Some of the important security aspects that the cloud offers are as below:

• Access control: it offers control to the users who can control the access to other users who are entering the cloud ecosystem
• Identity management: this provides the authorization for the application services
• Authorization and authentication: this security feature lets only the authenticated and authorized users access the applications and data.

11. What are system integrators in Cloud Computing?

The cloud can consist of multiple components that can be complex. The system integrator in the cloud is the strategy that provides the process of designing the cloud, integrating the various components for creating a hybrid or a private cloud network among other things.

12. What are the various components of the Google Cloud Platform?

The various GCP components are:

• Google Compute Engine
• Google Cloud Container Engine
• Google Cloud Storage

• Google Cloud Endpoints
• Google Cloud Test Lab

13. What are the main advantages of using Google Cloud Platform?

Google Cloud Platform is gaining popularity among cloud professionals as well as users for the advantages they offer over others :

• GCP offers competitive pricing 
• Google Cloud servers allow access to information from anywhere 
• GCP has an overall better performance and service compared to other hosting cloud services
• Google Cloud provides speedy and efficient server and security updates
• The security level of Google Cloud Platform is exemplary; the cloud platform and networks are secured and encrypted with various security measure

14. How does cloud computing provide on-demand functionality?

As a technology, cloud computing was built on the foundation of providing functionality to all its users on-demand at any time and from anywhere. With the latest advancements and easy availability of applications like Google Cloud, it has achieved that goal.

A user on Google Cloud can view the files on the cloud on any device at any time from wherever they are as long as they are connected to the internet.

15. What are the various layers in the cloud architecture?

The different layers that constitute the cloud architecture are:

• Physical layer: This constitutes the physical servers, network, and other aspects
• Infrastructure layer: This layer includes storage, virtualized layers, and so on
• Platform layer: This includes the operating system, apps, and other aspects
• Application layer: This is the layer that the end-user directly interacts with.

16. What are the libraries and tools for cloud storage on GCP?

JSON API and XML API are at the core level for the cloud storage on Google Cloud Platform. But along with these, Google also provides the following to interact with the cloud storage.

• Google Cloud Platform Console to perform basic operations on objects and buckets
• Cloud Storage Client Libraries that provides programming support for various languages 
• Gsutil Command-line Tool provides a CLI for the cloud storage

There are also a number of third-party libraries and tools like Boto Library.

17. What is “EUCALYPTUS” in the context of cloud computing?

“EUCALYPTUS” stands for “Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems”, which is an open-source cloud computing infrastructure that is used for deploying cloud clusters. Using the “EUCALYPTUS”, you can build public, private, and hybrid cloud platforms. You can even have your own data center in the cloud and this can be used to harness its functionality in your organization.

18. What is Google Compute Engine?

Google Cloud Engine is the basic component of the Google Cloud Platform. It is an IaaS that provides flexible Windows and Linux-based virtual machines that are self-managed and hosted on the Google infrastructure. The virtual machines can run on local, durable storage options, and KVM.

For the purpose of control and configuration, Google Cloud Engine also includes REST-based API. It integrates with other GCP technologies (Google Cloud Storage, Google App Engine, Google BigQuery, etc.) that help extend its computational ability thus creating more complex and sophisticated applications.

19. What are the different methods for the authentication of Google Compute Engine API?

There are different methods for the authentication of Google Compute Engine API. They are:

• Through client library
• Using OAuth 2.0
