Key Takeaways

The cloud is simply renting computing resources: Instead of buying physical hardware, individuals and businesses securely rent computing power, storage, and software over the internet.
Virtualization powers the cloud: Providers use virtualization software to divide massive physical servers into multiple, independent Virtual Machines (VMs) for different users.
There are three main service models: Cloud offerings are broken down into IaaS (raw infrastructure), PaaS (developer environments), and SaaS (ready-to-use software applications).
Deployments fit specific needs: Organizations can choose between public, private, hybrid, or serverless cloud environments based on their required levels of security, control, and flexibility.
The cloud shifts IT costs: It moves hardware spending from large upfront capital investments to pay-as-you-go operating expenses.
Scalability and recovery are built-in: The cloud allows for on-demand scalability to seamlessly handle traffic spikes and ensures reliable disaster recovery through globally backed-up data.
Security requires shared responsibility: While cloud providers invest billions in cyber defense, the most common vulnerabilities are user-generated, such as database misconfigurations, unsanctioned "Shadow IT", and cryptojacking.
