PCI-DSS compliant Elasticsearch, FluentD, Kibana, and Search Guard for security compliance. The setup utilized Docker Containers. Each service ran on a different virtual machine. The setup consisted of Ansible roles for two Elasticsearch Data Nodes, two Elasticsearch Master Nodes, two FluentD Aggregator Nodes, one Elasticsarch Cross Search Node, and a SearchGuard Container for managing security, all done as Docker containers.

This MariaDB Cluster Hardened service configuration provides security configurations for MariaDB. It is intended to set up production-ready MariaDB instances that are configured with minimal surface for attackers. Furthermore, it is intended to be compliant with the PCI-DSS v3.2.1.

Nginx 1.11.2 patched to work with Ey-balancer and delay modules. Included in the repository are:

EY-Balance: https://github.com/ezmobius/nginx-ey-balancer
Nginx-Delay: https://github.com/perusio/nginx-delay-module
OpenSSL: https://github.com/openssl/openssl

The setup is suitable for implementation of Java micro caching with low request-response answers. The Ey-balancer patch was created with the possibility to use the least_conn method of distributing incoming requests to the back end. This improved the response time in the critical part of the library.

If you are interested in using PowerShell Desired State Configuration to manage your web server configuration, the DSC Generator can help you get started. You can run the DSC Generator on an existing server, and it will generate a DSC configuration code for your IIS app pools, sites, and virtual directories. The DSC Generator will also generate Desired State Configuration for the Windows features on your IIS site.

This is a Ruby DSL and helper utilities for building CloudFormation templates dynamically.

Motivation:
CloudFormation templates often contain repeated stanzas, information which must be loaded from external sources, and other functionality that would be more easily handled as code, instead of configuration.

Consider when a user data script needs to be added to a CloudFormation template. Traditionally, you would rewrite the script by hand in a valid JSON format. Using the DSL, you can specify the file containing the script, and generate the correct information at runtime.

:UserData => base64(interpolate(file('userdata.sh')))

Additionally, CloudFormation templates are just massive JSON documents, making general readability and reusability an issue. The DSL allows not only a cleaner format (and comments), but will also allow the same DSL template to be reused as needed.

Blueprint looks inside popular package managers, finds changes and configures files, then archives software you built from source. It runs on Debian and RPM-based Linux distros with Python >= 2.6 and Git >= 1.7.

Blueprint reverse-engineers servers.
Easy configuration management.
Detects relevant packages, files, and source installs.
Generates reusable server configurations.
Converts blueprints to Puppet, Chef or CFEngine 3.
No DSLs, no extra servers, no workflow changes.
