igor-seletsky-cloud-linuxIn this interview B10WH.com presents Igor Seletsky, CEO of CloudLinux. Igor has created a fantastic software automation product, an OS that helps web hosting companies and SaaS provides to optimize resource usage on their servers and to prepare for the Cloud. I can even say that CloudLinux saves smaller hosting providers from fierce competition of larger corporate hosters. I’m not saying superlatives about Igor or about his company’s software. Ask anyone and you’d find out that CloudLinux (CL) is a very popular hosting automation solution. But this is not the reason to feature Igot at B10WH. I wanted to speak to him because I knew he was a great guy and our readers would like meeting him. Here he is!

Tell me how did you come up with the idea to create CloudLinux?

I knew about the problem facing Shared Hosting companies for years. I had developed H-Sphere since 1997, and one of the most critical issues was always single customer affecting all other customers. Yet, we never had a good approach to deal with it. Nor did any of our competitors. So, after few years of not doing software for hosting industry, I took a look at what is going on – and noticed that this problem is still not addressed by anyone. I researched it a bit, and figured out that I have an elegant solution for it. Hence  – CloudLinux.

Did you develop H-Sphere alone? I remember it was quite popular at the time! Can you share with B10WH.com readers how many of you worked on the H-Sphere project?

I started PSOFT (the company behind h-sphere) with a partner back in 1997. In 2005, when it was sold to Comodo, the company had 60+ people, most of them working on H-Sphere, or providing tech support for h-sphere.

OK. I’m curious why didn’t you continue developing web hosting control panels? Was it because you needed to work on something innovative which would resolve any particular technical issue in Shared Hosting industry?

I felt the need to expand the sales/marketing expertise, as well as technical team to compete with cPanel & Parallels. That was the main reason for selling company to Comodo. I thought there is enough control panels on the market, and didn’t want to do something that was already done.

Are you saying you are not tempted to add a hosting control panel as add-on product to CloudLinux in the future?

Not at all. I don’t think there is a need on the market for another control panel. cPanel and Parallels are doing quite a good job, and people who don’t like either of those have a choice of ISPManager, DirectAdmin, InterWorx, HostingController, WebMin, and probably few others that I haven’t heard about.

Which control panels are compatible with CloudLinux?

All that I listed above, and probably some others. Anything that works on CentOS, will work on CloudLinux. We also have quite a few people running CloudLinux with their own, home grown solutions.

Please now explain CloudLinux for dummies! What does it do? What makes it valuable and important for server administrators?

Back in 2010 we asked hosting companies to list top 3 reasons for server downtime. Single customer causing server downtime was the number one reason. Such incidence cause downtime more often then hardware or software failures, security issues, software updates or any other reasons. What CloudLinux does – it prevents ability of customer to cause such downtime. We effectively limit CPU & memory usage of the customer, so if customer starts to overload server – limits will be applied, and customer’s site will be limited (and will be slow or down). Yet, all other sites on the server will not notice any issues.

It is funny. When you say – “We effectively limit CPU & memory usage of the customer, so if customer starts to overload server – limits will be applied, and customer’s site will be limited” – this sounds exactly whata customers do not want. but it is actually more important for site owners, than for web hosts… because CloudLinux keeps the servers up and running and those hosted on them should be happy about it  Isn’t it like that?

Yes, and no. Imagine you have a server with 500 users. One of them causing downtime. 499 of those users really want that solution.

Actually, that extra one customer also want that solution, because when his site brings down the server, the downtime affects him as well. Of course some customers are limited at the moment when they just start slowing down the server, or just hit the limit. Yet, because we provide exact metrics, and show how much CPU was used, and when – most of them are accepting it, and hosts use such data to upsell heavy customers to VPS solutions.

Do you think that hosting providers who use CloudLinux should advertise it to customers and to say things like “Powered by CloudLinux”? Are you working to make CloudLinux popular to all site owners or you need it to be recognizable on an enterprise level only?

Many hosts already advertise CloudLinux as a way to show higher stability. And many resellers recognize CloudLinux as a stability factor, and only want to be placed on servers with CloudLinux.

Hmm… that’s great. This means that ClouLinux reached a level of reputation which is making it something like a standard in the Linux hosting market?

I believe so. Lots of people recognize the name now, especially among cPanel hosts.

I have met with the executives of many web hosting providers who have deployed CloudLinux and are happy about it. My personal opinion is that CloudLinux is going to become or even has become a standard in web hosting industry and this is not a compliment, because I meant it. I know all customers are important and that you might not want to point attention to any particular hosting provider, but I’m curious who was the first hosting provider to buy and deploy CloudLinux?

