SelectelTechDay: as it was
On April ? the third SelectelTechDay conference took place, bringing together about 200 representatives of organizations from various fields of activity. The atmosphere of friendly communication, interesting reports and interactive demonstration of the possibilities of the new Selectel VMware Cloud service are just some of the events in which the guests of the event took part.
The recording of the event is available on our Youtube channel .
Presentations by speakers are available for viewing by reference .
Let's talk about everything in order, welcome to the cat.
In the engineering room, from where the round-the-clock control over the operation of all data center systems is conducted, the head of the engineering department, Tatyana Svirko, told what parameters are monitored by the on-duty specialists.
The next stopping points were:
server rooms with the placed equipment of our customers;
Stand with the equipment Selectotel, providing the work of our services;
places of installation of power units, cabinets of power supplies and a hall with batteries of uninterrupted power supply;
server rooms with a protected perimeter.
During the excursions, visitors were told in detail about how the data centers are arranged, what measures are taken in case of emergency situations and how to preserve the equipment and data intact.
For many who have been with us for the first time, it has become a completely new knowledge.
"We work closely with VMware products and I was interested in visiting a modern data center with a VMware server zone. I expect interesting reports on the implementation of the VMware cloud in your data center »
(Fast Lane, manager)
"It was interesting to visit the data center. In our company, its a small data center, it was curious to find out how it is organized for large uncles. I understood the jambs that we have, and that's not so bad. Looked at the server, estimated the scale. Of course, there is no shock, everything is as it should be. It was amusing to see racks with "towers" and hanging wires to compare with your neat racks. I wish you: develop further. You are on the border of technology - the future is on, if you keep such a pace, you will always have something to show. Just keep developing. "
(Technical Director of Teleklic)
New service Selectel VMware Cloud
A significant event happened on the day of the conference - a new Selectel VMware Cloud service was launched, a cloud solution that allows creating a private and hybrid cloud based on VMware software and Intel hardware platform. The service came out of testing and became available to customers. Now you can order a virtual data center with payment for actual consumption of resources.
The new service is aimed at customers who already use VMware virtualization in their IT infrastructure, and is positioned to use on 4 possible scenarios:
expanding your own data center to the cloud;
making working applications in the cloud;
Cloud as a backup data center;
cloud for application development and testing.
All these scenarios are paid for using the system. Pay-as-you-go with hourly billing. The main focus was on enabling customers to build their own hybrid cloud based on a new service. This allows you to habitually use the existing infrastructure, if necessary, using the resources of Selectel for rapid scaling or redundancy.
Cloud Selectel VMware Cloud deployed on the basis of data centers Dubrovka-3 (main data center) and Flower-2 (backup data center). In the solution there are so-called arbitration servers installed in the data center Flower-1 (the main arbiter) and Berzarina-1 (reserve referee). Thus, arbitration servers constantly monitor the availability of the main and backup data centers, initiating the process of restarting virtual machines in the event that any of them is completely inaccessible.
Alexander Krenev, manager of the development of the direction of network virtualization in Russia and the CIS, from VMware in his report noted that at the moment it is the hyperconvertive architecture implemented in Selectel VMware Cloud that is the most popular on the market, allowing to manage everything from one point and immediately increase capacity when necessary.
He also talked about how you can migrate between the clouds and about the capabilities of the NSX software network platform and the vSAN technology that allows you to create "stretched" clusters for data storage.
To ensure high performance of the infrastructure, Intel solutions optimized for use in systems with hyperconvergent architecture were used as a hardware platform:
are used as processors. Intel Xeon Gold 6140 ;
As drives, a combination of NVME disks is used. Intel P4600 (for the cache) and Intel P3520 (for the data).
The network part is implemented hardware based on Brocade equipment, and as a software solution for virtualizing networks within virtual data centers, a powerful tool is used. VMware NSX . Its main advantage in the flexibility of configuration and the convenience of managing complex network configurations.
