16. What are the different kinds of software as a service (SaaS)?

The two different types of Saas are:

  1. Single-tenant multi-tenancy: This SaaS model gives you access to dedicated resources that you aren't required to share with anyone else.
  2. Multi-tenancy of fine grain: Resources are shared among multiple tenants in this SaaS deployment even though the functionalities are unchanged.

17. What is the benefit of API in the cloud domain?

  • You don't need to make the whole program.
  • You can easily send information from one app to another.
  • It's easy to make apps and connect them to cloud services.
  • It connects two applications safely.

18. Explain the difference between scalability and elasticity in cloud computing?

  • Scalability: The ability to handle more workload in the cloud is known as scalability. It can be accomplished by adding more servers or making room for them within existing ones.
  • Elasticity: Elasticity is the capability of adding or removing virtual machines on demand, allowing you to optimize resource usage and reduce costs.

19. What are service accounts?

Service accounts are project-related special accounts. They are used to authorize Google Compute Engine to perform tasks on behalf of the user, granting access to non-sensitive data.

20. What is your familiarity with Google Cloud SDK?

The Google Cloud Software Development Kit (SDK) provides developers with a set of utilities for working with Google Cloud Platform-based services and data. It comprises three separate command line utilities: gcloud, gsutil, and BQ command. The Google Cloud SDK is only compatible with particular OS and versions of Python (2.7.x), such as Windows, Linux, and macOS. There may be other, more specific requirements for the other tools in the set.

21. List major components of the Google Cloud Platform?

Some significant components of GCP are:

  • Tools for processing data, including Google's App Engine and the Kubernetes container orchestration system.
  • Various networking-related parts, including Virtual Private Clouds (VPCs), Cloud Firewalls, and more.
  • There's a database and a storage system.
  • Substances of Big Data.
  • Tools for management, including a tracer, logger, and debugger.
  • Software for managing one's identity in the cloud, including Cloud IAM and Cloud Identity.
  • Efficiency and expert apparatuses.

23. How does the cloud provide on-demand functionality?

Cloud computing was made as a technology so all its users could use it whenever and wherever they wanted. With the latest tech and easy access to apps like Google Cloud, the idea is much easier to implement than it used to be. With Google Cloud and other similar apps, users can access their cloud-stored files from any device, anytime, or anywhere in the world.

24. What is the pricing model in the GCP cloud?

You only pay for the resources you actually use in GCP due to its pay-as-you-go pricing model. No money or commitment is needed right away. In addition, a budget can be made to assist in managing expenses.

25. What are the GCP cloud storage libraries and tools?

Cloud storage on Google's cloud platform relies heavily on the JSON API and the XML API. Additionally, Google also offers the following to engage with cloud storage.

  • The Google Cloud Platform Console can perform basic operations on buckets and objects.
  • Client libraries for cloud storage that are available in various languages.
  • The Gsutil Command-line Tool is a command-line interface (CLI) for cloud storage.

26. What do you think "Managed VMs" means when it comes to GCP?

Google managed VMs, or virtual machines, in this context. Google takes care of the infrastructure, including the host operating system, virtualization layer, and hardware, when you launch a virtual machine on GCP using Managed VMs. It can simplify your workflow and allow you to concentrate on developing and deploying applications.

27. What's the difference between PaaS and IaaS? 

  • IaaS: IaaS, which stands for "Infrastructure as a Service," is a type of cloud computing that lets users access a virtualized computing environment. This can include storage, networking, and servers, among other things.
  • Paas: PaaS, which stands for “Platform as a Service.” is a type of cloud computing that gives users access to a platform for testing, building, and deploying applications. PaaS can make it easier to build and deploy apps because it takes care of much of the infrastructure behind them.

28. What is autoscaling in GCP?

Auto-scaling is possible with the Google Cloud Platform's managed instance groups. Managed instance groups are collections of identical instances that were created from the same master template. The easiest way to auto-scale in Avi Vantage is to scale based on how much CPU a group of virtual machine instances uses.

29. What is the use of a bucket in Google Cloud Storage?

Buckets are simple containers that are used to store data. Everything you put in Cloud Storage must be in a "bucket." There is no limit on how many buckets you can make or delete. But buckets can't be put inside each other as directories and files can.

30. What is meant by Google Cloud APIs?

Google Cloud APIs are most useful when used to automate processes in a language of your choosing. With the help of APIs, multiple Google services can talk to one another and be incorporated into third-party applications. Another way to think of it is as an intermediary through which end users can access cloud-based resources and applications.

31. What are the connections between Google Compute Engine and Google App Engine?

Google Compute Engine is Google's product for providing IaaS (infrastructure as a service). Google App Engine, on the other hand, is Google's PaaS offering in the category of platform services. They are a great pair and complete each other. Compute Engine creates custom business logic, while App Engine is used to power websites and mobile backends. It can even serve as the host for a private data storage system.

Most Common GCP FAQs

1. What is binary authorization in Google Cloud?

Cloud Run and GKE (Google Kubernetes Engine) use binary authorization to ensure that only trusted container images are used. You can use Binary Authorization to ensure that only trusted authorities sign images. At the same time, they are being built to ensure that signature validation is done when deployed.

2. What do you mean by Google Kubernetes?

You can use Google's infrastructure to deploy, manage, and scale containerized applications with the help of Google Kubernetes Engine (GKE). A cluster of computers (Google Compute Engine instances) makes up the GKE environment.

3. What is Google Cloud Vertex AI?

With Vertex AI, you get a unified set of client libraries, APIs, and graphical user interfaces for AutoML and AI Platform. Users of Vertex AI have access to AutoML and can tailor their training to their specific needs. Vertex AI allows you to train models in any way you like, then store, deploy, and request predictions from those models. Using pre-trained and custom tools on a unified AI platform can hasten the processes of deploying, creating, and scaling machine learning models.

4. What kinds of databases are compatible with GCP?

MySQL, PostgreSQL, MongoDB, and BigTable are just a few database systems that can be used with GCP.

5. What does BigQuery mean?

The Google Cloud Platform provides a service called BigQuery, which serves as a warehouse for large businesses. The product has an in-memory data analysis engine and machine learning capabilities, making it highly scalable and affordable. You can quickly and easily perform real-time data analysis and generate insightful reports using a data analytics engine. It's not just internal data that BigQuery can analyze; it can also process data from external sources like object storage, transactional databases, and spreadsheets.
