x64-based virtual machines x64-based virtual machines use the 64-bit x86 instruction set architecture, widely used in desktop and server environments. They offer compatibility with various operating systems and software. x64 processors are known for their strong performance in complex calculations and multi-threading. Commonly used for general-purpose computing, web hosting, database management, and enterprise workloads. Suitable when software compatibility and high-performance computing are essential.

Arm64-based virtual machines Arm64-based virtual machines use the 64-bit ARM architecture, commonly found in mobile devices and low-power systems. They offer good performance per watt and excel in parallel processing. Arm64 VMs are suitable for IoT, edge computing, and containerized workloads. Software compatibility may be limited compared to x64. Ideal for scenarios prioritizing energy efficiency and ARM-specific optimizations. Amazon Web Services (AWS)

Choose x64-based virtual machines when:

Compatibility: You need broad OS and software support with traditional x86-64 applications.
High Performance: For complex calculations and memory-intensive workloads.
General-purpose Computing: Web hosting, databases, and various enterprise applications.
Established Ecosystem: Well-established with extensive software and tooling options.
No Energy Constraints: Energy efficiency is less critical compared to performance.

Choose Arm64-based virtual machines when:

Energy Efficiency: You prioritize power efficiency and performance per watt.
IoT and Edge: For IoT devices, edge computing, and low-power applications.
Containerized Workloads: Taking advantage of ARM-specific container optimizations.
Specific ARM Software: When applications are compiled and optimized for ARM architecture.
Future Growth: As the ARM ecosystem expands, more software support will become available.
