Introduction

This is a proof-of-concept implementation developed to explore issues relevant to the redesign of Globo.com platform infra-structure.

Recently, the project http://orchestrate.io/ surfaced, and it seems to be related to these ideas..

Requirements for the New Platform

Backend as a Service (BaaS) composed by cloud-based RESTful services: * unified CMA * uniform access to all enterprise data (CMS,Search, Semantics) * authentication * authorization * billing

The new architeture should naturally lead to support for mobile apps

API Requests (80%) should respond below 20ms.

Objectives for this project

1. Design a draft of the new architecture for content publication. Define a first version of the interfaces and contracts between the several components of the architecture. There is no need for a complete implementation at the end of the project. Development of code will be done on-demand to validate concepts.

2. The design of the architecture will define the communication between the teams. We should be able to understand which stories are relevant to which teams.

The outcome of this project should be to deliver a draft implementation that does CMA+CDA for some content using the base elements of new architecture. The focus will be to elucidate doubts about the new architecture.

Desired features

• the definiton of data structures shoul carry its own documentation
• versioning (which level: API, resource, ...)
• Role-based access control (RBAC) model for authorization profiles

Configuration

We applied two configurations in ElasticSearch:

• elasticsearch/config/default-mapping.json
• elasticsearch/config/elasticsearch.yml

This files are inside the mythical-poc project tree, below config/elasticsearch. The goal of the configuration is to define that "uid" field always has exact match.
