Most Common Interview Questions on Google Cloud
To give you a sense of what you can expect during a Google cloud interview, here are the top 10 commonly asked Google cloud interview questions and answers. Bear in mind that these questions are based on the experiences of past candidates and recruiters. It is only an indicative list that you can refer to while preparing for your interview.
1. What is a cloud?
A cloud can be defined as a combination of network, hardware, storage, and interface. This combination is responsible for delivering cloud computing as a service to its users across the globe. Companies primarily use cloud computing for fulfilling the requirements of various stakeholders. Every cloud computing system has two major participants -- the service provider who is responsible for setting up and managing the cloud services and the end-user who uses cloud services for a host of reasons.
2. Tell us about the various layers of Google Cloud.
There are four layers of the Google cloud platform:
- Infrastructure as a Service (IaaS): This is the basic layer that consists of hardware and network.
- Platform as a Service (PaaS): This is the second layer that provides the necessary resources for building applications along with the infrastructure.
- Software as a Service (SaaS): Saas is the third layer that allows the user to access the various cloud offerings from the service provider.
- Business Process Outsourcing: This is the final layer even though BPO is not a technical solution. BPO is concerned with outsourcing services to a vendor to take care of any issues faced by the end-user while using the cloud computing services.
3. Can you list out the major features of the Google Cloud Platform?
The key features include:
- Ability to create custom machine types where you can vary the CPU, memory, and storage.
- Resizing the disk in-pace can be carried out without any downtime.
- GCP has various pre-installed tools that can be used for controlling different processes.
- There are two hosting options. Users can either opt for App Engine, which is Platform as a Service, or Compute Engine, which is Infrastructure as a Service.
4. What are the different development models of cloud computing?
- Public cloud: Anyone can access a public cloud as the service is available via a subscription. Accessible resources of such a cloud include OS, CPU, memory, and storage.
- Private cloud: Such a cloud can only be accessed by a single organization and its employees. It is also known as internal cloud or corporate cloud.
- Hybrid cloud: A combination of public and private clouds creates a hybrid cloud. It consists of mixed computing, storage, and services environment and is popular with organizations looking for improved scalability and control.
- Community cloud: With a community cloud, several organizations can use the same service for sharing information.
5. What are the various Google Cloud storage services?
The common ones are:
- Google Workspace
- Cloud Storage (Object storage)
- Persistent disk
- Data Transfer Services
- Transfer Appliance
- Cloud Storage for Firebase
- Local SSD
- Cloud Storage (Archival storage)
6. What is the use of bucket in Google Cloud Storage?
Buckets can be defined as basic containers used for storing data. Anything that you store on Cloud Storage must be stored in a bucket. There is no limit on the creation or deletion of the buckets. However, unlike directories and files, buckets cannot be nested.
7. What is Google Cloud Messaging?
It is a mobile notification service that allows third-party application developers to send notification data from developer-run servers to applications. It has been deactivated since April 2018 and replaced by Firebase Cloud Messaging.
8. How does cloud computing help to save costs?
Cloud computing doesn’t involve too many human resources. It also works based on pooling different resources where users only pay for what they use.
9. What is the relationship between Google Compute Engine and Google App Engine?
Google Compute Engine is the IaaS product, while Google App Engine is a PaaS product. They are complementary to each other. The App Engine is used for running web-based applications and mobile backends, while you can use Compute Engine for implementing any customized business logic or even run your own storage system.
10. What do you know about Google Cloud APIs?
The primary use of APIs is to automate the workflow through your preferred language. APIs enable communication with various Google services and also facilitate their integration to other services. It can also be defined as a gateway that allows access to direct and indirect cloud infrastructure and various software services to end-users.
