Introduction

The main goal of the work here presented in this GitHub repository is to explore new cloud native microservices based application resiliency on the IBM Cloud Private (ICP) platform. The desired outcome for this work would be a list of some recommendations and things to watch out as far as how to build resilient cloud native microservices based applications on the IBM Cloud Private (ICP) platform.

The work methodology we have chosen consists of using a representative application for each of the different scenarios application resiliency on IBM Cloud Private (ICP) extensive field might involve, execute some load test on it while simulating platform failures and observe the resiliency of the application while writing down not only its behaviour but the reasons behind it, what is wrong/failing, what can be enhanced, etc. It is important to note that we consider the middleware the application might use totally resilient and therefore taking it out of the equation by not simulating platform failures for them.

Different application resiliency on IBM Cloud Private scenarios could be any combination of the following application type and IBM Cloud Private (ICP) topology:

Application:
1. Cloud native stateless microservices based application.
2. Cloud native stateful microservices based application.
3. Legacy stateless monolithic application.
4. Legacy stateful monolithic application.
IBM Cloud Private (ICP) topology:
1. Simple ICP cluster on a datacenter.
2. Federated/Stretched ICP cluster.

Does the above make sense?? Frame it otherwise.

In order to get us started, we have picked what we consider as the easiest scenario: a stateless microservices based application on a simple IBM Cloud Private (ICP) cluster.

The stateless microservices based application we are going to use for this first application resiliency on IBM Cloud Private (ICP) effort is called the IBM StockTrader Application.

IBM StockTrader Application

The IBM StockTrader Application main goal is to showcase how IBM middleware can fit into the new hybrid cloud era where most of the uses cases will have a private cloud (on-premise resources) that needs to interact with services/resources on/from a public cloud provider (or more).

As a result, the IBM StockTrader Application is mostly a Java MicroProfile based microservices application which tries to leverage containerised IBM middleware such as IBM MQ, IBM DB2 and IBM ODM running on IBM Cloud Private (ICP) and integrate with IBM Cloud Public services and some third party notification applications like Slack and Twitter.

The overall architecture looks like the following diagram:

Where you can find IBM StockTrader specific microservices in blue and IBM middleware in purple all running on IBM Cloud Private (ICP), IBM Cloud Public services in green and other third party applications in other different colours.

Installation

The actual IBM StockTrader Application GitHub repository where the instructions on how to get it installed (with the middleware, third party applications and other integrations it depends on) is located at https://github.com/jesusmah/stocktrader-app/tree/v2.

Please, follow the instructions on the GitHub repository above to get the IBM StockTrader Application successfully installed and verified.

As you could read in the IBM StockTrader installation instructions, there are two Backend For Frontend (BFF) microservices whereby to interact with the IBM StockTrader Application: Trader and Tradr. Although both integrate with the IBMid service for authentication and authorisation (using the Open ID Connect protocol - OIDC), we have deployed the basicregistry version of the Trader BFF microservice (also recommended in the installation instructions by the way) which allows us a simpler access to the IBM StockTrader Application to run our tests. Therefore, bear in mind for the following sections that we are accessing our IBM StockTrader Application instance through the Trader BFF microservice by using a simple user/password (stock/trader) credentials.

Application flow

There are mainly 4 actions you can execute against the IBM StockTrader Application once you are logged in:

