The cloud computing ecosystem is huge and consists of several technologies. Many companies rely on these varying cloud infrastructure to deliver their products and services efficiently. This brings up the question, how scalable is your cloud architecture?
Using the right architecture is extremely crucial for your entire cloud’s operation. It is important that organizations understand the specific requirements of their servers, and if they are already using a cloud platform, decide on the type of cloud architecture that would be best for their business logic.
Before choosing a cloud computing architecture, the first thing that’s required is a scalable structure. Cloud computing is scalable when all its components are independent of each other. This independence allows systems to scale at exceptional levels and is usually implemented at the design stage.
Features of a Scalable Cloud Architecture
Typically, cloud computing systems involve different cloud components communicating with each other on a system that functions like a messaging lineup. How these components interact is what determines the scalable nature of your infrastructure. There are two layers that make up a scalable cloud architectures:
1. The Client / Front-end
The client structure is where all users interface with the target platform. This is usually the mobile or web application that manages users, sessions and pages. The client usually makes API calls to the server.
The front-end comprises of single user or a network of users. Note that some front-ends will not look like the regular applications we see everyday. The main thing to remember during the design stage is that this is the layer that communicates with the back-end. Therefore RESTful calls to the back-end is the main purpose during the front-end design stage. Whatever visual design you build into your cloud’s front-end, making API calls to the server is the main focus at this stage.
2. Server / Back-end
Your server comprises of data, caching services and all services that interact directly with your server applications. This interaction is necessary for data delivery.
Your server applications drive your business functions and can include apps like CRM, inventory, accounting, reservation system and much more. Adding new applications is part of scalability, so as you add new applications, the demands of higher traffic and computing loads must be anticipated. Your front-end will not automatically scale to size unless you ensure that your back-end accommodates the new load and traffic.
For best practices in maintaining and protecting client’s data, a cloud computing structure requires a high level of redundancy than is necessary for a system hosted locally. The backup created by this redundancy means that the back-end server can jump in and access backup images for quick restoration of data.
In a highly scalable cloud computing architecture, applications are managed, controlled and served by the back-end. The strength of the back-end is how it manages security protocols, traffic and system files. If the applications on your server are broken down and classified into sub-components of the main server, your cloud infrastructure will deliver limitless efficiency and possibilities, making scalability much easier.
