Automating Slack Notification for Route 53 TTL Changes

2024-06-25T00:36:30+00:00

Automating a Slack notification system for Route 53 with a 60-second TTL is intended to provide real-time alerts about DNS records with short TTLs. This setup ensures administrators receive quick notifications via Slack, enabling them to promptly identify and resolve potential issues. Through this proactive measure, the optimal performance and reliability of the AWS infrastructure are maintained. Moreover, this approach allows administrators to avoid potential problems by taking corrective actions promptly and minimizing any potential disruptions to services. Additionally, real-time alerts enable administrators to keep a close watch on DNS configurations, ensuring smooth operation and consistent performance of the AWS [...]

Unified Slack Automation for Purging the Cache

2024-05-15T11:29:22+00:00

Cached data can sometimes be corrupted, which can lead to performance problems. It can also prevent applications and websites from loading the latest version of their content. That’s why clearing cache is a must, not only does it resolve these issues, it also clears up space. Clearing cache is also a way to protect privacy since cache can hold sensitive information. About the task Currently, when purging the cache for both TD Portal and TD Main Site, 4 slack commands have to be used: For TD Portal: /clear-w3 portal /clear-fastcgi portal For TD Main Site: /clear-wprocket main /clear-fastcgi main Using [...]

Harnessing Real-Time Slack Notifications for Amazon RDS Event Monitoring

2024-05-10T01:13:18+00:00

Efficient management and monitoring of database instances are crucial for any business to ensure smooth performance. Amazon Relational Database Service (Amazon RDS) is a widely used solution for managing relational databases in the cloud. Staying informed about important events and changes within the database instances is a critical aspect of RDS management. Real-time notifications are vital to keep teams updated and responsive to these events. Slack is a popular platform for real-time notifications and seamless team communication and information sharing. Integrating Amazon RDS event notifications with Slack can provide teams with immediate visibility into database events, enabling them to take prompt action when required. Understanding Amazon RDS Event Notifications Amazon RDS [...]

Redacting PIIs Using S3 Object Lambda

2023-06-30T01:06:40+00:00

The Challenge Data privacy is a top priority for businesses, especially amid the rising global data regulations. One common challenge is ensuring sensitive data, like personally identifiable information (PII), remains protected when data is accessed or transferred. Imagine you have a bunch of employee profiles stored as CSV files in an S3 bucket. These profiles include sensitive information such as real names, social security numbers, and email addresses, along with non-sensitive data like job titles and office locations. Various teams within your company often need to access these files for their work. For instance, HR may need to understand the [...]

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 [...]

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 [...]