We had several running it at pretty much the same time. uk2 was one of the first ones.

This is interesting. Does CloudLinux fit to their OneApp Cloud platform? Is it integrated with it?

Sure. OnApp comes with CloudLinux template, and lots of hosts who use OnApp, also use CloudLinux

You now, when I do these interviews, my objective always is to show to the B10WH.com readers, who’s behind the technology. So let’s talk about you. Are you graduated in computer science and how important was your education for your today’s business?

I was doing CS degree, but I never graduated. I started PSOFT instead. The education was pretty important, as it gave me enough knowledge to understand underlying technology.

It is funny. I know many fine professionals in this industry who are either top executives or owners of popular brands and did not have time to graduate because put all their energy in business! What does your wife says about that?

My wife just completed her Phd, and thinks it is a total disgrace that I left college :)

You know, the smart people who do PHd’s and the university professors should always remember that there is a real business that support in academics and the universities.

I think it was a mistake on my part to abandon college. It wasn’t the best decision for sure.

You told me once you have 3 kids. On which side of the technology business do you see them – as consumers or as professionals?

I will let them decide!

Someone might say it is irresponsible not to guide your kids ;) but the truth is that you are probably a very good father, if you want them to choose by themselves. Most parents don’t do this?

I don’t know, but I think it would be irresponsible to decide for them. It is their life, and they should have a chance to make their choices. Of course they still have to get college education, and I will have some troubles explaining them why it is a must have.

How far will you go with CloudLinux. Which direction is it going to go. Will you develop it more like an OS (Os itself) or it will be an application for the Red Hat family operating systems. Or you are going to try building any kind of one-stop automation solution for hosting providers (excluding the control panels, as fas as you said you are not doing control panels anymore)?

CloudLinux is an OS, it is a fork of RHEL, but we plan to keep it as close to RHEL as possible. The goal is to make it the best OS for Shared Hosting companies and we are concentrating solely on that.

Can anyone install it as stand-alone OS on a server or they need to have a RHEL OS installed on the server first?

Anyone can install it from the disk (we provide ISO image), though majority of people have pre-installed CentOS, and convert instead.

We are speaking a week prior to World Hosting Days conference in Germany. What do you expect from this event. And where CloudLinux is more popular by the way? Is it in the United States and Canada, in Europe or Asia?

CloudLinux is most popular in US, UK, followed by Asia and Eastern Europe. We don’t have lots of penetration in Germany and other western European countries, as that market is prefers Debian & Suse – which makes it more difficult for them to switch to CL.

WHD looks very exciting this year. It sounds like it is going to be biggest hosting event ever, and we are looking forward to meet our existing and future customers.

Thank you very much for your time Igor. I’m speaking to you in 2011 and I hope that when we’re doing the next interview CloudLinux will be even bigger and the OS will become a true standard in Shared Hosting.

tatiana-shaidorova-ispsystemI have made myself known with ISPsystem during the HostingCon 2009 conference in Washington DC where the company was among the Silver Sponsors. The first thing I that made a difference was their logo. I like it and It made me to pay some attention of this software producers. When I went to their website I’ve found that they have complete web hosting automation software line. Then I got in touch with the company asked Tatiana Shaidorova to present ISPsystem.

Hi Tatiana, good to meet you. Your company produces web hosting control panel, VPS management software, dedicated hosting system, DNS manager, IP manager and even a billing solution for web hosts. This is quite impressive, but shall ask you isn’t it too risky for any software developer to compete on any of these niches in the hosting industry? Why didn’t you focus on any of the above mentioned markets?

Our mission is to provide and design the web hosting automation software complex. The core of the company is a dedicated team of highly skilled programmers who work hard at fulfilling this mission. It is our advantage over competitors. Our products are integrated with each other. So it is very convenient for clients to use web hosting automation software line of one developer.

Which us your best selling software product?

ISPmanager is the best selling product. It is obvious. The hosting control panel is the most useful software for hosting automation.

I have found that one of the reputable UK hosting providers UK2group already offers “ISPmanager PRO”. So is ISPmanager the most popular one? How many customers do you have on the UK and European market?

As I mentioned before ISPmanager is the most popular one among our web hosting automation software line. We are novices on UK and European markets. But I am proud to say that we already have a lot of customers on this market. Our products are the most popular on the Eastern European market (Russia, CIS countries). We have been on this market for 5 years. ISPsystem software has been pushed on international markets only for a year. It is not a long period. But we have obtained the results. Our client base increases every day. ISPsystem software is gradually becoming worldwide products in hosting industry.

