The serverless brings many benefits for the deployment of web applications such as autoscaling, availability and having a very fine granularity on costs (billing per 100ms for AWS lambda).

This article makes an inventory of the cold and warm start call metrics with AWS Lambda with different code implementations. Serverless is an ambiguous term that implies that there are no more servers: this is not the case! The term adapted could have been server[management]less but…
Read moreAlright, story time fellas. TL;DR; We’re working with Terraform, layering and workspaces. This makes the standard `terraform workspace select x` pretty cumbersome and dangerous. We wrote a Ruby wrapper using Test-Driven Development. It allows us to have a tested, maintainable and efficient solution to the aforementioned issue. You can find the actual project here: https://github.com/sebiwi/terraform-wrapper If you keep reading, we’re going to talk about scripting, Test-Driven Development, Terraform and Ruby.
Read moreIntroduction When building innovative products we draw upon several models to help us follow the cycles and gauge products’ maturity levels (technological, market and use). We noticed that 3 complementary, superimposable models converge and together provide a coherence that makes the most of the various recommendations and best practices of each innovation strategy. The 3 diffusion of innovation models we’ve identified are: The Gartner model and “hype cycle” Geoffrey A.

We’d rather keep using Dockerfiles for image builds: creating a Docker image and provisioning servers with Ansible are two very different things.

Disclaimer: While the current status of Ansible Container is not clear, it seems that during the writing of this article the tool has been deprecated: https://github.com/ansible/ansible-container/commit/2fa778a7c8d1699672314ac0b89c53554f435cb7. After the limitations we noticed, we…

One of the key things which struck me at that time was that, even though each of this company was quite hierarchical, every manager must, to evolve in their career, have made a compulsory training on the field. In other words, whether you are a finance or marketing director, you have to regularly play the role of a sales…
