Cloud platform Websa It includes several products at once: cloud servers, CDN, cloud storage based on Swift OpenStack and free Anycast DNS, however, this article will focus on cloud servers.
Registration, trial period and payment
Registration on the platform quite simple – you need to specify an email account and come up with or generate a password for the account. The ability to register through Google is also available. Subsequently, you can activate 2FA in your account.
After registration, the user can freely move around the panel and get acquainted with its functionality. To order any of the services you will need to enter credit card information to verify your account.
Further, the user has two options – activate the test period or immediately pay for full access. To do this, you need to replenish the account in the amount of $ 10. When choosing a test mode, new users receive $ 50 on their balance. They must be used within 20 days. After the end of the test period, the balance of the unused bonus will be debited from the account.
After activating the test mode, the Interkassa service is added to the credit card recharge option, through which you can pay almost anything, including cryptocurrencies. However, the commission in this case will be quite serious, so we recommend that you still use the card.
Cloud Server Cost
The cost of servers varies from 3 to 500 dollars a month. At the same time, hourly billing is calculated at the rate of 672 hours per month (billing is disabled after 28 days when the server is constantly used). The volume of traffic starts at 5 TB for cheap tariffs and ends at 100 TB for the most expensive.
In general, tariffs are cheaper than those of well-known providers – such as DigitalOcean, OVH, Scaleway.
CPU power is not guaranteed. Although in the future a line of tariffs with guaranteed capacities is planned.
In addition to the public cloud, it is possible to order a dedicated infrastructure, for this you need to contact the sales department. Using a combination of private and public clouds allows you to create a hybrid cloud infrastructure.
Locations and iron
For location of servers, two locations are offered – this is Ashburn (USA) and Amsterdam (Netherlands). Both data centers correspond to Tier IV level.
Cloud servers are based on KVM virtualization technology. As for hardware, all tariffs have NVMe SSDs. They are much faster than regular SSDs, not to mention the “oldies” of the HDD. The presence of RAID10 minimizes the risk of data loss.
The servers run on Intel processors with a base frequency of at least 2.1 GHz. If we talk about the supplied OS, then a variety of Linux options are presented, namely the current versions of CentOS, Ubuntu, Debian, Fedora and openSUSE.
Additional sections and internal networks
Those wishing to get cheaper disk space have a similar opportunity. Users have the option to purchase additional volumes (volumes) that can be connected to servers. They work in hot-swap mode, that is, partitions can be connected, disconnected and expanded without stopping the server. Even Amazon cannot boast of such options.
In addition to this, users are offered the choice between double or triple data replication options. The cost for additional memory starts at $ 0.02 per gigabyte per month, and the maximum volume size is 10 TB.
Cloud infrastructure can be integrated into internal networks, thereby saving on traffic and receiving additional protection from external influences. The main feature of networks is that they are free between the data centers, that is, you do not pay for internal traffic even when it goes through the Atlantic.
Automatic and manual backup
When creating a server, you can choose to automatically backup for 10% of its cost. The system stores six weekly backups, which are created automatically. In addition, at any time you can make an instant copy of the server (snapshot) in manual mode. This service has a different tariffing and will cost $ 0.03 for storing one gigabyte of data per month. Both from backups and snapshots, you can make a new server at any time or roll back to the previous version. Creating a backup or snapshot does not require stopping the server.
API, mass server creation and upgrades
The cloud platform offers a complete API for working with all products. So automation lovers will not remain indifferent, especially considering that the platform allows you to create up to 10 servers at once through both the API and the web interface.
At any time, the tariff can be replaced with the option with the best features, however, this will require a server reboot.
Administration and Support
Administration is not included in the price of tariff plans, as the service is designed for experienced users. But if you want to get the help of technical experts, then it will cost $ 50 per hour. This, however, does not apply to standard non-technical issues. The support service responds quickly, and you can contact it through a ticket from the user's account.
Additional IPv4 addresses can be ordered through the support team, however this option is not available in trial mode.
Cloud Server Testing
For the test, we took one virtual machine from each tariff line in the Ashburn location:
- Start XS (1 vCPU, 1 GB RAM, 10 GB NVMe SSD, 5 TB of traffic) for $ 3 per month
- Smart XS (4 vCPU, 8 GB RAM, 80 GB NVMe SSD, 20 TB of traffic) for $ 30 per month
- Pro M (16 vCPU, 64 GB RAM, 640 GB NVMe SSD, 50 TB of traffic) for $ 160 per month
Channels of connection
To test the network capabilities, we decided to use the server of one of the Russian providers. First, we ping our VPS with a hundred small (64 bytes) and a hundred large (1 kilobyte) packets: packets do not beat (0% loss), and the average response time is 128 milliseconds. For such a long network route, the result is not bad – Google DNS servers, for example, respond from a test VPS with a much shorter response time – less than a millisecond.
Next, we will test the download of hundred-megabyte files of the tested virtual machine using the wget utility:
$ wget -O / dev / null – http://ftp.corbina.ru/pub/100Mb
$ wget -O / dev / null – http://cachefly.cachefly.net/100mb.test
$ wget -O / dev / null – http://speedtest.london.linode.com/100MB-london.bin
The test results can be seen in the table:
|speed, MB / sec||18.1||128||31.4|
Finally, we’ll measure the speed using the iperf client-server utility. On the external Russian VPS, start the server:
$ iperf -s -p 9999
Then, on the Advanced Hosting machine, the command is executed:
$ iperf -c server_ip -p 9999 -t 60
Testing took 60 seconds, the average data transfer rate was 168 Mbps. For the sake of interest, we repeated the test using virtual machines located not in Russia but in Europe and America as a remote server: the speed was much higher – 249 Mbit / s and 658 Mbit / s, respectively.
The performance of cloud servers was measured using the GeekBench 5 utility. It does about two dozen synthetic tests, checking the operation of various compression algorithms, JPEG processing, HTML parsing, SQLite and so on. Synthetic tests do not give an idea of the ability of the machine to cope with the needs of a real project, but, without knowing the specifics, load testing is impossible. Much also depends on the workload of the physical host on which the virtual machines are running.
Disk subsystem performance
To test the execution of read / write operations in random order, we used the fio utility.
Here are the test results.
|Start xs||Smart xs||Pro m|
|Read speed, IOPS||65500||52100||41200|
|Read speed, mb / s||537||427||337|
|Latency (average reading), ms||0.67752||0.85450||1.07854|
|Write speed, IOPS||28,200||22,400||17700|
|Write Speed, MB / s||231||184||145|
|Latency (average value during recording), ms||0.69085||0.86278||1.10252|
As you can see from the test results, the speed of the drives is at a high level, because even on the cheapest tariff plans customers can use fast NVMe SSDs. A slight decrease in write / read performance is quite natural with an increase in the volume of the drive at more expensive rates.
Advanced Hosting's cloud servers offer a serious set of features. Servers can be combined in networks, connecting volumes that are powerful in capabilities. They work on top-end hardware, can be controlled by API and are located in reliable Tier IV data centers. Other advantages: RAID10, the ability to manually and automatically create a backup without stopping the server, additional account protection using two-factor authentication.
The product is perfect for companies that have their own administrators and devops, or just experienced users who understand what to do with a clean Linux image, but are not ready to overpay for the cloud infrastructure.
