Overview Amazon EC2 Spot Instances are a cornerstone of effective cloud cost management, offering substantial savings over On-Demand pricing. However, this benefit comes with the inherent risk of instance termination when AWS needs the capacity back. Traditionally, teams relied on a two-minute interruption notice, forcing a reactive scramble to replace lost capacity. This approach often […]

Overview In AWS, resource quotas are essential guardrails that prevent accidental overspending and ensure service stability. Among these, the Elastic IP (EIP) address limit is often overlooked until it causes a critical failure. By default, AWS sets a soft limit of five EIPs per region for each account. This constraint exists due to the global […]

Overview A core principle of cloud security and cost governance is minimizing the attack surface of your infrastructure. One of the most critical and common misconfigurations in Amazon Web Services (AWS) is assigning public IP addresses to backend EC2 instances or placing them in public subnets. These instances, which handle sensitive tasks like database operations, […]

Overview In the AWS cloud, identity is the new security perimeter. How your compute resources authenticate and gain permissions to interact with other services is a critical control point. A foundational security best practice is to use AWS Identity and and Access Management (IAM) roles for Amazon Elastic Compute Cloud (EC2) instances, moving away from […]

Overview In traditional data centers, long server uptime was a badge of honor—a sign of stability. In the AWS cloud, the opposite is true. An Amazon EC2 instance that has been running for months without a restart is often a significant security and operational liability. The longer an instance runs, the more likely it is […]
