The colocation provider supplies the physical space and infrastructure required to keep the equipment operational.<\/p>\n<p>A colocation facility may provide:<\/p>\n<ul>\n<li>rack or cabinet space;<\/li>\n<li>power and backup systems;<\/li>\n<li>cooling;<\/li>\n<li>physical security;<\/li>\n<li>network connectivity;<\/li>\n<li>facility monitoring;<\/li>\n<li>on-site technical assistance.<\/li>\n<\/ul>\n<p>This allows organizations to maintain control over their hardware without having to build and operate their own data center.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>Colocation allows businesses to host their own hardware in a third-party data center.<\/li>\n<li>The customer typically retains ownership and control of the equipment.<\/li>\n<li>The data center provides space, power, cooling, security, and connectivity.<\/li>\n<li>Colocation provides professional data center infrastructure without requiring a company to operate its own facility.<\/li>\n<li>Colocation differs from dedicated server hosting because the customer typically supplies the physical hardware.<\/li>\n<\/ul>\n<h2>How Does Colocation Work?<\/h2>\n<p>The customer installs or delivers physical equipment to a data center, where it is placed in an allocated rack, cabinet, or other designated space.<\/p>\n<p>The facility then provides the infrastructure required to operate the equipment.<\/p>\n<p>A typical colocation deployment involves:<\/p>\n<ol>\n<li><strong>Hardware deployment<\/strong> \u2014 The customer installs servers, storage, networking equipment, or other hardware.<\/li>\n<li><strong>Rack space<\/strong> \u2014 Equipment is placed in a rack, cabinet, or allocated facility space.<\/li>\n<li><strong>Power and cooling<\/strong> \u2014 The facility provides electrical and environmental infrastructure for the equipment.<\/li>\n<li><strong>Network connectivity<\/strong> \u2014 The equipment is connected to the internet, carriers, private networks, or other available services.<\/li>\n<li><strong>Physical security<\/strong> \u2014 Access to the facility and equipment is controlled through the data center&#8217;s security procedures.<\/li>\n<\/ol>\n<p>The customer is generally responsible for managing the hardware and software, although additional managed or remote-hands services may be available depending on the provider.<\/p>\n<h2>What Is Included in Colocation?<\/h2>\n<p>The exact services depend on the facility and service agreement, but colocation generally covers the physical infrastructure surrounding the customer&#8217;s equipment.<\/p>\n<h3>Rack Space<\/h3>\n<p>The customer receives space for servers and networking equipment, usually measured in rack units (U) or provided as a dedicated cabinet or rack.<\/p>\n<h3>Power<\/h3>\n<p>The facility provides power for customer equipment and may include redundant power feeds, UPS systems, and backup generators depending on the deployment.<\/p>\n<h3>Cooling<\/h3>\n<p>Data centers use dedicated cooling systems to maintain suitable operating conditions for servers and other equipment.<\/p>\n<h3>Physical Security<\/h3>\n<p>Professional data centers typically use controlled access, surveillance, monitoring, and other measures to protect customer equipment.<\/p>\n<h3>Network Connectivity<\/h3>\n<p>Colocation facilities can provide access to internet carriers, network providers, internet exchanges, and other connectivity services.<\/p>\n<p>XLC operates infrastructure from Tier 3+ data centers in Los Angeles, Tokyo, and Hong Kong. Its network infrastructure includes multi-carrier connectivity, Tier 1 IP transit, and internet exchange peering.<\/p>\n<h2>Colocation vs Dedicated Server Hosting<\/h2>\n<p>Colocation and dedicated server hosting both provide access to physical computing infrastructure, but the hardware ownership model is different.<\/p>\n<p>With colocation, the customer typically supplies and owns the physical hardware. The provider supplies the facility and supporting infrastructure.<\/p>\n<p>With dedicated server hosting, the provider supplies the physical server and rents access to it to the customer.<\/p>\n<table class=\"glossary-term-table\">\n<thead>\n<tr>\n<th>Characteristic<\/th>\n<th>Colocation<\/th>\n<th>Dedicated Server Hosting<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Hardware

