List of the Top 4 Free Auto Scaling Software in 2025

The auto scaling capability of Google Compute Engine dynamically modifies the quantity of virtual machine instances according to changes in traffic or workload requirements. This functionality guarantees that applications perform at their best without the need for manual adjustments, while also minimizing costs by decreasing capacity during periods of low demand. Users have the ability to set scaling policies tailored to particular parameters, such as CPU usage or request frequency, allowing for personalized resource management. Additionally, new users are offered $300 in free credits, which allows them to experiment with and optimize auto scaling to suit their specific workloads.

StarTree Cloud functions as a fully-managed platform for real-time analytics, optimized for online analytical processing (OLAP) with exceptional speed and scalability tailored for user-facing applications. Leveraging the capabilities of Apache Pinot, it offers enterprise-level reliability along with advanced features such as tiered storage, scalable upserts, and a variety of additional indexes and connectors. The platform seamlessly integrates with transactional databases and event streaming technologies, enabling the ingestion of millions of events per second while indexing them for rapid query performance. Available on popular public clouds or for private SaaS deployment, StarTree Cloud caters to diverse organizational needs. Included within StarTree Cloud is the StarTree Data Manager, which facilitates the ingestion of data from both real-time sources—such as Amazon Kinesis, Apache Kafka, Apache Pulsar, or Redpanda—and batch data sources like Snowflake, Delta Lake, Google BigQuery, or object storage solutions like Amazon S3, Apache Flink, Apache Hadoop, and Apache Spark. Moreover, the system is enhanced by StarTree ThirdEye, an anomaly detection feature that monitors vital business metrics, sends alerts, and supports real-time root-cause analysis, ensuring that organizations can respond swiftly to any emerging issues. This comprehensive suite of tools not only streamlines data management but also empowers organizations to maintain optimal performance and make informed decisions based on their analytics.

AWS Auto Scaling is a service that consistently observes your applications and automatically modifies resource capacity to maintain steady performance while reducing expenses. This platform facilitates rapid and simple scaling of applications across multiple resources and services within a matter of minutes. It boasts a user-friendly interface that allows users to develop scaling plans for various resources, such as Amazon EC2 instances, Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas. By providing customized recommendations, AWS Auto Scaling simplifies the task of enhancing both performance and cost-effectiveness, allowing users to strike a balance between the two. Additionally, if you are employing Amazon EC2 Auto Scaling for your EC2 instances, you can effortlessly integrate it with AWS Auto Scaling to broaden scalability across other AWS services. This integration guarantees that your applications are always provisioned with the necessary resources exactly when required. Ultimately, AWS Auto Scaling enables developers to prioritize the creation of their applications without the burden of managing infrastructure requirements, thus fostering innovation and efficiency in their projects. By minimizing operational complexities, it allows teams to focus more on delivering value and enhancing user experiences.

StormForge delivers immediate advantages to organizations by optimizing Kubernetes workloads, resulting in cost reductions of 40-60% and enhancements in overall performance and reliability throughout the infrastructure. The Optimize Live solution, designed specifically for vertical rightsizing, operates autonomously and can be finely adjusted while integrating smoothly with the Horizontal Pod Autoscaler (HPA) at a large scale. Optimize Live effectively manages both over-provisioned and under-provisioned workloads by leveraging advanced machine learning algorithms to analyze usage data and recommend the most suitable resource requests and limits. These recommendations can be implemented automatically on a customizable schedule, which takes into account fluctuations in traffic and shifts in application resource needs, guaranteeing that workloads are consistently optimized and alleviating developers from the burdensome task of infrastructure sizing. Consequently, this allows teams to focus more on innovation rather than maintenance, ultimately enhancing productivity and operational efficiency.
