Security incidents in AWS rarely stem from zero-day exploits against the hypervisor. In practice, they trace back to routine configuration drift: an IAM policy wildcard added at 2 AM to fix a broken deployment, a database spun up in a public subnet for staging, or a security group rule left open to 0.0.0.0/0. AWS operates […]
Introduction This blog provides step-by-step instructions to implement AWS IAM Identity Center with Microsoft Entra ID as the identity source. Authentication is handled via SAML 2.0. User and group provisioning is handled via SCIM 2.0. IAM Identity Center is administered from a dedicated Identity account using Delegated Administration. Prerequisites AWS Organization active with All Features […]
Introduction As applications move from monoliths to microservices, every new service tends to expose its own API. That sounds fine at first—until each service also has to handle its own authentication, rate limiting, logging, and routing. The result is duplicated logic scattered across every service, and clients that need to know about every backend individually. […]
Introduction When designing cloud solutions in AWS, one has to make a choice between secure isolation and accessibility. The recommended practice is to place all application servers, databases, and internal API’s in a private subnet and deny their access to the Internet. But then, how can developers, operations engineers, and system administrators access these resources […]
Locking Down the Front Door: IAM and Access Control in AWS Most AWS breaches don’t start with a zero-day exploit. They start with an over-permissioned role, a leaked access key, or a policy that grants *:* (a wildcard meaning “every action, on every resource”) because it was faster than scoping it properly. Identity and Access […]
INTRODUCTION Have you ever woken up to a dozen AWS health notifications, each one technical, urgent, and demanding your immediate attention? Imagine it’s 2 a.m. and AWS sends a health notification: an EC2 instance is being retired in 48 hours. Ten minutes later, a second email arrives about a mandatory RDS upgrade. By morning, there […]
Introduction Running Kubernetes workloads on Amazon EKS is easy, but running them in a cost-effective way is a different challenge. Many organizations start their Amazon EKS clusters with Managed Node Groups based on Auto Scaling Groups (ASGs). This is a reliable approach but often results in over-provisioning of infrastructure as worker nodes are kept running […]
Introduction Someone asked me last week whether Cost Explorer works like Resource Explorer, just for billing. It’s a reasonable guess. Same suffix, same console, both let you slice things by region. The guess is wrong in a way that costs people real time, so it’s worth pulling apart. One is a search index. The other […]
Introduction Imagine a client’s website fails at midnight. Your team is on Slack, and raising a support ticket involves opening a browser, logging into Fresh service, filling out a form, and waiting for it to be assigned. In an urgent situation, every extra step adds unnecessary delay. so to simplify this, we created a Slack […]
