🌐 Introduction to Cloud Computing Services

This paragraph introduces the concepts of Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) within the context of virtualized data centers. IaaS provides on-demand infrastructure resources such as compute, storage, and network capabilities, which are virtualized to resemble physical data centers. Google Cloud's Compute Engine is cited as an example of an IaaS service. PaaS, on the other hand, focuses on binding code to libraries that facilitate access to infrastructure, allowing developers to concentrate more on application logic rather than infrastructure management. Google Cloud's App Engine is given as an example of a PaaS service. The payment models differ between IaaS and PaaS, with IaaS requiring payment for allocated resources in advance and PaaS charging for actual usage. The paragraph also discusses the shift towards managed infrastructure and services in cloud computing, which enables companies to focus on their business objectives more effectively. It highlights the benefits of managed services in terms of quicker and more reliable delivery of products and services. The concept of Serverless computing is introduced as an evolution of cloud computing, where developers can focus solely on their code without worrying about server configuration, thanks to services like Google Cloud Functions and Cloud Run. Lastly, the paragraph briefly mentions Software as a Service (SaaS), which delivers entire applications over the internet, with Google Workspace applications like Gmail, Docs, and Drive serving as examples.

Keywords

💡Virtualized Data Centers

Virtualized data centers are a concept where physical infrastructure is abstracted into virtual resources that can be managed and provisioned dynamically. This allows for more efficient use of resources and scalability. In the context of the video, the shift to virtualized data centers introduced new service models like IaaS and PaaS, which are designed to provide customers with flexible and on-demand computing resources.

💡IaaS (Infrastructure as a Service)

IaaS refers to a model of cloud computing where the provider offers virtualized computing resources over the internet. It includes raw compute, storage, and network capabilities that are delivered on-demand and are similar to physical data centers. An example given in the script is Google Cloud's Compute Engine, which allows customers to allocate these resources ahead of time and pay for what they use.

💡PaaS (Platform as a Service)

PaaS is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. The script mentions Google Cloud's App Engine as an example of PaaS, where the service binds code to libraries that provide access to the infrastructure an application needs.

💡Managed Infrastructure

Managed infrastructure in cloud computing refers to the services provided by cloud vendors that handle the maintenance, management, and operation of the underlying hardware and software. This allows businesses to focus on their core competencies rather than on managing the technical infrastructure. The video emphasizes the momentum shift towards managed infrastructure and services as a way for companies to concentrate more on their business goals.

💡Serverless

Serverless computing is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. It allows developers to build and run applications and services without thinking about servers. The video explains that serverless technologies like Google Cloud Functions and Cloud Run eliminate the need for infrastructure management, enabling developers to focus solely on their code.

💡Cloud Functions

Google Cloud Functions is a serverless execution environment that allows developers to create and run functions without having to manage a server or runtime environment. It is an event-driven, pay-as-you-go service that automatically scales based on the number of requests. The script positions Cloud Functions as part of the serverless evolution in cloud computing.

💡Cloud Run

Google Cloud Run is a managed platform that enables you to run stateless containers that are invocable via web requests or Pub/Sub events. It is part of the serverless offerings by Google Cloud, allowing customers to deploy containerized microservices-based applications in a fully managed environment, as mentioned in the script.

💡SaaS (Software as a Service)

SaaS is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. Typically, SaaS applications are accessed one at a time, with a subscription or pay-as-you-go fee structure. The video gives examples of Google Workspace applications like Gmail, Docs, and Drive, which are consumed directly over the internet by end users.

💡Compute Engine

Google Compute Engine is a part of Google Cloud Platform that provides IaaS, allowing users to create and run virtual machines on Google's infrastructure. It is an example of how IaaS delivers on-demand infrastructure resources, as discussed in the script.

💡App Engine

Google App Engine is a PaaS that allows developers to build and host web applications in Google-managed data centers. It abstracts away the infrastructure, allowing developers to focus on writing code and not managing servers. The script uses App Engine to illustrate how PaaS offerings enable more resources to be focused on application logic.

💡Event-driven

Event-driven computing is a programming paradigm where the flow of the program is determined by events such as user actions, messages, or sensor outputs. In the context of the video, Google Cloud Functions is described as an event-driven service, which means it responds to events and triggers the execution of code in response to these events.
