Vertical Scaling vs Horizontal Scaling

3 May 2023 by Bare Metal

As the amount of data businesses generate continues to grow exponentially, business owners must make decisions as to how they use and store that data. Two options are horizontal scaling and vertical scaling – both of which have their benefits in specific situations.  

To ensure successful storage and maintenance, it is important for business owners to understand the differences between these two methods of scaling in order to make an informed decision on which one fits their current environment better.  

Bare metal solutions play a crucial role in helping businesses achieve their scaling goals, whether it involves vertical or horizontal expansion. Vertical scaling, which refers to adding more capacity to an existing system, can be accomplished through the use of bare metal servers that offer high processing power and memory capacity.  

On the other hand, horizontal scaling, which involves adding more systems to a network, can be achieved by leveraging the hardware resources of bare metal solutions. Bare metal solutions let businesses change their infrastructure quickly and easily. This helps them become more successful in today's competitive market, no matter how much they grow. 

In this blog post, we will examine what horizontal versus vertical scaling is before exploring when each option might be best used by businesses today. 

Horizontal Scaling vs Vertical Scaling 

Horizontal and vertical scaling are two different approaches to adding resources to an IT system. Horizontal scaling involves adding more machines to distribute the load of an application. This can be done either by adding more servers or by setting up a cluster of machines.  

On the other hand, vertical scaling is the process of adding more resources to an existing machine, such as increasing the memory, storage, or processing power. Horizontal scaling is typically done to improve availability and redundancy, while vertical scaling is used to improve the overall capacity and performance of a system.  

Both horizontal and vertical scaling strategies have their own advantages and disadvantages, and which one to choose depends on the specific needs and constraints of the system. 

Benefits of Horizontal Scaling 

Horizontal scaling has numerous benefits for businesses. By distributing the load of an application across more machines, horizontal scaling provides increased availability and redundancy for an IT system. This means that even if one machine fails or experiences issues, the overall performance of the application is not affected.  

Horizontal scaling also allows businesses to easily accommodate increases in traffic and demand without the need for costly upgrades to individual machines. Additionally, horizontal scaling can help to reduce downtime during maintenance and updates, as it allows for the seamless switch of traffic onto other machines within a cluster.  

All of these benefits combine to improve overall system performance, ensuring that businesses can meet their customers' needs in a reliable and efficient manner. Horizontal scaling is an effective approach when businesses need to increase their capacity to handle unexpected surges in traffic, maintain resilient systems, or accommodate growing user bases.  

For instance, e-commerce websites that experience sudden sales spikes during holidays can use horizontal scaling to ensure a seamless customer experience. Streaming media services need to be able to handle more users and bigger requests for streaming. To do this, they use something called horizontal scaling. 

Organizations like banks and laboratories that need to quickly work with lots of data can use horizontal scaling. This means they spread the work out on multiple servers. Horizontal scaling is a great way to help businesses grow quickly and make sure their important applications keep working when demand increases. 

Benefits of Vertical Scaling 

Vertical scaling provides numerous benefits for businesses. By adding more resources to an existing machine, vertical scaling allows for a significant increase in the overall capacity and performance of an IT system. This means that a business can handle larger workloads and support more users without the need for additional machines.  

Additionally, vertical scaling can be a more cost-effective solution in certain cases, as it allows for the full use of existing hardware before purchasing new machines. This approach can also be less complex and easier to manage, as there are fewer machines to maintain and monitor.  

Vertical scaling can be beneficial for organizations that have significant data processing requirements or intensive workloads. For example, financial institutions that deal with high-frequency trading often have demanding processing requirements and may need to vertically scale their infrastructure to ensure fast and reliable transaction processing.  

Also, databases that require significant storage and memory, such as those used for scientific or research purposes, can benefit from vertical scaling. Overall, vertical scaling is best utilized when a business needs to enhance the performance of a single application or server that is underperforming. 

No Cost Consultations 

It's important for businesses to make informed decisions when it comes to how they use and store their data. With careful consideration, companies can utilize horizontal and vertical scaling strategies to maintain the health of their systems at all times.  

Horizontal scaling involves adding more nodes to the resource pool, whereas with vertical scaling, components of an existing server are upgraded or replaced with a better configured device. Consider performance needs, size of current instances, flexibility, upgrade regularity, scalability cap, redundancy and geographical distribution when choosing between the two scaling models.
