CDN integration to elevate website performance 

Bluehost differentiates itself by seamlessly integrating a Content Delivery Network (CDN) into all its plans, significantly enhancing website performance.  

A CDN consists of strategically positioned servers worldwide, storing and delivering site content from the nearest server to the website visitor’s location. This results in quicker load times, regardless of a user’s locale, thanks to shorter data travel distances.  

Bluehost’s integration of CDN directly in our plans demonstrates our dedication to offering one of the fastest web hosting for WordPress. We primarily run independent single-node, multi-tenant LAMP servers with global CDN and SSL certificates. Unlike other hosting providers, we make sure this powerful tool is available across our entire hosting spectrum – from shared to advanced plans – enhancing website speed and accessibility for all hosted on our platform. 

Boosting performance with Object & Opcode caching 

At Bluehost, our focus is on enhancing website speed. We achieve this by directly integrating object and opcode caching into all plans. This ensures that every user benefits, no matter which hosting option they select. By incorporating object caching, which adeptly stores frequently accessed data such as posts and user information in a high-speed cache, we dramatically reduce redundant data processing. This translates to enhanced website performance, yielding faster loading times and elevated user experiences. 

Additionally, our systems also feature opcode caching, saving compiled PHP in RAM to expedite processing for quicker and more efficient responses to subsequent requests within the same application. 

Moreover, customers can easily take the lead in enhancing hosting performance too by optimizing their images and scripts. With our commitment, you gain substantial power to enhance your website’s performance without daunting tasks. 

Faster storage & quicker loading with SSD 

SSD storage, short for Solid State Drive storage, is a type of data storage technology that uses NAND-based flash memory to store data. Unlike traditional Hard Disk Drives (HDDs), which use spinning disks to read and write data, SSDs have no moving parts, so it significantly enhances speed, allowing for near-instant data retrieval and faster data transfer rates. This translates to quicker loading times for websites, applications, and files, leading to an improved user experience. 

Talking about instant data retrieval, SSD storage significantly reduces latency, making it particularly beneficial for applications that require quick data retrieval, such as databases and content management systems. This reduction in latency contributes to faster response times, enabling websites to handle higher levels of traffic without sacrificing performance. 

Furthermore, SSD storage enhances reliability by reducing the risk of mechanical failure associated with traditional HDDs. The absence of moving parts minimizes wear and tear, contributing to a longer lifespan and increased data integrity. 

In essence, SSD is particularly vital in safeguarding critical data, making it a choice that not only heightens performance but also provides a robust foundation for maintaining data integrity and access over the long term. 

Bluehost take a prominent stance in this domain by integrating SSD storage across all hosting plans, ensuring that your data is stored on high-speed drives. This enables websites to have increased reliability, faster loading times, smoother performance, and an overall enhanced hosting experience for all users. 

Whether you’re hosting a personal blog or a resource-intensive eCommerce website, your data is stored and retrieved swiftly, contributing to a seamless user experience. 

Elevating WordPress with the latest PHP advancements 

PHP, or Hypertext Preprocessor, is a scripting language used in web development. The latest PHP versions notably boost both speed and security. These versions are optimized for faster code execution, resulting in quicker website loading times. Additionally, the latest PHP versions come with improved security features and bug fixes, helping safeguard websites from potential threats and vulnerabilities. 

The latest version of PHP, PHP 8.2, released on December 8, 2022, and is currently the most up-to-date version.  PHP 8.2 focuses on streamlining developers’ experiences, introducing simplifications in coding processes and phasing out older functions. Upgrading to the latest PHP version enhances site security. It also helps you familiarize yourself with the updated syntax for smoother development. 

Bluehost stands out by offering the advanced PHP 8.2, surpassing many industry providers. While WordPress currently recommends PHP 7.4 and aims to move users to PHP 8.0, Bluehost’s current goal is to ensure a seamless move to PHP 8.2 (refer chart below). We use a well tested QA process to provide newer versions of PHP to customers as their sites are able to support those versions.

