AWS Lambda Explained in Simple Terms.
Introduction. AWS Lambda is a serverless computing service provided by Amazon Web Services that allows developers to run code without having to manage servers, making it an ideal starting point for beginners in cloud computing. With Lambda, developers can focus on writing code while AWS automatically handles the infrastructure, including provisioning, scaling, and managing the […]
AWS Lambda Pricing Explained.
AWS Lambda pricing is a pay-as-you-go model that allows users to run code without provisioning or managing servers, charging only for the resources actually consumed during execution. The cost is primarily based on the number of requests made to a Lambda function and the amount of compute time used to process those requests. Each time […]
AWS Lambda Explained: How Serverless Computing Actually Works.
Introduction. AWS Lambda is a serverless computing service. It is provided by Amazon Web Services. AWS Lambda removes server management. Developers do not provision servers. Infrastructure is fully managed by AWS. Serverless computing runs code on demand. AWS Lambda executes code automatically. Functions are triggered by events. Events come from AWS services. API Gateway triggers […]
Comparing EC2, ECS & EKS with Use Cases.
Introduction. Choosing the right compute service on AWS is one of the most important architectural decisions a DevOps engineer can make. Amazon EC2, ECS, and EKS all provide ways to run applications in the cloud, but they solve very different problems. At first glance, these services may look similar because they all allow you to […]
Deploying an EC2 instance and connecting over SSH with PuTTY
Introduction: Launching an EC2 instance and SSH using PuTTY refers to the process of creating a virtual server (EC2 instance) in AWS and then securely connecting to it from a Windows computer using PuTTY, an SSH client. Lab Steps Step 1: Sign to the AWS Management Console 1. Click on the Open Console button, and […]
Getting started with Lambda Function
Introduction Introduction to Amazon Lambda refers to learning the basics of AWS Lambda, a serverless compute service that lets you run code without managing servers. It covers how to create Lambda functions, set triggers, manage permissions, and execute code in response to events like API calls, S3 uploads, or SQS messages. Lab Steps Step 1: […]
Deploying Kubernetes Ingress via ALB in EKS
Introduction Kubernetes Ingress with AWS Application Load Balancer (ALB) on Amazon EKS allows you to manage external access to your Kubernetes services using HTTP/HTTPS. By deploying the AWS Load Balancer Controller in your EKS cluster, Kubernetes Ingress resources automatically create and configure an ALB. This setup helps route traffic to different services based on paths […]
Introduction to Amazon Elastic Container Service (ECS)
Introduction Amazon ECS is a fully managed container orchestration service that helps you run, manage, and scale Docker containers on AWS. It removes the need to set up your own container management system by providing built-in scheduling, networking, and scaling features, so you can easily deploy containerized applications with high reliability and performance. Lab Steps […]
Create an AWS EC2 Instance and run some AWS CLI Commands.
Introduction. Creating an AWS EC2 Instance and running AWS CLI commands means launching a virtual server in AWS and then using the AWS Command Line Interface to perform basic operations such as checking resources, managing services, or testing AWS access directly from that server’s terminal. Lab Steps Step 1: Sign to the AWS Management Console 1. […]
Step-by-Step: Mount EFS on EC2.
Introduction. Amazon Elastic File System (EFS) is a scalable and fully managed network file system that allows multiple EC2 instances to access shared storage simultaneously. It is designed to provide elastic capacity, meaning it can automatically grow and shrink as you add or remove files, eliminating the need to provision storage in advance. Mounting EFS […]