Reports of partners
The SelectelTechDay conference brought together speakers from representatives of the leaders of the IT industry: VMware, Intel, Microsoft, Veeam . Here are the reports most memorable for the audience:
Maxim Didik, Microsoft Partner Representative, spoke about the benefits of using cloud technologies and the concept of "digital transformation" in the foreseeable future.
Dmitry Ilyin, the Director for work with suppliers of the MONT group of companies, presented a presentation to the guests, in which he told about possible options and schemes for licensing Microsoft products in the cloud infrastructure.
Sergey Kunko, a system engineer at Veeam, provided information about new features of software products that provide backup and recovery of data from various applications and services deployed in the cloud environment.
After lunch break, the guests of the conference waited for the announced demonstration. The fact is that beautiful and loud words very often disagree with the real state of affairs. That is why the man-made "catastrophe" was planned, which will be discussed further.
A live demonstration of the reliability of Selectel VMware Cloud
In order to guarantee the operation of the systems, even if there are problems in the data center, it is necessary to provide fault tolerance of clouds for virtual machines.
Alexander Tugov, director of service development, and Roman Dashevsky, project manager for VMware, Selectel, conducted a demonstration of the operation of our infrastructure, in the situation of abnormal power outages on the main site, thereby emulating the total inaccessibility of the data center.
Preparation of the demo stand
As our "domestic work" our specialists carried out the following actions:
In two data centers - Dubrovka-3 and Flower-2 A fault-tolerant VMware resource pool based on technology was created. Stretched vSAN .
In this pool resources are created from control panel a virtual data center with the appropriate characteristics.
We deployed the test site to WordPress in a virtual machine.
Prepared a demonstration dashboard with monitoring using Grafana .
Demonstration in real time
An interactive demonstration was planned in the afternoon, and, by the way, the conference participants were waiting for it with impatience.
One of the pages of the test site was edited, selecting the message "Good luck!" From the audience. All the guests of the conference could also monitor the availability of the site directly from their laptops and mobile devices.
On the screen were displayed:
Dashboard with metrics of cluster availability;
The control panel my.selectel.ru ;
A test site deployed on a virtual machine;
The terminal that verifies the site's pings.
The power of the leading engineer Artem Anisimov was turned off the power of all servers in the half of the cluster located in the data center Dubrovka-3 .
On the dashboard with monitoring, the disabling of servers located in Dubrovka-3 was displayed. In the terminal, echo requests are no longer loaded, and the test site has stopped booting from client devices.
The virtual machine restarted in the second half of the cluster, and the test site was re-accessed in a minute with all the current data, which did not fall back into the past and was not lost.
After turning on the power at the servers at Dubrovka-? the hosts of the virtual machines went up within 5 minutes and became fully accessible, as guests could observe on the dashboard.
Reviews of our guests
During the event, we tried not only to provide interesting information, but also to learn the opinions of listeners. Let's give them a call:
"Everything went fine. I really liked the tour of the data center: interesting and informative. An interesting experiment with power outages, it's really cool that the company is ready to demonstrate in the combat production the performance of its own products. And what is very important in such events is a large number of useful contacts. We already exchanged business cards with some representatives of the companies. Perhaps we will work in the future. "
(CEO of Vee Security OÜ)
"An interesting trend is the trend of migration to the clouds. Came to be aware of new products, aware of what is happening. We are your partners - we rent racks and virtual servers for resale. I heard what I wanted, it's always pleasant for me to be in the Selectel - everything is organized according to the highest standard, questions are asked by the participants, you can learn a lot for yourself. I do not regret that I came here (laughs). I'm on SelectelTechDay for the second time, and once again I'm convinced that Selectel is a serious firm, professionals. I appreciated this for a long time: Selectel is a reliable solution for those who are going to deploy[здесь]business "
(deputy head of the development department of the company "Nauka-Svyaz")
Perhaps the most pleasant part of the conference was its final, when the prize draw was held. The winners, whose names were selected in a random order, received gifts from Selectel and partner companies.
I would like to note that the holding of SelectelTechDay in the current format would be impossible without the support of our information partners:
RBC St. Petersburg (General Information Partner)
