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.
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.
The cloud is the Internet.
Rather than a local or collocated server, your servers are located “somewhere” on the Internet.
You can specify a “region” for your servers.
The exact location of the hardware is unknown to you.
Pay for only the resources you use.
On-demand capacity.
Prepay reservations available.
Elastic capacity.
Scale your resources up and down based on usage requirements.
