Performance & Capacity planning
Nothing is more stressful than a phone call from the top management asking why an application is slow, or even worse, down. In a context of reduced IT budget, being compliant with your Service Level Agreements is more critical than ever.
Performance issues can have different sources:
- Your budget constraint forces you to limit the power of your machine. Hard capping, absolute capping and soft capping help you control your software expenses but require a tight monitoring if you want to protect critical workloads.
- Your recent updates or developments are not stable enough and generate loops and delays. In this context, you need to keep an eye on your mainframe behaviors to take corrective actions quickly if needed.
- Your performance needs were higher than expected. If you under-estimate the impact of new business activities on your infrastructure, your hardware might not be able to handle it. Hardware upgrades take time but your users might not have the luxury to wait.
