Measuring OpenEBS Local Volume Performance Overhead in Kubernetes

OpenEBS Local Volume Performance Overhead Kubernetes

I wrote about the usage of OpenEBS to manage local storage in Kubernetes in my previous posts:
Deploying Percona Kubernetes Operators with OpenEBS Local Storage
OpenEBS for the Management of Kubernetes Storage Volumes
The primary reason to use the local storage is performance and the logical question is then: How big is the performance overhead if we […]

OpenEBS for the Management of Kubernetes Storage Volumes

I recently wrote about OpenEBS in regard to local volumes in my post Deploying Percona Kubernetes Operators with OpenEBS Local Storage. And there are also my recent blog posts about Kubernetes, Percona Operators, and storage management problems:

ChaosMesh to Create Chaos in Kubernetes

ChaosMesh to Create Chaos in Kubernetes

In my talk on Percona Live (download the presentation), I spoke about how we can use Percona Kubernetes Operators to deploy our own Database-as-Service, based on fully OpenSource components and independent from any particular cloud provider.
Today I want to mention an important tool that I use to test our Operators: ChaosMesh, which actually is […]

Using Volume Snapshot/Clone in Kubernetes

Volume snapshot and clone Kubernetes

One of the most exciting storage-related features in Kubernetes is Volume snapshot and clone. It allows you to take a snapshot of data volume and later to clone into a new volume, which opens a variety of possibilities like instant backups or testing upgrades. This feature also brings Kubernetes deployments close to cloud providers, […]

Deploying Percona Kubernetes Operators with OpenEBS Local Storage

Network volumes in Kubernetes provide great flexibility, but still, nothing beats local volumes from direct-attached storage in the sense of database performance.
I want to explore ways to deploy both Percona Kubernetes Operators (Percona Kubernetes Operator for Percona XtraDB Cluster and Percona Kubernetes Operator for Percona Server for MongoDB) using local volumes, both on the […]
