Object storage systems can offer simple, scalable and cost-effective means of storing heterogeneous data sets. Traditionally, these systems have been designed for media, backup, and archive. However, the usage of object storage systems is increasingly expanding to...
Hybrid Cloud
Deploying Crossplane Providers with the Operator Lifecycle Manager
Crossplane is a project that strives to bring cloud infrastructure, services, and applications closer to your Kubernetes cluster in order to create a hybrid control plane. This goal is primarily achieved through the use of providers, which are standalone controllers...
Crossplane as an abstraction platform to manage and deploy service Operators
How do you manage and deploy Kubernetes Operators in the open hybrid cloud to take advantage of multiple clouds? One approach is Crossplane, a Kubernetes add-on that extends any cluster with the ability to provision and manage cloud infrastructure, services, and...
Crimson: evolving Ceph for high performance NVMe
At the time when Ceph was originally designed, the storage landscape was quite different from what we see now. Initially, Ceph was deployed generally on conventional spinning disks capable of a few hundred IOPS of random IO. Since then, storage technology has...
Using the Crossplane Operator to manage and provision Cloud Native Services
This post by the Red Hat Office of the CTO seeks to expand on previous work and further explore Crossplane as a Kubernetes Operator for provisioning, managing, configuring, and consuming cloud services. These services can then, in turn, be used to create and deploy...
Developments in Kubernetes object storage support
Object storage is fast becoming a solution of choice for storing massive amounts of unstructured data. The popularity of object storage is due in part to how it can scale efficiently. This in particular sets it apart from file and block as users can quickly...
Quantum on OpenShift – part one, an introduction to quantum computing
Many people are talking about the use and purpose of quantum computing of late, so we wanted to take an opportunity to talk about what Red Hat is doing around quantum computing. This first post will give an overview of a few of Red Hat's activities with quantum...
Managing application consistency and state during Disaster Recovery for Ceph RBD mirroring
This is the third post in our series investigating how Rook-Ceph and RBD Mirroring can be best utilized to handle Disaster Recovery scenarios. The first post in the series, "Managing application and data portability at scale with Rook-Ceph," laid some foundational...
Cloud-native software development with Virtual Application Networks
Communication between distributed software components in a cloud-native application is an important and challenging aspect of cloud-native development. This post introduces a solution to that problem using Virtual Application Networks (VANs). A VAN can be set up...
Data integration in the hybrid cloud with Apache Spark and Open Data Hub
In this post we introduce the basics of reading and writing Apache Spark DataFrames to an SQL database, using Apache Spark's JDBC API. Apache Spark’s Structured Streaming data model is a framework for federating data from heterogeneous sources. Structured Streaming...
Managing disaster recovery with GitOps and Ceph RBD mirroring
In our previous blog, Managing application and data portability at scale with Rook-Ceph, we talked about some key features of Rook-Ceph mirroring and laid groundwork for future use case solutions and automation that could be enabled from this technology. This post...
Deploying a full-service 5G network on OpenShift
During the last Kubecon North America in San Diego, a cross-vendor team of engineers from Red Hat and several other companies rolled a half-rack of servers and a self-made Faraday cage onto the keynote stage and demoed live a full 5G/4G network connected to two...
Managing application and data portability at scale with Rook-Ceph
One of the key requirements for Kubernetes in multi-cluster environments is the ability to migrate an application with all of its dependencies and resources from one cluster to another cluster. Application portability gives application owners and administrators the...
Scaling workload storage requirements across clusters
A number of multi-cloud orchestrators have promised to simplify deploying hundreds or thousands of high-availability services. But this comes with massive infrastructure requirements. How could we possibly manage the storage needs of a thousand stateful...
Red Hat and NVIDIA bring scalable, efficient edge computing to smart cities
Teams from Red Hat and NVIDIA have collaborated on creating a scalable hybrid cloud application that could revolutionize smart city initiatives such as traffic-flow monitoring and transportation management around the world. By working together, the two companies are...
Passing Go: polyglot Kubernetes Operators
Operators within Kubernetes are useful tools, designed to extend the container orchestration platform with additional resources. More directly, an Operator, sometimes referred to as custom controllers, is a method of packaging, deploying, and managing a Kubernetes...
Managing chaos in a containerized environment
Quick, name some weird stuff that’s happened to your production machines. Accidentally dropping a production database table? Rolling out a patch that enabled any user to log in with any password? Disabling a load balancer? Using a dictionary to physically keep...
Understanding and Applying Storage Federation Patterns Using KubeFed
As a cloud user, how do you avoid the pull of data gravity of one provider or another? How can you get the flexibility and tooling to migrate your infrastructure and applications as your needs change? How do you get to the future of storage federation as data agility?...
Rook Changes the Kubernetes Storage Landscape
It’s no secret that if you want to run containerized applications in a distributed way, then Kubernetes is the platform for you. Kubernetes’ role as an orchestration platform for containers has taken center stage to become a main player for automating deployment,...
Hardware Isolation in the Cloud – HIL on the Mass Open Cloud
The Mass Open Cloud (MOC) is an open cloud exchange that provides compute resources to university researchers. The virtualization infrastructure is built on Red Hat OpenStack Platform, using Foreman for provisioning and Ceph for distributed storage. But the MOC has...
