Scope: A household-name financial services organisation was looking to commission a new data centre for their operations in the Asia Pacific region, into which a large amount of regional IT assets could be consolidated. This DC needed to provide a number of services, both internally and externally facing, and also needed to act as a hub-site for all APAC remote workers to access the corporate network.
Equipment Used: A VSS pair of Cisco 4500-X switches, Palo Alto firewalls, Cisco ASA security appliances for VPN, Meraki MX100s for the in-region SD-WAN capability, NetScaler MPX appliances for CAG access. In addition, an Opengear CM7100 series console server was also deployed behind a Cisco 2900-series router for out-of-band management access.
Delivery: As only a single facility in the region was requested, the design needed to be as resilient as possible. In addition, due to the speed at which the Asia operation was growing and changing, the design needed to be as flexible as possible, to allow new capabilities to be brought rapidly online.
Audience: Primarily business users, with some consultation with other SMEs within the organisation.
Challenges: The APAC operation was running under strict budget control at the time that this design was commissioned, so all decisions had to be carefully balanced against budget impact. This included several discussions about the requirement for resilience in all aspects of the design, and ultimately reduced resiliency in some areas, however the risks were captured and assessed accordingly and discussed with the project sponsor for acceptance and sign-off by senior stakeholders.
Takeaways: Pressure from the business sponsor around budget control was judged to have been more important than a fully resilient deployment. Ultimtely, the design met the requirements of the brief, and the customer was happy to accept the risks and sign off on the proposal.
