Hybrid Cloud Challenges that Needs Attention

FREMONT, CA: Deploying hybrid clouds are a real challenge for the CIOs. Besides taking advantage of the elasticity of public cloud, the CIOs need to create an application model that addresses the data center, and security, and compliance rules. Cloud computing provides agility, i.e., replaces the broken components or scale overloaded ones. When incorporated into hybrid cloud architectures, cloud front-ends are less resilient than expected, according to the CIOs. The back-end data centers of the hybrid cloud architectures do not respond to the problems with the same agility, which cloud is known for.

Cloud providers and third-party vendors have added Kubernetes services and other containers to tackle hybrid cloud challenges. Still, the disconnection between public cloud models and on-premises remains the key obstacle for CIOs today. The Kubernetes and containerized application deployments work for a wide range of scenarios, from microservices-based cloud applications to legacy monolithic applications.

Programming requires a language and a set of APIs to provide applications with access to hardware, software, and network resources. For this reason, PaaS is being redefined for hybrid and multi-cloud. It is essential to know the new PaaS model for the hybrid cloud users as they will have to optimize the evolving set of add-ons to build a unified model of their own. The revamped PaaS model lacks middleware consistency, which is its most immediate disadvantage. A standardized way should be discovered to bind containers into workflows and monitor conditions to enable the applications to scale under pressure or load.

Considering the cloud infrastructure as a series of Kubernetes 'domains' is the best way to synchronize cloud-based assets and on-premise. Kubernetes clusters are aligned to the hybrid cloud relationships, rather than to data center locations. A set of defined boundary domains must be set to scale across multiple clouds because the components get scaled up and redeploy themselves in a cloud or data center. This controls the resources to be used at the boundary between the private and the public clouds, which in turn handle aspects like host scaling and resilience.
