It has been almost one year since we launched our first Zalando App. The launch is quite a success story – in July 2013 we already achieved one million downloads after just three months in Apple’s App store and seven months in Google Play Store. Recently, we hit the two million download mark!
Last week, Mark Striebeck, Director of Engineering at Google in Mountain View spent a day at Zalando. Mark was the first guest of our “Infusion” talks within the Zalando Tech Academy, which are meant to exchange thoughts and insights on the cutting edge of internet technology. Having been in the GMail team for several years, Mark was the perfect choice – and an excellent speaker as well.
The PGConf “marathon” 2013 is over, two weeks filled with traveling are over. First step Dublin, Ireland followed up by the town of Oberhausen, Germany. We followed presentations, exchanged experiences and enjoyed the social events and now we are back in Berlin with lots of positive impressions from the growing PostgreSQL community.
At the European conference in Dublin we used the lightning talks to present our PostgreSQL monitoring setup with pg_view and PGObserver and to fuel the interest into Valentine’s talk the next day about Elephants in Fashion. Valentine dived into our PostgreSQL experience, the setup and the processes surrounding our database development and infrastructure. This promotion payed off, we got a lot of attendees to our talk and quite a few questions were raised and hallway discussions triggered. Continue reading
The tech conference season this autumn is currently in full swing and this year there was a very special (pre-)event two days before the first European TechCrunch Disrupt Conference 2013 in Berlin: The Hackathon!
Since it was the first time that the Techcrunch Hackathon took place in Europe, our team decided that we just had to support this event by offering our own contest! Besides Zalando, other great companies did a sponsorship such as Foursquare, Xing, Yammer, Paymill. Due to these partnerships, the hackathon was completely free for all the 500 international participants. The venue “Arena Berlin”, a huge indoor hall near the river Spree, was just perfect to host all hackers and create an open, bustling and productive atmosphere.
After our handy database utilities and a nifty data management tool, it’s time to officially release yet another open-source tool. The System App is used internally at Zalando’s technology department to provide an overview of our network and systems health. We’re talking about a diagramming tool which allows you to bind any external JSON data to its shapes, and create visual alerts based on rules applied to this data. We call each of these diagrams a map, and you can create as many maps as you want. For different purposes, showing different aspects of your infrastructure. Maps can be created using the UI with drag-and-drop elements, or by writing a JS script to initialize and update the map depending on your requirements.
The GOTO conference took place in Berlin for the first time – and Zalando Technology was part of it! Six Zalando developers attended the conference and we did a presentation on “Why Zalando trusts in PostgreSQL”.
All of us were really happy joining the conference and we learned a lot. For every talk I heard there was another with opposing opinions — I think it’s good to hear a broad range of opinions and the GOTO conference facilitated this. I hope to join next year’s GOTO Berlin again!
What sounds like yet another article about one of our team events, is actually a report dealing with this year’s Productcamp Berlin 2013 – an (un)conference where Product Managers shared their knowledge and experience.
What is it all about?
The basic task of product managers is specifying and prioritizing new features of their product, and managing the development – for a more detailed definition take a closer look here. Besides the need for solid technical knowledge and social skills, it is also about being good at managing the development of software products / projects, which exactly was the scope of this (un)conference.
This week we celebrate Zalando’s 5th anniversary. Zalando is one of the biggest success stories in the internet history, becoming Europe’s fastest growing company, ever.
Especially from a tech perspective we have been through a real rollercoaster ride — with an exceptional pace, always a pulse at 180 and a whole lot of fun.
A late, yet dry and relatively hot summer with a number of opportunities to celebrate Zalando’s 5th birthday has finally come to an end. Before temperatures dropped for good here in Berlin, we took one of the last warm days to throw a final and memorable party at our Schuckert Höfe offices, a historical factory complex built in the late 19th century.
Together with our colleagues of Zalando Lounge and zVentures, we had a delicious BBQ, fresh cocktails, great electronic music and a lot of fun until midnight. Various geek toys were available and allowed us to compete against each other – including table soccer, various video games and a really cool vintage Carrera slot car racing track, not to mention the fully-fledged dance floor with lights and fog machine.
A few weeks ago we introduced PGObserver, hinting at the broad use of stored procedures for accessing our data. Today, we will get into a bit more detail about how and why we have chosen a different route back then and continue to use stored procedures. To our new readers, for the Zalando E-commerce Operating System (ZEOS) platform we chose PostgreSQL to store our important data, spanning from customer order to article meta data. We did so, because back then we trusted, and still do so, into this great open source database, for its performance, reliability, and flexibility provided by a large feature set including stored procedures in multiple languages.
