Container-based Service Deployment in Private and Public Clouds Enrico Bocchi CERN IT-ST CS3 2018 Workshop on Cloud Services for Synchronisation and Sharing 29th January 2018 Krakow, Poland

Container Technologies Containers Light-weight application-layer virtualization Isolation: From other Apps and OS Portability: Binary, Data, Config, Logs Container Orchestration Deploy and manage complex services Scalability and high-availability Can we containerize and distribute CERN storage services and deploy them on any cloud? Introduction Architecture Scalability Use Cases Conclusions CS3 2018, Krakow 2

Containerized CERN Technology Boxed – Self-contained, Docker-based package with: EOS: Disk Storage for LHC physics data, and CERNBox EOS the CERN disk/cloud storage for science, Luca Mascetti [email protected]:50 CERNBox: Cloud Sync&Share for Science CERNBox Service, Hugo Gonzalez Labrador CERN IT-ST [email protected]:45 CERN IT-ST SWAN: Platform for Interactive Data Analysis in the Cloud SWAN: Service for Web-based Analysis, Diogo Castro [email protected]:00 CERN IT-ST EP-SFT Introduction Architecture Scalability Use Cases Conclusions CS3 2018, Krakow 3

Containerized CERN Technology Boxed – Self-contained, Docker-based package with: One-Click Demo Deployment Production-oriented Deployment Single-box installation via dockercompose Container orchestration with Kubernetes Scale-out storage and computing No configuration required Tolerant to node failure for high-availability Download and run services in 15 minutes https://github.com/cernbox/kuboxed https://github.com/cernbox/uboxed Introduction Architecture Scalability Use Cases Conclusions CS3 2018, Krakow 4
