Why You Should Opt For a Virtual Data Center (VDC) Instead of a Virtual Server
What is Virtual Data Center.A Virtual Data center (VDC) is a pool of cloud resources (virtual CPUs, RAM, HDD, networks) that enables you replace the need to operate your own datacenter. In other terms, one of the benefits of virtual data center is that you don’t have to buy and house your servers.Instead of housing the servers, you have access to virtual servers which allows you access to all business applications you need.Virtual servers affords flexibility and scalability as needed. In simpler terms, you have as many virtual servers you need without having to buy, house, or provision a physical machine. In this environment,you can create virtual machines, containers (vApps), networks. You can increase its capacity when needed by adding new resources (CPUs, RAM, drives, IP-addresses) A vDC contains public and private catalogues of VM templates so you can build new virtual machines quickly, or upload VMs that are already running in your other environments. Central to the vDC are vApp’s
A virtual server on the other hand is a separate virtual machine with an operating system that was preinstalled. Virtual servers however are not connected to each other through local network.The operating system for virtual server also depends on a lot of factors.Although, virtual server has its benefits, benefits of virtual data center far outweighs that of a virtual server.
Going for Virtual Data Center instead of virtual server has lots of advantages. Benefits of virtual data center include;
Timely provision of IT resources for a company growing rapidly
A start up company or a developing company cannot predict in advance the resources that will be required but there’s no need to worry because with VDC, there are more resource compared to virtual server.
Most times, it turns out that demand significantly exceeds the cautious expectations of business owners. The existing IT infrastructure is unable to take on more load, instead of a costly and resource intensive upgrade, VDC can always be used from the inception.
Virtual data center can be cost effective in the long run. Instead of constantly upgrading your virtual server plans, there are enough resources on VDC that can be used for a long time.

Wonder how CDN network works. ?Content delivery network refers to a group of servers that are geographically distributed to provide fast delivery of internet content. They are the backbone of the Internet in terms of content delivery. Whether you are aware or not, every one of us interacts with CDNs on a daily basis; whether you shop online, own an ecommerce store, watching videos, reading articles or going through posts on social media.
No matter what you do, or what type of content you consume, chances are that you’ll find CDNs behind every character of text, every image pixel and every movie frame that gets delivered to your PC and mobile browser. CDN services continue to grow in popularity and most web traffic is served through CDNs
To really understand how CDN network works, you first need to understand the issue they are designed to solve. This is known as latency. It’s that delay you experience when you load the url of a page to that time you see the contents on your screen.
The delay experienced is caused by a number of factors, some caused by specific websites but in all cases, the delay is caused by the physical distance between where you website hosting a server is located and where you are. Therefore, how CDN network works is to shorten that physical distance thus making websites load faster with better performance.
CDN BEHIND THE SCENES
When you load that website URL , the web browser requests for a resource, the first action is to make a DNS request. Making a DNS request is similar to looking for a phone number in a phone book. The browser offers a domain name and expects an IP address in return. With the IP address, the browser then contacts the web server directly for subsequent requests.
How does CDN improve website load times?
When it comes to website speed, users drop off quickly as the site slows down. CDN can help reduce load times in the following ways;
• The globally distributed nature of a CDN means reduce distance between users and website resources. Instead of having to connect to wherever a website’s origin server may live, a CDN lets users connect to a geographically closer data centre. Less travel time means faster service.
• Hardware and software optimizations such as efficient load balancing and solid-state hard drives can help data reach the user faster.
• CDNs can reduce the amount of data that’s transferred by reducing file sizes using tactics such as minification and file compression. Smaller file sizes mean quicker load times.
CDNs are very useful for a different reason. For website owners who have visitors in multiple geographic locations, content will be delivered faster to these users as there is less distance to travel. CDN users also benefit from the ability to easily scale up and down much more easily due to traffic spikes.

