The question is no longer:

“Should I migrate

my SAP systems

to the cloud?”

5

• GCP – all inside their network

• Secure and fast communications

• AWS – secure systems all built and run by AWS

• Most clients ?

• First to market advantage

• Azure – Knowledge, hardware

• CHOICES CHOICES

But - Which cloud for SAP?

6

Which cloud for SAP?

• SAP solutions are cloud infrastructure agnostic

• SAP specific know-how is the main differentiator

• Long term partnership

• Microsoft USE SAP

• Project Embrace

• Reference architecture

Why Hasso Plattner Invented HANA

11

massive Memory demands – most SAP customers need a HANA system up to 3 TB, some up to 25 TB

Storage – write performance is key for transaction response time

Storage – read performance is key for trend analysis on historical data

Growth of memory depends on complexity of reports (amongst other factors)

Public clouds are fully certified to cope up with HANA

The Challenge Of HANA

12

In the past sizing was

focussed on SAPS, the

“horsepower” of SAP

With HANA sizing is focussed

on database memory only

Rule of thumb:

• 60% of HANA memory

for data

• 40% for HANA operation

App servers

• 4 vCPU, 16GB for ABAP

• 8 vCores; 32GB for JAVA

SAPS Numbers Became Useless –

Memory Is The New King!

13

And Storage Throughout The New Frontier

If HANA can’t write fast enough -response time will suffer.

If HANA isn’t fast enough -system start will be prolonged.

• Data volume: 1, 2x net data size on disk

• Log volume: ½x RAM up to 512 GB,512 GB for larger systems

• Shared volume: 1x RAM up to 1 TB,1 TB for larger systems

• Operating System needs a 100 GB LUNfor binaries and configuration files.

14

In-Memory Databases and the Alzheimer effect:

What happens to my data if the data center catch fire?

15

HA And DR For HANA

Clouds grant 99.90% per VM

Premium disk are mirrored 3X

VMs booted on a healthy host within ~8 minutes in case of a hardware failure

but ……

• Very low RTO (< 1 hour)

• Enables parallel read

• Enables secondary time travel

(shadow database)

• Mitigate logical disasters (User deleting

tables by mistake etc.)

Transition – just move to the cloud

No changes of business processes or custom code

Only technical tests necessary

Just a weekend downtime for production systems

OS/DB Migration – also change of OS and/or DB

No changes of business processes or custom code

Only technical tests necessary

Just a weekend downtime for production systems

S/4 Conversion – also change from ECC to S/4

Adaption of business processes and custom code

Functional tests with LoB necessary

DMO Migration To HANA

• At least ECC EHP6 SP16 for a

HANA migration

• SAP Database Migration Option

(DMO)

of SAP Software Update Manager

(SUM) enables a combination of

update and

"in-place" HANA migration

• SID/logical system remain the same

preserving the connectivity in the

system.

• DB source remains consistent for

fallback

• 1 Weekend of downtime only

Reduced number of data tables from 25,000 in ECC to 7,000 in S/4HANA

If Z-ABAP cant read a defunct table, the table is emulated. Writing no longer possible!

All Custom Code (Z-ABAPs) must bechecked with the SAP Custom Code Check Tool as part of an S/4 conversion

Code that "fails" in this check must beadapted to the new data structure of S/4

Average ECC has 5,000 to 15,000 Custom Objects
