How to Build a High-Performance Magento 2 Store That Scales

It is relatively easy to establish an ecommerce site. However, establishing an ecommerce site which is fast, reliable, secure and simple to operate as your company expands will be significantly harder.

Magento 2 provides merchants with an extensive amount of freedom to create very complicated e-commerce websites. It is capable of handling large numbers of products, multiple storefronts, customized checkouts, integration of outside vendors, and global business practices. Freedom does provide for a long-term impact on the performance of the system and how easy it will be to maintain over time due to the development choices made.

A great-looking theme is only part of what makes a successful Magento e-commerce store. It is important to remember that all parts of your site — the front-end, extensions, integrations, host environment, and any custom coding — must be able to function together as a single unit.

When building a scalable Magento 2 store, there are a few key areas to focus on.

Start with a Clean Store Architecture

Plan first, then develop. Don’t start developing by installing extensions or changing templates.

Before you start coding, define the structure of the store, including:

• Size of catalog and types of products
• Categories & navigation
• Customer Segments
• Languages & store views
• Payment Method
• Delivery Options
• Tax liabilities
• ERP or CRM integrations
• Stock control
• Marketing & Analytics Instruments

For stores with thousands of products or multiple markets, this degree of planning becomes critical.

For instance, if a business has stores in several countries, they would require various currencies, tax laws, products, shipping methods, and content. Magento can fulfill all of those requirements, however, the system must be developed correctly from the beginning.

Bad structural decisions result in unnecessary customization later.

Select a Theme that Focuses on Performance

The appearance of a business’s website will influence customer perceptions; however, the design of that site must never interfere with the ease-of-use or performance of the site.

A quality Magento theme will have a responsive layout, the ability to configure settings logically, a clear path of navigation and be compatible with the most commonly utilized Magento features.

Developers should also try not to load scripts, fonts, sliders, animations, and other front-end components into all pages of their site without reason.

The ultimate objective of a store front is to provide an visually appealing experience for the user while minimizing the amount of unnecessary processing the user’s browser performs.

Product pages require extra care, because they frequently include image galleries, customizable choices, customer reviews, other recommended products, product recommendations, and tracking code. Any of these additional features can affect page load speed when properly designed.

The foundation of your business has to be developed as a strong theme, and then its performance within the confines of an actual retail establishment will depend on the degree to which you develop it.

Keep Modular Custom Development

Magento offers extensive customization options, but editing core files directly can lead to serious maintenance problems.

Custom functionality should mostly be done using properly structured modules, plugins, observers, APIs and supported extension mechanisms.

That makes future updates much easier.

Let’s say a merchant wants a custom pricing feature for wholesale customers. At first glance, editing the core pricing files of Magento might seem like the fastest option. But, those changes may be overwritten or cause conflicts with future platform updates.

A dedicated custom module is a better and more maintainable approach.

Companies with more sophisticated functionality often resort to specialists providing Magento 2 development services to build these customizations on Magento’s architecture rather than relying on quick fixes that are difficult to maintain.

For example, Laconica is a partner for Magento projects that go beyond visual storefront changes to integrations and custom eCommerce functionality.

Be Choosy About Extensions

Extensions may significantly shorten development time, but having too many can create new problems.

Every extension adds more code to the store. Some might add further database queries, JavaScript files, scheduled jobs or dependencies.

Before you install an extension, developers should ask themselves a few questions:

• Is this feature already available in Magento?
• Is the extension still maintained?
• Is it compatible with current Magento version?
• Will it conflict with modules that already exist?
• How much extra processing does it add on the front or back end?

A store with 20 well chosen extensions can be easier to maintain than a store with 80 extensions that are installed for minor features.

Also, removal of unnecessary modules reduces the number of components that need to be checked during Magento upgrades.

Enhance the Product Experience

Customers should be able to go from browsing to buying with no unnecessary friction.

Product pages require enough information to enable customers to make confident purchasing decisions, and category pages need to be structured in a clear way for products.

Usually includes:

• Product images of high quality
• Transparent pricing
• Stock availability
• Product selection
• Sufficient descriptions
• Shipping Info
• Reviews as appropriate
• Standard Calls To Action

Mobile usability calls for particular focus.

