Public clouds
and SaaS

What’s driving the
move to the Cloud
• Lower costs
• Better collaboration
• More flexibility and agility
• Increased security
• Work from anywhere
• Minimal IT infrastructure
• Always up-to-date
• Backup and disaster recovery
• Document access and control
• Predictable, budgetary pricing

IBM i Migrations – Getting to the Cloud
Many reasons for migrating
• Leveraging the many Cloud and Managed
Hosting options now available for IBM i
• Upgrading you Power Systems Hardware
• Growing business demands and transaction
volumes hitting CPW constraints
• Aging Power7 and Power8 hardware limiting
overall modernization options
Getting there can be a challenge
• Justifying investment in this extremely uncertain
business environment
• Scale and complexity of integration requirements:
IBM i impacts everything else!
• Managing the burden of migration workloads
and risks

Typical migration
challenges can
incur penalties for
missed deadlines
and SLAs
Downtime
Tape not
an option
Operations cannot tolerate the
downtime required by traditional
migration methods
Tape is too slow and unreliable for
migration. Read errors can abort
the migration.
Limited or no tape availability in
Cloud environments
Problems after
cutover
Fallback
planning
Lack of infrastructure and
application testing before cutover
leads to late discovery of issues
Lack of viable and robust fallback
planning lead to extended
downtime and unresolved issues

Precisely
survey of IBM i
professionals
confirms the
risks are real
60% 46%
Delayed migrations because
of concerns about business
disruptions and downtime
Spent over 50 hours to plan
and execute their last migration.
Over one-quarter said their
migration took over 100 hours
to plan and execute
44% 31%
Said migration caused 6+ hours
of downtime, while 26% said
longer than 13 hours
Experienced a serious migration
failure. The most common failure
was being unable to restart
critical applications within the
required timeframe

Operating in the Cloud
Same IBM i, different environment

Cloud Environment Basics
Cloud Environments are Virtual Environments
• IBM i is running 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 may be in use
• Limited access to physical tape devices
• Limited access to hardware
• IBM i performance fundamentals still matter!
• Cloud LPARS must have underlying processor, memory
and storage resources to support the application
processing requirements

LPAR A
SYS 2
LPAR B
Primary Backup
LPAR C

Cloud Environment Basics
Software Licensing needs to accommodate
cloud operating environments
• LPARs are Mobile
• Live Partition Mobility Events may occur
• Physical Serial numbers will change
• Hardware features will change
• Capacity is the new licensing metric Primary Backup

LPAR A

Logical Replication and
Virtual Server Serial Number Support
• A Virtual Server Serial Number (VSSN) enables a
globally unique serial number for a virtual LPAR.
• This LPAR can move across multiple physical serial
numbers.
• VSSN allows software licensing to be tied to a serial
number that is mobile, such as in a cloud or multi-
tenant computing environment
• Replicate to/from Virtual Servers with Virtual Serial
Number for HA and DR!
• Virtual Server with Virtual Serial number

Sync-by-Wire
Tape devices scarce in the cloud
• LPARs are scratch loaded with an OS/TR/Cum level
• OS Maintenance is done by the user
• Full system restores may or may not be possible
• Shipping tape for restore operations is impractical
• Start up the scratch installed LPAR and bring everything
over though the network!
