IBM introduced the first mid-range computers/servers called the system/38 in 1978 for enterprises. These hardware systems have evolved to System 36 in 1983, AS/400 in 1988, iSeries in 2000, system I in 2006 to the IBM Power Systems in 2008, which users are leveraging today.
Hardware: Upgrading can cost a lot of money for organizations as these IBM machines don’t come cheap. Say if you are using a power 8 technology server and want to upgrade your OS to IBM i version 7.5, you would have to buy a new server with Power 9 processor as the Power 8 servers don’t support this OS version.
An IBM Power System server S914 model with low end configuration costs around $14000. This is just the hardware cost and doesn’t include the installation cost which implies application and data migration from old server and other installation charges. These are extra charges and might amount to $5000. Remember that you would have to do this all over again every time your hardware requires an upgrade due to newer OS versions or as new applications are introduced which require more processing power.
Software: Software licenses should be purchased by the company from IBM to install the new OS and other necessary drivers for the new machine. A one-time license fee would be charged for this. Every time there is a critical software upgrade IBM charges a certain fee.
Any server, be it on-premise or on the cloud requires a robust HVAC system to make sure they don’t overheat or have any other hardware failures. Servers require constant monitoring by personnel for changing hard drives, monitoring cooling systems and other machine faults to ensure uninterrupted service.
Hardware of any kind has to be subjected to maintenance and the AS400 servers are no exception. This can be expensive and hardware failure which is caused by fried processors or motherboard and other crucial parts might take a hefty toll on the IT budget of the company.
Resource utilization of application have to be done manually by personnel of companies leveraging an iSeries hardware. No tool kit is given.
Companies need to hire IT technical staff to develop, test and deploy DR strategy along with separate hardware for data storage.
As you are aware, all the cloud providers be AWS, Azure, Google or IBM don’t charge extra for server maintenance and upgrade. The annual subscription you sign up for is all you have to pay. Hardware upgrades are inevitable as newer applications with unpredictable demand are introduced into the server and new OS that supports only beefy servers. Cloud can accommodate new applications with varying demands due to its scalability factor and the cost is significantly less than an on-premise upgrade as cloud has pay only for how much you use policy.
Server maintenance such as OS, disk usage, hardware errors and more are done by the cloud vendors.
HVAC is taken care by the cloud vendor. The annual subscription or monthly cost is well below the on-premise setup.
Cloud management tools are given to each organization to manage their applications and track utilization of resources to optimize performance and save costs.
The cloud provider will take care of the backup, failover, and failback services and maintain your backups in a safe and secure data center.
Re-hosting the application and data on the cloud and dumping the hardware won’t be time consuming, since the coding involved is negligible.
During the re-hosting, the code modification is kept to a minimum. Applications need to be recoded while moving the application to the cloud. However, with lift and shift approach unlike application re-engineering which is extensive and time consuming, changes to application code is negligible, hence, it involves low risks.
Heavy duty applications require more processing power which in turn requires beefy hardware, which increases cost. Moving to cloud has the option of scalability which helps to accommodate newer applications without significant cost.
Above are all the reasons why organizations leveraging iSeries on-premise servers should consider AS400 migration to improve business process efficiency and save cost.
Nalashaa has been helping multiple organizations leveraging AS400/iSeries systems with migration, modernization, and support needs.
