Multi-Cloud Enterprise Architecture Is The Key To Data Portability

Multi-cloud architecture allows a degree of cloud portability at the infrastructure and the DevOps level, interoperability and portability challenges still exist. Today, the cloud edge computing is now pushing computing applications, data, and services away from centralised cloud data centre architectures to the edges of the underlying network.

Enterprises are moving towards a distributed architecture with the multi-cloud environment and are pushing for integration of various devices. This is evident through the internet of things and network integration that cloud computing has moved away from centralised, large-scale data centres to a more distributed multi-cloud setting. This set-up is usually made up of a network of larger and smaller virtualised infrastructure runtime nodes. In the cloud as a virtualised architecture, virtual machines (VMs) are the core virtualisation mechanism. Virtualising enables the IoT infrastructures to be integrated. These architectures and their setting are known as edge clouds, edge computing or fog computing

Portability With Multi-Cloud Architecture

While multi-cloud architecture allows a degree of cloud portability at the infrastructure and the DevOps level, interoperability and portability challenges still exist. Today, the cloud edge computing is now pushing computing applications, data, and services away from centralised cloud data centre architectures to the edges of the underlying network.

While the core cloud provides a larger view, edge clouds lend localised views (to host services close to or at endpoints of networks), on-device, private cloud-like infrastructures.

A SearchCIO article defined interoperability in cloud computing as the means for public and private cloud services to understand APIs, configuration, data formats and forms of authentication and authorisation. The interfaces are standardised, “So that the customer can switch from one cloud service to another with minimal impact on the system as possible.”

We have also discussed in an earlier article how microservice architectures strive to break up monolithic single cloud architectures into small deployable services, supported by container architectures. Container services are loosely coupled and independent software components that can be rapidly called and mapped to any business process as required by engineers.

Microservices architecture is a new approach to build a single application like a collection of small services, with each application running in its own process and communicating with lightweight mechanisms. These applications can be deployed independently and are supported by a fully automated deployment and orchestration framework. These applications do not require synchronised deployments at fixed times.

Challenges In Multi-Cloud Environment

  1. The difference in performance metrics in original and the new cloud provider
  2. Differences in resources used by the original as opposed to a new cloud provider, for example, firewall issues, network addressing, identity services,
  3. Also, there will be differences in security policies and a lack of common cloud APIs

How To Reduce Challenges In Multi-Cloud Deployment:

Google: Mountain View tech giant Google tied up with VMware to offer cloud portability solutions which enable enterprise developers to deploy web applications across multiple environments and devices. The web giant also led the charge for data portability and kickstarted Data Liberation Front, dubbed as Google’s engineering team with the goal to allow users to move their data in and out of Google products via existing open standards.

RightScale: California-headquartered cloud management company RightScale used for streamlining operations across servers, cloud and containers provides a transparent platform designed to work across multiple clouds where users have the flexibility to choose the cloud vendor, to move data stores, and design the architecture and components using their own software library.

Cloud Foundry: Cloud Foundry is an open source platform which can help move data among PaaS systems, and container technology such as Docker can help move pieces of applications. This open source project gives users maximum flexibility to avoid vendor lock-in.

Outlook

Edge clouds have shifted the focus from heavy-weight data centre clouds to more lightweight virtualised resources, but this architecture is not without its own challenges. In this, lightweight virtualisation has emerged as a key challenge. Meanwhile, container technology can significantly advance PaaS technology towards a more distributed heterogeneous clouds by supporting interoperability.
