Cloud hosting is one of the latest forms of hosting which is taking the world by storm. So let’s know about it more:
What is it?
It works on the main principle which states that the resources which are required for maintaining the website are scattered over many web servers and are used as per a need-basis system. So your website relies on a group of servers, instead of just one, which works together. These clusters are then termed as ‘cloud’.
How many types are there?
- Public Cloud: Public clouds are hosted on virtual servers, where they pull the required resources from a cluster of other publicly accessible virtual servers. Similar public networks are then used to spread the data which are physically stored up on the shared servers that help from the cloud reservoir. In case there are worries regarding security- they have adequate security measures in place to ensure that all the data remains private.
- Private Cloud: It is advisable to use private clouds if security and privacy take more of a priority than others. These are ring-fenced resources, like servers and network and it doesn’t matter if it is located on the site or along with the cloud providers.
How do they hold up when compared with single servers?
Cloud hosting acts like an alternative for hosting websites on single servers (either shared or dedicated servers). It can be considered like an extension of the very concept of clustered hosting where multiple servers host websites. But in cloud hosting, the network of servers used are vast, as well as pulled from a variety of data centers present on different locations.
Cloud Hosting vs. Dedicated Servers & VPS
In the case of dedicated servers being compared to cloud hosting:
Cloud hosting is more reliable since there are multiple servers which can be used. This is in contrast to putting just a singular server to work. So, this kind of variety allows for more wiggle space during emergencies without heaping on more stress. But it should be noted that the price varies according to usage.
In the case of VPS and traditional shared hosting:
On one hand, the cost is low, but sadly, so is the reliability of it all. In the case of VPS, a singular server is divvied up into multiple parts and each such part is managed by a respective client.
How is Cloud Hosting done under Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) classifications?
PaaS: Here the user is given the software environment, using which they can install and develop the web application they want. It is also easier to use than the IaaS option. Also additionally, it is suitable for those who aren’t technically proficient.
IaaS: Here the client is given virtualized hardware resources, using which they can install the software environment they want before going onto building the web application they need. It is actually much better for businesses which handle complicated IT structures.
What are its Features and Benefits?
- Reliable: Hosting is done on a virtual partition, from an extensive array of underlying physical servers and not on just a single physical server. This ensures that if one of the servers ever have to go offline then there would be no problems or no effect on the availability as the virtual servers would continue pulling resources from the remaining cluster of servers.
- Speed: If you are running your website from a physical server then only the location of the site’s files can be accessed from that particular server location. So with a cloud server, your site can be visited from a variety of locations which can be closer to the actual physical location. This will result in an improvement in the site speed.
- Scalable: Here, the sky is the limit as the disk space and memory can be infinitely upgraded and can be done so from a variety of different servers because of no physical server limitations. So traffic spike which requires more space and other resources to balance out the load can easily be accessed.
- Price: You will only have to pay for what you use and so these extra cloud resources will be there whenever you need it, like when a traffic spike occurs. But you won’t have to end up paying for server resources which are not in use.
- Physical security: The underlying network of physical servers are housed within the data centers and so they benefit from the security measures taken by those facilities which involve preventing people from disrupting them, accessing them on site and more as such.
An example of a Cloud Hosting company
Surely anyone would still like to see an example of one such successful enterprise which is using cloud hosting – we would like to give you a famous one: Google. The crowned King of search engines has its resources spread all overloads of servers on the cloud. This also means that Google doesn’t face downtime or it hasn’t faced any in the past decade as such. Of course, it should be kept in mind, that Google has a lot of wealth at its disposal and so they can get many technological resources which small businesses might not be able to access.
Cloud hosting has come along way and as said in the example, a lot of large enterprises have been using it for years. But as can be determined, for small business owners, the pricing matters and to get them engaged more the pricing will have to decrease further. But it should also be said that the pricing has managed to get a lot lower and combined with all the advantages and practically non-existent disadvantages; this can be a good deal for mid-size organizations overall or for those small business owners who can take a leap of faith and invest in it.
Overall, one thing is clear- more and more businesses are making the shift to cloud and this trend can only be expected to continue.