Create a portfolio, where
1. A GET addPortfolio request is sent to the trader microservice (BFF) from the browser by the user which returns a form to be filled with the new portfolio name (1).
2. trader microservice (BFF) sends a POST addPortfolio request to the portfolio microservice with the new portfolio's data from the previous form to get the portfolio created (2).
3. portfolio microservice interacts with the DB2 database through a JDBC Datasource to create the appropriate records and structure in the DB for the new portfolio (3).
4. Once the portfolio microservice returns a successful message for the POST addPortfolio request to the trader microservice BFF, this requests a GET summary to the portfolio microservice to display a summary of the application to the end user (2).
Delete a portfolio.
1. A POST summary request is sent to the trader microservice (BFF) from the browser by the user with the action delete and owner portfolio name as parameters (1).
2. trader microservice (BFF) creates and sends another POST request to the portfolio microservice(2).
3. portfolio microservice interacts with the DB2 database through a JDBC Datasource to delete the appropriate records and structure in the DB for the portfolio indicated (3).
4. Once the portfolio microservice returns a successful message for the POST request to the trader microservice BFF, this requests a GET summary to the portfolio microservice to display a summary of the application to the end user (2).
Add stock to an existing portfolio.
1. A POST summary request is sent to the trader microservice (BFF) from the browser by the user with the action update and owner portfolio name as parameters (1).
2. trader microservice (BFF) redirects the request to itself by sending a GET addStock request in order to present the user with a form to input what shares (company) and how many shares to update a portfolio with.
3. This GET addStock request makes the trader microservice (BFF) to send a GET request to the portfolio microservice in order to retrieve the portfolio's next commission to be shown in the form presented to the user. This form will be used by the user to input what shares (company) and how many they want to update the portfolio with (2).
4. The trader microservice (BFF) returns a new page to the user with the form to add stock to be filled up.
5. The user inputs what shares and how many they want a particular portfolio to be updated with and that sends a POST addStock with the portfolio and what shares and how many shares to update it with from the trader BFF microservice to the portfolio microservice(2).
6. Now the portfolio microservice will interact with IBM DB2 through a JDBC Datasource, IBM MQ through a JMS resource and IBM ODM and the stock quote microservice through rest calls as follows:
  1. Process the commission for the portfolio update. That is, add the total of commissions for this portfolio (3).
  2. Increment the amount of shares of the share type (company) the user decided to update the portfolio with (3).
  3. Recalculate the total balance of the portfolio with the new amount of shares already added. To do this, the portfolio microservice will send a GET to the stock quote microservice to retrieve the current value for that type of share (4) . The stock quote microservice will:
    1. Check if the Redis cache attached to the stock quote microservice contains an acceptable up-to-date value for the type of share requested (5).
    2. If it does, it will return such value. Otherwise, the stock quote microservice will call the external IEX service through the API Connect service set up in IBM Cloud Public (6).
  4. Now that a new total balance for the portfolio to be updated has been calculated, the portfolio microservice will process the loyalty level for this portfolio. This will make a POST request to the IBM ODM with the total balance for the portfolio. IBM ODM will return the associated loyalty level for such balance (7).
  5. If the loyalty level has changed, the portfolio microservice will send a message to the IBM MQ with the portfolio name along with the old and new loyalty levels (8).
7. The messaging microservice will be listening to an specific queue on the IBM MQ for messages being dropped by the portfolio microservice (9).
8. If a message (with a portfolio name and old and new loyalty levels) has been dropped into the IBM MQ, the messaging microservice will send a POST request to the notification-service which will end up reaching the Notification (Twitter) or Notification (Slack) microservice depending on which notification route we had selected at installation time (10).
9. Based on that notification route option chosen at the installation time, either the Notification (Twitter) microservice will post a tweet to the configured Twitter account or the Notification (Slack) microservice will post a message to the configured Slack channel with the portfolio name and the old and new loyalties (11).
Retrieve a portfolio.
1. A POST summary request is sent to the trader microservice (BFF) from the browser by the user with the action retrieve and owner portfolio name as parameters (1).
2. trader microservice (BFF) sends a GET viewPortfolio request to the portfolio microservice with the portfolio name (2).
3. portfolio microservice interacts with the DB2 database through a JDBC Datasource to retrieve the appropriate records and data from the DB for the portfolio indicated (3).
4. portfolio microservice returns all the data for the portfolio specified by the user to the trader microservice (BFF)and this presents it to the end user on the browser (2).

Loyalty Levels

The loyalty levels for the IBM StockTrader Application are set as follows:

Loyalty Level	Stock
BASIC	0 - 10.000
BRONZE	10.001 - 50.000
SILVER	50.001 - 100.000
GOLD	100.001 - 1.000.000
PLATINUM	> 1.000.001

Test

In this section we provide plain shell scripts to

Perform basic load test on the IBM StockTrader Application through its basicregistry Trader BFF microservice by simulating common user interaction with the application. This load test executes end-to-end scenarios trying to exercise all IBM StockTrader Application components as much as possible.

