Where can I find a tutorial on elastic beanstalk that reflects 100% the current state of the platform

I understand your frustration with finding up-to-date tutorials for AWS Elastic Beanstalk. While it's true that some documentation may not always reflect the most current state of the platform, AWS does provide some relatively recent and relevant resources for learning about Elastic Beanstalk.

AWS offers official tutorials and sample applications that are designed to demonstrate the use of Elastic Beanstalk with various web frameworks and technologies. These include tutorials for deploying applications built with popular languages and frameworks such as Ruby on Rails, PHP, Node.js, Python, and .NET Core.

Additionally, AWS provides more complex sample applications available as open-source projects on GitHub. These samples showcase the use of additional web frameworks, libraries, and tools in conjunction with Elastic Beanstalk. Some examples include:

1. A tutorial for setting up a load-balanced WordPress installation
2. Instructions for deploying a load-balanced Drupal environment
3. A sample application called "Scorekeep" which demonstrates a RESTful web API using the Spring framework and AWS SDK for Java

These resources are designed to provide practical, hands-on experience with Elastic Beanstalk and often incorporate best practices and integration with other AWS services.

While it's true that the cloud computing landscape evolves rapidly, and documentation can sometimes lag behind, these official AWS resources are generally maintained and updated to reflect significant changes in the platform. However, it's always a good idea to cross-reference the information with the latest AWS documentation and consider any recent updates or changes to the service that may not yet be reflected in tutorials.

If you're looking for the most up-to-date information, you might also want to check AWS's official blog posts, recent re:Invent conference presentations, or the AWS Elastic Beanstalk release notes for the latest features and best practices.
