the best Joyentbased private and hybrid cloud deployments for our customers around the world. CTO and Co-founder, Joyent Here, we ll look at some of the key cloud decision points and usage models to consider as you assess your cloud options. Redapt Private Cloud Redapt private cloud solutions are designed to provide the advantages of cloud, without the risks a public cloud can bring. Each private cloud solution is customized to your specific compute, network, and storage requirements; current infrastructure; and growth plans. 1

Redapt will deliver cloud to your organization in the way that works best for you. Designing a configuration based on industry-leading components and a foundation of reliable, robust Intel architecture begins with a thorough assessment of your requirements. We will then deliver and deploy your cloud solution onsite. Options include starting small with a pilot implementation, training your administrators and IT staff, and 24/7 remote management. Once delivered to your datacenter, your cloud can be online and serving your organization in as little as 30 minutes. Scalability is a core component of Redapt s cloud offering. Once deployed, your cloud infrastructure can be quickly and cost-effectively expanded or sized as your needs evolve. Public cloud services can also be provisioned to meet fluctuating demand. Why Choose Private Cloud Public Cloud Private Cloud Cost Factors Utility Model: Public clouds typically deliver a pay-as-you-go model, where you pay by the hour for the compute resources you use. This is an economical way to go if your utilization of resources varies widely and is unpredictable. No Contracts: The utility model means you only pay by the hour. If you want to shut down your server after only two hours of use, there is no contract requiring your ongoing use of the server. Better ROI: At scale, the ROI for private clouds is significantly better than public clouds. And, you get to take advantage of the steady increases in processing power provided by Intel processors. For instance, new servers with the Intel Xeon processor E5 v2 product family boosts your general computing perfor-mance by up to 240% 1,2 or your technical computing performance by up to 480% 1,3 when compared to a typical 4-year-old server. Security Factors Shared Hardware: Because the public cloud is by definition a multitenant environment, your server shares the same hardware, storage, and network devices as the other tenants in the cloud. Security: Because private clouds are dedicated to a single organization, the hardware, data storage, and network can be designed to assure high levels of security that cannot be accessed by other clients in the same datacenter. 1:1 virtualization and bare-metal provisioning possible in private clouds can further enhance both security and performance. Compliance: Because the hardware, storage, and network configuration is dedicated to a single client, compliance is much easier to achieve. Manageability Factors Tools: An array of tools to operate public cloud resources are available, but most solutions drive public cloud adopters to implement new tools rather than extend existing tools they may have in-house for existing infrastructure. Customizable: Hardware, network, and storage can all be specified and customized in the private cloud. Solutions to unify management of private cloud and virtualized infrastructure resources are available. 2 Performance Factors No Control of Hardware Performance: In the public cloud, you cannot customize the hardware, cache, or storage performance (SATA or SAS). Your virtual server is placed on whatever hardware and network the public cloud provider designates for you. And frequently, there is no transparency into the hardware that your workloads are running on, making it very hard to evaluate cloud providers and the actual performance that you will get. Performance also varies depending on the demands of other tenants assigned to your cloud. In heterogeneous, hardware-based multitenant, public cloud environments, performance can vary between 40 and 60 percent. 4 Optimized: Implementing dedicated, highperformance servers for demanding applications is possible in private clouds. The best of both worlds is enabled through a hybrid cloud deployment.

Cloud ROI Though dependent on the type of deployment and organization, Redapt is seeing a return on investment for replacing public with private cloud in 9 20 months. Interestingly, there is an inflection point for public cloud where usage grows past a certain level and where public cloud costs begin to exceed costs of an equivalent or higher quality private cloud. In addition, private cloud implementations often deliver 2 6x performance increases when architected with increased processing power and I/O. 5 Public cloud provides great general purpose infrastructure, but for I/O intensive applications, public cloud resources often offer lower performance in standard offerings (or are cost-prohibitive with specialized offerings) compared to the optimized hardware selected for a private cloud. For applications with high I/O utilization in the persistent storage layer, consolidation rates of six public cloud instances to one private cloud instance are possible. Similarly, with the latest Intel processors, CPU-intensive applications deployed in the private cloud can benefit from twice the performance of many public cloud offerings. An added benefit for those implementing private cloud is the ability to design more fault tolerance in the private cloud hardware. This can provide improved reliability compared to public cloud capabilities. Server consolidation further reduces infrastructure footprint and energy costs, while simplifying application management.

