A Container Placement Strategy Within Containerized Data Centers

What is it about?

Instantiated containers of an application are distributed across multiple Physical Machines (PMs) to achieve high parallel performance. Container placement plays a vital role in network traffic and the performance of containerized data centers. Existing container placement techniques are inadequate due to the ignorance of container traffic patterns.

Why is it important?

we first investigate the network traffic between containers and observe that it exhibits a Zipf-like distribution. Motivated by this finding, we propose a novel container placement approach- Blender -by taking into account the Zipf-like distribution. Blender employs two algorithms called RefineAlg and SplitAlg to divide containers of applications into blocks, and place these blocks across Virtual Machines (VMs). Blender exhibits two salient features: (i) it minimizes inter-block traffic by arranging the containers that communicate frequently in the same block. (ii) it achieves good load balancing by combining complementary blocks that request different resource types (e.g., CPU-intensive and memory-intensive blocks) and distributing these blocks across multiple VMs.
