Why do you need to go for VPS hosting? And the advantages and disadvantages of going with VPS hosting.

There are various topics we are going to cover in detail about VPS hosting.

So let's say what the topics we are going to cover in detail today are!

We are going to see what VPS hosting is? And why virtualization technology is there? How the virtualization technology came, and what are the technologies available?

How is this shared hosting different from VPS hosting?

What are the VPS technologies are there?

When should you go for a VPS hosting?

How to set up a multiple VPS server for a single website?

Advantages and disadvantages of the VPS server!

How to buy a VPS server?

Plans and options available for your VPS hosting.

How to manage your VPS hosting?

So once you have read this article entirely and I am very sure that will have complete knowledge about VPS hosting.

So this is how virtualization technology looks like that!

See here, in this case, what you see is a typical dedicated server! Without any virtualization.

What Is VPS Hosting?

Here, in this case, a physical is there on top of that your operating system runs like a Linux or Windows, and top of that like a Linux kernel is there properly, you can say that Linux kernel-related library on top of that your application is running.

So the complete everything is only one server, one physical server, one operating system.

This is a dedicated server, or you can call it has a physical server.

Here comes the virtualization, so here this is a virtualization technology that is a kind of a layer that you can say that based on hypervisor technology.

Hyper visor in a sense is a kind of virtualization layer this your physical hardware or physical server where on top of that you are running an operating system, and on top of that, you have hypervisor like KVM even hyper V is good for Windows-based dedicated server and VM ware here as you can see here on top of the hypervisor multiple VPS this is the virtual server.

This is one virtualization this another virtualization server; this is another virtualization server.

Like this there can be maybe about 100, 50, 60 or any number of virtualization server can be created.

This is called a kind of a hypervisor or virtualization technology, and there is another virtualization technology that is called container-based virtualization technology, in other words, it is based on operating-system-level virtualization like otherwise, you can call it has kernel-level virtualization.

In this one, you will have a bare metal server, physical server; on top of that, you will have an operating system; all this container virtualization technology will use the operating system from here, which interacts with a physical server, will have only one kernel.

Kernel means the core of your operating system, so it will have a one only kernel, but it will have a different set of an OS's Here OS 1, OS 2, OS 3, But what is the difference between this and this here even the operating system is also kind of virtualization, operation remains different. But the kernel remains the same.

This is called container-based virtualization technology.

Compared to container-based technology and hyper V based, both have some advantages and disadvantages.

So basically, in brief, container-based virtualization, technology has some kind of speed advantages compared to this one, here this technology has better performance, or it will not have a noisy neighbor problem.

Ok so this is an example of hyper V virtualization here as you can see this is your hyper V manager, hyper v virtualization manager, here whatever you see is here its all kind of virtual machines and what is the status of all these virtual machines, how much CPU has been utilized, how much memory is assigned, and this is the uptime.

So if you want to create new virtualization, we will do it new, or it can be done automatically using APIs.

Here this is another example of VM ware.

VM ware is one of the most popular virtualization technology in the world. And here, you can also create a new VM, also register a VM, and these are the virtual machines, what is the use time, and what is the operating system running what the hosting CPU, memory, and everything you can check it is.

This is how the system administrator operates the virtualization technology.

Why virtualization technology when we have a dedicated server?

See Here this, and there are some reasons why this virtualization technology has become so popular in the world.

For example, when we have a server.

The server may have around 512 GB RAM.

Even 1024 Giga of RAM cloud be there, or the CPU that is number of CPU can be 16 core or 24 core or even maybe more, but when you are running one single dedicated server, the all the time the resources of the RAM and CPU may not be fully utilized.

If you are going to run only one server, that is why what we do is we split the servers of the single dedicated server into multiple OS like 1, 2, 3.

So at any given point of time, all the OSs out of all the OSss some OS or some may be few or 10 or 20 OS will always start utilizing your CPU and RAM to the maximum extent.

So that we can get the maximum output from single hardware, and when you have virtualization technology instead of having a ten dedicated server, you can put all the ten servers in one physical server and make it has a multiple visualized server.

So that you occupy very less space in the data center and it becomes less cost, and another very important point is in terms of when you have a hardware failure or when you have a disk failure or some issue with your hardware, and your dedicated physical server is sometimes booting it may take up to 4hrs, 8 hrs, 12 hrs, to bring up your server, So during this 12 hrs time you are given 24 hrs time your website or your business will be down in dedicated server, but when you have a visualized server if you have a recent copy of the virtualization server you can immediately move the virtualization server in another hardware and bring up your website in less than a 15 mins or in 20 mins time.

In virtualization technology compared to shared hosting, you will have full control over your server, and it is easy to migrate your visualized server from one location to another from one service provider to another one.

In terms of disaster recovery, if you are going to virtualization or your technology, you can get recovery from the disaster even within a minute! 

