These are the areas of expertise that CMG builds, fosters and is chartered to advance:

PERFORMANCE MANAGEMENT
Managing performance involves monitoring and tuning. Monitoring a system’s behavior utilizes a variety of tools and procedures to categorize, identify and report on the system with the goal of being proactive about performance issues. Tuning a system involves the skills required to change the system in order to improve its performance.

CAPACITY PLANNING
Capacity Planning provides a corporation with the ability to plan accurately for future IT purchases. The initial process involves a forecast of the corporation’s workload to project future system requirements. This involves understanding how the workload on the system correlates to the business and how both of those things will change in the planning horizon. The next process involves understanding of how various purchasing decisions may meet those projected requirements. This can be accomplished through a variety of procedures including modeling and benchmarking.

MODELING, MATH AND STATISTICS
System models are a tool commonly used for managing the computing resources for an enterprise. The creation and use of models are addressed in this subject area. Models can employ either simulation or analytical techniques.

SOFTWARE PERFORMANCE ENGINEERING
Most often, the biggest performance improvement gains achievable are those that address the design of the applications running on your systems. However, once an application is designed, changing it is nearly impossible and very expensive. This subject addresses the set of skills necessary to incorporate performance into the application design and build processes so that performance is not an after-thought.

STORAGE
Storage systems can be one small set of tape drives, one disk subsystem or a complex, geographically dispersed, networked system. Wherever information is stored, that is part of this topic.

MANAGEMENT AND CHARGEBACK
Managing computing resources involves significant monetary investment. The tools and techniques used for keeping track of this investment comprise this subject. Making this information useful for all the decision makers in a corporation is known as the set of practices called ChargeBack.

NETWORK
The power of connectivity has eclipsed the power of the processor, leading to such incredible phenomena as the Internet. All the components of the Internet, from hubs, routers and switches to the systems and architectures (DNS, IP, proxies, redirection, content distribution and delivery, etc.) that make up the Internet are covered in this subject area.
