The document discusses using MongoDB to modernize mainframe systems by reducing costs and increasing flexibility. It describes 5 phases of mainframe modernization with MongoDB, from initially offloading reads to using MongoDB as the primary system of record. Case studies are presented where MongoDB helped customers increase developer productivity by 5-10x, lower mainframe costs by 80%, and transform IT strategies by simplifying technology stacks.

6. Challenges of Mainframes in a Modern World
There are three areas of Data Management. In the legacy world these have been disconnected with
many technologies attempting to achieve an integrated the landscape.

7. 5 phases of Mainframe Modernization
MongoDB will help you simultaneously offload critical services from the mainframe, save millions in
cost and increase agility for new use cases.
Scope
BusinessBenefits
Transactions are written first to MongoDB, which passes
the data on to the mainframe system of record.
Writes are performed concurrently to the mainframe as well
as MongoDB (Y-Loading), e.g. via a service-driven
architecture.
The Operational Data Layer (ODL) data is enriched with
additional sources to serve as operational intelligence
platform for insights and analytics.
Enriched ODL
Records are copied via CDC/Delta Load mechanism from
the mainframe into MongoDB, which serves as Operational
Data Layer (ODL), e.g. for frequent reads.

applications, with deferred writes to the mainframe if
necessary.

8. Offloading Reads
Initial use cases primarily focus on offloading costly reads, e.g. for querying large numbers of
transactions for analytics or historical views across customer data.

9. Offloading Reads & Writes
By introducing a smarter architecture to orchestrate writes concurrently, e.g. via a Microservices
architecture, you can shift away from delayed CDC or delta load mechanisms.

Writing (some) data concurrently into the mainframe

interactions with the mainframe technology .
It also sets you up for a more transformational shift of

enterprise architecture.

10. Transforming the role of the mainframe
With a shift towards writing to MongoDB first before writing to the mainframe (if at all) you are further
changing the meaning of “system of record” and “mainframe” within the organisation.

20. Developing a sophisticated data management strategy requires many components. The required range
of expertise is very broad, and many organisations struggle delivering using only in-house resources.
Implementation Considerations
Key Architecture Components:
• Access Management
• Virtualization or Containers
• Security & Entitlements
• Accounting and chargeback
• Backup and Recovery
• Distributed computing
• Server Hardware
• Storage
• Operating System
• Infrastructure Management
• etc.

21. Reduce bloated infrastructure
MongoDB enables you to eliminate technical debt for data storage, enabling more modern deployment patterns using
hybrid cloud strategies and more efficient utilization.
Under-utilization & Special Hardware
Legacy systems often reside on dedicated physical
hardware. Under-utilization and high maintenance
costs make up a large part of overall storage costs.

By removing layers we can:
• Reduce complexity
• Reduce cost
• Increase business agility
• Improve data quality
• Improve service quality
• Enable innovation

24. Technical Debt Limits Innovation
Legacy IT landscapes which have grown over time usually display 3 main drivers of impedance mismatches that limit an
organization’s capability to innovate and deliver modern IT services:
Data
Duplication
Bloated
Infrastructur
e
Complicated
Software Stacks
• Costly data reconciliation &
management workflows
• Low data quality and lack of
ownership / responsibility
• Reliance on “scale up” model
• Large footprint of costly
storage area networks
• Outdated, dedicated
infrastructure strategy
• Too many layers, driving
complexity & time to market
• Hiding deficiencies, e.g. by adding
caching for high-frequency access
• Clash between object-oriented
development vs. relational data
MongoDB can help you address all 3 drivers and help you unleash potential to innovate

25. Legacy
Legacy RDBMS systems are falling short
RDBMS systems were not created for today’s requirements and consequently try to bolt-on features to
compensate for the lack of capabilities. But this strategy can’t compete with data management systems
designed & purpose-built to solve today’s problems.
Rigid Schemas
Resistant to
change

26. Scope
BusinessBenefitsAdoption Roadmap
Adopting MongoDB for individual projects and applications will unlock many benefits over using
legacy technology. Those gains can be further increased through a more strategic adoption.
Data as a Service
(DaaS & BaaS)
Data as a Service is an advanced way of storing and
accessing data enterprise-wide and yields a multitude of
benefits, e.g. improved data quality, reduced costs, and
improved governance.
Database as a
Service (DBaaS)
Automating provisioning of databases in your
organisation will considerably decrease the burden on
your operations teams and increase development
productivity and business agility.
Adopting MongoDB as strategic solution will help you
drive innovation and deliver on business
transformation agendas through increased efficiency &
capabilities.
Multiple projects/
strategic adoption
MongoDB as operational database for a single project is
usually the first step for our customers. Many leverage
our professional services to help design & deploy
according to best practices.
Single projects
& applications
Leap-frogging steps due to
faster skill adoption or new
business requirements is not
uncommon
