What is Cloud Scalability?

Cloud scalability is increasing your cloud servers’ available storage, memory, and processing power to meet your growing needs.

With cloud servers, you purchase and operate a “virtual machine” that uses resources from a third party’s physical server bank. You scale your cloud server by adding a new “virtual machine” or memory, storage, or processing power to your existing one.

Cloud computing makes scaling easier because your third-party provider already operates a vast server bank. This existing infrastructure means you can quickly and easily add new resources to your virtual system.

The difference between cloud scaling and scaling your physical infrastructure is that the latter requires purchasing, installing, and operating a new physical server. With cloud scaling, your provider already has the necessary resources, allowing you to use them with the click of a button.

Types of Scaling in Cloud Computing

There’s more than one way to scale in cloud computing. The three most common types of scaling in cloud computing are vertical, horizontal, and diagonal. We cover these three types of scaling in cloud computing below:

Vertical Scaling

Vertical scaling is when you add memory, storage, or processing power to your cloud server. You do this by using a higher percentage of your machine’s existing resources or upgrading parts of that server to increase its overall capacity.

Vertical scaling is effortless with cloud computing. You already have a virtual machine configured, and adding more processing power simply requires more capacity. You can often set this up to happen automatically as demands on your virtual machine grow.

The alternative way to achieve vertical scaling is to swap out parts in existing servers to increase their performance capacity. This is not an option with cloud computing because users cannot access the physical server(s).

The downside of vertical scaling is that it can impose an upper limit on the server’s maximum storage, memory, and processing power.

Horizontal Scaling

Horizontal scaling is when you add more servers to your cloud ecosystem to spread the workload across multiple machines. In cloud computing, you can scale horizontally by adding more virtual machines, or “instances,” to your setup.

The advantage of horizontal scaling is better performance. You avoid using any server near its total capacity, which means faster processing. It also means you have more headroom for short-term increases in server traffic.

The disadvantage of horizontal scaling is that it takes up more resources and is often complicated to implement. Each new server must be configured separately to be part of the server cluster. Usually, you have to manage each server individually regarding security and updates.

Diagonal Scaling

Diagonal scaling is a hybrid model that borrows vertical and horizontal cloud scaling elements. Adding more virtual machines while increasing each device’s capacity offers you a mix of the benefits of either approach.

The Difference Between Cloud Scalability and Cloud Elasticity

The difference between cloud scalability and cloud elasticity is a server’s ability to adapt to short-term changes in demand. In contrast, cloud scalability is its ability to keep up with long-term growth in the market.

Elastic cloud infrastructure can expand or shrink its capacity to meet short-term fluctuations in usage. Businesses with variable and unpredictable needs may see cloud infrastructure elasticity as an effective solution to keep up with spikes in demand without needing to pay to constantly maintain a higher volume of server resources at all times.

Scalable cloud infrastructure can expand to meet the planned growth in demand that comes with the expansion of your project. Cloud scalability is all about building infrastructure that can support your business long-term.

Is Cloud Really Scalable?

Yes, the cloud is scalable. Small to medium-sized businesses can expand their infrastructure by using cloud-based servers. There is an upper limit to your third-party provider’s total server capacity. Even Amazon Web Services (AWS) doesn’t have infinite server storage, processing power, and memory.

Benefits of Cloud Scalability

There are five key benefits of cloud scalability.

  • Convenience: Cloud infrastructure allows administrators to add new capacity with just a few clicks. Sometimes, you can pre-configure your servers to automatically scale as you introduce additional processing capacity for your apps.
  • Flexibility and Speed: Cloud scalability allows you to plan for business expansion without worrying about resource restrictions. In addition to this flexibility, the process of scaling servers is a matter of minutes.
  • Cost Savings: Physical infrastructure is expensive, and a business with reasonable traffic needs a lot of capacity to meet the demand. Scalability in cloud computing helps deal with temporary traffic spikes and planned service increases without a permanent increase in hosting expenses.
  • Disaster Recovery: Storing data on a server comes with the risk that a technical failure or natural disaster could destroy your data. Scalability in cloud computing allows you to add dedicated storage options for storing additional copies of your data at a fraction of the cost of adding a new server.
  • Reliability: With scalable servers comes better website or database performance. You also have the confidence of knowing that redundancy in infrastructure ensures failover for sustained performance even if one node goes down.

When to Consider Cloud Scalability

Scaling your cloud infrastructure is a crucial decision because of its impact on business revenue and growth. Here’re some scenarios where you should give it serious thought.

  • When your business is growing: A growing business has rapidly expanding data storage and processing needs. This is a great time to partner with a reliable third-party provider to facilitate this expansion.
  • When growth is unpredictable: If you experience peaks and troughs in your user demands, you can start with an elastic cloud server solution to deal with the situation. At the same time, you collect trend data to make the scalability decision later down the road.

Alternatives to Cloud Scalability

Cloud computing isn’t the only way to scale your business operations. Here are a few options you could consider instead of scalability in cloud computing setups.

  • Edge Computing: With an edge computing setup, some data is processed at the source, either at the front end or at the collection point. An example of edge computing would be an intelligent thermostat adjusting heating settings. This reduces the amount of data that must be sent to a centralized server in the cloud.
  • Fog Computing: Fog computing is an intermediary step between edge and cloud computing. Here, a local network decides to access local data sources and communicates with a centralized cloud database. To scale with edge computing, you would send only selected raw data to the central cloud and process more data and decisions within the local networks.
  • In-House Servers: You could also scale your infrastructure by installing and operating servers on-site. This arrangement gives you more control over security and internal protocols. However, in-house servers require an in-house technical team and a dedicated budget for operations.
  • Bare-Metal Servers: These servers are a great alternative to scalability in cloud computing solutions. Bare-metal server solutions involve dedicated physical servers hosted at external data centers. These servers have several benefits, such as tiger security and scalable server resources, without spending on server infrastructure and maintenance.
