Enterprise SaaS Workloads on New-Generation Infrastructure-as-Code (IaC) on Multi-Cloud Platforms

Abstract

Cloud Computing has become the primary model used by DevOps practitioners and researchers to provision infrastructure in minimal time. But recently, the traditional method of using a single cloud provider has fallen out of favor due to several limitations regarding performance, compliance rules, geographical reach, and vendor lock-in. To address these issues, industry and academia are implementing multiple clouds (i.e., multi-cloud). However, managing the infrastructure provisioning of enterprise SaaS applications faces several challenges, such as configuration drift and the heterogeneity of cloud providers. This has seen Infrastructure-as-Code (IaC) technologies being used to automate the deployment of SaaS applications. IaC facilitates the rapid deployment of new versions of application infrastructures without degrading quality or stability. Therefore, this work presents a vision of uniformly managing the infrastructure provisioning of enterprise SaaS applications that utilize multiple cloud providers. Hence, we introduce an initial design for the IaC-based Multi-Cloud Deployment pattern and discuss how it addresses the relative challenges.

Uses of Languages in Cloud Computing in Context with its Security

“…In the context of cloud computing, the systems to be protected can be heterogeneous [8]. Therefore, a security policy aimed at protecting all systems involved should be as independent of the system as possible, which implies that the language must also be independent of the system [9,10]. For this reason, the proposed language is based on the notion of contexts associated with the resources to be protected.…”

Adaptive Neuro-Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN) for Predicting the Kinematic Viscosity

“…In the BP phase, the difference between network output values obtained in feed forwarding and desired output value is compared with previously determined difference tolerance and the error in output layer is calculated. This error value is propagated backward to update the links in the input layer [53].…”

Cloud Data Security Methods: Kubernetes vs Docker Swarm

“…A cloud host can be available anytime, and if it isn't, there should be a warning period before the services restart. [9] Integrity: A cloud vendor or service must offer this essential quality. On truth, the term "data integrity" applies to the consistency and correctness of any database, even those stored in the cloud.…”
