Q

What is Firebase?

A

Google’s mobile development platform that shares 3 products with GCP:

Cloud Firestore, Cloud Functions, and Cloud Storage

17
Q

What is Cloud Datastore

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A
  • Type: NoSQL document
  • Transactions: Yes
  • Complex queries: No
  • Capacity: TB+
  • Unit Size: 1 MB per entity
18
Q

What is Bigtable

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A

Cloud Bigtable stores data in a file system called Colossus, which contains
data structures called Tablets that are used to identify and manage the data. Metadata about the Tablets is what is stored on the VMs in the Bigtable cluster itself.

  • Type: NoSQL wide column
  • Transactions: Single-Row
  • Complex queries: No
  • Capacity: PB+
  • Unit Size: ~10 MB/Cell; ~100 MB/Row
19
Q

What is Cloud Storage

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A
  • Type: Blobstore
  • Transactions: No
  • Complex queries: No
  • Capacity: PB+
  • Unit Size: 5 TB/object
20
Q

What is Cloud SQL

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A
  • Type: Relational SQL for OLTP (Transactions)
  • Transactions: Yes
  • Complex queries: Yes
  • Capacity: TB+
  • Unit Size: Determined by DB Engine
21
Q

What is Cloud Spanner

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A
  • Type: Relational SQL for OLTP (transactions)
  • Transactions: Yes
  • Complex queries: Yes
  • Capacity: PB
  • Unit Size: 10,240 MiB/Row
22
Q

What is BigQuery

(Type/Transactions/Complex Queries/Capacity/Unit Size)

A
  • Type: Relational SQL for OLAP (Analytics)
  • Transactions: No
  • Complex queries: Yes
  • Capacity: PB+
  • Unit Size: 10 MB/row
23
Q

What is ACID?

A
  • Atomic - a transaction is all or nothing
  • Consistent - a transaction meets all requirements/validation rules
  • Isolated - a transaction will not affect, or be affected, by other transactions
  • Durability - a transaction that completed is persistent even under failure conditions
24
Q

What is BASE?

A
  • Basically Available - The database appears to work most of the time
  • Soft-state - data stores and replicas do not have to be write-consistent
  • Eventual consistency - data stores and replicas will eventually be consistent
25
Q

What are the 4 Cloud Storage Classes

A
  • Standard
  • Nearline
  • Coldline
  • Archive
26
Q

Storage Class Use case:

Access data frequently (“hot” data) and/or store data for brief periods

  • Serve Website content
  • Stream videos
  • Interactive workloads
  • Mobile and gaming apps
A

In this scenario, Standard Storage would be best

27
Q

Storage Class Use case:

Read/modify data ≤ once per month

  • Data backup
  • Serve long-tail multimedia content
A

Nearline storage would work well here. It has a minimum duration of 30 days.

28
Q

Storage Class Use case:

Read/modify data no more than once a quarter

A

Coldline storage: 90 day minimum duration

29
Q

Storage Class Use case:

Read/modify data < once a year

  • Cold data storage
  • Disaster recovery
A

Archive Storage with a minimum duration of 365 days
