The demand for an appropriate server stems from the basic need to deliver high network performance. In line with meeting this primary requirement, the following details throw light on the difference between bare metal servers and virtual servers.
Bare Metal Servers
Also referred to as dedicated servers, this server deals with raw hardware. Also identified as a single-tenant physical server, such servers in line with their very name basically meet the tailor-made needs of a single user. These servers primarily come to use with data-intensive workloads that become the backbone for reliability and performance. There is a provision to include Graphic Processing Units (GPUs) which will work in tandem with the CPU of the bare metal server, thus leading to enhanced performance computing. The provision to opt for a private visualized environment is made possible along with the facility of a monthly billing plan as part of a budget-friendly customer-centric feature.
On the other hand, virtual servers can come as a perfect bet for enterprises eyeing on the characteristics of flexibility and scalability in their environment. Basically meant to build new applications on the cloud, these servers do their best in offering unknown computing needs.
The following are the two prominent scenarios which bring in the flexibility feature of virtual servers.
- A virtual server operating on a public node comes as the first scenario that brings in the concept of resource being distributed across multiple customers. It is a physical server that meets the demands of a multitenant environment.
- A virtual server which is running on a private node comes as the second option. This enables you to be the sole user of all the components of the physical server. Exclusively meant for your complete utilization, this is an option that will allow you to use up all the resources of the server. This can come with an hour-based or monthly billing plan as per the agreement.
Both these types of servers; bare metal servers and virtual servers can be created from scratch allowing users to create a template of their image to be stored in the SoftLayer library. Once saved, it makes it an easy job to load these on to your environment.
Here are the 2 types of images that can be captured and stored.
- Standard Images:
Such images are specific to virtual servers alone. Standard images can easily be captured from an operational virtual server irrespective of the operating system. Once captured, such an image can be used to create a new server.
- Flex Images:
Bare metal servers and virtual servers support flex images. However, it is important to note that flex images in contrast to standard images are compatible with a subset of operating systems.
Allowing users the ability to capture the image from a physical machine, such an image can then be used to create a new virtual server in line with the physical image.
Having enlisted the differences between these two types of servers, it comes as a wise move for organizations to give a deep thought about the components of their IT environment before zeroing on a particular option. This way, they will be taking a well-informed decision that is in line with the vision and mission statements of their organization.
Growth in business is the primary motivation for entrepreneurship. While companies begin to sense the signals of growth to their bottom line, the top management needs an answer to the query whether their operations call for an upgrade of their shared hosting server to the next level; a Virtual Private Server (VPS) also called as Virtual Dedicated Server. Seen as a via-media option between shared hosting and a dedicated server, the VPS not only ensures enhanced performance levels required for your business growth but also helps keep costs under check.
While it goes without saying that a huge budget needs to be allocated for hosting your website on a full server, VPS can be tagged as an affordable option. Keeping all these factors in mind, it is important for the management to consider certain aspects that should be addressed before going ahead with the technological decision to upgrade.
- A Closer Look At Your Resource Usage
Top management in tandem with your IT department heads should look clearly through the server usage logs to delve deep into the limits of usage set by your hosting provider. Specifications like server bandwidth along with CPU load and memory usage are of utmost importance favoring the viability of your business operations. It is important for you to keep a close watch on your limits and usage to ensure optimum utilization of resources. It is when you are touching the limits that the siren for an upgrade rings loud and clear.
- Money Matters
In contrast to managing your own servers, VPS offers the convenience and affordability of renting just the optimum amount of server computing needs that your business demands. This way, you are also paving way for the optimum utilization of your server while not getting bogged down by maintenance chores and the hole in your pocket created by a physical server.
- Performance Standards Met
While a VPS is your private server, there will be many other users that have signed up with your service provider. However, the good part of VPS is the performance of your server which is independent of the usage of other users sharing the same physical server. You have total control over your server parameters including CPU, memory, bandwidth and storage.
- Data Security
Having a designated space on the World Wide Web comes with certain cons. Data security is the prime concern of all the businesses treading the online path. This concern is well addressed by a VPS which secures your source files and data files in a designated fragment of your server, not accessible to other clients of your service provider.
- Flexibility to Scale Up or Down
Allowing businesses to add new VPS as and when the need arises is a star attraction with this upgrade option. On the flipside, the flexibility to scale down by removing those that are redundant brings to the fore the advantage of managing with a pre-set VPS overhead, along with a provision to cut down your VPS plan during business downtime.
Having enlisted all the pivotal considerations that should be kept in mind, a VPS comes across as a best alternative allowing your business to focus on what you deliver to your clients. However, after identifying the need for a VPS upgrade, the next step is to scout for a good provider who can bring in his expertise to your table, in line with your business objectives.
