What you'll learn

After this course, a thorough understanding and approach towards Modernizing Enterprise workloads in Mainframe will be obtained.
I have also added content for IBM Power in the description, while the coverage of IBM Power is minimal, we can also double click on IBM Power as a technology
A new description has been added on new IBM z solutions and IBM Power solutions
This includes IBM Power Virtual Server, IBM Bob for z and i and many more.

Course content

1 section • 9 lectures • 1h 17m total length

Introduction6:53
Explore how to turn mainframe assets into digitally accessible workloads, align with CIIC and testing, and deliver a prescriptive modernization roadmap.
Modern Mainframe Best Kept Secrets - Part A15:01
Unearth modern mainframe best kept secrets and practical modernization options, from exposure via services and specialty processors to COBOL-to-Java migration, SDLC automation, and analytics acceleration.
Modern Mainframe Best Kept Secrets - Part B4:42
Explore mainframe modernization strategies, including offloading data to cloud ecosystems and using Apache technologies for analytics. Learn how to select workloads, enable APIs, and integrate DevOps for real-time COBOL workflows.
How to Modernize your Mainframe15:01
Explore how to modernize your mainframe by incrementally migrating COBOL to Java, migrating data to databases, exposing services via API-enabled interfaces, and optimizing workloads and costs to boost business agility.
How to Optimize your Mainframe7:52
Optimize your mainframe by preserving COBOL and the technology stack, leveraging IBM upgrade options, consolidating software, and tuning workloads with caching and strategic backups.
Re-hosting Options for the Mainframe9:01
Explore re-hosting options to move mainframe applications to distributed systems, comparing IBM DXi, Micro Focus Clarity, and COBOL hosting tools; assess pros and cons, performance, and retrofit challenges.
File Based to Db2 Migration7:54
This lecture teaches a two-type approach to file-based to Db2 migration, emphasizing field-level usage analysis, selective targeting, and a separate API layer to minimize changes and protect performance.
New Age Differentiators5:07
There are also new age solutions around zCX - Running Containers at scale on Mainframe, Running analytics workload on IBM Mainframe, IBM also announced Dial ISA Process and AI Acceleration, apart from Telum and Spyre processor for both IBM z and LINUXONE - These are huge steps forward in running AI workloads on z. From an SDLC Standpoint - IBM launched BoB - BoB helps in reading Mainframe languages viz. COBOL, CICS, to name a few and create documentation, helps in impact analysis, business rules extraction, COBOL to Java or other languages and many more. The accuracy is so good compared to other LLMs out there. Bob uses Claude Granite and other models underneath and since its IBMs homegrown Mainframe, the accuracy is great with absolutely no hallucinations on complex Mainframe codes. From an IBM Power standpoint , new age options like 1. IBM Power virtual server - Running AS400 or IBM i and AIX workloads on IBM Cloud (Only cloud to offer native services with cores as low as 0.25 and increments of 0.25 and with majority of data centers offering S1122 and E1180 option (As of August 2026). IBM BoB also works on IBM i workloads in terms of Old RPG conversion to RPGILE, Business Rules extraction, code documentation and many more. The field of both IBM Mainframe and IBM z are ever expanding and please reach out for consultancy and architecture discussion on these technologies.
Conclusion5:33
Assess your current landscape, inventory workloads, and identify target options for mainframe modernization. Embrace that modernization is a journey, not a silver bullet, with workload-focused options and realistic timelines.

Requirements

Many Enterprises are challenged with the Beast called Mainframe. The Modern Mainframes provide a lot of options to Optimize and Modernize Enterprise Workloads. This course provides a detailed approach on the various options and best kept secrets to Modernize an Enterprise Mainframe.

Description

Many Enterprises are challenged with the Beast called Mainframe. The Modern Mainframes provide a lot of options to Optimize and Modernize Enterprise Workloads. This course provides a detailed approach on the various options and best kept secrets to Modernize an Enterprise Mainframe.

This course is NOT for beginners, instead its meant for Mainframe Programmers or Architects looking for various options to Modernize their Mainframe. The options vary from short term to long term solutions. Mainframe modernization is a journey which needs to rigorously understood and adopted.

After this course, a thorough understanding and approach towards Modernizing Enterprise workloads in Mainframe will be obtained.

As of August 2026, there has been significant changes in Modern Mainframe and new workloads on IBM Power and z are growing rapidly. Point of view around IBM Bob for z and i, Power Virtual Server are also been added in the description to arouse the interest amongst the students. As always any questions regarding any of the topics which are part of the course or newly added as part of the description can be double clicked.

The landscape is changing rapidly with both platforms - z and power, supporting AI workloads on them. This could be via Telum Processor, Spyre accelerator and recently announced in August 2026 IBM z and IBM LinuxONE Dual ISA Processor and AI Acceleration. This has not been elaborated but this is a topic of architecture and due diligence.
