+
+# Infrastructure Provisioning
+
+## MageSuite ecosystem
+
+Altough it's possible to use this code to hosting any Magento based shop,
+some features are only avaialble (and tailored for) [MageSuite](https://magesuite.io/) ecosystem.
+
+## Cloud infrastructre
+
+Currently the full feature set is only available when using AWS as the cloud platform, however, 
+it's possible (and tested) to use this code to provision any CentOS 7 VM including local development environment. 
+
+_PS There's also an [experimental docker container](https://github.com/mageops/docker-centos-systemd) which can 
+be fully provisioned by this code and run a full CentOS installation like a VM. This is intended to be used 
+only for local development though and not yet supported_.
+
+## Feature highlights
+
+- Out-of-the-box autoscaling
+- Zero-downtime deployments<sup>1</sup>
+  - Nodes are warmed up when new code is being deployed before being attached
+    to the varnish load-balancer to avoid cache generation penalty after traffic hit
+- Varnish caching tailored for Magento with multiple configurable custom features
+- Redis Magento cache backend with 
+  - Separate redis instance for session storage 
+- Customizable multi-website / multi-shop deployments
+- Letsencrypt certificates support
+- Cloudfront CDN
+  - Media stored on S3
+  - Seamless image optimization via Lambda@Edge (with webp support)
+- Support for file sharing across nodes via AWS EFS
+- Per path pattern customizable PHP limits
+- Customizable request throttling (rate-limiting)
+- On-demand import instance 
+  - EC2 instance started for scheduled imports automatically and terminated
+    once the import is finished
+  - Allows to use a different instance type for heavy scheduled imports
+    and perform them without disrupting the site performance for end-users
+- Customizable rules for routing traffic to separate set of special purpose extra-instances
+  - Routing rules based on user-agent and request path patterns
+  - Useful for processing heavy workloads without disrupting shop performance (e.g. ERP Magento API integrations)
+- Magento queue consumers support with RabbitMQ and supervisord
+- Logs pushed to CloudWatch with slack notifications for critical errors
+- VPC and SG-based network communication rules allowing internal service communication 
+  strictly on a need-to basis
+- ... any many more!
+
+<sup>1</sup> Needs at least 2 app nodes and requires certain MageSuite extensions. Also it might not be
+possible depending on changes in relation to previous release in the code being deployed (DB migrations, ...).
+
+## Initial open-source release
+
+The code has been cleaned up and all commits squashed for the first public release.
+
+The previous internal repository had **2000+ commits**, **300+ merge requests** created by
+10+ contributors across **3+ years of development**.
+
+The current state is a result of hundreds of hours of meetings, debugging, brainstorms
+investigations and combined expertise of all our developers, PMs and clients. 
+
+A lot of the solutions are tailored for solving real-world problems and use-cases that came
+up when hosting and maintaining highly-customized Magento-based shops. The value of such
+experience-based solutions cannot be overestimated. It wouldn't be possible to come up and 
+design all of these tiny details form scratch without having went through the all of problems first-hand.
+
+## Documentation
+
+At the time of open source release most of the documentation was scattered 
+across internal creativestyle services thus any leftovers have been removed 
+to avoid confusion. New documentation will start appearing shortly as part 
+of this repository succesively.
