Cloud Elasticity Vs Cloud Scalability

This concept has close connections to the term ‘economies of scale’. This is when certain companies are able to cut down their production costs and increase profitability. Specifically, while they are steadily growing larger and producing more. For situations when expanding production leads to an increase in costs and profit decrease, the term is ‘diseconomies of scale’. Cloud scalability is an effective solution for businesses whose needs and workload requirements are increasing slowly and predictably.

Scalability vs Elasticity

For example, scaling up makes hardware stronger; scaling out adds additional nodes. Elasticity is the ability to scale up and down to meet requirements. You do not have to guess capacity when provisioning a system in AWS. AWS’ elastic services enable you to scale services up and down within minutes, improving agility and reducing costs, as you’re only paying for what you use. If we need to use cloud-based software for a short period, we can pay for it instead of buying a one-time perpetual license.

The system starts on a particular scale, and its resources and needs require room for gradual improvement as it is being used. The database expands, and the operating inventory becomes much more intricate. Diagonal scale is a more flexible solution that combines adding and removing resources according to the current workload requirements.

Aws And Elasticity: Keeping Ahead Of User Demand

System scalability is the system’s infrastructure to scale for handling growing workload requirements while retaining a consistent performance adequately. The notification triggers many users to get on the service and watch or upload the episodes. Resource-wise, it is an activity spike that requires swift resource allocation. Thanks to elasticity, Netflix can spin up multiple clusters dynamically to address different kinds of workloads. The ability to increase or decrease the resources quickly based on the need and to make sure that it doesn’t affect the performance of the application. These five qualities describe a deeply flexible and highly automated system whose elements can be freely mixed and matched to provide the most efficient and cost-effective service possible.

Either increasing or decreasing services and resources this is a planned event and static for the worse case workload scenario. A use case that could easily have the need for cloud elasticity would be in retail with increased seasonal activity. For example, during the holiday season for black Friday spikes and special sales during this season there can be a sudden increased demand on the system. Instead of spending budget on additional permanent infrastructure capacity to handle a couple months of high load out of the year, this is a good opportunity to use an elastic solution. The additional infrastructure to handle the increased volume is only used in a pay-as-you-grow model and then “shrinks” back to a lower capacity for the rest of the year.

Existing customers will also revisit abandoned trains from old wishlists or try to redeem accumulated points. There will often be monthly pricing options, so if you need occasional access, you can pay for it as and when needed. When the project is complete at the end of three months, we’ll have servers left when we don’t need them anymore.

  • Virtualization is the creation of virtual servers, infrastructures, devices and computing resources.
  • Cloud scalability is an effective solution for businesses whose needs and workload requirements are increasing slowly and predictably.
  • Let’s say a customer comes to us with the same opportunity, and we have to move to fulfill the opportunity.
  • Cloud elasticity combines with cloud scalability to ensure that both the customer and the cloud platform meet changing computing needs when the need arises.

This may become a negative trait where performance of certain applications must have guaranteed performance. Caching on the cloud with AWS is the ability to deliver your content through a worldwide network of data centers called edge locations. AWS CloudFront is a simple to use CDN service that is built for high performance and security and can transfer content with high transfer speed. If you take advantage of AWS’s CloudFront Service, the request is routed to the nearest edge location and Geo targeting service to the user, thus reducing latency. What is the difference between an AWS availability serve and Edge location?

Elasticity, or fully automatic scalability, takes advantage of the same concepts that semi-automatic scalability does but removes any manual labor required to increase or decrease capacity. Everything is controlled by a trigger from the System Monitoring tooling, which gives you this “rubber band” effect. If more capacity is needed now, it is added now and there in minutes.


There are an expected number of desktops based on employee population. To ensure the ability to support the maximum number of users and meet SLAs, the amount of services purchased must be enough to handle all users logged in at once as a maximum use case. In short, the amount of resources allocated are there to handle the heaviest predicted load without a degradation in performance.

These are commonplace and are very useful in many of today’s applications. Many use these terms interchangeably, but there are distinct differences between them. Knowing about these differences and understanding them is crucial to ensuring that the needs of a business are met. Next up, we’ll highlight the differences that come into play in the scalability vs elasticity debate and what that means for the future of blockchain. Much debate has centered around the scalability vs elasticity topic regarding blockchains. Today, we delve into what each of these terms means and what they signify for the future of blockchain technology.

Cloud elasticity combines with cloud scalability to ensure that both the customer and the cloud platform meet changing computing needs when the need arises. Depending on the type of cloud service, discounts are sometimes offered for long-term contracts with cloud providers. If you are willing to charge a higher price and not be locked in, you get flexibility. Elasticity allows a cloud provider’s customers to achieve cost savings, which are often the main reason for adopting cloud services.

Scalability vs Elasticity

CIOs, cloud engineers, and IT managers should consider when deciding to add cloud services to their infrastructure. Cost, security, performance, availability, and reliability are some common key areas to consider. Another criterion that has been added to the list recently is cloud scalability and cloud elasticity. It is important to not allow yourself to fall into the sales confusion of services. To elaborate, where the presentation of cloud elasticity and scalability by public cloud providers are as the same service. For example, there is a small database application supported on a server for a small business.

