• 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

Cloud Computing: Public


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

Design Features



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
