Engineering reliability at scale: Why developer-led agencies trust Kinsta for mission-critical projects

If you run a million-dollar e-commerce business or a high-traffic publishing site, and your hosting is only “good enough,” it’s time to switch providers.

There are several reasons why generalist, shared, or VPS hosting solutions consistently fail when it comes to high-volume websites:

• General hosting is not configured or optimized to support the complexities of WooCommerce or membership sites. Optimizing large databases, excluding specific cookies from the cache, and other essential optimizations for strategic sites are not typical of general hosting. On the other hand, managed hosting ensures your site operates smoothly and without downtime, even during traffic surges.
• A shared architecture can fail due to the proximity of “noisy neighbors” who absorb resources and can infect your site with malware and other security issues. If a site hosted on the same server suffers a DDoS attack, it could also bring down your site. Additionally, shared hosting typically performs less efficiently than cloud solutions.
• DIY or VPS hosting is inadequate because it requires a team of engineers to patch kernels, optimize caches, configure firewalls, and manage backups. These activities increase operational complexity, diverting time and resources away from developing new projects and features for clients.

Kinsta’s managed hosting for WordPress is different because it provides developers with all the necessary tools, including SSH, WP-CLI, Git integration, APM tools, and the Kinsta API, while offering a managed infrastructure that eliminates the workload associated with managing and maintaining the system and your WordPress websites.

With Kinsta, you have the freedom to create new projects and grow without worrying about managing the server or responding to emergencies. Let’s find out how!

Architectural excellence: How Kinsta eliminates bottlenecks

Your hosting architecture is the foundation of your online business, whether it’s a WooCommerce store that generates millions of dollars in revenue each year or a membership site with huge databases of user data.

Unlike other companies, Kinsta doesn’t use generic cloud infrastructure; we use a cutting-edge cloud hosting platform with a global distribution of data centers. Our machines offer superior computing power and accelerated memory throughput. This translates into lightning-fast processing of complex PHP requests and drastically reduced Time-To-First-Byte (TTFB).

Building on this cutting-edge architecture, Kinsta has developed a containerized hosting solution that ensures complete resource isolation between sites, including your own. Because there is no resource sharing, if another site on the same physical machine receives an overwhelming number of requests (legitimate or otherwise) or experiences a security breach, your site will not be affected.

Another feature that sets Kinsta hosting apart from traditional hosting is its native integration with Cloudflare, a content delivery network (CDN) with 300+ global points of presence (PoPs). Every new WordPress site launched on our platform automatically benefits from Cloudflare’s enterprise-level CDN, which boosts your site’s performance and provides a security shield.

A global CDN delivers static resources stored in the CDN cache from the location closest to your customers or visitors. This reduces the load on the origin server, shortens page load times, and reduces server bandwidth consumption.

Thanks to our Cloudflare integration, Kinsta customers also benefit from Edge Caching technology. This technology offers increased speed, performance, and greater scalability for large projects, as it shifts most of the load from the origin server to Cloudflare’s edge servers. Unlike traditional CDNs, which only cache static assets, Kinsta’s Edge Caching technology can cache an entire page’s HTML. The first request is intercepted by the nearest Cloudflare network node. If the page is not cached, the node requests it from the origin server. Subsequent requests, even from other users, are served directly from the edge node without routing the request to the origin server. This reduces Time to First Byte (TTFB) by up to 80% because the server doesn’t have to generate the page via PHP.

Cloudflare integration brings additional benefits, including automatic image optimization in WebP format, early hints technology, wildcard SSL support, HTTP/3 support, and a Kinsta-exclusive range of IP addresses.

Performance under pressure: How Kinsta handles going viral

There are times when your website’s performance is put to the test. A traffic surge from a viral post, influencer marketing campaign, or Black Friday can result in marketing success or a technical disaster. The outcome largely depends on the hosting infrastructure supporting your website.

