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 [...]

Multi-Account Multi-Region Data Aggregation On AWS Config

2021-05-01T07:06:47+00:00

AWS Config is a service that tracks changes made to resources associated with an AWS account. This service can give you a detailed view of the resource configuration’s timeline so you can go back in time and identify when and what resource the change was made into. It also enables you to determine the overall compliance against the rules and configurations specified in your guidelines. This simplifies compliance auditing, security analysis, change management, and operational troubleshooting. Some Use Cases For AWS Config: Determining if CloudTrail is enabled on all regions. Checking if security groups have SSH port open from non-authorized [...]

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

2021-05-04T07:23:20+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 [...]

Amazon Aurora Machine Learning

2021-05-04T09:09:24+00:00

Amazon Aurora Machine Learning is a proprietary technology of Amazon that enables a native SQL user to integrate Machine Learning-based predictions to an application without knowing or understanding any machine learning algorithms. Machine learning heavily relies on datasets for it to work. You can say that data is the oil that keeps the engine of machine learning running. There is a massive amount of data generated every day. To give you an idea, according to this article, “By 2020, it’s estimated that for every person on earth, 1.7 MB of data will be created every second.”  Almost 2 MB of [...]
