Why mainframe data cyber resilience matters now
While the mainframe remains the most reliable platform in the enterprise, handling 68% of global transactions with 99.9999% reliability1., the risk landscape around the mainframe has changed.
- Ransomware increasingly targets backups and secondary storage, not just production systems.
- Regulators are demanding proof – not just a plan – of operational resilience.
- More than ever, organizations need a modern, efficient path to object storage in the cloud to make your data available and actionable for AI/ML analytics.
Organizations successfully navigating this moment aren't ripping out their mainframes — instead, they are bringing their siloed mainframe data into their enterprise data strategies. BMC AMI Cloud and AWS provide a safe, incremental way to do just that,

Achieve mainframe data cyber resiliency with BMC AMI Cloud + AWS
A safe, incremental evolution — not a rip-and-replace
BMC AMI Cloud works alongside your existing tape and VTL infrastructure, letting you selectively re-tier secondary mainframe data to Amazon S3 on your own timeline. No forced cutover. No application changes. No outages.
-
The mainframe stays the system of record, processing trillions of transactions with 99.9999% reliability
-
AWS and BMC become your resilience and innovation layer
-
You plan, test, and validate the transition on your own terms
BMC AMI Cloud Architecture with AWS
1. Capture Mainframe Data
The BMC AMI Cloud Agent reads any z/OS® dataset, backup image, archive file, or full database dump from mainframe applications, VSAM, files, tape, and image copies for cloud protection.
2. Enable Cloud-Native Access
Identify and access the required data for cloud processing and analytics. Alternatively, applications can write directly to an AMI Cloud virtual Cloud Data Set, providing transparent cloud integration.
3. Optimize and Secure Data
Use the BMC AMI Cloud Agent to securely transfer mainframe data to AWS over TCP/IP. The agent receives the data stream, segments it into optimized chunks, compresses it, encrypts it, and prepares objects for cloud storage.
4. Transform and Process Data
The agent performs parallel writes of encrypted data chunks as objects to Amazon S3, maximizing throughput and reducing backup windows. Run BMC AMI Cloud Data and Analytics on AWS EC2 to transform and prepare the mainframe data.
5. Manage Lifecycle and Capacity
The processed data is stored in Amazon S3 object storage for cloud-based access and analytics. The BMC AMI Cloud Management Server automatically manages retention policies, expiration, cataloging, and object storage capacity utilization.
6a. Prepare Data for Analytics
Use BMC AMI Cloud Analytics to organize and make the data available for downstream analytics.
6b. Restore Data on Demand When recovery is requir
When recovery is required, the Agent reads data directly from Amazon S3 object storage and restores it to mainframe DASD with full data integrity.
7. Query and Integrate Data
Use AWS Glue and Amazon Athena to catalog, integrate, and query the data stored in Amazon S3.
8. Analyze, Visualize, and Monitor
Use Amazon Redshift and Amazon QuickSight for analytics and visualization, with Amazon CloudWatch providing monitoring.
Data Recovery, Built for the Mainframe
Resilience isn't defined by uptime alone — it's defined by whether you can prove recovery when it counts. BMC AMI Cloud creates immutable backups in Amazon S3 that ransomware cannot alter or delete.
Paired with a validated recovery path, this joint solution can detect and isolate the intrusion, identify the gold backup, remove malware, then restore and recover transactions.

Built for Regulatory Reality
The EU's Digital Operational Resilience Act (DORA), in force since January 2025, requires financial institutions and other critical infrastructure operators — mainframes included — to prove resilience against disaster and cyberattack through independent testing. The UK's PRA Supervisory Statement SS1/21 sets similar expectations. Non-compliance with DORA alone can cost up to 2% of global annual turnover.
BMC AMI Cloud + AWS build geographic redundancy and out-of-region recovery into your mainframe architecture, keeping your mainframe data under your control as it moves to Amazon S3 object storage in the cloud — helping you meet data residency and sovereignty requirements without re-architecting how data is stored and governed. AWS has been named a “Critical Third Party” for compliance and regulatory use cases in the UK and EMEA.
Ask yourself: “How am I responding to regulatory pressures like DORA, ISO 20022, and NIST — and can my recovery strategy meet board-level requirements?”
How to make mainframe data available for AI and analytics
Turn protected data into a strategic asset
Once mainframe data is stored in Amazon S3, BMC AMI Cloud converts it into open formats, making it available to enterprise applications, AI and machine learning, and analytics use cases. The conversion does not consume mainframe MIPS and does not require application changes.
