Mainframe modernizationwith Kyndryl ManagedExtended Cloud Infrastructureas a Service for IBM ZUse the modern mainframe as a cornerstone for buildingthe infrastructure that enables your journey to hybrid cloud

Highlights– Modernize infrastructureto get the most fromyour mainframe– Enable a culture changeat the heart of your journeyto hybrid cloud– Rely on zCloud to provideIBM Z computing powerusing a security-rich,scalable cloud modelAt Kyndryl , we are committed to the concept thatmainframe modernization is not about moving all yourworkloads and applications off of the high-performing,security-rich and highly available IBM Z platform—it’sabout using the capabilities of every platform in the hybridcloud to host each application based on unique availability,performance, security, resiliency and other requirements.The modern hybrid cloud ecosystemMainframe modernization efforts require enterprises withmainframes to keep modern solutions—like IBM Z—at thecenter of their hybrid cloud strategy. Hybrid cloud is aboutmore than just re-platforming and going from one monolithicenvironment to another. The modern mainframe is designedto be open, supporting not just traditional workloads but alsocloud-native applications that were built using languagesfamiliar to developers on all platforms that can be implementedas microservices in containers.Kyndryl Managed Extended Cloud Infrastructure as aService for IBM Z—also known as zCloud—uses a clouddelivery model to provide you with access to a scalable,multitenant infrastructure that is designed for flexibility andadaptability. You have your choice of several operating systems,including IBM z/OS , Red Hat Enterprise Linux or other Linuxplatforms, and the latest versions of standardized softwarestacks to facilitate flexibility. zCloud can also support otherIBM software as well as independent software vendor (ISV)software on a custom basis. Capacities for compute, storageand virtual tape are scalable to meet your enterprise’sunique needs.You can use Red Hat Enterprise Linux and the containercapabilities of Red Hat OpenShift Container Platform (OCP)for development in place. Combining these solutions withproducts like z/OS Connect to expose traditional mainframemiddleware and data through APIs facilitates integration.Co-host these solutions on the same mainframe for fastnetworking and near-zero latency. Additionally, you cancreate microservices in containers on virtually any platformand integrate them to create consistency and drive agility.Culture change is at the heartof mainframe modernizationThe hybrid cloud, including the modern mainframe, can bemanaged consistently at the infrastructure and platform levelusing common and open tools. This support integrates intoyour enterprise’s overall DevOps or DevSecOps processes.Striving toward agile processes is a necessary culture changethat is at the heart of successful mainframe modernizationsand hybrid cloud journeys.2

The right platform for the right workloadsKyndryl provides many options for hosting and managing yourIBM Z and LinuxOne environments. We can support you whereyou are in your data center or in one of our purpose-built datacenters. You can choose a dedicated server model or accelerateyour journey to hybrid cloud with zCloud. Either way, we provideIT management expertise, deep experience with IBM Z, usingtried-and-tested virtualization technology to deliver a security-rich,highly available mainframe IaaS platform that can redefineIT efficiency, cost and agility.Reduce costs with IBM Zand managed serviceszCloud can help you reduce costs, making funding availablethat you can redirect toward other modernization initiatives.This financial efficiency helps reduce or even eliminate thecapital and overall expenditures associated with running yourown data center, such as hardware, floor space, power andcooling costs. Our IaaS solution can also help you rationalizeyour software portfolio and offers predictable consumptionbased pricing with monthly billing to help you manage costs.Consolidating Linux workloads from distributed systems andplatforms to IBM Z can also reduce complexity and help yousave on software licensing costs—yielding you additionalfunding for modernization and other business-critical projects.Our fully managed services are designed to provide end-to-endmanagement and monitoring, backed by the experience ofthousands of mainframe specialists located around the world.Kyndryl uses innovative technologies, effective tools andprocesses, and automation to help prevent problems in yourenvironment before they occur. Kyndryl mainframe specialistsfor service delivery can also remove the challenge and costof hiring and retaining talent with this increasingly scarceskillset, allowing your staff to focus on other areas of innovation.Using open solutions like Zowe or other integrated, graphicaluser interface (GUI)-based tools, we can also help boostproductivity in your non-mainframe personnel by reducingthe need for in-house knowledge specific to IBM Z.Company ACompany BCompany CApplicationApplicationApplicationPublic cloudCompany ux† onLinuxOneIBM Cloud Company BMemoryMemoryMemoryCPUCPUCPULPARLPARLPARCompany C(mirrors IBM Z environment)Disk subsystemsTape subsystemsInput and outputRed Hat and other Linux†Figure 1.

Support high availability and securitywith mature service designThe zCloud mainframe capacity we provide and manage ishoused in purpose-built, highly resilient and security-rich datacenters around the world. Our LPAR-based model is designedto offer the highest levels of security with the system achievingEvaluation Assurance Level 5 (EAL5) accreditation. Additionalsubsystem isolation helps protect your data, applications, testand production environments. The solution is designed to enableend-to-end encryption, including for virtual tape, storage andin-flight data across the network. For additional access controls,IBM Z is supported by robust security management productsfor mainframes, including IBM Resource Access Control Facility(RACF), CA Top Secret and CA Access Control Facility (ACF2),all of which are complemented by Kyndryl’s deep security domainexpertise. And as a data processor that’s designed to be completelycompliant with the General Data Protection Regulation (GDPR),Kyndryl and zCloud can help enable enhanced data privacy.Kyndryl can also work with you to apply the appropriate enterprisegrade security processes, systems, networks and tools to helpsupport your specific compliance needs, such as Payment CardIndustry (PCI), Health Insurance Portability and Accountability Act(HIPAA) and Federal Financial Institutions Examination Council(FFIEC) requirements.Additionally, Kyndryl offers configurable options for high availabilityso that we can accommodate both critical and noncritical businessapplications in a cost-effective manner. zCloud offers configurableoptions beyond the standard options for z/OS including Hot Standbyand High Availability with service-level agreements (SLAs) up to99.999%. With each option, you choose the server, disk and virtualtape storage resources that you need (see Figure 2). For Red HatEnterprise Linux, the standard option is sufficient to meet most clientrequirements, but Kyndryl can satisfy custom Linux requirementsas well. A carefully scheduled maintenance and update programfurther supports platform resiliency.Extending the capabilitiesof IBM Z to the hybrid cloudKyndryl can support you in your hybrid cloud journey. Our supportis designed to be integrated across any platform—whether thatbe all on IBM Z or through standard connections to the other hybridcloud platforms for applications better suited to other platforms.ISVIBM CICS IBM IMS Softwarestacks†IBM DB2 Server service types†BaseDiskTapeHot standbyHighavailabilityFlash copyMetro mirrorzCloudrecoverysite withtape andmirror optionsStorage service types†BaseTape service types†Basevirtual tape†Globalvirtual tapeCheck for feature availability in your country.†Figure 2.