For example: Irregular and extreme workload patterns are ideal candidates for movement to the public cloud. Irregular patterns represent potentially low utilization of expensive capital. Extreme workloads can be a worst case scenario. For example, addressing the demand from a successful product launch. We re an end-to-end solutions provider to get you from zero to cloud. Our continuous investment in internal reference architectures on reliable and scalable solutions helps us do this very quickly, while adapting to your unique requirements.

These diagrams provide a quick reference for categorizing workload balance. On and Off Growing Fast Compute Average Inactivity Period Usage Compute Average Usage Time Time On and Off This describes seasonal or time-bound workloads where processing requirements veer from all to almost nothing. Important enterprise workloads, including those that are run monthly, quarterly, and annually, exhibit this type of behavior. Growing Fast This can impact smaller startup companies or workgroups in larger companies or be associated with new development. Planning needs to happen during both development and operations. Elasticity can be a huge opportunity for savings. Unpredictable Bursting Predictable Bursting Compute Average Usage Compute Average Usage Time Time Unpredictable Bursting Here, an occurrence triggers heavy usage requirements. Normally, you would have to prepare by scaling design considerations to try and predict what this requirement could be. This may be one of the worst cases for which to plan: consider an emergency response system for which normal operation is fairly well understood. Then a hurricane hits, and just when you most need the system, it gets overwhelmed. Predictable Bursting Think Super Bowl Sunday. Most of the year or days of the week, demand is much less. Even though the additional load is expected, it s expensive to maintain this capacity because it s underutilized when demand is lower. Types of Cloud Services Cloud solutions utilize automation, orchestration, and virtualization to manage and serve operating systems, data, and applications. Redapt private cloud solutions typically follow an infrastructure as a service (IaaS) model. This will take into account your workload requirements, such as I/O, latency, and analytics, while providing a fully packaged, private cloud solution based on industry-leading Intel Xeon processors and hosted at your location of choice.

For example, based on your specific needs, Redapt cloud configurations can be designed to meet the following requirements: Federal Information Security Management Act (FISMA): Redapt enables U.S. government agency customers to achieve and sustain compliance with FISMA. The act requires federal agencies to develop, document, and implement an information security system for its data and infrastructure based on National Institute of Standards and Technology (NIST) requirements. Authorization and accreditation requires PCs to implement and operate an extensive set of security configurations and controls, and includes documenting the management, operational, and technical processes used to secure the physical and virtual infrastructure, as well as a third-party audit of established processes and controls. Payment Card Industry (PCI) DSS Level 1: Level 1 service provider under the PCI Data Security Standard (DSS). Merchants and other service providers can now run their applications on Redapt s PCI-compliant technology infrastructure for storing, processing, and transmitting credit card information in the cloud. Other enterprises can also benefit by running their applications on other PCI-compliant technology infrastructure. ISO 27001: This is a widely adopted global security standard that sets out requirements and best practices for a systematic approach to managing company and customer information based on periodic risk assessments. In order to achieve the certification, a company must show it has a systematic and ongoing approach to managing information security risks that affect the confidentiality, integrity, and availability of company and customer information. Federal Information Processing Standards (FIPS): The FIPS Publication 140-2 is a U.S. government security standard that specifies the security requirements for cryptographic modules protecting sensitive information. To support customers, Redapt cloud configurations can be designed to meet FISMA, PCI, ISO 27001, and FIPS requirements. 6
