• The new integration with Tivoli Service Automation Manager (TSAM) allows you to transform dormant or underutilized compute resources into powerful workload computing agents.

• Using TWS and TSAM together, you can provision resources on an as-needed basis to help meet scheduling deadlines for critical workloads, without user intervention!

Introduction

IBM Tivoli Service Automation Manager offers:• Standardization and automation for deployment and management of IT services• Improved quality and cost per IT service• Smoother transition from pre-production to production• Process governance• Reduced manual (and costly) interventions• Reduced skill requirements • Fast Deployment of IT services

Tivoli Service Automation Manager

Workload Automation in the “Cloud”

Scenarios Example Workload Execution environment – Every month-end a Bank needs

to create a set of Reports. Reporting application runs on a Linux servers pool that should be created on month-end and released after its usage

Elastic scaling – Reports for private-banking accounts must be deliverd by 8:00 AM the first month-day; in case of potential delays, customer wants the envirornment to be automatically boosted to meet this SLA

Deliver quickly an environment with tight specifications on installed stack, and announcement in a managed environment.

Solution Create a Workload Automation Execution service in Smart Cloud

Provisioning (SCP) that: Allows to model, reserve and automatically provision “WA-ready execution

environments” in a cloud Automatically configure a scheduling sandbox in an existing TWA environment (or

provision a new one) for managing the new environment

Automatically provision or activate additional VMs in the SCP environment in case of jobs delay in TWS

Cloud Computing: Elastic Scaling

8

The elastic scaling is the ability to provision resources in response to changes in demand.

Scale up when demand increases

Scale down when demand subsides

«Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically reconfigured to adjust to a variable load (scale), allowing also for an optimum resource utilization.»

[Vaquero et al, 2009]
