As the name indicates, a server is an advanced equipment store having virtual hard disk that hosts the web page files under one domain so that people can see them on the internet.
For example, a server is a computer which has certain characteristics, folders in them and are hosting the files under the domains that allow your site to be found on the net.
It was once thought that only experts in programming and internet acquired a server, but this is a myth and that all people can access them either by necessity or as a source of business, because if we have to server hosting, can sell and make money.
There are many companies dedicated to supply servers and there are many types of plans. This depends on the features that people need like storage space, memory, or depending on the processor speed needed.
There are many types of servers but when we talk about VPS server, it is a virtual private server which is dedicated to specific tasks and improve the performance of hosting, with controlled access.
Through this the user has all the features and resources of advanced equipment, ie where you can manage your domains and share them with other people but with controlled access.
Characteristics of VPS Hosting Servers:
The characteristics depend on the plans held by the company and on budget and the needs of customers.
VPS Servers Are Available on Linux and Windows
Advantages and recommendations
Among other advantages, VPS Hosting has become the best alternative for people who do not want a shared server, or a dedicated server.
For this reason I invite you to purchase one of these and not get left behind in the way of having your own hosting and domains in the best way, a story in memory, speed and security, and as I mentioned before, in this way you can also obtain new sources of revenue.
In our experience, every day we encounter dozens of companies who waste their computational power, their server to go to really provide a few thousand visits, to a very high cost. Legacy of the past, the use of dedicated servers is often not optimized on servers with different cores and GB of RAM, you are finally able to serve a few hundred visits , below is the real potential hardware.
The reason: These servers are not well configured, do not have any type of optimization, and often result in damage to the company where they slowly serve web pages and the hosted websites
There are a large number of dedicated servers or colocation who have several years of service and have a very high operating cost for their clients. We’re talking about machines that have processors with minimum 2 Core , 2 to 8 GB of RAM , but in fact mount older motherboards and have a high consumption compared to newer servers.
These servers should be replaced, and the best choice, to date, almost always is to use instances of cloud computing, perhaps provided by the same provider from whom you purchased the dedicated server. The substitution instances of cloud computing does not necessarily mean spending more, in fact, very often the server we are going to replace, being physical, are redundant with other machines, increasing the power consumption and cost: this need with the demands of cloud computing is not always necessary, since many vendors offer HAS base on virtual instances and the lack of having RAID or other common systems on the physical servers to increase the reliability of the system.
Matching Resources And Performance: Optimize Server Daemons
Your server does not necessarily need to be replicated in the cloud with the same resources, we have already said that the main problem that is encountered is the lack of service configurations within the server and the lack of a general optimization of the machine. This leads to a high consumption of resources, not justified.
What Are The Services That Most Affect Performance:
Webserver : Most have a view of the servers have an installation of Apache Web server, but this is not the best solution for all your needs. Apache has become one of the most popular, but nowadays there are better solutions such as Nginx and LiteSpeed, solutions that are configured for reception of high traffic loads.
Database : In this case we know that the problem is almost always MySQL. It is a database that does not scale quickly and which requires a configuration for ad-hoc environments which may vary according to the type of site. In these cases, our advice is to proceed first to identify what is the actual load on the DBMS, performing analysis using specific tools and proceed to the configuration file of MySQL: use successfully for some customers even Percona MySQL , tools that we repeatedly reviewed and for which there are several applications which are already ready for configurations.
The database is definitely one of the most delicate and critical for those involved to migrate its infrastructure with a performance optimization. At present we found that the greater improvement is achieved initially by an ad hoc configuration of machine and balancing resources properly if the machine takes care of serving only the DBMS, and going to provide a configuration tailored to the individual service installed, precisely with the help of a prior analysis of the problems. Very often the database is a “victim” of queries in poorly designed applications, a problem which can be solved easily without putting hand directly to the application code.
