Cloud Foundations Part I Flashcards
Introduction to Computing, Basic Computing Concepts, What is Cloud Computing?, Cloud Roles, Advantages of Cloud Computing, What is AWS?
A computer program. It’s a set of instructions that run on a computer to perform a specific function.
Application
Java, Python, and C++ are examples of ______.
Programming Languages
Refers to a computer’s physical components, such as its central processing unit (CPU), memory, and storage drive.
Hardware
The collection of applications and programs that are installed on the computer. It includes an operating system (OS) such as Amazon Linux, and an application such as the Amazon Shopping Mobile App.
Software
Memory, also called _______, is the hardware component that stores the OS, application programs, and data in current use.
RAM
The basic unit of measurement for memory.
bytes
Enables different computers to connect and communicate with each other.
Computer Network
A computer that provides resources or services to other computers over a network.
Server
A physical location that is used to host computer systems and associated components such as networks, storage devices, and power supplies.
Data Center
A software-based computer that runs inside a physical computer.
Virtual Machine (VM)
A process that’s used to produce software in a disciplined and organized way.
Software Development Life Cycle (SDLC)
On-demand delivery of compute power, database, storage, applications, and other IT resources.
Cloud Computing
A cloud service model where you manage the server, which can be physical or virtual, and the operating system (Microsoft Windows or Linux). In general, the data center provider has no access to your server.
infrastructure as a service (IaaS)
A cloud service model where someone else manages the underlying hardware and operating systems. In this way, you can run applications without managing underlying infrastructure (for example, patching, updates, maintenance, hardware, and operating systems).
platform as a service (PaaS)
A cloud service model where you manage your files while the service provider manages all data centers, servers, networks, storage, maintenance, and patching. You handle only the software and how you want to use it.
software as a service (SaaS)
