• Wikipedia: computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services.
• Robert Carter, CIO of FedEx:”general purpose computing”. The ability to connect servers, networking, and storage that are “workload agnostic”– Jobs can shuffled around among company computers so machines are used as efficiently as
possible

Benefits• Generally lower cost for smaller footprints
• Speed to implementation
• Minimizes development and operations staff
• Allows IT to focus on company differentiators
• Standardizes business process with best in class approaches

Overall Project Timeline
The global rollout will service 7,700+ users.

Considerations:
• Community involvement during vendor evaluation
• Get Business, IT, InfoSec, Sourcing and Legal engaged as early as possible
• Understand what technology will be used in the cloud
• Identify system limitations, particularly our volumes and their capabilities
• Be firm with the Service Level Agreement
• Throttles are imposed in a multi tenant environment.
• Everything has a cost, regardless of location
• Plan on spending more resources on infrastructure and development than you think• The cloud tests environment capacity limits
• Understand how much data transformation the vendor is capable of performing

Advise:
• Approach a cloud solution like a major ERP implementation
• Understand Legal and Information Security requirements
• Validate SLAs in terms of performance and uptime
• Question maturity of Data Exchanges between clouds
• May require ETL efforts for Integration with other systems or cloud solutions
• Forced upgrades exist in most cloud solutions

HDSFedEx’s Hosted Database Services (HDS) is a set of standard hardware, software, and processes that provide OLTP database functionality that is: Homogeneous and predictable Low cost Pre-provisioned Highly available and scalable Able to support 90% or more of FedEx Services’
OLTP database needs
We will re-host approximately 400 databases in 5 data centers onto this standard architecture.
Approach
Migrate OLTP database workloads onto Oracle RAC (Real Application Clusters) running on Red Hat Linux v5.4
Scale out large workloads by expanding clusters to more nodes
Stack smaller databases together to achieve economies of scale
Take advantage of this extreme standardization to provide better service at a lower cost

HDS is based on the RAC Database Architecture

Overall Technical Architecture
Application server layer
Oracle Internet Directory (OID)
Small DB schemas
stacked on 4-node clusters
Larger DBs on their own 4-to-8 node clusters
High-volume apps use connections with node
affinity, making maximum use of local
cache
Thin JDBC connections
from apps are first routed
through an OID layer which directs the
connection to the proper cluster and
node
HDS DB clusters
SAN uses Oracle’s ASM for volume management03/11/2011Cloud Computing:Theirs, Mine and Ours

Automated Service Level Agreements HDS provides agreed-upon throughput and storage to the
application The application does not exceed transaction rates,
connection, or storage requirements Stacking of Multiple Schemas per Cluster
Security, space, backup, and recovery all managed at the Schema level
Enabled by the use of Oracle Services One database per cluster; multiple schemas per database
Design Features
Connection Abstraction
The application need not know where the DB server is located, who he is stacked with, how many nodes he is running on
Enabled by Oracle Internet Directory (OID) “Private cloud” computing
Rehosting
By use of DB replication (Oracle’s Goldengate), schemas can be relocated
Maintenance and upgrades can be done with near-zero downtime

What’s Different for the Developer?
• Application will connect to the database using Oracle Services
• The HDS database clusters will use GMT time
• We need to test failover in the clustered environment
• Larger database workloads will perform better if using node affinity

Results To Date
• 70 database schemas migrated onto 17 RAC clusters
• Our default cluster size is 4 nodes
• We will be stacking deeper, as our utilization on these 17 clusters is below 20%
• COTS software remains a challenge
