A small survey of hosting (~ 100) on the service VDS

Hello. It happened to me to conduct a small survey of hosting services for the VDS service, I want to share. If someone in response wants to share the experience of hosting mailing services, I will be glad. If someone has experience developing mailing lists or a ready-made software product, then let me know (in person).

Prehistory

Once again I didn’t agree with the management and once again looked for work. When you are looking for a job, you have to meet with different people, who for some reason are not looking for a ready-made software product, but a programmer who will write it.



Someone needs an online store, someone CRM. There is nothing unique in the customer's requirements; they are usually looking for a programmer, because they are not familiar with the software market, but there are exceptions. For example, a customer needs a mailing list service, a database of 500,000 addresses is collected, but there is no possibility to make a distribution. MailChimp services are fabulously expensive, other services take the base, take the money, but do not send the newsletter. Therefore, the customer is forced to do development.



When the task was voiced to me, without thinking, I said what I would do in a week. All that is needed is a web application for managing the subscription base, so that people can sign / unsubscribe and the mechanism for sending emails through the mailing list - it seems nothing complicated.

')

But later it turned out that there is no mail server, and that for mailing lists it is necessary to configure it in a special way, otherwise the letters will be sent to junk and the server itself will be permanently banned. Configuring a mail server means having your own dedicated server — that is, regular hosting for a web site does not fit, you need at least Virtual Dedicated Server.



I am not familiar with the VDS market, so I had to get acquainted.

Introduction to VDS Providers

Google was asked a question “vps hosting russia”, in response, two reviews of hosting sites and links to the hosting companies themselves were received, I walked through the first 10 pages of search results (November 12, 2016). Why russia? Because in development it is important to talk with technical support in the same language, in operation, when all the rakes are known and instructions for working out “accidents” are written, then it is possible to communicate in a “foreign” English language.



On the websites of providers where in the contacts was the address of the mail, I wrote a letter, where there was only a feedback form - I left a request. There were also such hosting sites where the telephone was the only method of communication, I never had the desire to call.

Text of the letter:

Hello.



I am looking for a hosting site for hosting mailing services (you need to host an email server).



Now the service is in development and it is necessary to send no more than 50,000 letters per day, it is planned that in working mode there will be sending from 500,000 to 1,000,000 letters per day.



Which of your tariffs for VDS hosting can you recommend for the service development period?



Please let us know what features your hosting has by the following parameters:



- editing DNS zone (creating records with types: NS A CNAME MX TXT SPF)

- posting PTR records

- Internet speed

- unlimited traffic

- maximum SSD capacity

- placement only on SSD carriers

- the amount of RAM

- maximum number of processor cores

- the ability to backup

- VDS backup copy limit

- backup storage period

- the number of backups and the frequency of their creation

- execution time of the application for backup deployment

- response time for the application to deploy the backup

- the ability to upload a backup VDS

- nomenclature of virtualization systems used

- nomenclature of operating systems

- time to complete the application for a "clean" OS installation (with the loss of all "user" data)

- reaction time for an application for a “clean” OS installation

- pre-installed software nomenclature

- the presence of the control panel parameters VDS, OS and other software

- the ability to monitor and view the usage history of hosting resources (load of cores, RAM and permanent memory, Internet channel speed, traffic volume per day or month)

- hosting restrictions on using TCP / UDP ports

- hosting restrictions on the maximum instantaneous channel bandwidth (per second)

- hosting restrictions on the maximum daily traffic volume

- DDoS protection

- availability of telephone hotline (in Russian)

- hotline access time



Did your hosting site and technical support have experience in hosting and maintaining such mail services?

The letter was sent to 79 addresses, in addition, at least 20 applications were left. The questions in my opinion are key when choosing a provider, but as it turned out, I was mistaken in my assessments, because in essence I received the answer only from 18 providers, the rest, to put it mildly, sent me by forest.



Total 18 / (79 + 20) * 100% = 18%, only 18% of providers have a desire to talk on the merits.

PTR records are recorded manually; if necessary, we can change them for your IP addresses. The speed of the channel to which the server is connected is 1 Gbit / s, the limit for virtual server is 100 Mbps. Unlimited traffic.



For virtual servers at the moment we do not provide backup. But we can provide backup space for your server if necessary. With the number of places, frequency, etc. need to negotiate separately.



If necessary, there is also the possibility of protection from DDoS attacks from the upstream provider. We also provide server administration services and work with it of varying complexity, but we need to know more specific details of your project.

DNS zone editing (creating records with types: NS A CNAME MX TXT SPF).

It depends on how you set up the server, but this possibility is not excluded.

Our clients are independently engaged in the placement and administration of their servers. We provide free support to VDS users in the framework of answers to general and financial questions, and consultations on the work of the NetAngels control panel.

If there are technical problems, we can offer server technical support services for a fee. The cost of paid services listed on the page and will depend on the total duration of the work, as well as on the time of day and the day of the week at the time of their implementation.

The VDS service does not provide DNS support, in this case you can use the following solutions:

1) support your domain as part of the DNS-master service

2) install and configure a primary DNS server on your server and maintain a domain on secondary DNS servers as part of the Secondary service

3) use third-party DNS servers.

On the virtual server, we do not host mail servers.

OK, please answer the remaining questions:

- maximum SSD capacity

- placement only on SSD carriers

- the amount of RAM

- maximum number of processor cores

This you choose, we will supply everything that is required.

On the page ** choose the appropriate processor, there will also be a resource calculator: memory, disks.

If something is necessary unique, then inform, we will count.

- the ability to backup

- VDS backup copy limit

- backup storage period

- the number of backups and the frequency of their creation

If we are talking about a physical server.

Then we provide a place via FTP, backup what you need yourself.

Keep as much as you want, depends on how much space you buy and how much backup.

- execution time of the application for backup deployment

- response time for the application to deploy the backup

Depends on complexity, usually during the day.

Recovery from backup is paid (if tech support is not connected), 400rub, within an hour (depending on the size of the disk), we can switch on from backup faster and transfer to the working storage later (but backup is SATA disks).

Uploading a backup copy of 400rub, once done for free.

Combine the answers to these questions in one. The reaction time is instantaneous, after pressing the “buy” button in the user's personal account, since the server is created automatically. The creation time of the VDS will depend on the installed OS. For Linux, this is 5-15 minutes, for Windows a little more - 20-30 minutes.
