KartHost has been hosting websites since the year 2000. We have always looked for the best of hosting platforms since we have been in business. We have added the proprietary Convesio stack to our offering and come to appreciate that these combinations of technologies both proprietary and open source are the next-generation platform for hosting WordPress sites. One we are excited about!
Unlike traditional WordPress hosting solutions, the Convesio platform addresses limitations in shared and VPS hosting by providing a multi-tenant, redundant environment powered by Docker Containers. Each site running on the platform is backed by a redundant file system, database cluster, scalable PHP Runtime, and self-healing architecture.
We believe you will be as excited as we are when your site is operating on this new state of the art platform.
KartHost has been involved in beta testing the platform since early 2019.
With Caching enabled a single container site has been tested with 2000 concurrent users over a 2 hour period with 8.8M requests being served and a sustained Requests Per Second of over 1400 with an error rate of 0.065%.
Important Note: This was an un-throttled test that was designed to push the limits of a single container site and not to be considered the capacity of our $16/month/site price. The North American cluster is handling over 70 million requests per month as of March 2019.
The majority of Shared hosting providers typically use many off the shelf products to offer a very generic hosting solution designed for a wide array of websites (WordPress, Drupal, Joomla, Shopping Carts, Custom Apps and more). In fact, KartHost cPanel Hosting uses the same technology except we do not overload our dedicated cPanel.
However, our WordPress Advanced VPS Container hosting is 100% focused on hosting WordPress. Our Advanced VPS Container hosting was designed specifically for WordPress. We do not support any other content management systems or custom code outside of the WordPress framework of Themes and Plugins on the Advanced VPS Container platform, thus the name WordPress Advanced VPS Container hosting.
The KartHost Advanced Managed VPS platform for WordPress is totally different than what standard web hosting providers. We provide all the important tools to allow experienced WordPress users to manage their hosting like SFTP, phpMyAdmin, and implementation of PHP, Percona, GlusterFS, and other components to make sure your WordPress site is running at a high-performance level.
We use "best in class" servers. So KartHost Advanced Managed VPS for WordPress hosting is Datacenter agnostic. We can deploy on bare metal servers and cloud providers such as Amazon. While Amazon is the current provider of the web servers, Google Cloud, and coming in the future Digital Ocean.
We provide you to choose from the United States (default), the United Kingdom, and Australia.
If you are planning a business that is targeting anywhere in those markets (regardless of where you are based) it will help with "local" SEO in those countries.
Coming later in 2020, we plan on server locations in South America, South Africa, European Union, and more as needed.
Should you have a large number of websites and would like dedicated hardware, we do offer a private cloud version of this platform which will allow you to have a dedicated cluster in your region of choice. Contact us for details.
While yes! A website can run in one single PHP Runtime container or multiple containers. There are a fixed number of PHP Workers and vCPU's in each container.
If you have a processor intense WordPress website (example eCommerce, social site, News site, Membership site etc.) and have a large number of visitors you will for sure want to run your website in multiple containers from the onset.
We are sorry to say at the moment, no. However, as we roll out this platform we will be adding Multisite in the future.
There are many WordPress hosting providers using containers, but using containers is only a small part of the story. KartHost containers in a much different way. Our competitors are using containers as the next generation VPS. All the components run in a scalable container. This creates an environment similar to a traditional VPS with all the same normal Single Points of Failure associated with WordPress.
KartHost has a container-based architecture that is scalable at several different layers. For example, your WordPress runtime, which is just your PHP Instance, can scale separately from your DB Instance and our Load Balancers. When your WordPress website starts to get a large amount of traffic or is becoming compute-intensive these other container-based systems can scale up your resources increasing RAM, CPU, etc to handle the load.
The difference is the KartHost Advanced Managed VPS Container system architecture uses a scale-out process to replicate your site running in multiple containers. And these multiple containers are attached to a multi-node Percona XtraDB Cluster. This is advantageous because the platform we have gives us the ability to run your site on multiple servers simultaneously, which greatly increases redundancy and scaling capacity.
And we can give this to you at affordable pricing!
No 3rd party caching plugin is needed!
KartHost using Convesio semi-proprietary caching implementation featuring 3 distinct layers of caching.
 Layer 1 (L1) of the caching resides at our load balancer layer.
 Layer 2 (L2) uses NGINX micro caching.
 Layer 3 (L3) runs inside each container with the PHP runtime of the site and utilizes Varnish.
And L1 decides what will be stored on L2 and L3. Based on how many requests an asset receives and the number of times it has been modified during those requests.
Intelligent Caching is enabled by this implementation that is aware of content changes at the container level and distributes load to optimize performance.
*L1 and L2 are in production and L3 scheduled for release in the near future.
