Supporting the Shift to Cloud Inside,
Outside, and Across Organizations
Cloud is a model for enabling convenient, on-demand
network access to a shared pool of configurable computing
resources (e.g. networks, servers, storage, applications) that
can be rapidly provisioned and released with minimal
management effort or service provider interaction
Composition of two or more
clouds, private and/or public
Public
Cloud
Infrastructure made available
to general public or many
industry groups/customers
Infrastructure deployed and
operated exclusively for an
organization or enterprise
Private
Cloud Hybrid Cloud

39. Build on 20 Years of Storage Research
• APIs vs. mount points – “no slashes required”
– blocks vs. files vs. objects vs. “APIs”
• App-driven and policy-automated
– self-configuring, self-organizing, self-tuning, self-*
• Built in data services
– self-healing
• Unlimited namespace, dynamic
– billions and billions of objects, large and small
• Native multi-tenancy
– security/auth, monitoring, resource isolation

RAID

40. New Tools In the “Cloud”
Marketing buzz – IaaS –
Infrastructure as a Service
Marketing buzz – PaaS
– Platform as a Service
Marketing buzz – Big Data