Scalability

Kinsta ensures service continuity whenever your site experiences a traffic spike. Unlike traditional VPS or rigid cloud hosting, your site never goes down when it experiences a surge in traffic because our infrastructure absorbs the spike. Your site never goes down, and at the end of the billing period, you are charged an overage fee for the extra resources used.

This model enables the agency to keep the client’s website up and running while allowing for cool-headed discussions about upgrading the plan once the crisis has passed. In effect, it is an insurance policy against downtime.

Troy Benjamin, the founder of Blak Brews, shares their experience:

Five hundred visitors for the entire hour on the site, all at the same time. With Kinsta, we were able to handle that, piece of cake. We didn’t even sweat! People were able to add to their cart and then check out – there was no wait time. It loaded as if there was only one person on the site. It just empowered us.

In terms of costs, it’s worth mentioning that with the new bandwidth-based plans, site owners can choose the plan that best suits their site’s needs. They can choose between plans based on the number of visits or bandwidth.

If your site receives millions of visits, but the bytes exchanged with each request are limited, it would be better to choose a bandwidth-based plan rather than a plan based on the number of monthly visits. Depending on your site’s characteristics, this could ensure more efficient use of your hosting service and help you avoid overage fees in the event of traffic spikes.

Database optimization

Dynamic pages cannot be stored in the cache when a user is logged in. Each user action (e.g., purchase, course registration, comment) generates new queries on the database. Therefore, it is crucial to optimize the database to handle a high volume of concurrent connections.

An optimized database is essential for ensuring site speed, performance, and a smooth, flowless user experience. It allows the server to execute queries more quickly and efficiently because it requires less effort than an unoptimized database.

Kinsta’s automatic database optimization routine runs 24/7, relieving you of the need to use optimization plugins or execute complex queries manually. The routine optimizes critical parameters of your WordPress database and adjusts settings to maximize efficiency.

PHP optimizations

Our customers can select the PHP version for their site from the officially supported versions, as well as two additional versions that have reached the end of their lifecycle. This ensures theme and plugin compatibility, eliminating the need for urgent resolution of incompatibilities between the core, themes, and plugins.

Kinsta uses Opcache to avoid parsing and compiling PHP files with every request. The first time a file is executed, Opcache saves the compilation result (opcode) in RAM. On subsequent visits, the server skips the parsing phase and directly reads the ready code from memory. In short, OPcache reduces server response time (TTFB), lightens the CPU load, and improves the performance of heavy sites such as WooCommerce and membership sites.

Kinsta also provides a PHP performance add-on for projects that require more PHP memory. This add-on allows you to increase your overall PHP memory pool, the number of threads, and the PHP memory limit.

You can also modify PHP performance from MyKinsta under WordPress sites > sitename > PHP performance.

Application Performance Monitoring (APM)

An Application Performance Monitoring (APM) tool allows you to track the execution times of PHP processes, database queries, plugins, and scripts on a WordPress site. Tools such as Blackfire or New Relic allow developers to easily identify performance bottlenecks and optimize their WordPress site for speed and performance.

In addition to supporting third-party APM tools, such as Blackfire and New Relic, Kinsta provides all its customers with a free APM tool. Developed entirely in-house, Kinsta’s APM tool is available within the MyKinsta hosting dashboard.

Team administrators and developers can easily enable it from the MyKinsta dashboard by navigating to Sites > Site Name > APM. When you click Enable APM, you will be prompted to specify the monitoring time. We recommend enabling the APM tool only for the time strictly necessary to monitor performance, as it consumes resources and may slow your site while running.

After setting the monitoring time, the application starts recording all processes and database queries. At the end of the monitoring period, it provides all the collected data, which is sorted to allow for the immediate identification of any issues or bottlenecks.

Service continuity and security measures

In a mission-critical project, it is impossible to avoid all unpredictable events. This is why it is essential to have a hosting partner equipped with proactive, passive, and reactive security measures to ensure structural stability and the ability to promptly and effectively respond to unexpected problems.

