What is GCP ?

GCP stands for Google Cloud Platform which is a suite of public cloud computing services offered by Google. It offers 4 main kinds of services: compute, storage, big data, machine learning that run on Google hardware.

what is cloud computing ?

  • On-demand self-service: use interface to get processing, no human intervention needed
  • Broad network access: access from anywhere
  • Resource pooling: provider shares resources to customers
  • Rapid elasticity: get more resources quickly as needed
  • Measured service: pay only for what you consume

compute evolution

  1. Physical/colo: user-configured, managed and maintained
  2. Virtualized: user-configured; provider-managed and maintained
  3. Serverless: container based architecture, fully automated

gcp computing architectures

  • IaaS: Infrastructure as a Service
    • provides raw compute, storage and network organized in ways that are like from data centers
  • PaaS: Platform as a Service
    • provides a platform allowing customers to develop, run and manage applications without maintaining infrastructure
  • SaaS: Software as a Service
    • software is licensed on a subscription basis and is centrally hosted

regions and zones

GCP is organized into regions and zones. Zone is department area for GCP resources. For example, the compute engine runs in a zone specified.

Locations within regions usually have network latencies of under 5 milliseconds

As of building a fault tolerant application, you can spread their resources across multiple regions

open apis

GCP services are compatible with open sources products. for example:

  • Cloud Bigtable <==> Apache HBase
  • Cloud Dataproc <==> Hadoop

gcp services

GCP offers services as compute, storage, big data and machine learning

budgets and billing

GCP provides 4 tools to help:

budgets and alert: define budget per billing or per project, you can create an alert at 50 percent, 90 percent and 100 percent

billing: you have billing account on GCP project

export: store detailed billing information

reports and quotas:

  • report is a visual tool to monitor your expenditure.
  • quotas are designed to prevent over-consumption of resources
    • rate quotas
      reset after a specific time. eg: Kubernetes service set a quota of 1000 calls per 100 seconds
    • allocation quotas
      govern the number of resources you can have in your projects. eg: no more than 5 VPN per project
