OpenNebulaConf2017EU: Providing cloud and Managed Hosting Environment by Michael Kutzner, Virtion
0 likes438 views
Virtion provides managed hosting and IT services using an infrastructure as a service platform based on OpenNebula. The platform utilizes multiple server clusters across two datacenter locations plus external clouds for scaling. OpenNebula has been in use since 2011 to manage all IaaS resources, both for Virtion's hosting customers and for managing customer on-premise locations. Block storage is provided by Storpool which has been in production since 2016 and provides high performance storage across two clusters located in separate fire zones. Future plans include upgrading OpenNebula, taking new Storpool features into production like cross-zone replication, expanding container services, and automating monitoring.

- 1. Managed Hosting Environment based on OpenNebula
- 2. virtion – Hosting and IT Services Hosting and Cloud-Services in german datacenters Infrastructure as a Service Virtual Data Centers Application Management Fully ISO-27001certified since 2011
- 3. Hosting Environment Highly available infrastructure Different server clusters • Each availability zone • 2 datacenter locations plus external clouds (for scaling out) • Infrastructure • computing • Storage • Managed Services • Tailored solutions
- 4. Full operations and management support Monitoring Performance monitoring Service Level Awareness Reporting Big-Data-Analysis
- 5. OpenNebula used for all IaaS purposes OpenNebula in use since 2011 (2.x to 5.x) • Managed Hosting Usage • All DC locations managed by Nebula • Template based static virtual machines (!) – atypical use (one template == one VM) • Classical volatile virtual machines • Customer on-premise locations • Customer Self Service • Sunstone (VDC, Admin, Cloud Views) • Integrations • Integration into virtion’s self service customer portal • API integration • Scalable and automated services
- 6. Blockstorage based on Storpool DS Storpool Implementation • production since 2016 Implementation • 2 clusters – one per fire zone • Converged setup • >= 3 x SSD per server • >= 6 x HDD per server • Performance up to 200.000 IOPS and 2 Gb/sec bandwidth per cluster/client Main Use Cases • Volatile virtual machines (“Cloud Servers”) • High available servers (life migration, instant restart) • Scalable database and file services
- 7. Outlook/Future Planning Upgrade to OpenNebula 5.4.X (finally :D) Take newer StorPool Features into production • Bridge based replication for inter-firezone backup/replication • Replace SSD disks by Micron DC Max Container services • Rancher/Kubernetes Integration – currently test setup running • Automatic infra provisioning via ONE-Api Extend/automate monitoring • API based integration (Hooks etc.) • Dissolve antipattern of central monitoring in dynamic environments (switch to Prometheus, Sensu) Implement “EBS” storage • Integrated in Sunstone • Integrated into Customer Self Service • Using Storpools ISCSI-Implementation, e.g. for HA over different availability zones
