RCFS is a distributed file system which has been developed for the purpose of this course and which uses a relational database for its metadata management and a NoSQL database for its data management. In this lab we have implemented Round Robin and Least Connection load balancing algorithms with Nginx in order to balance the requests between our RCFS nodes in the most efficient way possible. We have compared the results of these two algorithms and found that the Round Robin algorithm performs better than Least Connection algorithm in our environment since it assigns the requests to the nodes in equal proportions regardless of their current load and thus prevents overloading any particular node. section*{textbf{Introduction}} As stated before, RCFS is a distributed file system which uses a relational database for its metadata management and a NoSQL database for its data management. In order to scale RCFS horizontally we have developed an Nginx based proxy server which acts as a load balancer and distributes the requests between different RCFS nodes. In this lab we have implemented Round Robin and Least Connection load balancing algorithms with Nginx in order to balance the requests between our RCFS nodes in the most efficient way possible. After we have implemented these two algorithms we have compared their performances by running tests on our RCFS cluster and analyzed the results of these tests. The rest of this report is organized as follows: begin{itemize} item Section~ref{sec:impl} gives an overview of the implementation details of Round Robin and Least Connection algorithms in Nginx. Section~ref{sec:results} describes our experimental setup and presents the results of our tests comparing these two algorithms. end{itemize} section*{textbf{Implementation}} label{sec:impl} In this section we will explain how Round Robin and Least Connection algorithms are implemented with Nginx in our RCFS cluster. As mentioned before we have developed an Nginx based proxy server which acts as a load balancer and distributes the requests between different RCFS nodes. The configuration file for this proxy server is given below: lstinputlisting[language=C++, firstline=7]{../nginx/nginx.conf} As seen from the configuration file above we have two upstreams which correspond to two different load balancing algorithms that we have implemented in this lab; round-robin and least-connection. The first upstream is called "round-robin" which is basically the default setting for upstream servers in Nginx so we do not need to specify anything regarding the load balancing algorithm when defining this upstream; Nginx will use Round Robin algorithm automatically when assigning requests to servers defined under this upstream group. On the other hand when defining "least-connection" upstream group we need to specify "least_conn" parameter so that Nginx knows that it should use Least Connection algorithm when assigning requests to servers defined under this upstream group: begin{lstlisting}[language=C++, frame=single] upstream least-connection { least_conn; server node1; server node2; server node3; server node4; server node5; } end{lstlisting} Now that we have defined both upstream groups it is time to define locations where these upstream groups will be used: begin{lstlisting}[language=C++, frame=single] location / { proxy_pass http://round-robin; # Uncomment following line if you want to use least-connection algorithm # proxy_pass http://least-connection; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # This parameter will tell Nginx whether or not it should buffer responses from backend servers # before sending them to clients proxy_buffering off; # This parameter will tell Nginx to forward all headers from client requests except Host header # which will be replaced with $host value specified above proxy_set_header Host $host; } end{lstlisting} As seen from above code block location "/" means that any request made to proxy server will be handled by either "round-robin" or "least-connection" upstream group depending on whether or not second line is commented out: So if second line is uncommented then all incoming requests will be forwarded to "least-connection" upstream group whereas if second line is commented out then all incoming requests will be forwarded to "round-robin" upstream group since first line is not commented out: section*{textbf{Results}} label{sec:results} In this section we will explain how we have tested Round Robin and Least Connection algorithms by running experiments on our RCFS cluster and what results did we obtain from these tests. First of all let us describe our experimental setup: We have three machines running Ubuntu Server with IP addresses listed below: begin{itemize} item Proxy Server : IP Address = 192.168.56.101 item Node1 : IP Address = 192.168.56.102 item Node2 : IP Address = 192.168.56.103 We have configured each machine as follows: begin{itemize} Proxy Server : Apache Web Server has been installed on Proxy Server but disabled since it is not needed for this lab work but only Nginx has been installed on Proxy Server. On top of that MySQL and Cassandra databases are also installed on Proxy Server so that it can manage metadata and data respectively while acting as one of our RCFS nodes. Node1 : Apache Web Server has been installed on Node1 but disabled since it is not needed for this lab work but only MySQL database has been installed on Node1 so that it can manage metadata while acting as one of our RCFS nodes. Node2 : Apache Web Server has been installed on Node2 but disabled since it is not needed for this lab work but only Cassandra database has been installed on Node2 so that it can manage data while acting as one of our RCFS nodes. } end{itemize} As mentioned above we have used Apache Benchmark tool (ab) in order to test performance of Round Robin and Least Connection algorithms by making HTTP GET requests towards different RCFS nodes via our proxy server: Since ab tool does not support HTTPS protocol (as seen from its documentation) we had to run ab tool against HTTP endpoints instead of HTTPS endpoints because although SSL termination has been implemented in our proxy server it only terminates SSL connections coming from clients towards proxy server but does not re-establish SSL connections towards backend servers; therefore in order to test HTTPS endpoints with ab tool we had to use HTTP endpoints instead. Now let us see how these tests were performed: First of all we ran ab tool against HTTP endpoint "/create/10/10000000" which creates ten files with size equal to ten million bytes each by making ten HTTP POST requests towards our proxy server via port number "8080" using Round Robin algorithm (since second line under location "/" block in nginx.conf file was commented out): Following command was executed on Proxy Server: {scriptsize ~~~~ ~~~~ ~~~~ ~~~~ ~~~~ ~~~~ ab -n100000 -c100 -k -e create_rr_10_10000000.csv -g create_rr_10_10000000.json http://localhost:8080/create/10/10000000 ~~~~ ~~~~ ~~~~ ~~~~ ~~~~ ~~~~ } The output produced by ab tool was saved into two files; csv file named create_rr_10_10000000.csv and json file named create_rr_10_10000000.json : Following are some lines taken from create_rr_10_10000000.csv: {scriptsize ~~~~ ~~~~ Percentage served within certain times 50% 77ms 66% 77ms 75% 77ms 80% 78ms 90% 79ms
