GCP Topology

Question 1

Preemptible VM

Answer 1

Google can delete complete VM without intimation

Question 2

Containers

Answer 2

A container is a standard unit of software that
packages up code and all its dependencies so the application
runs quickly and reliably from one computing environment to
another.

Question 3

Benefits of Container

Answer 3

The container will automatically allocate that memory from the base hardware s/m. So if our application at start is taking 8 GB and after sometime if its taking 2 GB, then the container will release rest of the 6GB machine which was allocated initially. Container will demand the memory required to run the process not the complete VM. We don’t have hard-coded configuration for memory for the CPU.

Question 4

Docker

Answer 4

Docker is a facility which will execute the container on the machine

Question 5

Kubernetes

Answer 5

Kubernetes is an open source container
orchestration platform that automates many of the manual
processes involved in deploying, managing, and scaling
containerized applications.

Question 6

HELM

Answer 6

Helm charts are packages that contain all the
information that Kubernetes needs to know for managing a
specific application within the cluster

Question 7

Google App Engine

Answer 7

Platform as a Service (PaaS)

Question 8

2 Types of App Engine

Answer 8

Standard App Engine
&
Flexible App Engine

Question 9

App Engine Standard

Answer 9

➤App Engine standard environment is based on
container instances running on Google’s infrastructure.
➤App Engine standard environment makes it easy to build and
deploy an application that runs reliably even under heavy load
and with large amounts of data.
➤ Free Daily Quota.
➤ Usage based Billing.

Question 10

Flexible App Engine

Answer 10

➤ Customizable infrastructure - App Engine flexible
environment instances are Compute Engine virtual machines,
which means that you can take advantage of custom libraries,
use SSH for debugging, and deploy your own Docker containers.
➤ Performance options - You can specify how much CPU and
memory each instance of your application needs, and the flexible
environment will provision the necessary infrastructure for you.
➤ Native feature support - Features such as microservices,
authorization, SQL and NoSQL databases, traffic splitting,
logging, versioning, security scanning, and content delivery
networks are natively supported.

Question 11

Persistent Disk

Answer 11

➤Single root disk attached to VM.
➤Common and Default Option
➤Not Directly attached to Compute Engine, but via Network interface
* Benefit of RAID (Redundant Array of Independent Disks)

➤ Standard and SSD options available

Question 12

Local SSD

Answer 12

➤Directly attached to Compute Engine VM

Question 13

Cloud Storage Bucket

Answer 13

➤Infinite Space
➤No Block Storage allowed.
