Difference between Business Hosting, Shared Hosting and VPS Hosting

Business Hosting: Business Hosting, as the name suggests, is basically a web hosting package on a server provided to online business and e-commerce of all aspects, as well as shared among other users who purchased business hosting. It also allows individuals and organizations to make their websites accessible online.

Shared Hosting: Shared Hosting, as the name suggests, is basically a type of web hosting that works by allowing users to share space on a single server that keeps costs low and easy to use web hosting service. The website generally resides on one web server that is connected to the internet.

VPS Hosting: VPS (Virtual Private Server) Hosting, as the name suggests, is basically a type of hosting that is widely used because it allows fewer users to share allocated segments of hard drive space, memory, etc., and offers virtual machines to clients. It provides reliability, security, and greater performance.

Difference between Cloud hosting and Dedicated Hosting

1. Cloud hosting :

Cloud hosting is one of the premium plan in the market for web hosting. Here the website is hosted on a set or a cluster of servers, many servers and machines are working synchronously as a single entity. Cloud hosting allows to create computing resources using cloud computing facilities. It offers good scalability and flexible in nature so that it easy to increase or decrease resources as per requirement. It is good for websites having high traffic. Its speed and flexibility makes its preferred choice for web hosting.

Pros of Cloud Hosting :

◉ On demand resource – pay on time.

◉ High availability – reliable.

◉ Better scalability – flexible.

◉ Recovering lost data.

Cons of Cloud Hosting :

◉ Advanced cloud knowledge is required.

◉ Platform dependency – cloud vendor collaboration

◉ Limited Control to users in use of services

2. Dedicated hosting :

In dedicated hosting a full server belongs to you means the website is stored on that single server which is dedicated only to that server. It is different than the shared hosting where in one server multiple websites are hosted. But here one physical server is dedicated to one site. The organization has the full rights on the resources of the server and it can be configured accordingly as per exact specification. So it gives higher performance higher level of security but it is more expensive as compared to other types of hosting.

Pros of Dedicated Hosting :

◉ Higher performance

◉ High level security

◉ Complete customization

◉ Best support when required

Cons of Dedicated Hosting :

◉ It is expensive than other hosting

◉ Requires skilled person for customization

Difference between Cloud hosting and Dedicated Hosting :

CLOUD HOSTING	DEDICATED HOSTING
In cloud hosting the website is hosted on a set or a cluster of servers, many servers and machines are working synchronously as a single entity.	In dedicated hosting a full server belongs to you means the website is stored on that single server which is dedicated only to that server.
Here cluster of servers provide service to the website.	Here a single server provides service to the website.
Cloud hosting gives good performance.	Dedicated hosting very good performance.
Cloud hosting is more scalable than dedicated hosting.	Dedicated hosting is not so scalable like cloud hosting.
Cloud hosting is less reliable than dedicated hosting.	Dedicated hosting is more reliable than cloud hosting.
In cloud hosting there is not a guaranteed uptime 24*7.	In dedicated hosting there is a guaranteed uptime 24*7.
Migration of cloud server on physical server is possible without any down time through hot swapping.	Here migration to other physical server either booting is essential where might be down time.
Cloud hosting charges as pay as you go model means pay as per your use.	Dedicated hosting does not charge as pay as you go model, it charges based on its fixed monthly plan, even when 100% of its resources are not used.
In cloud hosting securing a server is the vendors responsibility.	In dedicated hosting securing a dedicated server will be the clients responsibility.
Examples – Cloudways, A2 Hosting, Kamatera, Siteground, Hostinger etc.	Examples – LiquidWeb, InMotionHosting, HostGator, DreamHost, Bluehost etc.

2. Shared hosting :

Shared hosting is one of the most common plan in the market for web hosting as the hosting price is very less. Here one server hosts multiple websites. That’s why all websites share common resources like disk space, storage, and bandwidth. It is cost effective especially for websites with lesser traffic as hosting provider handles all technical tasks and also it is easy to use. But some time site loading time may be slow as it is shared also it is not suitable in case of heavy traffic.

Pros of Shared Hosting :

Pricing structure – It’s cheap.

Ease of use – Beginner friendly.

Well managed security, upgrades and maintenance.

No administrative responsibilities

Cons of Shared Hosting :

Slow load time as it is shared.

Security gets affected due to shared.

Lack of server control during overcrowd.

Does not offer good scalability

Domain Name System (DNS) Zones

Domain Name System (DNS) is divided into many multiple various zones. These zones distinguish between specifically managed areas within DNS namespace. 

Domain Name System (DNS) Zones is any distinct, connecting segment of domain name space in Domain Name System (DNS) for which administrative responsibility has been delegated to single administrative space which allows for more smooth control of DNS components. Namespace of web is organized into hierarchical layout of subdomains below DNS root domain. Individual domains of this tree may function as delegation points for administrative authority and management.

◉ DNS zones are hierarchical concept. Therefore, namespace is subdivided into areas (zones) for this purpose. The purpose of DNS zones is to permit easier control over multiple levels of website.

◉ As the number of resource records increases for single domain, it becomes complex to manage all of them. Network administrations moderate this issue by breaking down their configurations into multiple zones.

◉ Root name servers are responsible for root zone. Each TLD name server is responsible for zone covering its specific TLD, and authoritative name servers are responsible for some even smaller zones below that.

◉ The root and TLD name servers are actually just authoritative name servers, but, zones that they’re authoritative for are special cases.

◉ DNS zones aren’t necessarily physically separated from each other; zones are strictly used for delegating control.

Example –

Imagine large tech company named “Dreamwave” that owns domain “www.dreamwave” with further 2 TLD servers: www.dreamwave.com and www.dreamwave.org. This company has offices in Canada, India, and Japan. Let’s say each office has around 1000 people with their own uniquely named desktop computer. This would be 3000 “A records” for both .com, .org TLD, and to keep track of if it was all configured as single zone. What corporate could do, instead, is break up each office into their own zone.

So now, we could have ca.largecompany.com, in.largecompany.com, and jp.largecompany.com as subdomains, each with their own DNS zones. A total of four authoritative name servers would now be required for setup, one for dreamwave.com and one for each of subdomains, and similarly and total of four authoritative name servers for dreamwave.org.

Figure – zone hierarchy of “Dreamwave” along with DNS nameservers

Zone files :

Zones are configured through what is referred to as zone files, that contain an actual representation of zone, simple configuration files, that declare all resource records for specific zone. A zone file needs to contain an SOA or Start of Authority resource record declaration and Global Time to Live (TTL). This SOA record declares zone and therefore name of name server that’s authoritative for it. Global Time to Live (TTL), states for how records should be kept in local DNS cache. Along with SOA record and TTL, you’ll usually find NS records that indicate other name servers which will even be liable for this zone. The format of zone file is defined in RFC 1035 and 1034.

DNS zone file comprises of directives and resource records.

Directives begin with a $. There are three Directives:

◉ $TTL – Time to Live value for zone.

◉ $ORIGIN – Defines base name -used in domain name substitution

◉ $INCLUDE – Include a file

$TTL directive must be present at top of zone file before SOA record. While talking about zone files, it’s imperative to know about Reverse Lookup Zone.

Reverse Lookup Zone :

A reverse lookup zone contains mapping from an IP address to host (opposite function of most DNS zones). These zones are used for troubleshooting, spam filtering, and bot detection.

Just like how subdomains can go many layers deep, zones are often constructed to have many layers too, a bit like subdomains, although it’s rare to see certain zones deeper than just few levels.
