Capacity management is an integral function of organizations running medium to enterprise multi-domain complex IT environments. Over the years, the shift from physical to virtual, to Cloud and now to DevOps/Microservices, has inevitably changed the perception of capacity management and whether it is still needed today.
View this webinar on-demand to learn why it’s necessary to invest in a toolset that underpins your capacity management process and why Syncsort’s Athene™ should be your tool of choice for delivering business and service assurance while controlling costs and meeting SLAs. We also explore key topics such as:
• What is capacity management
• How capacity management has evolved and why it’s as important for the Cloud
• How capacity management can encompass but differ from real-time monitoring
• Why we still need a mature capacity management process in place that should co-exist with your load and performance testing activities
• What benefits can be realized from implementing and maturing a capacity management process

4. ITIL
• The Purpose of Capacity Management is to provide a point of focus and management
for all capacity and performance-related issues, relating to both services and
resources, and to match the capacity of IT to the agreed business demands.

16. 1. We don’t need it for the cloud
• On-demand, infinite resources
2. “Clouds are elastic”
• Dynamic, automatic, prevention
3. Costs are always lower when using the cloud
• Fixed assets, Depreciation, Datacenter, Operations…
4. Architecture and planning become less important
• All you can eat perceptions, fire and forget approach
• Unless dedicated, multi-tenant model performance guarantees?

• Process underpinned by pliable IT infrastructure
• Digital service relationships
• Continuous change
• Quick to market
• Avoid slow and onerous processes
So…
• Where does Capacity Management fit into an
elastic environment?
• How does it need to change and adapt?

20. Performance Testing
• To check the performance of website servers, database, and network. If you are adopting waterfall methodology,
then it is important for you to check each time release of a new version. However, if you are using the agile
software development approach, then you need to test application continuously.
Load Testing
• To determine how many users the system can handle. You can also check out different scenarios that let you
focus on different parts of your system. Like the home page or checkout webpage on your website for web load
testing. It also helps you to determine how the load builds and sustains in the system.
Stress testing
• Website and app stress tests are significant before big events, e.g. ticket selling for a famous concert with high
demand of the people. So it is very important to test regularly to the capacity of the system endurance. This also
helps you to prepare for unexpected traffic spikes and gives more time and resources to fix any bottlenecks.

• Static, elastic, on-premise, hybrid or public cloud
• Legacy or DevOps
• Performance Testing and Capacity Management
• Should work in concert
• Combine Infrastructure and Application focus
• Implementing and maturing your Capacity Management process
• Where are you on the maturity scale?
• Provide centralization and focus across Business, Service and Component
• Strong toolset to underpin the process
