6. Colocation vs Cloud Computing: Understanding the Differences

In colocation, you acquire and retain ownership of the hardware (servers) and software necessary for hosting your web presence, along with the responsibility for their setup and configuration. Additionally, depending on your requirements, you may opt to purchase network devices such as switches, routers, firewalls, or VPN appliances to control inbound and outbound traffic to your servers.

Typically, providers do not sell these devices to you, nor do they impose restrictions on your purchasing choices; you have the freedom to select the combination that aligns most effectively with your requirements.

Upon completion of preparation, you proceed to install your equipment at the data center of the chosen colocation provider. While they may offer assistance with this process, typically it falls under your responsibility. The provider furnishes you with space within a data cabinet at their facility, supplies power to your equipment, assigns IP addresses for your use (or facilitates a cross-connect to a dedicated carrier if you bring your own bandwidth), and allocates an uplink port for connecting your equipment to their network, thereby enabling access to the Internet.

Premium facilities maintain 24/7 staffing and offer basic support upon request, yet you are accountable for maintaining your equipment and are granted physical access as needed. The colocation provider assumes responsibility for ensuring the security and maintenance of the facility, safeguarding the space, power, and bandwidth they provide to prevent any compromise.

Cloud services involve the provider provisioning and overseeing hardware infrastructure, encompassing servers, storage, and network components. This arrangement eradicates capital expenditures (CAPEX) and reduces operational expenditures (OPEX), as the provider’s personnel, rather than the customer’s IT staff, handle daily administration, regular maintenance, troubleshooting, and issue resolution.

Conversely, in colocation, customers are still required to procure their own servers, storage, switches, and software. Additionally, the time of IT staff will still be allocated to monitoring and managing the equipment, as well as conducting backups and maintenance.

Nevertheless, numerous colocation providers now present managed services that can be utilized for infrastructure monitoring and management. It is advisable to select a provider offering a diverse range of options, allowing customers to choose which functions they prefer to be managed by a third party while retaining control over them.

The choice between colocation and cloud computing is not necessarily an exclusive one. Companies can feasibly opt for different solutions to fulfill various tasks.

Example, an organization might choose to run the majority of its daily processing systems on a public cloud server, while opting to host its mission-critical databases on its own server. Deploying this server on-site would pose both expense and security concerns, leading the company to seek a colocation facility capable of housing and maintaining its most vital equipment.

Consequently, the decision between colocation and cloud hosting services becomes one that executives and IT professionals must evaluate on a per-asset basis within the corporate framework. Simply migrating all assets to either a colocation facility or a cloud service provider could result in missed opportunities to implement synergistic solutions.
