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

2022-05-30T06:57:48+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

2022-05-30T06:57:00+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

2021-05-01T07:38:04+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 [...]

Specifying Triggers for AWS Config Rules

2021-05-04T07:37:33+00:00

AWS Config allows you to set “rules” to evaluate configuration settings on your AWS resources. The result of these rule evaluations are then displayed on the AWS Config web console. You can control the frequency of rule evaluations by AWS Config by specifying a trigger. A trigger refers to the method of evaluation for your config rules. There are two types of triggers to select from when creating a rule. 1. Configuration Changes When “configuration changes” is enabled, AWS Config will evaluate the config rule when specific resources are created, changed, or deleted. In simple terms, as the name implies, [...]

Symmetric vs. Asymmetric CMKs

2021-11-21T03:33:03+00:00

Even before the Internet, the security, privacy, and integrity of information have always been the top concern of institutions like banks, hospitals, and universities. Nobody wants their personal information (name, address, credit card number, etc.) to be exposed in public for anyone to use. Imagine signing up on your favorite social media website, and after a few days, somewhere on the globe has been using your profile and pretending to be you without you knowing! Or maybe you’ve been using your credit card for shopping online and suddenly, your bank is sending you email reports for fraudulent activities on your [...]

AWS Managed Policies For Job Functions

2021-04-19T10:55:09+00:00

AWS managed policies for job functions are policies that contain sets  of permissions required for a specific job function or role (especially in the IT industry). It is designed to simplify the creation of policies by combining the permissions for many services into a single policy. You can attach these policies for job functions to any group, user, or role.  To further understand this, let’s consider the scenario below: Mikee is the new database administrator of a social media startup that leverages on Amazon Web Services. She was assigned to configure the minimum set of permissions in IAM so she [...]
