dA Platform is a production-ready platform for stream processing with Apache Flink®. The Platform includes open source Apache Flink, a stateful stream processing and event-driven application framework, and dA Application Manager, a central deployment and management component. dA Platform schedules clusters on Kubernetes, deploys stateful Flink applications, and controls these applications and their state.

THE NEED FOR STREAMING PLATFORMS
DevOps model
Integration with
internal infrastructure
Integrate once,
scale adoption
within organization
Focus on use-cases
instead of infrastructure
• Logging
• Metrics
• State storage
• Data access
• Security
• Auditing

STATEFUL STREAMING OPERATIONS
Managing a stateful stream processor
on stateless containers is challenging.
STATEFUL STREAM
PROCESSING
Stateful stream processing
is disrupting analytics and
application development.
KUBERNETES AND THE
WORLD OF CONTAINERS
Kubernetes offers easy to use
container orchestration. But
containers are stateless.

HOW DOES IT WORK?

DECLARATIVE CONTROL OF DEPLOYMENTS

takes care of configuring, deploying and operating it.

DECLARATIVE CONTROL IN ACTION
Deployment spec
state: cancelled
job: fraud-detection.jar

In this case, the specification of a deployment
changed to “cancelled”.
The Flink cluster in Kubernetes will be deallocated.

reflected in the cluster.

MANAGING STREAMING APPS AND STATE
dA Platform allows to perform stateful
deployment changes.
Deployment changes:
• Upgrading the Flink job
• Upgrading Flink
• Changing the parallelism
• Changing resource allocations
• Changing a configuration parameter
• Suspending / resuming a deployment
• …

ARCHITECTURE
All components of dA Platform are shipped as Docker containers
We provide an installer for setting up the platform
on Kubernetes
The containers for Flink follow the same versioning scheme as the
Apache Flink releases. The dAP distribution Flink has minor patches:
compatible with the open source releases.
Metrics and logging components are provided for demonstration
purposes. We recommend integration with existing systems.

ROADMAP
Improved Access Control
Introduce ownership for resources
(deployments, savepoints, jobs), control
access based on ownership.
Metadata management
Awareness for data sources such as Kafka
topics, files in S3 or HDFS.
SQL
SQL will be a first class citizen of dA Platform
with interfaces for interactive queries and
integration with existing SQL tools.
Multi-Datacenter fail-over
Run dA Platform in redundant data centers,
automatically moving the processing to a
standby data center in case of a failure.
