Auto-scaling servers are a cloud computing function that modifies the number of server instances in response to real-time demand.  Servers are added or withdrawn here to keep your application and website running smoothly and available while optimising resource usage and costs.

Do you want to know how to handle traffic surges?  If so, the answer is auto-scaling servers.  With auto-scaling servers, new server instances are introduced when traffic loads increase, and extra server instances are withdrawn when traffic loads decrease, thereby reducing expenses.

This dynamic adjustment of capacity ensures that your application and website can efficiently and automatically handle unexpected spikes in traffic. In fact, it is because of this functionality that elastic hosting and scalable cloud servers have become a necessity for all businesses.

In this article, we will help you understand how auto-scaling servers work and the benefits of using them.

How Auto-Scaling Servers Work?

To detect changes in your website and application traffic, match the demand, and take appropriate actions, these servers rely on several key components. These are:

Monitoring

Autoscaling systems continuously monitor multiple metrics of your server or application. These metrics include CPU usage, network traffic, memory load, application response times, and request rates. It is with the help of these metrics that elastic hosting scalable cloud servers would know when it is time to scale their resources.

Scaling Policies

When it comes to using auto-scaling servers, scaling policies play an important role. This is because these policies will define how and when the resources should scale. These policies can be set based on:

  • Performance levels, if the CPU is used over 70%
  • Scheduled time windows, for example, weekdays between 9 am and 6 pm

The benefit of these policies is that they will keep your scaling processes aligned with the demand.

Scaling Actions

When using auto-scaling servers, you must use triggers that are activated, causing the system to perform the required scaling actions. These actions can range from launching new instances to modifying capacity or stopping idle servers.

Pro Tip: Choose a server provider with an Australian data centre, a 1 Gbps dedicated port speed, and RAID-10/RAID-6 hardware to get an Enterprise+ Server that can meet all your business needs. 

Load Balancing

This is one of those components that works hand in hand with auto-scaling servers, evenly distributing traffic across all available resources. The benefit of this approach is that it helps prevent bottlenecks while maintaining the steady performance of your website and application.

Cooldown Periods

The key to effectively dealing with traffic spikes is to avoid overreacting to them, using cooldown periods for help. These periods will help in preventing back-to-back scaling actions, thereby giving your system a chance to stabilise before making any further changes.

Health Checks

One of the key components of elastic hosting is scalable cloud servers, which include health checks that help maintain an accurate count of healthy instances. In fact, to keep the service quality, faulty instances are automatically replaced.

Benefits of Using Elastic Hosting Scalable Cloud Servers

The use of auto-scaling servers has become extremely important for eCommerce websites and applications, marketing campaigns, and other instances where workloads are variable, traffic patterns are predictable, but unpredictable traffic spikes are unavoidable.

There are numerous benefits to using elastic, scalable cloud servers. Some of them are:

Efficiently Handles Traffic Spikes

Auto-scaling servers react instantly to traffic spikes, keeping your website and application responsive even during peak hours. The smooth and stable user experience that you provide will help you retain customers and lead to more conversions as well.

Cost Effective

When using auto-scaling servers, you pay only for the resources you need. This is because this system shuts off idle servers during periods of lull, thereby helping you save money. However, when the requirement increases, they automatically increase the capacity, thereby saving you from poor performance and, consequently, loss of clients.

Reliable Performance

Considering that auto-scaling servers match the resources to demand in real-time, they can prevent overloading and crashing of your websites and applications. Thus, these systems enable the reliable performance of your apps and websites, thereby upholding your brand reputation and customer satisfaction.

Handle Traffic Surges With Auto-Scaling Servers

If you have an online business, you will likely experience sudden traffic surges for various reasons. Sometimes, it can be due to marketing efforts, and other times, it can be due to an organic traffic surge. Whatever the reason may be, the best way to deal with these changes in traffic in a cost-effective and performance-enhancing manner is through the usage of auto-scaling servers.
