We recently had a webinar about getting started with a capacity management practice. The speaker was Renato Bonomini from Moviri.
Renato covered what you should think about when starting a capacity management practice, along with the initial steps you need to take. If you missed the webinar, you can listen to the recording by clicking here: http://event.on24.com/wcc/r/1239433/6D2E3095B74A17F297D250B6838CE58A
There were several questions asked during the webinar. We didn't have enough time to answer them all, so here are the complete set of questions with answers.
1. What can you say about your main competitors -- like SAS, VMturbo (turbonomics) and Cirba?
The vendors you mention are complementary to TrueSight Capacity Optimization. TrueSight Capacity is an analytics solution that is designed specifically for capacity management. Its strengths are in modeling, reporting, and visibility (views and dashboards). SAS is a general analytics tool. Cirba and turobonomics are both dynamic capacity optimization solutions. Their strength is in real-time workload placement that helps optimize use of virtual infrastructure.
2. What is the license model for TrueSight Capacity?
TrueSight Capacity Optimization is licensed by the endpoint (for example, by server, network port, etc.). There are three basic packages -- server, storage and network. Once you have a license for TrueSight Capacity Optimization, you can access free extensions in the TrueSight Capacity Marketplace. https://marketplace.bmc.com
3. How do you handle shared infrastructure? That one application will likely be sharing database, middleware, and even web tier with other applications. What meaningful information can you produce if you only collect data related to the one application?
With TrueSight Capacity Optimization, you can identify and view data for an application. You need to get the data collection process in place for your infrastructure. Then you can identify the data that is associated with a specific application. Reports and views can be created for applications. You can perform modeling, forecasting, and utilization reports and views by application. There are mainly two techniques:
- With workload characterization, you can directly measure the contribution of different applications.
- With multivariate analysis, you can estimate the contribution of one workload vs. the aggregate usage of the shared resource.
4. Are there references, books or courses in order to become a capacity planner?
BMC offers educational classes for using TrueSight Capacity Optimization. CMG -- Computer Measurement Group -- is a good source of information for capacity planners. Their conferences provide education sessions. CM also publishes newsletters and other publications related to capacity management. More information can be found on their web site. The CMG annual conference is November 7-10 and both BMC and Moviri will be there.
5. How does BMC do capacity management on a physical level?
Physical can mean a lot of things -- physical server, network, storage, power, cooling, etc. With TrueSight Capacity Optimization, you can look at all resources in the environment (physical and virtual). When analyzing resource usage, it is always a matter of supply vs. demand -- with resources being the supply side and workloads being the demand side.
6. What is the best way to convert the IT metrics into money language?
The best method of understanding the cost of doing business is to track the business service component against the overall cost. For example, reporting on a monthly basis the
average cost for transaction type and showing over 18 months the average cost of the transaction helps the business to understand cost of doing business. This cost is a combination of compute resources, operational practices (security, Disaster-recovery), power, facilitates and people resources to support the business service. Providing this level of transparency to the business opens the dialog Business and IT can have around the real cost and IT services provided. You can also perform business aligned capacity management. Working with correlations lets you build relationships between IT data and business data, or other non-IT data. Take one measurement and correlate to another – technical data correlated to business data. For example, through correlation analysis you can determine 10,000 customers an hour requires XX infrastructure. You can also track transactions to users to revenue.
7. How do you decide which business driver is more effective in deciding capacity issues?
Correlation analysis is the best method for researching business drivers that map to specific capacity limits or quotas. Some criteria for selecting good business drivers are:
- Measurements of “volume” (e.g. count of transactions in a period of time) are preferred to “concurrency” (that not everyone measures in the same way)
- Count of activities generated directly by user interactions (click-streams for example) are usually better measurements
- Metrics that can relate to business impacts e.g. number of orders) are better than technical ones (web hits)
- Less business drivers is better than more: measurements that are correlated by causation (e.g. a user login generates web hits on the login page that generates API calls downstream) should not be used at the same time, you just need the higher level measurement
8. Where can I best find resource material that will help me report from a financial point?
Providing awareness of the cost and method to recover expenses to support business services is extremely helpful in opening up the dialog between IT and business. Chargeback is a great practice to implement. Developing IT services using chargeable models that business can easily compare against outsourcers and/or cloud and SaaS providers means you can compete head to head with these providers. Without IT Service models with charges, the business can easily select outside IT services from outsourcers and cloud or SaaS providers with not understanding these providers do not provide the same level of services you are providing.
During Engage 2013, there were two sessions on Accounting and Chargeback
- The HCSC experience: http://www.slideshare.net/bmcsoftware/cost-transparency-with-capacity-optimization
- The Citrix Online experience: http://www.slideshare.net/bmcsoftware/how-citrix-effective-accounting-and-chargeback-with-true-sight-capacity-optimization
During CMG impact 2016 Conference to be help November 7-10, 2016 in La Jolla, California, Renato Bonomini from Moviri will host a tutorial session on Accounting and Chargeback: CMG-T: Accounting and Chargeback -- Benefits, Challenges, Implementation https://edas.info/p22005#S1569530668
