What is Cloud Computing?

Cloud computing is characterized as computing power that is entirely stored in the Cloud at all times. It is among the most recent innovations in the internet saga domain, and it relies mainly on the Internet, i.e., the Cloud, for delivery. Moreover, the cloud computing service is entirely universal, with no geographic or boundary limitations.

About every organization in the world uses Google Cloud in some form, ranging from small companies that need computational help daily to huge companies.

What is the Cloud?

“Cloud” refers to servers that can access via the Internet and the applications and databases that run on them. Cloud servers are located in data centers located across the globe. As a result, businesses and consumers can avoid maintaining physical servers and running web applications on their machines using cloud computing.

Since the computing and storage occur on computers in a data center rather than directly on the individual computer, customers can find duplicate files and applications from nearly any device via the Cloud. It is why, even if a user’s old phone breaks, they can log into their Instagram account on a new phone and find their old account and all of their photographs, images, and chat history, also. In addition, it integrates for cloud email services like Gmail or Microsoft Office 365 and cloud storage services like Google drive.

Switching to cloud computing saves companies money by eliminating some IT costs and expenses. For example, they no longer have to update and manage their servers because the cloud vendor can do so for them. It has a significant effect on small companies who cannot afford their internal resources but can outsource their infrastructure requirements to the Cloud at a reasonable cost. Since employees and customers can access the same data and apps from any location, the Cloud makes it possible for businesses to work globally.

● Community 

● Private 

● Hybrid 

● Public 

Why is it essential for companies to manage their workload?

A workload in an enterprise may be described as a self-contained service with its collection of code that must execute. Everything from data-intensive workloads to transaction and storage processing is included in this workload. All of this work is independent of external factors.

The following are the essential reasons why businesses should manage their workload.

● An understanding of how the applications run. 

● To recognize the functions that take place.

● How much a specific department will charge for using such services.

Describe the Cloud Computing Revolution.

Cloud computing has brought in a revolution in the industry since its inception. The fundamental principle behind the cloud computing movement is to make the process easier and more potent in the long term, rather than only doing old things differently.

Cloud computing is opening up doors each day, and the IT industry’s future seems promising.

What does cloud computing do?

The potential of cloud computing is much more widespread than most people understand. The fact that technology is high-speed, along with the fact that consumers can immediately begin using it without having to buy something, are also strong indicators of a promising future.

For example, the medical and health industries are increasingly depending on cloud computing to meet and interact with customers at all times. As a result, it can be safely stated that cloud computing and its users will have various possibilities in the future.

Without using any magnetic disc, how can you long-term save your app’s software and drivers?

Discs or storage units have become unnecessary due to the innovation and advancements made in the Cloud Computing industry in recent years. Any data, in any format, can now be stored for an extended period by simply uploading it to a cloud computing service.

Until the user makes updates or changes to the data after uploading, it will remain there permanently. 

What is the on-demand functionality offered by cloud computing?

Cloud computing as technology was based on the principle of delivering features to all customers on-demand, at any time and any place. The concept is much easier to remember than before due to rapid developments and easily accessible apps like Google Cloud.

Users can view data on the Cloud on any computer at any time they choose, with the help of apps like Google Cloud.

What is Google Cloud Platform?

Google Cloud Platform is a Google-developed cloud network that allows users to access cloud systems and computing facilities. GCP provides a wide range of cloud computing services in the computing, database, storage, migration, and networking domains.

What is Google Compute Engine? 

Google Compute Engine is a tool of IaaS that provides Google’s infrastructure of self-managed and scalable virtual machines. It includes virtual machines based on Linux and Windows that can be run locally, via KVM, or on long-term storage.

For control and setup, it also provides a REST-based API. In addition, Google Compute Engine combines with Google Cloud technologies like Google App Engine, Google Cloud Storage, and Google BigQuery to expand its computing capabilities and create more advanced and complex applications.

How is the Google Compute Engine connected with Google App Engine?

Google App Engine is often used to run web-based apps, smartphone backends, and line-of-business applications. Compute Engine is an excellent choice if you need better control over the underlying infrastructure. Compute Engine, for example, can be used to apply customized business logic or run your storage system.

How does pricing model work in the GCP cloud?

