The document discusses the inevitability of multicloud environments and the need for collaboration between cloud providers. It notes that enterprises have requirements around security, availability and integration that make using a single cloud vendor infeasible. As organizations adopt cloud services over time, they progress from using basic SaaS to integrating private and public clouds. However, true multicloud integration faces challenges around cross-cloud communication and standardization. The document argues that cloud integration middleware and standardization are needed to reduce vendor lock-in and enable multicloud, though competition may currently limit collaboration between providers.

What is the Problem?
Dependencies
An enterprise application is usually
integrated with tens if not hundreds
of other applications
Migration
To reduce risks transforming of
enterprise IT-Landscapes to cloud takes
place over long timeframe
Heterogeneity
Usually an enterprise has many platforms
(C++, SAP, .NET, JVM)

7. November 10, 2015Tarmo Ploom/15-010878 7
Inevitability of Multicloud
Even small SMB-s have use five
or more cloud environments
Enterprises will use mixture
of SaaS, PaaS, IaaS
Technology dependent clouds
(.NET, JVM, …)
Legal requirement – avoidance
of catastrophic data loss
Just using single cloud vendor
is not feasible, enterprises will
have their and SaaS applications
on different clouds

Conclusion
To support transformation towards
multicloud environments
– Emergence of cloud integration
middleware is needed
– Standardisation of cloud application
infrastructure is needed
– Standardisation of cloud application
services is needed
It means cloud vendor lock ins mechanisms
have to be replaced with standards
However CAGR of cloud computing is ca 20% -
economic driver for collaboration may be missing
