An Ocean system as viewed from the Ocean Tool. video

Ocean is a synergy of three things:

  • A fast, powerful Ruby on Rails programming framework and microservice architecture where all the difficult problems already have been solved for you: authentication and authorisation, users, roles, groups, aggregated logging, aggressive caching, flooding protection, string translation, asynchronous job handling, and much more: all you need to create your scalable application. Yet Ocean is a thin layer which never gets in your way. You can just get on with the task at hand.
  • Complete development pipelines in the cloud, implementing continuous integration and continuous delivery for each service.
  • A modern, extremely scalable, highly available, resilient, highly secure and autoscaling architecture following best practices for the cloud, designed by a certified AWS Solutions Architect.

Ocean can be set up on AWS in half an hour and is equally suitable for small startups using Ruby on Rails as for large enterprise-level systems. Start small and cheap and grow painlessly in an massively scalable architecture.

Features at a Glance

  • Complete foundation on which to base any web or JSON API application
  • Micro service HTTPS architecture in the Amazon cloud
  • Extreme scalability
  • Built for high security, resilience and robustness
  • Aggressive, stringent caching model reduces costs and increases speed
  • REST, JSON, UTF-8
  • HATEOAS hypertext conventions reduce coupling to a minimum
  • CloudFormation: infrastructure as code
  • AWS CodeBuild, CodeDeploy, CodePipeline: AWS native DevOps and CI
  • Ruby on Rails used the right way for massive scaling
  • Authentication is based on DynamoDB to handle any number of logins per minute
  • Atomic level authorisation (per HTTP method)
  • Asynchronous Job queues for high scalability and robustness
  • Aggregated high-speed real-time log for all services
  • Scalable email handling
  • Auto-scaling on load and/or weekly schedule
  • Complete, test-driven TDD iterative development pipeline
  • Continuous integration
  • Continuous delivery and/or deployment
  • Rolling In Place and/or Blue/Green deployments
  • Front-end matrix testing
  • Multi-variance testing and delivery
  • World-wide delivery of media through S3 and CloudFront
  • Multi-language text handling
  • Live metrics are part of the resources (instances, load balancers, etc)
  • Monitoring and automated handling of malfunctioning instances
  • Semaphores and automatic operator email notification
  • Guppies of Disarray (our take on Chaos Monkeys)
  • Web based Admin Client
  • Ocean Tool – a 3D client for Ocean
  • Easy set-up
