What Is Dedicated Servers And Its Management?
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 operating systems or applications.
Management
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
Application updates
Server monitoring
SNMP hardware monitoring
Application monitoring
Application management
Technical support
Firewall services
Anti-spam software
Antivirus updates
Security audits
DDoS protection and mitigation
Intrusion detection
Backups and restoration
Disaster recovery
DNS hosting service
Load balancing
Database administration
Performance tuning
Software installation and configuration
User management
Programming consultation
Dedicated 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.
Managed – Includes medium level of management, monitoring, updates, and a limited amount of support. Customers may perform specific tasks.
Self-managed – Includes regular monitoring and some maintenance. Customers provide most operations and tasks on dedicated server.
Unmanaged – Little to no involvement from service provider. Customers provide all maintenance, upgrades, patches, and security.