Load Testing And Performance Testing : Once a server is put together, the job is not done, we can even say that this is only the first step. What is needed is to see how does the server and its configuration under “stress”, going to simulate a load as usually we do in our reviews. This allows you to see if the work done during the configuration is correct, and especially how it responds to our server in the event of a high peak of requests: usually both hardware and software configurations must provide the level of “tolerance” that help the system administrator to exploit the resources for the management at the peaks.
In 2012 the bandwidth used worldwide is worth growing, because users who access the Web are growing in number and data center service providers, as well as ISPs providing connections to homes and businesses are faced with an ever increasing demand for bandwidth output from their servers.
The bandwidth, which we will cover in this article as a monthly traffic, is surely one of the parameters of interest when one talks of a webhosting solution. Whether it’s a shared hosting solution or a dedicated server, your ISP gives value to bandwidth, which indicates the speed at which our website may provide content to the outside users, and a value of traffic per month , Instead it indicates how many gigabytes does our site use every month. These two values are in fact relevant, in fact if we multiply the bandwidth available to us for the month of use we get exactly the maximum monthly traffic that we use for our web site.
Many customers, when choosing a solution for a new web site, or already launched website, find it difficult to estimate how much bandwidth is needed for their site, and therefore rely on solutions that are often not suitable. In this article we see, briefly, how you can get an idea of bandwidth consumption and how to predict the increase in the short term.
The traffic monitoring carried out by our web site is crucial for several reasons. The most obvious is that many hosting solutions charge the cost as per additional GB over the threshold limit. If our plan includes 20 GB of monthly traffic, and the use is 25 GB in a month, then we will have to pay extra amount to the provider in excess of that 5 GB bandwidth.
The same applies to the VPS and dedicated solutions where the charging is often even more stringent. Monitoring of the traffic allows us to understand the days with more visits and requests from users, and may be the wake-up call to see if the traffic generated is not entirely “normal“, but produced from attacks on our web site (DDOS Attack) or by search engine bots or other organizations that require our pages all the time.
The speed will change significantly if the bandwidth is completely used: In this case, the provider does not provide us with tools to understand how much bandwidth we are using in real time, except in the case of dedicated servers and VPS. Many shared hosting accounts have such a dedicated bandwidth of 512 kbit / s or 1 Mbit / s, while other vendors prefer not to expose this value.
As previously mentioned, the value of bandwidth is a parameter connected to the monthly traffic, however, it has a greater importance in some cases because it allows to understand exactly how many visitors we can accommodate simultaneously online, with a continuous request for content from our account or server. Take, for example to the streaming services, or to services providing multimedia content, in this case it is essential to have a value guaranteed bandwidth.
If our website is already online, the first thing to do is have an idea of the current consumption that we are producing. In this case we take a look at the statistics of the web server, and more importantly, we cannot use tools like Google Analytics, which do not provide information about the use of bandwidth.
Two tools that we can take into account are AWStats and Webalizer. These two statistics software are installed by almost all hosting providers which allow you to check the bandwidth usage on a monthly, daily and even hourly basis.
Many hosting providers, especially in the case of dedicated servers and VPS, from their control panels provide the ability to monitor the traffic used to be able to get an idea of monthly consumption. The control panels such as Plesk and cPanel provide the ability to monitor the bandwidth usage per web site, on a monthly basis. Once we have a clear idea of the consumption of our website we can certainly provide the best future growth even and especially to move towards a web hosting solution that can guarantee the traffic without any problem.
Now that we have seen that we can use statistics to get an idea of the consumption of our web site, the question is trivial, as we do in the event of a new website. First we must understand what we talk about in detail: a website that was launched with much content online without any promotion on dedicated channels, it is hard to see thousands of visitors on the website daily.
Unfortunately in this case we do not have technical data: Study the impact of an online site meets several qualitative questions. If we plan an advertising campaign on multiple channels, we can now estimate a high number of visits (proportional to the number of channels and the channels chosen for ad), and if our web site relies solely on organic traffic and search engine traffic, we cannot get 2000 daily visits.
