Overview

Voluntarily has various service endpoints Managing Access to open platforms and this page gives a high level overview on how these are set up.

...

Things missing here:

• cloudflare setup

Monitoring and Metrics

Have a dashboard setup to view application and infrastructure usage data, telemetry.

High level Design

(in progress)..

Infrastructure

• load Balancers

• Fargate Service

• CPU/Memory Usage

Current Setup:

Cloud Watch dashboard setup for ELB and ECS services used by vly. Enabled ‘container insights’ for ECS services. View sample dashboard: https://ap-southeast-2.console.aws.amazon.com/cloudwatch/home?region=ap-southeast-2#dashboards:name=vly-services;accountId=585172581592

ToDo: Team consensus and understanding on setup. Naming. Add further missing information, check existing setup, compare differences and fix what is needed.

Application

• Application metrics

• tracing?

• Health end points

• separate Test Suite/service deployed for regular(5 min interval?) app endpoint checks?

Current Setup:

Notifications

• possibly start with slack channel notifications

• aws infrastructure can utilise cloudwatch and SNS

Current Setup:

Cloud watch Alert → SNS Topic → Lambda function to push alert to Slack channel ‘#notifications’

ToDo:

• Refire alert if it is not addressed

• serverless setup for lambda function code, currently its just a quick demo

Logging

thoughts:

• configure log levels based on env var so just update env var to DEBUG and get all logs

• log rotation?

• standardised log solution

Tracing

thoughts: (do we want this?)

• standardised distributed trace solution?

• i have previously worked with Jaeger-open tracing standard - OpenTracing standard
