Kubernetes Autoscaling
Kubernetes auto scaling involves dynamically adjusting the number of running pods in a cluster based on current demand. This ensures that applications remain responsive while optimizing resource utilization. With the right configuration, auto scaling can help maintain performance during traffic spikes and reduce costs during low-traffic periods.
**Benefits of Implementing Auto Scaling**
The implementation of Kubernetes auto scaling brings a multitude of benefits to organizations. Firstly, it enhances resource efficiency by ensuring that applications use only the necessary resources, reducing wastage and lowering operational costs. Secondly, it improves application performance and reliability by adapting to traffic fluctuations, ensuring a consistent user experience even during peak demand. Moreover, auto scaling supports rapid scaling for new deployments, enabling businesses to respond swiftly to market changes without manual intervention.
**Challenges and Best Practices**
While Kubernetes auto scaling offers significant advantages, it also presents challenges that organizations need to navigate. One common issue is configuring the right scaling metrics and thresholds to avoid over-provisioning or under-provisioning resources. It’s crucial to thoroughly test and monitor these settings in a staging environment before deploying them to production. Additionally, consider using custom metrics that align closely with your application’s performance indicators for more accurate scaling decisions. Regularly reviewing and updating your scaling policies ensures they remain effective as application workloads evolve.
### Types of Auto Scaling in Kubernetes
Kubernetes offers several types of auto scaling, each designed to address different aspects of resource management. The most commonly used are Horizontal Pod Autoscaler (HPA), Vertical Pod Autoscaler (VPA), and Cluster Autoscaler.
1. **Horizontal Pod Autoscaler (HPA):** HPA adjusts the number of pod replicas in a deployment or replication controller based on observed CPU utilization or other select metrics. It’s ideal for applications with varying workloads, ensuring that resources are available when needed and conserved when demand is low.
2. **Vertical Pod Autoscaler (VPA):** VPA automatically adjusts the CPU and memory requests and limits for containers within pods. This ensures that each pod has the right amount of resources, preventing over-provisioning and under-provisioning.
3. **Cluster Autoscaler:** This tool automatically adjusts the size of the Kubernetes cluster so that all pods have a place to run. It adds nodes when pods are unschedulable due to resource shortages and removes nodes when they’re underutilized.
### Configuring Auto Scaling in Kubernetes
To leverage Kubernetes auto scaling effectively, you’ll need to configure it to meet your application’s specific needs. The process typically involves setting up metrics and thresholds that trigger scaling actions.
For HPA, you’ll define the target CPU utilization or other custom metrics that the autoscaler should monitor. VPA requires setting up recommendations for resource requests and limits. Finally, the Cluster Autoscaler needs to be linked with your cloud provider to manage node scaling efficiently.
It’s crucial to regularly monitor and adjust these configurations to ensure optimal performance, as application demands can evolve over time.
### Best Practices for Kubernetes Auto Scaling
Implementing auto scaling in Kubernetes is not a set-it-and-forget-it task. Here are some best practices to consider:
– **Understand Your Workloads:** Analyze your application’s workload patterns to choose the right type of auto scaling and set appropriate thresholds.
– **Use Custom Metrics:** While CPU and memory are common metrics, consider using application-specific metrics to drive more accurate scaling decisions.
– **Test and Monitor:** Regularly test your auto scaling configurations in a non-production environment. Continuous monitoring and logging are essential to catch and resolve issues early.
You can dynamically scale up or down any architecture component through autoscaling.
An example of a good use of autoscaling is as follows:
You may need additional web servers to handle the surge in traffic at the end of the day when your website’s load increases. Where does the rest of the day fit in? Your servers can’t sit idle during most business hours. Especially if you’re using a cloud provider, you want to optimize your environment’s potential costs. An autoscale allows you to increase the number of components during a spike and scale down during a regular period.
Example: Prometheus Pull Approach
There can be many tools to gather metrics, such as Prometheus, along with several techniques used to collect these metrics, such as the PUSH and PULL approaches. There are pros and cons to each method. However, Prometheus metric types and its PULL approach are prevalent in the market. However, if you want full observability and controllability, remember it is solely in metrics-based monitoring solutions.

These autoscalers rely on Kubernetes’ metric server for scaling up or down k8s objects.
Adopting Auto-scaling
Autoscaling is a mechanism that automatically adjusts the number of computing resources allocated to an application based on its demand. By dynamically scaling resources up or down, autoscaling enables organizations to handle fluctuating workloads efficiently. However, robust observability is crucial to harness the power of autoscaling truly.