Google Computing Engine charges users on Google Cloud Platform for computer, network use, and storage instances. For a minimum charge of one minute, Google Cloud charges a per-second virtual machine. The cost of storage is calculated by the amount of data you store.

The network cost is defined as the amount of data exchanged between virtual machines communicating across the network.

What are the service accounts? How will you create one?

Service Accounts are the individual accounts associated with a project. The service accounts are used to authorize Google Compute Engine to function on the user’s behalf and gain access to unauthorized information and data.

The accounts manage the authorization process by the user, which simplifies Google Cloud Engine’s authentication process to other services. However, it’s important to remember that service accounts aren’t used to access user information.

Google offers a variety of service accounts, but most people choose to use two types:

● Accounts for the Google Compute Engine service

● Service accounts with Google Cloud Platform Console

The customer is not required to build a service account manually. When a new instance is generated, the Compute Engine creates it automatically. When a Google Compute Engine instance is created, it also defines the extent of the service account for that instance.

Differentiate a Project Id and a Project Number?

The project Id and the project number are the two factors that are used to describe a project. They can be distinguished accordingly: if a new project is created, the project number is generated automatically, and the user manually generates the project number. For certain services, the project number is required, but the project Id is optional.

How you request more quota for your project?

For various categories of services, all Google Compute Engine projects are given specific default quotas. Quotas can also expand on a per-project basis. The Google Cloud Platform Console quota page can be used to review the quota limits for the project.

If you notice that you have reached the quota limit for your services and would like to expand it, you can use the IAM quotas website to request additional quotas for your resources. Using the Edit Quotas button at the top of the list, you will request more quota.

If you accidentally deleted your instance. Are you going to be able to get that back? 

It is not necessary to recover instances that have already been deleted. It can be retrieved if it is stopped by simply restarting it.

What is Google BigQuery? What are the benefits of BigQuery for data warehouse practitioners?

Google BigQuery is a software solution that replaces the traditional data warehouse’s hardware system. Therefore, it is a data warehouse and a centralized database for all analytical data in the organization. In addition, BigQuery divides the data table into units called datasets.

What is Google Cloud SDK?

The Google Cloud SDK (Software Development Kit) is a collection of tools for managing Google Cloud Platform apps and services. It is made up of the command line tools gsutil, gcloud, and bqcommand. With Cloud SDK, the gcloudtool is downloaded automatically.

There are basic requirements or system requirements for the installation of Google Cloud SDK. Google’s Cloud SDK operates on various platforms, including Windows, Linux, and macOS, including Python 2.7.x. Additional specifications can be found in some Google Cloud SDK software, such as Java apps for Google App Engine, including Java 1.7 or later.

What is the Google Cloud APIs? How can you access them?

Allow people to quickly and easily apply the power of anything to your Google Cloud-based application. Everything from database access to machine learning image analysis will benefit from APIs.

Google Cloud APIs Access

Cloud APIs from server applications are easily accessible for cloud libraries. To connect Google Cloud APIs, you can use various programming languages, mobile apps with Firebase SDKs, or third-party clients. Google Cloud APIs are also available via the Web Console UI and Google SDK command-line tools on the GCP.

What is VPC, In the GCP?

GCP’s Virtual Private Cloud (VPC) is a virtual network that connects the compute engine VM instances, GKE (Google Kubernetes Engine) clusters, and other tools. The VPC gives you a lot of power over how your workloads interact regionally or globally. For example, a single VPC can communicate through different regions instead of using the public Internet.

What are the benefits of API?

We don’t have to write code again if we use APIs that are already available, and we can implement applications in the Cloud.

What is integrator system in Cloud Computing?

The Cloud is complicated because it will have many components. The cloud system measurement system is a technique that explains how to create a cloud by desegregating the various components to create a hybrid or private cloud network, among many other things.

What’s a Google Cloud Storage Bucket?

Buckets are always the most basic containers for storing data. You should organize data and give control access to buckets. The bucket has a globally specific name that refers to the place where the contents are held. It also has a default storage class applied to objects added to the bucket without a storage class specified. There is an unlimited number of buckets to be generated or deleted.

What is Object Versioning in GCP?

