Here's What It Leaves on the Table." Justin was a developer advocate on the Karpenter product team, validating customer use cases and helping shape the design. So this isn't an outsider's take on what Karpenter can't do - it's someone who was in the room explaining where node autoscaling was always meant to stop, and what has to sit above it. Karpenter is very good at what it does. Keep running it. The panel is about the gap that stays open anyway: - why well-tuned Karpenter clusters still sit around 10% CPU utilization - why consolidation gets switched off - and how container live migration makes it safe for stateful workloads - how Spot interruption prediction changes the math in production - same layer, same logic on Karpenter and standard cluster autoscaler - nothing to rip out One hour, free, open Q&A. Bring your hardest Karpenter question. 📅 September 17, 2026 ⏰ 4:00 - 5:00 PM PST 📍 Online (https://d2nJ7W04.na1.hubspotlinks.com/Ctc/OR+113/d2nJ7W04/VX2yXv6VyDXLW27L3Jd3dHqlHW3_3yVc5V0FckN5j5FRq3pyd0W95jsWP6lZ3pXW9grSCK73mMVNW6dpS_z6chDXBN29wc_P2StZ8W2G1dj92nYd8CW4SytmB4MVQcBN2RY7l6TxQf6W1YR7Kz2l4QWRW7VW3xH7FlFDFW10VJZT8xQbw-VK2dN5267SkzW1PSQfP88B7d3W6TtYpZ5B3B91W43xlgj4hRDcTW7c9g7l8LHdyTW7SRfRD5P2trfW259b8L1knkZgW6PR2kJ2N2gM_W6vZlRB520NGhW6lL-5y4D3XnnW4kxXXQ4-qsdVW6Hs6Qf55ZJ9DVC5w923yPLC1W5fz4sg5kr74KW5z6w1g84hgYHW6HG5Gn6Hk9DLW4NWlKP1BXrmwW5rJNr15VlfPZW5JbJRt6RH0YnVYHJYx6hM0XVW1c8lmd25NYDjf6pgFld04 ) Register now (https://d2nJ7W04.na1.hubspotlinks.com/Ctc/OR+113/d2nJ7W04/VX2yXv6VyDXLW27L3Jd3dHqlHW3_3yVc5V0FckN5j5FRq3pyd0W95jsWP6lZ3pXW9grSCK73mMVNW6dpS_z6chDXBN29wc_P2StZ8W2G1dj92nYd8CW4SytmB4MVQcBN2RY7l6TxQf6W1YR7Kz2l4QWRW7VW3xH7FlFDFW10VJZT8xQbw-VK2dN5267SkzW1PSQfP88B7d3W6TtYpZ5B3B91W43xlgj4hRDcTW7c9g7l8LHdyTW7SRfRD5P2trfW259b8L1knkZgW6PR2kJ2N2gM_W6vZlRB520NGhW6lL-5y4D3XnnW4kxXXQ4-qsdVW6Hs6Qf55ZJ9DVC5w923yPLC1W5fz4sg5kr74KW5z6w1g84hgYHW6HG5Gn6Hk9DLW4NWlKP1BXrmwW5rJNr15VlfPZW5JbJRt6RH0YnVYHJYx6hM0XVW1c8lmd25NYDjf6pgFld04 ) Can't make it live?
