This document discusses using Skytap on Azure to provide high availability and disaster recovery for IBM Power Systems workloads in the cloud. Some key points: - Skytap on Azure allows customers to run their IBM Power and x86 applications natively in Microsoft Azure without refactoring. This enables easy migration and modernization. - It provides a familiar environment for IBM Power applications in Azure, requiring no training, changes, or refactoring. Workloads run securely with low-latency connectivity between on-premises and Azure networks using ExpressRoute. - Skytap on Azure is available in several public Azure regions globally. Customers can use it for production workloads with high availability, as well as disaster

- 5. 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
- 6. 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
- 7. 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
- 8. 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
- 9. Operating in the Cloud Same IBM i, different environment
- 10. 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 SYS 1 LPAR A SYS 2 LPAR B Primary Backup LPAR C
- 11. 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 West LPAR C East LPAR A
- 12. 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 HardwareSN=AAA111 V1-1111 HardwareSN=CCC111 HardwareSN=BBB222 HardwareSN=DDD222 V0-1111 V0-2222 Site 2 Site 1 Primary Backup Logical Replication V1-2222

- 14. 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!

Complete Infrastructure Flexibility Technology highlights • Hardware-independent replication technology enables infrastructure choice and flexibility • Mix of IBM i server models • Mix of supported IBM i OS versions • Mix of storage types • Mix of physical, virtual and cloud servers • Mix of network types • Supports Managed Services and Cloud • Ground to Cloud • Cloud to Cloud • Cloud to Ground How it adds value • Assure MIMIX HA gives you the flexibility to replicate between the IBM i environments that work best for you and your budget Virtual LPARs Physical Cloud
