Elastic computing plays a pivotal role in managing the cloud servers in cloud computing. As the name suggests, elastic compute services offer a cloud service provider the ability to scale up and down the computing resources like memory, bandwidth, infrastructure, etc. This feature swiftly scales the resources to meet the varying demand of the business automatically using the monitoring tools. 

In this article, we will explain what elastic computing in cloud computing is and a lot more.  

What is an Elastic Computing Service (ECS)? 

Elastic computing service is a type of computing service that gives you the flexibility to allocate the cloud servers and computing resources to match the fluctuating business demands. Moreover, it helps businesses in minimizing infrastructure costs, reducing capital expenditures (CAPEX) and operational expenditures (OPEX) offering them high elasticity to meet their business’s ongoing demand. 

In other words, elasticity prevents you from over-provisioning and under-provisioning resources. Moreover, it provides an efficient platform for load balancing in real-time. 

Even though elastic cloud computing comes with concerns like security, it offers many additional benefits. 

Through elastic computing services, businesses can avoid paying for the unused resources and pay only for resources and services they use or need. It offers better efficiency and convenience than physical servers. As ECS uses system monitoring tools, it automatically adds or removes the resources to balance the load. 

Additionally, you don’t need human administrators to monitor the system as ECS stays available round the clock to deploy the resources as and when required. It, in turn, reduces the instances of slowdown and service disruption.

How does elasticity in Cloud Computing work? 

It is often necessary for the elasticity process to occur quickly. If the expansion is delayed, this will cause server overloads and outages. Meanwhile, delays in shrinking could result in some of your servers sitting idle, wasting time and money.

A cloud service that dynamically allocates resources as workloads change is called an elastic environment, where you can take over more resources or release those you no longer require. Moreover, rapid elasticity occurs when a process takes place rapidly or in real-time. 

AWS and Google Cloud are examples of public clouds that support rapid scalability. Cloud providers can provide more elastic cloud services by allocating resources faster to dynamic customer requirements. 

What are the benefits of Elastic Computing Service? 

Innovation in the elastic cloud computing sector is speeding up, driving digital transformation across the IT sector. Let’s explore elastic computing’s benefits and how it impacts organizations. 

Network Capacity 

In addition, to support secure, fast, isolated connections, elastic cloud computing supports virtual private cloud functionality. It supports network capacity at layer two as well as layer three. You are also able to deploy hybrid clouds and cross-cloud using elastic computing services.

Resource Computing & Elasticity

ECS offers various types, sizes, and network cards for cloud services to accommodate your ever-changing business needs. Cloud servers can be adjusted based on business fluctuations. Easy to use console lets you deploy elastic computing service instances quickly. Also, it gives you the flexibility to adjust capacity based on real-time demand.

Cloud Monitoring 

Elastic computing services offer an open cloud monitoring platform that lets you monitor resources in real-time, receive notifications, and make alarms.

Data & Storage 

By creating snapshots, you can back up and roll back the data on your cloud server. This feature increases security and makes snapshot management easier because you have full access to snapshots.

Pay-as-you-go model

With elastic computing services, organizations no longer have to pay extra costs for unused capacity in their data centers. Also, in elastic cloud computing, organizations can avoid huge overhead costs related to adding extra resources to their data centers

Businesses previously had to buy more resources even when they didn’t need them every day in case of unexpected spikes in demand. However, the pay-as-you-go model has solved this issue because you only pay for the resources that you use. 

Easy Management 

From deploying, and maintaining to upgrading your IT infrastructure, elastic compute service allows easy management. It means you don’t need any technical expertise to understand or handle the cloud monitoring platform. As it is virtual, you can access it from any place you like.

Automated Systems

Elastic computing services work on an automated system that runs through the data from time to time. As per the requirement, it adds or removes resources from the server offering high elasticity to the user. 

Additionally, it operates on a highly transparent system that lets you monitor, analyze and control the system. 

Environment-friendly 

Since ECS uses very few resources, it is highly environmentally friendly.  Moreover, it offers great flexibility, agility, and elasticity. 

Resource Pooling 

Cloud computing works on a multi-tenant model that allows multiple users to access the pool of resources. As per the project demand, resources can be assigned, removed, or reassigned to perfectly accommodate the needs. 

Security 

Cloud computing offers optimum security to your website and application and prevents the possibility of data loss under any circumstances. The services offer optimal performance, super-fast speed, reliability, and agility, for instance. 

Types of Elasticity in Cloud Computing 

In cloud computing, elasticity is defined as the system’s ability to allocate or remove resources to easily balance the load variations in real-time. 

In general, Elasticity in Cloud Computing is of two types:

Horizontal 

An application’s horizontal elasticity refers to the addition or removal of instances of computing resources.

Vertical 

An increasing or decreasing characteristic of computing resources, including CPU time, memory, or network bandwidth, is called vertical elasticity.

Applications of Elastic Computing 

Some elastic computing application examples are:

Light-weight enterprise applications

If your business receives average level traffic and all you want is stability at an economical price, opting for standard ECS is the best. The standard ECS comes with computing resources, bandwidth, memory, and network resources. It makes an ideal choice for load balancing. 

Middle-weight enterprise applications

Memory-optimized ECS is suitable for businesses with heavy-data processing. Also, if your application needs high speed or memory, this type of ECS is a good choice. Also, it will provide you with high memory instances and adequate bandwidth to balance the high traffic.  

I/O intensive applications

For the smooth running of I/O intensive applications like CDN or big data analytics, you can go for Ultra-high performing ECS. Moreover, it works best for large datasets. 

How Cloud Cost is related to Elasticity? 

To align computing resources efficiently, elasticity cloud computing uses several dynamic variations that help in aligning computer resources to avoid wastage during over-provision.

What are the limitations of Elastic Cloud computing?

Cloud elasticity comes with immense benefits but that doesn’t mean every business should use it. Cloud stability would do the job just right in case your products or services are getting consistent demand. 

In other words, it is ideal for businesses that do not have to deal with sudden traffic surges or service requests. In such scenarios, you can use Cloud scalability without the need for cloud elasticity. 

What you must remember is that elasticity might need scalability but it is not the other way around. 

For example, if you run a business that doesn’t experience seasonal or occasional spikes in server requests, you may not mind using scalability without elasticity. Keep in mind elasticity requires scalability, but scalability does not need elasticity. 

Conclusion 

Scalability and elasticity are vital parts of cloud computing. Elastic cloud computing can also help you control the cost of the cloud. So, if you do not want the trouble of overprovisioning or under-provisioning, elastic computing is the best solution for you.
