This article is more than sufficient preparation and crack the google cloud associate certification exam. this post covers topics, exam question and dumps.
Difference between IAAS vs PASS
| IAAS infrastructure as a service | PASS : platform as service | SASS: Software As Service |
| Iaas offers Raw compute storage Netwrok capbilites | pass offering in contrast, bin code to libraries that provide access to the infrastructure that the application needs. This allow more resources to be focused on application logic. | software as a service applications are’nt installed on your local compute. instead, they run in the cloud as a service and are consumed directly over the internet by end users. eg. popular google applications such as gmail, docs, and drive, canava, online editing video audio editing softwares |
| pay | pay | pay |
| Pay for what they allocate. eg: compute machine we need to choose machine size, storage etc and pay for it | Pay for what they use (pay as you go service eg: cloud functions when we use it they only we need to pay. Cloud functions: Manage event-driven code as a pay-as-you-go Cloud Run: deploy containerised micro services based application in a fully-managed environment |
Google Cloud Network
Location > region >> zone
Each locations is divided into several different region and zones.
In the above example
Location is London, having
Region europe-west2, made up of three zones
zone: europe-west2-a, europe-west2-b, europe-west2-c.
NOTE: A zone is an area where google cloud resources are deployed. for example if you launch a virtual machine using compute engine, it will run in the zone that you specify.
some of Google Cloud services support placing resources in what we call a multi-region.
For example, Cloud spanner multi-region configurations allow you to replicate the database’s data not just in multiple zones. But in multiple zones across multiple regions, as defined by the instance configuration.
These additional replicas enable you to read data with low latency from multiple locations close to or within the regions in the configuration.