Disaster recovery by design and redundancy

Recovery Point Objective (RPO) is “the maximum acceptable interval during which transactional data is lost from an IT service.”

To minimize RPO, Kinsta offers automatic daily backups, machine-level snapshots, and hourly and six-hour backup add-ons. These features ensure that, in the event of human error, failure, or breach, data loss will be minimal or nonexistent.

Each backup is stored on the same machine as your site and is a complete snapshot of your environment’s files, database, redirects, Nginx configuration, and MyKinsta settings.

Depending on your plan, backups are stored for either 14 or 30 days and can be restored with a single click.

In addition to daily and hourly backups, Kinsta creates a backup before specific actions, such as a search-and-replace in the database or a push from staging to production. These backups enable you to recover the last working version of your site in case any issues arise during critical operations.

Redundancy is another key feature of a hosting service that enhances the security of WordPress sites. Kinsta offers downloadable backups that can be stored locally, as well as an add-on that automatically stores backups in the cloud using services such as AWS or Google Cloud Storage. With these two options, you can have a backup of your backups stored either in the cloud or offline on physical devices, providing an additional layer of security.

Self-Healing infrastructure

Some anomalies require a system administrator. One such issue is a PHP engine crash. Kinsta solves this problem at its root: our infrastructure automatically detects when the PHP engine stops working and attempts to restart it. If our automatic attempts fail, you can easily restart the PHP engine from the MyKinsta dashboard with a single click.

Kinsta automatically optimizes your database. Our system automatically adjusts your MySQL database settings to meet the needs of your WordPress site, thereby improving MariaDB performance. If the automated process detects an issue that it cannot resolve, it notifies our team of sysadmins.

But there’s more. We check the status of all the WordPress sites hosted on our platform every three minutes. That’s 480 checks for each of your sites every day! If the system detects an issue with your WordPress site, our engineers are immediately notified, and the issue is likely fixed before you even notice it.

DDoS protection and hack-fix guarantee

Kinsta has established a security perimeter around your site to protect it from external threats. Thanks to our native Cloudflare integration, your site is protected by an enterprise-grade firewall and built-in DDoS protection. As a consequence, our infrastructure can block malicious access before it reaches your site, thereby maintaining your site’s availability and performance during an attack.

If that weren’t enough, Kinsta offers a free malware hack-fix guarantee. If your site becomes infected, our engineers will resolve the issue at no additional cost. For an agency, this means never having to pay for emergency hours to remove malware.

Automation and Workflow: Give developers their time back

The greatest expense for an agency is not hosting, but rather the time developers spend on repetitive tasks, maintenance, and site management. Kinsta automates repetitive tasks, including software updates, backups, uptime monitoring, security checks, and more, eliminating this unproductive work time.

CI/CD integration

With Kinsta, you can seamlessly integrate your hosting with popular code repositories like GitHub, GitLab, and Bitbucket. With this integration, you can automatically deploy code changes to your Kinsta live or staging site whenever a new commit is pushed to the designated branch, reducing the time needed for corrections and the release of new features, as well as the risk of errors that could arise from manually transferring code.

Automated staging environments and push-to-live

Kinsta provides automated staging environments to speed up and streamline the provisioning of new projects. You can push these environments to production with a single click. Kinsta supports selective push, so you can transfer only files, only the database, specific files and folders, specific database tables, or everything.

Kinsta API

Kinsta provides developers with a powerful REST API, allowing teams to integrate their existing applications with Kinsta hosting.

Thanks to Kinsta’s numerous API endpoints, developers can perform a wide range of tasks. These include, but are not limited to, the following:

• Create a new WordPress site, clone an existing site, create an empty site, and delete a site.
• Create a new staging website, push a staging environment to live, and delete a staging environment.
• Clear the cache, restart, and update the PHP, and get a list of denied IP addresses.
• Change the PHP memory limit and number of PHP threads per environment.
• Change your site’s path.
• Get and update your redirect rules.
• Get your site’s SFTP/SSH status and enable or disable it.
• Get a list of your site’s plugins and themes and update them.
• Add or remove a domain.
• Clear the edge cache and CDN cache on your site.
• And much more.

