 It's really exciting to see the momentum behind hybrid cloud and how different organizations are using open source technologies to advance this use case. Today, I'm really excited to be joined by Meltem coach of us from Trundale, who is running hybrid cloud in production using open source technologies. Welcome, Meltem. Thank you, Alison. Before we get started on how you're deploying OpenStack and other cloud environments in production, can you provide us a little bit of background around what your organization does? Of course. The organization's name is Trundale, as you said. And Trundale is an e-commerce company. And it's the leader of the marketplace in Turkey. And you can also read here at Trundale.com, actually. Awesome. And so like I said, we're talking about hybrid cloud today. So what clouds are you leveraging at Trundale for your environment? Actually, our hybrid cloud consists of OpenStack, AliCloud, Google Cloud, and Amazon Web Services. Awesome. And so why OpenStack? Why did you choose the open source project as one of your cloud environments? First of all, for freedom, of course, to be open source appeal to us. And then low total cost ownership is another reason. And high massive scalability is a very important reason for that. And the last one is developing on our own technology, of course. So within your hybrid cloud environment, what workloads are you using? Are you choosing to run on your OpenStack environment? First of all, for example, CDN platform run on the Amazon Web Services and BI and big data analysis run on the Google Cloud and some web services on our part, for example, search web services and the discovery, et cetera, run on the AliCloud on our part. OK, so it's definitely a broad hybrid strategy that you have with all of these different clouds, architected together. How many data centers? What is the scale of your hybrid cloud environment? Trandall has four different data centers. Three of them are physical data centers. And one of them is Cloud data center, which is working on the AliCloud. And we are using OpenStack Hyper-V and VMware platforms in our data centers. And in case of high traffic or any problem, we direct to a cloud data center traffic. Awesome. So it's really cool to see how you're using all of the different technologies all together. But zeroing in on OpenStack, how has this technology specifically impacted your organization? Actually, I tried to explain in three different points of view. First of all, deployment. On the deployment part, provision from bare metal to operating system, approximately 100 nodes within one and two hours. And install and configure part, OpenStack on the approximately same 100 nodes in less than one hour. And the second point is resource agility. On this part, time to deploy a 1,000-plus instance average two hours and time to deploy and delete a 1,000-plus instance average 30 minutes. This time is very good on our side, actually. And the last point is scalability. We get the ability to scale, compute, and block storage pool dynamically. Awesome. And you touched on some data points there, but one of the things that I love the most is hearing the scale of your OpenStack deployment. So how big is your OpenStack deployment? Like, how many cores do you have and how many hypervisors? That's definitely where a lot of my passion lies, personally. You're asking for our scale, right? I will explain the total results on three data centers. Compute power over 100,000 cores. And hypervisor over 1,500. And storage area over 5 petabytes. Wow, it's great to see open infrastructure at such scale. We've talked about OpenStack, but are there any other OpenStack open source technologies that you all are deploying over there at Trendyall? Actually, we are using SEF as an open source data storage. And just that for just today, actually. Awesome. Well, it's great to see another open source technology deployed in production. Thank you so much for talking about your hybrid cloud use case today. I've learned a lot. And I think it really shows how this overall momentum is impacting the global industry, and especially there in Turkey. Thank you very much.
