Hybrid cloud adoption
Enterprises will pick and choose applications and vendors based on their business needs, thus creating a diverse and heterogeneous cloud environment.
Some of the aspects of cloud infrastructure working in sync with on-premise or private environments include:
- Federated identity and security. A critical issue for enterprise customers wanting to avoid the problem of ‘shadow IT’. Shadow IT occurs when applications and data are moved out of the IT department’s control and users need alternative log-in credentials to access the data. This creates problems for data protection compliance and privacy.
- Workload optimisation. Used as part of the cloud migration process, it provides a baseline for establishing the resources required in the cloud and the cost of running the application. This should be a key element in negotiating an SLA with a cloud vendor.
- ‘Cloud-aware software’. Mainstream software vendors, large and small, are currently rewriting their software to make it ‘cloud-aware’. In-house software must also be cloud-aware by using asynchronous messaging and supporting multi-user and multi-tenancy. This can be achieved by using the latest development tools that support cloud as a deployment platform.
- Middleware. This is the integration ‘glue’ between applications in the public cloud and the private cloud. It makes it easy for software developers to connect software on local and remote platforms.
- Managing metering and billing with multiple cloud vendors. Still a significant challenge but the use of federated management tools to link cloud and on-premise IT are making it easier. These have to be able to support multiple cloud providers to create a single view of all platforms to ensure effective billing.

This is part 5 in a serie of posts where I explore the case for hybrid clouds. I will highlight how system integrators and service providers can address these developments as an extension of their existing business model and bring IT to the new cloud reality. Finally, I will outline the importance of choosing the right type of data centre in which to build your cloud solution.
