Highlights
The speaker introduces the topic of cloud computing, realizing she has often discussed cloud security without first defining cloud computing. She shares an anecdote about a friend who didn't understand the cloud until it was related to iCloud on her iPhone, motivating the video's explanation of what cloud computing is, its common uses, and how to explain it to others. She also briefly introduces herself as a Cloud Security Architect.
Cloud computing is defined as bringing data and applications to you via internet accessibility. Instead of storing data directly on physical devices with limited storage, data is stored in the cloud. The 'cloud' refers to online servers that host your data, documents, and applications. This concept allows users to access information and applications from anywhere with an internet connection, facilitating collaboration.
The video breaks down cloud computing into three primary categories: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).
SaaS examples include Gmail, Dropbox, and Slack. In SaaS, the cloud provider manages most responsibilities, while the user is responsible for securely accessing the application (e.g., strong passwords, multi-factor authentication) and the data within their account.
PaaS allows cloud providers to host the infrastructure for building applications. This is beneficial for developers as they don't need to worry about underlying network or virtual machine configurations. Examples include AWS Elastic Beanstalk and Microsoft Power Platform, where developers can deploy and run their code.
IaaS involves utilizing more of the cloud provider's underlying infrastructure. The cloud provider hosts servers, compute, and networking, but the user deploys virtual machines and selects the operating system, controlling what runs on top of it. Examples include Azure Virtual Machines, AWS EC2 instances, and Google Cloud Compute Engine.
The cloud makes it easier to access and collaborate on information online, offering scalability and flexibility without upfront hardware investment. However, securing these cloud-based models is crucial, which leads to the importance of cloud security. The speaker promises to discuss her role as a cloud security professional in the next video.
