 Once a canister's code has been written, it must be compiled into Wasm, installed into the canister itself, and then deployed to a network. The `dfx deploy` command executes each of these tasks as part of the deployment process; however, `dfx` commands also exist for running each step individually.
 
 It is recommended to deploy canisters locally or to the temporary [playground](/docs/current/developer-docs/smart-contracts/deploy/overview#deploying-to-playground) network to test canister functionality and make adjustments before considering the canister production-ready and deploying it to the mainnet. Deploying canisters locally and to the playground is free and does not cost cycles. Once a canister is deployed to the mainnet, it will consistently consume cycles and will need to be topped up periodically.

 To prevent a canister from running out of cycles and being deleted, you can set what is known as a **freezing threshold**. This threshold is a duration of time set in seconds, indicating the minimum duration that the canister should exist without running out of cycles. Once a canister hits this threshold, it will not execute messages. It will only pay for the network resources it uses, such as compute allocation, memory usage, and storage allocation.