Why VPS Server Hosting Is Best For Your Blog
Shared Hosting allows your small business to use a portion of a robust server that is already being used by other bloggers and website owners. However, on the flipside, the increasing populace of website owners and bloggers signing up with shared hosting options will cramp up server space, negatively affecting your blog. Users might start experiencing sluggish website loading speeds and even increased downtimes.
Also, with time, you will start gaining more visibility; a consequence of gaining proficiency in writing as you continue to post blogs on a regular basis. Other bloggers will start following you, organic traffic would increase and a regular audience would start visiting your website. With all these developments comes a need to upgrade from Shared Hosting platforms to something better, such as the VPS.
Benefits of VPS Hosting
As a passionate blogger, moving on from Shared Hosting to a Virtual Private Server Hosting comes as an intelligent move for you to enjoy the following benefits.
- Topping the list of advantages is the privacy factor. VPS hosting offers you the luxury of greater confidentiality when compared to Shared Hosting. This will in turn help you to manage your blog in an efficient manner.
- Making you the proud owner of a unique IP address, this notable feature of VPS bestows a security cover to your blog. Allowing you to exercise better control over your content, you will certainly be “buying peace of mind” by opting for VPS. With the power of having administrative permissions in your hands, this paid server option smoothens many rough edges.
- The facility of customization comes in as another noted advantage of VPS hosting, allowing you to modify the server to suit your needs. You will have the freedom to install various software applications. Permitting upgrades to take place, you can also alter server configurations; all in accordance with your changing needs and preferences.
- Compatibility with different operating systems like Windows, Linux and OSX makes VPS the top pick for small to medium enterprises to manage their blog content through control panels like Plesk and cPanel.
Changing with time is the surest path to progress! Having said this, paid VPS hosting comes as a boon to enterprise blogging. It helps you to reap the benefits of enhanced traffic without worrying about the server experiencing issues such as downtime due to components such as CPU, disk space, RAM and bandwidth. Hence, it will not be an exaggeration to quote that a small investment towards VPS goes a long way in bestowing multiple benefits to your company blog.
Reasons for Enterprises to Use Virtual Private Servers
Virtual Private Servers (VPSs) exist between the expensive dedicated and cheaper shared hosting server options. It is ideal for a wide variety of web hosting situations.
4 important reasons to make Virtual Private Servers your choice is as follows:
Are you getting complaints from your users regarding slow response time of your website? Does your website show any improvement in traffic? If not, then you should go for a better level of hosting. Virtual Private Server is similar to shared hosting. One or more than one virtual server can be hosted on a single physical server, resulting in a lower price. One common problem with shared hosting is that one hosted website can hog the resources which the other servers on the host also need. But with virtual private servers, such an issue does not arise.
In shared hosting, a lot of websites run from a single operating system. Because of this, if any of these sites face a server issue, it would also affect other websites which are hosted on that particular server. But in virtualization, multiple virtual servers can run on the physical host and every virtual server will be having its own operating system and services. In this situation, if any of the virtual server crashes, it will not affect other websites hosted on that server. Similarly, if any of the virtual servers hangs/freezes due to any problem with the database or similar issues, you can restart it safely without affecting others.
Websites which are running on the shared hosting platform are running on the same operating and file system. It is clear that one shared hosting client can affect the files of other clients on the same server. But in VPS, if one file crashes, other will not get affected as it has exclusive operating system and services. Virtual Private Servers are fully independent from other virtual servers running on the same host except for physical presence.
If you are running your site on a shared hosting environment, then the hosting firm will have some restrictions on what can be provided and what cannot in order to guarantee the quality of server to other clients on the same server. For example- your hosting company will not allow you to reboot the server according to your needs as it may take down the website of all other clients hosted on that server. Similarly, there are several types of custom configuration useful for your sites, but it can’t be allowed as it may affect other clients. If your web app or website needs more control on the server environment, then you must go for a Virtual Private Server as it would be the perfect option for you. And moreover, you can get “root” access to your VPS at cheaper rates as compared to a dedicated server.
Virtual Private Server Hosting bridges the division between dedicated servers and shared hosting and gives you all the benefits of a dedicated server at the price of shared hosting.
Virtual Private Servers (VPS) – What Can You Use It For?
If you are a business owner looking for a cost-effective, scalable and flexible web hosting solution, a Virtual Private Server is your best choice. So, what is it and does it fit your requirements? Let’s see.
What is a Virtual Private Server (VPS)?
As the name suggests, Virtual Private Servers are a virtual space for hosting your website. The virtual space is created by partitioning physical server space using software. Each VPS has the ability to run its own OS. Thus, it essentially offers the benefits of a dedicated server while being more user-friendly.
Being partitioned with software, your server resources are not shared. Therefore, VPS is ideal for your fast growing.