The product page is going to look great on your PC/Mac monitor, however it might be hard to see/use with so many different product options, buttons, pop-ups, and image gallery that have been “squished” onto such a small display.

The use of testing real customer experience across several screens allows you to find problems with your design which can be very hard to spot when you are developing on your computer.

Magento Performance Focus

Performance optimization should be part of the development process, not something you do after launch.

Magento stores hold large amounts of catalog, customer, pricing and order information. As you have more traffic and products, inefficiencies in configuration become more apparent.

Developers should pay attention to improvements in areas like caching, image optimization, delivery of JavaScript, database performance, server configuration, indexing, and third-party requests.

Production stores should be configured differently than dev environments. When the website goes live you should not leave on debugging tools, excessive logging, or development settings.

Testing a variety of page types one at a time is also helpful.

For example, don’t judge your performance just on the homepage — evaluate your homepage, category pages, product pages, search results, cart, and checkout.

Performance bottlenecks on each page can be completely different.

Checkout Is A Mission-critical Application

Checkout is one of the most commercially important parts of any eCommerce website.

Even minor issues can directly impact revenue.

Developers should test thoroughly:

• Checkout as a guest
• Registered customer checkout
• Promo Codes
• Shipping calculations
• Payment gateways
• Calculations of tax
• Address verification
• Order Acknowledgment
• Transactional e-mails

Tests should include successful and unsuccessful payment scenarios.

For instance, when a customer’s payment is declined, they should be given useful feedback instead of a general technical problem notification.

Checkout customization should also be carefully evaluated. Adding additional fields or complex steps adds difficulty to the customer’s experience, as well as added maintenance requirements.

Plan Your Third-Party Integrations Carefully

Today’s eCommerce stores rarely exist in isolation.

Magento might have to talk to payment processors, shipping platforms, warehouse systems, marketplaces, accounting apps, ERP software, CRM platforms and marketing tools.

Proper error handling for reliable integrations.

The store should not lose its key order and/or inventory information when a third-party service becomes unavailable for a short period of time.

Developers will have to choose a single system to use as the source of truth for every type of data.

In another example, if inventory levels are being tracked using an ERP system, then Magento cannot use its own internal tracking systems to create conflicts with the ERP’s tracking system.

This is even more crucial when organizations expand through multiple warehouses and sales outlets.

Laconica, along with other seasoned Magento development teams for these types of projects, will usually treat both the storefront and the corresponding business systems as one unified eCommerce environment.

Incorporate Security and Maintenance into the Project

The launch of the website is not the end of the Magento development.

The platform, extensions, integrations, server environment and custom modules all need to be maintained.

Store owners should have a process to:

• Apply security updates
• Perform Magento updates
• Check extension compatibility
• Maintain backups
• Monitor errors
• Test payment functionality
• Verify integrations
• Review performance

Ideally, updates will be tested in a staging environment before pushing to the live store.

This minimizes the chances of extension conflicts or checkout issues after the customers are already on the upgraded website.

Test Before Each Release

Quality assurance shouldn’t just be pages loading successfully.

Developers should test full customer journeys.

A practical test could start with searching for a product, clicking on its page, selecting an option, adding it to the cart, applying a discount, choosing shipping, paying, receiving a confirmation and then checking the resulting order in the Magento admin.

Testing should be done with various browsers, screen sizes, customer groups, payment methods and product types where applicable.

The more complex the store the more important repeatable testing becomes.

Final Thoughts

A scalable Magento 2 store is created with many smaller technical decisions rather than just one large feature.

A flexible theme is an excellent way to start with a strong visual foundation, however, there are many aspects to consider after the theme has been selected. The length of time that you will have an active eCommerce platform is directly related to the way in which you build it. When you create your eCommerce platform using high-quality coding practices and select suitable extensions for extending its functionality, optimize its speed, connect it to other software, deploy it securely, and continually maintain it, you are creating a far stronger eCommerce platform.

The best development approach also accounts for future growth. Today’s solution that works for a small catalog shouldn’t artificially constrain the business as traffic, product count, markets, or integrations grow.

Merchants who think of Magento development as a continuous technical effort, rather than a one-time website build, can create stores that are easier to manage, faster for customers, and more prepared for future growth.
