Hybrid Cloud:FutureArchitectureDocumentTitleThegoeshere ReadySourceReferenceSans Pro Regular9pt for Modern BusinessGet future ready - Modernise nowNo industry was prepared for the disruptionCOVID-19 caused. Although some organisationswere able to act more quickly than others to supportremote workers and sustain business operations,even those wit sophisticated digital capabilities facedchallenges with scalability and interrupted supplychains.As a result, businesses across industries had toswiftly pivot to build new digital competencesif they wanted to not only survive but compete.Today, they’re accelerating digital transformationinitiatives despite economic uncertainty. They’removing beyond simply responding or adapting, toaccelerating innovation so they can seize any newopportunities that arise.And to achieve all this, they’re modernizing bothapps and infrastructure while moving to the cloud.App modernisation drives digitaltransformationApp modernization makes it possible for enterprisesto continuously change and improve applicationsat a pace that keeps up with their rapidly shiftingbusiness needs.This usually involves using container technology.Containers allow enterprise developers to deployapplications using portable, lightweight packaging.App modernization also includes using the cloud toachieve programmatic control of infrastructure, bothvirtually and remotely. It is the combination of bothpackaging and on-demand infrastructure servicesthat allow developers to use Agile developmentpractices and automated release processes toquickly and frequently update application features.Kubernetes is a popular choice for automatingdeployment to production and orchestratingcontainer run time at scale to achieve highavailability.dimensiondata.comIn combination,containers, cloud andKubernetes make itpossible for developersand IT work together tomeet digital businessrequirements.Cloud brings it all togetherModern apps require modern infrastructure. Andfor most organizations, that means adopting hybridcloud infrastructure. And it’s not just about efficiencyand scale; it’s about changing the way that IT servicesare delivered and consumed, with flexibility todeploy workloads where it makes sense from bothbusiness and technical requirements.This white paper explores how a hybrid cloudties together IT elements as a cost-efficient andproductive strategy. It provides a referencearchitecture detailing all of the necessary layers.With this information, your team can deliverstandardized, on-demand services that areplatform- and environment- ndependent, and deliverdeveloper-ready infrastructure services for all typesof applications to not only withstand whateverhappens next, but turn it into competitive advantage.

Document Title goes here Open Sans Pro Regular 9ptHybrid Cloud Reference ArchitectureHybrid cloud is the optimal model for modern business, and is the preferredenvironment for the vast majority of today’s IT organizations. According toEnterprise Strategy Group, 88 percent of enterprises currently have a hybridcloud environment—a number that will continue to rise in the next 12 to 24months.1Hybrid cloud is defined as a combination of on-premises data center, cloud,and edge IT environments that have been unified to support consistentoperations. It’s important to understand that cloud is an operating model thatcan utilize either public or private cloud infrastructure. Although 70 percent ofIT organizations recently surveyed are actively engaged in migrating existingapplications to public cloud, they are also planning to deploy nearly half (47percent) of their new cloud-native workloads to private cloud.2But the hybrid cloud infrastructure is just the beginning. You need othercapabilities layered on top of it: application operations, IT service delivery, andoperational efficiency.You need these to enable: Rapid application delivery and observability Flexible consumption of IT services Consistent operationsThe reference architecture in Figure 1 illustrates key capabilitiesdelivered by a singleplatform hybrid cloud solution.dimensiondata.com Copyright Dimension Data 31.

