Cloud Datastore
horizontally scalable NoSQL DB, designed for application backends, fully managed, uses a distributed architecture to automatically manage scaling, built-in redundancy, supports ACID transactions
Regional cloud storage classes
intended for data that is accessed frequently within a region, availability SLA 99.90%, 2nd highest storage price, 2nd lowest retrieval cost, use case- in region analytics, transcoding lets you store your data in a specific GCP region, us-central1, europe-west1 or asia-east1. It's cheaper than multi-regional storage, but it offers less redundancy.
Multi-regional cloud storage classes
intended for data that is most frequently accessed, availability SLA 99.95%, Highest Storage price, Lowest Retrieval price, use cases- content storage and delivery costs a bit more, but it's geo-redundant. That means you pick a broad geographical location, like United States, the European Union, or Asia, and Cloud Storage stores your data in at least two geographic locations separated by at least 160 kilometers.

four ways to interact with gcp

Cloud SQL
easy to use service that delivers fully managed relational database, includes network firewall, allowing you to control network access to your databse instance by granting access, scale up to 64 processor cores, 100 GB of RAM
Autoscaling
lets you add and take away VMs from your application based on load metrics. The other part of making that work is balancing the incoming traffic among the VMs. And Google VPC supports several different kinds of load balancing
Cloud Bigtable
managed NoSQL, a fully managed service, which means that you spend your time developing valuable applications instead of configuring and tuning your database for performance and scalability. In addition, Google's own Bigtable operations team monitors the service to ensure that issues are addressed quickly. Cloud Bigtable is ideal for applications that need very high throughput and scalability for non-structured key/value data, where each value is typically no larger than 10 MB. Cloud Bigtable also excels as a storage engine for batch MapReduce operations, stream processing/analytics, and machine-learning applications.

global distributed firewall you can control to restrict access to instances, both incoming and outgoing traffic. You can define firewall rules in terms of metadata tags on Compute Engine instances, which is really convenient. For example, you can tag all your web servers with, say, "WEB," and write a firewall rule saying that traffic on ports 80 or 443 is allowed into all VMs with the "WEB" tag, no matter what their IP address happens to be

Why would a customer consider the Coldline storage class?
To save money on storing infrequently accessed data.
Coldline Cloud Storage Classes
Intended for data that is accessed less than once a year, availability SLA 99.00%, Lowest storage cost, highest retrieval price, use case- archiving disaster recovery is a very-low-cost, highly durable storage service for data archiving, online backup, and disaster recovery. Coldline Storage is the best choice for data that you plan to access at most once a year, due to its slightly lower availability, 90-day minimum storage duration, costs for data access, and higher per-operation costs. For example, if you want to archive data or have access in the event of a disaster recovery event.
Cloud Datastore benefits
Atomic transactions Datastore can execute a set of operations where either all succeed, or none occur. ● High availability of reads and writes Datastore runs in Google data centers, which use redundancy to minimize impact from points of failure. ● Massive scalability with high performance Datastore uses a distributed architecture to automatically manage scaling. Datastore uses a mix of indexes and query constraints so your queries scale with the size of your result set, not the size of your data set. ● Flexible storage and querying of data Datastore maps naturally to object-oriented and scripting languages and is exposed to applications through multiple clients. It also provides a SQL-like query language. ● Balance of strong and eventual consistency Datastore ensures that entity lookups and ancestor queries always receive strongly consistent data. All other queries are eventually consistent. The consistency models allow your application to deliver a great user experience while handling large amounts of data and users. ● Encryption at rest Datastore automatically encrypts all data before it is written to disk and automatically decrypts the data when read by an authorized user. For more information, see Server-Side Encryption. ● Fully managed with no planned downtime Google handles the administration of the Datastore service so you can focus on your application. Your application can still use Datastore when the service receives a planned upgrade.
*True or False*: In Google Cloud IAM: if a policy applied at the project level gives you Owner permissions, your access to an individual resource in that project might be restricted to View permission if someone applies a more restrictive policy directly to that resource.
False
True or false: Google manages every aspect of Google Cloud Platform customers' security.
False
Nearline Cloud Storage Classes
Intended for data that is accessed less than once a month, availability SLA- 99.00%, 2nd lowest storage cost, 2nd highest retrieval price is a low-cost, highly durable storage service for storing infrequently accessed data. This storage class is a better choice than Multi-Regional Storage or Regional Storage in scenarios where you plan to read or modify your data on average once a month or less. For example, if you want to continuously add files to Cloud Storage and plan to access those files once a month for analysis, Nearline Storage is a great choice.
