Windows Failover Clustering (WFC) is one of the oldest technologies utilized by Windows Server for the high availability of systems and services, whether that be traditional on-premise IT infrastructures or hybrid and multi cloud infrastructures in Microsoft Azure. Failover clustering and other relevant Microsoft technologies such as Always On Availability Groups are in many cases the cornerstone of a resilient and solid infrastructure design. In various real life scenarios however, administrators come across incidents and issues in their Windows failover clustering infrastructure which have a significant impact on business operations and may incur catastrophic downtime for services offered to customers.

Security and privacy is a frequent topic of discussion nowadays. With ever increasing IT infrastructures at the service provider and enterprise level as well as with increasing IT knowledge among the average knowledge workers and home users, being aware of security and privacy fundamentals is of paramount importance for ensuring smooth operations of IT systems involved at all levels.

When deploying an on-premises virtualization infrastructure (which could also be thought of as a private cloud with the sole customer being the enterprise/organization itself) various services and server roles should be considered in order to achieve a complete virtualization solution.

It is a common theme in various Cloud migration projects to migrate a number of on-premise apps to a public or hybrid cloud infrastructure. Depending on the application development framework and the dependencies which the application has to run efficiently (e.g. runtime frameworks, database and file storage requirements, user identity management and so forth), a custom choice is made each time regarding how to migrate an application to the Cloud. This article provides a quick overview of viable options for application cloud migration.
