DevOpsGirls started a year ago with a bunch of enthusiastic REA people who wanted to make a difference in diversity in Tech, particularly with women who are interested in DevOps.
After running two highly engaging bootcamps we have been discussing a lot about what’s next for this initiative. REA has been an amazing incubator of the idea and has provided everything that we needed so far to kick-start the movement, but among the organisers we had a feeling that if we wanted to reach the next level we needed bigger support from other individuals and organisations. That’s difficult to do if it’s attached to a single sponsor. With the great response we have had from the industry and the beautiful experience of having external coaches joining the previous boot camp has help us determine the next step.
And so — I am super happy to announce that DevOpsGirls will become part of DevOps Australia – an organisation well know for running conferences like DevOps Down Under! Thanks to Matt Jones for the support and we really believe this is a step in the right direction and would help DevOpsGirls operate in a more effective way.
Here in Consumer Insights we have been operating Big Data processing jobs using Apache Spark for more than 2 years. Spark empowers our daily batch jobs which extract insights from consumer behaviors from tens of millions of users who visit our sites. This blog covers our usage of Spark and aims to provide some useful insights for optimizing Spark applications based on our experience.
Recently we launched a recommendation engine, which was built using AWS Serverless technology. The journey of implementing this solution turned out to be an interesting one on a number of levels. Since its deployment into production, we thought it would be a good idea to share some of our lessons.
Bucket of Data
Essentially the system transforms a very large dataset into smaller ones that are used to create audiences or data segments which are used for hyper targeted EDMs.
To get from the initial state to the final state, the data is transformed over several stages using 8 Lambdas. Continue reading
Deploying a high traffic website with zero downtime is a challenge – there’s a natural tradeoff between:
- Performance and cacheability.
- Getting updates versions of the application live.
The approach you use to manage your static assets plays a big role in this.
This post explains how we dealt with the challenges in our move from the data centre to a multi region highly available cloud-based architecture.
A Journey into Extensible Effects in Scala
This article is an introduction to using the Scala
Eff library, which is an implementation of Extensible Effects. This library is now under the Typelevel umbrella, which means it integrates well with popular functional programming libraries in Scala like Cats and Monix. I will not touch on the theoretical side of the concept in this post. Instead, I will be using code snippets to describe how you would introduce it to an existing Scala code base. This should hopefully improve extensibility and maintainability of the code. As part of this, I will demonstrate how to build a purely functional program in Scala using concepts such as
Developers have – with the advent of DevOps – been working more and more in Operations and Infrastructure. Testers however, have not.
Thus far, the testing personnel have been mostly or wholly assigned to application testing work. As SOFTWARE testers, we have only worked on software – and then mostly only on application software.
I pose the questions: What about infrastructure as code? Should that not be explicitly tested?
And: if Testers are meant to be testing the system, why then have they not explicitly been testing the whole system, infrastructure included?
I am going to make a case here for including QA in Operations and Infrastructure, by clarifying how I see the QA fitting in the DevOps world. Continue reading
