Highlights of Monitorama PDX day 1

auto-create CloudWatch Alarms for APIs with Lambda

In a pre­vi­ous post we dis­cussed how to auto-sub­­scribe a Cloud­Watch Log Group to a Lamb­da func­tion using Cloud­Watch Events. So that we don’t need a man­u­al process to ensure all Lamb­da logs would go to our log aggre­ga­tion ser­vice. Whilst this is use­ful in its own right, it only scratch­es the sur­face of what …

You need to sample debug logs in production

It’s com­mon prac­tice to set log lev­el to WARNING for pro­duc­tion due to traf­fic vol­ume. This is because we have to con­sid­er var­i­ous cost fac­tors: cost of log­ging : Cloud­Watch Logs charges $0.50 per GB ingest­ed. In my expe­ri­ence, this is often much high­er than the Lamb­da invo­ca­tion costs cost of stor­age : Cloud­Watch Logs charges $0.03 …

how to do fan-out and fan-in with AWS Lambda

In the last post, we look at how you can imple­ment pub-sub with AWS Lamb­da. We com­pared sev­er­al event sources you can use, SNS, Kine­sis streams and DynamoDB streams, and the trade­offs avail­able to you. Let’s look at anoth­er mes­sag­ing pat­tern today, push-pull, which is often referred to as fan-out­/­fan-in. It’s real­ly two sep­a­rate pat­terns …
