AbstractThis paper pertains to an analytical approach towards establishing standards for network performance on the cloud. Cloud being the most promising domain, is yet hindered by the lack of standardization. To resolve this issue we propose a methodology suitable for all essential protocols in contrasting network architectures. In addition to this, security breaches also sever the threat on cloud data and it's privacy. To bridge the two imperative aspects of a cloud service, we intend to deploy a Deep learning classification model on Google colab, acting as an interface between the cloud database and client-server. Essential parameters including throughput(X), average delay(), loss function(l) and accuracy. We extend to present our results as the optimized cloud standards.
Cloud computing is the new phase of technology which has revolutionized the way computing is done rudimentarily. Cloud Computing is the on demand delivery of computational resources via the Internet. The computational resources generally provided are data storage and computation capability. Cloud Computing in general solves many of the obstacles to efficient computing such as requirement of a powerful hardware, computation of excess cycles, redundant cycles of software updates or incompetent handling of high loads. This new technology has also created certain new challenges and obstacles in terms of network infrastructure and security parameters which pose to be extremely hazardous in terms of security and privacy. The lack of standardization in the industry of cloud computing has also led to additional problems which has been the motivation for the work on this project.

Cloud architecture refers to the various constituents in terms of databases, capabilities and applications which leverage the power of cloud resources to direct towards a specific complication which defines the relation between the components. Based on the occurring relationship between the components, the types of architecture are Software as Service (SaaS), Infrastructure as Service (IaaS), Platform as a Service (Paas). The cloud deployment model designates how the cloud services are made available to the
users. The deployment models corresponding to cloud computation services are Public Cloud, Private Cloud, Hybrid Cloud, Community Cloud. In the rush to improve the cloud services and their interfaces, a great deal of companies often ends up ignoring the most critical aspect of their service, that being the network infrastructure. For many companies it is imperative that they massively improve their network infrastructure as it is evident that with the expansion of cloud services the data traffic is only bound to increase in the networks which will make data access difficult be it from a remote location in the world or an institutions headquarters. Some of the principal aspects of a network are Bandwidth, Throughput, Latency. The mere action of improvement of infrastructure does not necessarily yield better network performance. Certain strategies could be implemented beforehand to further improve the network performance. Some of the optimization techniques include Caching, Compression, Traffic Management, Deduplication. There are various security mechanisms in the cloud which can be implemented to ensure the data privacy and security. Encryption is the most common method used for security mechanisms as various algorithms can be executed with them.
When encryption is applied on the plaintext data, the data is paired with a string of characters which is termed as an encryption key, a secret key that is established and shared
among the relevant parties involved. Then the encryption key is used to decrypt the ciphertext back into its plaintext which was its original format. If any external third-party attempts to eavesdrop, it would be unsuccessful as it would not have the encryption key. The two most preferred forms of encryption are Symmetric Encryption, Asymmetric Encryption. Based on this the various algorithms which are implemented for cloud security are RSA Algorithm, DES Algorithm,Â·AES Algorithm, Blowfish Algorithm
The process implemented is as, the pilot study was conducted to ensure the smooth on going of the project. The project was started with a prior study for project specification , Cost Estimation, Resources implemented and the timeline. The project specifications includes the analysis of the various protocols in two different topologies that have to be carried out in terms of the Throughput, Average Delay, Accuracy, Loss function, Complexity, and Security. We are really proud to mention that our project is really economic as we are using the easily available resources in our department labs. For the cloud simulations we are using Tensorflow library in Google colab which is a free of cost available open source platform for cloud processing purposes. For the security parameters also, we are using the Jupyter notebooks on Google colab. So our estimated cost is really low and it only includes the paperwork and other hardware.
Experimental Data Obtained
Primary data is the data being obtained from the first hand experiments on the cloud environment. For network performance we have taken the throughput, Average Delay and the comparative graphs. To obtain the performance on cloud we have checked the loss function and accuracy for the Deep Learning Model deployed on the cloud platform of Google colab. The inference obtained from the primary data and the conclusion drawn is secondary data.
Interpreted Comparative Study
For the project our secondary data is the comparative data we obtained by comparing the various results and analysing them. The result will be a comparative study of the parameters. Data analysis is an imperative part of our study which includes the measurement of data, recording of data into concise tabular formats.
Then for the purpose of comparative analysis, the obtained results are plotted into graphical representations. For the execution of all these tasks, we are implementing Google Sheets as the primary data analysis tool. The application was used to graphically
represent the obtained results for a clearer understanding and better inference to derive a conclusion for the results. We have analysed the network performance and the security parameters separately. The network parameters were analysed on an available LAN server-client system. The security parameters were analysed by implementing various algorithms on cloud compilers and measuring the executing times with their complexit. As a common platform to bridge them both, we have used Google colab as a cloud platform for implementing a real time deep learning classification model with Tensorflow library and obtaining the loss function, accuracy and training time per sample.
The study had 2 different parts involving the network infrastructure and security parameters. Heres a brief description of the system design of the network infrastructure.