The Role of Observability in Autoscaling
Observability is the ability to gain insights into a system’s internal state based on its external outputs. It plays a pivotal role in understanding the system’s behavior, identifying bottlenecks, and making informed scaling decisions regarding autoscaling. It provides visibility into key metrics like CPU utilization, memory usage, and network traffic. With observability, you can make data-driven decisions and ensure optimal resource allocation.
Monitoring and Metrics
To achieve effective autoscaling observability, comprehensive monitoring is essential. Monitoring tools collect various metrics, such as response times, error rates, and resource utilization, to provide a holistic view of your infrastructure. These metrics can be analyzed to identify patterns, detect anomalies, and trigger autoscaling actions when necessary. You can proactively address performance issues and optimize resource utilization by monitoring and analyzing metrics.
Logging and Tracing
In addition to monitoring, logging, and tracing are critical components of autoscaling observability. Logging captures detailed information about system events, errors, and activities, enabling you to troubleshoot issues and gain insights into system behavior. Tracing helps you understand the flow of requests across different services. Logging and tracing provide a granular view of your application’s performance, aiding in autoscaling decisions and ensuring smooth operation.
Automation and Alerting

Autoscaling Observability
Understanding Autoscaling
-Before we discuss observability, let’s briefly explore the concept of autoscaling. Autoscaling refers to the ability of an application or infrastructure to automatically adjust its resources based on demand. It enables organizations to handle fluctuating workloads and optimize resource allocation efficiently.
-Observability, in the context of autoscaling, refers to gaining insights into an autoscaling system’s performance, health, and efficiency. It involves collecting, analyzing, and visualizing relevant data to understand the application and infrastructure’s behavior and patterns.
-Through observability, organizations can make informed decisions to optimize autoscaling algorithms, resource allocation, and overall system performance. To achieve effective autoscaling observability, several critical components come into play. These include:
A. Metrics and Monitoring: Gathering and monitoring key metrics such as CPU utilization, response times, request rates, and error rates is fundamental for understanding the application and infrastructure’s performance.
B. Logging and Tracing: Logging captures detailed information about events and transactions within the system, while tracing provides insights into the flow of requests across various components. Both logging and tracing contribute to a comprehensive understanding of system behavior.
C. Alerting and Thresholds: Setting up appropriate alerts and thresholds based on predefined criteria ensures timely notifications when specific conditions are met.
Tools and Technologies for Autoscaling Observability
A wide range of tools and technologies are available to facilitate autoscaling observability. Prominent examples include Prometheus, Grafana, Elasticsearch, Kibana, and CloudWatch. These tools provide robust monitoring, visualization, and analysis capabilities, enabling organizations to gain deep insights into their autoscaling systems.
The first component of observability is the channels that convey observations to the observer. There are three channels: logs, traces, and metrics. These channels are common to all areas of observability, including data observability.
1.Logs: Logs are the most typical channel and take several forms (e.g., a line of free text or JSON). They are intended to encapsulate information about an event.
2.Traces: Traces allow you to do what logs don’t—reconnect the dots of a process. Because traces represent the link between all events of the same process, they allow the whole context to be derived from logs efficiently. Each pair of events, an operation, is a span that can be distributed across multiple servers.
3.Metrics: Finally, we have metrics. Every system state has some component that can be represented with numbers, and these numbers change as the state changes.
Understanding VPC Flow Logs
VPC Flow Logs capture information about the IP traffic going in and out of Virtual Private Clouds (VPCs) within Google Cloud. Enabling VPC Flow Logs allows you to gain visibility into network traffic at the subnet level, thereby facilitating network troubleshooting, security analysis, and performance monitoring.
Once the VPC Flow Logs are enabled and data starts flowing in, it’s time to tap into the potential of Google Cloud Logging. Using the appropriate filters and queries, you can sift through the vast amount of log data and extract meaningful insights. Whether it’s identifying suspicious traffic patterns, monitoring network performance metrics, or investigating security incidents, Google Cloud Logging provides a robust set of tools to facilitate these analyses.
Auto Scaling Observability
**Metrics: Resource Utilization Only**
– Metrics help us understand resource utilization. In a Kubernetes environment, these metrics are used for auto-healing and auto-scheduling. Monitoring performs several functions when it comes to metrics. First, it can collect, aggregate, and analyze metrics to identify known patterns that indicate troubling trends.
– The critical point here is that it shifts through known patterns. Then, based on a known event, metrics trigger alerts that notify when further investigation is needed. Finally, we have dashboards that display the metrics data trends adapted for visual consumption.
– These monitoring systems work well for identifying previously encountered known failures but don’t help as much for the unknown. Unknown failures are the norm today with disgruntled systems and complex system interactions.
