Cloud Computing, Scalability and Elasticity

Introduction

Cloud computing is a very powerful and flexible way to manage your IT services. The cloud allows you to scale up or down your services as needed, and you don’t have to worry about maintenance or hardware failures. This article will explain how scalability and elasticity work together to make cloud computing such an efficient way to run your business.

Scalability

Scaling up and down is a common strategy for managing the costs of cloud computing. It allows you to increase resources when demand increases, and decrease them when demand decreases. The most obvious benefit of this approach is that it avoids paying for resources that are not being used at any given time–a big money saver!

However, there are some drawbacks: scaling up requires more expensive hardware (like servers) than scaling down; so if you need to scale up frequently, you may find yourself spending more than if you had purchased dedicated hardware instead. Additionally, because scaling can take some time depending on how much capacity is needed and what kind of hardware needs upgrading/replacing (it takes longer if it’s physical), there will be delays associated with each change in capacity which could impact performance negatively during those periods.”

Elasticity

Elasticity is the ability to modify a system in order to meet demand. It can be used to describe both hardware and software, but in this context we’ll use it interchangeably with scalability (the ability of a system to increase its capacity).

In cloud computing, elasticity refers to the ability of an application or service provider (e.g., Amazon) to increase or decrease resources on demand without interrupting the user experience. For example: If you’re hosting your website on AWS and get an unexpected spike in traffic due to some news article, they can scale up their servers so that they can handle all of those visitors efficiently without affecting performance for anyone else still using their services at that time.

Cloud Computing

Cloud computing is a model for enabling ubiquitous, 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 or service provider interaction. The cloud model provides:

• On-demand self-service: a consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service’s provider.
• Broad network access: services are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick clients (e.g., mobile phones/tablets).

There are several concepts that go into cloud computing

Cloud computing is a type of computing where the service provider hosts its applications and data. The cloud provider supplies users with access to an extensive pool of virtualized resources, including networks, servers, storage and applications. These resources can be rapidly provisioned with minimal effort by the user who doesn’t have to worry about physical infrastructures such as data centers or hardware maintenance.

Cloud computing provides an abstraction between the infrastructure (e.g., network) and the end-user’s operating system (OS), so that they can focus on their core competencies instead of managing complex infrastructure setups themselves – this is also known as “lift-and-shift” migration strategy for moving workloads from on-premises environments into public clouds like AWS or Azure Cloud Services Platforms

Conclusion

Cloud computing is a very complex topic that can be difficult to understand. I hope this article has helped you better understand the different concepts involved with cloud computing and how they work together.
