Cheapest hosting costs at AWS to migrate

For migrating your 2 commercial web and 3 simple WordPress sites from Bluehost to AWS with cost optimization in mind, here are the most cost-effective options:

For your WordPress sites:

• Host the static content on Amazon S3, which is highly cost-effective for static website hosting
• Use Amazon CloudFront as a CDN to improve performance while keeping costs low
• For the WordPress backend, consider Amazon Lightsail which offers simple, pre-configured instances specifically designed for WordPress at predictable, low monthly costs

For your commercial web applications:

• AWS Elastic Beanstalk would be a good option as it simplifies deployment and management while allowing you to choose appropriate instance sizes
• Implement auto-scaling to ensure you only pay for resources you actually need
• Choose the right EC2 instance types and sizes based on your actual workload requirements

Cost optimization strategies:

• Take advantage of the AWS Free Tier offerings during your migration phase
• Implement automated start/stop schedules for development and testing environments
• Use proper tagging to track and manage your AWS spending
• Set up AWS Budgets to get alerts when costs exceed predefined thresholds
• Regularly review your usage with AWS Cost Explorer to identify optimization opportunities
• Consider Savings Plans or Reserved Instances once your usage patterns become predictable

Remember to continuously monitor and adjust your resources as your applications' needs evolve to maintain optimal cost efficiency.
