Chaos engineering setup
We set up chaos engineering — controlled injection of failures (disabling a service, delays, loss of a node) to see in advance how the system behaves in an outage and find weak spots BEFORE a real incident. So that you test resilience in practice instead of hoping 'it will hold'. Honestly upfront: chaos engineering REVEALS weak spots through controlled failure, but does NOT fix them (findings are separate work), and it suits only mature infrastructure with backups, monitoring and recovery — on a fragile project it can itself cause a real outage.
Chaos engineering setup — overview

Chaos engineering setup is the introduction of a practice of controlled experiments on resilience: we formulate hypotheses ('if the database goes down — the site should show a fallback, not collapse'), safely inject managed failures (disabling a dependency, network delays, node failure, load), observe the behavior and record what broke. We start on staging/a limited scope and only then, carefully, move closer to production. Honestly about the role, this is key: chaos engineering is a tool for DETECTING weak spots, NOT eliminating them: the experiment shows the system handles a failure poorly, but fixing what is found (redundancy, timeouts, retry, graceful degradation) is separate engineering work. Honestly about the prerequisite, this is critical: chaos engineering is for MATURE infrastructure. You need working backups, monitoring, clear recovery and at least basic fault tolerance. On a fragile project without these, injecting failures will itself turn into a real outage — so if the foundation is missing, we will honestly say 'too early' and recommend backups/DR (770) and monitoring first. Honestly about risk: even a careful experiment carries a risk of impacting real users — so we strictly control the blast radius, start small, have a 'kill switch' and a rollback. Honestly about practice: this is not a one-off 'broke it once' setup, but a regular discipline — the value is in repeatability. Honestly about the result: you get a list of real weak spots and priorities; the value materializes only if you fix something based on the findings. Honestly about access: access to the infrastructure and risk approval are needed. An important boundary: this is chaos engineering (testing resilience through failures), while backups/DR themselves are 770 and monitoring is separate. Picture this: instead of 'we hope it holds on a failure' — you know in advance exactly what will break and have time to fix it. The base price starts from 30,000 ₽; it depends on infrastructure maturity and the scope of experiments.
Problems we solve
- It is unknown how the system will behave on a real failure.
- 'Fault tolerance' exists on paper, but no one has tested it.
- Outages reveal weak spots suddenly and at the worst moment.
- No practice of regular resilience testing.
What's included in the Chaos engineering setup service
- Assessing infrastructure maturity (whether it is ready for chaos at all)
- Formulating resilience hypotheses
- Safe controlled failures (with blast-radius limitation)
- A 'kill switch' and fast experiment rollback
- Recording weak spots and priorities
- Indicating boundaries (detection, not fixing; maturity needed)
- Starting on staging, careful approach to production
- Handing over findings and review with you
What you get
- It is visible what will really break on a failure — in advance
- Resilience weak spots found before an outage
- A practice of tested, not paper, fault tolerance
- A priority list for fixing (the fixing itself — separate)
How the work goes: steps
- We assess infrastructure maturity; if too early — we say so honestly and recommend a foundation
- We formulate hypotheses, inject controlled failures on staging
- We record findings, carefully approach production, review with you

FAQ
Won't this bring our site down?
There is always a risk of impact — so we work strictly controlled: we start on staging, tightly limit the blast radius, keep a 'kill switch' and a rollback. And most importantly: chaos engineering is appropriate only on mature infrastructure with backups and monitoring. If the foundation is missing — we will honestly say it is too early and will not risk your production.
Will the system become resilient after the experiments?
The experiments themselves do one thing — they SHOW weak spots. The system becomes more resilient only if you fix something based on the findings (redundancy, timeouts, graceful degradation) — that is separate engineering work. Honestly: chaos engineering is diagnostics under load, not an automatic cure.
Do we even need this?
Not everyone does. Chaos engineering is justified for mature projects where downtime is costly and there are already backups, monitoring and basic fault tolerance. For a small or simple site it is premature — the foundation first (backups/DR, monitoring). We will honestly assess your situation and will not sell a practice you do not need yet.
