Are you considering leveraging the cloud alongside your existing IBM AIX and IBM I systems infrastructure? There are likely benefits to be realized in scalability, flexibility and even cost. However, to realize these benefits, you need to be aware of the challenges and opportunities that come with integrating your IBM Power Systems in the cloud. These challenges range from data synchronization to testing to planning for fallback in the event of problems. Join us for this webcast to hear about: • Seamless migration strategies • Best practices for operating in the cloud • Benefits of cloud-based HA/DR for IBM AIX and IBM i

IT support.

5. 2024 trends in HA/DR in the cloud
• Cloud providers will invest
heavily in automating
disaster recovery
workflows.
• This includes automated
failover, failback, and
testing procedures,
minimizing human
intervention and ensuring
faster recovery times.
Focus on Automation and
Orchestration
• Organizations with
complex IT environments
will adopt multi-cloud or
hybrid cloud DR strategies.
• Replicating data and
applications across multiple
cloud providers or a
combination of on-
premises and cloud
infrastructure for added
redundancy and flexibility.
Multi-Cloud and Hybrid
Cloud DR Strategies
• Cloud providers will
prioritize robust security
features within their DR
offerings.
• Encryption of data at rest
and in transit, multi-factor
authentication, and
vulnerability management
tools to ensure data
security during disaster
recovery scenarios
Enhanced Security Measures
5
• We may see the use of
AI/ML for predictive
analytics within DR
• Enables proactive
identification of potential
issues, automated resource
scaling during peak
demand, and faster
recovery times through
intelligent decision-making
Rise of AI and Machine
Learning

6. • As data privacy regulations
continue to evolve, cloud
DR solutions will need to
adapt to meet stricter
compliance standards.
• Includes data residency
options and comprehensive
audit trails for recovery
processes.
Evolving Regulatory
Compliance Requirements
• Cloud providers will offer
more granular control and
flexible pricing options for
DR services.
• Businesses will pay only for
the resources they use and
optimize costs based on
their specific disaster
recovery needs
Growing Emphasis on Cost
Optimization
• Growing focus on disaster
prevention strategies.
• Includes proactive
infrastructure monitoring,
vulnerability management,
and comprehensive
security practices to
minimize the likelihood of a
disaster occurring in the
first place.
Focus on Disaster Prevention

2024 trends in HA/DR in the cloud
• Leverage the scalability,
cost-effectiveness, and
ease of deployment offered
by DRaaS solutions.
• Pre-configured disaster
recovery infrastructure in
the cloud, eliminating the
need for extensive upfront
investment and in-house
expertise
Increased Use of of Disaster
Recovery as a Service

7. Downtime is expensive
• Ironically, avoiding planned downtime for
necessary bug fixes and security updates results in
a greater risk of unplanned downtime
• On average, unplanned downtime costs 35%
more per minute than planned downtime**
• The cost per minute for small businesses lands
around $427 … for larger businesses, it'll be closer
to $9,000*
• The average revenue cost of an unplanned
application outage can exceed $500,000 per
hour for large enterprises in any sector

8. Cloud HA 101

9. Cloud Basics for Power Systems
Cloud Environments are Virtual Environments
• IBM i and AIX runs on virtual LPARs (a.k.a. VMs) configured
via cloud software consoles provided by the Cloud provider
• It is all about the LPAR, not the hardware!
• The LPAR will run on different hardware within the cloud
• Serial number may change, or Virtual Server Serial
Numbers (IBM i) may be in use
• Limited access to physical tape devices
• Limited access to hardware
• Performance fundamentals still matter!
• Cloud LPARS must have underlying processor, memory
and storage resources to support the application
processing requirements

10. Cloud Environment Basics
Software Licensing needs to accommodate
cloud operating environments
• LPARs are Mobile within the cloud
• Physical Serial numbers will change
• Hardware features will change
• Capacity is the new licensing metric

11. Sync-by-Wire
Physical Tape devices scarce in the cloud
• LPARs may be scratch loaded with an OS/TR/Cum level
• OS Maintenance is done by the user
• Full system restores take longer
• Shipping tape for restore operations may be impractical
• Start up the scratch installed LPAR and bring everything
over though the network!

12. HA/DR for IBM Power Systems

13. Migrate While Active to the Cloud!
Logical Replication enables a synchronized
Pre-Production migration target
• Migration Target LPAR in sync real-time with old production system

logical volume level
• Data Tap duplicates every data modification (add/change/delete)
operation at the logical volume level from business applications within
a ‘protected volume group’ to a ‘journal’
• The journal is a logical volume that is part of the same protected volume
group, a separate volume group or a separate disk
• LFCs contain before & after images of changed data blocks plus time
stamp and other metadata

27. Snapshots and Virtual Role Swap
27
Snapshot
• A “view” of the recovery server data at a specific point in time
• Can be rewound to a point in time, down to a second
Snapshots allow you to
• Perform virtual role swaps with no production server downtime or
impact to your RPO/RTO SLAs
• Test Migrations to the cloud before going into production
• Perform consistent hot tape backups
• Validate data before saving to permanent storage
• Perform point-in-time data mining (CDP)
• Generate point-in-time reports (CDP)
• Recover specific point-in-time data items (CDP)
• Create archives
Disk space-efficient snapshots have their own snapshot journal
and work independently of the replica

29. Wizards Simplify Snapshot & Rollback
29
Snapshot Recovery Wizard
• Quick creation of a snapshot to any point in time – to any
second in the rollback window
• Mounts file systems so they are ready for application use
• Can also specify a file system consistency check
Production Server Rollback Wizard
• Undo changes on the Production Server Mounts file
systems so they are ready for application use
• Useful when the production database becomes corrupt
because of logical corruption check

30. Guided wizards make disaster recovery simple and reliable
• Allows easy failover from production to the recovery server
• Recovery to any point in time
• If a DB corruption propagates to the recovery server, recover to an
earlier point in time when data had business-level consistency
• If failure occurs during routine processing (e.g. end of month), restore to
before the failure and re-run the process.
• Align RPO with business process lifecycles
• Planned or Unplanned failover options
• “Digitized” DR Runbook: Prompts the administrator at logical
verification points during the failover procedure
• Use snapshots to verify desired recovery point
• WAN-optimized Resync process ensures minimal amount of
replication
• Planned Failback procedure
