AWS Lambda: Synchronous vs Asynchronous Invocation

2024-07-17T03:30:08+00:00

You can invoke a Lambda function in two ways. Synchronous Invocation The first one is called Synchronous invocation, which is the default mode. Synchronous invocation is pretty straightforward. When you invoke a function synchronously, AWS Lambda waits until the function is done processing, then returns the result. Let’s see how this works through the following example: The diagram illustrates a Lambda function-backed API that is managed by API Gateway. When API Gateway receives a GET request from the /getOrder resource, it invokes the getOrder function. The function receives an event containing the payload, processes it, and then returns the result. [...]

Connecting your Lambda Function to a Private Database

2023-05-15T02:11:53+00:00

If you want your Lambda function to interact with resources (e.g., RDS database, EC2 instance) inside a private subnet, you won't be able to do so by default. The reason for this is that Lambda functions live in an isolated and secured VPC managed by AWS. This is why when you create a Lambda function, you don’t go through any networking configurations (VPC, subnet, ENIs), unlike when creating EC2 instances. Also, you cannot establish a VPC peering connection between the VPC where Lambda functions are run and the VPC where your private resources are located because the former is not [...]

How AWS IAM Handles Conflicting IAM Policies

2023-05-03T03:39:25+00:00

Overview When a user attempts an action in AWS, such as launching an EC2 instance or listing S3 buckets, AWS evaluates all involved IAM policies to determine whether to grant the request. Since IAM policies can be associated with various types of identities, the hierarchy of these identities influences the final permissions for a user. AWS IAM Policy Evaluation Flow Let’s break down the process of how AWS evaluates a request using the simplified version of the AWS flow chart below: 1. Default Deny AWS denies a request by default. For example, if your IAM user has no policies attached [...]

Understanding the IAM:PassRole Permission

2023-08-24T02:44:43+00:00

Introduction Many AWS services often require the use of an IAM role to execute actions on your behalf. For example, when you create a Lambda function, you assign an execution role to it. AWS can generate one for you automatically, and then you define the permissions you want it to have after. Most of the time, that's the case. However, there are instances when you might choose to associate an existing IAM role. In practice, we often concentrate on which permissions a user is allowed to perform and which are off-limits. But what's often overlooked are the IAM roles a [...]

Different Ways of Passing Parameters Securely in CloudFormation

2023-04-27T12:27:15+00:00

Introduction When writing CloudFormation templates, it's a security best practice to avoid hardcoding sensitive info, like client secrets, API keys, or passwords. Sharing templates with hardcoded details by mistake can put your infrastructure and data at risk. In this article, we'll explore different secure methods to pass parameters in CloudFormation templates. Using the NoEcho Attribute To avoid hardcoding parameters in your template, you can define them during stack creation using the Parameters section. However, these values will still be visible in plaintext in the Console. To mask critical data, consider using the NoEcho attribute. The NoEcho attribute offers a simple [...]

Automate Confluence Backup Using AWS Step Functions

2023-04-27T04:47:53+00:00

Introduction In this article, I'm gonna show you how you can create an automated Confluence backup in Atlassian using an AWS serverless solution. The motivation behind this article stems from a recent task I was working on a couple of weeks ago. My goal was to run a scheduled backup of Confluence data and export it to Amazon S3. Since Confluence backups are deleted 14 days after creation, it’s a good idea to have additional copies in a different location in case something goes wrong with your Confluence instance or if you need to restore data from a point in [...]
