Aspect | Description | Best Practice |
---|---|---|
Avoiding over-provisioning and under-provisioning | Track provisioned resources (e.g., CPU, memory, storage) and compare them to actual usage. Analyze trends to identify patterns and adjust autoscaling configurations accordingly | Monitor provisioned resources |
Continuously refining and optimizing autoscaling configurations | Work closely with development teams, business owners, and operations staff to understand their input and expectations regarding autoscaling | Collaborate with stakeholders |
Defining scaling policies and rules | Develop scaling policies that define when and how to scale, considering factors like time of day, day of week, and upcoming events. Policies should also address cool-down periods to prevent frequent scaling | Create scaling policies |
Handling seasonal traffic and variable workloads | Determine regular patterns in workloads, such as daily, weekly, or monthly cycles, and configure autoscaling to accommodate these patterns | Identify recurring patterns |
Integrating autoscaling with continuous integration and delivery pipelines | Treat autoscaling configurations as code and integrate them into your CI/CD pipeline. This ensures that updates go through testing and validation before deployment | Incorporate autoscaling into CI/CD |
Monitoring and analyzing autoscaling performance | Regularly collect and analyze key performance indicators (KPIs), such as response time, error rate, and resource utilization, to assess autoscaling effectiveness | Collect performance metrics |
Right-sizing containers and pods | Ensure that each container and pod has accurately defined resource requests (CPU, memory) and limits to avoid over-provisioning or under-provisioning. This helps maintain application performance and prevents wasteful use of resources | Use accurate resource requests and limits |
Selecting appropriate autoscaling algorithms | Different autoscaling algorithms suit different workload types. For example, for stateless web servers, use a simple algorithm like Scale out/in by quantity. For stateful apps, consider using more advanced algorithms like Target tracking or Queue depth | Choose algorithm based on workload type |
Setting up horizontal and vertical autoscaling boundaries | Establish clear minimum and maximum scales for both horizontal (number of replicas) and vertical (container sizes) autoscaling dimensions. This ensures that autoscaling actions stay within acceptable bounds and prevent unexpected behavior | Define scaling boundaries |
