IAS DMPHub discussion

Cloudfront / API Gateway - WAF can go in front of these. So probably don't need an ELB.
High Availability is offered in Application Logic Tier with how many containers you have, etc
Fargate is hourly charged, slightly higher than ECS.  do not have manage underlying Docker hosts, have to overprovision it.
can get away with running something not by the hour.

do work in stage - AWS Console is new 

start with database - Dynamo DB - get that figured.  Keep ELB and EC2 hosts

Parallel development in new 

Scalability requirements?  introduced recently - DMPTool is only service talking to it.  500 DOIs - not a lot of activity

data is metadata repository

Lambda gets charged as it executes

State maintenance can happen in S3

Dynamo DB is hugely complex; ACloudGuru has a great class on this
https://acloudguru.com/course/amazon-dynamodb-deep-dive

SSM Parameters are free

Cloudwatch can be annoying - python tools can provide tail -f functionality

All these services can log to cloudwatch.

lambdas log to cloudwatch by default

application cron jobs - AWS service to kick off jobs?  Cloudwatch events --> event bridge

ias-git-cloner

cloudwatch can be tied into alerts and notifications

UC3 Dev account - start to code it up into CloudFormation templates
Build components and add components to the template - automated deployment that makes everything from soup to nuts.

then deploy to staging and then to production in same account.  

https://github.com/cdlib/gitcloner - written in CDK --> generates cloud formation template

SA could recommend training and would factor this in
