**Why This Comparison Still Matters ****In many AWS accounts we still see T2 instances running production workloads. Most of the time, this isn’t by choice. It’s usually inheritance — old templates, old AMIs, or “this is what we launched years ago”. The issue here is: you are likely paying more money for worse performance.--- ** You received: ** ** ** For the same workload: If you are running: ** ** Migrating from T2 to T3 is usually straightforward: Ensure your AMI supports Nitro-based instances Use T3 When: ** Is T3 cheaper than T2 in AWS EC2? In most real-world scenarios, T3 instances are more cost-efficient than T2. They offer improved baseline performance and flexible CPU credit usage, which helps reduce unexpected costs. What are CPU credits in T2 and T3 instances? CPU credits allow burstable instances to handle temporary spikes in usage. T2 instances have stricter credit limits, while T3 provides more flexible credit options, making it better for variable workloads. When should I choose T3 over T2? You should choose T3 when your workload requires consistent performance or occasional bursts. T3 is generally better for modern applications due to its cost-performance balance. ** How Kubernetes Routes Pod Traffic with a Single Egress IP GP3 vs GP2 EBS Volumes: Performance and Cost Comparison How to Set Up a Self-Hosted GitHub Actions Runner ** For anything new, T3 should be the default. That single decision can quietly reduce cost and eliminate an entire class of performance issues.