What are the major purposes you should use a Virtual Private server for?
You can opt for Virtual Private Servers for three major purposes.
1) Website Management
This is the most obvious purpose for choosing a VPS hosting solution. It offers you dedicated server space with a lot of flexibility and scalability. For growing businesses, these two aspects are vital to ensure good user experience.
You are guaranteed of dedicated resources such as processing power, disk space and RAM. There might be instances when you outgrow your original dedicated server space.
You can take the example of Prisma. The developer behind the app hardly expected it to become astounding success it became. So he opted for a dedicated server with limited space. But, when the app became an overnight success, he had to run around to increase his server capacity. The app experience was seriously slow for a number of users.
Now, you might not have the same scenario. But, at a time when competition is high, the impression your software or website creates on the user can make all the difference.
2) For Creating a Test Environment
If you have website or software ready for launch and needs to be tested, the virtual private servers can be used to create a test environment. As VPS allows you to install different software, you can test with different software, OS and other variables.
With VPS you can easily set-up fresh environments and run them quickly. It saves you from wasting time to adjust your existing set up for testing.
3) For SEO Benefit
VPS can allow faster connections and page load speed. They ensure that users have a far better experience while on the website. Due to this, your SEO rankings can go higher. A faster loading website can directly influence a number of key SEO factors such as average session duration, bounce rate, etc
As VPS servers are set up within high security data centres, there would be minimal power interruptions. Website crashing would be minimal as well. The data centres are usually backed 24/7 by technical support and service.
Top 5 Reasons to Use a Virtual Private Server
Virtual Private Servers (VPS) have improved over time in both functionality and performance. Unlike dedicated servers, VPS hosting offers you lots of customization options and flexibility to restructure and manage resources.
From an economic point of view, VPS offers you a good choice, costing less than a dedicated server while being slightly higher priced than shared hosting.
There are numerous reasons for you to choose a VPS hosting solution over both dedicated server and shared hosting. Here are the top 5:
Cost: A few years ago, VPS hosting services was very costly due to technological limitations. But now, as virtualization technology advances, prices have come down, and they would continue to lower.
Due to lower expense, you can consider VPS hosting despite your website size. Some available options are as low as that of shared servers. Being Virtual Private Servers, you don’t have to put up with performance issues and risks usually associated with shared servers as well.
Security and Segregation: As each virtual server is independent of other servers, activities on other servers do not affect your server.
In the case of shared hosting, your server might be hosted along with someone who has an experimental website. And if he brings down the server, you’ll be affected as well.
Also, there would be occasions when some software packages are not supported by your shared hosting service provider. This could be due to your provider’s policy due to security concerns. There are no such issues with VPS hosting.
Scalable: For fast growing businesses, scalability can be a hurdle in the case of dedicated server. If you have to increase the RAM of your server for instance, it would have to be added physically.
But in the case of VPS, you can add RAM with the click of a button. This is because your server is hosted in something known as a container, which offers the flexibility to add or remove resources. Thus, you can scale easily and quickly, ensuring minimum traffic loss.
Better Performance: Compared to shared hosting, in which your server performance gets affected due to other websites hosted in the same server; VPS provides you far better performance. You are allocated fixed amount of RAM, memory and CPU, which ensures more stable and reliable performance.
Efficient, Environment-friendly Technology: By using VPS, you are actually lesser carbon footprint than when you are using dedicated servers. In the case of dedicated servers, you are the exclusive beneficiary of the server. But, in VPS hosting, numerous people share the benefits of a huge dedicated server. This way, the carbon footprint left is relatively smaller.

cPanel is a leader in simplifying hosting environments with intuitive yet powerful dashboards. The cPanel/WHM 11.50 lives up to expectations by adding several new features and improvements to its lauded list of features and offerings.
Here are the 10 new features that you must absolutely know and leverage:
1. Support for CentOS7
Support for fresh installations of CentOS 7 (both 7.0 and 7.1) has been introduced in the latest release. This support introduces the powerful (and recently updated) features of the operating system. The latest upgrades of CentOS7 introduce support for two-factor authentication, a major IPA update, improved support for container, and addition of the OpenJDK8 for developers, and returning the Thunderbird.
Furthermore, you can install the cPanel & WHM with MariaDB instead of MySQL. Learn how with the Installation Guide.
2. Greylisting’s Spam Magic
Protect your server against spam with the new Greylisting feature that defers all emails sent by unknown and new triplets using the new cpgreylist daemon. WHM’s Greylisting feature is accessible through Home>Email>Greylisting, where you can:
· Configure Greylisting’s interface for each of your hosted domains. Accesible via Home>Mail>Configure Greylisting
· Add trusted hosts to a safe list
· Monitor activity through reports.
