Anyone who sets CPU and memory limits for Magento containers by gut feeling either overprovisions expensively or risks outages during traffic spikes. This article shows how Magento container sizes are systematically derived from PHP-FPM pool sizing, real memory demand per worker, and actual traffic patterns, then validated with load tests.

Defining, monitoring
and debugging cron jobs

Many Magento problems look at first glance like data or indexer issues, but are actually cron problems. Teams that plan and observe Magento 2 cron jobs properly prevent silent failures in emails, reindexing, synchronizations and imports.

1. Why cron jobs matter so much in Magento 2

Magento 2 cron jobs are the backbone of many background processes. Reindexing, email delivery, newsletters, price rules, export runs, scheduled updates, cleanup jobs and integrations all rely on tasks being executed regularly and reliably. When cron fails, the system

A backup is only a backup once it can actually be restored. We show how a resilient backup strategy and disaster recovery work together for Magento 2: RTO and RPO as the governing metrics, automation, offsite storage and regular restore drills.

Any agency maintaining custom Magento 2 modules across several client projects cannot avoid a private Composer repository. Instead of distributing modules manually via FTP or a zip file, a private Composer repository makes them installable through composer require, versioned through git tags and with full dependency resolution against magento/framework. This article shows how to build a solid distribution infrastructure, from the repositories configuration through a self hosted Satis instance to a secured CI pipeline.

Resolving merge conflicts in the terminal means manually searching for conflict markers in the file, understanding them, and making a decision, without any visual context. The 3-way merge tool in PhpStorm shows your own version, the incoming version, and the common ancestor at the same time, which makes the decision far easier and reduces mistakes during conflict resolution.

The Percona Toolkit is a collection of command-line tools that fills exactly the gaps MySQL leaves open: schema changes without locks, systematic slow query analysis, and reliable replication consistency. Teams that use these tools deliberately against a Magento database gain control over areas that would otherwise only be manageable through risky manual intervention.

Anyone extending the product detail page in the Hyvä theme should reach for layout XML, ViewModels, and Alpine.js components, not Fotorama plugins or Knockout templates. This guide uses concrete code examples to show how gallery, tabs, and custom attributes fit cleanly into the existing Hyvä block system, including GraphQL integration, performance optimization, and a CSP-compliant deploy sequence.

Product galleries with multiple images, a zoom feature, and carousel navigation are among the most complex building blocks of a product page. Adding alt text alone while forgetting keyboard operation, focus management, and screen reader announcements results in a gallery that stays unusable for many groups of users. This article shows a complete, field tested pattern for accessible product galleries in Magento and Hyva.

GraphQL authorization does not end at the query check. Sensitive fields such as email addresses, order histories, and admin-specific data must be secured at the field level, inside the resolver context, not just in the schema. This article shows how that works in practice.

Magento relies on cron for indexing, email dispatch, and cleanup tasks, yet without careful group configuration the cron_schedule table grows unchecked and single jobs block the entire queue. This article shows how to separate cron groups properly, spot long running jobs, and replace heavy synchronous tasks with message queue consumers so the store stays stable under load.
