Understanding Performance of PayPal as a Service (PPAAS)

image_pdfimage_print

In a previous post – Agile Performance Testing – Proactively Managing Performance – I discussed some of the challenges faced in managing a successful performance engineering practices in an Agile development model.  Let’s continue this with a real world example, highlighting how AppDynamics simplifies the collection and comparison of Key Performance Indicators (KPIs) to give visibility into an Agile development team’s integration with PayPal as a Service (PPaaS).

Our dev team is tasked with building a new shopping cart and checkout capability for an online merchant. They have designed a simple Java Enterprise architecture with a web front-end, built on Apache TomEE, a set of mid-tier services, on JBoss AS 7, and have chosen to integrate with PayPal as the backend payment processor. With PayPal’s Mobile, REST and Classic SDKs, integrating secure payments into their app is a snap and our team knows this is a good choice.

However, the merchant has tight Service Level Agreements (SLAs) and it’s critical the team proactively analyze, and resolve, performance issues in pre-production as part of their Agile process. In order to prepare for meeting these SLAs, they plan to use AppDynamics as part of development and performance testing for end-to-end visibility, and to collect and compare KPIs across sprints.

The dev team is agile and are continuously integrating into their QA test and performance environment. During one of the first sprints they created a basic checkout flow, which is shown below:

For this sprint they stubbed several of the service calls to PayPal, but coded the first step in authenticating — getting an OAuth Access Token, used to validate payments.

Enabling AppDynamics on their application was trivial, and the dev team got immediate end-to-end visibility into their application flow, performance timings across all tiers, as well as the initial call to PayPal. Based on some initial performance testing everything looks great!

NOTE: in our example AppDynamics is configured to identify backend HTTP Requests (REST Service Invocations) using the first 3 segments of the target URL. This is an easy change and the updated configuration is automatically pushed to the AppDynamics agent without any need to change config files, or restart the application.

In a later sprint, our dev team finished integrating the full payments process flow. They’re using PayPal’s SDK and while it’s a seamless integration, they’re unclear exactly what calls to PayPal are happening under the covers.

Because AppDynamics automatically discovers, maps, and scores all incoming transactions end-to-end, our dev team was able to get immediate and full visibility into two new REST invocations, authorization and payment.

The dynamic discovery of AppDynamics is extremely important in an Agile, continuous integration, or continuous release models where code is constantly changing. Having to manually configure what methods to monitor is a burden that degrades a team’s efficiency.

Needing to understand performance across the two sprints, the team leverages AppDynamics’ Compare Releases functionality to quickly understand the difference between performance runs across the sprints.

AppDynamics flow map visualize the difference in transaction flow between the sprints, highlighting the additional REST calls required to fully process the payment. Also, the KPI comparison gives the dev team an easy way to quickly measure the differences in performance.

Performance has changed, as expected, when implementing the full payment processing flow. During a performance test AppDynamics automatically identifies and takes diagnostics on the abnormal transactions.

Untitled6

Transaction Snapshots capture source line of code call graphs, end-to-end across the Web and Service tiers. Drilling down across the call graphs, the dev team clearly identifies the payment service as the long running call.

AppDynamics provides full context on the REST invocation, and highlights the SDK was configured to talk to PayPal’s sandbox environment, explaining the occasional high-response times.

To recap, our Agile dev team leveraged AppDynamics to get deep end-to-end visibility across their pre-production application environment. AppDynamics release comparison provided the means to understand differences in the checkout flows across sprints, and the dynamic discovery, application mapping, and automatic detection allowed the team to quickly understand and quantify their interactions with PayPal. When transactions deviated away from normal, AppDynamics automatically identified and captured the slowness to provide end-to-end source line of code root-cause analysis.

In high-production environments where release cycles are measured in hours or minutes — not days or weeks — there's little room for mistakes and no room for confusion. Everyone has to understand what's happening, in real time, and have the means to do whatever is necessary to keep applications up and running optimally.

DevOps is a high-stakes world, but done well, it delivers the agility and performance to significantly impact business competitiveness.

Through WebRTC, audio and video communications are being embedded more easily than ever into applications, helping carriers, enterprises and independent software vendors deliver greater functionality to their end users. With today’s business world increasingly focused on outcomes, users’ growing calls for ease of use, and businesses craving smarter, tighter integration, what’s the next step in delivering a richer, more immersive experience? That richer, more fully integrated experience comes about through a Communications Platform as a Service which allows for messaging, screen sharing, video...
Consumer IoT applications provide data about the user that just doesn’t exist in traditional PC or mobile web applications. This rich data, or “context,” enables the highly personalized consumer experiences that characterize many consumer IoT apps. This same data is also providing brands with unprecedented insight into how their connected products are being used, while, at the same time, powering highly targeted engagement and marketing opportunities. In his session at @ThingsExpo, Nathan Treloar, President and COO of Bebaio, will explore examples of brands transforming their businesses by t...
Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.

The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.
