Ubuntu on a Dell XPS 15 9550

I have enjoyed using a Dell XPS 15 9550 for a few months now. Fantastic machine. When I got it, I tried to install Ubuntu 15.10 which utterly failed. Basically, I couldn’t even boot up the installation. I gave up and started monitoring threads on that subject. Today is the release of Ubuntu 16.10 and […]


Let’s talk about microservices

Well well… let’s talk about microservices. I have been keen on following what was going on with microservices since its inception but I have never been its most vocal champion. I don’t believe in screaming microservices like a fanboy. It is mostly counter-productive. With that being said, I see more and more people talking about […]


An asynchronous CherryPy server based on asyncio

CherryPy is a minimalist web application server written in Python. Hundreds of people have relied on it for more than fourteen years now. Recently, I’ve gained interest in the native asynchronous support Python has gained through the implementation of PEP-3156 and PEP-0492. Basically, Python now supports coroutines natively and in a friendly API interface. In addition, […]


dalamb – An AWS Lambda clone (sort of)

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) […]


Customizing Kubernetes AWS deployment settings

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 […]


Running a zookeeper and kafka cluster with Kubernetes on AWS

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 […]


Deploying a docker container of a CherryPy application onto a CoreOS cluster

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 […]


A more concrete example of a complete web application with CherryPy, PostgreSQL and haproxy

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 […]
