Using the CyrusOne IX for Active-Active, Active-Passive and Active-DR Interconnection A better use of time and money is to use large Web-scale carrier-neutral data centers containing the resiliency required for power, cooling, seismic stability, and most importantly, connectivity.

Establishing the Right DR Strategy Most enterprises today are required to operate at least a simple disaster recovery (DR) data center strategy to maintain business continuity due to regulations and other factors Single consolidated including uptime resiliency. Compliance, regulations and due diligence often necessitate data center the active synching of IT environments to each other (active-active) or asymmetrical • With all of the eggs in one basket, synching to each other (active-passive). harden the basket. These enhanced DR strategies require highly connected data centers within specific latency parameters, and also require careful site selection. Factors for site selection include power-grid resiliency (there are three grids in North America: East, West and Electric Reliability Council of Texas (ERCOT)), seismic mitigation and network availability. These three factors can create a daunting task for an enterprise, especially when needing to hire dedicated staff to select, build and operate these facilities.

Two data centers Using in-place optical waves, multiprotocol label switching (MPLS) and Internet Protocol • Active – passive (IP) transit greatly reduces costs and removes the need for expensive telecom hardware • Active – active and the staff to operate that hardware.

How a National IX Works The CyrusOne National Internet Exchange (IX) meets many requirements for connectivity by delivering carrier-class infrastructure to data centers. This neutral platform has dedicated high-speed multiple carrier waves and MPLS between sites already in place. All of this can be delivered from simple cross-connects or a dynamic IX Ethernet switch port.

Three or more data centers A simple analogy is that an IX is like a large international airport. Many airlines arrive at an airport, but they may not own all the air routes departing from that airport. • Active – active – passive Therefore, they may rely on other airlines to carry their passengers or cargo to their • Active – active – active final destination. Passing through a large airport provides a passenger with multiple connections and facilitates a competitive environment between airlines to try to capture that business.

An IX is, simply stated, the airport of the Internet. It is located in strategic geographic locations where multitudes of fiber-optic cables are located, typically with large, dense populations of users nearby.

2 CyrusOne Enterprise Data Centers | 855-564-3198 | CyrusOne.com Most IX are Not Cost-Effective Solutions for Enterprises Currently, IX are located in “carrier hotels” where space is very limited and pricing has become untenable for anyone other than the largest Internet service providers (ISPs) and content companies. If an enterprise locates its information technology (IT)infrastructure within one of these IXs today, pricing can be very high for the required data center space and power.

This high pricing creates a dilemma. Enterprise companies want the value and resiliency of connecting to the IX, however, enterprises typically have large core production environments, so the cost of locating that much hardware in a carrier hotel is not economically feasible.

Another Connectivity Option is Now Available There is, however, a dramatic movement being driven by large Internet companies that is changing this dynamic. These companies operate gigantic compute farms with millions of servers located in very large wholesale or company-owned data centers. As content has moved away from carrier hotels, it has pulled the core of the Internet traffic away with it.

As multiples of these content companies cohabitate within geographic areas (mostly due to lower power costs), they are creating new edge interconnection points. Adding IX at these edge sites now creates a viable connection point for a large-scale enterprise as well. Additionally, there is movement into metro and nationally connected IXs in North America.

3 CyrusOne Enterprise Data Centers | 855-564-3198 | CyrusOne.com This movement is enabling the edge IX to be directly interconnected to the carrier hotel IX, thereby creating an ecosystem of peers, partners and providers to the edge- connected companies. This immediate ecosystem of connectivity drives resiliency up for the Internet and costs down for the edge-collocated enterprise.

If an enterprise uses the IX to exchange data with cloud providers, the connection into that cloud provider would be direct without any intermediary ISP or carrier. This direct connection gives an enterprise control over their traffic and lowers the cost basis for access to the compute power they need with the cloud provider. It also enables an enterprise to connect to multiple cloud providers across a single port on the exchange using Border Gateway Protocol (BGP) or 801.11q VLAN tagging. A simple interface with multiple partners is as dynamic as it gets for an enterprise.

Purchasing Internet transit, MPLS or dedicated optical waves is a process fraught with high costs for an enterprise. The high cost is due to carriers serving enterprise data centers in remote locations, office buildings or other non-core locations. To account for this added edge infrastructure, the carriers must charge more to recover their investments.

To solve this issue, an enterprise should locate its infrastructure within a large carrier- neutral data center, providing access to the infrastructure of the carriers that does not require the cost recovery of an edge location.

The CyrusOne National IX Delivers Robust, National Connectivity Enterprises locating large-scale production environments within Web-scale carrier- neutral data centers can benefit from connectivity cost savings and enjoy a more reliable data center operated by teams focused on uptime.

The cost savings advantage of accessing the CyrusOne National IX within the site and multisite environments is a simple formula for dynamic interconnection of the modern enterprise.
