I also learned about snapshots a point-in-time backups that are a lifesaver for disaster recovery.

Why does this matter? Misconfigured S3 buckets are one of the most common breaches. Understanding storage security is essential for protecting what matters most. 🔐

Block storage is like a raw hard drive, fast and perfect for databases. File storage works like a shared network drive for collaborative workloads. Object storage like S3 is built for massive scalability, perfect for images, videos, and backups.

#AWS #S3 #Storage

[Oresanya khaleed Walcott @cyberwalcott]

My AWS journey just hit storage and there is so much more to it than I expected. 📦

I explored the three main types of cloud storage and how they serve different purposes.

The most valuable part? Understanding security at every layer.

Network ACLs act as firewalls at the subnet level, while security groups protect individual resources.

Misconfigured networks are a top entry point for attackers. I'm learning to spot them before they become breach

[Oresanya khaleed Walcott @cyberwalcott]

Inside the VPC, I learned about subnets for organizing resources, internet gateways for public access, and virtual private gateways for connecting back to on-premises data centers.

It's like building your own secure data center in the cloud. 🔐

#CloudSecurity #AWS #Networking

[Oresanya khaleed Walcott @cyberwalcott]

My AWS journey just hit the networking layer—and this is where cloud security really comes alive. 🌐

I explored Amazon VPC, which is essentially your private network in the cloud.

#AWS #VPC #CloudComputing #Networkin

[Oresanya khaleed Walcott @cyberwalcott]

Infrastructure as Code means deploying cloud environments consistently across Availability Zones with code eliminating human error and making security auditable.

Kubernetes adds portability running containers across AWS, Azure, or anywhere.

This is how you build secure🔐☁️

[Oresanya khaleed Walcott @cyberwalcott]

Understanding containers and Kubernetes has been a game-changer. Packaging applications to run consistently anywhere? Orchestrating them seamlessly across different cloud platforms? That's the power of cloud-native architecture.

he learning curve is steep—but worth every minute

[Oresanya khaleed Walcott @cyberwalcott]

My AWS Cloud Practitioner journey just leveled up! 🚀 I'm diving deep into the tools that power modern cloud native applications—containers, Kubernetes, and Infrastructure as Code.

You can't secure what you don't understand. Time to go beyond the basics.

[Oresanya khaleed Walcott @cyberwalcott]

@gabbytech01 congratulation sir

[Oresanya khaleed Walcott @cyberwalcott]

Just wrapped up the AWS Intro and EC2 (loved playing with virtual servers & security groups).Now I'm currently neck-deep in AWS Lambda—and honestly, serverless computing is blowing my mind! 🤯Running code without managing servers? That's the future right there.#Cloudcomputing

[Oresanya khaleed Walcott @cyberwalcott]

🚀 Cloud learning is in full swing !

My personal rule: You can't secure what you don't understand. So I'm diving deep into AWS to understand cloud infrastructure from the ground up.

Securing the cloud starts with knowing how it works. ☁️🔐

[Oresanya khaleed Walcott @cyberwalcott]

4 months ago I knew nothing about cybersecurity.
I completed TechCrush Bootcamp with 88.8% 🎉

Thank God for the journey.

This is just the beginning.
Next stop: Cloud Security.

#CybersecurityStudent #TechCrush #CloudSecurity

[Oresanya khaleed Walcott @cyberwalcott]

Just finished my cybersecurity fundamentals.

Now I’m going all-in on AWS Cloud Security + IAM.

Learning in public and documenting everything.
