Agility
Exploitation Requires Rapid Execution
Infrastructure management must be delegated

Composable Infrastructure
• Resource Pooling
• Rapid Elasticity
• Self Service
• Metering/Charge Back

Got It ... Why Go Private?
• Leverage existing infrastructure investment
• Customization and Control
• Regulatory/Security Requirements
• Cost

Doesn’t vSphere/XCP/XenServer already do that?

Software Is Eating Hardware
• Moore’s Law has pulled fault tolerance up the stack
• Commodity Hardware
• Reduced cost
• Services more workload types
• Dynamic resource allocation

What Is Apache CloudStack?
§Open source software that deploys and manages large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.
§CloudStack is a Top-Level Project at the Apache Software Foundation.

Anatomy Of CloudStack• Management Server Farm
• Management and provisioning tasks
• Zone
• Collection of pods, network offerings and secondary storage
• Pod
• Collection of clusters in the same failure boundary
• Cluster
• A grouping of hosts and their associated storage
• Hosts
• Servers onto which services will be provisioned
• Primary Storage
• VM disk storage
• Network
• Logical network associated with service offerings
• Secondary Storage
• Template, snapshot and ISO storage

Primary Vs Secondary Storage
• Random access read/write
• Changes often
• Zone Scoped
• Focused on throughput
• Write once/read many
• Append only
• Zone or Region Scoped
• Focused on reliability

What Is Riak CS?• Simple, reliable storage of large objects accessed using the S3 or Swift
API
• Objects are stored in buckets with a unique key
• Multi-tenant security model with per object ACLs
• Usage Accounting and Reporting
• Open Source (Apache2 Licensed)

Your Own Private S3
Wednesday, October 23, 13
Anatomy Of Riak CS
• S3/Swift API Proxy + Riak key-value store
• Peer-to-Peer Design: Any node can service any read or accept any write request
• Maintains multiple replicas (default 3) spread across multiple nodes
• Ops Friendly

Horizontally scaleable storage on commodity hardware

Riak CS Use Cases
• Secondary Storage for VM snapshot and template data
• Database Backup Storage
• Serving Static Content
• Application Log Storage
Wednesday, October 23, 13
Achieving Commodity Reliability
• Create a zone per power source/backbone network connection
• Establish independent primary storage in each zone
• Utilize intra-datacenter block-level replication between zones
• Distribute Riak CS nodes evenly across zones
