High availability is becoming a de-facto requirement of today's applications. Customer-facing IT failures mean directly losing customer revenue and trust, as users have grown accustomed to easily switching service providers for more reliable ones. Lack of internal systems availability block employee productivity and add to the financial burden. Thus, it is critical to have a healthy, performant, resilient IT structure serving as a backbone of conducting your business. But there are no textbook solutions to achieving five 9s availability.

Data redundancy, computing clusters, load balancing, fail-over mechanisms, each of these individually addresses one potential issue, but none treats systems in your organisation holistically for maximising business revenue.

Silos are a clever method of grouping servers in such a way that they can be scaled both horizontally and vertically, depending on the actual application needs. Most importantly, it frees you from over-optimizing the architecture upfront, by allowing fine adjustments easy to integrate in your Agile workflow.

Excellent talk on high availability systems. Georgianna explained the problem and the solutions with nice examples from the real world. She also explained the disadvantages too which made the talk nicely balanced.

Best of all, although quite a dry topic, she didn't need to lean on funny gifs or memes to keep the talk interesting - the slides had useful diagrams and she explained things in a clear and often amusing way.

Great talk! Very visual, presenting the topic and solutions in an entertaining way, while showing deep technical knowledge on the matter.

Excellent talk and wasn't phased by difficult questions. The topic was explained well and the diagrams were great at explaining how high availability systems work.

Great talk, plenty of food for thought to take away from it. It was also rather entertaining. The Q&A was really good too.

@Georgiana Gligor:
Perhaps it would be good to include the traffic controller you use in the slides and some alternatives you would consider.
