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...
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...
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...
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...
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...
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...
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...
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?...
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,...
The challenges of maintaining persistent storage in environments that are anything but persistent should not be taken lightly. My recent conversation with Ceph founder Sage Weil certainly made that clear. Thus far, the conversation with Sage has highlighted key areas...
It was not that long ago when organizations had in-house servers humming along running applications and storing data. Today, the opportunity afforded by containers means that applications can now live on a cloud platform (either public or private), or one of several...
In Part 1 of Now + Next’s closer look at the future of container storage, we examined the beginnings of the storage solution with a look at how hardware trends will affect the way storage and containers will evolve together. In this installment, Ceph Project Lead Sage...
The rise of container technology has created a new challenge for the storage industry. Within containers, applications, and computation resources are now incredibly mobile, while storage still has to remain persistent and accessible. Here’s how Red Hat is working to...