that need control over custom physical equipment may choose <a href=\"https:\/\/xlc.com\/jp\/dedicated-servers\/\">dedicated servers<\/a>, while businesses looking for ready-to-deploy infrastructure may choose dedicated server hosting.<\/p>\n<h2>Colocation vs On-Premises Infrastructure<\/h2>\n<p>Both colocation and on-premises infrastructure allow organizations to own and control their physical equipment.<\/p>\n<p>The main difference is where the equipment is hosted.<\/p>\n<p>With on-premises infrastructure, the business operates the servers in its own facility and is responsible for the supporting environment, including power, cooling, physical security, and network infrastructure.<\/p>\n<p>With colocation, the hardware is deployed in a professional data center that already provides these facility-level services.<\/p>\n<p>This allows organizations to maintain control over their infrastructure without having to build and operate an entire data center themselves.<\/p>\n<h2>Benefits of Colocation<\/h2>\n<h3>Hardware Control<\/h3>\n<p>Businesses can select their own servers, storage systems, networking equipment, and other hardware according to their technical requirements.<\/p>\n<h3>Professional Data Center Infrastructure<\/h3>\n<p>Colocation provides access to purpose-built facilities with dedicated power, cooling, physical security, and network infrastructure.<\/p>\n<h3>Connectivity Options<\/h3>\n<p>A data center may provide access to multiple carriers and network providers, giving customers more options for connecting their infrastructure.<\/p>\n<h3>Data Center Location<\/h3>\n<p>Businesses can place physical infrastructure closer to users, partners, cloud environments, or target markets.<\/p>\n<p>XLC provides infrastructure from data centers in Los Angeles, Tokyo, and Hong Kong, supporting organizations with global and Asia-focused infrastructure requirements.<\/p>\n<h3>Custom Hardware<\/h3>\n<p>Colocation can be useful when a business needs specialized hardware that is not available as a standard server configuration.<\/p>\n<h2>Common Colocation Use Cases<\/h2>\n<h3>Enterprise Infrastructure<\/h3>\n<p>Businesses can deploy custom servers and networking equipment in a professional data center while retaining control over their infrastructure.<\/p>\n<h3>Private Cloud<\/h3>\n<p>Organizations building private cloud environments can use colocation to host the physical servers supporting those environments.<\/p>\n<h3>Hybrid Infrastructure<\/h3>\n<p>Colocated hardware can operate alongside public cloud resources, allowing businesses to combine physical infrastructure with cloud services.<\/p>\n<p>XLC supports hybrid architectures by connecting its bare metal infrastructure with cloud environments through dedicated private links.<\/p>\n<h3>High-Performance Workloads<\/h3>\n<p>Specialized infrastructure for databases, analytics, AI, storage, and other demanding workloads can be deployed in a data center environment with professional power, cooling, and network infrastructure.<\/p>\n<h3>Disaster Recovery<\/h3>\n<p>Businesses can use geographically separate facilities to host backup infrastructure and maintain access to critical systems if the primary environment becomes unavailable.<\/p>\n<h2>Colocation and Network Connectivity<\/h2>\n<p>Network connectivity is an important consideration when choosing a colocation facility.<\/p>\n<p>Depending on the facility, customers may have access to multiple carriers, internet exchanges, cloud providers, and private connectivity options.<\/p>\n<p>This can be particularly important for organizations serving users across multiple regions or connecting physical infrastructure with cloud environments.<\/p>\n<p>XLC&#8217;s <a href=\"https:\/\/xlc.com\/jp\/network\/\">global network<\/a> combines multi-carrier connectivity, Tier 1 transit, internet exchange peering, and connectivity options for distributed infrastructure.<\/p>\n<h2>What Should You Consider When Choosing Colocation?<\/h2>\n<p>Several factors can affect whether a colocation facility is suitable for a particular deployment.<\/p>\n<h3>Power and Redundancy<\/h3>\n<p>Check available power capacity, redundancy, backup systems, and whether the facility can support the requirements of your hardware.<\/p>\n<h3>Cooling Capacity<\/h3>\n<p>High-density servers and specialized equipment can have significant cooling requirements, so the facility&#8217;s cooling infrastructure should match the planned deployment.<\/p>\n<h3>Network Connectivity<\/h3>\n<p>Consider available carriers, network providers, internet exchanges, bandwidth options, and connectivity to the regions your users need to reach.<\/p>\n<h3>Physical Security<\/h3>\n<p>Review access controls, surveillance, on-site security, and other measures used to protect the facility and customer equipment.<\/p>\n<h3>Location<\/h3>\n<p>The location of the facility can affect network latency, accessibility, regulatory requirements, and proximity to users or other infrastructure.<\/p>\n<h3>Remote Hands and Support<\/h3>\n<p>If your team cannot regularly access the facility, check whether the provider offers on-site assistance for tasks such as equipment installation, troubleshooting, or hardware replacement.<\/p>\n","protected":false},"featured_media":0,"template":"","glossary_category":[193],"class_list":["post-6598","glossary","type-glossary","status-publish","hentry","glossary_category-data-centers"],"acf":[],"yoast_head":"<!--
