Rate Limiting Made Easy with Bare Metal IaaS

30 May 2023 by Datacenters.com Bare Metal

Rate limiting is one of the most powerful tools available to businesses for controlling usage and preventing abuse, but it can be a tricky concept to wrap your head around. Rate limiting ensures that all incoming requests are handled within some predetermined limit set by you or your IT team – making it easy to ensure an even user experience across your applications.  

Fortunately, with Bare Metal Infrastructure-as-a-Service (IaaS) solutions like those offered by our industry leading portfolio of global data centers, rate limiting of applications can be effortlessly achieved without having to undertake any intricate setup processes or manage advanced control panels.  

This blog post aims to give you an in-depth understanding of how rate limiting works and its capabilities so you can make educated decisions on how best to incorporate it into your own business systems and services.  

We will discuss what rate limiting is, the types of settings that are used, and the benefits that rate limiting offers. By examining each element closely, we hope you walk away feeling confident enough to determine whether or not incorporating rate limits into your infrastructure makes sense for your business.  

What is Rate Limiting?  

Rate limiting is a technique used by websites and applications to control the amount of traffic they receive. It works by setting limits on the number of requests that can be sent to a server within a given time period, usually measured in seconds or minutes.  

This helps to prevent users or bots from overwhelming the server with too many requests at once, which can cause the website or application to slow down or even crash. Essentially, rate limiting is like regulating the flow of traffic on a busy road, ensuring that everyone can get to their destination safely and without causing congestion.  

By controlling the volume of traffic, rate limiting helps to maintain the stability and performance of online services, and ultimately provides a better experience for users. Rate limiting is a valuable technique used not only to control traffic on websites and applications, but also to protect APIs from unintentional and malicious overuse.  

APIs (Application Programming Interfaces) are sets of standards and protocols used for building software applications, and are often used by developers to access data or functionality from third-party services. By setting limits on the number of requests that can be made to an API within a given time frame, rate limiting helps to prevent users or bots from overwhelming the service with too many requests at once.  

This helps to maintain the stability and performance of the API, and also protects against security threats such as denial-of-service attacks. Overall, rate limiting is an important tool for ensuring the reliability and security of APIs, and plays a vital role in protecting online services and data. 

Benefits of Rate Limiting 

Rate limiting is an important tool for maintaining the integrity and availability of online services, while also protecting against security threats, making it a valuable investment for businesses of all sizes. Rate limiting offers several business benefits, particularly for companies that rely on online services and applications.  

Server Overload 

By controlling traffic and preventing server overload, rate limiting helps to ensure the stability and reliability of online services, reducing the risk of downtime or service disruption. This can lead to increased customer satisfaction and loyalty, as users are able to access the services they need without experiencing frustrating delays or errors. 


Rate limiting helps to protect against security threats, such as DDoS attacks or brute-force login attempts, which can cause significant damage to a company's reputation and financial wellbeing. By mitigating these risks, rate limiting helps to safeguard sensitive data and protect valuable assets. 

Managing Costs 

Rate limiting is an effective way for businesses to manage costs related to online services and applications. By limiting the amount of traffic that can be sent to a server or API within a given time period, rate limiting helps to reduce the amount of resources needed to handle requests, which in turn reduces infrastructure costs. This can be particularly valuable for businesses that experience spikes in traffic or usage, as it allows them to scale their infrastructure more efficiently and avoid overprovisioning.  

Additionally, rate limiting helps to prevent abuse of online services, such as automated scraping or excessive API calls, which can lead to inflated costs and reduced efficiency. By controlling usage and traffic, rate limiting helps businesses to manage their costs more effectively, ensuring that they are getting the most value from their online services while keeping expenses under control. 

Simplify Rate Limiting with Bare Metal IaaS 

Bare metal deployments are an excellent choice for IT departments that need to implement rate limiting for their applications. With bare metal infrastructure, the resources of a dedicated server can be allocated solely to the application in question, avoiding the overhead and potential conflicts of virtualization.  

This allows for more precise control over resource allocation, making it easier to enforce limits on the number of requests an application can handle within a given time period. Additionally, bare metal deployments provide better security measures than virtualization, as they eliminate the risk of "noisy neighbor" attacks between different virtual machines on the same physical hardware.  

Overall, bare metal deployments allow for more efficient and secure implementation of rate limiting, making them an ideal option for IT departments. 

Rate Limiting Tips  

Administrators have the ability to set rate limits. These limits can be configured based on parameters like IP addresses, geographic regions, time intervals and usernames.  

To govern traffics effectively, these admins are provided with an array of algorithms such as token bucket, greedy token bucket, leaky bucket, fixed window, rolling window, and sliding log to better suit their needs. Thanks to these options distinct configurations can be created for improved performance management. 

Rate limiting can protect your system from malicious traffic. To achieve this goal, it can be implemented on either the server side or the client side. Strong rate limiting requires extensive testing to verify performance is optimally maintained. Accurately gauging a balance between convenience and security with rate limiting isn’t simple, so proper testing needs to be conducted to demonstrate that it truly functions correctly.  

Protecting your API against malicious threats is hugely important. A great way to do this is by implementing rate limiting. This method of defense may sound complicated, but in reality it's actually quite straightforward. It's one of those oddly simple solutions that can provide surprisingly powerful results, making it an invaluable tool in keeping your API secure and performing at a high level. 


In conclusion, rate limiting is an effective and important tool for businesses to control usage of their applications and maintain a secure user experience. It's essential that IT teams take the right steps when setting up these limits, as the consequences of misconfiguration can be severe. 

With the right infrastructure in place, however, rate limiting isn't something to worry about. Bare metal deployments provide a dedicated server environment for applications that require rate limiting and can help ensure maximum performance.
