Cloud ready, cloud enabled, cloud based, cloud native application

همانطور که در تصویر مشاهده می‌کنید Cloud Ready هم راستا با مدل کلودی IaaS (زیر ساخت به عنوان سرویس) قرار دارد و نرم‌افزار در این مدل می‌تواند از امکانات ابری زیرساخت به عنوان سرویس استفاده کند. نرم افزار به سادگی در زیر ساخت‌های ابری مستقر و منتشر می‌شود در واقع تنها کافیست بدون تغییر در طراحی و پیاده‌سازی نرم افزار، اجرا روی تکنولوژی مجازی‌سازی به صورت ماشین مجازی را در نرم‌افزار ایجاد کرد که در این صورت قابلیت اجرا روی ابر مهیا می‌شود.

مدل Cloud Based (مبتنی بر ابر) که بین دو مدل Native (بومی) و Enabled (فعال) قرار دارد می‌تواند از امکانات مدل کلودی PaaS (پلتفرم به عنوان سرویس) استفاده کند، در مدل ابری پلتفرم به عنوان سرویس از ابزارهای قدرتمندی همچون کوبرنتیز استفاده شده‌است که به وسیله آن امکانات مختلفی به توسعه‌دهندگان ارائه شده است.

در مدل ابر بومی (Native) علاوه بر پلتفرم به عنوان سرویس نیز از نرم افزار به عنوان سرویس (SaaS) استفاده شده که حتی در این لایه ابری می‌توان نرم افزار‌های بومی به کاربران ارائه کرد

Solving problems aren’t easy, but solving the ones that can’t be seen by everybody is what makes a programmer. Best wishes to you on this Programmer’s Day😊🌹

Cloud Computing Interview Questions for Freshers
1. What is a Cloud Technology?
A cloud is a combination of services, networks, hardware, storage, and interfaces that helps in delivering computing as a service. It broadly has three users. These are the end-user, business management user, and cloud service, provider. The end-user is the one who uses the services provided by the cloud. The responsibility of the data and the services provided by the cloud is taken by the business management user in the cloud. The one who takes care of or is responsible for the maintenance of the IT assets of the cloud is the cloud service provider. The cloud acts as a common center for its users to fulfill their computing needs

2. What are some of the key features of Cloud Computing?
The following are some of the key features of cloud computing:
Agility: Helps in quick and inexpensive re-provisioning of resources.
Location Independence: This means that the resources can be accessed from everywhere.
Multi-Tenancy: The resources are shared amongst a large group of users.
Reliability: Resources and computation can be dependable for accessibility.
Scalability: Dynamic provisioning of data helps in scaling

3. What do you mean by cloud delivery models?
Cloud delivery models are models that represent the computing environments. These are as follows:
Infrastructure as a Service (IaaS): Infrastructure as a Service (IaaS) is the delivery of services, including an operating system, storage, networking, and various utility software elements, on a request basis. 
Platform as a Service (PaaS): Platform as a Service (PaaS) is a mechanism for combining Infrastructure as a Service with an abstracted set of middleware services, software development, and deployment tools. These allow the organization to have a consistent way to create and deploy applications on a cloud or on-premises environment.
Software as a Service (SaaS): Software as a Service (SaaS) is a business application created and hosted by a provider in a multi-tenant model. 
Function as a Service (FaaS): Function as a Service (FaaS) gives a platform for customers to build, manage and run app functionalities without the difficulty of maintaining infrastructure. One can thus achieve a "serverless" architecture

4. What are the different versions of the cloud?
There are two primary deployment models of the cloud: Public and Private. 
Public  Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by a third party for use by other companies or individuals is the public cloud. These commercial providers create a highly scalable data center that hides the details of the underlying infrastructure from the consumer. Public clouds are viable because they offer many options for computing, storage, and a rich set of other services.
Private Cloud: The set of hardware, networking, storage, services, applications, and interfaces owned and operated by an organization for the use of its employees, partners, or customers is the private cloud. This can be created and managed by a third party for the exclusive use of one enterprise. The private cloud is a highly controlled environment not open for public consumption. Thus, it sits behind a firewall.
Hybrid Cloud: Most companies use a combination of private computing resources and public services, called the hybrid cloud environment. 
Multi-Cloud: Some companies, in addition, also use a variety of public cloud services to support the different developer and business units – called a multi-cloud environment

5. What are the main constituents that are part of the cloud ecosystem?
The parts of the cloud ecosystem that determine how you view the cloud architecture are:
Cloud consumers
Direct customers
Cloud service providers
