All about Managed hosting


Managed Hosting bridges the gap between the ease-of-use of standard webhosting services to co-location. Managed Hosting is essentially a service where you have complete administrative abilities over a system provided by your internet service provider, but they set it up, provide the computer to your specifications, and keep it up to date.
Web hosts have been offering dedicated servers for a while now, however, because dedicated servers can be difficult to operate technically, there has been a demand for web hosts to provide extra services such as: reporting and monitoring; managed load balancing; managed security; managed storage; and, managed databases. These extra services are referred to as ‘managed hosting’.
Managed hosting is ideal for the new online businesses person, looking to build a large online business, and wanting to avoid the extra time and resources spent in-house on managing their dedicated servers. In-turn, managed web hosting has provided a profitable outcome to many online businesses by preventing a waste of valuable resources spent on high skilled employees; months of staff training; and, costs of hardware and software.

What should I look for in a managed hosting provider?

When choosing a managed hosting provider it is a good idea that your host provides the following qualities:

Reliable and fast support a good way to find out the response rate and the quality of the services offered by a web host is to send them an email before you sign up with them. If you receive a good response from your web host then this should give you a good indication of the services they are offering.

Freedom its important to have as much freedom as possible and having the ability to choose from a wide range of services is essential. With managed hosting you might decide that you don’t require firewall support, its important that your web host will provide you with the option of selecting exactly what you need and what you don’t need. Also having the ability to pay monthly is a huge advantage. It will be less of a drain on your budget and you can avoid any expensive yearly contracts.

Fast and reliable connection You should find out exactly what sort of connection the web host has to the Internet. By asking the web host they should be able to send you their network and connectivity details, you might even be able to find this out on their web site. Also find out where the web hosts Network Operations Center (NOC) is located, it is an advantage for the web host to have its NOC located in the USA as the USA has the fastest and most reliable internet connection in the world.

Competitiveness When searching for a managed hosting provider it is important to do your research. Each web host will be offering different managed hosting services all at different rates, you might find that one web host may offer one attractive managed hosting service while another doesn’t. However, as many more web hosts are beginning to offer managed hosting, a new competitive market is developing and the prices for managed hosting are becoming much more affordable with many more services being offered.

Dedicated Hosting
The Common Gateway Interface (CGI) is a standard for interfacing external applications with information servers, such as HTTP or Web servers
A HTML document is not executed in real-time.Therefore it is static,Whereas cgi program is executed in real-time,therefore it is dynamic.
CGI program transmits user information to the server and receive the results back again and display them to the client.

Clustered Dedicated Servers a healthy approach


Clustered Dedicated Servers share the processing power with many servers in real time. Theses servers overcome the limitations of one physical server. This is also known as Grid web hosting technology. The advantage of these servers is that if one server has some threat then the other servers are available to share the load. Every server cluster which is setup for clients is customized to their requirements. Basically cluster is an arrangement of normal servers; if user rent more than two servers then they will configure a private VLAN to provide secure gigabit communication between the servers.

There are some top best clustered dedicated server providers:-

Core benefits:

Some benefits are there for clustered dedicated server:-

  1. Redundancy and Reliability: Different configurations in cluster server can give the user active or passive features in case of failure of one server. Passive feature involves running applications having redundant dedicated servers. Active configuration involves two-server sets run applications or services and takes data from common database in case of system failure.
  2. Load Balancing: To configure the server for maximum speed and performance when there is a lot of traffic might requires splitting traffic and functions among servers. Clustering allows anyone to improve services, operations and detect cyber attacks before downtime.
  3. High availability: Clustering reduces system failure and vulnerability. Implementation of databases, web servers, dual load balancers prevent downtime, cyber attacks and natural disasters.

Types of server clusters:

There are three different types of server clusters:-

  1. Single Quorum device cluster: It is also called the standard quorum cluster. There are multiple nodes with one or more which are also called cluster storage and it has also a connection device which is called bus.
  2. Majority node set cluster: In this type of cluster, each node maintains its own copy of the cluster configuration data. The resource keeps configuration data which is compatible across the nodes.
  3. Local Quorum Cluster: It is also called single node cluster which has single node and is used for testing.

