# Elastic
Rollups launched via AltLayer's RaaS offerings are highly elastic in the sense that they can scale with the application. If an application hits the capacity of a rollup to a point where a single rollup supporting an application may not provide the best user experience, one can easily spin up more rollups. Additionally, when an application needs to shrink its infrastructure capacity, rollups can be taken down.
The ability to take down a rollup is implemented in the form of a new type of rollup called flash layers. These rollups are ephemeral in nature and upon their disposal, all the assets and NFTs minted on the rollup get settled on the underlying chain.
