As a result of a literature search it was found that a three tier architecture would be the most suitable for this project.

Three-Tier Architecture
Three-Tier software architecture (Figure 1.1) started in the 1990’s to overcome the limitations of two-tier architecture (Figure 1.2), such as that it is not scalable as each client requires its own connection to the database. In a three tier architecture the middle tier lies between the User interface (Web Application) and the Data Management (Server) and provides process management where business logic and rules are executed. This makes the application highly scalable. Where two tier architecture (Client/Server) can support a max of 100 connections, which would be good for a Medium sized organisation, the three tier architecture allows for a couple of hundred connections. Figure 1.1 …show more content…
This tier is responsible for performing complex business logic.

Data Storage:

This tier provides database management functionality and is dedicated to data and file services. As such this tier contains the file system and the database. Further, because the database will contain only information regarding files, the actual file system containing the media content resides in the Data Storage tier too.

The diagram below (Figure 1) show’s a “light weight” architecture that uses REST.
One of the benefits of this architecture is that the data services are completely decoupled from the applications that consume them. This means, in real live there could be one team working on the web client and another team working on the Spring Boot Micro Service.
Another advantage is that there could be as many Web Clients or Mobile clients as necessary, which makes the access very versatile.

In old school apps the view and server side logic were often interleaved e.g. JSP/Servlets. Using the architecture shown here you expose a set of services that anyone can consume.

There are important roles in our proposed model that control execution of all process in the system. Every role affects the efficiency of the proposed model to provide best services for cloud users. These roles are listed as follows: 1- PKG gives data owner user public key (user ID) for every user in the system. 2- The Data Owner stores encrypted files on the cloud server with attributes. 3- When a user requests access, he would obtain the file`s secret key from the Data Owner. 4- Cloud Server gives…

Two advances in technology began to change Information technology. The first was the development of powerful microprocessors. The current generation of computers have the computing power of the mainframes deployed 30 or 40 years ago, but for 1/1000th of the price or less ( Steen, & Tanenbaum, 2016). The second development was the invention of high-speed computer networks. Local-area networks or LANs allow thousands of machines within a building or campus to be connected in such a…

passwords on our server by simply logging into it. b. Emphasize on why we need cloud database. Currently our application makes use of a temporary dedicated server (i.e. limited accessibility). It is a server system that refers to a physical storage unit, which can be located in any part of the world. Such servers have mechanical parts associated with them, and data from various web applications are stored there based on the cluster allocated to that application, usually entire server gets allocated…

3.5 Data Integrity by Trusted TPA Using MHT:- In HDFS, the data is stored in multiple racks at a data center in a cloud environment. Each rack is stored at the main assignment table in rows and columns. The rows consist of multiple blocks, and the columns contain multiple nodes. However, the issue of large datasets arises. The solution to this problem of large datasets is data partition (i.e, breaking larger datasets into blocks). The data items stored in each block are linked by a block pointer…
