AnyDB on AWS: SQL Server, Oracle, ASE, MaxDB, Db2

A team is sizing SQL Server for a new SAP NetWeaver landing on AWS and assumes they can use Amazon RDS for SQL Server to offload DB management. Why is that wrong, and what does the SQL Server restriction force onto their EC2 design?

In a MaxDB hot standby setup on AWS spanning two AZs, what is the non-obvious storage requirement that makes the standby's STANDBY/restart mode actually work, and what monitors the primary for takeover?

A customer says they already license 'Db2' and want to run their SAP workload on a Db2-on-IBM-i (or AIX-emulated) partner solution on AWS. Why might that break SAP support, and what is actually supported?

A stakeholder hears 'HANA is built from MaxDB and is its natural successor' and concludes the MaxDB SAP systems need an urgent HANA migration. What's the correct read of the roadmap?

Oracle Data Guard offers three protection modes. Which one will shut the primary down rather than risk data loss, and why is Maximum Availability NOT that mode?

You want one shared file system for an SAP database's data, log, and control files and reach for Amazon EFS. Why is that contraindicated, and is there any SAP workload where EFS is actually OK?

AWS DRS does continuous block-level replication, so a team assumes it guarantees a tight, predictable RPO for their SAP database. Which side of RPO/RTO is actually the weak one, and why?

SAP prefers SQL Server Enterprise Edition everywhere. When may a team legitimately drop to Developer Edition in non-prod, and what licensing fact silently forbids it?

When building SQL Server AlwaysOn AGs for SAP on AWS, how does failover redirection differ from a Pacemaker cluster, and why does that change the IP plan for each node?

An admin instinctively configures RAID 5/10 across EBS volumes for an SAP database 'for redundancy.' Why is that wasted effort on AWS, and what RAID level should they use instead?

What does a basic SAP ASE install consist of, and what is the minimum ASE version supported for NetWeaver on AWS?

When automating Oracle Data Guard failover for SAP on AWS with Fast-Start Failover, where must the observer run, and why is the obvious 'put it on the standby' placement wrong?

Oracle for SAP on AWS requires Oracle Enterprise Linux — and Oracle Linux has no license fee. What recurring cost still applies, and when can you take the cheaper support tier?

SAP ASE HADR ('always-on') replicates between a primary and a companion/standby. For the HA companion vs the DR standby, which replication mode applies to each, and what license gates the whole feature?

SAP MaxDB and SAP liveCache are related but solve different problems. What distinguishes liveCache, and what kind of workload tells you you're looking at liveCache rather than plain MaxDB?

An architect wants Oracle RAC across EC2 instances for scale-out HA on SAP, per SAP Note 2358420. Why does that plan fail, and what Oracle configurations ARE supported on EC2?

A nightly job takes EBS snapshots of an SAP database's volumes with no other steps. Why might a restore come up dirty, and what step makes the snapshot application-consistent?

Db2 HADR offers four sync modes for SAP on AWS. Across a same-AZ HA standby vs a cross-region DR node, which mode sits at each end of the protection spectrum, and what's the trade you're making?

OS-native Pacemaker/WSFC clustering is free, so why would an SAP-on-AWS shop pay for SIOS, NEC ExpressCluster, or Veritas InfoScale instead?

Across the AnyDB engines, what actually distinguishes a pilot-light DR strategy from a hot standby in RPO/RTO terms — and where does cold backup+restore land?

A team wants to lean on EC2 auto-recovery as their database HA mechanism. What does it actually protect against, and which three limits make it inadequate as a real HA/DR plan?

For SQL Server on AWS, a team plans to host data and log files on FSx for Windows File Server for shared access. Why is that not supported, and what is FSx for Windows actually allowed to do here?

For Oracle-for-SAP on EC2, which storage layouts are supported for data/log — and which one will get you an unsupported configuration if you reach for it?

Do you need a different HA/DR playbook for SQL Server, Oracle, Db2, ASE, and MaxDB on AWS, or can one set of patterns cover them all?

How many standby nodes can SAP ASE HADR run, and what changed at ASE 16.0 SP03 PL03 that a Business Suite shop can use but a plain NetWeaver shop cannot?

When replatforming (database change) an AnyDB SAP system onto AWS, which database-specific input complements EarlyWatch Alert reports for right-sizing the target?

For data-at-rest on AWS, which native encryption technology does each AnyDB engine use — and how do Oracle and SQL Server differ from Db2 and ASE?

You're building a modern data pipeline off an SAP system running on Oracle, SQL Server, Db2 LUW/z-OS, or ASE. At which layer do you extract, and which AWS/SAP services fit?

A team migrating several SAP systems to AWS wants to know, before sizing anything, exactly which database engines SAP supports on AWS - and which engine carries an OS restriction the others don't.

During AWS migration planning a stakeholder wants to keep a legacy app-plus-database pairing indefinitely. What SAP maintenance milestone should reshape that plan, and how is it already showing up in the cloud?

You want SAP database backups to land directly in Amazon S3 without a staging EBS volume, but there is no AWS Backint Agent for your engine. What are the AnyDB options?

A shop wants to run SQL Server for SAP on AWS. What are the only allowed licensing routes, and what OS/architecture constraint is non-negotiable?

Unlike HANA, SQL Server and Oracle don't need special database certification to run SAP on AWS. So can you drop them onto any EC2 instance type you like?

Sizing an existing SQL Server or Oracle system for EC2, a team plugs numbers into Quick Sizer and provisions to 100%. What inputs should they actually use, and what buffer does Quick Sizer silently already include?

SAP on AWS is mostly self-managed databases on EC2, yet a few workloads can offload to managed Amazon RDS. Which SAP workloads qualify, what does the managed service handle for you, and what must still run on EC2?

For SQL Server or Oracle data and log on AWS, which EBS volume types are actually SAP-certified, and which one gives sub-millisecond latency for a production Oracle database?

An SAP archiving strategy needs to store sales invoices, purchase orders, and salary slips as electronic documents. Which SAP component handles that on AWS, and what are its two storage-layer options?

You've built AWS-native HA for an SAP database across AZs. What decides whether you still need a separate DR strategy, and if so, what dictates in-region versus multi-region?

For an SAP database's persistent volumes on AWS you're choosing between gp3 and io2 Block Express EBS. What does each optimize for, and when is io2 Block Express worth the extra cost?

You put an SAP database's data and log files on the same FSx for NetApp ONTAP storage virtual machine. Why do the AWS/SAP guidelines tell you to split them across two SVMs, and how granular should the volume layout go?

Oracle-for-SAP backups are accumulating on EBS and inflating storage cost. What's the AWS-native way to cut that, and what hidden catch comes with one of the options?

In an Oracle Data Guard Fast-Start Failover layout the observer sits in a third AZ. What keeps the observer itself alive if its instance dies, and how is it configured on AWS?

Running SAP NetWeaver 7.0x-7.5 on Oracle 18c/19c on AWS pins the database and Oracle-Client app servers to a specific OS. Why can the ASCS/ERS nodes escape that constraint?

A team wants SAP ASE's shared-disk cluster edition to give their SAP system a single-system-view HA cluster on AWS. Why won't that work, and what is ASE's actual HA path?

SAP ASE HADR uses a Fault Manager to trigger takeover, and that classically forced a dedicated third node. How did AWS, SUSE, and SAP eliminate that node, and why is it a win?

A team wants to move an SAP core system onto a cloud-native or managed database on AWS. Why does SAP's certification model block that, and where are modern database models actually allowed?
