Cloud Orchestration is the process of automating the tasks needed to manage connections and operations of workloads on private and public clouds. Cloud orchestration technologies integrate automated tasks and processes into a workflow to perform specific business functions.
Cloud orchestration tools entail policy enforcement and ensure that processes have the proper permission to execute or connect to a workload. Typical cloud orchestration tasks are to provision or start server workloads, provision storage capacity as needed, and instantiate virtual machines (VMs) by orchestrating services, workloads, and resources in the cloud.
Cloud automation and orchestration tools help to reduce the challenges organization have had deploying automation tools by eliminating islands of automation in favor of a cohesive, cloud-wide approach that encompasses both public cloud and private cloud components.
The rapid adoption of containerized, micro-services based applications that communicate via APIs has created the demand for automation of deploying and managing applications across the cloud. This increasing complexity has created the demand for cloud orchestration software that can manage the myriad dependencies across multiple clouds, with policy-driven security and management capabilities.
As organizations increasingly adopt a hybrid cloud architecture, the need for both public cloud orchestration and hybrid cloud orchestration has continued to grow.
Most importantly, cloud orchestration reduces the need for IT staff to manually handle automation tasks, freeing up resources for more productive works. This also reduces the opportunity for manual errors to occur. This lets organizations spend time on innovation, enabling accelerated deployment of applications across hybrid IT infrastructure, orchestrating various processes across domains and systems. The result is an improved experience for users and customers enterprise-wide.
Cloud orchestration simplifies automation across a hybrid cloud environment while ensuring that policies and security protocols are maintained in a dynamic, modern IT environment. Cloud orchestration reduces overall costs while accelerating delivery of services, automates management and coordination of complex hybrid environments, eliminates provisioning errors, and enables self-service provisioning of services without the need for IT intervention.
Cloud orchestration can also help prevent VM sprawl by enhancing the visibility into resource usage across clouds. Other high-level benefits include automating connections between workloads to ensure links are configured properly, and many cloud orchestration platforms do so by the use of a web-based portal that offers single pane of glass management organization-wide.
In advanced organizations, developers and line-of-business workers can turn to cloud orchestration software as a self-service mechanism to deploy resources; administrators can use it to track the organization's reliance on various IT offerings and manage chargebacks.
Detailed benefits of cloud orchestration include:
Cloud Director orchestration models let you provision a ready environment to deploy virtual servers. Orchestration can be either single cloud or multi-cloud. In a single cloud model, multiple applications run on the same cloud service provider, which is a simpler setup. The more complicated, but also more powerful model is the multi-cloud setup. Here we have multiple applications, which are located on different cloud platforms, and multi-cloud orchestration interconnects them so they can perform as a single system, with the advantage of high redundancy.
There are also three delivery models for cloud services in general, Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS).
IaaS is most commonly utilized in cloud orchestration environments. IaaS providers offer network hardware, storage, and servers, as well as physical security in either a dedicated or multi-tenant environment. IaaS providers also offer virtualization services and orchestration tools that can streamline IT operations within their cloud or between multiple clouds.
PaaS providers also provide operating systems and middleware, and SaaS providers deliver applications only, through a web interface, typically on a subscription basis.
Cloud orchestration tools enable all these models to operate as one, providing automation across models and across clouds, but typically taking advantage of IaaS providers to automate the deployment process, reducing labor and resources required so they may focus on bottom-line generating functions.
Orchestration is a superset of automation. Cloud orchestration goes beyond automation to also provide coordination between multiple automated tasks. Automation, on the other hand, has the goal of enabling one task, such as initiating a web server, to be repeated or iterated quickly with little manual intervention. Thus, cloud orchestration focuses on the entirely of the IT processes, automation on a single piece.
Practically, cloud orchestration and automation work hand in hand to ensure that cloud-based applications and services are deployed and delivered in a cohesive, functional, cloud environment that operates efficiently and cost effectively.
Cloud orchestration adds enterprise-wide functions such as redundancy, scalability, failover and fail-back, manages dependencies, and bundles them into a single package, greatly reducing the overall IT burden. Orchestration additionally offers enhanced visibility into the resources and processes in use, which can help prevent VM sprawl and help organizations track resource usage by department, business unit, or even by individual user. Orchestration enables automatic scaling of distributed applications, disaster recovery and business continuity, and inter-service configuration.
Cloud orchestration is increasingly important due to the growth of containerization, which facilitates scaling applications across clouds, both public and private. Tools such as VMware Tanzu help facilitate container orchestration across an organization’s entire cloud presence.
