#Terraform Workspaces Mastered environment isolation and automation. Managed different environments from one codebase. Used lookup() with terraform.workspace to auto-switch instance types. Single commands to swap environments. TIY: github.com/arjunthakur007…

#Terraform + #HashiCorp Vault Integrated Vault to eliminate hardcoded secrets. Zero-Trust: Secrets fetched at runtime via Vault Provider. Dynamic Credentials: Short-lived, on-the-fly access. Security: No plain-text passwords in state or code. TIY: github.com/arjunthakur007…

#Terraform Day 3: Secure Terraform Backends main.tf: Provisioned EC2, S3, & DynamoDB. S3 Backend: Secured sensitive state data remotely. DynamoDB Locking: Prevented updates & state corruption. TIY: github.com/arjunthakur007… #AWS #DevOps #CloudSecurity

#Terraform day-2: Variables: Environment separation via .tfvars and -var-file. Resources: Used Terraform Registry for official skeletons. Logic: Implemented dynamic functions and conditional logic. Structure: Modularized code by separating logic from main.tf.

Day 1 of #Terraform: Mastering IaC Automating #AWS with HCL. Milestones: Setup: Installed Terraform & AWS Provider. Workflow: Mastered init, plan, and apply. Lab: Provisioned an EC2 via main.tf. State: Learned how Terraform tracks infrastructure. #DevOps

AWS CodeCatalyst Uses: Rapid project setup via blueprints. On-demand cloud dev environments. Built-in CI/CD for automated deployments. TIY: github.com/arjunthakur007… #AWS #CodeCatalyst #DevOps #CICD #Cloud #Automation

#AWS with #Bash ! Just built a Shell Script to audit AWS services from the CLI. It Validates CLI config & args before running. Replaces manual console hunting with one command. Dynamic resource listing using Switch/Case. TIY: gist.github.com/iam-veeramalla… #DevOps #Cloud

Deployment Complete: Infra: Bootstrapped the cluster via eksctl. Auth: Configured IAM OIDC provider. Storage: Enabled EBS CSI Driver for database volumes. Networking: Integrated #AWS Load Balancer (ALB) Controller. Deploy: Used Helm Charts for the Frontend, Backend, and DB.

Today, I will try to deploy an E-commerce three tier application on #AWS EKS. Wish me luck! 😊

@r0ktech I don't even hope, let it go to the muscle memory 😑

do you take notes… or just code and hope you remember ?

#AWS Config: What it does: Continuously monitors and records our AWS resource configurations. Compliant: Resources meeting our security. Non-Compliant: Instant alerts when something drifts out of policy. #CloudSecurity #AWSConfig #DevOps #Governance

Wrote some #terraform files and made a Public VPC & an S3 Bucket. The Workflow: terraform validate - Clean syntax check. terraform plan - Previewing the infra changes. terraform apply - Provisioning live resources! TIY: github.com/arjunthakur007… #AWS #DevOps #CloudComputing

Secrets Management: #AWS SSM/Secrets Manager: Best for 100% AWS setups. Zero maintenance + native RDS rotation. #HashiCorp Vault: Best for Multi-cloud/Hybrid. Platform agnostic + dynamic secrets. Verdict: Go native for AWS speed; go Vault for multi-cloud control. #DevOps

Deployed my first website on Amazon EKS! I Set up a live project using #Kubernetes and #AWS Fargate. The Process: Provisioned cluster via eksctl. Serverless compute with Fargate (no EC2 management!). Site hosted and scaled via kubectl. TIY: github.com/arjunthakur007…

ECS vs EKS ECS: Simple: AWS-native & easy to manage. Seamless: Native IAM & ALB integration. Best For: Teams wanting speed over complexity. EKS: Flexible: Open-source K8s (no lock-in). Powerful: High scale & deep customizability. Best For: Large microservices or K8s experts.

#AWS #CloudFront : It has Low Latency: 600+ edge locations—closer to the users. Cost Savings: Caching reduces hits on the server and lowers data transfer fees. Secure S3: Use Origin Access Control (OAC) to keeping the database private while serving via HTTPS. #DevOps

#AWS Lambda lets you run code without managing servers—scaling automatically while you only pay for what you use. But to keep it truly cost-effective, you need a strategy! TIY: github.com/arjunthakur007… #AWSLambda #Serverless #CloudComputing #FinOps #DevOps #TechTips

AWS CloudWatch #CloudWatch is essential for managing #AWS services: Metrics: Real-time tracking of CPU, Disk, and Network health. Logs: Centralized logging for fast troubleshooting across EC2 & Lambda. Alarms: Set thresholds to auto-scale or notify before issues occurs.

#AWS CodeBuild: The Pros: Fully Managed: No servers to patch or manage. Deep Integration: Works seamlessly with S3, IAM, and CodePipeline. The Cons: Startup Latency: Provisioning new containers can cause delays. Complexity: Debugging buildspec.yml locally can be tricky.
