A rapidly evolving startup is preparing to deploy an application that will undergo frequent iterations with multiple deployments expected each week. The application requires complex configuration, which includes coordinated updates across compute, database, and networking services. To ensure the most efficient deployment process for this scenario, which of the following methods should the startup employ?
Repeatedly use the individual service consoles to configure and manage each service manually for every deployment.
Implement regular deployments using a container orchestration service like Amazon ECS without applying broader IaC strategies.
Develop a series of manual scripts for configuring each service and run them sequentially for every update.
Leverage an Infrastructure as Code service such as AWS CloudFormation to codify and automate the complete deployment process.