Simulate IBM Cloud Private (ICP) platform Kubernetes pod failures that compromises the IBM StockTrader Application resiliency. chaos.sh

Again, the IBM StockTrader's backend for frontend (BFF) microservice used to carry out the test is the Trader microservice. As already mentioned in this readme, the Trader microservice is served in two versions as far as the authentication and authorisation of the requests is concerned. One uses plain user and password (basicregistry) and the other integrates with the IBMid service as the Identity Provider (IP) for the Open ID Connect (OIDC) mechanism (latest).

Load Test

The IBM StockTrader load test scripts will interact with the IBM StockTrader Application through REST calls against the Trader backend for frontend (BFF) microservice. The load test scripts workflow looks like:

Remove the output from previous executions (output directory).
Log into the StockTrader Application (only on the _basic_registry shell scripts).
Delete existing portfolios from previous executions.
For each iteration, it will for each portfolio
1. Create the portfolio if it is iteration number 1.
2. Add the amount of shares specified for each of the symbols (IBM, APPLE and GOOGLE) multiplied by a factor.
3. Create a summary for the iteration into the output directory (summary_iteration_#.html or summary_thread_#_iteration_#.html).
Create a final summary (summary_final.html) and export the database (portfolio_final.txt and stock_final.txt) reports into the output directory so that we can make sure the application has function as expected.

There is a second version of the script above where the main body (point 4) has been threaded in order to get a better request per second throughput. Those scripts are preceded with threaded_ on their file names.

Finally, both the sequential and threaded versions have got their login section tailored to the two already well mentioned Trader microservice authentication and authorisation mechanisms basicregistry and latest.

As a result, we count with 4 load test scripts which we explain in further detail below.

IMPORTANT: given the loyalty levels for the IBM StockTrader Application detailed above in this this readme, use a Multiplication factor for shares of 2 in the following load test scripts if you want to exponentially increment the amount of shares to add to the portfolios per iteration and, as a result, reach higher levels of loyalty and better stress the messaging and notification pieces of the IBM StockTrader Application architecture.

IMPORTANT: The load test scripts below are developed to meet the IBM StockTrader Application installation explained in its GitHub repository. Therefore, make sure you have the correct configuration of your hosts file beforehand.

trader_main_looper_basic_registry.sh

The trader_main_looper_basic_registry.sh will execute the workflow described in the Load Test section above in a sequential manner with the login section automated using stock and trader as user and password when the Trader microservice version deployed is basicregistry.

The trader_main_looper_basic_registry.sh script expects the following parameters:

$1: Number of iterations.
$2: Number of portfolios.
$3: Number of shares to add of each symbol per portfolio and iteration.
$4: Multiplication factor for shares.

Example: sh trader_main_looper_basic_registry.sh 3 6 1 1

trader_main_looper_oidc.sh

The trader_main_looper_oidc.sh script will do exactly the same as the previous basicregistry version but will not log into the application automatically. The reason for this is that we encountered some problems automating such task which did not make sense to invest more time investigating.

As a result, the logging into the IBM StockTrader Application latest version has to be done manually and the appropriate associated cookies exported in order to get this load test OIDC version script executed. To export the appropriate cookies associated with the manual logging into the IBM StockTrader Application, we have used Firefox to log into the IBM StockTrader Application and the cookies.txt Firefox add-on for exporting the cookies.

The trader_main_looper_oidc.sh script expects the following parameters:

$1: Number of iterations.
$2: Number of portfolios.
$3: Number of shares to add of each symbol per portfolio and iteration.
$4: Multiplication factor for shares.
$5: IBM StockTrader authorisation and authorisation cookies file.

Example: sh trader_main_looper_oidc.sh 3 6 1 1 cookies.txt

trader_threaded_main_looper_basic_registry.sh and trader_threaded_main_looper_oidc.sh

The trader_threaded_main_looper_basic_registry.sh and trader_threaded_main_looper_oidc.sh scripts will work exactly the same as their non-threaded versions explained above but will execute the main stock adding workflow piece in parallel for a better request per second throughput.

