Telecom Reaps Benefits from Service Virtualization

Service Virtualization brings speed benefit and lower costs to TTNET applications testing

Welcome to the latest edition of the HP Discover Performance Podcast Series. Our next discussion examines how TTNET, the largest internet service provider in Turkey, with six million subscribers, significantly improved applications deployment while cutting costs and time to delivery.

We'll hear how TTNET deployed advanced Service Virtualization (SV) solutions to automate end-to-end test cases, gaining a path to integrated Unified Functional Testing (UFT).

To learn how, we're joined by Hasan Yükselten, Test and Release Manager at TTNET, which is a subsidiary of Türk Telekom, based in Istanbul. The interview is conducted by Dana Gardner, Principal Analyst at Interarbor Solutions. [Disclosure: HP is a sponsor of this and other BriefingsDirect podcasts.]

Here are some excerpts:

Gardner: What was the situation there before you became more automated, before you started to use more software tools?

Yükselten: We're the leading ISP in Turkey. We deploy more than 200 applications per year, and we have to provide better and faster services to our customers every week, every month. Before HP SV, we had to use the other test infrastructures in our test cases.

 

Yükselten

We mostly had problems on issues such as the accessibility, authorization, downtime, and private data for reaching the other third-party’s infrastructures. So, we needed virtualization on our test systems, and we needed automation for getting fast deployment to make the release time shorter. And of course, we needed to reduce our cost. So, we decided to solve the problems by implementing SV.

Gardner: How did you move from where you were to where you wanted to be?

Yükselten: Before SV, we couldn’t do automation, since the other parties are in discrete locations and it was difficult to reach the other systems. We could automate functional test cases, but for end-to-end test cases, it was impossible to do automation.

First, we implemented SV for virtualizing the other systems, and we put SV between our infrastructure and the third-party infrastructure. We learned the requests and responses and then could use SV instead of the other party infrastructure.

Automation tools

After this, we could also use automation tools. We managed to use automation tools via integrating Unified Functional Testing (UFT) and SV tools, and now we can run automation test cases and end-to-end test cases on SV.

We started to use SV in our test systems first. When we saw the success, we decided to implement SV for the development systems also.

Gardner: Give me a sense of the type of applications we’re talking about.

Yükselten: We are mostly working on customer relationship management (CRM) applications. We deploy more than 200 applications per year and we have more than six million customers. We have to offer new campaigns and make some transformations for new customers, etc.

We have to save all the informations, and while saving the information, we also interact the other systems, for example the National Identity System, through telecom systems, public switched telephone network (PSTN) systems.

We have to ask informations and we need make some requests to the other systems. So, we need to use all the other systems in our CRM systems. And we also have internet protocol television (IPTV) products, value added services products, and the company products. But basically, we’re using CRM systems for our development and for our systems.

Gardner: So clearly, these are mission-critical applications essential to your business, your growth, and your ability to compete in your market.

Yükselten: If there is a mistake, a big error in our system, the next day, we cannot sell anything. We cannot do anything all over Turkey.

Gardner: Let's talk a bit about the adoption of SV. What you actually have in place so far?

Yükselten: Actually, it was very easy to adopt these products into our system, because including proof of concept (PoC), we could use this tool in six weeks. We spent first two weeks for the PoC and after four weeks, we managed to use the tool.

Easy to implement

For the first six weeks, we could use SV for 45 percent of end-to-end test cases. In 10 weeks, 95 percent of our test cases could be run on SV. It was very easy to implement. After that, we also implemented two other SVs in our other systems. So, we're now using three SV systems. One is for development, one is just for the campaigns, and one is for the E2E tests.

HP Software helped us so much, especially R&D. HP Turkey helped us, because we were also using application lifecycle management (ALM) tools before SV. We were using QTP LoadRunners, Quality Center, etc., so we had a good relation with HP Software.

Since SV is a new tool, we needed a lot of customization for our needs, and HP Software was always with us. They were very quick to answer our questions and to return for our development needs. We managed to use the tool in six weeks, because of HP’s Rapid Solutions.

Gardner: My understanding is that you have something on the order of 150 services. You use 50 regularly, but you're able to then spin up and use others on a more ad-hoc basis. Why is it important for you to have that kind of flexibility and agility?

We virtualized all the web services, but we use just what we need in our test cases.

