Zorluk: KolayPlanning Database Options and Persistent Disk Types

An architecture team is planning storage configurations for a web application deployed on Google Cloud Compute Engine. The solution requires: 1) A ultra-fast, temporary caching tier requiring sub-millisecond I/O latency where data loss during instance termination is acceptable. 2) A fully managed relational database service for handling transaction data. Which TWO storage solutions should the team select? (Select TWO)

  1. Local SSD attached to Compute Engine instances for the temporary caching tierCevap
  2. B
    Cloud Bigtable for the transactional database layer
  3. Cloud SQL instance for the transactional database layerCevap
  4. D
    Spot VM instances with standard persistent disks to host the transactional database

Cevap

Local SSD attached to Compute Engine instances for the temporary caching tier, and Cloud SQL instance for the transactional database layer.
Local SSDs are directly attached to the physical host running the Compute Engine instance, providing sub-millisecond latency for caching data where persistence across instance reboot/termination is not required. Cloud SQL is the recommended Google Cloud service for fully managed relational databases needing standard SQL capabilities and high availability.

Adım Adım Çözüm

1
Evaluate the requirements for the temporary caching tier.
Identify that sub-millisecond latency and ephemeral transient storage point directly to Local SSD.
Local SSDs are physically attached to the host server, offering maximum IOPS and lowest latency for temporary cache data.
2
Evaluate the requirements for the database tier.
Identify that a fully managed relational database engine aligns with Cloud SQL.
Cloud SQL provides managed MySQL, PostgreSQL, and SQL Server instances for relational OLTP workloads.
