Scalable WordPress Hosting for High Traffic Websites

Scalable WordPress comes as a solution when your website grows and it needs to adapt by scaling its resources to increased levels of traffic, without breaking its performance.

In this article, We’ll look at what scaling is and how it can benefit your business’s high-traffic website. We will also discuss the features of scalable WordPress hosting and how we implement them at Pressidium.

Anyone who has a website understands the importance of growth. Without growth your site languishes, it becomes outdated and it is eventually forgotten. This is why you put so much effort into creating quality content, promoting that content, and getting your information in front of the people that matter. You want to grow your audience, build a community, and generate interest.

Growth can come with a downside though as it may lead to increased traffic. Now let’s see how this can impact your business.

What Scalable WordPress Hosting Prevents

Events like product launches, marketing campaigns, or sudden viral content can cause unexpected spikes in traffic. Without the ability to scale appropriately, the website may struggle to handle the sudden influx of visitors, leading to performance issues and even downtime and unavailability.

Any of these consequences may harm your website’s value in multiple ways:

Poor User Experience and Loss of Revenue

As your traffic increases, the website may become sluggish and slow to respond. This results in a frustrating user experience, with longer loading times and delays in accessing content. Visitors are likely to lose patience and abandon the site. This impact on user engagement will lead to a potential loss of customers or readers.

Especially in e-commerce websites, this kind of poor performance can directly impact sales. When the site struggles to handle a surge in traffic, potential customers may encounter difficulties completing transactions or accessing critical product information. This can result in lost sales opportunities and revenue.

Reduced Search Engine Ranking

Search engines consider website performance and speed as ranking factors. Inadequate scalability, as said, leads to slower page loading times, negatively impacting the site’s search engine optimization (SEO) efforts. As a result, the website may rank lower in search results, leading to decreased organic traffic.

Damage to Brand Image and Business Growth

A slow and unreliable website reflects poorly on the brand’s image negatively affecting your business reputation. Visitors may perceive the company as unprofessional, leading to a loss of trust and credibility. Negative perceptions can be hard to overcome and may drive potential customers away to competitors with better-performing websites.

This may further limit the ability to reach new audiences, expand into new markets, and achieve business objectives.

Increased Infrastructure Costs

Without proper scalability planning, website owners might be forced to make reactive investments in upgrading hosting infrastructure or purchasing additional resources. This reactive approach can result in higher costs compared to a proactive and planned scalability strategy.

How Scalability Solves the Problem

As a website grows and attracts more visitors, it’s crucial to ensure that the site can handle the increased load and continue to provide a smooth user experience.

Scalable WordPress Hosting solution

WordPress scaling offers the room and flexibility to quickly adapt to the changes of an influx of hits. With scaling, your website can seamlessly utilize extra resources and avoid all the risks above.

Without being able to scale, any WordPress website hosted in a standard environment and not with an Enterprise WordPress provider simply won’t be able to cope with the demand of high traffic. This translates to a significantly negative impact on your site’s performance that will consequently harm your business.

Let’s examine the features that provide a scalable WordPress website and how they mitigate the problem.

Key Features of Scalable WordPress Hosting

Scalable WordPress hosting comes with a range of key features designed to accommodate the growth and increasing demands of your website.

Hosting Infrastructure

While shared hosting plans might work well for small websites, as traffic grows, it’s advisable to switch to Virtual Private Servers (VPS), dedicated servers, or cloud hosting solutions. These offer more resources and flexibility to handle increased traffic.

Cloud hosting offers the flexibility to scale CPU, RAM, and disk space on demand. You can increase or decrease resources based on traffic fluctuations, making it an ideal choice for rapidly growing websites.

Virtual Private Server (VPS) hosting provides dedicated CPU and RAM resources in a virtualized environment. It allows you to upgrade your VPS plan to access more resources as your site’s needs evolve.

With a dedicated server, you have full control over the hardware resources, allowing you to customize and upgrade CPU, RAM, and disk space as necessary.

Flexible Resources

A Scalable WordPress hosting solution allows you to adjust your server resources (CPU, RAM, storage) based on your website’s changing needs.

The CPU (Central Processing Unit) is the brain of your server, responsible for executing instructions and processing data. As traffic to your website increases, the server receives more requests that require processing power. A powerful CPU can handle a higher number of concurrent requests and execute server-side tasks efficiently. When your site experiences spikes in traffic, having sufficient CPU resources ensures that your server can process requests promptly and prevents performance bottlenecks.

