What You Need to Know about Cloud Computing Elasticity

Table of contents

Cloud providers offer various services and resources that help organizations scale their operations. One of the benefits of cloud systems is their elasticity, which means you only pay for what you use, and your systems can handle workload demands smoothly. This makes cloud services cost-effective and highly adaptable to the ever-changing business needs. This article will explore the importance of elasticity in cloud computing.

Importance of Elasticity in Cloud Computing

When organizations move to the cloud, they no longer have to deal with the complexities and costs of maintaining legacy infrastructure or using outdated computing paradigms like grid computing. The elasticity of cloud computing is a significant advantage for organizations that choose to make the move, as it allows them to quickly scale resources up or down to match their business needs. By doing so, they can become more agile in their operations without paying for unused cloud capacity.

Key Concepts and Terminology

To efficiently leverage a cloud elasticity solution, you must first understand its key concepts. Read our glossary on elasticity in cloud computing.

Cloud Computing Elasticity – Definition

The elasticity of cloud computing can be compared to using a flexible rubber band that adjusts according to the needs of your computer resources. Put simply, cloud technology allows you to easily adjust your computer power, memory, and storage to suit the unique requirements of your application. This can be done either automatically based on demand or manually when required.

Elastic Cloud Computing Instance

Instances are like virtual servers in the cloud that can be easily adjusted in size. Their scalability allows organizations to manage resources and costs efficiently by changing their computing power as needed rather than paying for fixed server sizes.

Provisioning and De-provisioning

Provisioning is an act of adding resources to your system as and when demand grows. Conversely, de-provisioning is about resource removal when demand takes a dip. The goal is to keep resource allocation in sync with the ever-changing needs of your system, ensuring optimal efficiency.


Cloud elasticity enables organizations to expand resources using external cloud capacity when unpredictable workloads occur. Bursting is a flexible deployment approach that lets organizations tap into the scalability of a public cloud when their private cloud can’t handle the demand. This is like borrowing extra power from an external cloud, which is not only cost-effective but also spares you from getting locked into long-term infrastructure costs.

Elastic Load Balancing

This technique ensures that incoming network traffic is divided intelligently among various resources or servers. The aim? To make sure each of them carries its fair share of the load. This boosts performance and prevents any single resource from buckling under pressure.

Capacity Planning

Capacity planning is the process of estimating the amount of resources like computing power, instance storage space, and network bandwidth a system will need in the future based on historical usage patterns and growth expectations.

On-Demand vs. Reserved Instances

On-demand instances are like pay-as-you-go services, where you only pay for the resources you use when you use them. In contrast, reserved instances involve committing to a specific amount of resources for a fixed duration, often leading to cost savings but with less flexibility.

Resource Pooling

Cloud providers pool computing resources, networks, and storage to serve multiple clients simultaneously. They deftly allocate and reallocate resources based on consumer demand, ensuring everyone gets their fair share. Elasticity in cloud computing enables cloud providers to meet the various needs of many customers while remaining financially viable.

Cloud Elasticity vs. Scalability: Understanding the Difference

Many people use the two terms interchangeably, but understanding the difference between scalability and elasticity in cloud computing is essential. Cloud elasticity refers to the ability to quickly and temporarily adjust resources in response to sudden or seasonal changes in workload trends.

Meanwhile, cloud scalability focuses on managing the long-term growth of workloads, allowing organizations to handle anticipated increases in demand efficiently. In other words, cloud scalability is about planning for the future, while elasticity is about responding to the present.

In essence, the difference between elasticity and scalability in cloud computing is like the difference between building a solid foundation for a skyscraper, carefully planning and constructing it to support future floors, versus having a flexible set of modular rooms within that skyscraper that can be rearranged or expanded on short notice to accommodate various events.

Both scalability and elasticity for cloud computing are essential components of effective cloud management, which means that companies must balance the two to ensure cost-effectiveness and data and business continuity.

How Cloud Elasticity Works

If you encounter a sudden increase in workload, elastic computing can aid with operating system support. But how does elasticity in cloud computing actually work?

Dynamic Resource Allocation

Effective cloud computing relies on dynamic resource management and allocation. This process involves assigning and adjusting available resources to meet the changing demands of cloud applications. Doing so helps ensure that a cloud system operates efficiently and provides a seamless experience, regardless of the level of demand.

In this context, it’s essential to understand the concept of demand-based allocation (automatic scaling), whereby resources are added or removed on the fly as needed. For example, think of a website that gets a sudden traffic surge. It quickly adds servers to handle traffic spikes and scales down as required.

Real-time Demand Analysis

It is crucial to analyze the demand in real-time to achieve cloud elasticity. This analysis facilitates the dynamic adjustment of cloud resources based on the current demand, thus ensuring optimal resource utilization, quick adaptability, self-sustained operation, and the ability to handle unexpected spikes in demand.

Automated Scaling Mechanisms

Cloud computing enables automatic adjustment of server resources and virtual machines in response to traffic patterns or utilization levels, a feature known as auto-scaling. This means that when your workload increases, more instances can be added automatically, and when demand decreases, idle resources are removed.

Best Practices for Leveraging Elasticity of Cloud Computing

Now that we’ve established the difference between scalability and elasticity let’s explore how to maximize the use of elastic systems in cloud computing.

Monitoring and Metrics Collection

Collecting real-time metrics and monitoring resource usage allows for adjustments to different workloads and identifying inefficient resources – it’s like data analytics for your cloud.

Setting Elasticity Boundaries and Limits

Defining upper and lower limits for CPU, memory, and storage is essential to ensure efficient and cost-effective cloud operations. This will prevent over or under-allocation of resources. Additionally, by using well-adjusted auto-scaling rules within predefined limits to adapt to workload changes, you can ensure that resources are utilized effectively and costs are minimized.

Integrating with DevOps and Continuous Deployment

For the best results in cloud computing, it is crucial to merge resource management with DevOps practices without any gaps. The key to achieving this is automation, which makes deploying apps and managing infrastructure changes seamless through DevOps pipelines. Moreover, it is essential to follow Infrastructure as Code principles to keep cloud resources in check.

Staying Ahead in the Ever-Evolving Cloud Landscape

Cloud elasticity is vital in today’s dynamic tech landscape. Scale resources up or down as seasonal demand fluctuates, optimize costs, and enhance user experiences. Implement auto-scaling, monitor metrics, and leverage cloud-native services for agility and efficiency. Stay elastic to succeed in the cloud environment.
