Vision: Intelligent Enterprise is an integrated enterprise.
• Integrate anything (people,
things, processes and data) ,
anywhere (on-premise/cloud,
edge)
• Share real-time data with
supply chain, business network
and customers with APIs
• Orchestrate people, processes,
events, and things with digital
workflows and automate decision
making with dynamic business
rules.
• Enable omni-channel
experiences with APIs
• Integrate SAP and non-SAP apps
in cloud and hybrid landscapes
• Real-time and connected end-
to-end processes (Hire to
Retire, Lead/Consume to Cash,
Procure to Pay)
• Sense and respond to
business events proactively
Real-time
digital interactions

What are serverless architectures?
Server less
Serverless does not mean there aren’t any servers.
There are still servers in serverless architectures,
but the servers are implemented and scaled by the
cloud provider.
The “less” in serverless means less of the following
for you:
✓ Less costs thanks to pay-per-use
✓ Less complexity through auto-scaling
✓ Less time spent on operations
✓ Less dependencies on infrastructure

15. 15PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Serverless means more…
✓ More time to focus on developing application code
✓ More money to spend on resources you really use
✓ More work for the cloud provider, less work for you!
Serverless architectures shift the
workload from users to cloud
providers.
Server less = more

SAP Cloud Platform Enterprise Messaging is a messaging service that connects apps and services.
It includes events enablement so your applications can publish and consume events as part of an event-driven
architecture.
SAP Cloud Platform Enterprise Functions (beta) to build, run, and manage ephemeral application functions.
Use functions to build new applications and extensions that can react to triggers across clouds and landscapes.
SAP Cloud Platform Backend service (beta) to build, run, and manage enterprise-ready APIs powered by a
fully-working backend generated on the fly.
SAP Cloud Platform API Management to expose data and processes as APIs and manage their lifecycles.
Use services individually or in combination to implement an event-driven, serverless architecture for the
intelligent enterprise.
This is the current state of planning and may be changed by SAP at any time.

19. SAP Cloud Platform
Enterprise Functions

20. 20PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Is a fully managed compute service, which provides a
platform on which to execute ephemeral, stateless
functions in a serverless environment.
Function as a Service
What are functions?
Functions are atomic, stateless, pieces of code executed on demand
in response to triggers from other applications and services.

21. 21PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Functions in serverless, event-driven architectures
Functions are atomic pieces of custom code executed in response to triggers, for
example, events, in a serverless environment.
▪ Functions are invoked by triggers (e.g. events, timer, HTTP call), which define
how the function code implementation shall be invoked and the output returned.
Function-as-a-service characteristics:
▪ Enable auto-scaling in serverless environment
▪ Can be triggered by events (event-driven)
▪ Facilitate usage-based billing (pay-per-use)
▪ Ensure efficient resource utilization

Event-driven/Hybrid
enablement
▪ Build new apps and extensions
with functions that can be
triggered across clouds and
systems.
SAP Cloud Platform Functions advantages
Serverless
▪ Cloud providers (vendors, not
users of the service) take care of
all computing resources.
▪ Stateless compute containers are
event-triggered and fully
managed.
▪ Users can concentrate on code
development, not operational
overhead, meaning labor cost
gains.
On demand
▪ Application functions are
ephemeral and triggered on
demand, for example, by an
event.
▪ Facilitates development of
microservices.
Pay-per-use
▪ Pay only for what you actually
use when function is executed.
▪ Enables microbilling for time and
resources used during execution
of function.
▪ Caters for payment of
inconsistent traffic.

24. 24PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Summary
SAP Cloud Platform Functions, SAP‘s Function as a Service for serverless environments, provides the
following advantages:
“Just Run My Code”
Fast Time to Value Dynamic Scalability Reduced
Operations
Low TCO

Enterprise Messaging

26. 27PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Communicate reliably
▪ Messaging middleware
decouples communication
between senders and receivers
for greater scalability.
▪ Choose from different Quality of
Service levels for MQTT to
ensure messages are delivered
reliably.
SAP Enterprise Messaging – key capabilities
This is the current state of planning and may be changed by SAP at any time.
Decoupling communication between services and applications in hybrid landscapes with
reliable and secure messaging capabilities and event enablement.
Connect seamlessly
• Connect your applications and
services seamlessly using
standard protocols (MQTT, AMQP
1.0, REST)
• Java JMS and Node.js support
• Exchange patterns (e.g. pub/sub,
point-to-point, request/reply)
High throughput
▪ Asynchronous message patterns
provide elasticity meaning it’s
easy to handle unexpected peaks
in data traffic.
Handle enterprise events
▪ Messaging transports events
from the backend to the Cloud for
seamless integration of hybrid
landscapes.
▪ Build applications and extensions
that can react to events from
SAP S/4HANA out-of-the-box.

27. SAP Cloud Platform
Backend Service

28. 30PUBLIC© 2018 SAP SE or an SAP affiliate company. All rights reserved. ǀ
Web and mobile apps require a similar set of features on the backend
(e.g. storage, notifications)
Backend as a Service ensures developers no longer need to
develop a separate backend for each of the services their apps need to
access.

SAP Cloud Platform Backend service (beta)
Key Features
Generate APIs implementing open protocols (OData V2 and V4) based
on CDS/OData V2 EDMX /Open API data model.
Complete abstraction of the underlying infrastructure that is running the
application logic (in serverless environment).
Automatic scaling of the necessary resources to host the APIs (in
serverless environment).
Micro billing for only the time/resources/storage expended for creating
APIs and during the execution of these APIs.
Events subscribed can be raised automatically out of the API operations.
Enterprise ready APIs are powered by SAP HANA.
