Hardware stack

Kinsta utilizes virtual machines in one of Google Cloud Platform’s multiple data centers. Each machine has up to 96 CPUs and hundreds of gigabytes of RAM. Hardware resources (RAM/CPU) are allocated to each site container automatically by our virtual machines on an as-needed basis.

Everything is interconnected over the highly reliable Google Cloud Platform’s “premium tier” network. This is designed to minimize distance and hops, resulting in faster more secure global transport of your data. Some hosting providers might opt for Google’s “standard tier” network service to cut costs, but we believe in only utilizing the best here at Kinsta.

Software stack

Kinsta utilizes LXD managed hosts and orchestrated LXC software containers for each site. What this means is that every WordPress site is housed in its own isolated container, which has all of the software resources required to run it (Linux, Nginx, PHP, MySQL). The resources are 100% private and are not shared between anyone else or even your own sites.

MySQL databases are hosted at localhost, not a remote server. This ensures that there is no latency between machines, which results in faster queries and quicker page load times.

We have a unique solution that allows us to live migrate the LXC containers between the LXD managed host machines when needed, without your site incurring any downtime. This also allows us to take advantage of ZFS based snapshots of the whole containers, which can be taken instantly, without any server overhead.

Kinsta takes security very seriously, implementing active and passive measures to stop attacks and malicious intent in its tracks. We monitor your sites every minute for uptime, detect DDoS attacks as they happen and proactively stop malicious code from entering our network.

We automatically create 2 weeks worth of backups, meaning a hacked or defaced site can be instantly rolled back from within the MyKinsta dashboard. Automatic backups are taken on a daily basis, but you can increase the frequency in which these are taken by purchasing one of our addons. You could backup every 6 hours or even every hour. For high-traffic or dynamic sites, this can bring peace of mind knowing you roll back your site at a moment's notice without data loss.

Hardware firewalls are in place and have very tight software based restrictions. The bottom line is: your site is monitored and secured 24/7. But here are just a few additional ways we protect your site:

• You can enable two-factor authentication to protect your login.
• We automatically ban IPs that have more than 6 failed login attempts in a minute.
• Kinsta stands behind it’s hack-free guarantee. If a site is compromised while on our network, we’ll fix it for free.
• We only support encrypted SFTP and SSH connections (no FTP).
• Free Let's Encrypt certificates are one-click away in the MyKinsta dashboard.
• We enforce strong passwords on all new WordPress installs.
• WordPress minor security patches (not core) are automatically applied as soon as they are available to ensure your site is fully up to date.

Kinsta uses Google Cloud Platform’s multi-regional deployment mode. This means that you aren’t restricted to a single data center for your account, and can choose a different data center for each of your WordPress sites.

Google offers 18 locations throughout the USA, Europe, Asia-Pacific, and South America. They are strategically placed to offer the lowest latency anywhere in the world. This also results in blazing fast SFTP download and upload speeds.

Amazon Route 53 premium DNS is included for free for all Kinsta customers. Their global Anycast network, along with latency and geolocation routing help ensure your website is always online, stable, and has fast DNS lookup times.

We’ve also partnered up with KeyCDN, a real-time HTTP/2 and IPv6 powered content delivery network, with 34 POPs around the globe to speed up delivery of your assets (images, JS, CSS). Free bandwidth is included with every plan.

Combine the above with our optimized WordPress stack of PHP 7, Nginx, HTTP/2, and MariaDB; and you’ve got yourself a lightning fast solution that is ready to tackle any load.

Auto-scaling essentially means that our infrastructure is ready to handle your sudden surges in traffic and load. With our isolated software container technology, hardware resources are allocated to each site container automatically by our virtual machines on an as-needed basis. The result is a hosting configuration that is secure and private by design while simultaneously allowing server resources to scale up or down as needed based on the demands of the site.
