IT latency in critical periods: keep slowness from driving customers away
IT latency in critical periods is a silent, highly destructive problem for user experience.
Unlike a full outage, latency shows up as continuous slowness, leading the customer to abandon purchases or services within seconds.
In moments of high demand, such as Carnival or the World Cup, the infrastructure is put under maximum stress.
Latency rarely appears at a single point; it is the result of small delays accumulated across different layers of the environment. Getting ahead of these scenarios is the best way to keep the business healthy.
Understanding the sources of delay in the infrastructure
To fight IT latency in critical periods, you first have to identify where the friction is happening.
- Network latency: data transport time;
- Application latency: code processing time;
- Database latency: slow queries or locks;
- Integration latency: APIs and external services.
The impact of demand peaks
As load increases, resources start to reach their limits. Without proper monitoring, requests pile up and create a cascade effect that compromises user experience.
Payment APIs and integrations: the most sensitive link
Payment APIs are external integrations and, if not well monitored, they become critical points and cause losses.
Why p95 and p99 metrics are essential
Averages hide serious problems. Metrics such as p95 and p99 show the response time faced by the most affected users, revealing intermittent failures that hit revenue and reputation.
Observability and response playbooks
Observability makes it possible to trace the whole transaction, from the application to external integrations, avoiding IT latency in critical periods.
Predefined playbooks guide fast actions, such as traffic redirection, cache adjustments or temporary scaling.
AKEN Watch: structured monitoring for latency control
AKEN Watch delivers the observability base needed to follow latency and performance in critical periods, with:
- Ready-made dashboards;
- Alerts focused on p95, p99 and critical integrations;
- Monitoring setup for infrastructure, applications and APIs, letting the client follow the environment in real time.
Models with continuous operational work can be contracted as an upgrade, according to the maturity of the operation.
Frequently asked questions about IT latency in critical periods
1. What causes IT latency in critical periods?
It is usually caused by an excess of simultaneous requests that overload processors, memory and the bandwidth of the network or of external APIs.
2. Why is payment API response time so important?
If the API is slow, the customer may think the payment failed and try again, generating duplicate charges or giving up on the purchase.
3. How does a Circuit Breaker help reduce risk?
It keeps your application from continuing to call an external service that is down or slow, preserving the resources of your own server.
4. What are p95 and p99 metrics in monitoring?
They are indicators that show the response time for the 5% (p95) and 1% (p99) of users facing the worst slowness in the system.
5. What is the difference between latency and bandwidth?
Bandwidth is the amount of data that can be sent, while latency is the time that data takes to reach its destination.
6. How does a playbook help reduce latency?
It offers a step-by-step guide so the technical team can take immediate action, such as scaling servers or resetting services, without losing time on manual diagnosis.
7. Can AKEN monitor latency in hybrid clouds?
Yes, our tools allow full visibility whether your data is on physical servers, public cloud or mixed environments.
