Real-time Monitoring of 5XX Errors using AWS Lambda, CloudWatch Logs and Slack

2023-04-28T01:34:19+00:00

Monitoring is the best friend of every system administrator. It gives visibility into what is happening on your application so that when an issue occurs, you or someone in your team could be alerted and do the necessary measures to mitigate it. However, this can only be as effective as the metrics you're keeping track of.  There are plenty of factors that can affect application performance. And while it’s difficult to stay on top of them all, there are certain metrics that are non-negotiable. Examples of these are CPU utilization, memory usage, disk space, disk usage, network throughput, and so [...]

Automatically stop non-production RDS databases with AWS Lambda and Amazon EventBridge

2023-05-26T05:23:48+00:00

Every AWS service offering comes with a pay-as-go pricing model, empowering businesses, small or large, to be flexible at experimenting and making changes as they build their products to market. This pricing model is similar to riding an Uber, where you only pay for the distance covered, or to electric bills where you’re charged based on actual energy consumption. Of course, the more devices you have running, the higher your monthly bill will be. Cloud computing, like any other utility, should be treated the same way.  Just as we are told to unplug appliances when not in use, removing/stopping unused [...]

How to Create Wait Conditions in a CloudFormation Template

2023-05-02T03:41:59+00:00

Wait Conditions, as the name suggests, is a tool used to control the order of creation of the AWS resources in a CloudFormation stack. It can pause the creation of a stack and wait for a signal to ensure that specific resources and configurations were properly launched before resuming the stack creation process. Use cases: For example, you want to make sure that a specific domain name is working before you can conclude that your application is indeed up and running. Or perhaps, you want to make sure that a particular stack resource can access an external API endpoint (or [...]