Stay current with auto upgrades for WordPress 

Auto upgrades are crucial because it makes software setup easy for users. It replaces complex manual steps with a single click, saving time and reducing errors. This is especially important for platforms like WordPress, ensuring quick and hassle-free use for everyone. 

Auto install enhances performance by ensuring that the software, such as WordPress, is installed correctly and optimized for the server environment. It eliminates potential user errors during manual installation that could lead to performance issues or compatibility problems. Additionally, auto install often includes essential optimizations and configurations that are set up automatically, improving the overall speed and efficiency of the software. This results in a smoother user experience, faster loading times, and better website performance. 

At Bluehost, we’re at the forefront of offering convenient solutions for WordPress users. With our one-click auto install feature, setting up WordPress websites is as simple as a single click. For example, the latest WordPress version of 6.3 is installed automatically out of the box. New versions are made available to existing customers promptly. Over half the platform upgrades within 24 hours of a new version coming out. Older versions (with WP updates disabled) are updated, when possible, without disruption. 

We take it a step further with our managed WordPress hosting services. We handle the technical complexities, ensuring that websites remain up-to-date, secure, and optimized for performance. This means you can focus on creating content and growing your online presence, while we take care of the technical details. 

Optimizing hosting performance with better compute resources 

In hosting, RAM (Random Access Memory) is swift-access memory that accelerates task processing, while CPU (Central Processing Unit) functions as the computational core executing instructions. Both RAM and CPU resources are vital for smooth performance in such hosting setups. 
Better compute resources are needed when websites or applications face increased demand. This includes higher traffic, complex operations, or resource-intensive tasks. Upgrading to more capable resources, like improved RAM and CPU, becomes essential to maintain optimal performance during these scenarios. 

Our higher plans come with enhanced compute resources, offering extended CPU time and the ability to manage more concurrent web server connections. Additionally, we utilize opcode caching and object caching, reducing the resources and time needed for processing requests. This efficiency enables accomplishing more with fewer resources. 

We differentiate ourselves from other providers by not imposing per-user RAM limitations, and we align with the recommended per-process RAM allocation by WordPress. 

How does this benefit you as a user? When requests surpass immediate handling capacity, they start queuing, leading to longer load times. With sustained demand, the queue grows, and delays compound. In the long term, as the website traffic grows, so does the demand. A more popular site naturally requires increased resources. And in the short term, peaks in traffic, such as viral posts or product launches, demand more resources than the average. Amplified compute resources empower websites to manage elevated traffic levels, maintaining peak performance by addressing each request promptly. Having room for such growth is crucial when actively driving traffic to your website. 

Uptime monitoring ensures your website stays accessible 

Website uptime refers to the availability of a website or web service within a given timeframe. This is represented as a ratio of the time available compared to the total time, often calculated monthly or yearly. 

Uptime monitoring tracks how often a website is accessible. It matters because consistent access ensures good user experiences. If a site frequently goes down, it can harm user engagement and reputation. Monitoring helps catch issues early for swift resolution. 

At Bluehost, we prioritize adhering to industry-standard uptime for websites. Our approach involves integrating advanced caching mechanisms, conducting thorough load testing, and providing responsive support. We also ensure uptime by implementing robust server infrastructure and redundant systems as well as closely monitoring our network to catch any potential issues early, allowing us to take swift action. Our data centers are equipped with advanced technology to minimize downtime risks, ensuring that your website remains accessible and operational for your visitors. 

We monitor our farm 24/7, ensuring a minimum of 99.9% uptime (with an aim of 99.95% soon). Moreover, we implement a ‘rebootless kernel‘ strategy to ensure critical security updates for the operating system do not lead to downtime. 

This strong focus on uptime reflects the reliability of our platform. Our infrastructure meets the highest industry benchmarks, ensuring that the website remains accessible and available to your audience as per industry best practices.
