Introduction
Intercloud Fabric provides access to end-users and IT admins for life cycle management of physical, virtual, and cloud workloads. A typical inter-cloud fabric provider is a virtual appliance that can be deployed and managed by cloud providers. Multi Virtual Machine platforms, application development platforms, network virtualization, shared storage are the evolving IAAS and PASS services. Application development platforms need to include application life cycle management tools. The cloud is becoming popular for deployment. Enterprises are moving away from in-house and on-premises hosting of apps.
Cloud Deployment
Development teams can use them to maintain code, project information, and application tests. Environments can be used to promote applications from development to staging, acceptance, and then to production. Platforms can be configured to have network traffic channeled into multiple paths. This improves security and scalability. PAAS providers should have the capability to provide the platform, complex ordering, configuration. PAAS providers should not be a group of unrelated IAAS style virtual machines.

Enterprises are identifying and embracing the mix of public, private cloud, and on-premise IT. This new trend is expected to go up in next coming years. CXOs are balancing their initiatives in the enterprise to embrace a hybrid cloud. This is helping in creating IT governance over business data and delivering compliance to the enterprise. The new requirement for the cloud is to provide multiple private line carriers to get enterprise data into the facility in a secure and compliant way.
Cloud Security
Security concerns initially created obstacles for embracing the cloud as the deployment infrastructure. The important concern is IT infrastructure being in the hands of a third party. Enterprise needs to evaluate the cloud provider for data loss risk and data breaches. Software-defined security is part of the software-defined data center. Software mapping systems identify the system perimeters and provide an intelligent monitoring system. Mapping needs to have the capability to define the access control rights for software system actions.

Cloud computing provides the capability for faster development and reduced upfront investment. Hybrid cloud can help achieve the delivery goals by enabling development resources to be available on demand. Deployed services can be increased and decreased based on usage volumes for enhancements, releases, and upgrades.
Cloud Service Brokers are increasing in the Cloud space. Enterprises are looking for expert advice for management and improvement of the cloud-based application infrastructure. Cloud environments provide a collaborative, productive environment for participants in the business ecosystem. Collaborative working is enabled by cloud-based tools for email, instant messaging, voice communication, information sharing and development, event schedule, and conferencing. Broad Network Access is widely used on mobile phones, desktops, and browser-less devices. Manageability is provided by the cloud environments through the ability to provision and configures resources through a web portal. Resource provisioning and configuring can be done without a heavy management burden through self-service applications.
Benefits of Cloud Computing
Business continuity and disaster recovery can be achieved through geographically separated duplication and recovery mechanisms at a low cost. Server consolidation, thin clients, and community cost-sharing are the other cost reduction techniques through cloud computing. Cloud computing helps in shifting CAPEX to OPEX for an enterprise.
Community cloud has features for enterprise communities to share costs of common resources. This approach can be cost-effective through viable payment and governance model creation. Cloud is being used for big data and machine learning use cases.

Intel is working on creating a custom chip for Amazon's future cloud hosts. IBM power ship is being shared with a group of companies. AMD is planning to design custom chips for Facebook, Microsoft, and Google. Cloud computing is accelerating the creation of new products and services for enterprises by providing powerful and economical resources. It helps enterprises to do better decision-making by providing the capability for storing and mining data for trend and forecast information. The key factors that enterprises are concerned about are security, privacy, vendor lock-in, and loss of IT control/ownership.
IBM predicts that in the coming years, one trillion cloud-ready devices will be connected to the internet. The cloud-ready devices will be mobile devices. Mobile devices are providing seamless access to email and other content for daily jobs. A mobile-first environment will give the advantage of higher productivity to the enterprise. Enterprises have seen a pivotal role for the cloud in the Internet of Things. The obstacles to embracing the cloud have been security, performance, usability, and skill-related issues. IoT applications and services in the cloud connect to IoT sensors with a series of other cloud-based services. Cloud Storage is important when the Big data applications related to IoT are deployed on the cloud.
