SaaS, PaaS or IaaS: start with responsibilities
Understand cloud service models through the work your team wants to do, the control it needs and the operating responsibilities it can support.
Run and modernise
The useful question is not simply which cloud to choose. It is what your organisation needs to run, who should look after each part and what you need to count on as demand changes.
Software as a service, platform as a service and infrastructure as a service leave different responsibilities with your team. Managed services can add agreed operational support. Content delivery is another part of the picture when your audience needs fast, consistent access to public media and applications.
Discuss deployment, access, updates, scaling, migration, retention and retirement together. A change to compute capacity may also affect storage, network paths, software licensing, backup requirements and costs. The service agreement should make these dependencies understandable.
Vyoma is the cloud-focused part of the conversation. Gopsco can connect relevant business and digital needs around it. Shared access should cover only the services you authorise; it should not turn separate organisations or accounts into one shared pool of permissions.
A useful next step
You don’t need a finished specification. Start with the information you have and the questions you need to resolve.
