Study Notes

Cloud Spanner vs Traditional Databases

Cloud Spanner is distinguished from traditional relational databases by its capacity for globally distributed data with horizontal scalability.
This allows for seamless data management across geographically dispersed locations while seamlessly scaling infrastructure to handle increasing data volumes.

Cloud Bigtable Data Model

Cloud Bigtable utilizes a wide-column data model.
This model enables flexible storage of large, semi-structured datasets organized into rows, columns, and timestamps.

Data Consistency in Google Cloud Datastore

The consistency model employed by Google Cloud Datastore and relational databases is determined by application configuration, not a predefined default.

RESTful API Status Codes

A successful resource creation within a RESTful API is indicated by the HTTP status code 201 (Created).

Google Cloud Endpoints

Google Cloud Endpoints serve as a fully managed service for streamlining the process of creating, deploying, and managing APIs.
This empowers developers to build and manage robust API solutions efficiently.

Managed Messaging Services and Real-time Events

Managed messaging services excel at processing and routing real-time events.
This makes them indispensable for applications that necessitate rapid event handling and distribution.

Cloud Pub/Sub Capabilities

Cloud Pub/Sub is not a software application collecting user data nor does it directly exchange data between the publisher and subscriber.
It acts as a robust, scalable messaging platform.

Cloud Pub/Sub in Big-data Processing

Cloud Pub/Sub plays a crucial role in the ingesting phase of a big-data processing model.
It effectively handles the inflow of data from various sources, facilitating efficient processing of large datasets.

Google Cloud IAM: User Identity and Access Management

Google Cloud IAM is responsible for managing user identities and access permissions to Google Cloud resources.
This centralized service ensures secure access control for all users within the Google Cloud environment.

Customer-Supplied Encryption Keys (CSEK)

CSEK in Google Cloud enables customers to provide their own encryption keys to secure data stored within the platform.
This gives users greater control over the encryption process and enhances data security.

Google Cloud Data Encryption Standard

Google Cloud uses the AES-128 encryption standard for data at rest, ensuring robust protection of data stored within their services.

CMEK: Customer Managed Encryption Keys

CMEK stands for Customer Managed Encryption Keys.
This option allows customers to retain ownership and control over their encryption keys, enhancing data security and compliance.

Google Cloud Identity and GSuite Integration

Cloud Identity seamlessly integrates with GSuite, streamlining user identity and access management for organizations utilizing both services.
This centralized solution simplifies user management and facilitates secure collaboration.

Network Subnet Calculation

A host with the address 172.16.45.14/30 belongs to the subnetwork 172.16.45.12.
The /30 subnet mask indicates that only the last two bits are available for host addresses, resulting in a subnet containing four addresses.

Auto Subnet Mode in Google Cloud

In auto subnet mode, the range of addresses is expandable up to /16.
Custom subnets have predefined IP ranges, offering greater flexibility and control over address allocation.

Routing Algorithm Types

Routing algorithms can be broadly classified into three types:
- Non-adaptive algorithms: They do not adjust to network changes.
- Adaptive algorithms: They dynamically adapt to changing network conditions.
- Hybrid algorithms: They combine aspects of both non-adaptive and adaptive algorithms.

Packet Filtering Firewalls and Spoofing

Packet filtering firewalls are vulnerable to spoofing attacks.
Spoofing involves manipulating the source address of network traffic, potentially allowing malicious actors to bypass security measures.