Having a cloud service helps businesses to change their resource allocation in the production line. Elasticity uses dynamic variations to align computing resources to the demands of the workload as closely as possible to prevent wastage and promote cost-efficiency. Another goal is usually to ensure that your systems can continue to serve customers satisfactorily, even when bombarded by heavy, sudden workloads. Vertical scaling allows customers to add and remove instances manually and typically requires downtime. Horizontal scaling, or also referred to auto scaling allows customers to configure and scale additional instances when needed and scale back in.

What Is The Benefit Of Elasticity In The Aws Cloud?

If there are not enough pods running it will spin up more; or if there are too many pods running it will terminate the extra pods. Solutions Review gathers all of the most relevant content about Enterprise Cloud solutions and posts it here. In the computer world, “flexible” may refer to hardware, software, or a combination of the two. It describes a device or program that can be used for multiple purposes, rather than a single function.

Scalability vs Elasticity

Cloud elasticity is the process by which a cloud provider will provision resources to an enterprise’s processes based on the needs of that process. Cloud provides have systems in place to automatically deliver or remove resources in order to provide just the right amount of assets for each project. For the cloud user, they will be given enough power to run their workflows without wasting money on any supplied resources they don’t need. For scalability, scaling up is an individual increasing their power in order to meet the increasing demands. Scaling out, meanwhile, is constructing a team to meet the growing demands. For elasticity, it’s an actor changing their body weight to meet the numerous demands of the film industry.

Virtualization is the creation of virtual servers, infrastructures, devices and computing resources. Virtualization changes the hardware-software relations and is one of the foundational elements of cloud computing technology that helps utilize the capabilities of cloud computing to the full. In a hybrid cloud model, enterprises deploy workloads in private IT environments or public clouds and move between them as computing needs and costs change.

Cloud Elasticity Vs Scalability: Main Differences To Know About

Two of these comparable terms include ‘scalability’ and ‘elasticity’. If you take their most basic definitions, they seem to mean the Difference Between Scalability and Elasticity in Cloud Computing same – if not almost the same – thing. Scalability focuses on coping with expansion and elasticity equates to sensitivity to changes.

Let’s say a customer comes to us with the same opportunity, and we have to move to fulfill the opportunity. Using predefined, tested, and approved images, every new virtual server will be the same as others , which gives you repetitive results. It also reduced the manual labor on the systems significantly, and it is a well-known fact that manual actions on systems cause around 70 to 80 percent of all errors. There are also huge benefits to using a virtual server; this saves costs after the virtual server is de-provisioned. Another downside of manual scalability is that removing resources does not result in cost savings because the physical server has already been paid for.

It adapts to both the workload increase as well as workload decrease. This is purely by way of provisioning and de-provisioning resources; specifically, in a manner that is autonomic. Turbonomic allows you to effectively manage and optimize both cloud scalability and elasticity.

What Is Aws Scalability

Over time as the business grows so will the database and the resource demands of the database application. In other words, scale up performance without having to worry about not meeting SLAs in a steady pay-as-you-grow solution. The main reason for cloud elasticity is to avoid either overprovisioning and underprovisioning of resources.

System Scalability & Elasticity

Manual scalability begins with forecasting the expected workload on a cluster or farm of resources, then manually adding resources to add capacity. Ordering, installing, and configuring physical resources takes a lot of time, so forecasting needs to be done weeks, if not months, in advance. It is mostly done using physical servers, which are installed and configured manually. Ability to dynamically scale the services provided directly to customers’ need for space and other services.

Combining these features with advanced image management capabilities allows you to scale more efficiently. Most implementations of scalability are implemented using the horizontal method, as it is the easiest to implement, especially in the current web-based world we live in. Vertical Scaling is less dynamic because this requires reboots of systems, sometimes adding physical components to servers. Rapid elasticity and scalability should be regarded as the landmark signature characteristics of cloud computing.

Scalability Vs Elasticity In Cloud Computing

Elasticity is a crucial concept in cloud-native application designs, due to most cloud providers, such as AWS, operating upon a pay-per-use model. It is certainly possible to transfer AWS-based applications from lighter to heavier servers, and for some payloads — like many high-load transaction databases, it’s preferred. But in an AWS context, if you hear some conjugation of the word “scale”, the odds are that it’s referring to horizontal scaling. A system is said to be scalable if it can increase its workload and throughput when additional resources are added. A related aspect of scalability is availability and the ability of the system to undergo administration and servicing without impacting applications and end user accessibility. The services have become very flexible and can be altered according to the business needs of a company.

Over-provisioning refers to a scenario where you buy more capacity than you need. It works to monitor the load on the CPU, memory, bandwidth of the server, etc. When it reaches a certain threshold, we can automatically add new servers to the pool to help meet demand. When demand drops again, we may have another lower limit below which we automatically shut down the server. We can use it to automatically move our resources in and out to meet current demand.

After that, you can return the excess capacity to your cloud provider and keep what is doable in everyday operations. At work, three excellent examples of cloud elasticity include e-commerce, insurance, and streaming services. But Elasticity Cloud also helps to streamline service delivery when combined with scalability. For example, by spinning up additional VMs in the same server, you create more capacity in that server to handle dynamic workload surges. Cloud elasticity helps users prevent over-provisioning or under-provisioning system resources.
