Azure Arc: a new approach to hybrid environments

The use of hybrid architectures in enterprise reality is more and more predominant, they allow you to continue to benefit from investments made in your on-premises environment and, at the same time, use the innovation introduced by the cloud. The adoption of hybrid solutions is a winner if it takes into account a shared policy for distribution, component management and security. Without consistency in the management of different environments, the costs and complexities are likely to grow exponentially. Microsoft has decided to respond to this need with the solution Azure Arc, involving a range of technologies with the aim of developing new hybrid scenarios, where Azure management services and principles are extended to any infrastructure. This article presents the approach adopted by Azure Arc for hybrid environments.

The complexity of IT environments is constantly expanding to the point where we find reality with applications based on different technologies, active on heterogeneous infrastructures and maybe that adopt solutions in different public cloud. The need for customers is to be able to adopt a solution that centrally allows them to inventory, organize and enforce control policies on their IT resources wherever they are.

The principle behind Azure Arc is to extend Azure management and governance practices to different environments and to adopt typically cloud solutions, how DevOps techniques (infrastructure as code), even for on-premises environments.

To achieve this, Microsoft has decided to extend the model Azure Resource Manager so that we can also support hybrid environments, this makes it easier to implement the security features in Azure on all infrastructure components.

Azure Arc consists of a set of different technologies and components that allows you to:

  • Manage applications in Kubernetes environments: it provides the ability to deploy and configure Kubernetes applications in a consistent manner across all environments, adopting modern DevOps techniques.
  • Allow Azure data services to run on any infrastructure: everything is based on the adoption of kubernetes and allows achieving more easily meet compliance criteria, to improve the security of data and to have considerable flexibility in deployment time. At the time the services covered are Azure SQL Database and Azure Database for PostgreSQL.
  • Organize, manage and govern all server systems: Azure Arc extends Azure governance and management capabilities to physical machines and virtual systems in different environments. This solution is specifically called Azure Arc for servers.

Azure Arc involves the use of specific Resource Provider for Azure Resource Manager and the installation of Azure Arc agents is required.

By logging in to the portal, you can see that Azure Arc for Servers is already currently available in public preview, while you need to register to manage Kubernetes environments and data services in preview.

Thanks to the adoption of Azure Arc which introduces an overall view, you can reach, for hybrid architectures, the following objectives, difficult to achieve otherwise:

  • Standardization of operations
  • Organization of resources
  • Security
  • Cost Control
  • Business Continuity
  • Regulatory and corporate compliance

Conclusions

Azure Arc was recently announced and although still in an embryonic phase, I think that will evolve significantly enough to revolutionize the management and development of hybrid environments. To keep up to date on how this solution will develop you can register at this page.
