3. Technical requirements
In order to understand how you can operate more efficiently in a public cloud environment, it makes sense to first understand your current IT infrastructure. It might be appropriate to keep some workloads on-premise – for example workloads that have very low latency requirements, or that have heavy dependencies on complex third party integrations – rather than migrating all workloads to the cloud. You will also need to factor in integrated or legacy systems and the inter-dependencies of these systems. Without the right evaluation of all your systems, your liable to a chain reaction if something goes wrong. You should also assess the compatibility of existing software and hardware to identify opportunities to utilise your existing assets or make any upgrades required.
4. Changes to licensing models
One of the key advantages of cloud is that customers are able to pay for resources on-demand. Bills are issued to reflect consumption in the previous month or quarter and therefore based on actual consumption rather than estimated costs. If more services are used then the bill is higher. But similarly, by applying scripts so that business VMs and apps are placed offline at night, then consumption can be reduced.
However, this requires shifting from a capEX agreement to an opEx one such as Microsoft Cloud Solution Partner (CSP). Trustmarque currently supports consumption of Azure services through the CSP platform. It is a flexible and cost-effective way to consume Azure that gives you full visibility of all your cloud-based desktops, apps and infrastructure licenses.
5. Cloud security, risk and compliance
Cyber security is an important consideration when looking at migration to a public cloud environment, as it is with on-premise datacentres, your cloud infrastructure and apps are also vulnerable to malware and exploits. While moving to the cloud doesn’t quite carry the fear that it once did, a vigorous approach to cloud security is crucial for every organisation’s digital roadmap and governance practices. It’s vital to ensure all end points and networks are protected, whether in the cloud or in a hybrid cloud environment.
As with on-premise data centres, your cloud infrastructure and apps are also vulnerable to malware and exploits. You need to consider your current security environment (firewalls, RBAC, DMZs and more) and what your new public cloud environment will look like. Consider your cloud-based perimeter firewalls, application gateways and identity to ensure all end points and networks are protected.
Compliance can be a key area also, when moving to the cloud. Many organisations need to meet the needs of the FSA, HSCN or other considerations. As such, environments need to be set up with some forethought. GDPR requirements also make it important that compliance and data retention are taken into account while setting up a cloud environment.
