I was going through the AWS Lambda main presentation page yesterday and I started to wonder if it would be possible to create your own stack with the same featureset. First off, AWS Lambda is a stunning programming model. A cross between stateless distributed functional programming at scale (say that fast ten times if you dare) […]
Kubernetes provides a nice script to quickly deploy a small cluster on various infrastructure backends. On AWS, the documentation is a tad short about detailing how to customize the installation. By default, Kubernetes is deployed on the Oregon availability zone (us-west-2a) with a cluster size of four minions driven by a single master. The EC2 instances for the minions […]
I have been recently working with Russ Miles on coding microservices that follow principles he has laid out in the Antifragile Software book. As a simple demo we decided on using Kafka as a simple event store to implement an event sourcing pattern. The main focus of this article is to talk about how to deploy a kafka cluster and manage […]
Previously, I presented a simple web application that was distributed into several docker containers. In this article, I will be introducing the CoreOS platform as the backend for clusterizing a CherryPy application. CoreOS quick overview CoreOS is a Linux distribution designed to support distributed/clustering scenarios. I will not spend too much time explaining it here as […]
In the previous post, I described how to setup a docker image to host your CherryPy application. In this installment, I will present a complete – although simple – web application made of a database, two web application servers and a load-balancer. Setup a database service We are going to create a docker image to host our database […]
In the past year, process isolation through the use of containers has exploded and you can find containers for almost anything these days. So why not creating a container to isolate your CherryPy application from the rest of the world? I will not focus on the right and wrongs in undertaking such a task. This […]
At work, we have been using Robot Framework for all kinds of tests for a few years now and it’s proven to be the good choice. Robot Framework’s simple syntax and grammar does not scare testers away (usually). At the same time, its design makes it easy to support complex use cases as well as […]
Early on this year, a discussion emerged on the CherryPy mailing-list about the project. Most people said they loved the project but had struggled with its documentation. Though rich and extensive, it was felt it left down the project somehow by being not designed in a way that was attractive to new comers. I took […]
Recently, I was advised that WebFaction had added support for WebSocket in their custom applications by enabling the according nginx module in their frontend. Obviously, I had to try it out with my own websocket library: ws4py. Setting up your WebFaction application Well, as usual with WebFaction, setting up the application is dead simple. Only […]
I released ws4py 0.3.4 this weekend and although I had integrated support for Python 2 and 3 for a long time now, I ran into a challenge I had quite missed. Indeed, until now my Python 3 support had mainly been concerned about string handling and various compatibility modules. This has proven to work very […]
