    Study Notes

    Google Cloud Fundamentals: Core Infrastructure

    • Google Cloud provides instructor-led training on core infrastructure
    • The training covers cloud computing basics, Google Cloud's structure, and unique features
    • Cloud computing is a way of using information technology with five equally important traits.

    What is Cloud Computing?

    • The term "cloud computing" was coined by the US National Institute of Standards and Technology (NIST).
    • It's a way of using information technology (IT) that has five key traits.

    Five Equally Important Traits of Cloud Computing

    • On-demand and self-service: Customers get computing resources easily and independently through a web interface
    • Access over the internet: Resources are accessible from anywhere via the internet.
    • Resource pooling: Providers allocate resources from a shared pool. Customers don't need to know the physical location.
    • Elasticity: Resources can be quickly scaled up or down as needed.
    • Pay-per-use: Customers pay only for the resources they use or reserve

    History of Cloud Computing

    • First wave: Colocation-users lease physical space in data centers.
    • Second wave: Virtualized data centers-virtualized components of private data centers.
    • Third wave: Container-based architecture-fully automated, scalable cloud based on services and data.

    Enterprises Still Maintain Infrastructure

    • Enterprises maintain their user-controlled and user-configured environment with virtualization.

    Google Cloud's Architecture: The Three Waves

    • The first wave of cloud computing was based on colocation. This was a simple model where businesses renting space in server racks.
    • The second wave of cloud computing brought virtualization, which allowed businesses to have virtualized servers in common data centers improving efficiency. The virtualization model is efficient.
    • The third wave of cloud computing introduced containers in order to provide a more scalable, efficient and faster cloud computing services.

    Third-Wave Cloud

    • Google makes this third-wave cloud available to customers.
    • Google believes that in the future all companies will differentiate themselves through technology in the form of software, based on high-quality data.

    Cloud Service Offerings

    • Infrastructure as a Service (IaaS): On-demand infrastructure resources, including raw compute, storage, and networking; Compute Engine is an example.
    • Platform as a Service (PaaS): Manages hardware and software; App Engine is an example that allows developers focus on application logic.

    Payment Models

    • IaaS: Users pay for allocated resources in advance.
    • PaaS: Users pay for actual resource use.

    The Evolution of Cloud Computing

    • From managed resources and services to serverless
    • Businesses concentrate on business goals through managed services.
    • Serverless technologies, like Cloud Run, manage infrastructure and services.

    Software as a Service (SaaS)

    • Provides a complete application stack. It is not installed on a local computer.
    • Examples: Gmail, Docs, and Drive from Google Workspace.

    Google Cloud Network

    • The largest network - involves billions of dollars in investment
    • Designed for high throughput and low latency.
    • Features content caching nodes across the globe.
    • Location of resources impacts factors such as availability, durability, and latency.

    Infrastructure Locations

    • Google Cloud’s infrastructure is based in North America, South America, Europe, Asia, and Australia
    • The locations affect qualities like: availability, and latency

    Geographic Locations

    • Locations are divided into regions and zones. Regions comprise multiple zones.
    • Each zone is an area where Google Cloud resources are deployed.

    Zones

    • Where resources are deployed (e.g., virtual machines).
    • Ensure resource redundancy.
    • Resources run in different regions to provide protection against issues with an entire region (e.g., natural disaster.)
    • Some services can run in multiple geographic locations. (e.g., using multiple locations for data replication.)

    Resources in Different Regions

    • Useful for bringing applications closer to users globally.
    • Offers protection against issues with individual regions, such as natural disasters
    • Google's cloud services are supported by 121 zones in 40 regions.

    Data Center Energy Consumption

    • Google Cloud's physical infrastructure uses a significant amount of energy.
    • It strives to make data centers as efficient as possible; Data centers in Finland with sea-water cooling are considered efficient.
    • Google aims to achieve 100% renewable energy use and be carbon-free by 2030.

    Google's Commitment to Sustainability

    • Data centers use up to 2% of the world’s electricity.
    • Became the first major company to achieve carbon neutrality.
    • First to achieve 100% renewable energy.
    • Aim to operate with zero carbon emissions by 2030.

    Google Cloud Security

    • Google Cloud is designed with security in mind, and these ideas are applied on several levels.
    • A design for security is prevalent throughout the infrastructure, impacting how Google Cloud and related services function.

    Hardware Level Security

    • Custom server boards, chips, and networking equipment. Optimized security.
    • Secure boot stack that encrypts all software.
    • Multi-layer physical security measures in data centers.

    Service Level Security

    • Encryption of inter-service communication. All traffic between data centers is encrypted.
    • Security measures are provided through Hardware and Software to protect against attacks.

    User Identity Level Security

    • Google's central identity service challenges users with additional information based on risk.
    • Employing secondary factors such as U2F (Universal 2nd Factor); this is designed to combat sophisticated threats.

    Storage Service Level Security

    • Encryption at rest using centrally managed keys.
    • Hardware encryption support in drives and SSDs.

    Internet Communication Level Security

    • Google Front End (GFE) ensures TLS connections use the correct certificates.
    • Protection against Denial of Service (DoS) attacks.

    Operational Security Level

    • Rules and machine intelligence identify potential incidents.

    • Insider risk reduction through active monitoring of employee activities.

    • Requirements to use U2F-compatible security keys for all employee accounts.

    • Two-party review of new code.

    • Vulnerability Rewards Program incentivizes security bug discoveries.

    Billing Tools

    • Budgets: Fixed limits or based on metrics to control spending.
    • Alerts: When costs approach the budget limit.
    • Reports: Visual tools for monitoring expenditure.
    • Quotas: Prevent over-consumption of resources due to errors or malicious activities

    Quotas

    • Two types of quotas: rate quotas and allocation quotas, applied at the project level.