Object versioning is a technique for retrieving items that have been overwritten or deleted. Object versioning raises storage costs while still ensuring object security as they are removed or overwritten. When you enable object versioning in your GCP bucket, every time the object is overwritten or deleted, a noncurrent version of the object is generated. The properties generation and meta generation is used to identify a variant of an entity. The term generation refers to creating content, while meta generation refers to the process of creating metadata.

What is Serverless computing?

In serverless computing, the cloud service provider operates a server in the Cloud that handles resource allocation dynamically. The service provider has the requisite infrastructure so that the user can run without worrying about the hardware. Users would account for the energy that they have used. It optimizes the code deployment process while also removing users’ concerns about scalability and maintenance. It is a utility computing form.

In cloud computing, what is load balancing?

The approach of sharing computational capabilities and workload to manage demand in a cloud computing environment is load balancing. It aids in achieving high efficiency at lower costs by effectively managing workload demands through resource allocation. It enables the use of scalability and agility to increase resource availability in response to demand. It’s also used to do wellness checks on the cloud app. All major cloud vendors, such as AWS, GCP, Azure, and others, have this feature.

What is google cloud messaging?

The free cross-platform notification solution (Android, iOS, Web) for sending and receiving messages and notifications is Firebase or Google Cloud Messaging. You will use this to send messages, notify client apps, and send messages to encourage user reengagement. In addition, it allows you to target your messages in various ways, like sending them to a single user, a group of devices, or subscribed devices.

What is the importance of a platform as a service?

PaaS is essential to cloud computing. But, first, you get an application layer that allows you to virtualize the infrastructure layer entirely and work on it as a single layer.

What is the Difference between Virtualization vs. Cloud Computing?

● Cloud Computing is a collection of layers that function together and provide IP-based computing; virtualization is a layer/module inside the Cloud computing architecture, enabling providers to deliver on-demand IaaS (Infrastructure as a Service).

● A virtualization is a form of computing that produces several “separated” representations of software and hardware on the same machine. It facilitates the installation of different operating systems, software, and applications on the same physical device.

Explain the Cloud Computing Drivers?

The pressure on businesses to be agile and cost-efficient has intensified due to globalization, a challenging economic climate, and the on-demand distribution model for customers. Cloud computing enables companies to expand and innovate. Cost, risk, and agility are the three main drivers of cloud computing.

Describe Public Cloud.

The most common and prominent cloud choice used by users is the public Cloud. IT infrastructure services such as compute, network, and storage are accessible reliably and cost-effectively in a public cloud system. Since many customers share these IT infrastructures, they are less expensive to use. A web browser is used to view and manage all of the services over the Internet. Three categories of public cloud services include SaaS, PaaS, and IaaS. Office 365, Salesforce, and other public cloud offerings are examples.

What is Hybrid Cloud?

It blends the advantages of public and private clouds to lower costs and distribute workloads according to business needs. Hybrid Cloud enables secure data transfer between private and public clouds. As a result, enterprise organizations benefit from increased flexibility and implementation options.

Describe the Advantages of Private Cloud.

Compared to the public Cloud, provide Cloud offers more flexible security solutions and functionality to satisfy the needs of internal users as the company grows. It can also be expanded or updated as needed.

What is a Private Cloud?

A private cloud contains a single enterprise or company’s computing resources. The private Cloud may be managed on-site at an organization’s data center or by a third-party service provider. Private cloud infrastructure and resources are also maintained in a private network, and the business is solely dedicated to software and hardware.

What is Cloud Armor?

It will help in the protection of the infrastructure and application from DDoS attacks. It protects the infrastructure by working with HTTPS load balancers. For the same, we may allow or deny the rule. Cloud Armor’s rules-language is modular, allowing for customization of defense and prevention of attacks. It also has predefined rules to protect against application-aware cross-site scripting (XSS) and SQL injection (SQLi) attacks. If you’re running a web server, the allow and deny rules you set up will help you defend against SQL injection, DDoS attacks, and other attacks.

How does Azure load balancer work?

On layer 4, the Azure load balancer distributes traffic through the VMS. There are two kinds of load balancers: internal load balancers for internal applications and external load balancers for external applications. If you have a web application running on a series of VMs and want to load balance it externally or internally, the Azure load balancer will help. You can customize the health prob and another rule for your web app. You can set up the same thing if you select to use NAT rules.
