Increasingly, users are turning to hybrid cloud computing infrastructures for the deployment of their applications. Cloud federation, cloudbursting, and cloud brokering are some of the most popular models for combining multiple cloud computing providers into a single infrastructure. This webinar we discuss how the Fogbow middleware can be used to support different cloud combination models, both from the end-users’, as well as the cloud providers’ perspectives. Francisco Brasileiro will present the main features provided by the middleware, and how it can be easily customised to combine multiple clouds, running different cloud orchestrators. Leandro Ciuffo will talk about RNP’s (the Brazilian NREN) plans to adopt Fogbow for the federation of clouds, and to enhance the portfolio of services that RNP offers to its community of users. https://www.atmosphere-eubrazil.eu/combining-clouds-fogbow

4. Fogbow in a nutshell
• Fogbow is a microservice-based midleware
that supports multiple ways to combine
clouds, including:
– Cloud brokering
– Hybrid clouds
– Federated clouds
• Open source
• Completely customizable via plugins

5. IaaS deployment models
• Public cloud providers
– Shared multi-site infrastructures
– Economy of scale leads to very efficient providers
– Provides higher elasticity to users
– Pay-as-you-go pricing scheme reduces upfront
investments to users
– Might raise security and privacy concerns
5

6. IaaS deployment models
• Private cloud providers
– Dedicated (typically) single-site infrastructures
– Brings no new security and privacy concerns
– Smaller than public providers, thus tend to be
less efficient
– Normally, less elastic than public providers
• More restrictive usage quotas
6

7. Combined deployment models
• Multi-clouds (brokers)
– Allow multiple public clouds to be used,
increasing the portfolio of services available to
users
– Allow resource allocation driven by some
objective function (eg. minimize cost)
– If implemented in-house, may mitigate vendor
lock-in issue of public clouds
7

8. Combined deployment models
• Hybrid clouds
– Typically, extends the infrastructure of a private cloud
by allowing some of the workload to be outsourced
to a public cloud
– Improves the efficiency of the private cloud
– Provides access to multiple geographically distributed
sites
• Useful for fault tolerance and attend geo-sensitive
workloads
– Sensitive workload might need to run in the private
part of the infrastructure
8

9. Combined deployment models
• Federation/community of private clouds
– Shared multi-site infrastructures
• Fine control on how sharing is performed at each
autonomous site (from the providers point of view)
– Depending on how members trust each other,
may not raise extra security and privacy concerns
– May allow for higher elasticity
– More flexibility in defining business models