That is possible the technology has become so advanced nowadays that within a minute you can recover from your disaster.

And virtualization it is very important for security to let me tell you how it is important for security lets to say that you are running a business - and the business has around said that ten different blogs, for example, bigger eCommerce organization in eCommerce organization you have a database, you have a login system, you have category management, you have product listing, you have payment gateway like this there can be maybe 10 or 20 different models or 10 or 20 different servers running.

So it is very easy to secure each and every server separately rather than lets, say that one out of these server one server is compromised, then still you can produce the remaining servers.

So security becomes easily with that scalability, so in virtualization, you can keep creating the virtual servers within a minute, or within second also, the scalability has become so easy for virtualization technology.

And using virtualization technology, you can create a high available server in terms of web or data-based server, so that you can provide high uptime.

For example - if you are going to run only one dedicated server, which is where your data based and the webserver is running, assume that there is any problem with that particular dedicated server, then your complete server will be down.

But you can create multiple web servers or multiple visualized server in a different physical load and run multiple replicas of your web server in 4 or 5 different visualized hosting servers, so even if one particular server is going down, then the remaining 3 or 4 servers can be running.

In a virtual server or in one physical server, your resources are shared among a few people, maybe around 5, 10, or 20 people.

But in shared hosting, what happens right, you will be in kind of more than 100 or 200or 500 websites will be shared on a single server. 

When do you go for a VPS hosting?

Let us say that you are running a shared hosting, and the performance is not good, and then you can migrate to VPS hosting.

If you want to install any specific applications which are not allowed in shared hosting, then you have to go for a VPS hosting where you get full root access, and we can install any desired applications.

For some reason, you may want access to the services which are running in a server, and if you have root access, you will have complete control over the server!

So, in that case, you can go for a VPS hosting.

If you want a private server, which is where you are not willing to run your website, which is shared by multiple people, then, in that case, you have to go for a private server.

See this is the example of how to set up your VPS server with high availability?

For example, in this case, if you are going to put your web server and a DB server in a single server, then most likely, this server is going to have any problem, then your website will be down.

In this case, this is very much useful case when you have a VPS server, but it is getting more hits, or it is getting more request, and your VPS server is not able to handle the request, and there is a delay, or if it is slow then, in this case, you can run your web server in one VPS server and DB in another server, so that the load is shared between 2 servers so that the performance will increases.

Here is it another example of providing a kind of high availability, so whenever anyone opens your domain name like for example mybuisness.com, then the request comes to this load balancer first then it goes to here and here, again the web traffic is shared between 2 servers, so it becomes kind of a better performance.

In this case, we have shared the load with three different web servers but using only one DB.

If you want to provide even better architecture\ you can have multiple DB like this all these multiple DB here. These web server will interact with the DB 1 here, DB 2, and DB 3, this becomes a kind of truly achieve.

Advantages and Disadvantages of VPS Hosting

What are the advantages and disadvantages of VPS hosting? You get a guaranteed CPU and RAM, a complete OS with full root access, you can install any applications or do whatever you with the server, which is not possible in shared hosting, less rent compared to the cloud or dedicated, on failure you can take recovery quickly, you can migration easily security, availability, manageability becomes easier, you can setup Apache and the snapshot is available, Snapchat means, for example, this is one of the very good points about VPS, let us say that you are a server the same running copy of your server can be taken a duplicate copy which is called has snapshot!

If something goes wrong with your server lets say that your OS is crashed, your DB is crashed something goes wrong you can recover from your Snapchat very quickly and run the server immediately, then access to root level or root-level access, such as you have access to the servers like Apache, email servers and network.

Sometimes what happens you become a kind of a compliment or certification which has to be followed, if you are going to run any financial instantiations, sometimes those things are not possible with shared hosting.

You have either go with a dedicated server or VPS server.

The disadvantages if you see with VPS, it is not much with the VPS server but, still, maybe I say it is not powerful like a dedicated server, but still, you can achieve the same performance by having multiple servers.

Like sometimes some financial institutions, not all, they insist on having a dedicated server.

There are the disadvantages I see, but other than that, there are not many disadvantages with VPS servers.

How to buy VPS servers?

And we will check here how to buy the VPS server, what is the thing you have to check, to see before buying VPS server and plans and options available.

If you don't have an SSL certificate, what happens?

Let's say that SSL certificate warning - you will get a warning message like this, and customers will walk away from your website.

They will not go to your website, and you will lose business, so it is very, very important to have an SSL certificate, then what to check?

You just check it whether you get all these things from other service providers if you get all these services to make sure that the servers are fast, and servers have to be located in Indian IP if you are going to use the Indian IP address it is going to benefit you in Google ranking and SEO and it will load faster.

And make sure that they provide good support, these are the things that you have to consider it!

If you are from other countries like, for example, the USA or Europe, then we recommend you to buy from the same country, to make use of speed and IP address advantages.
