Encryption at rest with Ceph

Do you have a big data center? Do you have terabytes of confidential data stored in that data center? Are you worried that your data might be exposed to malicious attacks? One of the most prominent security features of storage solutions is encryption at rest. This blog will explain this in more detail and how it is implemented in Charmed Ceph, Canonical’s software-defined storage solution.

Migrating LIVE to a Multi-Disk Clickhouse Setup to Increase Operability and Decrease Cost

Recently, my colleague Yoann blogged about our efforts to reduce the storage footprint of our Clickhouse cluster by using the LowCardinality data type. But reducing the actual usage of your storage is only one part of the journey and the next step is to get rid of excess capacity if possible. As every engineer that has worked in a cloud environment knows, growing a virtual disk is easy, but simply shrinking it back once you don’t need the amount of storage unfortunately isn’t possible.

AWS EBS Volumes: 5 Ways to Optimize Performance and Costs

Amazon Elastic Block Store (EBS) provides block storage for applications that are running in the cloud. However, not every company is getting the most out of the EBS volumes they are using. Some companies can pay too much for EBS volumes without utilizing the allocated storage and IOPS. Other organizations may pay high prices because they are using the wrong disk type for their needs. This article explains five techniques you can use to optimize the performance of your EBS workloads.

Ceph storage on VMware

If you were thinking that nothing will change in your VMware data centre in the following years, think again. Data centre storage is experiencing a paradigm shift. Software-defined storage solutions, such as Ceph, bring flexibility and reduce operational costs. As a result, Ceph storage on VMware has the potential to revolutionise VMware clusters where SAN (Storage Area Network) was the incumbent for many years.

Longhorn Launch Webinar - ANZS - 2020-06-16

This is the recording of the virtual launch event for the GA launch of the CNCF project Longhorn. When combined with Rancher, Longhorn provides DevOps teams with a lightweight, reliable cloud-native management and storage orchestration platform for any Kubernetes environment. Originally created by Rancher as an open source project in 2017, Longhorn was donated to the CNCF in 2019 as a sandbox project. On May 28, Longhorn will reach ‘General Availability’ status, providing the cloud-native ecosystem with lightweight and reliable persistent storage solution for Kubernetes.

Stateful Apps and Support of Persistent Storage

With enterprises and ISVs adopting containers and Kubernetes (k8s) to increase the agility and scalability of their applications, they would want more applications to be deployed on k8s. Applications can be a mix of stateful and stateless. Until recently, only stateless applications were supported by k8s. However, with the advent of persistent storage on k8s, stateful applications will be supported. In the pet Vs cattle analogy of service, you would want to treat the storage as cattle.

Longhorn Simplifies Distributed Block Storage in Kubernetes

Today we’re announcing the general availability of Longhorn, an enterprise-grade, cloud-native container storage solution. Longhorn directly answers the need for an enterprise-grade, vendor-neutral persistent storage solution that supports the easy development of stateful applications within Kubernetes. We’ve been working on Longhorn for almost as long as we’ve been around as a company.

Longhorn: Rancher's Journey from Zero to GA

When Frodo was commissioned on a seemingly straightforward journey to retrieve the One Ring, I doubt he realized the adventure and commitment he was embarking on. Rancher Labs started on a similarly daring journey almost four years ago. It didn’t take a wizard showing up uninvited at dinner to convince us of this. From the beginning of Rancher Labs, our founding team had a deep conviction about the importance of storage in the future of cloud-first computing.