– Metrics are suitable for dashboards, but there won’t be a predefined dashboard for unknowns, as it can’t track something it does not know about. Using metrics and dashboards like this is a reactive approach, yet it’s widely accepted as the norm. Monitoring is a reactive approach best suited for detecting known problems and previously identified patterns.
**Metrics and intermittent problems**
– The metrics can help you determine whether a microservice is healthy or unhealthy within a microservices environment. Still, a metric will have difficulty telling you if a microservices function takes a long time to complete or if there is an intermittent problem with an upstream or downstream dependency. So, we need different tools to gather this type of information.
– We have an issue with auto-scaling metrics because they only look at individual microservices with a given set of attributes. So, they don’t give you a holistic view of the problem. For example, the application stack now exists in numerous locations and location types; we need a holistic viewpoint.
– A metric does not give this. For example, metrics track simplistic system states that indicate a service is running poorly or may be a leading indicator or an early warning signal. However, while those measures are easy to collect, they don’t turn out to be proper measures for triggering alerts.
Latency & Cloud Trace
Latency, in the context of applications, refers to the time it takes for a request to travel from the user to the server and back. Various factors, such as network delays, server processing time, and database queries influence it. Understanding latency is essential for developers to identify bottlenecks and optimize their applications for better performance.
Google Cloud Trace is a powerful tool provided by Google Cloud Platform that allows developers to analyze and diagnose application latency issues. By integrating Cloud Trace into their applications, developers can gain valuable insights into their code’s performance and identify areas for improvement.
Developers need to capture traces to analyze application latency effectively. Traces provide a detailed record of a request’s execution path, allowing developers to pinpoint the exact areas where latency occurs. With Cloud Trace, developers can easily capture and visualize traces in a user-friendly interface.
Auto-scaling metrics: Issues with dashboards
Useful only for a few metrics
So, these metrics are gathered and stored in time-series databases, and we have several dashboards to display these metrics. These dashboards were first built, and there weren’t many system metrics to worry about. You could have gotten away with 20 or so dashboards. But that was about it.
As a result, it was easy to see the critical data anyone should know about for any given service. Moreover, those systems were simple and did not have many moving parts. This contrasts with modern services that typically collect so many metrics that fitting them into the same dashboard is impossible.
Issues with aggregate metrics
So, we must find ways to fit all the metrics into a few dashboards. Here, the metrics are often pre-aggregated and averaged. However, the issue is that the aggregate values no longer provide meaningful visibility, even when we have filters and drill-downs. Therefore, we need to predeclare conditions that describe conditions we expect in the future.
This is where we use instinctual practices based on past experiences and rely on gut feeling. Remember the network and software hero? It would help to avoid aggregation and averaging within the metrics store. On the other hand, we have percentiles that offer a richer view. Keep in mind, however, that they require raw data.
**Auto Scaling Observability: Any Question**
A: ) For auto-scaling observability, we take on an entirely different approach. They strive for other exploratory methods to find problems. Essentially, those operating observability systems don’t sit back and wait for an alert or something to happen. Instead, they are always actively looking and asking random questions to the observability system.
B: ) Observability tools should gather rich telemetry for every possible event, having full content of every request and then being able to store it and query it. In addition, these new auto-scaling observability tools are specifically designed to query against high-cardinality data. High cardinality allows you to interrogate your event data in any arbitrary way that we see fit. Now, we ask any questions about your system and inspect its corresponding state.
**No predictions in advance**
C: ) Due to the nature of modern software systems, you want to understand any inner state and services without anticipating or predicting them in advance. For this, we need to gain valuable telemetry and use some new tools and technological capabilities to gather and interrogate this data once it has been collected. Telemetry needs to be constantly gathered in flexible ways to debug issues without predicting how failures may occur.
D: ) Conditions affecting infrastructure health change infrequently and are relatively more straightforward to monitor. In addition, we have several well-established practices to predict, such as capacity planning and the ability to remediate automatically, e.g., auto-scaling in a Kubernetes environment. All of these can be used to tackle these types of known issues.
E: ) Due to its relatively predictable and slowly changing nature, the aggregated metrics approach monitors and alerts perfectly for infrastructure problems. So here, a metric-based system works well. Metrics-based systems and their associated signals help you see when capacity limits or known error conditions of underlying systems are being reached.
F: ) So, metrics-based systems work well for infrastructure problems that don’t change much but fall dramatically short in complex distributed systems. For these systems, you should opt for an observability and controllability platform.
Summary: Autoscaling Observability
Auto-scaling has revolutionized how we manage cloud resources, allowing us to adjust capacity dynamically based on demand.
