ConoHa

ConoHa (Konoha) is a virtual server hosting service operated by Japan's GMO Internet Corporation.

The contents of the official website for service introduction are excerpted.

It offers a dual-core VPS for 900 yen per month and is a beneficiary of unlimited network traffic . In fact, it is said that up to 30 TB is the traffic limit. In other words, unlimited traffic is a promotional message, and in reality, it is okay to interpret it to the extent that no additional fee is charged even if you use a lot. However, the real advantage is not the unlimited known traffic, but the provided CPU (...) In the case of nearby Japan, ping also comes out well in Korea.

For a Japanese server, it comes out around 80ms, so the ping is higher than other Japanese VPS.[1] But in fact, this is about as good as a web server or VPN. Game servers should be considered. Since the parent company is a solid company, there is not much to worry about going bankrupt.

Monthly rates are for data centers set to Japan ( Tokyo ). If you choose to go to Singapore or the US ( San Jose ), the fare will double.

By the way, the CPU specs are very good.

When a user made a Konoha 1GB/2 core (900 yen) option and tested it under the same conditions as the above, the following results were obtained.
The single-threaded performance is faster than that of Link's companies, and the number of CPU cores provided according to the price plan is twice that of other companies.

 sysbench --test=cpu --cpu-max-prime=20000 --num-threads=1 run -> 28.3539s
sysbench --test=cpu --cpu-max-prime=20000 --num-threads=2 run -> 14.6591s

sysbench --test=cpu --cpu-max-prime=20000 --num-threads=2 run -> 14.3971s 

Cards for deferred payment can be registered as long as they are domestically issued credit cards of VISA, MasterCard, and JCB brands that can be used for overseas payments. In the case of a debit card, it can be used to top up the prepaid amount, but when trying to register with a postpaid card, unlike when using a prepaid card, the debit card is not registered with an error saying that the debit card cannot be used, perhaps because the debit card is not treated as a credit card. .

PayPal is also available for domestic and non-Japanese accounts. However, all payment methods will be blocked if you fail to request payment and registration several times, so you must request it from the customer center.

Charges charged for prepaid use are not refundable under any circumstances. We recommend registering and using a credit card.

In the case of a problem with the terms and conditions, a refund is possible if there is a cause attributable to ConoHa, but even in this case, only the phone is exchanged, and in the end, the answer is that no refund is possible. Regarding the refund request, only macro answers are returned through Japanese mail, so you have to connect a landline phone. As of July 18, 2017, there are no staff who can respond in Korean or English.

Even if the server is stopped, the fee continues to be charged, so if the server is not needed, it must be deleted.

All free OSes support 64-bit architecture, and you can also choose 32-bit.
All items below FreeBSD can only be selected in 64-bit. It is frequently updated, so it is recommended that you go and see it yourself.

It is rumored that the company's VPS has good cost-effectiveness, perhaps because of its unlimited traffic, but its DDoS (DoS) response service is known to be bad. This is because if excessive packets flow into the VPS in service, the account is immediately suspended. If this is the case, let's use Vultr instead . There are also more promotions, such as giving double credits here.

Of course, the hosting is not a DDOS defense zone, so stopping the VPS is to take the right measure for other customers.
However, most hosting companies stop it for 24 hours and release it again, but this does not.

One thing to note here is that if you are running a web service with ConoHa VPS, be sure to use the Cloudflare CDN service. Also, if your real IP is exposed to visitors and crackers , be sure to recreate the VPS and change it. Of course, it is essential to display an error page instead of redirecting to the original page when accessing directly by IP.[6] The point to think about is that the operation of the service (product) is turned from such a cheap service, even if it is a personal / company website. In this case, consider AWS or server hosting.

However, simple overuse (such as torrent seeding of tens of gigabytes per day) is released after 24 hours of 512kbps QoS. It is impossible to use it in a state where restrictions such as QoS are applied, but SSH work is possible enough. Connections such as SSH may also be blocked if there are frequent login failures, so set a package such as Fail2Ban in advance.

5 days a week, 10:00 am - 6:00 pm on weekdays, and the customer service center is closed on Saturdays, Sundays, and Japanese holidays.

Please note that neither the customer inquiry page nor the landline phone will respond. It's so obvious, but what can be overlooked is that there is no contact even on public holidays in Japan . For example, if your VPS is down due to a DDoS attack on Saturday morning, no action can be taken until Monday morning. Even if Monday is a public holiday, you can have a blood-drying experience. As you can see by referring to Japanese holiday documents, there are quite a lot of holidays that fall on the nth Monday of n month. If you want to use ConoHa no matter what, it is recommended that you register Japanese public holidays in your calendar.

However, people who can speak Japanese can receive answers through real-time chatting compared to other companies, so there may be a rather advantageous part. In fact, there is no problem in receiving service support even if you use a translator.

In addition, the website and dashboard are also available in Korean, English and Chinese, but if you make a customer inquiry in Korean or English, all languages ​​are answered in Japanese. Even if you make an inquiry on a landline phone and ask in English, the agent will answer in Japanese.[7] If you sign up with confidence that the service page is in Korean, and there is a problem, there is no answer. For reference, the live chat consultation mentioned above is available from 10:00 am to 6:00 pm on weekdays. Use a translator if necessary.

This is very useful if you are dealing with high-traffic but insignificant material. Because of the above-mentioned DDoS policy, you might want to know what is the benefit, but there are few places that offer 2 E5 physical cores at 900 yen per month . The most typical service that handles high CPU usage and unimportant data is a torrent server or a VPN server.

The torrent server needs to install transmission-daemon, and in the case of Open VPN, Konoha provides an application image. L2TP-IPsec can be installed if you have the ability. A silent installation script is available on GitHub . PPTP is not supported, but it is also not recommended for security reasons in this situation. Apple also recently removed it from supported protocols. However, L2TP is originally a bit complicated to install, and self-sufficiency is an important part.

As a cloud service, the API is at a usable level, and auto scaling can be implemented using this. Because of the high degree of freedom, there are also people who do all sorts of things to the stars, such as dual booting (...). Windows Server does not support it as an image, but it is possible to upload it using the API.

However, the default homepage is much slower than expected, so people in a hurry are recommended to look for other platforms.
Stuttering can be felt even when operating the shell or web service. It is recommended not to use it in mobile services (especially games) because if you feel stuttering on the web, you will feel it 2 to 3 times more on mobile.
