Provide an Amazon AMI for XWiki to allow starting XWiki on Amazon EC2 easily.

See also this existing ticket.

The main goal is to offer more ways to distribute XWiki to make it more attractive to all kinds of usages, and thus increase our Active Installs.

Currently, XWiki offers two types of installations for Xwiki Software: One for Demo and one for production See this link. Also, there are two versions available: 12.10.5 which is a stable release, and the other is 13.1 which is up to date and latest.

Currently, Xwiki support HyperSQL, MariaDB, MySQL, Oracle, and Postgres for Database Management. Currently, AWS natively supports MariaDB, MySQL, PostgreSQL, and there's support for a fully managed Database system called Aurora which again natively has compatibility with both Postgres and MySQL. You'd have to deep dive into AWS Resources and see what would be the best way to implement this. You might want to look at RDS and Aurora for the same.

There are 6 ways to install XWiki all of which can be found here. It'll be good to have an AMI for each type of installation. You'll have to create a Launch template and Bootstrap scripts and install the required dependencies on bootup. 

The EC2 instance type can be left out to be chosen by the installer as per their requirements. Considering the long-term maintainability of the AMIs, it'd be nice to have an automated way to update the AMIs when a newer version is released. You can use and look into AWS CDK for managing Infrastructure as a Code so we can keep a check on the work you do as you progress through different phases of GSoC and you'll have to release a working image or version before each phase end. You will also have to document the progress on the wiki. 

Your communication with the community would be one of the significant factors we'd consider while considering your proposals. I do not wish to include lots of details around AMIs here and will let you be creative in choosing your approach towards solving this and would love to see that creativity in your proposals. emoticon_smile
