Introduction to Digital Transformation with Google Cloud
What is a Cloud?
Defining Cloud Computing
SP 800-145 Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.
This cloud model is composed of five essential characteristics, three service models, and four deployment models.
Cloud computing is the on-demand delivery of compute resources, database storage, applications, and other IT resources through a cloud services platform via the internet with pay as- you-go pricing
Cloud Computing is on demand delivery…..
Cloud Computing and Virtualization are complementary and not the same.
In Cloud Computing your pay for resources used.
NIST Five Essential Cloud Characteristics
On Demand Self Service
Broad Network Access
Resource Pooling
Rapid Elasticity
Measured Service
Some effects of moving from on premises to Cloud Computing:
Localization of cost: From central management to a developer’s hands.
Material spend: No possibility to predict the exact cost of the infrastructure.
Variable price: Spend what you use.
What is Cloud Spend? The estimated monthly dollar amount spend on a company's cloud infrastructure. Public cloud providers bill based on usage and meter costs depending on how much usage is measured, like an electricity bill.
There are three Cloud Service Models – IaaS, PaaS, SaaS
There are four Cloud Deployment Models – Private, Public, Hybrid and Community
Which of the following NIST Five Essential Cloud Characteristics would be used for enabling the sharing of resources between cloud tenants? (Select One)
On Demand Self Service
Broad Network Access
Resource Pooling
Rapid Elasticity
Measured Service
What is TCO
Cloud TCO (total cost of ownership) is the total costs associated with your new cloud technology which is often compared to the total costs of your former server or data center deployment.
The consumer’s Total Cost of Ownership (TCO) of IT services changes while shifting to cloud computing.
Consumers aim to reduce and optimize the TCO expenditure and increase value to business by leveraging new cloud services.
Consumer IT service transition to new cloud service typically increases in transition and then falls as incremental OPEX model is adopted.
ROI is used to measure the success of a potential or ongoing project.
Goal is obtaining a solid ROI and LOW TCO
GCP is a Public Cloud
Hybrid Cloud is when we combine our on premises apps with GCP.
Three Cloud Service Models – IaaS, PaaS, SaaS
Compute Engine is an IaaC solution while App Engine is a PaaS
NIST Five Essential Cloud Characteristics?
Chargeback helps with managing cloud spending.
Difference between Deployment Models?
Vendor Lock in is prevented by open standards.
Which of the following would be considered benefits of using a cloud service such as GCP. (Select Three)
Use of Low-Cost Services
Open and Flexible Service
Supports Open APIs for every service
Secure Services enabled
Services are fully managed
You are currently considering an application that will be hosted on Google Cloud. You want to ensure that if there is an issue with the application that it will be tolerant of any outages. What would describe this requirement? (Select One)
Dependability
Redundancy
Resiliency
Orchestration
Innovating with Data and Google Cloud
Innovating with Data and Google Cloud
What is Google Cloud Platform?
What is GCP?
Google Cloud Platform (GCP), offered by Google LLC, is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its end-user products, such as Google Search, Gmail, file storage, and YouTube.
Public Cloud service hosted by Google
Google is the leader in many areas such
Solid Infrastructure
Top Tier Data Analytics
Serverless leadership
Customer favoring pricing
Innovative Services
Security at Scale
Sub Minute Billing
Sustained Used Discounts
Automatically reward users who run virtual machines for over 25% of any calendar month Compute Engine Custom machines types
Pay only for the resources you need for your application
Google has the most powerful infrastructure and owns most of it.
The hierarchy of GCP is broken into the following structure:
Organizations
Folders
Projects
Resources
Organizations
The Organization resource is the root node of the Google Cloud resource hierarchy and all resources that belong to an organization are grouped under the organization node.
The Organization resource is associated with a Google Workspace or Cloud Identity account.
The Google Workspace super admin is the individual responsible for domain ownership verification and the contact in cases of recovery.
Folders are also introduced when you use Cloud IAM.
The Cloud IAM Folders feature lets you assign policies to resources at a level of granularity you choose.
The resources in a folder can share IAM policies
Google Cloud IAM is comparable to AWS Directory Service.
Pricing/Cost Estimating
Select your product and estimate will appear for usage.
A Cloud Billing account is set up in Google Cloud and is used to define who pays for a given set of Google Cloud resources and Google Maps Platform APIs.
A Cloud Billing account is a cloud-level resource managed in the Cloud Console.
Billing Model
Two types of billing accounts
1.Self Serve– Online - Payment instrument is a credit or debit card or ACH direct debit
2.Invoiced – Offline – Payment can be check or wire.
Two types of payment profiles
1.Individual
2.Business
Charging Cycles
Self-serve Cloud Billing accounts, your Google Cloud costs are charged automatically in one of two ways:
1.Monthly billing: Costs are charged on a regular monthly cycle.
2.Threshold billing: Costs are charged when your account has accrued a specific amount.
Per-second billing, sustained use discounts
1 minute minimum and 1 sec increments
Preemptible instances
Live at most 24 hours
Can be pre-empted with a 30 second notification via API
Discounted significantly
VM vCPU and memory usage for each of these categories can receive one of the following discounts:
Sustained use discounts
Committed use discounts
Discounts for preemptible VM instances
Discount Model – Sustained Use
Sustained use discounts are applied on incremental use after you reach certain usage thresholds.
This means that you pay only for the number of minutes that you use an instance.
GCP automatically gives you the best price.
Discount Model – Committed Use
Committed use discounts are very useful for workloads with predictable resource needs.
When you purchase a committed use contract, you purchase compute resources at a discounted price.
Committed use discounts apply to both vCPUs and memory.
Commitment for 1 year or 3 years
Discount Model – Capacity Reservations
Reserved capacity is decoupled from reservations
When you purchase Committed Use Discounts, it’s not guaranteed you can launch an instance in the specified region or configuration.
For a guarantee purchase a zonal reservation.
Inferred instances- for billing purposes, the same type of machine used in the same zone will be combined into a single charge (increases your discounts)
Discount applied to custom machines as well
Test Tips
Exam had several questions on discount models. Scenario based.
Charging cycle for self serve accounts are threshold or monthly.
Committed use discounts are very useful for workloads with predictable resource needs.
GCP provides compliance capabilities around these categories
Certifications / attestations / reports
Alignments / frameworks
Laws / regulations
GCP provides three main compliance resource webpages

