As cloud use cases and the public cloud matures, hybrid cloud and multi-cloud adoption is growing significantly. Hybrid cloud is the preferred enterprise strategy, according to RightScale’s 2017 State of the Cloud Report. The trend clearly shows that more and more vendors are looking to deploy less critical workloads in the cloud and run critical database (or even apps) on premise data centers. The concept behind this trend is known as edge computing (sometimes also called fog computing) where most of the local and critical processing is done on the edge instead of sending all the data to the cloud. The trend of edge computing and the hybrid cloud is clearly identified by public cloud providers such as Azure and the on premise Azure stack — both evidence of a growing trend.
Almost all of the Enterprise using the cloud believes in a multi cloud approach; making sure that they are not locked in with just one cloud vendor and have either on premise or have multiple cloud vendors. So, hybrid cloud comes with two options:
- On premise + public cloud combination
- Public cloud 1 + public cloud 2 combination
In both cases, networking for the hybrid cloud is key.
