windows vps hostingRecently one of our readers asked us to post an article about the benefits of Windows driven VPS hosting. Since we’ve been looking into provision of this service as well, there was some interesting information gathered and we would like to share this with you. We thought that showing both upsides and downsides of this type of hosting is more fair. Sure, this article is posted from our point of view, so it reviews peculiarities of Windows hosting in terms of use of VPS-hosting specifically as a platform.

How is Windows run on VPS servers?

Running Windows on VPS usually implies the use of two types of virtualization technologies – XEN – the technology, generally applied in creation of fully virtualized VPS platforms and Hyper-V – special virtualization system, developed by Microsoft to run Windows VPS server only. XEN is known to many of our readers – this virtualization technology allows to create and manage virtual servers keeping them completely isolated from each other, while using same hardware resources by different system kernels – each fully virtualized environment keeps the system with its kernel that addresses to the layer of virtualized hardware.

As for Hyper-V – this technology needs some description. In fact, it is a hypervisor that works on the basis of partitioning with at least one parent partition that has access to hardware and can create child partitions that host guest OSs within virtual environment – just like XEN and its interfaces. But if you take a closer look, you can see that Hyper-V is a version of core installation of Windows Server 2008 with virtualization support – which makes it look much like OpenVZ that utilizes modified Linux kernel. Thus, it is fair to call it a symbiosis of two technologies.

What is so special about Windows VPS Hosting?

VPS as a platform to run Windows on has become a real discovery for many users who needed Windows-based hosting but could hardly afford a dedicated server while experiencing issues with shared hosting, run under this OS. Indeed, using Windows as a server OS and namely for hosting needs is quite troublesome – initial resource usage is higher than that under Linux, disk usage policy and work of the disk subsystem is more complex, and full functional access can be achieved only by establishment of remote desktop connection (RDP) or a control panel. The latter aspect caused the biggest inconvenience, since shared hosting users are not usually provided with RDP access while the control panel functionality is limited so, that the lack of privileges makes the use of many tools impossible.

Use of VPS hosting has solved many of those problems – VPS carriers with large amounts of RAM allowed to delegate resources that are enough for the system to operate with additional software and cover the loads created by resource intensive programs (e.g. Microsoft Exchange server); RAID hard disk arrays + virtual disk partitioning allowed to minimize the I/O loads and increase the read/writing speed. Finally, a VPS allowed to create isolated environment, which enabled the users to manage their servers under “Administrator” privileges.

What are the downsides to keep in mind?

Besides the obvious upsides of Windows-based VPS hosting, there are, however, downsides that should be considered while making the choice. First of all the price – when it comes to evaluation of Windows hosting in general and its hosting on a standalone server in particular, all licenses, starting from the OS itself and all software, seem to cost an arm and a leg. The server is not going to be cheap as well – as mentioned above, Windows requires more resources, so the least powerful virtual server you will need is a XEN-based VPS – which are more expensive than those under OpenVZ – with 1 GB of RAM at minimum (you can find plans with 512 MB of RAM offered, but there won’t be much resources left to operate with). A Hyper-V based server with same resource rates will grant you more stable hosting, but it is going to cost more.

Mentioning this downside we don’t mean that the pricing difference is going to reflect in tens of dollars compared to Linux VPS hosting, but this may make some users think, whether they need it – at least those, who are not sure, if they are going to prefer ASP and .NET to PHP. If you are sure about the use of Microsoft software, here are some more tips on what you should be careful about.

Accessibility. You may be happy about having RDP and control panel access to your server – both provide clear intuitive interfaces, the former actually makes you feel like sitting at your home desktop, but are those means actually enough? If your server gets too overloaded, you may not be able to access it to reboot it, so you will need to send a support request which definitely causes a time loss. What you may make sure about before choosing your Windows-driven VPS host, is if they offer remote reboots from the host’s client panel – this may save your time.

Monitoring. Unlike Linux-based VPS servers, those running Windows need more severe monitoring, which may result into either bigger expenses – so you will need to hire an administrator or involve your host’s support team – or stresses, caused by constant inspection of your server’s state and investigation of issues it has or may have in future.

There are even more aspects, related to OS Windows itself to be kept in mind – security, as Windows is quite vulnerable; software-related; usability-related and others. So it is fair to get back to the question, whether you really need it. Many webmasters who are asked to create a site to work on a Windows server usually ask this question. And when they receive a solid “yes” they want the project to be described as clearly as possible. Thus, if you imagine your project well and see the full picture of how it is going to be run and why exactly it needs Windows, you are on the right way, and we hope, that your experience in this is going to be positive.

VPS hostingAfter we have delivered you numerous articles on different aspects of VPS hosting, we’ve noticed that we need to get back to this topic again. Once again we are going to talk about the problem of choice of a VPS server. This time we are going to take a look at this question under a different angle – let us share some interesting tips on how to tell if what you see when checking out the feature/pricing page of your potential VPS host is what you are going to get. While introducing you choice-making tips in our previous articles we usually referred to the technical aspect of VPS hosting, today we are going to analyze the VPS hosting from the point of view of a customer.

How much RAM do you get in fact?

