Oftentimes when I speak with IBM i users about moving to the Cloud, they tell me it is too expensive. When I dig deeper, I find out that they are simply comparing the cost of buying a machine on-premise and paying hardware and software maintenance costs vs paying for the same machine in the Cloud. By doing that, they are missing out on most of the significant value and potential cost savings provided by moving to the Cloud. And I am not just talking about the potential cost savings in physical infrastructure (datacenter space, electricity, cooling, cabling, security, etc.) Moving to the Cloud allows you to completely rethink how you manage your computing resources. Cloud advantages to consider include:
1. Buy the minimum hardware capacity needed and expand when necessary
When you buy systems for on-premise computing, you must buy enough capacity to handle peak processing requirements. Companies cannot afford to have systems that perform poorly or go down because of spikes in demand. Because of this, I find many customers running systems operating at 50 or 60% capacity. In the Cloud, you can buy the minimum amount of resources you need for day to day computing and then expand on demand. With just a few mouse clicks, you can add disk capacity, processing capacity, memory, additional web servers – whatever you need. You can even have these configuration changes occur automatically in response to usage or on a schedule. You can buy resources by the hour, by the day, by the month and only pay for what you use.
2. No-hassle Hardware Upgrades
Thanks to the IBM i’s High Level Machine Interface, hardware changes can be made without impacting your applications. However, if you are running on-premise, you must buy the new hardware, schedule the installation and manage the installation impact. If you are running in the Cloud, your Cloud provider does that for you. Your organization can constantly reap the benefits of new technology without business impact.
3. Geographic HA/DR Distribution
Most Cloud providers allow you to select the regions where your systems will be running. You can easily setup your HA/DR systems in separate regions from your production environments. Should there be a regional disaster (eg. a hurricane, tornado, major fire or earthquake) you can immediately switch to machines outside the impact zone.
4. High Speed Hardware replication for HA/DR and Analytics
If you want to take advantage of the speed offered by hardware replication for HA/DR or to allow for near real-time analytics without impact on production, you can do that in the Cloud. Since replication is cloud to cloud and requires no low-bandwidth public internet connections, the secondary machine will always be very close to an exact copy of the primary machine.
5. Low cost Backup on High-Speed Cloud to Cloud Connections
Backup to the Cloud and take advantage of the low cost storage options and online convenience offered by companies like IBM, Amazon, Microsoft and Google. It gives you all the convenience of a VTL at a fraction of the cost.
6. On Demand Access to Expert Resources
Take advantage of your Cloud provider’s IBM i experts. They can do operating system upgrades, security audits, application upgrades and manage operations. Many also offer additional services like application development and modernization. In addition, this gives you a pool of ready resources as your IBM i staff reaches retirement.
7. Manage Resource Use
Set limits on memory usage, processor usage, by user. Allow for internal user self-service. Users can create the test partitions they need when they need them without overusing corporate resources.
8. Easy, Fast Cloning

9. Comprehensive Access to Audit information through reports or APIs
Track exactly who is using which resources and for what. Generate a variety of usage audit reports
And there is more!
So, if you have not yet considered the option of running your IBM i in the Cloud, the new Cloud options might make it a good time to do that.
