BCS instance selection guide as of September 2023
The following instance overview was written based on information available in September 2023. For the latest instance types and attributes of KakaoCloud Beyond Compute Service, see Specifications by instance type.
Hello, in this post we introduce the instances provided by KakaoCloud Beyond Compute Service (BCS).
An instance is composed of a combination of CPU, memory, storage, and networking capacity, and cloud service providers (CSPs) provide a wide range of instance choices based on users' business requirements, budgets, and constraints.
BCS is KakaoCloud's compute service and provides instance types optimized for a variety of usage environments. KakaoCloud BCS instances are broadly classified into five types.
- General-purpose instances are suitable for diverse workloads such as general web servers, databases, and application servers.
- Compute-optimized instances are suitable for compute-intensive workloads.
- Memory-optimized instances are recommended for workloads that require large amounts of memory-intensive data.
- Accelerated computing instances are high-performance computing services that use hardware such as GPUs and NPUs.
The following table compares BCS instance attributes at a glance as of September 2023.