Choosing An Operating System For Your VPS
Now that you have decided to go for a virtual private server, finding how to choose an operating system for VPS is the next important stage. This will form the core of the server configuring your virtual private server, one of the most important decisions you’ll make involves deciding the best OS for VPS as the operating system will form the core of your server, determining which apps you can install. When trying to pick the best OS for VPS, you must be very attentive as the different hosting options can easily confuse even the most tech savvy website owners. Sometimes, plenty of businesses online don’t know what they actually need. As a result, a great number of websites can’t handle the high loads and provide their visitors and owners with poor performance, regular downtime and low functionality. To prevent this, I decided to outline some features and benefits of VPS which is of one of the major hosting solutions.
There are basically two types of OS- Linux operating system and windows operating system.
Linux-based hosting solutions use the Linux open-source software. Due to this fact, website owners can reduce cost since there’s no need of purchasing licenses for downloading and running particular Linux programs and add-ons. For companies looking to make a fast start, but still have budget limitations.
Advantages of Linux VPS Servers
It is important to note that there’s a difference between shared hosting and VPS. In finding how to choose an operating system for VPS,here are some advantages of Linux OS for VPS,
• Flexible and reliable — Linux VPS servers use less resources, which increases website performance and excludes the appearance of possible downtimes Also, users can allot resources between applications if required with the help of a control panel called cPanel.
• Compatible — if you are concerned about making your website pages more user-friendly and improving your server reliability and uptimes, then the Linux platform will be the most preferable choice, as it supports a wide range of coding languages, such as PHP, Python, Perl, MySQL and Ruby on Rails;
• Interaction — all VPS servers are equipped with SSH text-based command systems. This allow users to improve the functionality of their servers and reduce their overloading dramatically. Although, a user must possess particular coding and programming knowledge to implement his operations via an SSH system;
• Development — as the Linux platform is open source, a website owner can change his server configurations, perform update, as well as install various add-ons and applications, basing only on his needs and preferences.
Windows VPS Hosting
If you are popular with PCs, then you probably know Windows OS or windows hosting. Windows VPS servers work under the Windows operating system, which makes them very popular among a lot of website owners. It is important to note that these hosting solutions are more expensive, as the Windows platforms are commercial software, which requires fees for installing and using additional programs and applications.
Advantages of Windows VPS Servers
Using a windows OS for your virtual private server gives you the following advantages;
• Improved control — every user is provided with an option called Remote Desktop access. Using this, a user can control and manage his server anywhere and at any time.
• Website support — Windows-based hosting solutions include such programs as ASP and ASP.NET, which will come in handy, if you want to create complex websites or customize your current website that runs on the Microsoft software;
• Strong security — as a rule, Windows VPS servers are furnished with professional antivirus software and anti-spy program and also reliable firewalls, so you shouldn’t be worried that your server will be hacked and your data stolen.
The points above shows what to consider when thinking of how to choose an operating system for VPS. Differences between these hosting solutions are apparent. It is worth mentioning that when you choose between Linux and Windows VPS servers, you must first consider your business needs and goals and pick whichever one suits your business needs.

What is the Difference Between a Virtual Server and a Dedicated Server?
In a nutshell, one of the major differences between dedicated server and virtual server is that resources of a virtual server are split between different websites or hosting account while a dedicated server is literally dedicated to your own personal use. You have rights to all of the resources of the machine, and you can configure the hosting environment anyway you wish.
Dedicated servers are most often the fastest and most powerful choices available, although some of the high-end VPS options can give the lower performing dedicated servers a run for their money.
Looking at differences between VPS and dedicated server,one of the major attractions of a dedicated server is that it is generally completely under the control of the customer. Therefore, it can be rebooted when needed and can also be completely customized in terms of the software it runs. Customized software can be very important for a number of reasons, but even if the software is off-the-shelf, not all VPS and shared web providers give their customers carte blanche to install and run additional software.
Virtual private servers has its benefits, although, they are a little harder to get one’s head around than dedicated servers, mainly because dedicated servers are something that nearly everyone can identify with: a computer. Virtual private servers are different from dedicated servers in that instead of running one hosting account on one computer/server, virtual private servers share a single server.
This may cause one to wonder what the difference is between a VPS solution and a shared web host. This is a fair enough question, and there may be variations to the answer depending on who one chooses to ask.
The most basic answer is that shared web hosting plans are mostly offering unlimited bandwidth and often unlimited storage, but there is no promise in regards to the amount of CPU power and/or memory available in most cases. Additionally, there are often restrictions on installing and running CPU/memory intensive modules or software, as hosts may view such software as very disruptive to the other accounts on their server(s).
Considering the differences between dedicated server and virtual server,finding the right balance between price and performance is always a challenge, but remember that you usually get what they pay for. Sadly, sometimes people get less than they pay for too, so be careful when assuming that money alone is a good measure of quality and capacity. Compatibility is also important, and thus sticking with top-tier hosts with established names is probably a good idea for those with serious hosting needs.
