# Instance Families

> Choose the right instance family for your workload.

Lineserve Cloud Servers are available in five families with AWS-style naming. Instance sizes range from 1 to 64 vCPU and 1 to 512 GB RAM.

## Families at a glance

| Family            | Prefix | vCPU:RAM ratio | CPU type                      | Best for                            |
| ----------------- | ------ | -------------- | ----------------------------- | ----------------------------------- |
| General Purpose   | m6i.   | 1:4            | Dedicated                     | Balanced web and app workloads      |
| Compute Optimized | c6i.   | 1:2            | Dedicated                     | CPU-heavy processing and batch jobs |
| Memory Optimized  | r6i.   | 1:8            | Dedicated                     | In-memory databases and analytics   |
| Storage Optimized | i3.    | 1:4            | Dedicated                     | High I/O and large datasets         |
| Burstable         | t3.    | 1:4            | Shared cores with CPU credits | Cost-efficient, variable workloads  |

## Performance notes

* Dedicated families use Intel Xeon Gold 6240R cores and support up to 25 Gbps networking.
* Burstable instances use shared cores with baseline CPU performance and can burst to 100% using CPU credits.
* Included outbound traffic varies by size (example: m6i.small includes 1 TB).
* Storage is sized independently from compute and can be resized without changing instance type.

## When to choose what

* Choose General Purpose for most web apps and microservices.
* Choose Compute Optimized for CPU-bound workloads or high concurrency.
* Choose Memory Optimized for caching, analytics, and large databases.
* Choose Storage Optimized for heavy I/O, search, and log processing.
* Choose Burstable for dev/test or light production traffic.
