AWS CloudFormation-Beginner to Advanced (Hands-On with YAML)

Explore the resource section of a CloudFormation template, learning how to declare resources like an S3 bucket, an EC2 instance, and a VPC with logical ID and properties in us-east-1.

Learn to create an S3 bucket resource in a yaml CloudFormation template by outlining template format version, description, and resources, then deploy the stack in us-east-1 and verify creation.

Create an s3 bucket and an ec2 instance with cloud formation in yaml, detailing template structure, resources, logical and physical ids, and region-specific image selection.

Learn to create a VPC with CloudFormation by editing a template, setting CIDR 10.0.0.0/16, enabling DNS hostname and DNS support, and tagging the resource, then deploy in us-east.

Explore how parameter blocks let you customize a cloud formation template at runtime with values like instance type or image ID, using defaults, allowed values, and descriptions.

Parameterize a CloudFormation template by adding a parameters section for image id, instance type, and bucket name, using Ref and defaults to pass values at runtime.

Add metadata to a CloudFormation template and organize parameters into compute and storage groups with labels, featuring EC2 instance type and S3 bucket name, in a hands-on walkthrough.

Explore CloudFormation template anatomy by constructing a stack in us-east with a VPC, a public subnet, an EC2 instance, and an S3 bucket, wired together with resources, parameters, and metadata.

Build a serverless banking use case using AWS API Gateway, Lambda, and S3. See how an API call retrieves a balance from a JSON object in S3 via Lambda.

Learn to create a uniquely named S3 bucket with CloudFormation, configure it in a serverless yaml template, and deploy the stack for a bank balance app.

Create a lambda execution role in CloudFormation by defining an assume role policy and attaching an S3 full access policy to the Lambda, enabling S3 data access.

Create an AWS Lambda function via CloudFormation YAML, using Python 3.9 and an IAM role to read a JSON object from S3 and deliver it to API Gateway.

Build and deploy a rest api with aws api gateway using cloudformation, adding a balance status resource and a get method, then deploy in a subsequent step.

Build an API gateway method in CloudFormation, connect a non-proxy AWS Lambda integration, configure integration and method responses, deploy to prod, and set permissions for API gateway to invoke Lambda.

Demonstrate an end-to-end serverless banking rest API built with AWS CloudFormation, testing a get method that retrieves data from S3 via a lambda function, deployed to prod with invoke URL.

Parameterize key inputs in the CloudFormation template, such as the S3 bucket name and Lambda runtime. Describe parameters, set allowed values, and reference them in resources to enable serverless deployment.

Build a metadata interface in a CloudFormation template by grouping S3 bucket, Lambda, and API gateway with labeled parameters, then upload the template and complete the stack deployment.

Set up a two-instance auto scaling group behind an application load balancer, configure Route 53 with a hosted zone, and enable CloudWatch logs, alarms, and notifications.

Build an application load balancer with a listener and target group, connect it to the auto scaling group, and test round-robin routing through the load balancer DNS.

Create an AWS CloudWatch log group and an SNS topic with an email subscription as part of the CloudFormation workflow, enabling Route 53 host zone setup for the web application.

Create a public hosted zone and Route 53 records to map an ALB hostname to a domain, using CloudFormation and a sub function for dynamic log configuration.

Create a CloudWatch alarm in CloudFormation YAML that monitors an auto scaling group's CPU utilization, triggers actions via an SNS topic, and emails admins on threshold breaches.

Demonstrates end-to-end deployment with a CloudFormation yaml template, creating a web server launch configuration, auto scaling group, and an application load balancer. Monitors with CloudWatch alarms, logs, and SNS notifications.

Master practical cloud troubleshooting for AWS CloudFormation deployments by diagnosing security group and subnet routing issues, enabling proper inbound and outbound traffic, and ensuring internet gateway routes are configured.

Deploy CloudFormation templates via AWS CI-CD pipeline without parameters, using CodePipeline and a YAML template to create or update a stack that provisions an S3 bucket.

Parameterize cloud formation templates and deploy via a cd pipeline with a separate json parameters file. Build a wrapper, upload files, and configure the pipeline to create or update stack.

Explore change sets in AWS CloudFormation to preview proposed template changes. Learn to create, view, adjust, and execute changes, including no interruption, some interruption, or full replacement.

Learn to create and review change sets in CloudFormation, compare current and new templates, modify parameters like instance type and S3 bucket, and execute or replace updates while noting interruptions.

Explore how cloudformation uses an IAM service role to perform stack operations and how to assign a dedicated role with permissions for EC2 and S3.

Explore how CloudFormation deletion policies retain resources like an S3 bucket when deleting a stack, by applying a retention policy and observing the deletion behavior.
