Describe the components involved in how websites work based on the provided content.
Websites involve servers, networks, clients with IP addresses, and servers with IP addresses. Client communicates with the network which then in turn communicates with the server.
Define the role of a server in the context of websites based on the provided content.
Servers play a crucial role in hosting website data and serving it to clients over a network.
How are clients and servers differentiated in terms of IP addresses according to the content?
Clients and servers both have IP addresses, with clients using them to request data and servers using them to send requested data.
Describe the components that make up a server according to the provided content.
A server is composed of compute (CPU), memory (RAM), storage (data), database (for storing data in a structured way), and network components (routers, switches, DNS server).
Describe a network in IT terminology.
A network in IT terminology refers to cables, routers, and servers connected with each other.
Define a router in IT terminology.
A router is a networking device that forwards data packets between computer networks and knows where to send packets on the internet.
How does a switch function in IT terminology?
A switch takes a packet and sends it to the correct server/client on your network.
Explain the role of a switch in a network.
In a network, a switch is responsible for directing packets to the appropriate destination server or client.
What is the purpose of a router in IT networks?
Routers in IT networks are used to forward data packets between different computer networks and determine the path for packet delivery.
Describe the traditional ways of building infrastructure according to the provided content.
The traditional ways include setting up infrastructure in a data center, at home or in a garage, and in an office.
Describe the problems with the traditional IT approach outlined in the content.
The traditional IT approach involves paying for data center rent, power supply, cooling, maintenance, limited scaling, hiring a 24/7 monitoring team, and addressing disaster recovery concerns like earthquakes, power shutdowns, and fires.
Define the need for externalization in the context of IT infrastructure.
Externalization in IT infrastructure refers to outsourcing data center operations, maintenance, and monitoring to third-party service providers to alleviate the burden on internal resources and improve scalability and disaster recovery capabilities.
How can externalizing IT infrastructure help address the challenges mentioned in the content?
Externalizing IT infrastructure can reduce costs, improve scalability, enhance disaster recovery capabilities, and streamline operations by leveraging the expertise and resources of specialized service providers.
Describe Cloud Computing.
Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform with pay-as-you-go pricing.
What does cloud computing allow you to do in terms of computing resources?
Cloud computing allows you to provision exactly the right type and size of computing resources you need and access as many resources as you need almost instantly.
Define the role of Amazon Web Services in cloud computing.
Amazon Web Services owns and maintains the network-connected hardware required for application services, while users provision and use what they need via a web application.
Describe Gmail as a cloud service.
Gmail is an email cloud service where users pay only for the emails stored, without having to manage infrastructure.
Define Dropbox as a cloud service.
Dropbox is a cloud storage service that allows users to store and access their files online, originally built on AWS.
How is Netflix utilizing cloud services?
Netflix is built on AWS and offers video-on-demand services to its users, leveraging cloud infrastructure for content delivery.
Describe the Private Cloud deployment model in the context of cloud computing.
Private Cloud involves cloud services exclusive to a single organization, offering complete control, security for sensitive applications, and tailored solutions to meet specific business requirements.