The node configuration can be categorized into following models:

  1. Active/Passive: This configuration requires most extra hardware. It provides a fully redundant instance of every node.
  2. N+1: This refers to clusters that have multiple services running simultaneously. It provides a single extra node which is brought online to take over the role of failure node.
  3. N+M: It is used in cases where a single cluster is managing many services having one dedicated failover node.
  4. N-to-1: It allows the failover standby node to become the active one temporarily, until and unless original node can be restored.
  5. N-to-N: N to N clusters redistribute the services, instances or connections from the failure node among the active nodes and eliminate the need for ‘standby’ node.

Node Reliability:

The techniques which make shared infrastructure as reliable:

  1. Disk mirroring: It prevents internal disk failure to avoid system crashes. For example: Distributed Replicated Block Device.
  2. Redundant network connections: It prevents network outages from interface failures, single cable and switch or network.
  3. Redundant electrical power: It inputs to different circuits protected by uninterruptible power supply units which prevents from loss of power to the system.

Fail-over Strategies:

Systems that handle failures have different strategies to cure:

  1. Fail Fast: It is the attempt to cure failures if the first node cannot be reached.
  2. On Fail, Try One-Next Available: It means the system tries one host which is most accessible or available.
  3. On Fail, Try All: It means the system tries all existing, available nodes.

Managed hosting A great option


For managing a very high traffic website you will definitely tuned for Dedicated server as it is suitable for handling heavy load on your website.But as far as management is concerned many companies go for ‘Managed Hosting‘.

Its natural that this question may arise in our minds that’What is the difference between Dedicated Hosting and Managed Hosting’?

A dedicated hosting solution you are given your own private server and have complete control over its use. That is why dedicated servers are capable of handling too many visitors of a website.However you are responsible to manage that server yourself. Some of the issues you will deal with include selection of hardware and operating systems, choosing applications, dealing with security issues, backing up your data, monitoring for up-time and lots more.

Managed hosting is a gateway for dedicated hosting. You not only have your own dedicated server, but the Managed Host provides all or part of the management, maintenance, and monitoring needs for you.

Cost of Managed Hosting:

To be frank, managed hosting costs much then other hosting.But this cost can be amortized through high quality maintenance.When compared to the cost of having full-time IT staffing in-house managed hosting becomes very cost effective. One benefit is that the outsourcing can be scaled to your particular needs. The managed host can provide a little or a lot depending on your growth and traffic.

It is the time for the next step for your site!


Dedicated servers are used because shared web hosting services has its some limitation. Those people needs dedicated server who is having large number of visitors on their sites and want to have full control on every aspect of their servers and also need to store a lot of information in large databases.

Dedicated server hosting is that type of website hosting where the clients doesn’t share the server with anyone else. This hosting is more reliable and flexible than the shard hosting because you have the full control over the server. The hosting company can usually provide administration or management of the server.

Cpwebhosting provides best and reliable dedicated server with multiple quality uplinks. The prices of these dedicated servers of cpwebhosting are very reasonable and affordable to all. Cpwebhosting is having improved routes to their location also.

Cpwebhosting provides administrative maintenance of the operating system for their clients. It includes upgrades, security patches and updates, adding or deleting users and domains and special programming requirement.

When you need dedicated server?
If you have a large mailing database then you will run into restrictions on sending mail from a shared server, a dedicated server may be a suitable option. Those who contemplating a large network of multiple sites, dedicated server is the best option.

Controlling a high server load


In the era of highly complex system configuration, it is not peculiar to get high server load spikes. Relying over better server optimization and load mitigation approaches can make the work half. There are three general steps taken for high server load troubleshooting in Linux server:-

  1. Look out for resource which is overloaded: Here we search for the resource which is getting hogged. Atop is an ideal tool if we are troubleshooting the physical server or you may use regular top command if we are over OS virtualization environment. If VPS node is loaded, you might start with VZtop.
  2. Look for the service which is hogging that resource: Once we get identified of the resources then we can use specialized tools to look for services which are making that resource hogged.
  3. Look for the virtual host who is using that service: Once we get acquainted of the specific service then what is needed is to accomplish specific service activities.