There some differences between web hosting markets in Europe and North America. In U.S. Shared Hosts sell unlimited, the Americans prefer to use more cPanel then Parallels Plesk panel. However Parallels are stronger in Europe. What are your advantages and how do you compete each of these software producers? If I was prospective client what would you tell me to make me to sign with you?

ISPmanager is easy to use and fully featured control panel with the user friendly interface.  It has a set of advantages. One of the greatest advantages is high efficiency with low system resources consumption. ISPmanager is easily installed without changing operating system configuration. Also the control panel can satisfy the requirements of both novice users and advanced server administrators. It provides multi-level access to administrative features for increased management flexibility. ISPmanager is updated regularly. We have a reasonable price policy with progressive discount system. I think these are our main advantages.

Let me now ask you about another product of yours – the Reseller level of ISPmanager. How important is this software application for you. Does it allow you to get more web hosts as clients?

Our Partner Program is very attractive for our clients. Partner Program includes low prices and flexible progressive discount system. Surely, it allows us to get more web hosts as clients.

You have said that your company has already debuted a Windows version of ISPmanager. Do you think that it will become more successful that the Linux one?

It is very difficult to predict what will be more successful – ISPmanager for Linux or for Windows. The Windows-based hosting market is currently developing. According to our observations, Microsoft is doing its best to develop the Windows Platform. At present, there are not so many Windows-based products. So, we hope ISPmanager for Windows will be successful on its niche in the hosting industry. We have already launched only test version of the hostign automation software for Windows. Now we are waiting for client reviews and wishes in order to improve ISPmanager for Windows.

I have reviewed your Virtual Private Server manager called “VDSmanager”. Can you please explain how do you integrate this virtualization technology with OpenVZ and Xen?

VDSmanager runs on two different operating systems – FreeBSD and Linux. VDSmanager for Linux is a user friendly web based interface that enables to create and manage different virtual machines based on popular server virtualization technologies like OpenVZ and Xen.  Xen and OpenVZ don’t have GUI. So VDSmanager for Linux is the best solution for VPS management using OpenVZ and Xen. VDSmanager for FreeBSD is available in two versions: VDSmanager and VDSmanager-SMP. VDSmanager is installed on a mono core processor machine. VDSmanager-SMP on multi-core CPUs.

Which software product of yours is most interesting for the web hosting providers?

It depends on kinds of web hosting business that hosting providers are going to render. Solutions for Shared Hosting – BILLmanager, ISPmanager, DNSmanager, IPmanager (optional); Solutions for VPS Hosting- BILLmanager, VDSmanager, ISPmanager, IPmanager (optional); Solutions for Dedicated Server Hosting – BILLmanager, DSmanager, ISPmanager, IPmanager (optional).

I’m interested to learn more about DSmanager. You promote it as “absolutely unique solution”. I didn’t see many similar software solutions. Can you please tell me more about DSmanager?

Yes, DSmanager is the absolutely unique solution. There are no many similar software solutions. DSmanager is a Dedicated Server management system. It provides centralized management of dedicated servers, allows minimizing connectivity, hardware and operating system installation, support, maintenance expenses, and maximizing the uptime of the network. DSmanager makes the process just a few clicks away.

DSmanager advantages:
• All dedicated servers are stored in a single base. The search for servers can be performed by their type, operating system and location.
• Users can install operating systems, reboot the servers, connect and disconnect to the network via single control panel.
• DSmanager supports power and network switches, enabling to use them with dedicated servers, once they are registered in the system.
• The panel can be used to automatically assign IP addresses from a pool of available IP addresses, simplifying their operation.
• Multilevel permission system: Admin, Reseller, Dedicated Server Owner.
• Open Application Programming Interface (API) enabling to use all features of the control panel, to integrate with various billing systems, etc.

If you are focused on Dedicated Servers lease and Server Collocation, DSmanager can help you to automatize business processes and provide new services to your customers.

Some software producers sell support, others include a basic level of support in their service plans. Please tell me how do you provide support. It says 24/7 on your website, but do your customers shall pay additional fees to receive technical support?

Our support is 24/7. In all cases when a license is ordered by the User directly from ISPsystem without participation of the Partner, technical support of the Software Product is rendered in full scope free of charge (additional works and services are paid for separately).  In other words, in most cases support is free.

Your pricing is in Euro. Do you sell in euros on the U.S. market and how do you deal with the weak dollar if you need to sell the software licenses at the same price in USD?

Minor changes in the dollar exchange rate are not so important for us.

Do you have any plans to enter in the Cloud computing market and if “yes” what kind of Cloud software would you have?

We are planning to go forward in this direction. But now I can’t say anything about it.
