How do you make sure that your cloud stay is smooth and safe and you don't have to make the painful decision of jumping back to an on-premise setup? The below 6 points will help you take the right decision as well as be prepared.

1. Your current systems availability levels.

Do you know how available your current systems(and applications) are? Knowing this will be a good starting point in your cloud journey and will help you define the availability levels commitment you need from your cloud service provider.

Are the availability levels good enough for your end users/business teams? This will help take care of the expectations shooting up once you migrate to cloud.

2. SLA levels(Uptime, response and resolution time, etc). committed by the cloud service provider

The uptime committed by cloud computing service provider should be better than your current setup since there can be factors that can impact the availability like outages in connectivity, downtime due to config/setup errors introduced by your teams and so on. You need to consider this since your current system availability would have been calculated factoring the above.

3. Your existing DR and how it is going to be after migration to cloud

Do you have a DR for your current setup? Is there a BCP in place? How is the DR and BCP going to be configured once you move to cloud?

Will the time taken to failover to DR in case of outage will be same/better than your current setup?

4. Migration effort, time and the costs involved

Have you calculated the time and effort required for migration to a cloud environment as well as back to on-premise setup if required. What are the costs involved in doing the migration?

5. Support from cloud service provider

What is the type(email, phone, ticketing process, escalation,etc) and quantum(office hours, 24x7 and so on) of support you will get from cloud service provider?

6. Business driver for going to cloud IAAS...Cost, speed, scalability,etc.

Last but not the least, be clear on why you want to move to Cloud. Are you doing it purely for saving in costs? Or paying on a monthly basis(Opex) instead of Investing(Capex) for the complete infra is the key influencing factor?

Or are you moving to cloud to use the ability to deploy new servers quickly and release them if not required?

The answer to the above will decide whether you are getting a good ROI(Return on investment) by adopting cloud computing along with acceptable service levels which in turn will help you take the right decision.

If you are under the belief that your systems and application availability is assured by adopting cloud computing then you should read my to know the multiple outages each one of the big cloud providers have had. クラウドサービスのBlueSpider