We can try to understand the consumer as well for visits: It is easy to “measure” the content. First we make our web pages and do an average of their weight. Today, a page can easily get a weight of 400/500 Kb: we know that in this case if you open it 10 times, we used 4 MB of traffic, if they are opened 100 times, 40 MB is used and so on.
With an estimate of the traffic generated from our website, on a given day, we must consider a number of additional variables: the majority of websites have days during the week where the traffic is higher, these are usually working days, but this pattern may change depending on the website. Like, the night of the Web sites are those where less traffic ever recorded. Once our website has been online for a few weeks we will have a clearer idea of the days with higher consumption and hours in which there is a spike in visits.
If we talk about solutions such as VPS and dedicated servers, then it is evident that the monthly traffic and bandwidth are values that need to be taken into strong consideration: providers set limits in terms of guaranteed bandwidth, such as 10 Mbit / s, and in terms of band burst, ie the quantity of excess bandwidth that can be used for a limited period of time.
If our server has dedicated 10 Mbit / s guaranteed bandwidth and 15 Mbit / s burst of bandwidth, means that for a certain period of time in the day we get to use the value of 15 Mbit / s.
Currently there are dedicated servers and VPS packages which are activated with flat rate, where they also have several terabytes of traffic including: in this case it is useful to understand what is the guaranteed minimum speed for use thereof.
In the case of shared hosting solutions: Nowadays many hosting providers do nothing but place the value of “unlimited” bandwidth that can be delivered out, a practice that may mislead customers as unlimited resources do not exist. This choice is due to the fact that most shared hosting customers have an average consumption of the infrastructure of the hosting provider. This does not mean that our web site can really accommodate millions of visitors, usually the contract of service raises this issue clearly and frees the provider from liability for the suspension of the service if excessive traffic is carried.
I was wrong. I thought that the “trend” is always to buy a VPS (Virtual Private Server, also called Virtual Machine, VM) was over and yet I cannot help but noticed that there are still a lot of people who still speak so much of the goodness of these solutions to shared hosting when it is no longer enough .
The VPS are nothing more than virtual machines created with different technologies, depending on the needs and the provider you choose, but from the point of view “operations” are real and their dedicated servers are only different in the eyes of the user in name, but with all issues involving the management of a server on the network, from its management.
Users have begun to compare VPS hosting plans with shared and reseller for some time: this led to these solutions because they offer to acquire the ability to manage more domains, to have a control panel other than the one we have seen in most other offers shared hosting and why it usually has a “full customization.” The “merit” is a lot of offers, not managed, they did seem really easy to manage your VPS, if not for the fact that these require knowledge and a management of shared hosting, even professional level, obviously not required. I try to clarify once and for all and then with a series of points about what gives a VPS and shared hosting one thing, trying to emphasize a line of confrontation between the two products:
Also suitable to absorb peak loads and important if it is a professional solution with high level.
I hope I was able to focus on what are the salient features of the two offers and why a VPS is a solution that is more complex to manage, justifiable only if the customer really needs.
Today, I will speak only of some advice on how you can make a better server backup of your own dedicated server or VPS. There is talk of unmanaged server, where the server is put online without any assistance and with a backup policy to be implemented completely at home.
Backup, really needed?
If your server contains only the files of little importance, websites of which you have made changes in years and years, then the answer is no. If you have websites and important files, then you must immediately count the cost of the server that must be added with a backup solution. The budget may be commensurate with real needs, and also varies depending on the frequency with which we want to backup.
The first step, I repeat, is to become aware that without a back up, our service should not go online. In the case of data loss we will not give any chance to get back online in many cases and many have to remain offline for a long time.
What kind of backup?
Run up the data on the same server that provides the service does not make sense , and in fact it is only useful if that backup is then immediately exported elsewhere, on other media. The best choice is to back up your server on another machine or even better on a service dedicated solely to the backup, which in turn has an adequate technical data protection.
