Docker Hub rate limits

So, the 2nd of November has been and gone, and Docker are now enforcing Docker Hub pull rate limits... have you been caught out yet ? I know many have...

Radically Different Storage Solutions

Storage is Changing; analytics, file stores, research data, disk to disk backups and other new workloads are placing a strain on traditional IT storage technology. New workloads demand new protocols and APIs like S3, Swift and Hadoop, but it’s not always silos.

CI/CD for Docker Environments

One of the great benefits of Docker is that it enables a seamless CI/CD process; Containers are simply a running read only instance of a Docker Image, and updating a container is as simple as updating the image file and then redeploying the container from the updated image.

Containers have become one of the major themes in the IT industry, following the rise to prominence of Docker and its platform. The technology has found popularity because it meshes well with a need for greater efficiency, reduction in IT costs, and increasing agility in development and IT operations.