That is, from these scripts we will execute the trader_user_loop.sh script in parallel as many times as threads has the main load test scripts been specified with:

for thread in $(seq $NUM_THREADS)
do
  echo "[`date '+%H:%M:%S'`] [MAIN] - Executing trader_user_loop.sh script for [THREAD_${thread}]"
  sh trader_user_loop.sh ${INGRESS} ${thread} ${NUM_ITERATIONS} ${NUM_USERS} ${NUMBER_OF_SHARES} ${COOKIE_FILE} ${DIRECTORY} &
done

where trader_user_loop.sh, will, in turn and in parallel, execute the adding stock code from the non-threaded script versions.

The trader_threaded_main_looper_basic_registry.sh and trader_threaded_main_looper_oidc.sh scripts expects the following parameters:

$1: Number of threads
$2: Number of iterations
$3: Number of users
$4: Number of shares to add of each symbol per portfolio and iteration
$5: Multiplication factor for shares.
$6: IBM StockTrader authorisation and authorisation cookies file (oidc version only).

Example: sh trader_threaded_main_looper_basic_registry.sh 2 3 6 1 1

Example: sh trader_threaded_main_looper_oidc.sh 2 3 6 1 1 cookies.txt (oidc version)

Execution

Here we are going to demo the execution of the non-threaded basicregistry version of the load test scripts and what the output of it would be (the threaded version would create more users which would just generate higher requests per second):

$ sh main_looper_basic_registry.sh 172.16.40.176 32370 4 2 20 1

As we can read above, the load test script has created two users (portfolios) to which has added 20 shares per symbol (IBM, GOOGLE, ORACLE) each iteration (4 iterations) making IBM StockTrader to look like this

and our twitter account to look like this after having those two portfolios progressed few loyalty levels up:

As explained in the Load Test section, the load test scripts also produce some more detailed test results into the output directory:

$ ls output
portfolio_final.txt
stock_final.txt
summary_final.html
summary_iteration_1.html
summary_iteration_2.html
summary_iteration_3.html
summary_iteration_4.html

where the summary html files would be a graphical snapshot of who the IBM StockTrader Application looks like after each iteration and at the end of the load test script execution and portfolio.txt and stock_final.txt an IBM StockTrader Application database dump at the end of the load test script execution:

$ cat portfolio_final.txt

Load Test Throughput

The load test throughput may vary depending on your ICP cluster configuration, overhead, network connection, etc. However, here is the load test throughput at the time this was carried out.

The number of requests the load test scripts make to the IBM StockTrader Application Trader Backend For Frontend (BFF) microservice is calculated considering main loops only and leaving out preparation or summary requests. The equations look like this:

trader_main_looper_basic_registry.sh = #Users + ( #Iteration * #Users * #Symbols(=3) ) + #Iterations
trader_threaded_main_looper_basic_registry.sh = #Threads * ( #Users + ( #Iterations * #Users * #Symbols(=3) ) + #Iterations )

The following table describes the load test scripts maximum throughput when the load test scripts were executed against the IBM StockTrader Application with the Twitter notification route enabled on a cluster with IBM Cloud Private 2.1.0.2:

Replica 3

	#Threads	#Iterations	#Users	#Requests	Avg. Duration (sec)	Throughput (req/sec)
trader_threaded_main_looper_basic_registry.sh	3	10	4	402	313	1.28

The following table describes the load test scripts maximum throughput when the load test scripts were executed against the IBM StockTrader Application with the Slack notification route enabled on a cluster with IBM Cloud Private 2.1.0.3:

Replica 3

	#Threads	#Iterations	#Users	#Requests	Avg. Duration (sec)	Throughput (req/sec)
trader_threaded_main_looper_basic_registry.sh	4	10	4	536	225	2.38

where all IBM StockTrader Application microservices are scaled up to 3 replicas (except from the Trader backend for frontend microservice which can not scale due to some WebSphere Liberty SSO credentials sharing limitation).

