What Is DCI? A Simple Guide to Data Center Interconnection

A growing company does not stay inside one building for long. Over time, it opens new offices in new places. Along the way, it gains more customers each year. As a result, it also saves more data each year. Eventually, the company ends up using more than one data center. Because of this, these data centers need a strong link. That link lets them work as one system. This is where DCI, or data center interconnection, comes in. DCI is a group of links and tools. Together, these links connect separate data centers. Once connected, the data centers share data safely. In turn, a company can move data between places fast, even when those places sit far apart. Meanwhile, more businesses move their work online. As they do, they save more and more data. Because of this, the need for a strong link between sites keeps growing. The part below explains this need. What is DCI? DCI stands for data center interconnection, which means the links that join two or more data centers. Through these links, the data centers share data smoothly. Fiber cables, switches, and other tools build these links. Together, the tools move large amounts of data from one place to another. Today, most companies run their systems across more than one site. They use multiple sites for backup, speed, and storage. As a result, a company can no longer skip this kind of link. Skipping it slows things down, loses data, and makes systems fall out of sync. Grand View Research found the world market for this technology was worth USD 10.12 billion in 2024. By 2030, the market will reach USD 20.37 billion. In other words, it grows at a rate of 13.1 percent each year. What are the main types of DCI? There are a few common types of DCI. Businesses pick a type based on their needs and budget. Some types focus on speed. Others, however, focus on low cost or more flexibility. The list below shows the main types. Building a stronger connection between your data centers DCI plays a big part in keeping modern businesses connected.