3. Calendars and Contacts
Two new protocols, the CardDAV and CalDAV allow Webmail and cPanel account users the ability to remotely create and share their calendar and contacts using third party applications. The protocols can be accessed through on two secure ports (2079 and 2080). The interface can be configured at:
· cPanel users: Home>Mail>Calendars and Contacts Client Configuration
· Webmail users: Home>Mail>Webmail
However, the CalDAV feature will not work with iOS Reminder apps if the server is using a self-signed SSL certificate.
4. A New cPanel User System IDs
The range for possible number of User IDs (UUDs) and Group IDs (GIDs) has been changed. Now servers running CentOS7 can create between 200 to 999 UIDs and GIDs. Other supported OS can create a maximum of 500.
5. Corrupt MySQL System Databases Notifications for Administrators
A new script that runs with nightly maintenance has been introduced for monitoring the MySQL system databases. All essential databases are regularly checked, and in case of a corrupt database, the server administrator will be sent an email — continuously at spaced time periods till the database is no longer corrupt.
6. A Simpler Way to Remove Plugin Files
The uninstall_plugin script (/usr/local/cpanel/scripts/uninstall_plugin) introduces a simpler way for removing all the files of a plugin. Further information is available at 11.5’s Uninstall Plugins documentation.
7. Quickly identify trigger visitors with Passive OS Fingerprinting
The GeoIP identifier has been improved and email notifications will offer additional information (including OS). Newer, customizable templates for notifications are available in the Template Toolkit. The additional information allows enhanced visitor segmentation as you can quickly identify visitors that trigger events.
8. Dedicated Horde SQLite Database
The Horde data that was previously stored on MySQL has been move to cPanel’s very own Horde SQLite database. This is valid for only the cPanel & WHM version 11.50. If you decide to migrate to an earlier version, the account’s Horde data will not be exported to the MySQL database for Horde. You will have to perform the migration manually. For any problems with Horde migration, read cPanel’s documentation on Horde Data Behavior
9. Increased Default Password Strength and PostgreSQL Account Suspension
With the 11.50, the strength for the default password has been raised to 40, whereas the PostgreSQL accounts that were previously not been suspended during the suspension process has been corrected.
10. cPHulk stores Login History for an Year
The cphulkd.known_netblock MySQL table store netblock information and username for all successful login. A useful notification for users/admins accessing the server via dynamically assigned IP addresses.
A Virtual Private Server (VPS) is an independent server within a server. When a VPS is created, one physical server (master server) is made to host multiple virtual servers. This is done with software (namely, hypervisor) that segments the master server’s hardware specs so that each VPS segment functions separately and independently of one another.
Segmenting a server basically means that each VPS runs its own operating system — one that is independent of the main server, and which can be rebooted at will without affecting any other VPS. It’s primary advantage is in offering hosting at cost-effective rates and with greater freedom of configuring and organizing online servers.
How does a Virtual Private Server (VPS) work?
The functionality of a VPS can be described using four terms: compartmentalization, dedicated resources, root access, and isolated hosting environment.
To create a VPS, the physical server is divided into multiple virtual compartments (virtual CPU specs, RAM, hard disk space, etc). Think of it like segmenting a hard disk into multiple drives. However, with a VPS, compartmentalization goes beyond just allocating hard disk space.
When the server software is set up, each virtual compartment is allotted a specific quota for using the master server’s resources. This includes a dedicated percentage of the server disk space, CPU, and RAM. Hence, when your website is hosted in this new compartment it will operate as if the allocated resources make up the specs for its server. This obviously means that the more compartmentalization’s that exist on a master server, the more powerful hardware it deploys.
When compartmentalization and resource allocation are complete, the VPS behaves like a standalone, dedicated server. Hence, you will gain complete root access to the server (and hence complete control over server), allowing you to configure the VPS system as per your needs. As a result, every single server is allowed to select its very individual operating system, configure existing components, and setup new ones and be able to restart it at anytime.
Compartmentalization creates an isolated environment for your VPS. Whatever changes you make, or configurations you perform on your VPS cannot affect any other VPS on the same system. The same holds true for all other VPS on the master server. Hence, any instances of malware or cyber threats that have affected, or are affecting any VPS on the master server cannot affect your VPS.
Think of it like living in a colony of bunkers, where though each may be sharing the same resource pool, each is self sustaining and completely isolated from neighboring bunkers. Hence, with a VPS, even though all the VPS servers on the master server are sharing the same hardware resources, each will always operate differently from each other. If one server has a problem, it’s there problem alone and none of the other servers will be affected because of it.
SSD (Solid State Drive) VPS
SSD VPS options like the ones available here for Europe provide super fast and reliable hosting solutions paired with 1Gbps or 10Gbps bandwidth ports.
