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

LCFS: The New Container Filesystem for Modern Datacenters

Docker downloads have exceeded 5 billion pulls — that’s amazing! Whether it’s five, six, or whatever-comes-next billion, containers are fundamental to this next wave of application modernization. Each download in those billions of downloads is handled by a storage driver. Every time a container starts, the storage driver handles what is equivalent to the container’s

The Simple Button

This is going to be the shortest and simplest blog I’ve ever written. For months, I’ve been proclaiming the overwhelming simplicity and ease-of-use for Portworx. And the truth is that many of our customers have had a flawless first-day experience. But “many” isn’t enough. Portworx has to be as easy as possible for everyone. Well,

Helping ClusterHQ Customers Move Forward in 2017

2016 was a big year in the container ecosystem, including the announcement last month that ClusterHQ was ceasing operations and signaling end-of-support for their Flocker storage volume plugin. At Portworx, we were saddened to see our peer close shop. Our CEO noted that while ClusterHQ customers were right to want persistent container storage, Flocker’s connector-based

ClusterHQ Customers Are Not Wrong

One of the early innovators in the container ecosystem, ClusterHQ, just announced that they are shutting down. They were justifiably proud of their role as an early proponent of stateful containers. We agree. As containerization became a key consideration for enterprises, it was inevitable that stateful applications would be containerized. Challenging problems of providing data

Stateful Enterprise Applications with Docker

  Today Docker announced its acquisition of the file syncing project Infinit. This move underscores one of the most important issues around adopting containers in production: managing state. Just like the acquisition of Socketplane led to improvements in networking plug-ins, we see this as a great step for stateful containers that will help the entire

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

Why Should You Care About Multi-Cloud Availability?

  Today I posted a demo on the Portworx YouTube Channel that is the most powerful I’ve posted to date. I encourage you to watch it here. In the demo, I show a single Portworx elastic data service fabric spanning servers across two different cloud providers: Amazon EC2 and Microsoft Azure. Why does this matter?

Apps Don’t Want Volumes, They Want Data Services

  I’ve spent a lot of time recently with users who are deploying storage for cloud-native applications, and here’s what I’m hearing most: These cloud-native applications don’t want volumes — they want stateful data services such as persistence across machines, across availability zones, and even across clouds. They want an object store or a global

Portworx Survey: What Do Container Users Really Want from Storage?

  Many of the leading Docker images such as MongoDB, MySQL and WordPress require data persistence. But is that enough? What else are users asking from their infrastructure as they adopt containers? To find out, we surveyed 648 IT professionals at small, midsize and large enterprises. We asked about current container usage, the benefits users

Just How Easy Is It to Spin Up a Portworx Cluster?

  Traveling on the day after Labor Day should have meant long airport delays, but somehow I breezed through security with an hour to spare. So I asked myself, can I spin up a new Portworx cluster on a new cloud provider in less than an hour? Starting at 8:57, I created my new account

What Makes Portworx Unique?

  We recently sponsored DockerCon and ContainerCon. Our team agreed that they were some of the hottest tech conferences in recent memory—and a clear sign of the explosive growth of the container market. With this growth comes new vendors, and many attendees asked us, “How are you different from the other container storage providers?” Let’s

Introducing Portworx PX-Enterprise: Container-Defined Storage, with Unified File and Block

From the start, we at Portworx sought to solve the data storage needs for the next wave of container-based micro-services. One of our core design principles was to make storage radically easier to use, inspired by the power of the container experience. We then took a distributed approach to storage that is scaled out across

PX-Developer Beta: Scale-Out Storage, Container First

We all want a radically easier way to get work done. Docker has done that for applications by build once, run anywhere, and spin-up in seconds. But what about the storage industry? We put out an alpha of our container storage, after hearing from DockerCon users. Lots of user discussions, putting more miles on storage

Clouds Don’t Use Legacy Storage and Your Containers Shouldn’t Either

Large-scale clouds don’t use legacy storage arrays because of scale and costs. With containers, you have a comparable need. Containers spin-up quickly and consume storage in an on-demand manner. Enterprises want both container and storage scale-out without spending thousands of dollars for disks. All of this means that CIOs have had to compete against clouds

The 802.11 Effect in Containers

In the 1990s, the 802.11 wireless LAN standard coalesced a fragmented market of disparate technologies. Semiconductor manufacturers, device suppliers and computer vendors united behind 802.11 and created a huge wireless LAN market. Wireless LANs became ubiquitous and transformed all our lives. Standards accelerate adoption and innovation! We are ready for the 802.11 effect in containers.

Docker will be more about production IT Ops than just a developer tool

The way I see it, Docker is more than a DevOps tool – it is a better way to deploy infrastructure to applications that need state, such as SQL, NoSQL, message queues, key value databases, etc. When you want to deploy a stateful application, your choices are bare metal or virtual machines.  There are draw

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

The Case for Container Aware Storage

A micro service architecture is the championed way to design and develop large scale robust software applications. These loosely coupled software modules allow for hyper agile continuous integration and deployment. Containers are a natural fit for this application architecture. Services can be packaged as stateless containers that talk to other services for their data persistence needs. Data

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,
