What is VPS Hosting?


Welcome to HostingRaja video tutorial. We are very happy to explain about what is
VPS hosting? Why do you need to go for VPS hosting? And advantages and Disadvantages of going
with vps hosting. There are various topics we are going to cover
in detail about vps hosting. So lets say what are the topics we are going
to cover in detail today! We are going to see what is vps hosting? And why virtualisation technology is there
how the virtualisation technology came and what are the technologies available? How is this shared hosting is 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 vps server! How to buy vps server? Plans and options available for your vps hosting. How to managed your vps hosting? So once you have see this video completely
and I am very sure that will have full and complete knowledge about vps hosting. So this is how virtualisation technology looks
like that! See here in this case what you see is a typical
dedicated server! With out any virtualisation. 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 a 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 virtualisation so here this
is a virtualisation technology that is a kind of a layer that you can say that based on
hyper viser technology. Hyper viser in the sense is a kind of virtualisation
layer this your physical hadware or physical server where on top of that you are running
a operating system and on top of that you have hyper viser like KVM even hyper V is
good for Windows based dedicated server and VM ware here has you can see here on top of
the hyper viser multiple vps this is the virtual server. This is one virtualisation this another virtualisation
server, this is another virtualisation server. Like this there can be may be about 100, 50,
60 or any number of virtualisation server can be created. This is called kind of a hyper viser or virtualisation
technology, there is another virtualisation technology that which is called container
based virtualisation technology in another words it is based on operating system level
virtualisation like other wise you can call it has a kernel level virtualisation. In this one you will have a bare metal server,
physical server, on top of that you will have a operating system all this container virtualisation
technology will use the operating system from here which is interacts with physical server,
it will have only one kernel. Kernel means the core of your operating system
so it will have one only kernel but it will have a different set of a 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 a virtualisation and the operating system remains almost same! Sorry operation remains different.but the
kernel remains same. This is called container based virtualisation
technology. Compared to container based technology and
hyper V based both have some advantages and disadvantages. So if you are going to cover it — it is going
to be a lengthy topic, so we will skip that! So basically in brief container based virtualisation
technology has some kind of a speed advantages compared to this one, here this technology
has a better performance or if will not have a noisy neighbour problem. Ok so this is a example of hyper V virtualisation
here has you can see this is your hyper V manager, hyper v virtualisation manager, here
what ever 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 utilised, how much memory is assigned,
and this is the uptime. So if you want to create a new virtualisation
we will do it new or it can be done automatically using APIs. Here this is the another example of VM ware. VM ware is one of the most popular virtualisation
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 is the hosting CPU, memory and everything you can check it. This is how the system administrator operates
the virtualisation technology. why virtualisation technology when we have
a dedicated server? See Here this there are some reasons why this
virtualisation 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 may be more but when you are
running a 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 maybe few or 10 or 20 OS will always start utilising
your CPU and RAM to the maximum extent. So that we can get the maximum output from
a single hardware and when you have virtualisation technology instead of having a 10 dedicated
server you can put all the 10 servers in one physical server and make it has a multiple
visualised 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 physical dedicated server is booting sometimes it may take upto 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 sever, but when you have a visualised server
if you have a recent copy of the virtualisation server you can immediately move the virtualisation
server in another hardware and bring up your website in less than a 15 mins or in 20 mins
time. In virtualisation technology compared to shared
hosting you will have full control over your server and it is easy to migrate your visualised
server from one location to another from one service provider to another one. In terms of disaster recovery if you are going
to virtualisation or your technology you can recovery from the disaster even with in a
minute! That is possible the technology has become
so advanced nowadays that with in a minute you can recover from your disaster. And virtualisation it is very important for
security let me tell you how it is important for security lets say that you are running
a business – and the business has around say that 10 different blogs for example bigger
eCommerce organisation in eCommerce organisation you have a database, you have a login system,
you have a category management, you have product listing, you have payment gateway like this
there can be may be 10 or 20 different models or 10 or 20 different servers running. So it is very easy to secure each and every
servers separately rather than lets, say that one out of these server one server is compromised
then still you can product the remaining servers. So security becomes easily with that scalability
so in virtualisation you can keep creating the virtual servers with in a minute or within
second also, the scalability has become so easy for virtualisation technology. And using virtualisation technology you can
create a high available servers in terms of web or data based server, so that you can
provide a high uptime. For example – if you are going to run only
one dedicated server which is where your data based and web server is running assume that
there is any problem with that particular dedicated server then your complete server
will be down. But you can create a multiple web servers
or multiple visualised server in a different physical load and run multiple replica of
your web server in 4 or 5 different visualised hosting server, so even if one particular
server is going down then the remaining 3 or 4 servers can be running. So this is how it is looks like. In a virtual server or in a one physical server
your resources are shared among few people may be around 5, 10 or 20 people. But in shared hosting what happens right,
you will be in kind of more than 100 or 200 or 500 websites will be shared on a single
server. When do you go for a VPS hosting? Lets say that you are running a shared hosting
and the performance is not good then you can migrate to VPS hosting. If you want to install any specific applications
which is 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 reasons you may want access the services
which are running in a server and if you have a 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 setup your
vps server with high availability? For example in this case if you going to put
your web server and DB server in a single server then most likely, this server is going
to have a 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
3 different web servers but using only one DB. If you want to provide even more 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 kind of truly achieve. 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 cloud or dedicated,
on failure you can take recovery quickly, you can migration easily security, availability,
manageability becomes easier, you can setup Apache and snapshot is available, snapchat
means for example this is one of the very good point about vps, lets 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 dedicated server or
vps server. The disadvantages if you see with vps it is
not much with vps server but, still may be i say its not powerful like a dedicated server
but still you can achieve the same performance by having multiple servers. Like sometimes some financial institution
not all, they insist on having a dedicated server. There are the disadvantages I see but other
then that there it not much disadvantage with vps servers. How to buy vps servers? And we will check here how to buy vps server,
