Automating Container Storage for AWS and Packet using Terraform and Portworx (aka “Go Get Terraporx”!)

The Importance of Automation Portworx provides container-granular storage that is scheduler integrated. Working with customers running on-prem and in public clouds, the importance of automation is clear. And the one framework that customers consistently request integration with is Terraform from HashiCorp. Terraform is probably the best automation framework that allows for DevOps Programmable Infrastructure —

How to speed up docker build by making $ docker commit into a constant time operation

One of the most common questions developers ask is “how do I speed up my Docker builds”?  This post answers that question.  LCFS is a new open source storage driver for Docker, built exclusively for containers. Most storage drivers such as DeviceMapper, AUFS, and Overlay2 are based on complete filesystems designed to run entire applications.

Resize a MySQL container volume without taking your app offline

With today’s growing storage needs, DevOps teams regularly discover that they have outgrown the previously provisioned storage for their various services. Provisioning additional storage in today’s solutions would require DevOps to open a ticket for IT or storage admins to perform the task, which would end up taking hours, or even days. At the admin

What Does It Mean To Be “Cloud Native”?

“Cloud native” is an overused and ill-defined term. My take is that “cloud-native applications” adhere to these properties: They are not monolithic. Instead they are discrete, logically separable portions that are packaged and deployed on their own. Usually these are done as containers, and in some cases just as regular Linux packages. The entire application

Is It Blasphemy to Reduce Cassandra Replication?

Once Upon a Time When I was interviewing with Portworx, I may have mentioned that I knew Cassandra. Little did I know what I’d be signing up for! Fast forward a few weeks after joining, and I was asked to test Cassandra on our product. Portworx (“PX”) provides an abstracted persistent storage fabric and data

Docker storage plugin facilitates the orchestration of stateful containers

Portworx builds a software scaleout block storage solution for Docker.  We rely on commodity hardware and assume customers have existing underlying physical storage (DAS or SAN, we don’t care), from which we carve out virtual volumes for Linux containers. A fundamental question is how these storage volumes can be directly attached to a stateful application

Handling stateful Dockerized applications

I wanted to talk about how we should handle high availability of stateful applications in Docker.  Some applications handle their own availability at the application level, and some don’t.  So it can get confusing about how you provision storage to applications running in Docker: Do I rely on the application’s internal replication and disable external

Building an Application Defined Data Center using Docker

In working with building infrastructure for large data centers over the past 15 years, I’ve observed that: Infrastructure provisioning today is done distinctly and separately from application provisioning. For example, storage is provisioned first, LUNs are carved out and then attached to a host, or VM, and finally application is deployed. This complicates deployment scripts,
