Can you suggest a reliable hosting provider for a high-traffic project? Our current hosting provider has 30 cores, 16 GB RAM, and SSD hardware, but internal interruptions are hindering our work.

To save costs during times of high server load, it is more cost-effective to simply use multiple servers rather than attempt to fix the issue. It is ideal to have two or three servers that are equally capable.

There are various benefits to having multiple servers. One benefit is the ability to distribute server load, which allows for better performance and uptime. Additionally, if one server fails, the other servers can continue to function, ensuring continuity of service.

Typically, for these types of projects, it's recommended to utilize BIG DATA servers. In my experience, I've found that Unihost's server line is a solid option. These servers boast impressive uptime rates and are located in a standard data center situated in France (OVH) with reliable support services.
Each server is equipped with DDoS protection up to L7 level and provides 500GB of free backup storage (with the option to purchase additional NAS storage). The feature that stands out the most, however, is the ability to create a virtual network by connecting servers located in different racks. As for traffic, it's unlimited, and the uplink is 1 Gbps with a guaranteed bandwidth of 500 Mbps.

WSR is a great addition to hosting that I highly recommend. By utilizing their CDN's caching dynamics, the load reduction will be significant since pages are no longer generated constantly by the CMS. Additionally, the firewall filters out unnecessary requests, which also contributes to its positive effects.

Caching is an effective way to reduce server load and speed up website loading times. It's important to consider all possible options when it comes to reducing server load, and WSR is one such option that can make a significant impact. The combination of caching and firewall filtering brings about a more optimized web experience for users.

There are numerous hosting providers that can handle high-traffic needs, particularly dedicated and cloud-based hosts. Remember that good hosting isn't just about server specifications; it also involves factors like uptime guarantee, support quality, network capacity, and added services like content delivery networks (CDN), DNS, and DDoS protection.

Here are a few reliable options for high-traffic projects:

Amazon Web Services (AWS): They offer flexible and scalable hosting solutions. They have highly scalable services like EC2 for compute, S3 for storage, and many others like RDS for managed databases.

Google Cloud Platform (GCP): Much like AWS, GCP offers a myriad of services. Its compute engine can be configured to suit your needs. It's particularly strong in data-related and machine learning services, if those are relevant to your project.

It's also worth noting that you might want to enlist the help of a database administrator or systems engineer (if you don't already have one on your team) to ensure you have a robust database system and server setup. High-traffic websites often have to worry about database optimization as much as server power.

As mentioned previously, for high-traffic projects, consider looking into robust solutions to address specific aspects such as load balancing, efficient content delivery, traffic spikes management, data redundancy, continuous backups, DDoS protection, and DNS management.

There are several reliable hosting solutions available for high-load websites that can handle increased traffic and ensure optimal performance. Here are a few options:

Dedicated server hosting: With dedicated hosting, you have an entire server dedicated to your website, providing high performance and robust resources. This is an excellent choice for websites with heavy traffic and resource-intensive applications.

Cloud hosting: Cloud hosting offers scalability and flexibility, allowing you to easily handle high load situations. With cloud hosting, your website is hosted on a network of interconnected servers, and resources can be allocated as needed.

Content Delivery Network (CDN): CDN services can improve the speed and performance of your website by caching your content on servers located across different geographical regions. This ensures that users can access your site quickly regardless of their location, reducing load times and handling high traffic effectively.

Load balancing: Load balancing distributes incoming traffic across multiple servers, preventing any single server from becoming overwhelmed. This ensures that your website can handle high-load situations by evenly distributing the resources.

It's important to evaluate your specific needs and consult with hosting providers to choose the solution that best suits your website's requirements and budget.
