A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone else. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware,
etc. There is also another level of dedicated or managed hosting
commonly referred to as complex managed hosting. Complex Managed Hosting
applies to both physical dedicated servers, Hybrid server
and virtual servers, with many companies choosing a hybrid (combination
of physical and virtual) hosting solution. There are many similarities
between standard and complex managed hosting but the key difference is
the level of administrative and engineering support that the customer
pays for – owing to both the increased size and complexity of the
infrastructure deployment. The provider steps in to take over most of
the management, including security, memory, storage and IT support. The
service is primarily proactive in nature.
Server administration can usually be provided by the hosting company as
an add-on service. In some cases a dedicated server can offer less
overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC
systems. In contrast to colocation, the server hardware is owned by the
provider and in some cases they will provide support for your operating
system or applications.
A hybrid cloud solution provides the ultimate in
control and flexibility. Combine the best characteristics of public
cloud computing, virtualization and private dedicated infrastructure to
build the most cost effective infrastructure for your business critical
services, with the flexibility to scale your services in response to
changing demand and workloads.
Using a dedicated hosting service ( dedicated managed hosting ) offers the benefits of high
performance, security, email stability, and control. Due to the
relatively high price of dedicated hosting, it is mostly used by
websites that receive a large volume of traffic.
Dedicated hosting services primarily differ from managed hosting
services in that managed hosting services usually offer more support and
other services. As such, managed hosting is targeted towards clients
with less technical knowledge, whereas dedicated hosting services, or
unmanaged hosting services, are suitable for web development and system
administrator professionals.
To date, no industry standards have been set to clearly define the
management role of dedicated server providers. What this means is that
each provider will use industry standard terms, but each provider will
define them differently. For some dedicated server providers, fully
managed is defined as having a web based control panel while other
providers define it as having dedicated system engineers readily
available to handle all server and network related functions of the
dedicated server provider.
Server management can include some or all of the following:
- Operating system updates
- Server monitoring
- SNMP hardware monitoring
- Application updates
- Application management
- Technical support
- DDoS protection and mitigation
- Anti-spam software
- Antivirus updates
- Firewall services
- Security audits
- Application monitoring
- Intrusion detection
- Backups and restoration
- Disaster recovery
- DNS hosting service
- User management
- Load balancing
- Database administration
- Performance tuning
- Software installation and configuration
- Programming consultation
Dedicated managed hosting server providers define their level of management
based on the services they provide. In comparison, fully managed could
equal self managed from provider to provider.
Administrative maintenance of the operating system, often including upgrades, security patches, and sometimes even daemon
updates are included. Differing levels of management may include adding
users, domains, daemon configuration, or even custom programming.
Dedicated server hosting providers may provide the following types of server managed support:
- Fully managed – Includes monitoring, software updates, reboots, security patches and operating system upgrades. Customers are completely hands-off.
- Self-managed – Includes regular monitoring and some maintenance. Customers provide most operations and tasks on dedicated server.
- Managed – Includes medium level of management, monitoring, updates, and a limited amount of support. Customers may perform specific tasks.
- Unmanaged – Little to no involvement from service provider. Customers provide all maintenance, upgrades, patches, and security.
