How Arcomix prepares its IT for Black Friday demand peaks

Arcomix asupermarket chain in Pernambuco, is preparing for Black Friday with elastic cloud computing and support activated in advance. When the server supporting the POS system and price changes crashed at peak usage, the Skyone team upgraded it in less than 10 minutes. Afterward, the IT department began requesting reinforcements before the critical date.

A supermarket's Black Friday starts on the screen of whoever is in charge of prices

For the consumer, Black Friday is a Friday of deals. For the IT department of a supermarket chain, it starts much earlier and happens in a less visible place: the system that constantly changes prices.

This is the scenario in which Andressa Silva, IT manager at Arcomix and Arcovita, a family-owned retail chain in the metropolitan region of Pernambuco, works. She summarizes the operation as follows: retail, cash and carry, and wholesale, with both physical and online stores operating simultaneously. In other words, the system needs to be available in all scenarios, all the time.

On Black Friday, according to her, the operation is frantic: prices change all the time, and each change goes through the POS and a server hosted at Skyone. Every change puts a strain on the environment.

What happens when success puts a strain on infrastructure?

Arcomix already had very good equipment. The problem was something else: retail is dynamic, sales grew, and this growth began to weigh on the database and operations. It was necessary to expand the environment to guarantee availability.

It's a common challenge for those who grow: the infrastructure that served them yesterday wasn't designed for today's volume. And, in retail, slowness appears first where it hurts the most. In Andressa's words, sales is the heart of retail and cannot experience slowness in any process.

Why has migrating to the cloud changed the game?

It was at this moment that Arcomix found Skyone. The migration to the cloud, described by the manager as something quite disruptive, brought two changes at once:

1. Speed ​​to scale. Today the team can increase resources quickly, something that, according to her, was not possible in an on-premises environment.
2. Peace of mind for management. If any incident occurs, there's a support team to assist, which she describes as very proactive.

The result is a stable environment, and this has a little-discussed effect: when IT stops putting out fires, people can focus on what they really need to do.

The day the server crashed at peak load (and was resolved in less than 10 minutes)

Stability doesn't mean nothing happens. On a Black Friday, the intense price fluctuations even caused the server to crash. More capacity was needed, and faster.

The Arcomix team contacted Skyone, and the upgrade was completed in less than 10 minutes.

Think about what this means. In a crowded supermarket, with promotions running, ten minutes is the time between a transaction progressing and a queue being stopped at the checkout. And, in a physical environment, the same upgrade would require buying, installing, and configuring equipment, a process that can take days.

After the scare, the lesson: to anticipate

The most interesting part of the story is what Arcomix did afterward. The team learned to recognize when a critical date is approaching and to prepare before the problem arises.

When they know there will be more pressure, such as at the end of the year or on Black Friday, they start to:

• Give advance notice that a critical date is approaching.
• Request more database spacebefore you run out.
• Open a support ticket to have a dedicated support team during the operation, so that any problem receives faster attention.

It's the kind of combination that makes all the difference: the resilience of the cloud, which resolves unforeseen events in minutes, and the planning, which prevents unforeseen events from happening.

Frequently Asked Questions

How to prepare your IT infrastructure for Black Friday?
Identify the most sensitive traffic flows, ensure sufficient capacity and database storage, and coordinate provider support in advance. Arcomix's case study shows that anticipation prevents problems that elasticity only solves later.

Does the cloud help handle peak demand?
Yes, because it allows for rapid resource expansion. In Arcomix's case, a server upgrade was completed in less than 10 minutes during the operation.

Does Black Friday only affect e-commerce?
No. In physical retail, the peak also puts pressure on POS systems, pricing, and databases, as Arcomix's experience shows.

Is it worth having dedicated support on critical dates?
For operations where downtime is costly, yes. Having a team on standby means that a problem is dealt with faster, and Arcomix uses this strategy during Black Friday and the end of the year.

In conclusion: tranquility is an invisible task

Anyone passing through Arcomix on Black Friday sees promotions and crowded aisles. What they don't see is Andressa and the IT team making sure prices change, the cash registers work, and that nobody has to worry about the server.

If there's one lesson from history, it's that tranquility isn't luck. It comes from having an environment that grows alongside the business, a team by your side when things go wrong, and the habit of giving advance notice. Black Friday isn't usually the day when IT shows up. When everything goes right, nobody notices they were there, and that's how it should be.

If your operation is also feeling the strain of the peak, it's worth starting with a simple conversation: what would happen to your IT department if the volume doubled tomorrow? The answer usually shows you where to begin.
