A style of computing in which scalable and elastic IT-enabled capabilities are delivered as a service to external customers using Internet technologies.
What is ‘the cloud’?
An emerging IT delivery model —cloud computing—can significantly reduce IT costs & complexities while improving workload optimization and service delivery. Cloud computing is massively scalable, provides a superior user experience, and is characterized by new, internet-driven economics.
Prefer to call it x as a Service, where x is a consumable service resource that customers can buy in an on-demand fashion over the network. Cloud Services enable customers to procure infrastructure services where and when they need them and pay for them on a consumption based model
Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction

Summary
‘The cloud’ can mean different things- Shared computing resource among users with similar needs Natural means to improve operations and efficiency Services, platforms, infrastructure, networks
Agency can utilize cloud applications to consolidate data centers while improving data integrity and reducing cost
Data center networks continue to evolve towards embracing cloud topologies
Agency could decide to partition what’s owned and what’s bought based on application needs
You’re not alone in the public cloud……

Consolidation: Data centers and networks
Consolidation provides opportunity in increase efficiency to manage growth demands while lowering costs
• 100s of data centers to less than 10
• 10s of thousands of applications to a couple of thousand
• 20s of thousands of physical servers to under 10,000 virtual servers
ConsolidationData Center
Topology• Circuit consolidation
eliminates discrete networks and excess equipment
• Bandwidth consolidation to 10 G provides more flexibility
• Private WDM to bypass local loop and provide future scalability
Growth• Mission critical applications growing from 100s to 2-300s for
replication site-to-site • 10-20 PB total storage growing ~50% per year• 2-300s TB under data replication management with daily
replication growth from 10-15 TB now to 3-6 PB