Hybrid Cloud: The Future Ready Reference Architecture for Modern BusinessApplication delivery and observabilityConsistent operationsAt the top level of the reference architecture—theapplication operations level—your organization needsthe ability to swiftly make a broad spectrum of changes toapplication operations. Specifically, you need to be able to:At the operations layer of the hybrid cloud referencearchitecture, your organization can deploy a single cloudoperating model for securing, governing, and operatingthe entire hybrid cloud. This is where you benefit from thesignificant efficiencies of extending a single, proven modeleverywhere because you have: Rehost – Perform “as is” workload migration to thecloud without changing architecture or code Replatform – Be able to containerize traditionalworkloads to increase agility and standardizeautomated development and deployment tool chainsStandardized services – A single model for security,governing, and operating the entire hybrid cloud Refactor – Utilize cloud-native and microservicesarchitectures by rewriting or writing new code.Automated service delivery – Greater agility andproductivity, and the elimination of operationalbottlenecks created by legacy infrastructure Optimized infrastructure and resource utilization– The ability to get more out of your existinginvestments in teams, processes, policies, and skills byextending to the cloudFlexible consumptionAt the IT service delivery layer, your team needs to be ableto optimize infrastructure by leveraging the instant agilityand scale of public cloud providers while using familiartools and processes. This leads directly to: Self-service – Your developers and line-of-businessapplication owners can access resources from bothon-site and public cloud environments with the cloudself-service delivery capabilities and programmatic APIinterfaces they have come to expect.Strong governance – With hybrid cloud, you can linkpolicies to each application which ensures consistentadoption wherever workloads are deployed andmanaged.Reduced costs – Your organization can improveon-premises cloud capabilities and shift from siloedinfrastructure-oriented operations to a service-brokercapability that delivers the same interactions with IT,regardless of where applications are deployed. Thisdrives efficiencies of scale and thus lower costsdimensiondata.comConsistent infrastructureFinally, at the infrastructure layer, your organizationcan leverage a cloud operating model that is based on astandardized solution stack across multiple environments.No retraining or retooling required because the hybridcloud infrastructure is: Software-defined – Bringing siloed resources togetherinto a holistic, software-defined system allowsconsistent operations through a single managementinterface Automated and orchestrated – Streamlining andstandardizing service delivery makes IT both moreagile and efficient Flexible deployment – With options for on-premises,hosted provider, and public cloud— with softwaredefined and automated control of all underlyingresources Copyright Dimension Data 4

Hybrid Cloud: The FutureReady Referencefor ModernBusinessDocumentTitle goesArchitecturehere Open SansPro Regular9ptHybrid Cloud Supports Strategic IT InitiativesA single hybrid cloud operating model builds on existing, proven capabilities for supporting the most demandingand essential applications in the world. It also enables your organisation to tap into powerful emerging ITinnovations. Here are some ways that one platform for hybrid cloud can advance your strategic initiatives while alsoenabling your organisation to get the most out of your existing IT investments.Modernise your data center with cloudMassive opportunities still exist for your IT organisation to improve the capacity, efficiency, and operations ofyour on-premises data center(s). By extending proven virtualisation to storage and networking, and managinginfrastructure resources together (rather than in silos) your organisation can create complete software-defined datacenters that reduce IT complexity. Hyperconverged infrastructure (HCI) significantly improves resource efficiencyand makes resources more easily consumable. By adopting a hybrid cloud operating model, you quickly transformtraditional IT offerings into as-a-service ones through service blueprinting, self-service, and rich APIs for developers,further increasing IT agility.Tap into public cloudsAlthough cloud strategies initially involved migrating a target percentage of on-premises applications to the cloud,today’s hybrid cloud strategies are more nuanced. A hybrid cloud extends your cloud model to traditional IT,delivering: Pay-per-use pricing by linking on-going costs to operational expenses (OpEx) instead of capital expenses (CapEx At-scale service delivery for temporary but resource-intensive use cases Data center consolidation or evacuation App development in cloud, app production on premises Cross-environment disaster recoveryAutomate your service deliveryAutomated service delivery is the hallmark of cloud, reducing IT burdens and speeding your operations. With hybridcloud, you transform how IT services are consumed because automation streamlines and standardizes servicedelivery.Automate service consumption with developer-ready infrastructureWith hybrid cloud, your team can ensure developer-ready infrastructure can be automatically consumed as cloudservices as part of DevOps, Agile, and CI/CD methodologies. Additionally, you can enable abstraction and APIinterfaces for programmatic consumption of infrastructure services in a way that powers faster and more frequentdevelopment of new app features.Modernise your appsModernising infrastructure and applications accelerates the speed and ease of developing new apps as well asupdating existing ones. Through containers, your developers can deploy their applications with portable, lightweightpackaging while hybrid cloud gives them programmatic control of infrastructure both virtually and remotely. Thecombination of containers, cloud infrastructure, and integrated CI/CD, tools allows your developers to ship rapidincremental changes to applications to meet continuously changing business needsEmbed securityAlthough seamlessly scaling applications between data centers and cloud has immense advantages, securing hybridsolutions is increasingly complicated. And more so for organizations that try to secure applications by “bolting on”multiple point security products that solve niche problems. A future ready hybrid cloud embeds security intrinsicallyinto the infrastructure, enabling your IT organization to apply security policies that follow workloads, and are notlimited to infrastructure boundaries. This ensures your security policies scale with applications as they extend fromthe data center to the cloud or to the edge.dimensiondata.com Copyright Dimension Data 5
