FEATURE integration between environments and allow developers to use resources in your hybrid cloud without extensive retooling. Establish relationships with cloud providers even if your need for them isn’t immediate (which will save you time down the road). Decision 4: Deciding which apps and services run on which cloud Decisions on where to place certain workloads with certain CSPs will depend on things like price, elasticity, security and compliance requirements, and unique application needs. When it comes to public cloud, there are a handful of widely- used options that offer a compelling range of infrastructure and service choices. The key here is to select public clouds that work optimally with your chosen cloud operating environment and complement your app environment. (As an example, Microsoft Azure might make more sense for enterprises invested in Microsoft than enterprises running Linux). Consider also the levels of customisation, service and support that CSPs provide. Decision 5: Making a shortlist of SaaS providers This decision is lower priority than data centre modernisation and selection of CSPs and public clouds, but it’s worth thinking through SaaS considerations at this point.

A good example is looking at all the internal messaging services you’re utilising – do you really need Slack, Jabber and Jive? Think about the possibility of outsourcing some apps you’re running on-prem today to SaaS providers to free up staff and infrastructure. Also, don’t forget about the data being stored by SaaS providers and make sure that regulatory and data protection requirements are being met. JON LUCAS, CO-DIRECTOR, HYVE MANAGED HOSTING Although some businesses will go all-in with either public or private cloud, this isn’t a model that works for everyone. Different workloads and applications are suitable for different types of cloud. Hybrid cloud is a great answer to this. But it is important for every organisation to first understand the difference between hybrid and multi-cloud before dipping their toe in, because getting one confused for the other could lead to a disappointing outcome. Both hybrid and multi-cloud involve using a mixture of public and private cloud to maximise efficiency, cost and scalability – the differentiator is in how they are integrated and managed. Multi-cloud consists of a series of different clouds that are centrally managed in a single architecture. These cloud environments can be either public cloud, private cloud or a mixture of both and are provided by a range of suppliers and therefore have to be managed internally, adding to the responsibilities of the IT team. Operating in a multi-cloud environment results in different configurations, settings, pricing plans and multiple invoices – making management and budgeting more complex and time consuming. In comparison, hybrid cloud is a single entity and consists of a combination of on-premises, private cloud and public cloud, working together in tandem. This is provided by one supplier and means businesses are operating within a single cloud infrastructure. As with multi- IT IS IMPORTANT FOR EVERY ORGANISATION TO FIRST UNDERSTAND THE DIFFERENCE BETWEEN HYBRID AND MULTI-CLOUD BEFORE DIPPING THEIR TOE IN. cloud, the most appropriate cloud can be used for different workloads and data. Having all of the operations within the same infrastructure unifies IT and it can therefore be managed more effectively. Organisations will find that hybrid cloud provides the best of both worlds for businesses and working with a managed cloud provider means that the correct workloads will always be in the most suitable environment. Public cloud will be utilised for intensive workloads and is ideal for running test and development servers, for example, and for sensitive data, the private cloud will be used. Having this all centrally managed by an experienced managed cloud provider will mean businesses can fully embrace the hybrid cloud model – avoiding the siloed approach of multi-clouds. ◊ Jon Lucas, Co-Director, Hyve Managed Hosting www.intelligentdatacentres.com
