Serverless is one of the biggest buzzwords of these years, and the implementation of solutions based on such architecture has been boosted by the release of AWS Lambda. This post describes a little experiment I conducted to learn more about this technology. I wanted to define and deploy a fully functional web-app (both back-end and front-end) based on RESTful services with one single file. Continue reading →
Rabbits, they are small, the are cute, they are fluffy…. and they are terrible fighters*.
Which is why evolution has favoured the skittish amongst them.

Of course running away does have a cost, and if you spend all your time running at the slightest sound you’ll expend a lot of energy and have no time to nibble at the grass and gain more**.
In REA, Amazon Web Services (AWS) is our major development and production environment, and CloudFormation (CF) is one of the best tools we’ve found to manage deployments in AWS. At the time of writing, JSON is still the only template format supported by CloudFormation; but if you search for “Programming in JSON” in your favorite search engine, the results may be very disappointing. Some developers find writing JSON templates hard and have trouble with the data format, especially when the templates are big (you can’t have comments, syntactic strictness, etc).
At REA, we encourage people to explore and find new technologies to solve problems, improve product quality and speed up deployment cycles; this freedom to explore has given us a few choices for addressing this problem.
Every week, AWS credentials leak into the wild and are used to mine bitcoins or worse.
In April 2014, DrawQuest closed down after a security breach in which their Amazon Web Services credentials were used to create hundreds of EC2 instances, probably for mining bitcoins. DrawQuest decided they could no longer trust that their core data wasn’t compromised, and closed their doors.
Wouldn’t it be great if there was a tool that could help prevent this sort of thing happening? Well, now there is — enter Credulous.
