Update: On July 15, 2021, AWS Lambda will deprecate Python 2.7 as a supported runtime, formally ending our Python 2.7 support. The Lambda function and CloudFormation in this blog post have been updated to use Python3. You can use AWS Global Accelerator to get static IP addresses that act as a fixed entry point to […]

AWS Transit Gateway simplifies your network and puts an end to complex peering relationships. It acts as a cloud router and scales elastically based on the volume of network traffic. It can centralize connections (known as attachments) from your on-premises networks, and attach to Amazon Virtual Private Clouds (VPC) Virtual Private Networks (VPN), AWS Direct […]

If your network architecture is complex, and you’d like to quickly identify application connectivity issues due to infrastructure changes, then the new Amazon Virtual Private Cloud (VPC) Reachability Analyzer can help. Often times, it is not always clear if changes to VPC infrastructure are affecting connectivity to applications and other AWS services. By implementing automated […]

Introduction: Network Load Balancers (NLB) is the flagship Layer 4 load balancer for AWS, offering elastic capacity, high performance, and integration with AWS services like AWS Auto Scaling. NLB is designed to handle millions of requests per second while maintaining ultra-low latency, improving both availability and scalability. Network Load Balancers are widely used by all […]

This is because Route 53 health checkers are public and they can only monitor hosts with IP addresses that are publicly routable on the internet. You may want to monitor your resources […]

As of today, Application Load Balancers (ALBs) now support AWS Lambda functions as targets. Build websites and web applications as serverless code, using AWS Lambda to manage and run your functions, and then configure an ALB to provide a simple HTTP/S frontend for requests coming from web browsers and clients. Triggering a Lambda Function from […]

Introduction The Elastic Load Balancing (ELB) service provides you with Amazon CloudWatch metrics (HealthyHostCount and UnhealthyHostCount) to monitor the targets behind your load balancers. Although the unhealthy host count metric gives the aggregate number of failed hosts, there is a common pain point when you create an alarm for unhealthy hosts based on these metrics. […]
