Why Autoscaling Management?

Common usage pattern of autoscaling is to scale in and out based on CPU utilization configured in K8s manifests or AWS Console. However, the engineers cannot imagine that how many Pods or VMs are scaled in and out with the CPU utilization. It is also difficult to predict the cost of autoscaling. Like IaC (Infrastructure as Code), the engineers need to manage the autoscaling as code as a declarative way. Wave Autoscale suggests the declarative way called "Scaling Plan as Code" to manage the autoscaling. The engineers can manage autoscaling configurations as code to understand the autoscaling behavior and predict the cost of autoscaling.

• Declarative Autoscaling: Wave Autoscale allows you to define autoscaling rules and resource scales declaratively using YAML, providing a more predictable approach to your budget and resource allocation.
• Beyond CPU Utilization Scaling: Traditional autoscaling often relies on simple metrics like CPU utilization. While it's an essential factor, it doesn't always provide a complete picture. Wave Autoscale considers a wider range of metrics, such as the size of the message queue, the status of the database, custom business KPIs, and more, allowing for a more nuanced and responsive scaling strategy.
• Simultaneous Scaling of Various Components: In modern architectures, scaling just one component like Kubernetes pods may not suffice. Related components such as serverless functions, databases, caching layers, and more must be scaled concurrently. Wave Autoscale provides simultaneous multi-scaling capabilities that cover a wide array of components, ensuring that all interconnected parts of an application are scaled in harmony, thus preventing bottlenecks.
• Cost-Effective Scaling: Unnecessary over-provisioning leads to increased costs, while under-provisioning can impact performance. Wave Autoscale continuously monitors and adjusts resources based on actual usage, ensuring cost-efficient scaling without compromising on performance.
• Business Event-Driven Scaling: Traditional autoscaling is often based on technical metrics like CPU utilization, which may not always align with business needs. Wave Autoscale allows you to define custom scaling plans based on business events, such as marketing campaigns, product launches, and more, ensuring that resources are allocated based on business priorities.

Wave Autoscale is designed to overcome these challenges, providing a more tailored and responsive approach to autoscaling that aligns with both technical complexities and business needs.

Use Cases

Kubernetes

• Scaling Replicas: Scaling a number of replicas of a deployment with metrics (not by HPA)
• CoreDNS Autoscaling: Scaling CoreDNS pods based on metrics
• Pod Right Sizing: Dynamically right-sizing pods based on metrics
• Istio Traffic Delay: When a service or a database is heavyly loaded, delay can be used to protect it from overload
• Istio Rate Limits: When a service or a database is heavyly loaded, rate limiting can be used to protect it from overload

AWS

• EC2 Auto Scaling: Scaling EC2 instances based on metrics
• ECS Auto Scaling: Scaling ECS tasks based on metrics
• Lambda Concurrency: Adjust reserved concurrency and provisioned concurrency dynamically to archive optimal performance and efficiency
• EMR on EC2: Configure the on-demand or spot instances, step concurrency, and more
• AWS WAF v2: Adjust the rate limit of a WAF rule dynamically based on metrics

And there are more use cases regarding Google Cloud, Azure, Cloudflare, and more.
