Serverless is an abstraction of infrastructure and
its operations including provisioning, scaling,
patching, etc.
FaaS (Functions-as-a-Service) is the compute
component in a serverless platform

Was ist Autonomous (autonom)?
11
10 Millionen

Autos bis 2020
- Forbes (2017)
KI hat größeres
Potential als die
Dampfmaschine
– McKinsey (2019)
RPA (Robotic

Mainstream
- Gartner (2019)

12.
Serverless ist die Abstraktion der Infrastruktur und des Betriebs, das
Provisionierung, Skalierung, Wartung u.a. inkludiert
Der Betrieb der Infrastruktur ist automatisiert & wird vom Provider bereitgestellt.
Autonomous Services = autonome Dienste kennzeichnen sich durch den hohen
Automatisierungsgrad aus, der Nutzer braucht sich nicht um Betrieb & Wartung
des Services kümmern, z.B.: AWS Lambda, Azure und Oracle Functions, Oracle
Autonomous Database Services

Functions with Persistence Autonomous Database Benefits
• Fully managed, self tuned database
• Complete infrastructure automation
• Consolidation and standardization:
multi modal polyglot
• Security: automated patching/updating
• Interoperable with any development, data
integration, analysis and reporting tool
• Multitenant, pluggable architecture
Block, File Storage Benefits
• Durable Oracle Cloud Infrastructure
storage, external to Functions
• Enable scalable and resilient architecture
• Dynamic provisioning
Persistence allows containers to “remember” - Mechanisms for persistence: API call

Fn Project im Überblick
✅ Open Source—no vendor lock-in
✅ Platform Independent—laptop, server, cloud
✅ Approachable—easy for new users, low level controls for advanced users
✅ Docker Based—leverage Docker ecosystem
✅ Scheduler Independent—deploy to Kubernetes, Swarm, Mesos, etc.

21.
Functions == Containers
▪ Functions are packaged as containers—
so any container can be deployed as a
function
▪ Package and reuse open source libraries
as functions!
21

22.
Was ist eine Fn Function?
• Small chunk of code wrapped into a container image with all dependencies
• Fn server passes in function input and environment
• Fn server returns results to caller
• STDERR automatically routed to logs
The Fn server handles everything else, like the API gateway, piping things around, storing logs,
etc.
22

23.
Fn CLI
fn init --runtime go
fn deploy --app myapp
fn invoke myapp myfunc
→
http://localhost:8080/t/myapp/myfunc
23

24.
Fn Function deployen
1.Builds container (multi-stage) + bumps version
2.Pushes container to registry
3.Creates/updates function & triggers (fn servers lazy load images)

Fn Function Debugging
fn update app cloudevents --syslog-url="tcp+tls://logs7.papertrailapp.com:40277"
Metrics created using OpenTracing w/ initial collectors and extensions for Prometheus, ZipKin,
and soon Jaeger
25

26.
Function Development Kits (FDKs)
Familiar syntax for Lambda developers
Simply write a `handler` function that adheres to the FDK’s interface and the FDK will provide
the input to your function, as well as deal with returning the proper output format.
FDKs make it easy to write functions

Autonomous Database Dedicated
• Administrator specifies size, region, and
availability domain of dedicated Exadata Systems
• Billed hourly after the first month
• Administrator then partitions the system by
specifying container databases
• Database users provision databases within the
container databases
• Users just specify DB compute (OCPUs) and storage
capacity
• CPU and storage can grow or shrink online
• Bring your database licenses or pay-per-use for
software

Autonomous DB Dedicated Isolation
52
RAC CLUSTER
• Dedicated allows multiple levels of isolation
– Database (DB)
– Container database (CDB)
– Cluster of VMs
– Separate Hardware (Exadata Infrastructure)
– Hardware Enforced Private Network (VCN)
• The level of security and performance isolation can
be tailored to the needs of each database
• Implementing isolation is normally complex but in
autonomous you just specify what you want

• Customize database separation policy
• Separate critical, general purpose, and test databases
• Separate databases by organization (sales, HR, marketing)
• Customize software patching and upgrade policies
• Deploy new versions on test/dev database before production