When you see a 1 GB VPS plan at a very low cost, don’t be too fast in making optimistic conclusions. Check if this entire amount is guaranteed RAM. The best option is to contact sales support – then you are going to have a proof – a copy of your chat or email. But if you don’t have time for those checks, there is a quick way to find it out on your own – check the virtualization type used by this host. If it is XEN – be sure the entire 1 GB of RAM is guaranteed. If they use OpenVZ (the hosts that use it often say their VPSes are powered by Virtuozzo), there’s a risk, that their pricing provides the combined amount of RAM – guaranteed + burstable (RAM, that may be allocated only for a short period of time and thus – not constantly available). Since RAM is the main feature of any VPS server, this should one of the first points you verify before moving any further.

CPU units

Checking out pricing of some VPS hosts, one can find such feature as CPU units. This parameter shows the CPU frequency, available for the given VPS. Although it looks rather informative and lets the potential client compare the offered plans in more details, it’s not quite a correct way to represent VPS CPU specifications. To find out how powerful the CPU of the given VPS is, you need to know, what number of cores the entire VPS-carrier has, what their frequency is and how much of this power is delegated to the specific virtual machine – the latter factor depends on performance priority.

If you don’t know, how to interpret this information, you can simply ignore it. If you do need the details, you can have a brief consultation with the sales department of your potential host. This will let you find out the specifications of the carrier. The more powerful it is and the bigger the plan you are looking into, the more powerful your VPS is going to be.

Disk Space

Since VPS servers are usually offered as a fast solution that is cheaper than a dedicated server, those are not designed for large data processing. The minimal plan at some VPS hosts may offer as little as 10 GB of disk space. If you are going to host a few web pages, it’s alright, but if you work with email and databases, you need to consider disk space allocation rather carefully. Now let us count what you have in the end – after your server is setup, the system may take up to 2 GB of disk space. Any backup you make is going to create a file of the size approximately equal to the size of your /home directory. Not that much space left, isn’t it? That is why another Gigabyte of your virtual HDD may become vital. Well, it can also be taken by swap. According to the architecture of OS Linux, swap is a fixed disk partition, not a file, unlike on Windows – therefore, before you order a XEN-based VPS, you need to consult sales department first, to find out whether /swap is counted with the disk space offered or not.

Summary

If you want to be completely sure about your future VPS host, you need to find out as many details as you can before you actually sign-up for their services. Your potential host may not list everything on their web-page, it’s alright, but their sales and technical team should always be able to explain these or those aspects of hosting with their company. If it happens that some of your questions remains unanswered, you have serious reasons to not consider this host.

Not that long ago we published an article introducing you into cloud hosting. This relatively new, yet powerful and promising technology becomes more widely used in hosting of small and medium online projects day by day. It means that this kind of hosting services gains users trust and requires less technical skills than one might think. Additionally, it makes prospect customers expect further price reduction, which in turn may increase the sales of this product.

If you want to make sure that all your plans regarding your hosting ground get realized, it is vital to do some pre-sales work targeted at finding out as much technical information as possible. Many things about the technology in use are usually available in extended feature list of packages offered by a hosting provider, at their corporate Wiki or FAQ documents. Today we are going to talk about the primary parameter to look after while choosing your cloud host – platform.

Choosing The Right Solution

Last time we spoke about making a choice of a Virtual Private Server in terms of the configuration varieties. Today we are going to continue our research and tell some useful facts about types of websites, applications and services one may use on a VPS and the related dependencies.

There are many types of websites and online services on the Internet that differ by system requirements, performance or way of work. Sure, most websites work with a standard configuration and software set but some websites and especially services need an accurate configuration pick and fine software tune up. In this regard we are going to list the most popular services and applications in the today use and find a correspondent VPS-based solution for each. Well, let’s start.

1. Email and ftp transfer services

Email and FTP transfer

Email and FTP transfer

VPSes are widely used for establishment of certain separate services on them. If you want to get a simple email or ftp server which would need no constant web-access, you may get the simplest custom configuration of your virtual server, which would include just the OS and basic mail exchange/file transfer services. If you wish to run some additional scripts, you have LAMP installed as well (you will anyway need Apache in order to provide webmail access or check the uploaded files via web). In such cases the control panel is not essential (some users do not even include it to their orders) what makes the choice of the OS not crucial as well. Neither is the choice of the virtualization type. Such web-inactive resources do not usually require severe monitoring or many maintenance efforts, especially when strict connection quotas and transfer rate limits are set. CPU/RAM parameters may also be minimal, however those exactly parameters will let you define, which limits to set. Read the rest of this entry »

Choosing The Right Way

When website owners decide to purchase a Virtual Private Server for their websites, they are often concerned about its configuration. If upgrading from a shared hosting account, a user may pick a too weak server and put it down right after the website launch, as virtual servers do not have such strict limits on resource usage set, as shared ones do.

If someone is purchasing a VPS at once, without having the site actually tested elsewhere before, its owner may pick a wrong software configuration and not even have the website started (we don’t think that error pages hosting is funny or profitable).

A fair question is “Which VPS configuration to choose to provide my website with the most optimal hosting solution?” Here go the answers.

VPS Configuration Types

Virtual private servers differ in their configuration by many parameters. Those usually depend on their vendors’ likes and commercial interests; presence of trained personal, able to work with this or that software; welfare and funding, etc. Studying the market of VPSes we can define the following main configuration options: Read the rest of this entry »