A. Cloud Armor B. Binary Authorization C. Cloud Security Scanner D. Forseti Security
Explanation: Web Security Scanner identifies security vulnerabilities in your App Engine, Google Kubernetes Engine (GKE), and Compute Engine web applications. It crawls your application, following all links within the scope of your starting URLs, and attempts to exercise as many user inputs and event handlers as possible.
Currently, Web Security Scanner only supports public URLs and IPs that aren’t behind a firewall. Web Security Scanner currently supports the App Engine standard environment and App Engine flexible environments, Compute Engine instances, and GKE resources.
5. Which of the following statements describe the features of a preemptible VM instance? (Select Three)
A. Instance is alive for no more than 24 hours B. Instance is alive for no more than 12 hours C Discounted Significantly D. Can use free tier credits E. Can be pre-empted with a 30 second notice F. Can be pre-empted with a 30 minute notice
Correct Answer(s): A, C, E. Instance is alive for no more than 24 hours, Discounted Significantly, Can be pre-empted with a 30 second notice.
Explanation: Preemptible VM is an instance that you can create and run at a lower cost than normal instances.
However, Compute Engine might stop (pre-empt) these instances if it requires access to those resources for other tasks. Preemptible instances are excess Compute Engine capacity, so their availability varies with usage.

11. Which of the following NIST Cloud characteristics uses the business model of shared resources in a cloud environment? (Select One)
A. Broad Network Access
B. Elasticity
C. Availability
D. Multi-Tenancy
Correct Answer(s): D. Multi-Tenancy
Explanation. In cloud computing, multitenancy means that multiple customers of a cloud vendor are using the same computing resources. Even though they share resources, cloud customers aren’t aware of each other, and their data is kept totally separate. Multitenancy is a crucial component of cloud computing; without it, cloud services would be far less practical. Multitenant architecture is a feature in many types of public cloud computing, including IaaS, PaaS, SaaS, containers, and serverless computing.
12. A customer has contacted you about migrating to Google Cloud. The customer would like to migrate their data from on premises as soon as possible. They don’t have the budget to rewrite code, and they want the most direct route. What migration option should suggest to the customer? (Select One)
A. Lift and Shift
B. Improve and Move
C. Rip and Replace
D. None, since the customer is not cloud native ready.
Correct Answer(s): A. Lift and Shift
Explanation. With Lift and Shift migrations, the customer could move workloads from a source environment to a target environment with few or no modifications or refactoring.
13. What load balancer type is supported with Cloud Armor security policies? (Select One)
A. Regional SSL
B. HTTP(S) Only
C. HTTP(S) and SSL
D. SSL Proxy, HTTP(S) and SSL
Correct Answer(s): B: HTTP(S) Only
Explanation. Google Cloud Armor security policies protect your application by providing Layer 7 filtering and by scrubbing incoming requests for common web attacks or other Layer 7 attributes to potentially block traffic before it reaches your load balanced backend services or backend buckets. Each security policy is made up of a set of rules that filter traffic based on conditions such as an incoming request’s IP address, IP range, region code, or request headers.
Google Cloud Armor security policies are available only for backend services behind an external HTTP(S) load balancer. The load balancer can be in Premium Tier or Standard Tier.
Google Cloud Armor security policies and IP DENY lists and ALLOW lists are available only for HTTP(S) load balancing.
Explanation. By default ,the limit is 5 per project. You can contact support to have this adjusted as needed. The exam has a few trivia around projects and quotas.
Explanation: Compute Engine provides machine type recommendations to help you optimize the resource utilization of your virtual machine (VM) instances. These recommendations are generated automatically based on system metrics gathered by the Cloud Monitoring service over the previous 8 days. Use these recommendations to resize your instance’s machine type to use the instance’s resources more efficiently. This feature is also known as rightsizing recommendations

Correct Answer(s): A, B, E. Classification. De-classification and Inspection
Explanation: Classification is the process to inspect the data and know what data we have, how sensitive it is, and the likelihood. Inspection and classification happen here.
De-identification is the process of removing, masking, replacing information from data.
18. What service is a fully managed real-time messaging service that allows you to send and receive messages between independent applications. (Select One)
A. Cloud Pub-Sub
B. Cloud BigTable
C. Cloud Spanner
D. Cloud DNS
E. Cloud Datastore
Correct Answer(s): A. Cloud Pub/Sub
Explanation: Google Cloud Pub/Sub is a scalable, durable event ingestion and delivery system.
Pub/Sub allows services to communicate asynchronously, with latencies on the order of 100 milliseconds.
Pub/Sub is used for streaming analytics and data integration pipelines to ingest and distribute data. It is equally effective as messaging-oriented middleware for service integration or as a queue to parallelize tasks.
Pub/Sub enables you to create systems of event producers and consumers, called publishers and subscribers. Publishers communicate with subscribers asynchronously by broadcasting events, rather than by synchronous remote procedure calls (RPCs).https://cloud.google.com/pubsub/docs/overview
