Oracle Cloud Infrastructure (OCI) Operations Insights host capacity planning now supports OCI Compute instances. This new capability provides a holistic view of all OCI Compute instances across Oracle Cloud to help optimize Compute capacity.  Capacity planning is based on proactive planning,  capacity forecasting based on historical business trends, and infrastructure metrics.

Why capacity planning?

Providing sufficient resources is a cloud provider's responsibility. However, service owners in a cloud-scale environment,  still need to ensure that application stacks do not hit scalability limits. Managing scalability limits and efficiently using computing resources on the application level is still highly relevant, even on cloud infrastructure.

Over-provisioning all resources instead of keeping an eye on capacity is highly inefficient. Infrastructure cost is not zero and customers will find underutilized infrastructure quickly consuming the business margin and running out of capacity when application usage suddenly surges.

Operations Insights host capacity planning functionality is available to help customers analyze the behavior of OCI Compute instances that are under load. Capacity Planning functionality helps generate insights, makes recommendations based on trends, correlation, dependencies and saturation of constraints.

With the introduction of host capacity planning for OCI Compute instances, you can now analyze the resource utilization of these systems, and thereby identify the capacity requirements and perform capacity optimization using the built-in forecasting capabilities and model future capacity needs.

Enabling OCI Compute instances for capacity planning can be done from the Operations Insights administration page for hosts by choosing the telemetry type as Cloud Infrastructure. Use the compartment selector to choose the compartments where Compute instances reside.  OCI Compute instances are automatically listed to select and enable capacity planning on the hosts of your interest.

OCI Compute Instances Capacity Planning Use Cases

Forecast resource requirements

Use the Operations Insights host capacity planning functionality for OCI Compute instances to perform the following analyses:

  • Enterprise-wide analysis of resource utilization, capacity planning for OCI Compute instances
  • Improve resource utilization by identifying under and over-utilized resources
  • Identify systems projected to reach high utilization and deal with spikes in demand that are impossible to plan for ahead of time
  • Identify total lead time to expand capacity forecast (via machine learning) based on long-term historic data to project future resource growth
  • Track and avoid overspending due to excessive resource usage

You can drill down to individual OCI Compute instances and look at performance characteristics to analyze:

  • Top hosts by the resource type CPU and memory
  • The trend of resource utilization of your server targets, and forecast values for a specific time period.
  • Top server targets by a specific attribute. For example, you can group targets by operating system, or utilization level
  • Find low resource utilization servers
  • Top processes trend based on physical memory usage
  • Plan ahead using performance history and seasonality
  • Ensure service levels can be met over time
