Skipper is the open-source HTTP router we’ve created to help us rebuild the infrastructure behind Zalando’s customer-facing Fashion Store (“the Shop”). Developed with Go, it’s “go get” compatible and serves as a common entry point in front of the Shop’s service components. Skipper can be useful for non-Zalando teams who are trying to deploy a microservices architecture and want (or need) to decouple routing from service logic.

Big data has taken over many aspects of our lives and as it continues to grow and expand, big data is creating the need for better and faster data storage and analysis. Apache Hadoop and Apache Spark fulfill this need as is quite evident from the various projects that these two frameworks are getting better at faster data storage and analysis. These Apache Hadoop projects are mostly into migration, integration, scalability, data analytics, and streaming analysis.

Hadoop has continued to grow and develop ever since it was introduced in the market 10 years ago. Every new release and abstraction on Hadoop is used to improve one or the other drawback in data processing, storage and analysis. Apache Hive was introduced by Facebook to manage and process the large datasets in the distributed storage in Hadoop. Apache Hive is an abstraction on Hadoop MapReduce and has its own SQL like language HiveQL.

"Modern motivational psychology says that employees in the knowledge economy are motivated not by carrots and sticks but by purpose, not by tasks but by mastery. Similarly, Simon Sinek, author of the bestseller Start With Why , argues that the problem with typical job ads is that they skip over the purpose: 'They are all about the what, and not the why.

KOKOWINKA * is a Mobile First web app I’ve created that sells fashion items at a discount (starting at 30 percent) to Spanish consumers. It works like this: A customer purchases an item featured by an online retailer like Zalando, then the retailer pays me a reward (up to 15 percent of the selling price). As the affiliate marketer, I don’t have to worry about purchase payments, refunds or shipping.

Senior Software/Data Engineer Hunter Kelly of Zalando’s Dublin Fashion Insights Centre presented at this week’s Clojure/Conj on how we’re using Clojure and MLib to understand fashion in a more quantitative manner. Hunter’s talk — "Using Clojure+Spark to Find All the Topics on the Interwebs"— centered on our efforts to harness data from crowd-sourced websites such as DMOZ and Common Crawl , which enables us to explore methods of categorising the web into a set of known fashion-related topics.

Recently my team realized that tables in one of our PostgreSQL databases were showing colossal amounts of bloat: up to 40 out of 54 GB total (75%) for bigger tables, and up to 95% of 17 GB total for smaller ones. Having accurate estimates is important to make certain database administration decisions aimed at reclaiming disk space and improving database performance, but these numbers were something very unusual, so we wanted to investigate first.

ETL and ELT are some of the most common data engineering use cases, but can come with challenges like scaling, connectivity to other systems, and dynamically adapting to changing data sources. Airflow is specifically designed for moving and transforming data in ETL/ELT pipelines, and new features in Airflow 3.0 like assets, backfills, and event-driven scheduling make orchestrating ETL/ELT pipelines easier than ever!

Last month my colleague Igor Ramadas and I attended ForgeRock’s Identity Summit in London, where we presented a talk on Zalando’s efforts to enable business continuity while migrating to the cloud. With automation in mind, we showed how using (some) coding tweaks makes it possible for two different worlds to communicate securely: Our new cloud apps, based on STUPS and Amazon Web Services; and our legacy apps, which reside in our datacenters.
