Our engineering rules — Inside GetYourGuide I VolHotels


Construct resilient methods

Construct methods that adapt to vary and proceed working when unknown challenges happen.

Construct easy, single-purpose providers

Small providers have clear possession, are simpler to keep up, change, and handover.

Use clear interfaces

The within of our parts are versatile and the interfaces we expose are uncomplicated. Make investments time in getting them proper — it pays off.

Observe worldwide requirements

Worldwide communities are doing job setting requirements. We observe these requirements to keep away from lengthy inner discussions and to keep up a unified method of doing issues. New methods ought to all the time observe worldwide requirements.

Write code for the reader

Code is learn extra typically than it’s written. We save time as a corporation by writing code that’s clear, simple, and simply comprehensible.

Depart code higher than you discovered it

We repeatedly enhance our code base by performing minor refactorings and sharpening the items we work with. Discovering one thing in a poor state isn’t an excuse for making it worse. We solely change code when it’s wanted — and once we change it, it’s all the time for the higher.

Measure the impression of all the things you do

If we don’t know the best way to measure the impression of one thing we shouldn’t begin to work on it.

Use clear, correct, and well-defined metrics

Spend time defining, aligning, and implementing metrics — it’s completely price it. Complicated metrics definitions waste time.

Make knowledge accessible

Our skill to innovate and enhance relies on getting access to correct, well-formatted knowledge. Our prime precedence once we’re designing methods is defining the best way to finest expose knowledge for analytics and progressive options.

Take full possession of our functions and providers

You construct it, you run it. The staff creating a service is liable for defining service degree agreements (SLAs) and supporting the service in manufacturing. This ensures {that a} service or performance is simple to debug and function.

Know our methods’ well being at any given time

We make investments effort and time into monitoring our providers and implementing well being checks. Now we have glorious monitoring and alert methods in place.

Be taught quick and implement appropriately

We lower corners to get a studying however we don’t lower corners within the implementation that follows.

Deal with massive issues via iteration

We don’t postpone or hesitate in terms of fixing bigger issues in the event that they maintain excessive enterprise worth. We method these issues in small steps and iterate to attain change.

Use the best software for the job

We take into consideration long-term advantages and wager on mature applied sciences. As for brand new applied sciences — we allow them to show themselves within the trade first. We’re fast-followers, not early-adopters.

Further know-how comes at an extra price

We restrict the quantity of effort wanted to assist, replace, and study our tech stack. When selecting to implement one thing, take the total price into consideration and goal to unravel the issue with supported applied sciences first.

Leverage open-source as a lot as attainable

We’re not right here to reinvent the wheel. We leverage open-source applied sciences as a lot as attainable.

Use gradual rollout and monitor every step

The true check of high quality is to run issues in manufacturing. By doing gradual rollouts and monitoring all the things we ship, we will shortly type an understanding of how issues work in the actual world whereas limiting the blast radius of errors.

Write assessments to save lots of time and keep away from repeating errors

We cowl important performance with well-written assessments. We add assessments once we discover bugs. This helps us keep away from regressions.
