Web Hosting Services OptionsWeb Hosting Services Options

Options:– Self-hosting– Co-location– Managed Hosting– Shared Hosting

Architecture OptionsArchitecture Options

Self-hosting: Establish web server in our own office, on our own network.– Pros: Complete control – immediate

response to agency needs and changes, managed alongside our internal systems.

– Cons: Complete responsibility – hardware procurement and maintenance, environmental control, physical and network security, drain on bandwidth and other resources, etc.

Architecture OptionsArchitecture Options

Co-location: Provide agency-owned server in an outside vendor’s datacenter.– Pros: Nearly complete control – agency owns

and operates hardware and software; vendor provides space, environmental control, physical security, network bandwidth.

– Cons: Nearly complete responsibility – little or no vendor monitoring or support; response time increased due to physical distance from server; same procurement and maintenance requirements as self-hosting.

Architecture OptionsArchitecture Options

Managed Hosting: Vendor supplies and maintains hardware and basic software at the vendor’s datacenter.– Pros: Flexibility of control – vendor monitors

hardware, software and security 24/7; provides bandwidth, environmental controls, backup units; outsourcing expertise available on demand.

– Cons: Greater monthly cost, reliance on vendor’s SLA (service level agreement).

Architecture OptionsArchitecture Options

Shared Hosting: Vendor provides space on server, shared among several different “tenants.”– Pros: Lower cost, vendor provides all basic

server requirements.– Cons: Little control of anything, limited

technical capabilities; competition for hardware, software, bandwidth and other resources; 3rd party applications for other customers may reduce our uptime; our growth must also accommodate others on same web server.
