6: 3 Cloud Building Blocks

Question 1

Virtualized Servers

Answer 1

Run in cloud data centers

Question 2

Machine Image

Answer 2

Template of OS and other software/machine characteristics for the server being created

Question 3

Instance Type

Answer 3

Different configurations of processor/computing details of the server being created

Question 4

Security Group

Answer 4

Firewall rules for instance

Question 5

Key pair

Answer 5

Key used to access the machine as it launches

Question 6

Splitting user resources across zones

Answer 6

Insulates against failures in a single zone

Question 7

Storage

Answer 7

Fundamental building block of cloud, stores and archives data

Question 8

Block Storage

Answer 8

Allocate large chunk of storage and partition it (hard drive), managed by an OS

Question 9

Object Storage

Answer 9

Stores files as individual objects managed by the cloud service provider

Question 10

Price of block vs object`

Answer 10

Object storage is much cheaper - only pay for what you need, not what you can need

Question 11

Cloud Storage Security Issues

Answer 11

1) Permissions properly
2) Encrypt sensitive data
3) Replicate copies of data to multiple data centers

Question 12

vLAN

Answer 12

Virtual LAN - separate systems of differing security levels

Question 13

VPC

Answer 13

Virtual Private Cloud - Can create instances for different security levels

Question 14

VPC Endpoints

Answer 14

Provide secure VPC interconnection

Question 15

SDN

Answer 15

Software Defined Networking - Automates cloud networking (integrates cloud providers API into your operations stack).

Question 16

SDV

Answer 16

Software Defined Visibility - Uses cloud providers API to gain visibility into network traffic

Question 17

Build Database on Virtualized Server

Answer 17

Resembles on-premises operations, requires customer managed of servers/databases, spinning up a server and installing databases on them

Question 18

Using a managed database service

Answer 18

Request database from cloud provider using platform of choice, and then cloud provider holds maintenance (more expensive)

Question 19

Using a Cloud-native database paltform

Answer 19

Allows use of database environments designed specifically for cloud, high degree of optimization but requires retooling of existing applications. Places management burden on the provider.

Question 20

Hybrid Environments

Answer 20

Balancing workload between private cloud and private datacenters

Question 21

Cloud orchestration

Answer 21

Automates cloud management

Question 22

Infrastructure as Code

Answer 22

Admins should never build/manage resources using command line - should write code that performs such functions.

Question 23

Containers

Answer 23

Lightweight application virtualization - so it can easily move between hardware platforms. Lightweight alternative to virtual servers, using host OS.

Question 24

What do containers contain

Answer 24

Application code and dependencies only

Question 25

What do contains run on

Answer 25

Containerization platforms, not hypervisor
