Elasticity is a property of Econocloud architecture. . But what is elasticity? It is the possibility to grow or shrink automatically according to a set of predetermined conditions (metrics, triggers). This feature ensures that we can provide an excellent online experience for our customers when they browse our websites.
Elasticity is often confused with scalability. In fact, scalability es intrínseca a la elasticidad: is intrinsic to elasticity – being scalable usually refers only to a platform’s ability to grow in a planned way.
It is easier to achieve elastic architectures from the tools provided by the cloud, especially through virtualization and pay-per-use.
Applied to the server environment, elasticity is characterized by working in both directions: expansion or reduction of platform resources, and beinginstantaneous and automatic – it does not require our intervention.
Elasticity enables us to maintain the quality of service to users regardless of the number of requests. Here are four more benefits of elasticity:
- Reduced downtime (redundant architectures).
- In the event of unavailability, recovery time is reduced (the nodes have no state, there are templates of everything). After all, it is easier to replace than to fix.
- Autohealing policies can be implemented.
- Saving costs due to oversizing through the use of a pay-per-use model.
Elasticity applied to ICT infrastructures is one of the key factors that make it possible to provide cloud computing services such as Econocloud, by provisioning and de-provisioning resources without changing servers or making scheduled stops.