RAM (Random Access Memory) is used to temporarily store data that the CPU needs to access quickly. It acts as a working memory for the server. When a visitor accesses your website, various elements like database queries, PHP scripts, and web server processes require RAM to function effectively. As traffic grows, more RAM is required to handle multiple simultaneous requests. Inadequate RAM can lead to slow response times and potential crashes, especially during traffic spikes.

Disk space refers to the amount of storage available for your website’s files, databases, media, backups and other data. As your website scales, it accumulates more content and user data, increasing the demand for disk space. Running out of disk space can lead to errors, data loss, or even website downtime. Ensuring sufficient disk space allows your site to grow without interruption and allows you to store and serve content seamlessly to users.

Upgrading these resources is usually a straightforward process. You can perform upgrades through a control panel or dashboard, without the need for complex server migrations.

Caching and Content Delivery Network (CDN)

Implementing caching mechanisms can significantly improve performance and reduce the load on the server. At Pressidium, for example, we implement advanced caching practices like OpCache, Object Cache, or MySQL Query Caching and mitigate issues with Multilayer Caching.

A CDN helps distribute your website’s static assets (images, CSS, JavaScript) across multiple servers worldwide. This reduces server load and improves page load times, especially for users in different geographic locations.

Many scalable hosting providers offer seamless integration with Content Delivery Networks. CDNs distribute your website’s static assets (images, CSS, JavaScript) across multiple servers worldwide, reducing server load and improving page load times for visitors in different regions.

Database Optimization and Load Balancing

The database is a critical component of a WordPress site. Optimizing database queries, using indexes, and cleaning up unnecessary data can enhance performance and prevent bottlenecks as traffic increases.

In high-traffic scenarios, load balancing distributes incoming requests across multiple servers to ensure even resource utilization and prevent overload on a single server.

Scalable WordPress hosting often employs load balancing, which distributes incoming traffic across multiple servers. When traffic increases, the load balancer directs requests to available servers, preventing overload on a single server and ensuring a consistent user experience.

Vertical and Horizontal Scaling

When scaling WordPress, there are two different ways to add computing resources to your infrastructure:

Vertical scaling (aka “scaling up”) refers to scaling by adding more power (e.g. CPU, RAM) to an existing server machine. So, you might choose to vertically scale to meet the increasing demands of your WordPress site for the reasons we discussed in the resources section above.

Scaling a website horizontally (aka “scaling out”), however, means adding more machines to your pool of resources that can all serve your website. Horizontal scaling allows your WordPress site to distribute traffic across multiple servers. As traffic continues to grow, it may get busier and put more strain on the servers. To handle this increased traffic, you can use horizontal scaling.

So, if a server goes down, you have N-1 servers that still serve your website. There’s no downtime, and no one notices anything.

At Pressidium we utilize both scaling strategies, horizontal and vertical, and depending on your specific business case we choose the optimal solution. You can read more about this further down in the article.

Monitoring and Security

Scalable hosting providers typically include performance monitoring tools that allow you to track server usage, response times, and other critical metrics. This enables you to proactively identify and address potential bottlenecks before they impact your website’s performance. Here is an example of how our customers can see their performance analytics through their Pressidium dashboard:

WordPress scalability should also not compromise security. Implementing strong security measures, such as firewalls, DDoS protection, and regular updates, is essential to ensure a safe environment for both your website and your users.

Auto-scaling capabilities

Auto-scaling in the WordPress Managed Hosting industry refers to the ability of a hosting provider to automatically adjust the resources allocated to a website based on its changing needs on real-time traffic. This means that if a WordPress site experiences sudden high traffic, the hosting provider can apply scaling automatically to handle the increased load. When traffic subsides, it can scale down, optimizing cost efficiency.

Apart from avoiding downtime or performance issues, auto-scaling also ensures that website owners only pay for the resources they use, rather than having to purchase a fixed amount of resources that may not be fully utilized.

In Managed WordPress Hosting, auto-scaling typically involves the use of technologies such as load balancers and auto-scaling groups, which automatically distribute traffic across multiple servers and allocate additional resources as needed. 

High availability and Redundancy

A redundant infrastructure minimizes the risk of downtime. Scalable WordPress hosting solutions often provide redundancy and failover mechanisms. If one server fails, the traffic is automatically routed to a healthy server, minimizing downtime and ensuring continuous availability.

We understand that all the above may be a lot to process. That’s why we provide some valuable tips on how to evaluate a hosting provider before buying a plan.
