description AWS EC2 (t3.micro) Overview
The AWS t3.micro EC2 instance provides consistently reliable and predictable performance for small to medium workloads. It's a cost-effective option for development, testing, and low-traffic websites. While not designed for high-performance applications, its consistent resource allocation ensures stable operation. It's limited in resources and not suitable for demanding applications.

balance AWS EC2 (t3.micro) Pros & Cons
- Cost-effective option with affordable hourly rates suitable for development and testing environments
- Burstable CPU performance with CPU credits mechanism allows handling temporary workload spikes
- Included in AWS Free Tier offering 750 hours per month for the first 12 months
- Predictable and consistent baseline performance for small to medium workloads
- Easy integration with AWS ecosystem including VPC, CloudWatch, and Auto Scaling
- Supports T2/T3 Unlimited mode for sustained high CPU utilization without credits
- Limited to only 2 vCPUs and 1 GiB RAM which restricts multitasking capability
- CPU credits can deplete quickly during sustained high-CPU workloads causing throttling
- No local instance storage available; relies entirely on EBS volumes
- Network performance capped at low to moderate levels affecting data transfer speeds
- Not suitable for production high-traffic websites or compute-intensive applications
help AWS EC2 (t3.micro) FAQ
What are the CPU credits and how do they work on t3.micro instances?
T3.micro earns 12 CPU credits per hour that can be used to burst above the 10% baseline performance. When your workload needs more CPU, it consumes credits. If credits run out, performance drops to baseline until you earn more.
How many hours of t3.micro usage is included in AWS Free Tier?
AWS Free Tier includes 750 hours per month of t3.micro usage for the first 12 months after account creation. This covers running one instance continuously or multiple instances part-time.
Can t3.micro handle a production website with moderate traffic?
A t3.micro can support low-traffic production websites but struggles with moderate traffic spikes due to limited RAM and CPU credits. For business-critical sites, consider t3.small or larger instances.
What is the difference between t2.micro and t3.micro?
T3.micro offers 2 vCPUs versus t2.micro's 1 vCPU, 33% more CPU credits per hour (12 vs 9), newer Xeon processors, and better price-to-performance ratio overall.
Does t3.micro support T3 Unlimited mode?
Yes, t3.micro supports T3 Unlimited which allows sustained CPU usage above baseline by charging additional fees when credits are insufficient. This is useful for unpredictable workloads.
