There is given Cloud Computing interview questions and answers that has been asked in many companies. Let's see the list of top Cloud Computing interview questions.
Cloud computing is an internet based new age computer technology. It is the next stage technology that uses the clouds to provide the services whenever and wherever the user need it.It provides a method to access several servers world wide.
The main benefits of cloud computing are:
A cloud is a combination of networks ,hardware, services, storage, and interfaces that helps in delivering computing as a service. It has three users :
There are different data types in cloud computing like emails, contracts, images , blogs etc. As we know that data is increasing day by day so it is needed to new data types to store these new data. For an example, if you want to store video then you need a new data type.
Following are the different layers that are used by cloud architecture:
The following platforms are used for large scale cloud computing:
There are 3 layers in the hierarchy of cloud computing.
Infrastructure as a service (IaaS):It provides cloud infrastructure in terms of hardware as like memory, processor, speed etc.
Platform as a service (PaaS):It provides cloud application platform for the developer.
Software as a service (SaaS)::It provides the cloud applications to users directly without installing anything on the system. These applications remains on cloud.
Software As a Service (SaaS) is an important layer of cloud computing. It provides cloud applications like Google is doing. It facilitate users to save their document on the cloud and create as well.
It is also a layer in cloud architecture. This model is built on the infrastructure model and provide resources like computers, storage and network. It is responsible to provide complete virtualization of the infrastructure layer, make it look like a single server and invisible for outside world.
Cloud computing provides a on-demand access to the virtualized IT resources. It can be used by the subscriber. It uses shared pool to provide configurable resources. Shared pool contains networks, servers, storage, applications and services.
Apache Hadoop and MapReduce are the platforms use for large scale cloud computing.
These are the different deployment model in cloud computing:
Private cloud
Public cloud
Hybrid cloud
Community cloud
Private clouds are used to keep the strategic operations and other reasons secure. It is a complete platform which is fully functional and can be owned, operated and restricted to only an organization or an industry. Now a day, most of the organizations have moved to private clouds due to security concerns. Virtual private cloud is being used that operate by a hosting company.
The public clouds are open to the people for use and deployment. For example: Google and Amazon etc. The public clouds focus on a few layers like cloud application, infrastructure providing and providing platform markets.
Hybrid clouds are the combination of public clouds and private clouds. It is preferred over both the clouds because it applies most robust approach to implement cloud architecture. It includes the functionalities and features of both the worlds. It allows organizations to create their own cloud and allow them to give the control over to someone else as well.
Mobile computing and cloud computing are slightly same in concept. Mobile computing uses the concept of cloud computing . Cloud computing provides users the data which they required while in mobile computing, applications run on the remote server and gives user the access for storage and manage.
Scalability is a characteristic of cloud computing which is used to handle the increasing workload by increasing in proportion amount of resource capacity. By the use of scalability, the architecture provides on demand resources if the requirement is being raised by the traffic. Whereas, Elasticity is a characteristic which provides the concept of commissioning and decommissioning of large amount of resource capacity dynamically. It is measured by the speed by which the resources are coming on demand and the usage of the resources.
Cloud computing authorizes the application service, so it is used in identity management.
It provides permissions to the users so that they can control the access of another user who is entering into the cloud environment.
Utility computing is a plug-in managed by an organization which decides what type of services has to be deployed from the cloud. It facilitates users to pay only for what they use.
It is an acronym stands for Elastic Utility Computing Architecture For Linking Your Program To Useful Systems. It is an open source software infrastructure in cloud computing and used to implement clusters in cloud computing platform. It creates public, private and hybrid cloud. It facilitate a user to create his own data center into a private cloud and use its functionalities to many other organizations.
System integrator provides a strategy of a complicated process used to design a cloud platform. It creates more accurate hybrid and private cloud network because integrator have all the knowledge about the data center creation.
MongoDB, CouchDB, LucidDB are the example of open source cloud computing platform database.
Google bigtable
Amazon simpleDB
Cloud based SQL
The cost of the traditional datacenter is higher than cloud because in traditional databases, there is overheating problems and some software and hardware issue.
Simple Multi-tenancy:In this mode, Every user has independent resources and are uniquely different from other users. This is an efficient mode.
Fine grain multi-tenancy:: In this mode, the resources can be shared by many users but the functionality remains the same.
API's (Application Programming Interfaces) is used in cloud platform because:
It provide an alternative way that you don't need to write the fully fledged program.
It makes communication between one or more applications.
It creates applications and link the cloud services with other systems.
Following are the main advantages of cloud services:
CaaS is a terminology used in telecom industry as Communication As a Service. CaaS offers the enterprise user features such as desktop call control, unified messaging and desktop faxing.
VPN stands for Virtual Private Network. VPN is a private cloud that manage the security of the data during the communication in the cloud environment. With VPN, you can make a public network as private network.
There are three basic clouds in cloud computing:
There are three core services provided by Window azure operating system:
The main usage of virtualization platform in implementing cloud is:
Following are the open source cloud computing platform databases:
Following are the mostly used large cloud providers and databases:
This is the most obvious question accurued in mind that if the cloud data is secure; To ensure that, check that there is no data leak with the encryption key implemented with the data you sending while the data moves from point A to point B in cloud.
