Solution Overview¶
Cloudlets represent an architecture of federated cloud that have a CMP+Automation+PaaS+CloudOS bundle as described in the C3 architecture. The architecture targets cloud operations managers and should be as transparent to the end user and developer as possible.
Logical Architecture¶
What is the smallest size of the data for a cloudlet to: Authenticate all users in the cloud federation All other data required to run any job or at least start a job remotely.
This should help answer the storage requirements for the Cloudlet.
Where is data impacted: 1. Data Latency? 1. Does data Gravity have a big play 1. What VMs do you want localized 1. What images are required on the Remote Clouds 1. Updates to Cloudlets.
- Cloudlet Manager - Each Cloud Has a Cloudlet manager that becomes part of the Federation
- Federated Orchestrated Cloud - Federated Orchestrated to schedule service requests acrosss multiple clouds
- Data Coordinator - Coordinates data between Clouds
- Identity Manager - Manages Identity across multiple clouds
- Trust Manager - Manages Securee keys in TPMs across multiple data centers.
- Telemetry - Aggregates Telemetry before forwarding it own to a cloudlet telemetry
- C3 - Common Cloud Core including a Cloud Management Platform
Process Architecture¶
There are several activities that an Operations Manager performs with the Cloudlet Architecture including: Setting up the federation of clouds to form cloudlets, Establishing Local and Global (Federated Policies), Creating Secure geo-fenced domains, and updating and patching infrastructure across the cloudlets.
Deployment model¶
The Cloudlet architecture should be as light weight as possible and should integrate existing infrastructure and systems with minimal impact on the current system. Existing cloud installations are used to handle the heavy lifting in the system. The cloudlet architecture requires a hybrid cloud architecture that includes Cloud Management Platform, Automation Framework & Platform as a Service, or the functions defined in those sets of tools.
The Cloudlet Architecture has a Cloudlet Manager is that placed as a connectivity layer between the hybrid cloud and the Federated Connectivity. The connectivity gives all of the functionality that is needed to federate the different clouds systems together. This let’slets the cloud operate independently from other cloud(s). Allowing for them to operate in a disconnected or semi-connected state.
Physical Architecture¶
The goal of the architecture is to connect multiple clouds together that are scattered across an organization. This could be physically as well as logically. There is the concept of a base Cloud that could offer multiple clouds and remote clouds named cloudlets.
