Application programming interface is nothing but a set of protocol and standards which ultimately defines the communication among software application with the help of internet. A malicious insider can be also considered to be a threat to network in cloud domain (Hao & Shihong, 2015). In many cases, it is seen that cloud computing provides various kinds of services by proper sharing of infrastructure, platform and lastly infrastructure.
Relevant technologies and Application
Relevant technologies in cloud computing are Amazon web service, Google app engine and lastly Microsoft office 365.
Amazon Web Service: AWS is nothing but a collection of remote computing services which can easily create a cloud platform. Various customers which get benefited from AWS are Netflix, SmugMug and lastly wetransfer (Rao & Selvamani, 2015). AWS provides reliable, secure and inexpensive infrastructure for storing and retrieving any amount of data. Amazon provides a platform on which data of client can be organized and stored for achieving objectives. AWS provides a well-known database for developers and customer for huge storage of data. Users round the globe can easily run their data on fully managed relation and NoSQL database or can easily create a database in Amazon EBS and EC2. Amazon SQS is known to be distributed the message for queuing of service (Zhang, C., & Green, R. (2015). This service is mainly used for short messaging when they are transferred between computers and application layers which are considered to be highly scalable. It generally provides various kinds of an authentication procedure for secure handling of various kind of data. In this message are generally stored on various kinds of servers for ensuring of availability.
Google app engine: Google App Engine (GAE) in cloud computing is a well-known platform which can be used for managing and developing web application in various google infrastructure (Inukollu, Arsi & Ravuri, 2014). Development and maintaining of this application are considered to be easy and this application can be considered as a traffic and growth in storage is needed. Infrastructure facilities like server and its maintenance are not required for the development in GAE and so it is deployed. GAE mainly consist of large number of phases like runtime environment, Datastore, service. In traditional design there is the usage of a relational database for persistent usage of data, on the contrary, it makes use of different approach name Bigtable. Various kinds of the option provided by GAE for data storage are NoSQL, cloud SQL and lastly cloud storage.
Challenges and problem associated with Cloud Computing
There is a large number of challenges and problems which are associated with cloud computing like security, costing model and many other.
