New Cloud-Based Data Architectures
As you adopt cloud platforms, data movement becomes more critical than ever. This is because clouds are not a monolithic, permanent destination. Odds are also that your organization has no plans to abandon on-premises datacenters wholesale anytime soon. Hybrid cloud architectures will remain the rule. In addition, as organizations’ knowledge and requirements evolve, IT will need to move workloads frequently between clouds and even back on-premises.
Change Data Capture (CDC) makes the necessary cloud data transfer more efficient and cost-effective. You can continuously synchronize on-premises and cloud data repositories without repeated, disruptive batch jobs. When implemented correctly, CDC consumes less bandwidth than batch loads, helping organizations reduce the need for expensive transmission lines. Transmitting updates over a wide area network (WAN) does raise new performance, reliability, and security requirements. Typical methods to address these requirements include multipathing, intermediate data staging, and encryption of data in flight.