Our customers integrate the Kinsta API with various tools, including communication and collaboration tools, reporting and business intelligence tools, ticketing systems and CRMs, automation and CI/CD platforms, project management systems, WP-CLI commands, and custom dashboards.

The Kinsta API is a powerful automation tool that streamlines workflows. It simplifies everything from provisioning new projects to updating themes and plugins in bulk to reporting to clients. The API also enables you to develop cross-platform processes for managing complex projects for major clients that can be scaled up.

The Kinsta API is the most appreciated REST API in the managed hosting industry, making Kinsta the ideal partner for the most demanding development teams.

Pete Brundle, Development Lead at Straight Out Digital (SOD), shares his experience:

The Kinsta API has enabled us to develop internal tools that automate crucial processes like site provisioning and perform bulk operations across our websites, saving us considerable time and effort. This would really just be how rarely we have any issues, considering the number of sites we currently manage.

WP-CLI and SSH access

WP-CLI and SSH are available by default on all Kinsta servers. You only need to SSH into your server and start using commands.

With WP-CLI and SSH, WordPress developers can quickly and easily perform manual and repetitive tasks. With WP-CLI, you can perform massive updates in seconds, search and replace in the database, manage users, reset passwords, and more.

SSH enables direct communication with the server. With SSH, you can synchronize entire folders in moments instead of uploading files via FTP. You can also unzip large zip files directly on the server and view server errors in real-time while browsing the site.

You can also use bash files to perform multiple operations with a single command. For example, you can update the core, clear the cache, and optimize the database across all customer sites simultaneously.

SAML SSO

Single sign-on (SSO) is a key component of today’s digital ecosystem. It enhances security, improves the user experience, boosts productivity, and lowers operating costs.

MyKinsta supports the SAML SSO protocol to enable the secure exchange of authentication and authorization data between an Identity Provider (IdP) and a Service Provider SP. This powerful feature enables agencies to eliminate the hassle of manual access management, streamlining the entire onboarding, user management, and offboarding process.

Kinsta also supports just-in-time (JIT) provisioning, allowing you to automatically create a new MyKinsta account when a user logs in for the first time via SAML SSO. JIT provisioning speeds up and improves the effectiveness of both user onboarding and offboarding, while increasing overall system security and reducing the workload and responsibilities for sysadmins.

Why Kinsta is the best choice for developer teams

To understand the strategic value of a hosting partner, don’t focus solely on technology; consider the economic and operational value of the hosting service for your agency or team. This perspective will make clear why hosting is a strategic asset rather than an operating cost.

Total Cost of Ownership (TCO): Calculating the savings of “Managed DevOps”

Many agencies that opt for the DIY or VPS option only calculate the visible costs, such as the monthly hosting fee. However, they overlook the hidden cost of the labor hours required to manage an unmanaged infrastructure. These tasks require a DevOps engineer or senior SysAdmin to handle security patches, kernel updates, stack optimization, and more. The cost can be very high.

Kinsta solves this problem at its root by automating these tasks almost entirely.

When choosing an unmanaged hosting solution, you need to purchase and configure additional services and tools. These may include an advanced backup system, an enterprise-grade firewall with DDoS protection, a high-quality content delivery network (CDN), staging environments with selective deployment, uptime monitoring tools, and robust security controls.

At Kinsta, these costs are all zero because these tools and services are included with all our standard plans.

Here’s what Sepas Seraj, CEO and founder at Pixeled Eggs, has to say about Kinsta:

The hassle-free solution and time we’ve saved in our development team have been a major return on investment. It means we can focus on what we do best, which is designing and developing high-performing WordPress sites for purpose-driven clients.
