The outcome of the above techniques was a reduction of 33% in monthly costs. Elasticity in cloud computing is a pivotal feature that allows resources to scale dynamically based on demand. According to Wikipedia elasticity is defined as “the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible. A well-designed app scales up and down as demand increases and decreases, and is resilient enough to withstand service disruptions. However, the aforementioned approaches usually provision virtual machines (VMs) in a coarse-grained manner just by the CPU utilization. In cloud computing, cloud scalability refers to the ability of increasing or decreasing the IT resources to meet changing needs. Cloud solutions architects should ideally “build today with tomorrow in mind,” meaning their solutions need to cater to current scale requirements as well as the anticipated growth of the solution. This provides a consistent and predictable experience without the risk of servers failing or becoming unavailable. This is why many businesses opt for cloud migration. Cost-effectiveness. In other words, elasticity in cloud computing refers to the ability of a cloud to automatically expand or compress the infrastructural resources on a sudden up and down in the requirement so that the workload can be managed efficiently. Elastic scaling is a core characteristic of the VMware NSX Advanced Load Balancer that allows it to automatically create (scale out) or delete (scale in) SEs to adjust capacity based on end-user traffic and virtual service health scores.
