Data Centers Solution Elements

Question 1

Infrastructure as a code

Answer 1

Using code to manage configurations and automate provisioning . Used to to define and provision networking components (servers,network, storage) that can be version control, tested, automated through machnie-readable files rather than physical hardware configuration

Question 2

Elasticity

Answer 2

Is the availability to fit the resources needed to cope with loads dynamically. When load increases, more resources are added and when demand decreases resources are removed

Question 3

Micro services

Answer 3

Breaking down large application into smaller, independently deployable components that perform specific business function or task. Software development approach.each micro-service is a self-contained component that can be deployed, updated, scaled independently without affecting the rest of application

Question 4

Containerization

Answer 4

Is a technology that allows applications to be packaged and run in isolated environments called containers. Containers provide a way to isolate apps and their dependencies from the underlying infrastructure, which makes it easier to deploy, manage and scale apps across different environments

Question 5

Automation

Answer 5

Is the application of the technology, programs, robots or processes to achieve outcomes with a minimal human input. Increase quality, reduce errors

Question 6

Scalability

Answer 6

I’d the ability of the system to automatically accommodate layer loads by adding resources - either making hardware stopper (scale up) or adding additional nodes (scale out)

Question 7

node

Answer 7

This is unit of data structure, linked list or tree data structure . Nodes contain data and also may link to other nodes

Question 8

Chestration

Answer 8

Is the integration of the tools and platforms for an automatic response

Question 9

Demand generated

Answer 9

Resource allocation is the automatic provisioning and deprovsioning of resources

Question 10

Software defined networking

Answer 10

Using software to manage and configure the network infrastructure, instead changing configuration of physical equipment. Is made possible by separating the control plane is moved to centralized controller that manages the network devices. Relies on centralized controller.

Question 11

Services computing

Answer 11

Dynamic allocation of resources to execute a specific of code. This is an execution model in which a cloud provider dynamically allocates only the compute resources and storage needed to execute a particular piece of code. Functions are event-driven, meaning the code is invoked only when triggered by a request
