data center grows

When target is added, define its

operational and business properties

and thats it!

Goals

Provide greater automation and agility, driving

efficiency and lowering cost

Enable transformation of the entire IT into Cloud

Not build more pockets of automation

Be broad enough to cover typical enterprise landscape

Reduce complexity, not increase it

Cater to all personas and roles within an enterprise

Cloud consumer, Cloud administrators, Developers, Business

Sponsors

New solution must be designed in Cloud context

Summary report

Trending report


Capacity Planning

Challenges

Capacity prediction

When will I run out of capacity for key resources?

Efficient resource utilization

Do I have a well-balanced configuration?

Am I using resources efficiently?

Quality of service (QoS) assessment

How many outages occurred in last 6 months?

How many times SLAs were violated in the last week?

Benefits

Make purchases only when necessary to meet demand

Consolidate or repurpose underutilized systems

Improved QoS


Consolidation Planner

Enables efficient use of resources by identifying

consolidation opportunities

Analyses historical utilization and recommends

consolidation plan

Consolidation benefits

Reduced server maintenance costs

Reduced administration costs and complexity

Reduced energy and floor space costs

Reduced capital expenditures on servers

Improved physical and network security

(smaller perimeter)

Simplified disaster recovery plans

Consolidation can be physical (consolidation of

underutilized servers), or virtual (migration of servers

to virtual machines)
