Infura is a vital infrastructure service that provides seamless access to Ethereum blockchain nodes. For Solidity developers, Infura offers a reliable means to interact with the Ethereum network without needing to run and maintain their own Ethereum node. This alleviates the need for extensive resources and technical knowledge to set up a node, allowing developers to focus on writing and deploying their smart contracts.

By using the Infura API, developers can easily send transactions, query data, and access various functionalities of the Ethereum blockchain. This is particularly beneficial for DApp developers who require consistent and low-latency access to Ethereum for their applications.

The other options address functions that are not the primary focus of Infura. While compiling Solidity code is part of the development cycle, it is done through other tools like Remix or Truffle. Hosting decentralized applications involves various other services and platforms beyond what Infura provides, which primarily focuses on node access. Though Infura may help in deploying smart contracts, it does not permanently store them; the contracts are stored on the Ethereum blockchain itself, independent of any third-party service.
