Keep your AWS resources when you rename an AWS CloudFormation stack

Learn how to change the name of a CloudFormation stack without deleting the resources that it manages. In the walkthrough, which uses a simple architecture with a single resource, a virtual private cloud (VPC), you add a Retain attribute to the resource’s deletion policy so that the resource isn’t lost when that stack is deleted.

Save time and reduce errors by automating AWS Lambda code updates

Learn a simpler, faster method for updating your Lambda code that doesn’t require manual updates to HAQM S3. We provide a fully configured AWS CloudFormation template with Lambda code on AWS CodeCommit.

Create a more secure LAMP stack with AWS WAF (web application firewall)

Learn how to create a more secure LAMP stack with AWS WAF, Route 53 domain, and AWS Certificate Manager. This post walks you through automation steps to deploy a highly available LAMP-stack application with a web application firewall.

Reduce log-storage costs by automating retention settings in HAQM CloudWatch

Learn how to reduce log-storage costs by automating retention settings in HAQM CloudWatch. By default, CloudWatch Logs stores log data indefinitely, which is helpful. But as AWS workload logging grows, so do your log-storage costs. To reduce costs, establish a log-retention policy and apply it across all your log groups, ideally automatically.

Disaster recovery: 3 failover scenarios for your HAQM Aurora global database with Terraform (Part 2)

Simulate recovering an HAQM Aurora global database after a disaster. Walk through three failover scenarios, observe their effect on Terraform state, and learn how to maintain the global database topology and configuration using Terraform.

Collect custom metrics with HAQM CloudWatch strategic tagging

Learn how to use an HAQM CloudWatch agent to automate the collection of custom metrics for two HAQM EC2 instances. The solution is based on a tagging strategy combined with AWS Systems Manager State Manager to enforce specific CloudWatch agent configurations for EC2 instances that are tagged appropriately.

Deploy bastion hosts into private subnets with AWS CDK

Learn how to use AWS CDK to deploy bastion hosts into private subnets of a VPC.

Prepare for faster disaster recovery: Deploy an HAQM Aurora global database with Terraform (Part 1)

Learn how to automate the deployment and management of an HAQM Aurora global database—across multiple AWS Regions—with Terraform. This architecture can provide disaster recovery from Region-wide outages with low recovery time objective (RTO) and recovery point objective (RPO).

Emulate your test environment using a service virtualization on AWS

Learn how to create a service virtualization using AWS CloudFormation and HAQM API Gateway to test an application that uses an external API that’s not always available.
