Cloud hub architecture

  1. 1. CloudHub Architecture Shanky Gupta
  2. 2. Introduction  CloudHub has been built from the ground up to provide enterprises with a multi-tenant, secure, elastic, and highly available integration platform as a service (iPaaS). This document describes how the underlying mechanisms of the CloudHub platform work to achieve these goals.  CloudHub is managed via the Runtime Manager console, in the Anypoint Platform. You can also deploy to it directly from Anypoint Studio, via the CloudHub API or via the CloudHub Command Line Interface.
  3. 3. The Architecture  To understand CloudHub’s approach to security and availability, it’s important to understand the architecture behind CloudHub. It includes two major components: the platform services, and the worker cloud. These two components and the Runtime Manager console through which you access them work together to run your integration applications.

  5. 5. Integration Applications  These are applications that you create and deploy to CloudHub to perform integration logic for your business.  An integration application is any integration that you’ve built using Anypoint Studio. These applications can do everything from synchronizing data from Salesforce to a database, to publishing a SOAP or REST API, to creating complex orchestrations of business processes.
  6. 6. Management Console  The Runtime Manager console is integrated into the Anypoint Platform. Sign in with your Anypoint Platform credentials to upload and manage your integration applications at runtime. The console surfaces useful monitoring information from the platform services and also works as a comprehensive dashboard for both application-level and account-level management.  Through this same console you can deploy to CloudHub as well as to other registered servers. You can also manage deployed applications.  Administrator account holders can use the Anypoint Platform to add and manage other users in the organization, define user roles, and create and manage sandbox environments.
  7. 7. Platform Services  CloudHub’s platform services are responsible for coordinating all aspects of the platform. They coordinate deployment of applications, monitor integrations, provide analytics data, store application data, run scheduled jobs, and more. Many of these services are also exposed through the CloudHub REST API.
  8. 8. CloudHub Workers  Applications on CloudHub are run by one or more instances of Mule, called workers. These have the following characteristics:  Capacity: Each worker has a specific amount of capacity to process data, you can select the size of your workers when configuring an application.  Isolation: Each worker runs in a separate container from every other application.  Manageability: Each worker is deployed and monitored independently.  Locality: Each worker runs in a specific worker cloud, the US, EU, Australia, etc.  Each worker is a dedicated instance of Mule that runs your integration application. Workers may have a different memory capacity and processing power depending on how you configure them at application level. Workers can be scaled vertically by selecting one of the available worker sizes:  Worker Sizes:  0.1 vCores + 500 MB Memory  0.2 vCores + 1 GB Memory  1 vCores + 1.5 GB Memory  2 vCores + 3.5 GB Memory  4 vCores + 7.5 GB Memory
  9. 9. Global Worker Clouds  CloudHub offers different worker clouds in different regions of the world: the United States, the European Union, and Australia. This global distribution allows you to host your integration in a location that is closest to your services, thus reducing latency. It may also allow you to adhere with local laws, such as the EU Data Protection Directive. The management console and platform services are hosted in the United States.  When your application is running in the EU, all HTTP services are also available over the domain. For example, if you create the application "myapp", then its domain is "" This load balancer is hosted in the EU, ensuring that your data is never transferred outside the EU when invoking HTTP services.
  10. 10. Workers and Multitenancy  Because different levels of security and isolation are needed depending on the service, the platform provides two different levels of multitenancy.  First, the worker cloud is a multitenant cloud of virtual machines. These VMs provide the security and isolation needed for your integrations to run custom code without affecting others.  Second, the management console and the platform services have a "shared everything" architecture – all tenants share the same web UI, monitoring services, load balancers, etc. These services do no not process or transmit your data.
