As cloud based architectures became more and more popular over the past decade, different organizations are facing different challenges when evaluating the possibility to leverage the managed services offered by various providers. While these services can make operations and maintenance easier and more cost effective, there are certain cases that require careful planning and precise execution. One such case is the question of data residency and the related regulations and security concerns, hot topics for financial and government institutions, as well as multinational corporations.

Strict limitations regarding the location of data do not necessarily mean it's impossible to integrate cloud services to the current infrastructure. Different solutions labeled as hybrid cloud are set to resolve this issue, all similar in approach but with different tradeoffs. In general, the aim is fulfill security and compliance imposed regulatory requirements by keeping part of the data on-premises, and either via custom solutions or by using existing services designed for this purpose, connect these local data centers to the cloud network. Often this means the database engine and the servers powering the systems will be running on the cloud provider, which in turn means some of the data still has to travel outside of the local network.

In case it's absolutely necessary to keep all data on-premises, one possible solution is the recently released AWS Outposts service. AWS Outposts offers the same AWS hardware infrastructure, services, APIs, and tools to build and run applications on premises and in the cloud for a truly consistent hybrid experience. AWS compute, storage, database, and other services run locally on Outposts, and development teams can access the full range of AWS services available in the Region to build, manage, and scale on-premises applications using familiar AWS services and tools.
