Cluster Placement Group for Low-Latency Cloud Resource Colocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As availability domains (ADs) grow in size, cloud services providers face challenges in maintaining low latency for latency-sensitive workloads, as it becomes difficult to secure new data center space and power within the existing latency threshold.
Innovation Solution
The implementation of a cluster placement group (CPG) framework, which allows for the colocation of resources such as compute instances, block volumes, and database instances within the same availability domain, ensuring they share the same physical network boundary and reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If availability domains are expanded in size to accommodate more resources, then resource capacity increases, but network latency increases beyond the threshold
Solution Approach 1:
The patent segments the availability domain by introducing a cluster placement group that creates a isolated, tightly-knit subset of resources within the AD. This segmentation allows the overall AD to grow in capacity while maintaining a separate, low-latency communication path within the CPG boundary, effectively resolving the contradiction between expanded resource capacity and maintained low latency.
2Quantity of substance
If new data center space is secured to grow the availability domain, then resource capacity increases, but physical distance from existing resources increases
Solution Approach 1:
The patent merges multiple resource types (compute instances, block volumes, database instances, network resources) into a single cluster placement group that shares a common physical network boundary. This merging allows resources to be collocated in close physical proximity, enabling resource capacity expansion without increasing physical distance, as all CPG resources communicate within the same network boundary.
3Loss of time
If resources are colocated within the same availability domain, then network latency decreases, but resource allocation flexibility decreases
Solution Approach 1:
The cluster placement group serves multiple functions simultaneously: it provides low-latency networking for ultra-sensitive workloads, supports diverse resource types (compute, storage, database, network), and maintains integration with the broader cloud infrastructure. This multi-functionality allows the CPG to achieve low latency while preserving resource allocation flexibility through standardized APIs and support for various workload types.

AI summary
Described herein is a mechanism of constructing a cluster placement group in a cloud environment. A request is received from a first customer of a cloud environment, where the request corresponds to creating a cluster placement group (CPG). The CPG identifies a first set of requested resources comprising a first type of resource and a second type of resource requested by the first customer, wherein the first type of resource is different than the second type of resource. An availability domain is identified in the cloud environment that includes a second set of available resources comprising all resources included in the first set of requested resources. From the second set of available resources in the availability domain, a set of resources corresponding to the first set of requested resources to the first customer are allocated. The set of resources allocated to the first customer is associated with the CPG.
