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 [...]

My DVA-C02 AWS Developer Associate Exam Experience

2023-04-26T07:30:31+00:00

A few weeks ago, I took and passed the latest AWS Certified Developer Associate exam, DVA-C02. If you've already cleared DVA-C01 and intend to recertify, note that you can no longer book DVA-C01 exams. I suggest checking out this article I wrote a couple of months ago. This breaks down the changes you need to be aware of, and I’ve also shared my expectations for the DVA-C02 exam.  In this post, I'll be sharing my experience on the exam, discussing my thoughts on it, and providing tips and tricks that can hopefully help you get through it. Is DVA-C02 more [...]

Customize Your Invite Links with Amazon S3 Website Redirect

2023-04-26T07:40:26+00:00

If you use Discord, Slack, or Telegram, you're probably familiar with those long and complicated invite links used to join servers or channels. These links can be difficult to remember and may even discourage some people from joining. With URL redirection, you can create a custom and easy-to-remember domain name for your invite links. For example, you might use a domain like "discord.mycoolsite.com" that redirects to the invitation page of your Discord server, which might look something like this: "discord.com/invite/aabbCCDD". Inviting people thru a custom domain can reinforce your brand and make it easier for others to share and join [...]

Don’t Learn AWS Until You Know These Things

2023-05-24T11:39:31+00:00

Learning AWS is like trying to drink from a firehose. At least, that's how I remember it felt when I jumped into AWS years ago as a non-IT guy. I often bounced around between different articles and Youtube videos, struggling to make sense of all the concepts. One moment, I'd be focusing on an EC2 tutorial but then realize I needed to understand VPCs first, so I'd click over to a video about networking. Each time I tried to grasp a new concept, it would lead to another until I found myself lost in a maze of information. It was [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 2 of 2)

2023-04-27T03:15:40+00:00

Introduction In the first part of this post, we covered the concept behind event filtering in AWS Lambda and learned how it could help you save money by invoking functions only when necessary. Now it's time to put that knowledge into practice. In this part 2, we’ll see event filtering in action using Amazon Simple Queue Service (SQS) as the event source. Overview A user sends a JSON message to the SQS queue. Event source mapping picks up the message from the queue and evaluates it against the specified filtering criteria. Event source mapping invokes the Lambda function synchronously when [...]

Reduce The Cost Of Your Lambda Functions With Event Filters (Part 1 of 2)

2023-04-27T03:17:39+00:00

Problem statement You are primarily billed based on how long your Lambda functions run and how often it is invoked. This is why AWS Lambda is great for scheduled jobs, short-duration tasks, and event-based processes. But does this mean you shouldn’t use them for high-volume traffic applications? Well, the short answer is... it depends. Whether or not to use AWS Lambda for high-volume traffic workloads ultimately depends on the requirements of your application and the cost trade-off you're willing to make. Regardless, if you ever find yourself wanting to use Lambda in a high-activity application like stream processing, it’s good [...]
