m8in.4xlarge

The m8in.4xlarge is a general-purpose AWS EC2 instance: 16 vCPU and 64 GiB of memory, 4.00 GiB per vCPU. In the name, "m" is the general-purpose line, "8" is the generation, "in" marks Intel processors and enhanced networking and "4xlarge" is the size within the m8in family. It runs on Intel Xeon Scalable (Granite Rapids) at 3.9 GHz, and AWS introduced it in April 2026. AWS has since shipped m9g; m9g.4xlarge is the direct replacement at this size, scoring 575,195 CoreMark/s against this instance's 371,632 — roughly 55% more throughput for the same vCPU count. Rackspace Spot's gp.vs2.2xlarge is a like-for-like substitute at 16 vCPU and 64 GiB, $1.34/hr on AWS in US East (N. Virginia), from $0.041/hr on Rackspace Spot.

When to use it

Good for

●Small to mid-size relational databases
●Backend services with no single dominant resource
●Queue workers and scheduled jobs
●Workloads that fit inside 64 GiB of RAM
●Parallel work that can occupy 16 vCPU
●Network-heavy services — AWS rates this size at Up to 50 Gigabit

Avoid if

●The working set needs more than 64 GiB of RAM
●More than 4.00 GiB of RAM per vCPU is needed — that ratio is fixed for the whole family
●The work is single-threaded. Most of these 16 vCPU would sit idle.
●Local NVMe or instance-store disk is a hard requirement
●GPU or FPGA acceleration is needed
●Sustained full-core CPU load. A compute-optimized family costs less per unit of work.

Stop overpaying AWS. This compute costs $976/mo on AWS vs $30/mo on Rackspace Spot.

Spot sells spare capacity at market prices. It is the cheapest compute on the internet.
Prices are set by supply and demand. You pay what the market decides.
Compute is delivered as fully managed Kubernetes. All infrastructure is taken care of.
Egress costs $0.01/GB after the free allowance. AWS charges $0.09/GB.
