Hybrid Cloud Modernization – For largest Parcel Services company in the world

What?

Benefits• Mainframe application modernization with Azure refers
to the process of integrating mainframe workloads withapplications/services on the Microsoft Azure cloud
platform. By doing so, businesses can take advantage ofthe benefits of the Azure native-cloud features, such as
greater flexibility with Azure DevOps, scalability, API
enablement, cost savings and integration with advanced
services like IoT and ML etc.

• Increased agility, innovate faster, speed to market with
Modern DevOps tools/services.

• Mainframe offers multiple ways to provide seamlessintegration with Azure e.g. Cloud modernization stack ,IBM Z Digital Integration Hub, z/OS Cloud Broker , IBM z
Virtual test platform etc.

• Lower infrastructure costs with greater ROI throughAzure Infrastructure as service.

• Azure on the other hand, offers various cloud-native
tools/services that can be easily integrated withMainframe provided tools e.g. Azure API management,Azure DevOps, Azure Clusters, Azure Even Hubs, Azure
Data Factory etc.

• Increased Security with Azure features - network
isolation, encryption, access control, certificates etc.

• Single integrated operating model with hybrid cloudstrategy.
• Interoperability of applications across Azure and onprem.

• Increased scalability.

• Increased Resiliency with multi-region and zone-based
deployments, automated backups and DR processes.

• Integration with Azure managed cloud-native services
and capabilities enable new use cases.

Azure DevOps for z/OS Applications
Accelerate agility on the mainframe by providing consistent development
experience on Azure using modern tools that are familiar to all developers.

• Reduced needs for specialized skills with commonand familiar tools• Deliver application changes faster for existing

COBOL, PL/1, Java , or Assembler programs• Integrated with Azure DevOps pipeline driving

enterprise-wide standardization and consistency• Self-service access to z/OS environments andresources for application development on Azure• Leverage new programming languages including

python, Node.js and Go that run on z/OS platformSimple & Secure access from Digital Channels using APIs
Capability to create industry standard and secure RESTful APIs enabling
Azure digital assets to quickly integrate with mainframe apps and data

• Make mainframe (z/OS) applications and data available

to applications running on Microsoft Cloud• API Developers working on Azure can create industry

standard APIs for mainframe applications in minutes• Low code API creation using IBM Z & CloudModernization Stack• Scale business critical REST APIs and seamlessly

manage using API gateways on Microsoft Cloud• Flexible, containerized deployment model – host yourAPIs on z/OS or directly on Azure

Real-time sharing between z/OS applications & AzureProvides near real-time access to z/OS data with IBM Z DigitalIntegration Hub that are accessible via Kafka, JDBC, or REST APIs

• Selectively curate and share mainframe information withMicrosoft Azure applications.

• Reduce latency with high-performance environment• Surface information through standards interfaces,

including Kafka, JDBC, and REST APIs

• Microsoft Cloud services can access near real-time

information on the mainframe without impacting OLTP

Share real-time
information between z/OS
applications and Azure

Optimized sharing of real-time core businessinformation with cloud applications on Azure• IBM Z Digital Integration Hub optimized sharingof real-time core business information with cloud
applications on Azure• Curate & share necessary information as opposed
to moving all the raw data — resulting in optimal
performance• Interact with in-memory caches on z/OS for handlingrequest to and from Azure applications — resultingin faster cloud application development• Surface information through standards-based
interfaces, including event-based mechanisms suchas Kafka, JDBC or open standard-based REST APIs
• Azure application services can access real-time
intelligible/consumable information and events withlittle to no impact on core application environments
