This happens when traffic crosses zone boundaries twice, triggering charges at every hop and significantly increasing your total monthly infrastructure spend." } }, { "@type": "Question", "name": "What monthly savings occur by enabling zonal affinity on a busy EKS cluster?", "acceptedAnswer": { "@type": "Answer", "text": "Implementing zonal affinity reduces monthly expenses from $204.80 down to $10.24 for large clusters. This specific configuration change confines traffic within single zones, eliminating the redundant charges inherent in standard cross-zone replication patterns." } }, { "@type": "Question", "name": "What DNS affinity setting eliminates cross-AZ charges for internal NLB operations?", "acceptedAnswer": { "@type": "Answer", "text": "Shifting the DNS record client routing policy from 0% to 100% forces local resolution. This setting ensures clients connect only to load balancers in their own zone, preventing expensive inter-zone data transfer levies from accumulating." } }, { "@type": "Question", "name": "How much inter-AZ traffic does an unoptimized EKS cluster with 50 services generate?", "acceptedAnswer": { "@type": "Answer", "text": "An unoptimized EKS cluster with 50 services generates 5 TB to 10 TB of monthly inter-AZ traffic. These unoptimized flows across three availability zones trigger double-billing events at every single zone boundary encountered." } }, { "@type": "Question", "name": "What is the base charge per direction for traffic crossing Availability Zone borders?", "acceptedAnswer": { "@type": "Answer", "text": "Cross-AZ traffic triggers a $0.01 levy at both the ingress and egress points of every zone. This symmetric billing model means a single request-response cycle between different zones incurs a total $0.02 charge." } } ] } </script> <!-- /wp:html --> <!-- wp:html --> <style> .faq-section { margin: 24px 0; padding: 24px 0; border-top: 2px solid #e5e7eb; } .faq-section-title { color: #1a1a1a; font-size: clamp(1.2rem, 3vw, 1.4rem); font-weight: 700; margin-bottom: 24px; text-align: center; } .faq-item { background: #fff; border: 1px solid #e5e7eb; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: all 0.3s ease; } .faq-item:hover { border-color: #2563eb; box-shadow: 0 4px 6px rgba(0,0,0,0.05); transform: translateY(-2px); } .faq-question { background: #f9fafb; padding: 12px 16px; cursor: pointer; position: relative; transition: all 0.3s ease; border: none; width: 100%; text-align: left; font-family: inherit; display: block; } .faq-question:hover { background: #e8f0fe; } .faq-question-text { color: #1a1a1a; font-size: 1rem; font-weight: 600; line-height: 1.5; margin: 0; padding-right: 2rem; display: inline-block; } .faq-answer { max-height: 0; overflow: hidden; transition: max-height 0.4s ease, padding 0.4s ease; padding: 0 16px; } .faq-item.active .faq-answer { max-height: 1000px; padding: 0 16px 16px; } .faq-answer-text { color: #4b5563; font-size: 1rem; line-height: 1.7; margin: 12px 0 0; } </style> <script> (function() { function initFAQ() { var qs = document.querySelectorAll(".faq-question"); for (var i = 0; i < qs.length; i++) { qs[i].addEventListener("click", function() { var item = this.closest(".faq-item"); var wasActive = item.classList.contains("active"); var allItems = document.querySelectorAll(".faq-item"); for (var j = 0; j < allItems.length; j++) { allItems[j].classList.remove("active"); } if (!wasActive) item.classList.add("active"); this.setAttribute("aria-expanded", String(!wasActive)); }); } } if (document.readyState === "loading") { document.addEventListener("DOMContentLoaded", initFAQ); } else { initFAQ(); } })(); </script> <!-- /wp:html --> <!-- wp:paragraph {"className":"std-text"} --> <!-- /wp:paragraph --> <!-- wp:paragraph {"className":"std-text"} --> <p class="std-text">Double-crossing Availability Zones with an <strong>AWS Network Load Balancer</strong> instantly doubles your transfer bill to <strong>$0.04 per GB</strong>.</p>
