Cloud Computing to Satisfy Peak Capacity
NeedsCase Study
What is Cloud?
Cloud computing is a model for enabling ubiquitous, 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. This cloud model is composed of five essential characteristics, three service models, and four deployment models. On-Demand Self Service Broad Network Access Resource pooling Rapid Elasticity Measured Service
Cloud DefinitionAccording to NIST
A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider
What is Cloud: On-Demand Self Service
Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations).
What is Cloud:Broad Network Access
The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand.
What is Cloud:Resource Pooling
Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time.
What is Cloud:Rapid Elasticity
Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
What is Cloud:Measured Service
A pragmatic approach is being developed to identify business value and not force-fit Cloud as a ”silver bullet.”
MetLife Cloud Approach
External Cloud is being positioned to extend our short-term, non-core compentency service offerings.
MetLife Cloud Approach
Internal cloud is being positioned to simplify and further automate capacity provisioning to speed time to market, enhance internal efficiencies and possibly compete with low cost, low support external offerings.
MetLife Cloud Approach
By developing separately but planning for an internal/external integration, we recognize the progressive nature of Cloud today.
Taking measured steps maximizes current value while stategically positioning MetLife to streamline operations and increase agility to respond quickly to market demands.
MetLife Cloud Approach
Replace high capital spend with low operational rent where appropriate
Speed to market over traditional provisioning for rapid project start, critical events, market agility and quick product evaluation

Use Case: HPC Grid
“(HPC) is the ability, using a set of open standards and protocols, to gain access to applications and data, processing power, storage capacity and other computing resources. A grid is a type of parallel and distributed system that enables the sharing, selection, and aggregation of resources distributed across multiple administrative domains based on their availability, capacity, performance, cost, and expected Quality-of-Service requirements.”
