Mainframe and midrange migration

Reduce costs by bringing your midrange and mainframe applications to an agile cloud platform.

Ensure success with a reliable and scalable mainframe to cloud migration strategy

Modernize the mainframe and midrange applications you rely on by running them on Azure. Rapidly address your company's needs at scale using midrange and mainframe to cloud migration tools and services without sacrificing functionality, security, or compliance.

Azure Kubernetes Service (AKS)

Reduce costs and free up your budget to support digital transformation by migrating midrange and mainframe applications from expensive legacy systems to Azure. Save on hardware, software, and management of these platforms. Save even more by implementing business continuity, disaster recovery, or scalable solutions. With Azure, you pay only for consumption, not for the systems required to support these requirements.

Application services

As legacy programmers retire, it's becoming difficult to find talent who know how to use legacy development tools to maintain legacy applications. By moving midrange and mainframe applications to the cloud and using modern development tools such as Eclipse and Microsoft Visual Studio, you'll expand the talent pool with new developers who can collaborate with legacy developers to continue evolving legacy applications.

Data services

Accelerate updating and deploying legacy applications by moving from a legacy waterfall development process to a modern DevOps environment. Instead of waiting six months or more to deploy a major update, deploy incremental, daily updates to support business requirements.

Machine learning

Legacy applications are limited to running on legacy platforms in the datacenter. Use migration tools and services to move these legacy applications to an x86 platform and take advantage of the cloud for running your mission-critical workloads.
