6. Why Portworx?
Tight Kubernetes Integration and DevOps driven automation
● All operations driven through the scheduler
● Extensive OpenStorage API to use for your “Infrastructure as Code Platform”
Very High Application Density Support
● 1000 Nodes per cluster, 100K virtual volumes per cluster, 1000 volumes per host
● No extra cloud provider cost per virtual volume
● High IOPS and bandwidth evenly distributed even to small volumes
Multi AZ and Multi Cloud Application Level Availability
● Every Portworx volume is available in any Availability Zone
● Global volume namespace - Available even across different Cloud Providers
● Application level RTO on failover is in seconds
Application Aware Volume Provisioning
● Application Aware Group Storage Features (Snaps, Encryption, DR per volume groups)
● Multi Container Volume Provisioning - An application is not just one container
Data Workflow Management
● Blue Green deployment support
● Application level migration between clusters and clouds

Top Use Cases for Stateful Containers + Portworx
Databases
Enable density and HA: run multiple databases (SQL, NoSQL) on any
infrastructure, with containerized volumes that are isolated, backed-up off-site,
and encrypted.
Data
Processing
Process faster: create and access TBs of storage in seconds on any compute
server in the cluster, enabling flexible and faster data processing.
Content
Management
Scale easily: run multiple containers with files shared on a common volume, in
order to scale-out more densely and with less to manage.
DevOps
Toolchain
Integrate workflows: share common libraries as snapshots and backup to off-site
s3, allowing for easier workflow integration and always-on data protection.
Big Data
Share infrastructure: run compute jobs with data converged and stored in
containerized volumes, enabling other workloads on the same infrastructure.

8. Open Source
OpenStorage.org
Scheduler Data Layer: OpenStorage is a massively scalable data layer for
Containers and Schedulers like Kubernetes and Mesosphere:
https://github.com/libopenstorage
LCFS
Data Path: LCFS provides core data path functionality for Docker images.
Check it out on https://github.com/portworx/lcfs
PORX
Bundled Data Services: Try out the Portworx community edition at

Torpedo
A test suite for validating storage solutions for Linux Container Orchestration
tools
CSI
Container Storage Interface. Standard Storage API between all Schedulers
and all Storage Providers
STORK
Cloud Native storage orchestration runtime scheduler plugin to translate a
orchestration decisions into something upon which an external cloud native
storage solution can act. Extends Kubernetes with more stateful awareness
of the underlying storage provider, it's capabilities and state.
