Scalability and Elasticity in Cloud Computing – InfoQ


Cloud computing is a way to access software, storage, and other services over the internet. However, scalability and elasticity are two concepts that play a major role in the cloud computing industry. This article aims to explain these concepts in detail for anyone who needs them for their business or personal use.

Scalability and Elasticity in Cloud Computing – InfoQ


Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort.

Cloud computing allows organizations to quickly scale up or down as needed while paying only for what they use. It enables companies to focus on their core business instead of being tied down by infrastructure issues such as hardware acquisition and maintenance costs.

Cloud computing also provides greater flexibility in terms of scalability compared with traditional data centers because it allows you to add more resources when needed without purchasing additional equipment like servers or storage systems upfront; this makes cloud computing an attractive option for businesses looking at growth opportunities such as eCommerce sites or software startups launching new products/services into marketplaces where demand may fluctuate greatly over time

Types of Cloud Computing

  • Software as a Service (SaaS). This type of cloud computing is used to deploy applications and services. It’s a pay-per-use model, where you only pay for what you use. SaaS providers provide an interface that allows users to access their applications remotely through the Internet. The most common example of SaaS is Salesforce, which offers CRM (Customer Relationship Management) solutions to businesses around the world.
  • Platform as a Service (PaaS). PaaS provides developers with tools and infrastructure so they can build their own apps without worrying about anything else except writing code that solves specific problems within an organization or industry vertical like healthcare or financial services etc., instead of building everything from scratch themselves including servers etc., which would cost much more than using PaaS solutions from established providers such as Oracle Cloud Service or Microsoft Azure Cloud Platform because these companies already have invested heavily into developing these platforms so there’s no need for them anymore since now everyone can use them at affordable prices without having any technical expertise required!

Difference Between Elasticity and Scalability

Elasticity is the ability of a system to scale up and down in response to demand. This could be done by adding more resources, such as CPU power or memory capacity, or by increasing the performance of existing resources (for example, by optimizing software).

Scalability refers to increasing the performance of a system by adding more resources; it does not necessarily involve creating any new functionality in response to increased load on existing infrastructure

Scalability in Cloud Computing

Scalability refers to the ability to increase or decrease the size of a cloud application to meet the needs of the business.

If you need more capacity, you can scale up. If not, then you can scale down. Scalability allows businesses to quickly adapt their resources based on demand and usage patterns so that they don’t have to worry about buying too much or too little at any given time.

Elasticity in Cloud Computing

Elasticity is the ability of a cloud provider to scale up or down based on demand. It can be achieved through the use of virtual machines, containers, or serverless functions.

Cloud elasticity is built into its infrastructure and software stacks by design so that it can respond quickly to changes in workloads from different customers or applications running on top of that same platform. In order for this capability to work properly for you as an end user though there needs to be some level of standardization among all those different workloads so they can be managed as part of one big pool rather than individually (which would defeat the purpose).

Elasticity is the ability to increase or decrease the number of resources in response to changes in demand. It is often confused with scalability, but these terms are not synonymous; while both are related, there are significant differences between them.

Scalability refers to an application’s ability to handle increased workloads by adding more resources (such as additional servers). This can be done automatically without manual intervention from system administrators or developers; this makes it easier for companies to scale their services without having to worry about hiring additional staff members just for managing servers during peak usage periods (or worse yet – paying someone else).


The cloud computing industry has grown rapidly over the past few years, and this trend is expected to continue in the future. As more companies become aware of the benefits of using cloud services and start adopting them, there will be increasing demand for scalable solutions which can handle large amounts of data and traffic from multiple users at once.
