Cloud Storage Flashcards
What type of storage offers the most solutions for cost efficency?
Cloud Storage
Which types of databases are considered No SQL?
Cloud DataStore, BigTable, Cloud Firestore
Which types of data bases are considered SQL?
Cloud SQL, Cloud Spanner
What is the max storage for Cloud SQL?
10 TB
What is the max storage for Cloud Spanner?
10 TB
What type of storage supports large amounts of No SQL data, and powers Google’s core services?
Bigtable
What SQL database offers both Stackdriver integration and failover/replica options?
Cloud SQL
What SQL database offers the highest SLA and is best for mission critical work?
Cloud Spanner
What is the lowest class of storage in Cloud Storage?
Archive; For data that needs to be accessed less than once a year
What storage class in Cloud Storage is best for disaster recovery?
Coldline; For data that needs to be accessed no mre than once a quarter (Lower price per GB but has a high retrieval cost)
What is the default storage setting for Cloud Storage buckets?
Standard; No mimimum time for storage, best for frequently accessed data
What is the default storage setting for Cloud Storage that is accessed multiple times per year but not often?
Nearline; lower storage costs but minimum for storage of at least 30 days and there is a price for retrieval
What storage service is best for ACID transactions and user profiles?
Cloud Datastore; is great for real time inventories
What storage service offers Global Time Stamps and provides external consistency?
Cloud Spanner; External consistency is the strongest available type of consistency which is good for transaction processing systems
How large is the storage capacity of BigTable?
Bigtable can scale to petabytes of data
What types of issues might you have with Bigtable?
Poor schema setup can greatly effect performance, but auto failover is available
Which No SQL database option has the ability to scale to zero?
Cloud Datastore
What service of Cloud Storage allows the retrieval of bects that have been deleted or overwritten?
Cloud Storage versioning; can be enabled to allow rollbacks on important files, does come with additional storage costs
What are primary considerations for transferring data into the Cloud?
The size of the data and the bandwidth you will need to do the transfer effectively (will need a high bandwidth for anything over 1TB of data)
Which Cloud Transfer Service allows us to transfer our online sources to a data sink?
Cloud Storage Transfer Service; Allows you to schedule data transfers, delete objects as nessasary, and can be set using gsutil
Which Cloud Transfer Service allows transfer of petabytes of data with little interruption to services?
Cloud Transfer Appliance; A hardware storage device that allows you to set up and upload in your data center and then send that device to Google where it is uploaded into Cloud Storage
What alternaives do you have for SQL database, other than Cloud SQL?
You can install a SQL server application onto a compute engine instance, but is then not managed by Google
What is the difference between SSD and HDD?
HDD is less expensive, but will be lower performing whereas SSD provides low latency and high throughput
Can you change the amount of storage in a SQL or compute instance?
You can increase the storage, but cannot decrease so it is important to make sure you know that before creating a new instance