Fig.3.2. The Real Time Hardware System
The above image is a pictographic representation of the LAN Kit. The analysis of the network infrastructure was done using a LAN client-server kit. The client PC and the server/sender PC were connected to the LAN Kit with connecting wires.
These kits provide a menu driven interface and a C library which can give an access to the programming interface to the NIU. This kit has 6 nodes per NEU, meaning 3 parties can be connected but we have connected for concise and clear results. The parameters recorded in this setup are offered load, throughput and average delay.
Next, we evaluate the cloud system design which involves the use of Tensorflow library and the cloud platform, Google colab.
Fig.3.3. The Real Time Cloud Implementation Model
To begin, we first import the Tensorflow library in the Google Colab and create an object for the Tensorflow library. Then using Keras we download a training dataset where we import the matplot and other relevant libraries. After importing the Keras, we label the objects in the data set succeeding which the pre-processing of training images takes place. Then we apply convolutional flatten and max pooling layers to analyse the data and to generate an inference. Then we obtain the models accuracy, loss and time per sample to build a
classification model and obtain the relevant results. Here we implement the model with 10 – 1000 Epochs . Epoch in this algorithm is defined as the number of training instances per training attempt for a model with the same training data set. The concept of Epoch is applied here to demonstrate the optimization technique of Caching which refers to caching of frequently used images in a user's local disk. To analyse the security parameters, we proposed four different security encryption methods for the security of data.
The data from the system was recorded in a concise manner with a tabular representation as follows.

CSMA/CA: – It has a stiff slope & saturates after threshold . As Data rate increases – Stiffness
ncreases in CSMA/CA.
CSMA/CD: – Slope increases gradually & later decreases after threshold . As Data rate increases
– Slope gradually tends towards stiffness.
Throughput v/s IPD
CSMA/CA: As IPD increases Throughput decreases but changes are slower. As Data rate increases , no significant change in the graph.
CSMA/CD: As IPD increases Throughput decreases but changes are faster in CSMA/CA compared to CSMA/CD. As Data rate increases, no significant change in the graph
IPD v/s Offered Load
CSMA/CA: – As IPD increases offered load decreases & vice versa. As Data rate increases no significant change in the graph
CSMA/CD: -As IPD increases offered load decreases & vice versa. Data rate increases rate of change of slope also increases
For the security when given the same binary input, most of the algorithms took over 4 seconds to execute. AES Algorithm took only 1.5 seconds to encrypt the data which was the fastest. AES Algorithm also requires the lowest memory to be run, making it the most viable option
The analytical study of the security parameters and network performance established standards pertaining to cloud. CSMA/CA was found to be the most suitable and optimized protocol for networking in cloud. In terms of security, AES algorithm performed in the most efficient manner in terms of execution time.
