Scalability = Operational Flexibility
Scalability is a systems characteristic which enables a platform hosting a system to automatically muster additional computing resources as the system workload increases.
In a cloud world, a scalable system is a system which is able to automatically provision additional computing resources such as processor, memory and bandwidth as the demand for computing resources from the hosted system increases.
Scalability meets user expectations
Users interacting with online services expect systems to be perpetually available, function at peak performance levels and have a user interface design which is aesthetically pleasing, intuitive and simple to use.
Scalability’s purpose as a feature of online services is to ensure a system is able to function at the performance levels expected by its users.
Scalability and its impact on availability
Downtime in an online world is not good for business. Ensuring systems availability has multiple real-world business benefits which impact the profitability and brand reputation of an organisation.
In today’s business world, all revenue-based transactions are processed via an IT system or application. This is true for both online e-commerce type transactions as well as traditional invoice runs on an in-house financial application. If a revenue-generating system is down the business cannot make money.
Scalability ensures online systems availability during periods where services are under heavy load. Services which are not able to scale will ultimately stop responding and go offline when all the allocated computing resources for the system have been consumed. The system can only start responding again if existing locked resources are released or additional resources added.
Scalability, therefore, benefits businesses by ensuring services and applications stay online and functional.
Poor performance and unavailability are punished in an online world
Most modern organisations interact with their customers through some form of online platform.
Social media has enabled organisations to interact with their customers on many different levels which have strengthened customer relationships. However, social media has also given consumers a platform to voice their grievances to the organisation while broadcasting these to other customers.
Poor application performance and service unavailability are heavily punished on social media. Businesses should, therefore, ensure they constantly strive to deliver an online service which performs well above the expectations set by its users.
By configuring their applications with a scalable architecture, organisations can ensure their applications perform admirably under heavy load.

Create a hybrid cloud with Zettagrid to facilitate on-premise scalability
Organisations could opt to create a hybrid cloud between their on-premise private cloud and the Zettagrid platform. This configuration gives customers the flexibility to move workloads between their two environments as demand fluctuates.
For periods of high demand, they can run their workload on Zettagrid’s platform which can scale to the resource requirements required.
Once demand decreases customers can simply migrate their workloads back to their private on-premise private cloud.
