Here are just a few of the many questions, we are asked and happy to answer at Digital Innovations Global, from potential customers interested in moving their IT systems and applications to the cloud.
1. Can you tell me what’s the difference between SaaS, PaaS and IaaS? The differences between the three cloud service models are as follows:
- IaaS cloud services offers the ability to design and deploy cloud infrastructure that can run the most range of on-premise applications.
- PaaS cloud services include operating systems, software, middleware and support, without and need to design and deploy IaaS cloud infrastructure.
- SaaS cloud services deliver alternative cloud based applications, which are similar to on-premise applications, e.g. Microsoft Office/Exchange to Office 365.
2. What’s the difference between Public, Hybrid and Private cloud? The differences between the three clouds are as follows:
- Public cloud based on the standard cloud computing model, in which a cloud service provider makes resources, such as servers, applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.
- Hybrid cloud is an integrated cloud service model utilising both private and public clouds to perform distinct functions within the same organisation.
- Private cloud model used to describe a cloud computing platform that is implemented within the corporate firewall, under the control of the organisation’s IT department.
3. What is the best time to migrate to cloud servers? The best time to migrate is NOW!, ok not right now, but after you have first analysed all your applications and servers resource usages and made and agreed a migration plan. This will help you to estimate the cloud migration costs for the applications and determine whether they can be shared with other applications, or separated to run on their own virtual centralised cloud servers for ease of support.
4. What is the best cloud service provider? The best cloud service provider in our opinion is the one that offers the most suitable range of cloud services that match the customer's application and compute requirements.
5. What applications will not be able to be migrated to the cloud? The only applications that are not able to be migrated to the cloud, are those we find that are not compatible with the cloud service providers compute services, APIs etc. Even large storage and heavy SQL workload applications are able to be migrated after some analysis and remedial work is performed.
6. Isn't cloud computing expensive? Compared to on-premise IT Infrastructure, NO cloud computing is not expensive, no datacentre costs, no servers to provision and no maintenance or support costs to pay.
7. Can we pay in advance to access the cloud systems, to save money? Yes, but this depends upon your cloud implementation model. There are various payment options offered by the cloud service providers:
- Pay-as–you-use, with no upfront fees.
- Fixed contract.
- Reserved Instances with discounts.
8. How will I be able to tell if moving to the cloud is working well for us? Based on the business factors driving your cloud migration, the critical success factors should be very easy to determine:
- Savings in CapEx over the next 1 to 5 years.
- Server to staff ratio improved.
- IT maintenance contracts cancelled.
- Faster product launches.
- Reduction in operational support calls.
- And many others…
9. Where did your team learn about cloud infrastructure? From 20 + years delivering major on-premise IT Infrastructure projects, learning from vendor cloud courses and by years of on the job training.
10. How long has Digital Innovations Global been involved in IT Infrastructure? Digital Innovations Global have been involved in major IT infrastructure projects around the world since the early 1990s, working on major IT related projects for many customers worldwide.
11. How many cloud implementations has Digital Innovations Global done in the past? Digital Innovations Global have implemented cloud solutions for small marketing websites to major $10bn UK Government projects.
12. How long has Digital Innovations Global been involved in cloud computing? Digital Innovations Global infrastructure Architects or “Diggers” have been involved in cloud computing since the early days of AWS, about six and half years in total, but before then we were also involved in large scale on-premise private cloud web portal projects and datacentre migrations from the late 90s.
13. How to I choose the best applications to move to the cloud? This question can only be answered by analysing your current IT systems and applications, to identify those first that have a low resource usage, and low storage requirements. The other applications that have higher resource usage and/or need large storage requirements, will need more in-depth analysis before moving them to the cloud.
14. Can I move back my applications and data from the cloud, if it doesn't suit our business? Yes sure, your data is always owned by you, it’s never owned by the cloud service provider.
15. What’s the difference between AWS and Azure? AWS is the cloud service offered by Amazon Web Services, Azure is the cloud services offered by Microsoft. They both offer Microsoft and Linux cloud systems, with AWS having the largest number of 47 cloud services available.
16. How long does it take to move to the cloud? The easy answer is how long is a piece of string, but usually it depends on how big or small the on-premise IT infrastructure is and how quick the IT systems and applications can all be identified and profiled.
17. Does your company do cloud infrastructure training? Yes, we offer one-to-one or class based training to all our clients IT staff as part of our cloud migration services.
18. How secure is cloud computing, you hear so many stories? Cloud computing, if it has been set-up correctly is probably the most secure IT computing environment available today.
19. Is there any limits to what can be moved to the cloud? The only limits on how much on-premise IT Infrastructure and applications that can be migrated to the cloud is your OpEx Operating Expenditure budget limit, that will be significantly a lot less than your current CapEx Capital Expenditure budget.
20. Will I need to purchase special equipment to access the new cloud infrastructure? Usually no, the majority of access to the cloud management console is done using a PC with a browser.
21. How soon will I see a return on my Investment in using the cloud? You should see a return on your investment within the first year, with the largest returns in year five.
22. Will my IT users see a difference in application performance e.g. slower or faster response times? Yes, they will depending upon the solution implemented, they should see a marked increase in application response times, and your customers will also see an improvement. They should not see any reduction in application response times.
23. How much will it cost for your companies services? This question can only be answered after an pre-sales consultation, to understand fully the business factors supporting your decision to migrate to the cloud.
24. Who owns Digital Innovations Global? Digital Innovations Global is the trading name of Datadean Limited, a UK based strategic consulting company specialising in IT Infrastructure and data communications which was incorporated in May 1994, is now owned by David Dawkins and Chetan Kotecha.