Yükselten: We virtualized more than 150 services, but we use 48 of them actively. We use these portions of the service because we virtualized our third-party infrastructures for our needs. For example, we virtualized all the other CRM systems, but we don’t need all of them. In gateway remote, you can simulate all the other web services totally. So, we virtualized all the web services, but we use just what we need in our test cases.

In three months we got the investment back actually, maybe shorter than three months. It could have been two and half months. For example, for the campaign test cases, we gained 100 percent of efficiency. Before HP, we could run just seven campaigns in a month, but after HP, we managed to run 14 campaigns in a month.

We gained 100 percent efficiency and three man-months in this way, because three test engineers were working on campaigns like this. For another example, last month we got the metrics and we saw that we had a total blockage for seven days, so that was 21 working days for March. We saved 33 percent of our manpower with SV and there are 20 test engineers working on it. We gained 140 man-months last month.

For our basic test scenarios, we could run all test cases in 112 hours. After SV, we managed to run it in 54 hours. So we gained 100 percent efficiency in that area and also managed to do automation for the campaign test cases. We managed to automate 52 percent of our campaign test cases, and this meant a very big efficiency for us. Totally, we saved more than $50,000 per month.

Broader applications

Gardner: Do you expect now to be able to take this to a larger set of applications across Türk Telekom?

Yükselten: Yes. Türk Telekom licenses these tools and started to use these tools in their test service to get this efficiency for those systems. We have a branch company called AVEA, and they also want to use this tool. After our getting this efficiency, many companies want to use this virtualization. Eight companies visited us in Turkey to get our experiences on this tool. Many companies want this and want to use this tool in their test systems.

Gardner: Do you have any advice for other organizations like those you've been describing, now that you have done this? Any recommendations on what you would advise others that might help them improve on how they do it?

Yükselten: Companies must know their needs first. For example, in our company, we have three blockage systems for third parties and the other systems don't change everyday. So it was easy to implement SV in our systems and virtualize the other systems. We don’t need to do virtualization day by day, because the other systems don't change every day.

Once a month, we consult and change our systems, update our web services on SV, and this is enough for us. But if the other party's systems changes day by day or frequently, it may be difficult to do virtualization every day.

Companies should think automation besides virtualization. This is also a very efficient aspect, so this must be also considered while making virtualization.

This is an important point. Companies should think automation besides virtualization. This is also a very efficient aspect, so this must be also considered while making virtualization.

We started to use UFT with integrating SV. As I told you, we managed to automate 52 percent of our campaign test cases so far. So we would like to go on and try to automate more test cases, our end-to-end test cases, the basic scenarios, and other systems.

Our first goal is doing more automation with SV and UFT and the other is using SV in development sites. We plan to find early defects in development sites and getting more quality products into the test.

Rapid deployment

Of course, in this way, we get rapid deployment and we make shorter release times because the product will have more quality. Using performance test and SV also helps us on performance. We use HP LoadRunner for our performance test cases. We have three goals now, and the last one is using SV with integrating LoadRunner.

Gardner: Well, it's really impressive. It sounds as if you put in place the technologies that will allow you to move very rapidly, to even a larger payback. So congratulations on that.

At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices. Sessions focused not just on the cultural shift needed to grow at scale with a DevOps approach, but also made sure to include the network ”plumbing” needed to ensure success as applications decompose into the microservice architectures enabling rapid growth and support for the Internet of (Every)Things.
Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?

JavaScript is primarily a client-based dynamic scripting language most commonly used within web browsers as client-side scripts to interact with the user, browser, and communicate asynchronously to servers. If you have been part of any web-based development, odds are you have worked with JavaScript in one form or another. In this article, I'll focus on the aspects of JavaScript that are relevant within the Node.js environment.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...

Software is eating the world. The more it eats, the bigger the mountain of data and wealth of valuable insights to digest and act on. Forward facing customer-centric IT organizations, leaders and professionals are looking to answer questions like how much revenue was lost today from platinum users not converting because they experienced poor mobile app performance. This requires a single, real-time pane of glass for end-to-end analytics covering business, customer, and IT operational data.
Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.
"ProfitBricks was founded in 2010 and we are the painless cloud - and we are also the Infrastructure as a Service 2.0 company," noted Achim Weiss, Chief Executive Officer and Co-Founder of ProfitBricks, in this SYS-CON.tv interview at 16th Cloud Expo, held June 9-11, 2015, at the Javits Center in New York City.
You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
