What is cloud native?
● Containerized● Dynamically orchestrated● Microservice oriented
● www.cncf.io/about/faq
Apache Spark in the Cloud | Zbyněk Roubalík5
Containers
● A container image is a lightweight, stand-alone,
executable package of a piece of software that
includes everything needed to run it: code, runtime,
system tools, system libraries, settings.
● https://www.docker.com/what-container

VM vs Containers
Apache Spark in the Cloud | Zbyněk Roubalík7
Containers
● Cloud vs standard deployment model
● Pets vs Cattle
● Developers + Operations (Admins) → DevOps
● Docker
Apache Spark in the Cloud | Zbyněk Roubalík8
Kubernetes
● Container cluster manager
Apache Spark in the Cloud | Zbyněk Roubalík9
Kubernetes
● Based on etcd – distributed clustered key value store● Smallest deployable unit is Pod
Apache Spark in the Cloud | Zbyněk Roubalík10
OpenShift
● Open Source Container Application Platform● Focused on application (not just containers as a
concept) and developer experience
Apache Spark in the Cloud | Zbyněk Roubalík11
OpenShift
● Sits on the top of Kubernetes● Source code, builds and deployments management● S2I - Source to Image● Application lifecycle management (CI/CD)● Service catalog (Language runtimes, Middleware,
Databases)● Security

Apache Spark
● Fast and general engine for large-scale data processing
● Distributed computation system
● Provides high-level APIs in Java, Scala, Python and R
● Supports a rich set of tools for Big Data, AI, ML● Spark SQL for SQL and structured data processing● MLlib for machine learning● GraphX for graph processing● Spark Streaming● ...

How to interact with Spark
● Run an application
● Start a REPL● Scala
● Python
● R
