A Lambda layer is a distribution mechanism for libraries, custom runtimes, or other dependencies required in the AWS Lambda functions. Cloud engineers can manage and reuse these libraries and dependencies across multiple functions by packaging them into a layer. By the end of this note, you will learn how to create a Lambda layer for … Continue reading Create AWS Lambda Layer using Docker, Terraform and GitHub Actions
In this note, I discuss creating an Amazon RDS for PostgreSQL DB using Terraform and securely automating the provisioning process using GitHub Actions. By the end of this note, you will learn about the underlying architectural dependencies and specific properties needed to create a secure RDS for PostgreSQL DB using Terraform. Per AWS-Docs, Amazon Relational … Continue reading Create Amazon RDS for PostgreSQL DB using Terraform and GitHub Actions
This note is the second part of my notes on Amazon ElastiCache for Memcached. In the first note, I demonstrated how to create an Amazon ElastiCache for Memcached using Terraform. In this note, I list the steps to create the additional infrastructure and access the Memcached cluster using Python. To accomplish the use-case, I'll use … Continue reading Access Amazon ElastiCache for Memcached from an Amazon EC2 instance using Python
Caches store frequently accessed data in memory, which is accessible much faster than disk-based storage or even a database. This capability reduces data retrieval latency and improves the application response times. Amazon ElastiCache for Memcached is a fully managed caching service, which means AWS handles maintenance, patching, backups, and monitoring. In this note, I demonstrate … Continue reading Create Amazon ElastiCache for Memcached using Terraform and GitHub Actions
Fleet Manager is a service AWS Systems Manager provides to securely manage Amazon EC2 instances at scale. Cloud engineers can log in via remote desktop (RDP) to Amazon EC2 instances for Windows using Fleet Manager to perform troubleshooting or management tasks. Previously, a set of configurations were required to access an Amazon EC2 instance for … Continue reading Secure RDP Access to Amazon EC2 for Windows: Leveraging Fleet Manager and Session Manager
Amazon CloudWatch is a monitoring and observability service that Amazon Web Services (AWS) provides. It monitors log files, collects and tracks metrics, sets alarms, and triggers actions to help AWS users ensure the health and performance of their applications and infrastructure resources. CloudWatch integrates with various AWS services, such as Amazon EC2, to provide comprehensive … Continue reading Install and configure CloudWatch Logs agent on Amazon EC2 instance for Windows using user data
Credentials and sensitive variables allow access to confidential data and must be protected from unauthorized access so only permitted entities can access them. AWS Fargate is a technology that can be used with Amazon ECS to run containers. AWS Fargate is commonly used to run workloads to interact with databases or access confidential data or … Continue reading Protecting Credentials and Variables in AWS Fargate Containers using AWS Secrets Manager
In Amazon Elastic Container Service (ECS), HealthCheck is a mechanism for monitoring the health status of containerized applications running in tasks. It helps ensure that only healthy containers (with health check passing) serve traffic and unhealthy containers are replaced automatically. Configuring the ECS Managed Healthcheck is crucial for maintaining the availability, reliability, and scalability of … Continue reading Enabling Health Checks and CloudWatch Logs for AWS Fargate Tasks
Per AWS-Docs, AWS Lambda is a serverless computing service provided by Amazon Web Services (AWS) that allows developers to run code without provisioning or managing servers. With Lambda, you can execute code in response to events such as HTTP requests, database changes, or file uploads, scaling automatically with usage. It supports various programming languages and … Continue reading Automating AWS Lambda Deployment: Harnessing Terraform, GitHub Actions, and Python for CloudWatch Logging
This note aims to demonstrate how to deploy a couple of CloudFormation templates using GitHub Actions to create Amazon cloud resources. There are two tools we're discussing. The first one is AWS CloudFormation, an infrastructure as a code tool to provision AWS cloud resources declaratively. The AWS cloud resources and their relationships are declared in … Continue reading Automating AWS Infrastructure with CloudFormation and GitHub Actions: A Tutorial