While optimizing getting known of the services which are not causing resource to hog is equally important to services which are causing it. Having a habit of frequently checking all command outputs in a normal server will give you the power to immediately see what is wrong.

There has been steep growth in data traffic owing to the proliferation of connected device, which has increased the demand on data center for webhosting service providers. Industry prefers standard Intel architecture for techno solutions and data center consistency as it is scaling up network infrastructure. Intel has released its first XEON processor with SOC (system on chip) technology on its 14nm process technology which accomplishes I/O capabilities over same chip. The new processor is delivering up to 3 to 4 time’s faster performance per node comparing to Intel® Atom™ processor C2750, part of its 2-gen 64-bit System on chip products family. Initially Intel will have two XEON D processor Xeon D-1520 and Xeon D-1540 which is targeted at data center including dedicated hosting and storages. Initial products are optimized for hosting providers for variety of loads.

Enhancing Uptime with VMware HA and DRS rules:

VMware Ha and DRS can improve server performance and uptime working together if correct configuration and planning is implemented. VMware’s HA (High Availability) and DRS (Distributed Resource Scheduler) are two of the software company’s virtualization management. VMotion is used to scale the server across multiple hosts and HA restarts the virtual machine in case of host failure. ESX/ESXi version has already had these features but they are not exclusive to each other so they have to work in unison. DRS does not concern about number of virtual machine per host, consequently not making adjustment on virtual machine count.

There are two categories for setting up DRS and HA according to the classification of the virtual machine that we want to separate and don’t want to separate.

  • Separating VMs seems easy and may seem to protect against failure but as business environment grows, keeping VMs separate becomes more complex. It cannot be considered much secure as if network issues occurs then still we might have trouble. The separation of VMs with required hardware in blade server environment might come beneficial .A rack outage may be catastrophic to virtual environment owing to the higher density of virtual machines per rack with blades. In blade system we must limit the numbers of blade enclosure in single rack which may prove better for HRS and DA protocols.
  • We may want to keep some VM on same host.E.g. A front end server and database server communicate frequently so it is preferable keep them on same host. By residing them on same VLAN will keep network traffic internal to host and decreases the excessive physical network traffic .Here the problem arises if they both go down. If they both are interdependent to each other then it is less meaningful to put one to start without other one and also they should start in correct order .We can overcome start up order problem by putting VM in Vapp. Here a lot of stress is over priority start up of VMs, having VMs that do not start automatically is lucrative option.HA allows VMs to violate constraint of resources. This does mean if the cluster is not having sufficient resources, it needs to start up then it will not get started. By not starting development and test VMs does help with additional resources while overriding the resource constraints may make it start. Here clusters might be running slower but it is beneficial then not running system at all.

Making safe action with documentation:

We don’t have the simple way to extract rules or rules with HA and DRS configuration. The only way is to completely disable DRS and HA. Unlike other tools there is no undo button. Keeping notes of rules for HA start-up priority, resource pool setting and VM sepeiration may be the safe action to perform

VPS and reseller hosting server


Virtual Allocated Server or Virtual Private Server enables you to lease VPSs, running on the same server independently from each other, but sharing its network, hardware, operating system, etc.to your first-hand and reseller end users.
Virtual servers have their own root accounts and root directories in sub-directories of the main server. VPSs are completely isolated from each other and from their main physical server. Virtual Private Servers allow to limit physical server resources, such as traffic, disk space, RAM, the number of running processes and files in use.

With Reseller Allocated Servers, You can assign physical servers to resellers, so that you can create end user’s homes on it, with the help of Allocated Servers. Every reseller signing up for the plan obtains one of available physical servers. In case there are no allocated servers available for the plan, reseller signing up with it, will be moderated and you will be notified of it through trouble ticket system.