Monkey Chaos

This section covers the implementation of a Kubernetes pod failure shell script. The script is actually called chaos.sh and it is a tailored piece of the work presented in this GitHub repository by Eduardo Patrocinio to suit our needs.

Given a namespace (default namespace is default), the IBM StockTrader Application Helm release name and a delay (default 10 seconds), the chaos.sh script will then randomly choose a Running pod within that namespace which belongs to the specified IBM StockTrader Application Helm release and terminate it:

while true; do
  POD=`kubectl \
    --namespace "${NAMESPACE}" \
    -o 'jsonpath={.items[*].metadata.name}' \
    get pods | \
      tr " " "\n" | \
      grep ${UNIQUE_ID} | \
      grep Running | \
      grep -v trad | \
      gshuf | \
      head -n 1`
  echo Deleting Pod ${POD}...
  kubectl --namespace "${NAMESPACE}" delete pod ${POD}
  sleep "${DELAY}"
done

this way we simulate failures on the IBM Cloud Private (ICP) platform that will allow us to study the IBM StockTrader Application resiliency as the cloud native stateless microservices based reference application for the IBM Cloud Private (ICP) resiliency at the application level initial scenario.

Example:

$ sh chaos.sh 10 stocktrader test
[2018-07-03 16:14:15]: Begin of script

Delay: 10
Namespace: stocktrader
Unique ID (Helm release): test

Deleting Pod test-notification-twitter-6dd5f9d7dc-bsfs7...
pod "test-notification-twitter-6dd5f9d7dc-bsfs7" deleted

Deleting Pod test-portfolio-75b4dbd485-k6rq4...
pod "test-portfolio-75b4dbd485-k6rq4" deleted

Deleting Pod test-notification-twitter-6dd5f9d7dc-5rmh4...
pod "test-notification-twitter-6dd5f9d7dc-5rmh4" deleted
^C

As you can see, the chaos.sh script will run until a kill signal is sent to it (ctrl+c).

Test Execution

As already said in this readme, in order to test what we consider the easiest and therefore first step on testing cloud native microservices based applications on the IBM Cloud Private (ICP) platform (that is stateless microservices based applications), we are going to test the IBM StockTrader Application resiliency.

For doing so, we have deployed the IBM StockTrader Application and developed load test scripts for it and a Kubernetes pod failure shell script for the IBM Cloud Private (ICP) platform.

Then, we have scaled our stateless microservices to 3 replicas (except from the backend for frontend Trader microservice(1)) so that we create high availability, increase our application resiliency and minimise the probability that Kubernetes pod failures break our application. There is no point in testing with only one replica as any pod failure will bring our application down.

(1) The reason the backend for frontend (BFF) Trader microservice has not been scaled is due to a WebSphere Liberty SSO limitation which does not allow to share the SSO credentials/cookies amongst several WebSphere Liberty instances. Hence, requests will get redirected several times to the login mechanism. Since the Trader microservice latest version is not able to scale and therefore we are going to have only 1 replica of our backend for frontend (BFF), we have decided to run our tests with the basicregistry version instead as the load test scripts for such version automates the login into the IBM StockTrader Application.

This is how our testing environment looks like in terms of pods:

$ kubectl get pods

that is,

1 replica of our middleware pieces: IBM DB2, IBM MQ, IBM ODM and Redis.
1 replica of our backend for frontend: trader (tradr is not used in this case even though it gets installed with the IBM StockTrader Application Helm chart).
3 replicas of the core IBM StockTrader Application microservices: Portfolio, Stock-quote, Messaging and Notification-Twitter.

Now, the only thing that remains is to execute the load test scripts and the Kubernetes pod failure script at the same time over the IBM StockTrader Application installation you can see above which we have on our IBM Cloud Private (ICP) instance hosted on our lab.

The results of these executions can be found in the test execution readme file.

IMPORTANT: Test execution results will contain test executions for both the Twitter and Slack notification route versions of the IBM StockTrader Application. It is important to note the Twitter API testing limitations which does not let you make more than 50 rest calls per 30 minutes.