If our business is important, it is better to start now to think of the redundant backup across multiple media: an online backup service at a special (sending via FTP or rsync) or through the placement of data on external media such as DVD or our hard drives in the office.
Usually other dedicated servers are chosen to back up several machines online, virtual and physical properties: it is not entirely the best solution, at least not until it is combined with other solutions (media). Better then to think of a dedicated external backup service, to another provider or directly online through one of the many services worldwide that offer backup space. The advantage is that in fact these services in turn provide data security systems and reduce the risk of loss or damage to the integrity of the data.
How often to backup?
Daily, weekly, biweekly or monthly?
All these options have a different charge, as do a daily backup actually means keeping multiple copies of data. Usually a daily backup is very useful for database and dynamic web sites that are updated daily, but of no use if our data is not updated frequently. The weekly backup is usually the intermediate solution, the one chosen most often for web sites and servers that contain a good number of GB of data and must be backed up with a cost, however small.
Cloud computing is the buzzword of the moment, but what does it mean? This is really ready for prime time, or you want to stay with VPS?
First, some definitions:
Head in the Clouds?
In a sense, cloud computing, is a grid computing that borrow the overall computing resources for application processing rather than local servers or user devices. This is an updated model of a supercomputer for the IT company of the people, promising trillions of calculations per second for financial services, personal data and a huge, immerse gaming network.
Cloud computing brings together a group of servers using (mostly) low-cost, consumer-level components of a PC on the network, the distribution of data crunching cleaning. Virtualization techniques can maximize Cloud computing power. Standards for the PC and network connectivity, and software do all the work. Now, cloud computing has become the hot thing, and its potential for accessing and sharing of computing power as a virtual resource, security and a scalable way, makes it attractive for large corporate data centers. It’s all pretty vague and uncertain, though, and early adopters need courage, as well as expanding budgets.
VPS Hosting, Tried and Trusted
VPS means virtual private servers, which is created on a special physical server in a data center. VPS essentially stand-alone server hardware sharing a single physical server, something like a dedicated server with its own memory, disk space, as well as the IP address. Since you can manually restart the VPS and operate as a separate server that can run your own applications. It is similar to dedicated servers, but closer to the cost of hosting plan, VPS servers can process requests for secondary business sites easily.
Each VPS account on the server, have its own partition, which allows them access to their own roots and bandwidth. This improves performance and allows users to run their own applications. VPS works like a dedicated server, in many respects, except when it comes to paying for them, since they are much cheaper in comparison.
Cloud computing is definitely the hot thing and there are couple of cloud hosting providers in India. Nevertheless, many experts believe that the term is a multitasking buzzword used to describe the confusing array of different technologies. Cloud computing term is used to refer to utility computing, network computing, software as a service “model, Internet applications, remote processing, autonomic computing and peer-to-peer computing.
There are people who believe that the term cloud computing is another key word used to describe too much technology, which makes it confusing for many. Cloud computing term is used to describe grid computing, utility computing, software as a service, Internet-based applications, autonomic computing, peer-to-peer computers and remote processing. When most people use the term, they can have one of these ideas in mind, but the listener can think of something else.
User forums filled with people who have a number of high-traffic Web sites with 10000 hits per day range, but if there is not high traffic, it is sufficient demand to justify the preparation of solid, capable VPS or Dedicated server. Some of these claims involved a huge cost savings from the cloud, but they show that there are usually standard monthly payments over the utility billing. It is obvious that at present the regular forms of hosting is cheaper to scale to enter a formula, then the lines will intersect and cloud computing will be a less expensive alternative.
The problem, of course is that, there is a lack of awareness. Some clouds providers have developed online price estimate tools like cost calculators, which will be considered with estimated bandwidth and storage needs that can crank out a monthly bill. That’s all you can do to get a cost comparison at the moment.
Cloud Hosting and VPS Hosting, both are Best…
Only factor matters is the Requirement….
