@cloudandtechie Needs to be scalable, fault-tolerant

@clovisdsdo S3 is the storage service, while an s3 bucket is a container inside S3 where you actually store your objects

@Taniyatweets_ Linux - I’d choose control and flexibility over convenience

@Taniyatweets_ Coding

[Janhavi Jagtap @JanhaviTechAWS]

@chanduuu_cs accuracy is the most important factor, after that we prioritize speed.

[Janhavi Jagtap @JanhaviTechAWS]

@neerajjj6785 Nooo..,.

@clovisdsdo You can’t directly move an ec2 instance to another subnet. I’d create an AMI of the existing instance, launch a new instance from that AMI in the correct subnet, test it, and then terminate the old instance.

🚨Day 28/30 - AWS Disaster Recovery

Production systems need a plan for failures.

Backup ≠ DR

Backup → Recover data
DR → Recover the entire service

RPO + RTO + Failover + Testing = Reliable DR

@uday_devops Cloud trail

[Janhavi Jagtap @JanhaviTechAWS]

High Availability ≠ simply adding more servers.

A production system needs redundancy + health checks + monitoring + automated recovery + tested failover.

Secret tip- If failover has never been tested, you don't really know whether your HA design works.

🚀Day 27/30 - High Availability & Scalability

Production architecture-
Route 53→ALB →EC2/EKS →DB
✅Multi-AZ
✅Auto Scaling
✅Health Checks
✅No Single Point of Failure

Goal:Reliable systems that stay available even when components fail.

@prayag_sonar OpenCode said "bring it on" to the whole industry😅

[Janhavi Jagtap @JanhaviTechAWS]

@BytePilotLabs True, I'd also add checking is step 1, but actually testing failure (chaos engineering/ manual failure injection) confirms if redundancy really works or just looks good on paper

@Rabay_Hasan AWS

[Janhavi Jagtap @JanhaviTechAWS]

@PratikSinhatwt No, Practical experience matters, especially understanding how the system actually works

[Janhavi Jagtap @JanhaviTechAWS]

@willie_sre Never assume a deployment is safe just because the pipeline is green. Production has a way of finding the edge cases your tests missed😂

[Janhavi Jagtap @JanhaviTechAWS]

@the_codewala it’s a data-interchange format used to store and transfer structured data...

[Janhavi Jagtap @JanhaviTechAWS]

@kritikakodes Maybe the vibe ends where kubectl apply begins..😂

@ydamitcodes Security

@clovisdsdo Bcz the NAT Gateway needs a route to the Internet Gateway. So it is placed in a public subnet, while private subnet resources route their outbound internet traffic through the NAT Gateway.
