This document discusses several Amazon Web Services that can be used to launch services, including CodeDeploy for automated code deployments, Simple Workflow Service (SWF) for task coordination, CloudFormation for managing resources through templates, and Moonshot for deploying Ruby applications. It also describes using Cloud Database Service to allow users to provision databases on-demand with automated maintenance, and how its API was built with Grape and uses SWF and custom AMIs for workflows and activities.

1. Launching Services in
Amazon Web Services
James Armes, Cloud Software Engineer, Acquia

2. Code Deploy
– Automated code deployments.
– Agent is available for Linux or
Windows.
– Can be used for instances in AWS or
on-premises.
– Repeatable deployments.
– Rolling updates with rollback.

3. SWF
– State tracker & task coordinator.
– Promotes separation of control-flow
and business logic.
– Tasks can be run in parallel or
sequentially.
– Jobs can be picked by in instances
in AWS or on-premises.

4. CloudFormation
– Create/manage a collection of
resources.
– Create reusable templates.
– Avoids collisions.

5. Moonshot
– CLI Ruby gem.
– Pluggable.
– Currently requires ruby application
configuration.

6. Cloud Database Service
– Allow internal users to create
databases on-demand.
– Provide various service levels.
– Abstracts hardware and
implementation.
– Maintenance is largely automated.
– Resources are isolated in separate
VPCs.

7. Cloud Database Service (cont.)
– Custom API and worker AMIs.
– Bugsnag for reporting application
errors.
– Logs sent to Sumo Logic.
– StatsD/Graphite for performance
metrics.
– Deployments managed through
moonshot.

8. Cloud Database Service: API
– HTTP API built with grape.
– Public and internal endpoints with
access controls.
– HMAC authentication.

9. Cloud Database Service: Worker
– Picks up workflows and activities
from SWF.
– Built with aws-flow gem.
– Workflows utilize atomic activities.
– Activities are idempotent.
