Kaytu enables engineering, DevOps, and SRE teams to reduce cloud costs by recommending optimal workload configurations based on actual-usage, ensuring savings without compromise. +
Kaytu recommends optimal workload configurations based on actual-usage,, ensuring savings without compromising reliability.
 - ## Overview - - - **Ease of use**: One-line command. Use without modifying workloads or making configuration changes. -- **Base on actual Usage**: Analyzes the past seven days of usage from Cloud native monitoring (CloudWatch), including advanced AWS CloudWatch metrics (where available). +- **Optimize**: Optimize AWS EC2 Instances & AWS RDS Instances/Clusters. +- **Base on actual Usage**: Analyzes the past seven days of usage from Cloud native monitoring (CloudWatch). - **Customize**: Optimize for region, CPU, memory, network performance, storage, licenses, and more to match your specific requirements. - **Secure** - no credentials to share; extracts required metrics from the client side -- **Open-core philosophy** Use without fear of lock-in. The CLI is open-sourced, and the Server side will be open-sourced soon. -- **Coming Soon**: Non-Interactive mode, Azure support, GPU Optimization, Credit utilization for Burst instances, and Observability data from Prometheus - +- **Open philosophy** Use without fear of lock-in. The CLI is open-sourced, and the Server side will be open-sourced soon. +- **Coming Soon**: Non-Interactive mode, GCP, Azure, GPU Optimization and Observability data from Prometheus ## Getting Started - ### 1. Install Kaytu CLI - **MacOS** ```shell brew tap kaytu-io/cli-tap && brew install kaytu ``` - **Linux** ```shell curl -fsSL https://raw.githubusercontent.com/kaytu-io/kaytu/main/scripts/install.sh | sh ``` - **Windows (and all Binaries)** Download Windows (Linux, and MacOS) binary from [releases](https://github.com/kaytu-io/kaytu/releases) - - ### 2. Login to AWS CLI - Kaytu works with your existing AWS CLI profile (read-only access required) to gather metrics. - To confirm your AWS CLI login is working correctly: - ``` aws sts get-caller-identity ``` [Click here to see how to log in to AWS CLI.](https://docs.aws.amazon.com/signin/latest/userguide/command-line-sign-in.html) - We respect your privacy. Our open-source code guarantees that we never collect sensitive information like AWS credentials, IPs, tags, etc. - ### 3. Run Kaytu CLI - ```shell kaytu ``` - -it will install aws plugin automatically. -now you can get optimizations by running: - +This will run and install any plugins. +To see how you can optimize EC2 Instances, run this command: ```shell kaytu optimize ec2-instance ``` - +Some optimizations such as RDS require login: ```shell kaytu login - +``` +For RDS: +```shell kaytu optimize rds-instance ``` diff --git a/cmd/root.go b/cmd/root.go index 152c59b..8d27390 100644 --- a/cmd/root.go +++ b/cmd/root.go @@ -192,13 +192,13 @@ func Execute() { err := manager.NonInteractiveView.WaitAndShowResults(nonInteractiveFlag, csvExportFlag, jsonExportFlag) return err } else { -
