A well-designed network architecture is the backbone of any cloud infrastructure. It ensures better performance, security, resilience, and easier troubleshooting. Additionally, choosing the right networking solutions can optimize costs by leveraging AWS services that align with your application’s needs. This article focuses on complex, large-scale setups where multiple teams operate across multiple AWS accounts and regions. Let’s dive into AWS’s networking offerings and explore the best options for connecting Virtual Private Clouds (VPCs) and external networks. This guide compares VPC Sharing, VPC Peering, AWS Transit Gateway (TGW), and AWS Cloud WAN, highlighting their use cases, advantages, and limitations. ...

Introduction Pre-commit is a framework for managing and enforcing Git pre-commit hooks. It helps automating code quality checks before committing changes, ensuring that issues like formatting, linting, and security vulnerabilities are caught early. Essentially, pre-commit runs a range of checks automatically before each Git commit. Not only does it highlight issues, but it can also fix them before they even make it into your repository. ...

I’ve just earned all three AI/ML AWS certifications and want to share my subjective thoughts about each certificate in particular. Inspiration I decided to pursue these three AWS AI/ML certifications after attending re:Invent 2024 in Las Vegas. Nearly every talk revolved around AI - how to integrate AI into workloads or how AI is already transforming solutions both within and beyond AWS. ...

Introduction Topology Aware Routing (TAR) is a Kubernetes feature designed to keep traffic within the same availability zone (AZ). This can reduce cross-AZ traffic costs on cloud providers like AWS and GCP, where inter-AZ traffic incurs charges. Additionally, it can lower latency by keeping network requests local. However, TAR is not a silver bullet. While it helps optimize costs and performance, it strictly prohibits cross-zone traffic, regardless of the system’s health or workload distribution. This limitation can lead to unintended service disruptions. ...

Public IP Address You can always use your own nginx instead of using 3rd party services when you need to know your public IP. Like this: # Public IP location = /ip { default_type text/plain; return 200 $remote_addr; } Or if you need it in JSON format like this: # Public IP JSON location = /ip_json { default_type application/json; return 200 "{\"ip\":\"$remote_addr\"}"; }
