To keep up with the disruptive and competitive changes happening today, organizations are quickly accelerating to use cloud computing services. Moving to the cloud often means access to infinite computing resources and a higher level of enterprise security.
It is critical for companies to migrate to the cloud to take advantage of scalability and agility. However, such migration is not as easy as it sounds.
Three difficult issues that many companies face are:
Virtual Private Networks or VPN gateways have never been a method for secure application access. Traditionally, network perimeters or Demilitarized Zones (DMZ) offer several network security layers using a portfolio of networking appliances. This adds to the extra costs of migration.
In the cloud, the idea of a network is a rather abstract concept. Services are often routed to ensure traffic gets to a specific destination. Implementing SDN in the cloud may seem like a great idea, but most engineers will have to climb the SDN learning curve to make it happen.
Since every cloud is an independent network, that means access to each one must be built individually. Authenticating users to resources in the cloud must be accomplished in an efficient and effective manner.
It might be easy to imagine building a network security perimeter in the cloud, but always easier to be said than done. If you want to know more about the best ways to move a traditional network security perimeter to the cloud, click the link below for more information.
